....PROCESS....
This document explains the process I created and utilised to create innovative installation pieces out of Newspaper and White Paper. The process used to create these pieces encourages you, the user to interact with paper in a way that you will not have previously experienced. Through the hands on making and manipulation with the material you will begin to understand it possibilities and limitations as a material, which will hopefully inspire you to create wonderful things. This process of working and creating using paper can be and should be applied to other materials, so you begin to understand how they work also and encourages an alternative interpretation of the materials through critical reflection.

....MAKE NEWSPAPER PULP....
All of the following processes require the raw
ingredient of newspaper pulp. To create it follow these instructions:
1. Newspaper is ripped up into small pieces and layered into a bucket.
2. Two kettles of boiling hot water are poured over the paper until fully submerged and then
left for three days for the newspaper’s cellulose fibres to break down.

....MAKE PAPERCRETE USING A PROCESS SPECIFICATION....
A step by step construction guide on
everything you need to consider to make your own version of the papercrete stools on the opposite page. To work out how much it will cost you see page 37: EQUIPMENT NEEDED: 1 bucket
Stucco mixer attachment for screw driver 1 mould
MATERIALS NEEDED:
1 bucket filled with newspaper pulp 1 kettle of boiled water
1 margarine tub of sand
2 margarine tub of cement

1. Soaked newspaper put into a black bin and more water added to ensure the newspaper is covered.
2.Stucco mixer attachment used to mix soaked
newspaper for 10 minutes or till an oatmeal consistency is achieved.
10
11
3. Squeeze the excess water out of the
newspaper pulp using two sieves that fit inside each other.
4. Add two parts of Portland cement to one part of sharp sand and mix using a stucco mixer.
12
13
5. Add two parts of newspaper pulp to the cement and sand mixture and mix using a stucco mixer.
6. When mixed thoroughly add 1 part water and mix again using the stucco mixer.
7. Repeat steps 5 and 6 two more times so the finished mixture contains 6 parts newspaper pulp, 3 parts water, 2 parts Portland cement and 1 part sharp sand.
14
15
8. Once thoroughly mixed take mixture out
and start to layer it into the mould (for orthographic drawings on how to make them see page 22). It is important to do this in layers to
ensure that each layer is pressed down well to reduce the amount of air gaps.
9. Leave in a well ventilated area where there is a constant temperature for 2-3 weeks. After 2 weeks remove the mould to allow the
papercrete to be properly ventilated and to aid the drying out process. To be able to compare
your observations of the papercrete as it drys out with the observation of one of my samples as it dried see page 34.

....MAKE PAPERCRETE USING A PERFORMANCE SPECIFICATION.... This specification differs from the process
specification as it states a performance criteria that the papercrete sample must fulfil. The mix I used for the process specification does actually
fulfil these performance criteria, which should give you some idea about how the element’s quantity in the mix influences its performance. This is just another way of looking at how a material can be specified.

...MAKE PAPERCRETE MDF FORMER’s...
To make the papercrete stools you need to
create some MDF moulds to contain the material while it drys. The orthographic drawings and
cutting lists on the following pages will aid you with the former creation to replicate the stools that I created. The MDF moulds are constructed
using butt joints and lots of PVA glue so that they will be easily removed when needed.

...TO UNDERSTAND PAPERCRETE PROPERTIES...
The recipe shown in the guide is just one
option, with the properties that I found from my sample of the same mix recorded under
Mix 14 observation’s. This table has been used to record the possibilities and limitations that
I have experienced from making papercrete
samples over a period of nearly a year. This table will hopefully give you an idea about
what manipulations could be done with the papercrete mixes to get samples with different
properties. It also includes my critical reflections on each property discovered as it was through
these reflections that I was able to further the sample materials.

.MAKE PAPERCRETE STOOLS CHEAPLY.
One of papercrete’s most lucrative property is that is a cheap to make and quite
environmentally friendly, as it is made up of
70% recycled newspaper. Opposite is a copy of the cost analysis created to work out how much each stool cost to make. By doing it
individually I was able to ensure that I kept under my budget of £150. By working out how
much papercrete cost to make per 1m³ I was then able to compare it with other materials, which highlights its low economic cost.

.MAKE PAPER PULP LIGHT INSTALLATION USING A PROCESS SPECIFICATION. A step by step construction guide on everything you need to consider to make your own version
of the paper pulp light installation on the
opposite page. To work out how much it will cost you see page 53: EQUIPMENT NEEDED: Bucket Mould
Hand blender MATERIALS USED:
Pre pulped newspaper Polyurethane glue
40
41
1. The newspaper pulp has the excess water
squeezed out of it using the two sieves which fit inside each other. 2.
In
a
smaller
container
the
squeezed
newspaper pulp is blended for 10 minutes with
a hand blender with polyurethane glue added to the mix gradually until a sticky well blended consistency is created.
42
43
3. The material is then applied to the moulds in thin layers and left to dry.
4. Extra layers of the material can be then add-
ed to increase the strength of the final material in the desired form.
44
45
....UNDERSTAND THE PROPERTIES OF PAPER PULP...
When creating the paper pulp I have highlighted
the possibilities and limitations of the material
that I was able to understand as a result of making the material myself.
46
POSSIBILITIES Lightweight material Embedded strength from high percentage of polyurethane glue and epoxy resin glue as long as form is not broken
Majority of forms can be achieved if they are hollow Colour can be added to the mix if desired Blend of the material does not take long Easily cut and shaped Material has a high percentage of recycled newspaper content LIMITATIONS Process of layering to increase the strength of the material takes a long time as each layer needs about 2 days to dry
Material needs to applied to a hollow form - material wouldn’t dry if in a solid block Two types of glue used which are not that environmentally friendly
47
..MAKE ORIGAMI STYLE PAPER PULP FORMERS.. To make the paper pulp light installation you need to create gelflex moulds to form the paper
pulp on to. The gelflex shapes are made from MDF moulds whose orthographic drawings and
cutting list are on the opposite page, which will aid you with the former creation to replicate the shapes used in the light installation. The
triangle shapes need to be cut from 3 mm MDF and then stuck together into a 3D triangle shape using Gaffa tape along the length of the joints see page 51 for pictures.

1. Using the orthographic drawings create
the MDF origami inspired formers to pour the gelflex into. Line the formers with Gaffa tape to stop the gelflex from leaking out.
2. Melt the gelflex down in the moulten pot for about 2 hours stirring frequently
3. Using a ladle, spoon the gelflex into the MDF moulds and leave to set for an hour.
4. As the moulds are held together with Gaffa
tape they will be easily removed and can be used themselves to make paper pulp origami moulds.

One of paper pulp’s most lucrative property
is that is a cheap to make and quite

able to come in under my budget of £150 using this material. By working out how much paper pulp cost to make per 1m³ I was then
able to compare it with other materials, which highlights its low economic cost.

...MAKE SHEETS OF PAPER....
A step by step construction guide on everything you need to consider to make your own sheets of paper on the opposite page. EQUIPMENT NEEDED: Mixing container Hand blender
Screen printing frame Sponge Felt
MATERIALS USED:
Pre newspaper pulp Water
54
55
1. Add the pre pulped newspaper to a con-
tainer with extra water until it is quite water
logged. Using a blender pulp the mixture until the newspaper is finely blended.
2. Put the mixture onto to the mesh in the
frame over a sink and spread out evenly. To create a frame see page 58.
3. Place a piece of flexible acrylic plastic over the mixture and press down on it using a sponge to remove the excess water.
4. Once the excess water is removed take the
acrylic off carefully and leave to dry in a warm place until hard, usually about 3 days.

..MAKE PAPER MAKING FRAMES..
To make the frames use the orthographic
drawings on the opposite page. The frame
needs to be slightly bigger than the paper size you want it to be to allow for shrinkage and
to cut down rough edges. The mesh can be anything from lace or fabric with a larger weave to allow the water to seep through.
58
59
1. Using the orthographic drawings cut the pieces of MDF to size with a mitre joints.
2. Join the mitre joints together using the corner formers with plenty of glue for each joint.
3. Put two screws into each corner to ensure the joint is secure.
4. When dry stretch the lace or netting taught
over the frame and using a staple gun fix it to the inside of the frame.

..MAKE SHREDDED NEWSPAPER RESIN..
A step by step construction guide on everything
you need to consider to make your own version of the newspaper resin on the opposite page. EQUIPMENT NEEDED: Syringe
Volume measurer Mould
MATERIALS USED:
Pre shredded newspaper 4Ml mekp catalyst
250g water clear casting resin
62
63
1. 4ml of mekp catalyst measured out using the syringe
2. 125g of water clear casting resin spread around bottom of the mould creating a base layer
3. 2ml of mekp catalyst added into the mould with the clear casting resin and mixed together
64
65
4. Shredded paper is added into the mould onto the base layer of water clear casting resin and catalyst with the other half of the mixture added onto the top of the shredded paper
5. The material is left to dry for half an hour

....UNDERSTAND THE PROPERTIES OF NEWSPAPER RESIN...
When creating the newspaper resin I have
highlighted the possibilities and limitations of
the material that I was able to understand as a result of making the material myself.
68
POSSIBILITIES Waterproof and solid material Interesting colours can be seen through the resin Will take shape of any mould that it is poured into Takes 1/2 hour to set completely Any material could be used to be suspended in the resin LIMITATIONS Cutting and shaping the material once set will be hard Resin is toxic and needs to be used quickly as it will set once the catalyst is added Takes the exact mould’s shape Not a lot of newspaper is used in its creation and it isn’t an essential part of the material

...NOT MAKE NEWSPAPER WOOD...
A step by step construction guide on everything
you need to consider to make your own version of the newspaper wood on the opposite page. EQUIPMENT NEEDED: Bucket
Paintbrush
Old tray/paint tray MATERIALS NEEDED:
Stacks of old newspapers Polyurethane glue
70
71
1. Polyurethane glue poured into bucket and then applied to each page of 4 - 5 newspapers. 2. Newspapers stacked on top of each other in a bag with more
glue poured into bag
3. Weights applied to compress pages and left to dry for 2 weeks.

....UNDERSTAND THE PROPERTIES OF NEWSPAPER WOOD...
When creating the newspaper wood I have
highlighted the possibilities and limitations of
the material that I was able to understand as a result of making the material myself.
74
POSSIBILITIES Not as light as wood Able to be cut easily without blunting tools Interesting grains appear from the layering of the newspapers A lot of newspaper material is used in the production of the material LIMITATIONS Is hard to mould into a certain shape Takes 2 - 3 weeks to dry out A lot of polyurethane glue needed to get the needed adhesive strength - a second application of polyurethane was needed to allow correct adhesion
