Innovation never stops in the glassmaking sector

www.glass-international.com

T

he summer vacation is over and the glass industry has returned to work with a bang. The leaves on the trees have not turned Autumnal brown yet and already a number of events have taken place in the industry.

I’ve mentioned this before but the industry never really seems to stop, there always seems to be an important breaking news story or an exciting investment project to report on somewhere in the world. These investments of course keep suppliers of glass manufacturing equipment in business, while the glass producers benefit from the latest and most modern technology.

The plus point for both suppliers and manufacturers is that the final glass product made will have usually been made in a leaner, more energy efficient and environmentally friendly manner than before.

This gives everyone involved in glassmaking more ammunition in the ongoing battle against competitor materials such as plastics.

The subjects of new technology and of the competition were themes of the recent Glassman Europe conferences held in Lyon, France recenly.

The Future Glass Forum, focused on digital glassmaking, the other concentrated on Trends in Glassmaking.

It was useful to hear of some of the innovations in glass. A flick through both this issue and the Glass International website reveals how much innovation is taking place in the glass industry and the efforts being made to engage the end consumer. This includes O-I’s MyPour Artesanal bottle and FEVE’s ongoing Friends of Glass campaign, which has engaged 90 million people in the past three years about the benefits of glass as a packaging material.

The 18 papers from the event are available to download for free from the Glassman Europe website and offer a variety of knowledge about the sector.

Our highlighted interview this month is with Phoenix award 2017 recipient James O’Callaghan. Mr O’Callaghan has spent 20 years working with glass as a load-bearing material.

His work with Apple ensured that some of the software company’s stores and buildings are some of the most iconic of our generation - and all are made of glass.

He is a worthy winner of the award and hopefully his story is one that will inspire future generations of glass engineers. �

NEWS IN BRIEF

Glass packaging grows 2.9% in 2016

Glass packaging production in Europe grew by 2.9% in volume (Tonnes) and by 2.1% in unit terms in 2016 according to data published by the European Container Glass Federation (FEVE).

The growth was driven by exports as well as continued demand for glass packaging in food and beverage segments in Europe. A total volume of 20.9 million tonnes or 75.9 billion units were produced in Europe for the EU and international food and beverage markets.

“The buoyant demand for glass is a strong signal of trust from customers in our industry and in glass packaging to help brands stand out on the shelves both in the European market and internationally,” stated FEVE President Johan Gorter.

Gerresheimer CEO

Dr. Christian Fischer, 53, is to assume responsibility as Chief Executive Officer of Gerresheimer.

He succeeds Uwe Röhrhoff, 55, who left the company on August 31, 2017.

Dr Fischer joined the Management Board as a regular member on August 1, 2017, having previously been President Performance Chemicals at BASF in Ludwigshafen, where he spent 24 years.

As well as attendees from Verallia and O-I, France was represented by companies including Saverglass, Pochet du Courval, SGD, Danone Waters and Arc International.

Ken Clark, Glassman Sales Director said: “We have had good feedback from our exhibitors who have said it was a successful event.

“We believe that this has been one of the best Glassman Europe’s in recent years thanks to the quality of visitors and the geographical reach of the visitors who attended.

“I’d like to thank all of the exhibitors, visitors, conference speakers and the Lyon regional government who have helped make this such a memorable event.”

Orora completes Gawler expansion Australian packaging manufacturer Orora has completed an AU$42 million (US$33.8 million) investment project to increase glass bottle production at its facility in Gawler, South Australia, creating 26 new jobs.

The investment has expanded the glass bottle forming lines at the plant, increasing capacity by 60 million bottles per year.

Orora said the increase in

production will directly benefit the South Australian wine industry, which is enjoying a sustained period of growth, fuelled by exports to key global markets.

The Australian government recently unveiled a AU$50 million ($39.5 million) fund to promote the country’s wine exports and wine tourism.

Orora CEO Nigel Garrard said: “Orora’s Gawler facility is already one of the largest glass

manufacturing facilities in the southern hemisphere and this investment enables us to service the increased demand for high quality glass bottles.

“The expansion at Gawler represents one of Orora’s largest capital investments in Australia and helps underpin the long-term future of our glass business. The investment reinforces Orora’s commitment to be an innovative provider of packaging solutions.”

Verallia celebrates €12 million Cognac investment Introducing the Cleanfire® ThruPorte™ Burner A solution for aging regenerators Undergoing regenerator repairs or having difficulty maintaining full production in an aging furnace? Turn to Air Products’ Cleanfire ThruPorte Oxy-fuel burner for a quick, costeffective heating solution to avoid downtime or extend your furnace life. This patented and commercially-proven technology, installed from the underside of your port, allows you to add heat where and when it’s needed.

Key features:

Verallia’s Cognac plant has celebrated the restarting of one of the factory’s three furnaces, the one specialised in producing extra-flint glass.

Verallia said the €12m investment strengthens its territorial anchoring in Charente and its leadership as the reference glassmaker on the Cognac market.

Work on modernising the furnace lasted less than two months and mobilised around 50 business partners. The furnace and its four production lines were refurbished to increase the facility’s extra-flint output and flexibility.

Verallia’s Cognac plant serves three main markets: still wines, sparkling wines, and Cognac and spirits. Most Cognac producers, regardless of their size and their positioning opt for extra-flint glass, a colour unrivalled in terms of transparency and shine.

Christian Garnaud, Verallia Cognac’s plant manager, said: “With this new installation, we are increasing our capacity, our flexibility – notably for the production of large containers up to 4.5l, and our quality control. We have also taken care of the working conditions for our

teams: the lines are now equipped with hoists to reduce load-carrying, the site’s ventilation has been enhanced and we have refurbished the furnace control cabin at the hot end.”

During the traditional furnace lighting ceremony, the furnace was symbolically relit by Véronique Martial, PA at the plant, and Patrick Bernardet, furnace rebuild project leader at Verallia, who are now respectively the furnace’s godmother and godfather (pictured).

Pennine Industrial in UK opens Len Hobbs test facility Pennine Industrial has opened a new test facility, named after its founder.

The purpose-built facility will provide it with a dedicated building to run continuous long life trials under load, and with additional heat where required to simulate conditions that chains will experience when operating under hot glass.

The building has been named after Pennine lndustrial’s founder, Len Hobbs, who started the

company in 1968. Sadly Len passed away in 1989 but his philosophy and forward thinking still carries on three generations later as the company heads towards its 50th year of trading.

The new building was recently opened and is in use. A separate test rig within the new building allows high speed testing of general conveyor chains and power transmission.

The facility will also house equipment to test

individual components that can be subject to high impact load testing and, when required, Pennine can offer a pre-stretching service if a customer needs pre-stretched chains for demanding applications.

The opening of the new building also co-insides with the launch of Pennine lndustrial’s new 2 Pin Laser Welded HYPERDRIVE Conveyor chain.

The conveyor chains are now available to customers throughout the world.

Heye International has assisted Taiwan Glass with its conversion of four more production lines to Heye technology.

It also included the installation of a new Heye IS machine, featuring the company’s latest developments in Narrow Neck Press and Blow (NNPB) production.

Established in 1994, family-owned Taiwan Glass is Taiwan’s leading glass producer,

with diversified business interests associated with the manufacture of glass packaging, flat glass, solar glass and fibre glass.

A technical assistance agreement was signed with Heye International in 1983 and subsequently, the company has pioneered the NNPB process in Taiwan and the region.

In total, 11 Heye production lines are now operated at the Hsinchu glassworks after

a positive relationship developed between the experts of both companies in the past two decades. The factory operates a variety of Heye production machines.

This includes Heye’s Press Duration Control to minimise hot end defects, to provide reproducible wall thicknesses and to ensure high quality production.

Glass Futures requires larger site The UK’s Glass Futures project requires a larger facility for its operations.

Its advisory board said that, such was the amount of interest in the project and the additional resources required to support operations, it was searching for an alternative to the Magna site.

The group said there had been plenty of interest from industry, academia and other interested group in the proposed glass centre of excellence.

As a result the scope of the concept has increased to accommodate the extra needs of the supply chain, from raw materials through to the manufacturing processes and to the final glass products.

The Glass Futures team had originally selected a former steelworks and now visitor attraction called Magna, in Rotherham, UK as the home of the project.

The scheme is the brainchild of the British Glass association and, alongside in-

dustry and academic partners including O-I, Guardian, Siemens and Swavorski, it plans to create a hub of excellence for the global glass industry.

The proposed site will contain a 30MT per day oxy-fired furnace, which will supply glass for the production of containers.

Other sectors of the industry, such as float, fibre and tableware will also be able to benefit from the flexibility of the furnace as a test bed for ancillary equipment.

O-I to close Envigado plant and build new furnace in Colombia O-I is to close its Envigado plant in Colombia and build a new furnace in its Zipaquira site in the same country.

In a letter to employees the world’s largest container glass manufacturer said staff would be offered the opportunity to transfer to the Zipaquira site.

It said: “We want to ensure that our operation in Colombia continues to be competitive, sustainable and renewable for the future.

“As a result, we have made the decision to close the Envigado plant during the second half of 2018 and to construct a new furnace in our Zipaquira plant in Cundinamarca.

“This decision will allow us not only to obtain synergies but also to increase the capacity to serve our clients better.

The consolidation of our production of containers in Zipaquira, will create important economic, logistical and com-

mercial benefits.”

While most workers will be offered a transfer to Zipaquira, its administrative staff will be transferred to a new location near the current location in Envigado.

The Envigado plant has operated for more than 70 years.

O-I said the plant would work to the highest standards of safety, quality, productivity and cost until the last day that the plant operates.

FEVE secures awards

FEVE, the European Glass Container Federation, and Weber Shandwick Brussels won four Stevie Awards at the 14th Annual International Business Awards.

The pan-European Friends of Glass Endless Lives of Glass campaign won gold, silver and bronze, bringing a grand total of eight international awards for Friends of Glass since 2014.

Glaston closes US deal

Glaston Corporation has closed a deal with US-based Trulite Glass & Aluminium Solutions for a FC Series jumbo-size tempering furnace. The order is part of Glaston third-quarter expected order intake.

The line will be delivered to the customer by the end of this year.

Trulite Glass & Aluminum Solutions manufactures architectural aluminium products, insulated units, mirrors, tempered, laminated, and decorative glass from 26 locations in the US and Canada.

Glastronic anniversary

Glastronic, a subsidiary of the Lisec Group, celebrated its first anniversary and at the same time opened a 1,165 m² production hall.

Around 100 customers, suppliers and employees of the LiSEC Group took part in a celebratory event in Oroszlány, Hungary.

Perfect pour from O-I

O-I has designed a bottle that allows a more precise pouring of beer.

This is particularly important for premium products in the area of​​ craft and gourmet beers.

The unusual feature of the bottle is an asymmetrically shaped neck. On one side, the slender neck has a diagonal connection between bottle body and bottle opening.

Depending on the rotation and angle of the bottle, the pourer can influence the way the beer runs into the glass.

The Artesanal 500 bottle and MyPour concept was developed by O-I and is used by breweries in South America. O-I is currently investigating whether European brewers might be interested in using MyPour to create a point of difference for their own brands.

J

ames O’Callaghan’s fascination with glass has been honed over the past 20 years of working with the material. His area of expertise is in using glass as a load-bearing structure. While it is well known that glass is used as an envelope on buildings, it is less known that it can also be used as a load-bearing structure. Thanks to a design partnership with Apple, the agency that Mr O’Callaghan co-founded has helped create some of the software giant’s most iconic buildings – all made of glass. Some of the structures he has helped engineer are pictured in these pages and include the Apple Zorlu Glass Lantern in Istanbul, which was awarded the IStructE Supreme Award for Excellence in Structural Engineering in 2014.

The agency has also helped create the designs for the glass stairs, bridges, facades and other structural elements for Apple retail stores around the world.

In announcing the award the Phoenix committee highlighted Mr O’Callaghan’s contribution to advancing the application of structural glass in the built environment.

Mr O’Callaghan said: “It’s always a great surprise and a great pleasure to receive an award. I’m always still surprised when we as a practice win awards and are recognised for the work we have done. I hope that is an acknowledgement that we have put a lot of effort and work into moving the glass industry along as much as we can from a design perspective and an innovation perspective.”

He first discovered glass as a structural material after joining Dewhurst Macfarlane & Partners (DMP) in 1995.

The company’s founder and Mr O’Callaghan’s mentor, Tim Macfarlane, was an early pioneer of structural glass. According to Mr O’Callaghan, Mr Macfarlane’s took glass from something that participated in the structure to glass being the structure. “That was a big leap of faith,” stated Mr O’Callaghan. “He was discovering all the time through testing and research, there wasn’t an established framework to reference, it was about testing things and seeing at what point things broke. It was about using that iteratively to try and inform the design process.”

The company was involved in projects including Keats Grove, in Hampstead, London which used glass beams and columns for the first time and the Tokyo Forum subway station, which used larger scale cantilevering glass elements.

“It was all about the ways in which glass connected together. I was working with him at the time, participating and learning from him about what was important about the behaviour of glass.

“That’s where I was introduced to glass and that’s where I fell in love with the material and the idea of what you could do with it or its potential.

Apple In 2001 he was introduced to Steve Jobs. It led to the creation of a design partnership with Apple that has defined glass as a key element in the identity of the software giant’s stores.

Mr O’Callaghan said: “A lot of the work with Apple has been a key driver of innovation. We have been lucky enough to have a patron such as Apple, which was as fascinated in glass as much as we were. It was therefore prepared to fund the research necessary to make the buildings they have built as great as they are.

“Apple has a fastidious level of detail and an obsession with quality and that followed to all the work we did. It took everything that was seen as the norm and stretched those boundaries within the timeframe of any one project that we worked on.”

www.glass-international.com

Engineering In 2004 he co-founded the Eckersley O’Callaghan engineering practice, which offers a range of building and structural services. The practice has expanded to employ nearly 100 people and has offices in London, Paris, New York and San Francisco. Glass remains a key material to the practice.

“What we do is broad but the expertise we have in glass is something we have been honing for the last 20 years.

“There is a fascination with it as a material. Glass is unique in that it has this incredible combination of characteristics, its transparency, its purely elastic behaviour, which makes it behave in many ways a predictable manner structurally, but in an unpredictable manner in terms of how it breaks!

“Learning to deal with those characteristics – which are specific to glass and not to other materials – is where the fascination lies.

“Understanding those characteristics allows us to be more ambitious about how we use the glass

years

and I think that is what we have tried to do by understanding its behaviours and combined it in a structure to create more interesting, more complex and larger scale structures.”

The work he is most proud of includes, understandably, the partnership with Apple.

“My focus has always been on the detail of the connections of glass and the insert lamination concept which we developed for Apple, is something I’m proud of.”

Another career highlight has been influencing the façade industry to develop fabrication equipment to make much larger panels of glass.

In 2009/2010 the largest pieces of glass that could be laminated were roughly 8m. Mr O’Callaghan began working with Beijing North Glass (BNG) in China to increase the size of the glass to 14 metres. European glass fabricators were reluctant to participate in the project because they saw no commercial value in an item of glass 14 metres long. There are now examples of 14 metres sized glass throughout the world.

“We were convinced that if you did it, demonstrate it and build great projects with it, others would want to do it and sure enough that’s now the case.

“BNG were brave enough to take the step without any real insight into what the return would be.

They didn’t spend a lot of time analysing statistics and market evaluation models on whether the product will be successful, they just did it.

“If it doesn’t work it doesn’t work. It’s important to have that attitude for innovation.”

Brave While innovation remains key to Eckersley O’Callaghan, Mr O’Callaghan also recognises it requires clients who support the development of new ideas.

“You need someone who is prepared to be brave, they’re stepping into the unknown. Some of the elements of what you tell them you don’t know the answers to, so they have to feel secure that you’re going to get the right answer eventually but they Continued>>

Heinz-Glas reaps benefit of fifth line Heinz-Glas’ Piesau site has recently invested in a plant upgrade, which saw it unveil a fifth line. Here Heinz-Glas COO, Dr Jorge Utsch, explains how the expansion will benefit its customers.

www.glass-international.com

What is the Piesau plant’s role within Heinz-Glas? What is made there and what do you think is the most popular product?

The plant in Piesau has a very special role within the Heinz-Glas group because our company was founded there in 1622. It is our oldest site and will turn 400 years old in 2022. In terms of engineering, the Piesau site also offers some specialities.

We have a colour feeder, which is not a standard at every glass production site.

Additionally, we are also able to manufacture Post Consumer Recycling (PCR) glass in Piesau, considering our customers’ high demands and the look and feel of our products.

In Piesau we manufacture bottles and jars for the perfume and cosmetics industry.

In August 2017 we brought a fifth line into service, which can produce bigger bottles e.g. for the spirits market. The new line can produce single, double and triple gob and came into operation on August 18th. We will be able to produce an additional up to 400,000 articles per day.

� The site produces a variety of bottles

Can you give a brief history of the Piesau plant?

The glass factory in Piesau was founded in 1622 by Hans Heinz, who was a direct ancestor of the current owner. During the GDR leadership, the plant was a so-called ‘nationally-owned company’ and was taken over by the then

Carl-Aug.Heinz Glashüttenwerke company in Kleintettau. Since then a plant-wide upgrade work has been carried out; with on particular, a modern furnace fueled by natural gas.

How many glassmaking plants does the company have overall? How many furnaces and what is your daily production capacity?

We have five glass factories in Kleintettau and Piesau; Germany, in Dzialdowo; Poland, in Lima; Peru, and Kosamba; India, with seven furnaces in total and a daily tonnage of 428 tons.

What are the plant’s strengths?

We use modern production and testing machines, which enable us to meet the high requirements of product quality and produce effectively at the same time.

Furthermore, we are also able to produce more than 80 colour glass versions. The new line in Piesau is part of our short, mid and long term strategy to specialise our international plants.

Doing this we focus on the needs of our customers and market developments we see and expect.

Apart from that we focus on multifaceted complex decoration techniques such as frosting, single and multiple colour spraying, metallisation, lasering, gluing, pad printing and silkscreen printing.

Where are its main customers geographically? How many of the products are exported and what are the main countries that you export to?

Our most important markets are France and the USA. South America and Asia are gaining in importance. Our export rate is 80%. � The additional fifth line can produce larger bottles for the spirits market.

� Customers will benefit from 40 million more bottles and jars a year.

You have recently installed a new IS machine at your plant in Piesau. Why did you choose a GPS machine?

We have worked with GPS for many years. We appreciate their reliability and excellent customer service. Furthermore, the engineering of the machines has improved over the years and that’s why GPS was our first choice again.

Did any other investments take place at the plant at the same time?

The machine investment is part of a capacity enlargement in Piesau with additional investments regarding buildings and the construction of a completely new production line. We have still space for a new furnace. This gives us the opportunity for further investments in IS-machines, annealing lehrs or cold end inspection machines.

How will the customers benefit from the investments?

Due to the above-mentioned capacity enlargements, we can offer our customers approximately 40 million more bottles and jars per year. They are already scheduled which shows that the investments go hand in hand with our customers’ requirements.

How big is the plant?

Our premises in Piesau are 4,500 m² in size. The production area is 2,250 m². We now have 280 employees in Piesau and 30 of those are new thanks to the fifth line.

How would you like to see the company evolve in the next five years?

In five years we are turn 400 years, so our goal is to have a turnover of €1 million for every year of the company’s history.

For that reason, both the Heinz-Glas Group and the Piesau plant are working on specific plans to enlarge our capacities in order to meet our customers’ requirements and requests. �

We deliver the essential building blocks of glass: chemically pure silicon dioxide for uniformity, highly reactive sodas and alkalis to speed the melt, aluminas for strength and durability, and calcium and magnesium rich oxides for stability.

Processed specifically for the glass industry, each grade is designed to fuse quickly in the glassy phase to produce a homogenous batch.

Investigating the Thermal Homogeneity Index The Thermal Homogeneity Index is used as the absolute measure of forehearth performance, but there is not enough literature concerning the practical aspects of this type of measurement and the inaccuracies within the measurement. Juergen Groessler* aims to shed light on this subject.

T

he thermal homogeneity of forehearths is considered by most operators to be a benchmark for the efficiency of the forehearths. The so-called ‘thermal homogeneity index’ (THI) is a criterion for the acceptance of forehearths today. Of course, there are correlations between the THI and the

pack-to-melt rate of the production line, but there are very few (or no reliable) figures to prove this context.

Experience has shown that for the narrow-neck-press-blow process (NNPB) a thermal homogeneity of more than 92% is sufficient in most cases. Many glass producers demand guarantee values

of 96 – 98% in their tenders. Numerous examples show that the Sorg Forehearth series 340S and STF are reaching these values – even without additional equipment.

It should be kept in mind that the THI is measured in the forehearth in front of the spout entry. Then the glass reaches the production machine via a gob delivery system influenced by plunger, rotating tube and shears.

These influences are also important factors regarding glass homogeneity and the gob, but are no subject of this article.

A method of efficiency measurement is a basic requirement for the study and evaluation of any process and the operation of glass conditioning systems (working ends and forehearths) is no exception.

At the present time, temperature distribution across the channel crosssection is regarded as an adequate substitute, being both easy and cheap to measure.

The accepted method of measuring the temperature distribution involves the use of three triplex thermocouples. This arrangement provides a matrix of nine temperatures that cover a defined part of the cross section of the glass bath at the location of the measurement To allow easy comparison of various sets of readings the nine temperature values of a single data set are treated mathematically to give a value, which is normally quoted as a percentage value.

If all of the temperatures are exactly the same the formula will give a value of 100%.

Today this ‘percentage’ value – usually referred to as the Thermal Homogeneity Index (or THI) - is used as both a comparative and an absolute measure of forehearth performance, and there are many references to these values in the literature.

However, there is little information available concerning the practical aspects of this type of measurement, and in particular, on the various inaccuracies that are inherent in the measurement.

It is the object of the current treatise to shed some light on this neglected subject.

The calculation There are two methods of calculating the THI, and although all begin with the same basic data, they can produce quite different results. Method (1), is usually attributed to O-I and utilises the sum of the six horizontal differences between neighbouring values and the three largest vertical differences.

The divisor is the highest temperature found in the middle vertical set of readings.

� Fig 2. Location of thermocouples.

� Method 1: THI calculation attributed to O-I

� Method 2: THI calculation attributed to Emhart

Method (2), is often referred to as the Emhart version. This is very similar to the first, but in this case the vertical differences used are the top-tobottom differences at each of the three measurement locations. The divisor is defined as the centre temperature (middle triplex, middle temperature).

The different methods of calculation give differing results, and the extent of the difference can vary, depending on the actual temperature distribution.

As the two methods have no mathematical basis as percentage values, it is not possible to refer to any one of them as correct or incorrect. They are quite simply empirical values.

This point must be borne in mind whenever results are compared, as a comparison is only valid when the same method of calculation is used.

Studies from both companies show the central and bottom side glass have

greatest influence on the gob.

That is the reason why meanwhile O-I uses an adapted calculation method.

They only consider five measuring points of the nine-point-measuring method – indeed the three vertical in the middle and the two outer bottom temperatures.

The top side glass can have a significant effect on efficiency value but not on the bottle.

The measurement The actual temperature measurements that form the starting point of all the calculations are obviously important.

A close examination of the actual practical aspects of these measurements reveals surprisingly large potential errors.

Some of the largest sources of such errors are discussed below.

� Fig 6. Temperature distribution with favourable tolerances: THI = 97.4.

THI = 92.6.

The location of the measurement It is accepted that the three triplex thermocouples (Fig 2) are located as follows:

www.glass-international.com

One on the channel centre line One each side at a distance from the centre line of 33% of the actual channel width at the measurement location Moving the outside thermocouples towards the centre will almost always result in a reduction in the temperature differences and a consequent improvement in the THI value.

The three couples of the triplex element are usually arranged so that the top couple is 25mm below the glass bath surface, the centre one is at the middle of the glass bath and the lower one is 25mm above the channel bottom.

Reducing the distance between the top and bottom elements will almost always lead to better results.

The vertical spacing has a second important aspect. The height of the glass bath surface is a nominal value derived from the planning of the installation and this value will normally be used to design the triplex thermocouples.

In practice there is no guarantee that the glass bath surface is anywhere near the planned level.

It may be higher, in which case the top measuring point will be further from the surface, but in most practical cases the glass level towards the front of the

forehearth, where the measurement is made, will tend to be lower than nominal.

The situation is even more complex in that the glass level at the measuring point may change, depending on the pull on the forehearth.

The location of the measurement along the forehearth axis is within the glass industry not standardised at all.

The measurement should be made as near to the front end of the channel as is practically possible. However, the action of the rotating tube used in most feeder bowls causes a stagnant area against the channel wall on one side of the channel.

The glass in this area will always be colder than the flowing glass, and so this area would affect the measurement, although the phenomenon is completely independent of the forehearth.

To avoid an unwanted falsification of the measurement the location of the measurement is moved upstream to ensure that a thermocouple is out of the stagnant area. In Sorg forehearths the distance is approximately 400mm back from the reference line.

Positioning Once the location of the thermocouples has been decided there is still uncertainty about the exact position of the measuring points. Installing thermocouples on hot forehearths is not an exact science.

Practical experience has shown that the variation may be as much as ± 15mm

horizontally and ± 10mm vertically.

The side elements tend to be in areas in which there are temperature differences of several degrees within a short distance.

Analysis of a typical temperature distribution shows that the position tolerance may result in temperature measurement differences of more than ± 5°C.

Tolerance All thermocouples are subject to a certain tolerance. According to the European IEC 584-2 standard the commonly used type R and S thermocouples (13% and 10% rhodium respectively) have a permitted tolerance range of ± 1°C at 1200°C.

Ageing In the case of typical high temperature couples the ageing results mainly from migration of rhodium from one wire to the other. This depends on temperature and atmosphere to which the individual couple is subjected, and therefore the effect of ageing is not quantifiable.

Connecting cables and indicator Temperature results are displayed on some type of indicator that is connected to the thermocouple by compensating cable.

Compensating cables can also introduce an element of uncertainty into the measurement, especially in view of the Continued>>

fact that the actual thermocouple signal is small (a few millivolts). However, any effect on the temperature measurement is not quantifiable.

www.glass-international.com

Measurement inaccuracies Having demonstrated that there can be considerable inaccuracies in the measurement, and some of these are not even definable, it remains to determine what influence, if any, these uncertainties can have on the results. Two examples illustrate this.

In the first case we will assume a theoretical temperature distribution in which all nine temperatures are actually exactly the same. Of course, the THI calculation gives a value of 100. If we only consider the possible tolerance of the thermocouples themselves and the indicator on which the results are displayed each value may differ by ± 2 degrees from the correct value. If we then distribute the possible variation in the most unfavourable way, so that each individual value is now four different to all neighbouring values, as shown in Fig 3, the THI value drops to 96.7.

The second example has a more practical basis in that it is based on a typical temperature distribution as found on an operating forehearth. The basic data, shown in Fig 4, gives a THI value of 95.3.

As in the previous case the basic cumulative tolerance of the thermocouple and indicator is applied, but in addition a small displacement of the two outside thermocouples has been added. One has been ‘moved’ 8mm laterally, which changes all three temperatures by three degrees whilst the other has been ‘moved’ 5mm vertically, which leads to a one degree change in the three temperatures.

If all adjustments are made in the most unfavourable way, the resulting temperatures are shown in Fig 5, and the THI is reduced to 92.6, a drop of almost three points.

Alternatively, if the resulting alterations are all favourable, the temperatures shown in Fig 6 would be displayed and the THI rises to 97.4, an increase of over two points. It is clear that the two examples detailed here are just that – examples, but they are representative enough to illustrate the following points. � The THI calculations are based on measurements that harbour inherent inaccuracies � The basic inaccuracies in the measurement hardware means that any

value of the THI over 97 is mathematically uncertain and cannot be relied upon � Further inaccuracies relating to the exact location of the measuring points introduce additional uncertainty into the THI calculations. This additional level of doubt can easily exceed ± two points. � Some sources of inaccuracies are definitely present but not quantifiable. These include the ageing of thermocouples, changes in actual glass level and low-level thermocouple signal degradation.

These results show that the THI value is only really of limited value in the evaluation of forehearth operation.

Factors of influence Mostly independent from design and operation of a forehearth, the thermal homogeneity can be slightly improved by installing stirrers, with paddle stirrers being more effective than spiral stirrers.

Due to the wear of the stirrers the positive effect is not constant. Depending on the values, the operator has to exchange the stirrers precautionary. Moreover, the improvement cannot be implemented targeted, as except for the rotation speed no variable factors exist in practice.

For coloured glass, electrodes are the most effective method for improving the thermal homogeneity. With these, targeted heating is possible at the sides or in the lower section of the glass bath.

Provided the heating system has been designed correctly, this system gives high flexibility.

Moreover the advantage of electrical heating is the reproducibility of the settings. In Sorg control systems the auxiliary electric heating system is adjusted optimally to the temperature distribution with a special control unit.

The well-known ESIII expert system also aims at a permanent THI optimisation.

Not to be forgotten is the individual adjustment of the production machines in dependence of the articles to be produced, especially in multiple gob operation.

When operating triple- or quadruplegob, often all forehearth side temperatures are set higher than the middle temperatures. This means that for this type of production it is accepted that the gob form/distribution is more important than the achievable THI value. With a THI value of 98%, the THI dropped to 96,7% if all side temperatures are adjusted 6°C hotter.

Conclusion This article is to show that there is the requirement to achieve a THI of 98%, but that this is not absolutely necessary for successful production.

One may not forget that measuring inaccuracies and module inaccuracies exist. Values of 98% are achievable, but it must be clear that manpower or an intelligent control system is required to achieve these values constantly.

Comparison of results of THI calculations under various operating conditions on one forehearth are probably acceptable, because the use of the same measurement arrangement effectively neutralises some of the error sources, although even this type of comparison must be treated with caution.

The inherent errors in the measurement system effectively preclude its use to provide a meaningful comparison of the operation of different forehearths.

A further important factor that also has an impact on stable production is the stability of forehearth conditions. Stable temperatures at a certain level may be of more value to the production than an attempt to optimise the THI value that can lead to a prolonged period of instability.

The THI calculation does not address the stability question at all.

Based on practical data there are numerous examples for forehearths which although they have a relatively poor thermal homogeneity, ensure excellent production.

In view of the foregoing it is not surprising to find that there appear to be no reports of a direct connection between THI value and percentage pack. Although the THI value can often give a clear indication of how the production will run on a given line, the so-called 85/95 syndrome is well known.

This refers to a line on which the THI value is only 85% (a poor value) but the production still runs at 95% pack-to-melt.

Alternatively, the THI value may reach 95% (a very good value) but the pack-tomelt does not exceed 85%.

There are doubtless many potential causes of the 85/95 syndrome, and blatant inaccuracies in the THI measurement is definitely one of them. �

GPS

Based in Essen, Germany, Glasproduktions-Service GmbH (GPS) is a leading developer and supplier of IS machines and modules for the container glass manufacturing industry.

After more than 90 years as part of Verallia Deutschland AG, GPS became an independent entity in 2016, a move that brought the specialist German company both, commercial and technological success in its very first year. Six new patents, substantial revenue growth and the recruitment of additional highly qualified personnel – GPS had an exceptional year in 2016 and the upward trend is continuing in 2017. This success is no coincidence, and GPS’s international customer base today benefits from the IS machine specialist’s many years of expertise, as well as the reliability of a traditional enterprise coupled with the innovativeness and flexibility of a young company. This has been well received by customers and GPS products are more in demand than ever before.

A reliable partner with traditional roots As the former subsidiary of a major container glass manufacturing company, GPS has almost 100 years of experience, practical know-how and unique sector insights, so it knows what international glass manufacturers want and need. As a result, the IS machine manufacturer has a stable market position and an unparalleled insider perspective.

This knowledge about its customers, their requirements and the challenges they face in their daily business makes GPS unique. Such profound, experience-based competence is also advantageous in the development of special products. The entire GPS portfolio – from IS machines and modules to servo mechanisms, feeders and cross-conveyors to control and drive technology – reflects this knowledge advantage.

Batch plant

From raw material unloading to batch charging

� Fig 1. A typical batch plant as an “in-line” plant with 14 different raw materials.

Zippe’s Volker Maier* takes us on the technical journey that leads to the production of high quality glass.

Only when these parameters can be fulfilled can a fully-automatic and up-todate glass production work successfully.

The design of a batch plant will be influenced by various parameters. Main criterias include the required melting capacity, the number of raw materials, as well as their delivery.

Whether the construction type is a

‘tower or in-line plant’, whether silos are made of steel or concrete, or whether operation is fully-or partly automatic as well as the location and integration of the batch plant, all of these factors will be discussed together with the customer during the planning phase. Zippe always finds the most optimal solution for customer wishes!

Tower plant When referring to a so-called ‘tower plant’, simple versions for smaller melting capacities and a small amount of raw materials are meant. For this solution, the raw material silos and the scales are placed centrally around the mixer.

The discharge of the weighed-in raw materials from the scales into the mixer, is effected by gravity and without any further conveying technology. This solution is restricted by the quantity and size of the raw material silos.

If a greater amount of raw material storage is used and a high capacity is required, or furthermore numerous furnaces are fed with different recipes, then in these cases batch plants will be

designed as ‘in-line’ plants (Fig 1).

For in-line plants individual scales are placed underneath the silos. All of the scales discharge onto a centrally placed conveying belt which will transport all of the weighed raw materials into one or more mixer.

Fully automatic batch production The raw materials needed for glass production will be delivered by different means of transport and in different transport quantities. The smallest quantity can, for example, be 25kg paper bags, the biggest quantity can even be by sea freight up to 10,000 tons.

Transportation can be effected by truck, train, or as described above, by water route.

The raw material discharges can principally be divided into three main categories: � mechanical discharge � pneumatic discharge � manual discharge (of small components) Continued>>

or a glass factory, one of the most important steps in the glass melting process is the production of melting batch. An efficient batch production plays a key role when producing high quality glass!

Excellent raw materials, effective dosing and weighing installations as well as mixing aggregates are needed to produce high-quality glass. This melting material consists of several raw materials as well as of cullet, and should be made available as follows: � at the right time � in the desired quantity � in the perfect composition and homogeneity � available on demand 24 hours a day

automatic check-weighing.

For the main components of batch production, the two continuously working discharge types (mechanical and pneumatic) are mostly implemented, the reason being that a higher discharge capacity can be achieved.

The discharge time (holding time) of vehicles and the costs that arise with them have become more significant.

For mechanical discharge (Fig 2), the delivered bulk goods are usually delivered by trucks or train wagons and then discharged into a hopper. After the discharge of the raw materials into the feeding hopper, a fully automatic batch production follows from the feeding of the silos, including the weighing up to the furnace feeding.

Figure 2 shows a typical discharge process with a vibratory tray feeder, a bucket elevator and different conveying belts in diverse raw material silos.

More customers favour iron-free batch production, especially for solar glass or similar uses. For this reason, magnetic separators and non-ferrous detection and removal devices have to be integrated.

As shown in the illustration, it can be effected for silo feeding as well as for the batch transport.

Another important aspect for the planning of a modern batch plant is the design and arrangement of the silos. The product-adequate design of a silo is an essential step for maintaining the quality of bulk goods while in storage. The arrangement of the silo has to be adjusted to the individual storage problem, and the specific product characteristics of the individual flow material has to be

considered. Storage silos for raw materials will normally be manufactured of mild steel or concrete. In special cases, it is also possible to manufacture silos of stainless steel or with a special plastic lining.

Generally, steel silos are constructed in a round version with bolted or welded smooth walls. For silos made of concrete, it is possible to choose a round or rectangular cross-section. They are mostly constructed in a slip form design. For the planning of the silos and the discharge cone, attention has to be paid to when the silo is discharged, so that a mass flow is guaranteed and a segregation discharge is prevented. Bridging and core flow are to be avoided as well (Fig 3).

According to DIN 1055, the minimal hopper inclination can be determined for every raw material. Since the material characteristics are often not clearly known

during the design phase, the experience of the design company is highly relevant.

Meanwhile, Zippe has the experience of 600 newly planned batch plants.

Weighing it up To achieve satisfactory dosing and weighing of bulk goods, a constant product discharge out of the storage silos is a pre-requisite.

This can either be achieved by the above mentioned lay-out of the silo cone, or by the use of discharge aids. Discharge aids are the devices that serve to maintain the material flow out of the silo and to improve the flow properties.

These discharge aids can either be vibratory bin activators, air cannons or silo cone vibrators.

www.glass-international.com

In modern batch plants the main raw materials are mostly weighed by container scales (Fig 4). According to customer wishes or requests, this will be accomplished by the weighing-in or weighing-out principle.

For the weighing-in technology, more components can be weighed-in a container scale after another.

The dosing of individual raw materials is effected according to the conveying material, transportation distance, or flow behaviour by means of vibratory trays, screw conveyors, or belt conveyors. For smaller components this can be carried out by fine metering screw conveyors with a high accuracy.

Further important aspects for the planning of a modern batch plant are: � Filling level control measurements � Moisture measurements, adjustment of the water content in the batch � Mixing plant, batch homogeneity, water- and steam addition � Minimizing dust by the use of filter technologies A large part of the melted material consists of cullet. Over centuries, the share of cullet only consisted of factory cullet from own production.

In recent years, the share of external cullet addition has increased particularly for container glass production. Therefore, it is not unusual that within 60 and 85% of cullet is discharged into the melting furnace today.

Due to the high flexibility when adding cullet, more weighing belt feeders are implemented instead of container scales.

By using weighing belt feeders (Fig 5)

flexible charge sizes can be achieved with a similar weighing accuracy.

Less construction height is needed and less abrasion is also apparent. This is an advantage, particularly for low iron glass production.

Internal and external cullet can be weighed at the same time or separately.

Storing external cullet can either be effected inside the batch plant or in a single silo near the furnace. Cullet is mostly added on top of the mixed batch just like a sandwich. Mixed batch and cullet are transported from the mixer to the furnace pre-silo by means of belt conveyors or bucket elevators. Depending on the furnace size, there is additional distribution into two furnace pre-silos.

For the planning of the furnace presilos, the integration of a possible batchand cullet preheater as well as the feeding of the batch charger should be attended to. After the mixer, the batch and cullet preheater (Fig 6) will heat the batch temperature from ambient temperatures up to 300°C by the use of waste gases from the furnace.

Based on experience, 10-15% of the melting energy consumption can therefore be saved in. It is important to emphasise the overall material selection, the excellent stability of aggregates while exposed to high temperatures, and the dust-free conveying and charging into the melting furnace.

When adding batch and cullet to the furnace, there are different types of batch chargers available.

This depends on the type of furnace, the Doghouse design, furnace capacity and on the glass type. In case preheated

batch is used, it is necessary to implement a batch charger with a closed dog house so that dust can be minimised.

Batch production is strictly monitored and protocolled around the clock, because only then reproducible results can be achieved. A precondition for this is a fully electronic process control made of the most modern construction type. Weighing electronics, especially developed for the glass industry, enable easy handling. Principally, this is also possible with tablet computers. Zippe’s weighing controllers are generally an integrated part of the control system.

On demand, self-sufficient weighing systems can be implemented as well.

These can then replace old controls such as the ones from external manufacturers.

Zippe Industrieanlagen is a Siemens PCS7–solution partner and has already delivered more than 20 batch plants with a PCS7 system. Zippe is also able to implement the PWA concept without any limitations.

Finally, the arrangement of the high tech systems as well as the entire planning and coordination signify an extremely complex challenge that can be solved ideally with the right know-how and corresponding technology.

To fulfill individual customer wishes and requests, the diverse criteria and conditions indicated above have to be adhered to so that excellent plant results can be achieved. �

lass melting processes require precise weighing and mixing of each batch ingredient fed to the furnace to produce quality product consistently. However, once mixed and available for the furnace, there are a number of potential events that can degrade the uniformity of the mixture and result in variations over time.

These challenges are understood, and range from poor bin flow to segregation upon charging. The influence of a screw design, if utilised as part of the furnace feed system as a charger or for batch wetting, might be overlooked.

Some of these same issues can occur within the batch house, where screw feeders are often used.

Screw feed systems are often used in the glass industry because they are enclosed and are reasonably resistant to abrasive wear. They provide containment for dusty and hazardous materials and can offer good discharge rate. Screw feeders are also versatile and can occupy less headroom than other types of feeders.

The basic requirement for a successful screw feed system is to meter the bulk material in a reliable, controlled manner at the desired rate. This requires first that flow problems such as arching and ratholing must be avoided in the bin or hopper directly above the screw. For a furnace feed system these requirements

have additional importance. The loss of batch flow to the furnace is a concern, and ratholing can result in stagnant zones that in turn bring about caking and clumping due to the presence of ambient heat.

Further, during the filling of a furnace feed bin the mixed batch can segregate, often by particle size but density and other factors can play a role as well. Areas that are stagnant during discharge can concentrate off-spec material, resulting in composition variations in the feed to the furnace as the bin level changes and the stagnant material is recovered. To ensure reliable performance, a mass flow pattern in the bin or hopper is required.

Achieving mass flow requires that hopper sections be smooth and steep enough to provide flow along the walls, while the hopper outlet must be sized large enough to prevent arching and to achieve the required flow rate. These requirements can be determined through bench-scale testing of the material being handled. The use of hardened wall materials can overcome abrasive wear concerns in such systems. [1]

Screw features Designing the hopper above a screw feeder for reliable flow is necessary but not sufficient to ensure success. For a screw feed system to perform reliably, the material being fed must enter the spaces

between the screw flights over the entire hopper outlet. A common challenge is that the material flows at the required rate, but the velocity is much higher over the back end of the screw than elsewhere along its inlet length. This behaviour can result in material flow problems of segregation and ratholing, even if the hopper feeding it was designed for mass flow. Therefore, features of the feeder itself have a strong influence on the flow performance that occurs in the bin or hopper above the screw. [2] When the screw is not designed to pull material uniformly over its entire inlet length, stagnant zones in the hopper above will develop. Consider Fig 2. The constant pitch and shaft diameter over the screw length results in flow at the first point of contact (represented by the lighter coloured material and arrow), which is at the back of the inlet. Compounding the problem is that this arrangement includes extra flights before the outlet starts, which enforces even stronger flow at the back of the screw as material rushes into the housing to fill these spaces. Once the first flight is filled, the screw cannot accept any more material over its inlet length, and is simply conveying forward what has already been fed to it (medium coloured material), leaving stagnant Continued>>

material around the flow channel in the hopper above (darker coloured material).

Although details are not shown in the image, feed screws of this type might utilise cast, replaceable flight sections installed over a reusable shaft. This is a machine design approach to reduce the maintenance costs associated with abrasive wear of flight surfaces as compared to a fabricated screw. This arrangement can support the life of the equipment over a furnace campaign, but does not provide the needed increase of capacity in the direction of feed.

To ensure reliable flow in a bin or hopper above a screw feeder and maintain batch uniformity, several rules must be followed: � The screw size (flight outer diameter) must be constant within the inlet area, and equal to the inlet width; � A U-trough must be used, and not a V-shaped trough which would promote stagnant material along the trough sides that might disrupt material flow above; � The flights must not start before the back of the inlet; � Since feed screws generally run full, they must only be supported by end bearings and not hangar bearings; � Most importantly, the flights must be arranged such that the full inlet area is active (that is, material is flowing into the screw over the entire hopper outlet); this often requires an increase in pitch for each flight section within the inlet area in the direction of feed, and can also be accomplished by using a tapered shaft.

ANNEALING LEHRS

HOT-END COATING

A feed screw designed with a uniform increase in capacity along its length is required to activate the entire hopper outlet.

One method of achieving this goal is to increase the pitch in the direction of feed within the inlet area, (Fig 3). This approach can still be implemented when cast flight sections are used, although it requires the use of more than one casting.

When the severity of the associated flow problems is weighed against the cost of procuring and maintaining a small number of different cast sections, the investment is likely well justified.

For fabricated screws, which might be used in a batch house, a tapered shaft feature can be utilised in addition to an increasing pitch, to provide an increase of capacity over a longer inlet area, (Fig 1).

Conclusion Screw feeder design can have a significant effect on the flow performance of a hopper or bin above. Negative effects of poor design range from flow stoppages and buildup to batch variation over time due to segregation. If designed to ensure a fully active inlet area, a screw feeder can contribute to reliable solids flow of the entire system. Features of a screw design that will activate the entire hopper outlet include a varying flight pitch and/or a conical shaft within the inlet area, as well as avoiding extra flights behind the start of the inlet. These features can be implemented as part of a cast flight system with the use of some additional castings, as well as within fabricated screws. �

Ratchaburi: A glass plant serving southern Thailand

� 3D plan of the Ratchaburi plant.

Bangkok Glass business group, BG Container Glass (BGC) is building a 320 tonnes per day glass factory at Ratchaburi, Thailand which is due to be operational in late 2018. The company’s President, Pavin Bhirom Bhakdi, discusses the venture and how it will benefit southern Thailand in particular.

Why did you to decide to build a new glass factory at this particular site?

www.glass-international.com

Because it is logistically feasible to transport our products to the southern part of Thailand and also to many customers around the area.

What benefits will the new factory bring to both you and your customers?

We will be able to satisfy the demand of customers in that area/zone, but most importantly, to lower transportation costs.

Who will be the plant’s main customers and what products will be made there?

Flint colour products, concentrating on the food and beverage segments.

Will the Ratchaburi plant export to other surrounding countries in the region or just for domestic use?

Just domestic use.

Can you describe the process of what will happen between now and the start of operations in 2018 (i.e is there a schedule of when certain equipment will be in place?)

This plant was actually constructed back in 2015, but mainly warehouses and parts of the building was completed, so once the project was stopped for a year, we will have another 80% of the remaining to be completed. This is the reason why we could open it quicker than we expected in 2018. Therefore, we should be heating it up by the middle of 2018.

What are the most important factors you consider when deciding upon your production equipment suppliers for this plant (i.e cost, reliability etc)?

First of all, we want to build a glass plant with a maximum flexibility. That is why we would like to build 320 tons per day plus a booster of 240 tons per day with five production lines to satisfy customers from small to large bottles with the least human resources as possible and bring in more automation to the plant.

as a holding company. We are expanding into other types of glass products, therefore, which each one being a business unit we can manage each of them more efficiently.

Are you able to give an indication of the Thai container glass market at the moment?

Is the market expected to continue its growth?

Glass manufacturing in Thailand is only oligopoly type of business dominated by a small number of companies. However, there is huge room to expand. Currently, we are the first glass manufacturing company in Thailand to introduce glass products across the board.

We still see a big growth ahead, as the assumption of food and beverage still has room to penetrate in the domestic market. At the same time, growth of food and beverage in our neighbouring countries are still increasing in a rapid rate.

Can you tell me a few more details about the plant? www.glass-international.com

The size of Ratchaburi plant is 249,000 sq. m. with 400 staff. The lines are both double and triple gobs.

How long you have been with the company?

I’ve worked with BG for about 20 years. Working with people in this business is like a family-typed environment. I have been fascinated with glass products since I was a student, so it was no surprise for me to join a company that specialises in glass. I am very lucky to work with a product I have loved to do at the first place. That makes me a natural and passionate glassman. �

Hot end coating

A hood for hot-end coating Arkema has developed a new range for hot and cold end coating.

CertinAdvance answers the glass container sector’s needs by improving coating quality and production efficiency.

www.glass-international.com

C

ertin Clear is the hot-end coating part of the CertinAdvance range.

It consists of a new hood called ‘T-hood’ associated with the well-known Certincoat TC100. According to the company, this hood offers an easy-toreach homogenous coating on the bottles.

The T-hood is, like the Certincoat type C hood range, also designed to apply a tin oxide layer using a chemical vapor deposition (CVD) process and to coat glass containers at different production speeds.

This hood suits a variety of production lines. A standard heating element is installed to ensure fast turnaround following a job change.

Arkema’s T-hood (pictured) patented technology has several innovations.

Arkema’s R&D team developed a complete new layout, taking care of inner- and T-loop turbulent air circulation inside the hood.

It is combined with a laminar airflow at the finish and outlet of the hood. This solution leads to higher productivity and better quality.

It reduces emissions and increases HEC homogeneity on the glass containers.

Moreover a constant temperature inside the hood, due to T-hood higher cooling capacity that comes from a new chicane, combined with the PLC-controlled system, helps to further improve the coating homogeneity.

Arkema’s distance e-monitoring system allows real time control and to visualise parameters such as bottle count and temperatures from distance.

This gives the possibility to follow up production parameters from outside the production building. It can also make online support from the Arkema technical service team more rapidly able to answer any problem that could occur.

This new T-hood brings many

advantages to perform the hot end coating treatment.

Thanks to T-hood technology, reduced and easier cleaning leads to less maintenance and improved productivity.

Glass profile: SGT president

SGT President focuses on education Bill Brookes was elected President of the UK’s Society of Glass Technology in May. He told Greg Morris how he wants to ensure the Society meets the practical needs of industrial engineers and of those in academia and research.

T

he Society of Glass Technolgy (SGT) is close to Bill Brookes’ heart. He joined the society as a student in 1954 and it has been a part of his life since.

When he was elected President back at the start of the summer he felt extremely privileged and honoured. He has spent his career in glass, both in industry and in academia, after graduating from Sheffield University in the 1950s.

Apart from the occasional foray as a site or a production manager, his job title has always been that of an engineer. “The solving of engineering problems has been my life,” he said. But he has also always been interested in the training of young engineers, technicians and craftsman. He is a firm believer in education, something that was the ethos of the SGT’s founder, Dr W. E. S. Turner.

“Education was the bedrock of Turner’s legacy.

He was a great educationalist of not only the shop floor but people higher up in the board rooms.”

In his role as President he would like to ensure the SGT meets the needs of both practical engineers in the industry, as well as those who teach in academia.

“There is a balance between the necessity for the practical engineers and there is a necessity for the academics, such as those who teach and research.

Those are the areas I would like to focus on.

“We have to train our people. There is a chronic shortage of world-class engineers in the UK. Yes, we have a number of them coming along but we have woken up rather late and we are running like mad to try and catch up.

“The role of the SGT is to facilitate the interaction between academia and the commercial and practical side of the business.

“Things are more stable in the glass industry now after some turbulent years and I sense there is an opportunity for us to do the sort of things that we need to do to facilitate the interchange of knowledge and ideas to put the UK back on the map.

“We have good engineers, we know that, but there are not enough of them.

“I feel the relevance of engineers is once more coming to the fore and they are coming back again.

I feel the UK glass industry is entering a period of greater stability and there are opportunities for the

glass industry to improve itself and for it to use all the other things that are available to it in order to facilitate its improvement.

“In the past the glass industry itself has said we don’t need these people. But now it has woken up to the fact it does need these people.

“That’s where I feel the SGT has to play its part, to get itself around the glass manufacturers and, if you like, pedal its wares.”

Mr Brookes approved of the recently announced £20 million Glass Futures not-for-profit project set to be based in Rotherham, UK. The centre is backed by several glassmakers and technology suppliers. These include Owens-Illinois (O-I), Guardian Glass, Encirc, Siemens and Teco as well as academic institutions such as Leeds University and Sheffield Hallam University. The project is set to come on stream in late 2018.

Mr Brookes said: “Glass Futures is a very positive step forward. The SGT supports the prime movers in that organisation and will continue to support Glass Futures. These are people who are trying to change things, they are trying to provide facilities, Continued>>

it is providing facilitation in an area key to the SGT. It all comes back to education.

“In my opinion the area we have fallen down on is that we have not trained the people on the shop floor sufficiently enough, and we have not inspired and retained the best engineering minds in the higher echelons of engineering.”

Mr Brookes believes that glass and the UK glass industry does have a bright future. He hopes more people will be encouraged to join the industry in future years.

“Glass is a unique material that has been with us for 5000 years and will be with us for a lot longer.

I don’t actually envisage a world without glass, because it is used for so many applications today, some of which people may not realise.

“The glass industry in the UK is not dead and is slowly picking itself back up again. Glass can provide a good, and in particular, a satisfying career to thousands of people.”

www.glass-international.com

Professional career His love of the material began before university in 1950, when, alongside his father, he developed an interest in astronomy. Materials were hard to come by so the best way to get a telescope was to make it yourself. Mr Brookes read books about lenses and microscopes, which is where he became first acquainted with glass and its properties.

“If you had the necessary skills in turning and milling for example you could make virtually any optical instrument that you put your mind to. We made telescopes and microscopes and we needed to make the accessories that go with those, such as eye-pieces. They were not as well finished as, say, the Zeiss products but they were sufficiently good to do the job at the time.”

His father, a textile engineer, encouraged him to become an engineer, but not in textiles because he felt the industry was in decline. So after graduation, Mr Brookes began his career in glass.

“I’ve not been involved in what might be termed mainstream glass technology – I have only ever melted 2kg of glass in my entire career – but my career has involved glass in all its ramifications and forms. It has taken me into so many interesting and different areas.”

Much of his career was spent in the north east of England and in Scotland. He worked for companies that made television tubes, catho ray tubes, image tubes and radio valves. His career spanned the transformation of the television, from a hand blown cathode grade tube, to a pressed cathode grade tub, to a flat one and then the flat screen.

As those products developed, so did the glass.

Objects that were originally 40cm in diameter could be blown, but as they evolved into three feet across they had to be made by other means, usually pressed.

“The glass always gave interesting problems because of the stresses involved. People always wanted them to be bigger, better and of a higher

In 1916, Dr W.E.S. Turner, a chemistry lecturer at Sheffield University, UK, recognised the importance of drawing together, in one organisation, the various groups of people interested in glass. So, he formed the SGT. It was inaugurated at a meeting in the University of Sheffield, on Thursday November 18th 1916. Its object was defined as the general advancement of the various branches of glass technology by the association of persons interested in glass and glassware: the reading and discussion of papers; the publication of scientific information on glass technology; and the formation of a library and museum.

From this beginning the Society has responded to the needs of industry and academia, and remains a model for other glass societies. The Society continues to grow in stature with members in more than 50 countries.

Personality profile: Sheppee MD

A Managing Director with Sheppee i Simon Holmes was appointed Managing Director of UK ware handling specialist Sheppee on March 1. He has been associated with the company for 22 years and, on the six-month anniversary of his appointment he tells Greg Morris he has enjoyed a rollercoaster ride in the intervening years.

hen Simon Holmes walked through the door on his first day in charge of Sheppee recently he had a tear in his eye. He had been associated with the ware handling company for 22 years, joining the group as an 18-year-old apprentice and working his way up via a number of production and commercial roles.

Sheppee is in his blood and he has nothing but fond memories of his time as first an apprentice and then a fully-fledged member of staff.

“I am emotionally proud, it’s been a rollercoaster ride for me. I’ve worked here man and boy, I started my apprenticeship here 22 years ago, so it is an emotional achievement for me.

“I’ve always seen Sheppee as the place I was brought up. I have very fond memories of my

upbringing here as an apprentice, it was the company that has brought me on, it has seen something in me that worked.”

But it hasn’t always been plain sailing. The roller coaster ride has seen him twice leave the company – once on his own terms, the other more acrimoniously.

Enthusiasm For now though, Mr Holmes wants to get on with the job of managing Sheppee. He was appointed MD on March 1 this year, knows the company inside out and has plenty of ideas for the company.

“My personal attributes are the enthusiasm for the role. I also love quality. I’ve got the drive

� Sheppee is based in Elvington near York in the UK.

� Simon is keen to develop not only the company but people at Sheppee as well.

to keep moving the company forward, to keep redeveloping the equipment and also developing my colleagues here.

“Sheppee likes to be perceived by the market as the specialists at ware handling, in the appraisal, design, manufacture and support through ware transfers, lehr loaders, pushbars and cross conveyors.

“I’m massive on development, customers turn to us for the future and for developing products.

We brought out the dual belt system with the VFT at glasstec last year and we’ve got some huge development projects on the drawing board right now.

“You can’t rest on your laurels with your existing product portfolio.”

The company has what is known as a project hopper where development engineers and management will meet and swap ideas. Mr Holmes, with his experience in engineering and sales, can see things from both points of view.

“My focus is obviously on developing the business and developing new equipment but the security and well-being of all the people here is also of major importance to me.

“I believe that if you look after your people they will look after your company. I’m huge on that.”

Early years It is a far cry from July 1995 when, on the day of his 18th birthday he was interviewed for the role as apprentice.

His stints in production as assistant installation engineer and production engineer included work in mechanical assembly, learning about limits, fits and tolerances as well as building new equipment.

He also worked in the machine shop, which

involved drilling, grinding, welding, and a stint in the inspection department.

But when he saw a role advertised for Technical Sales Engineer he decided the vacancy offered more opportunities for travel. The move from production to sales has also helped give him a more rounded view of the company.

will meet and swap ideas.

Personality profile: Sheppee MD

I feel comfortable having discussions at any different level and in any department in Sheppee.”

In 2004 the time was right for a move and he was hired by US lehr manufacturer E W Bowman.

After four fruitful years, where he was based in Graphoidal in the UK, he was approached to be part of a management buyout of Sheppee in 2008.

The next few years though proved to be the lowest point of Mr Holmes’ career with Sheppee.

The market crashed shortly after the buyout and orders started to dry up. The banks were putting pressure on the company to repay its debts. This coincided with the passing of his mother and the rise of a rare auto-immune illness which, in his words, made him look like the horror character Freddy Krueger.

The illness is thought to have been triggered by an insect bite during a trip to Asia, although the stress of his professional and personal life at the time didn’t help.

The autoimmune illness is a skin complaint that caused the equivalent of 60% burns to his body. It lasted for three years before being diagnosed. He still bears the scars on his skin today.

“Without a shadow of a doubt, it was the lowest point of my career. I have a photo of myself from that period, and if I am ever having a rough day now, I look at one of the pictures and realise nothing is as bad as that.”

The combination of illness and the market decline meant he had to leave Sheppee.

www.glass-international.com

Recovery The time away from work put the fire back in his belly. The illness was identified by a new doctor at his hospital in the UK and Mr Holmes began a course of specialist treatment. It still took a year to flush out the steroids and illness from his body.

“I was very lucky because my wife rode through it all with me. During an illness such as that you have to consider your wife and family because it was hard on them too.”

While out of work Mr Holmes received a phone call from Rondot group CEO Louis Rondot, about forming a satellite company in the UK called RGB. RGB would represent Rondot and Graphoidal products in the UK. Mr Holmes took up the offer and RGB went from strength to strength.

� The company has some huge development projects on the drawing board right now.

“You can’t rest on your laurels with your existing product

”

portfolio

Then, in July 2014, Sheppee was purchased by the Rondot Group and Mr Holmes offered to assist with the integration along with the relocation of RGB into Sheppee’s premises, in York, UK, alongside its 44 staff.

Mr Holmes would assist Managing Director Mark Johnston who was combining his role at Graphoidal.

“I was really pleased to come back because Sheppee is a great brand and a well-managed company. You visit some factories in the world and they will say they have Sheppee ware transfers, even if they’re not. The ware transfers have become generic.”

Late last year, with the Sheppee team gelling well and the future of RGB looking secure, it was decided Mr Holmes would take over as MD, while Mr Johnston would focus on Graphoidal.

“It all came together nicely and it felt like the right time. I couldn’t have asked for a nicer management and director team around me, some of whom I have known for more than for 20 years.”

Mr Holmes lists Louis Rondot and Mark Johnston as his biggest influencers, alongside Dave Ulmer, formerly of E W Bowman and now of Sorg, as well as Lincoln Brown, formerly of Graphoidal and now of Pro-Sight Vision.

In five to 10 years time he hopes to see Sheppee still with a well-recognised portfolio, in front of the game using even more modern techniques and technology.

There are thoughts about moving into the tableware market as well as moving into larger premises, Whatever the future, Mr Holmes plans to be with Sheppee for a while longer.

“I’m drawn to the company and I’m drawn to the glass industry. You’ve got to want to come to work and you’ve got to enjoy your job. Here at Sheppee that is something I’ve done on and off for 22 years.” �

History

Prof. John Parker

Polarised views I

remember my school physics teacher explaining why a stick partially immersed in water appeared to be bent and a swimming pool was actually deeper than it looked.

This was my introduction to refractive index, but back in 1669 Erasmus Bartholin had observed something even stranger.

Objects viewed through large Iceland Spar crystals (calcite, CaCO3) gave a double image, and one image circled around the other when the crystal was rotated.

A century later, French physicist Etienne Malus observed that one of these images sometimes disappeared if the light had already passed through another calcite crystal. Eventually this led to the concept of polarisation, where light is understood as an electric field vibrating perpendicular to its path. The plane containing this vibration and the travel direction defines its polarisation.

The organisation of atoms in crystals, particularly any asymmetry, can affect light polarised in dissimilar directions differently. For example in calcite all the planar triangular carbonate groups lie parallel and result in a large difference in refractive index for light with parallel and perpendicular polarisations, an effect called birefringence. Glass though should be isotropic i.e. affect light equally whatever its polarisation but this is not so if stresses are present. Tension separates the atoms, decreasing proportionately refractive index for light polarised in the same direction; compressive stresses increase it. Now stresses can be complex but at points along the light path can always be resolved into two perpendicular components, which may be tensile or compressive and have different magnitudes. Propagating light splits into rays polarised along these two principal directions, one travelling faster (lower r.i.), the other slower. They become out of step by an amount termed retardation, which depends on the refractive index changes, and gives a way to assess stress.

Measurement of retardation uses an optical set-up which recombines the two rays on exit from the glass so that they interfere. Zero retardation results in destructive interference and gives ‘black’. Path differences of one, two wavelengths do the same but retardations of half, one and a half wavelengths allow strong transmission. Usually white light containing all the spectral colours is used. Each colour gives the same dark/ bright/dark sequence but the dark bands correspond to different retardations so when all wavelengths are combined coloured fringes result. However for weakly stressed glass viewed in white light, black (zero stress) or a difficult-toquantify shade of grey is seen. Tension and compression give the same colour and so are indistinguishable. So a crystal plate of defined thickness is inserted into the optics to add a whole wavelength of retardation (for yellow light) and shift to a more sensitive part of the colour sequence. Tension and compression also give different colours because the retardations either add or subtract from that of the standard plate.

While the instrument produces a defined colour sequence according to the stress level quantitative measurement is less easy. Standards have been created though using thin glass discs, pre-stressed in a furnace in a standard way by cooling under pre-defined conditions. Actual samples are compared with the colours seen at the edge of 1, 2, 3 … superimposed strain discs.

More sophisticated instruments such as the Berek and Senarmont compensators, often used by mineralogists, introduce a variable and measurable ‘compensating’ retardation which cancels the material retardation to give black.

At the turn of the 20th century polarised light was not widely used in the UK glass industry although it was more widespread in Germany and among the geological community for identifying

minerals. Early instruments were termed polariscopes although Americans used the expression strain viewer.

Historically polarised light was generated using strongly birefringent minerals such as calcite (Nicol prism).

Later the creation of polarising sheets based on oriented long chain polymeric molecules produced the same polarising effect. Large sheets are expensive but a similar effect could be produced using a glass sheet. If set at the ‘correct’ Brewster angle reflected light is weak in intensity but 100% polarised. Combining this with a concentrated light source and a smaller polarising sheet gave a strain viewer a wide field of view for examining a bottle not only through its base but also when held horizontally.

Early issues of the Journal of the Society of Glass Technology include detailed drawings of such equipment for measuring stresses and over time they became vital for controlling annealing.

Experiments on the relaxation of stressed glass at different temperatures were undertaken using long transparent rods where the increased path lengths gave measurable retardations even if stresses were low. The glassmaker could improve his productivity where previously poorly annealed articles broke during cutting.

It even became possible for workers to observe stress development during manufacturing by wearing glasses with polarising lenses. The science of glassto-metal seal manufacture developed by combining mathematical modelling with practical measurements using polarised light will be taken up later. �

Potential trainers and speakers are invited to submit an abstract of their proposed paper to Christine Brown, at the SGT, by the end of December. Christine’s email address is christine@sgt.org.

PSR appoints three staff

UK glass engineering group Parkinson-Spencer Refractories has appointed three members of staff in various roles.

Tom Foster has been appointed Project Sales Manager, Alex Packer has joined PSR as Sales Engineer while Lizzy Healey has joined as Sales Office Assistant.

Hotwork success

www.glass-international.com

Hotwork International has successfully completed a furnace project in Indonesia.

The Swiss group completed furnace glass draining, furnace heat up and a cullet fill with expansion control at both PT Muliaglass’ float and container furnaces.

A similar project with NSG Float Glass in Vietnam has also been completed.

A number of furnace heat-ups, furnace draining and other service projects in South East Asia were recently completed by the group.

Forglass moves offices

Polish furnace and batch house specialist, Forglass, has relocated to new premises.

The new office address and telephone number are: ul. Kosciuszki 32/1, 30-105 Kraków, Poland.

Tel. +4812352 4222.

Its NIP, REGON and KRS numbers and email addresses remain the same.

Community of Glass Associations launches website The community of Glass Associations has launched its website, www.communityofglassassociations.com.

The project grew out of ideas raised at the first International Convention of Glass Industry Associations, held in Murano, Venice, Italy, in June.

The two-day event was the first time internationally-based industry representatives had come together to openly and jointly tackle the most relevant topics of interest to the global glass industry.

During the sessions, it

seemed only natural to find a way to extend and unify the dialogue through the creation of this Community.

The Community’s mission is to provide the international associations representing the world of glass with a meeting place, and a functional means for continuing the dialogue that began in Murano.

The next meetings of associations is due to take place at the Vitrum event in Milan, Italy on October 4.

The idea is to meet annually, gathering each Spring to take

stock of and bring everyone up to speed on work in progress.

The Vitrum event, which organised the Community meeting, said: “We hope that the Convention of Associations will become a viable opportunity - a must for the industry - for constantly maintaining the dialogue around current industry affairs, its goals for the future and the challenges that will become increasingly feasible to tackle together, in a genuine atmosphere of partnership and cooperation.”

Vitrum offers matchmaking service The matchmaking system is back again this year at Vitrum 2017. Vitrum is a trade show specialised in machinery, equipment and special products for glass processing that

will take place October 3-6 at Fiera Milano Rho, Milan, Italy.

Visitors can use this service to plan their business appointments by finding the exhibitors they are interested

in, visiting and asking for an appointment at their stand.

The free service means industry professionals can maximise their time and efficiency at the show.

Delegates hail successful seminar

Delegates from all around the world attended the recent 14th International Seminar on Furnace Design – Operation and Process Simulation.

Organiser Glass Service (GS) said the June event, held in Velke Karlovice, Czech Republic, highlighted the latest developments in furnace optimisation.

The event was attended by about 150 glass experts from USA, Japan, China, India, Russia, New Zealand and several European nations.

In conjunction with the Seminar, on 20 June, the ICG Technical Committee 15 & 21 Meeting and the GS Glass Furnace Model (GFM) User Meeting were held in conjunction

with the seminar.

The event takes place every two years and brings together 150+ glass experts to discuss the use of simulation & control tools, with the goal of optimising the glass melting and forming process.

Russian market analysis Russian information and analysis VladVneshService (VVZ) presented a keynote report titled ‘Trends and Current State of the Russian Market of Raw Materials, Flat and Hollow Glass’. VVZ is one of the originators of the business connected with processing and analysis of market statistics that are used to make strategic management decisions.

Glass container production in Russia has grown continuously in contrast to flat glass production which has grown more slowly. According to VVS, in 2016 Russian container glass enterprises produced (Pic. 1) nearly 10.6 billion glass bottles (or 6% more than a year earlier).

They also produced (Pic. 2) about 2 billion of glass jars (5% more than a year earlier). According to Q1 2017 results, glass bottle production volume exceeded the previous year’s results by 4% and glass jar production grew by 5% compared to the previous year.

Russia’s Vladimir region is the largest producer of glass bottles, where a number of factories are located, the main of which is Rusjam and the Red Echo. The Volgograd region leads the way in the production of glass jars, in particular, the Kamensk glass container plant.

The structure of glass bottle consumption for packaging in Russia is beer 54.3%; vodka and cognac 24.7%; Non-alcoholic beverages 9.5%; wine

and champagne 6.5%; juices and other 5%. The import and export of glass containers here is presented without taking into account the trade within the Eurasian Economic Union (EAEU). Bottle imports in 2016 (Pic. 3) amounted to 55 million units - almost half as much as a year earlier. However, since the beginning of 2017 there has been a rise in imports.

Bottle exports continues to grow (Pic. 4).

In 2016 about 500 million bottles (+ 11%) were sent to foreign countries, while in 2017 growth continues by + 10%. Imports come from mainly Lithuania (30%), Ukraine (18%) and the Netherlands (14%). The export of glass bottles from Russia mainly goes to Azerbaijan (18%), France (15%) and Ukraine (13%).

Import of glass jars in 2016 amounted to 34.5 million units, lower than in 2015 by 22%. In Q1 2017, the amount of imports increased 68% compared to Q1 2016.

Exports of glass jars in 2016 amounted

to 86 million units, exceeding the result of the previous period by 22%. In 2017, exports fell 16% less than a year earlier.

The leader among the partner countries in the import of glass was Germany, which in Q1 2017 accounted for 75% of the total volume of imports. The most jars for export were sent to Azerbaijan (32%), Ukraine (18%) and Moldova (16%).

The production of glass bottles in Russia in 2016 slightly increased due to the stabilisation of the alcohol market. If the current trend persists, the output of glass bottles will grow approximately 1% in 2017 (Pic. 5). The production volume of glass jars will continue to grow under the influence of the growth in the production of canned vegetables and coffee.

World of Glass conference The two-day World of Glass 2017 international conference was organised by Expocentre.

Glass companies and associations reported on trends in the production, processing and consumption of glass products, mechanisms of implementation of new and efficient glass-based materials in mass construction and energy-efficient technology. 2017 is officially the Year of Continued>>

Ecology in Russia. Unfortunately before now in Russia d id not have separate municipal waste collection. on average each inhabitant in Russia produced about 450 kg of municipal waste per year, which included about 8% of glass. Practically all waste is sent to landfill and part-buried without recycling. It is key issue for Russia now.

Defects no longer know where to hide

Intelligent engraving inspection The Evolution 12 engraving identification and inspection module is a software innovation that allows the machine to identify engravings in a container’s body or base.

Because it is very difficult to predict how an engraving will look, this module dramatically improves inspection in these areas. By calculating the position of the engraving, the machine identifies the pixels related to the engraving, as well as those that relate to a defect.

This algorithm has been improved and tested over recent months on several production lines, including those devoted to beers, carbonated beverages, wine and high value spirits.
