Could have just bought replacement sliders, as I’ve never had any trouble with my old unitbeyond replacing the pads a couple of times. I decided to help the economy and buy the whole new shiny unit.

I like the new sliders. I got 26 years out of my first GG, and 26 years from now I’ll be 102 years old.

You may not have a chance to sell me another.”

T

his year marks Clay Times’ 15th anniversary in print. It still amazes me that our original local newsletter has evolved into such a widely embraced, worldrenowned magazine. Back in 1995, pottery making was a relatively obscure subject—even difficult to research at public libraries due to a widespread lack of available ceramics books and periodicals. But 15 years later, ceramic arts publishing has exploded into a vast ocean of information. And considering the downward spiral of printed periodicals during recent years, I’m especially pleased to report that thanks to all of you—our loyal supporters—we’ve weathered the storm and are firmly committed to making our next 15 years even stronger than ever!

roots Clay Times has established throughout the world ceramic community, we’ve grown a global communications network with a foundation strong enough to monitor the latest and greatest developments of the clay arts field on a daily basis. As a result, an expanded version of the magazine itself and our original Website at www.claytimes.com, “Clay Times Online ,” will debut in mid-April. It will serve as an unprecedented communications network and resource for ceramic educators and students, professionals and hobbyists, collectors, and clay enthusiasts worldwide, offering daily newsfeed and a single all-encompassing resource and forum where you may access and share anything and everything having to do with ceramics.

To achieve this goal, we realize that flexibility is key. We need to listen to the voices of our readers and advertisers, and do whatever possible to continue providing you with the very best of the services you desire. One very clear, overwhelming concern of late is the need for us all to operate on a ‘greener,’ more ecologically-aware basis.

Clay Times is answering that call in several ways:

• Several subscriber-only supplements to the print publication will now be available online throughout the year. As such, we are combining our previous 6 bimonthly print issues into 4 quarterly issues to be published in spring, summer, fall, and winter—PLUS we’ll be adding a colorful studio poster insert in each seasonal issue.

This will allow “fresh” clay news to be accessed online daily, and will greatly reduce the overall annual waste generated by paper used for printing.

• We’re now printing the magazine on 100% FSCcertified, 75% post-consumer recycled paper.

(The very green, new Vermont-based company that prints CT even generates 100% of the heat for their printing plant from waste captured from the printing process itself.)

• We are expanding our online, “paperless” presence dramatically. Thanks to the very strong

THE HERMAPHRODITES:

Living In Two Worlds term as it applies to sculpture that can be categorized equally as contemporary fine art sculpture or decorative art.

The exhibition concentrates on works by contemporary ceramic artists who also adopt other processes, materials, and techniques commonly found outside of their discipline. Featured artists include Chris Antemann, Beth Cavener Stichter, Cynthia Consentino, Anne Drew Potter, Judy Fox, Gerit Grimm, Bridget Harper, Sergei Isupov, Myungjin Kim, Dana Major Kanovitz, Kelly Rathbone Garrett, Dirk Staschke, Mara Superior, Tip Toland, Jason Walker, Kurt Weiser, Red Weldon Sandlin, Irina Zaytceva, and several others.

“The artists in this exhibition produce sculpture that is categorically often confusing when placed in private or public collections,” remarked show curator, Leslie Ferrin. “Depending on the curatorial mission of the institution or vision of the collector, works by these artists can be found in contemporary collections of fine art, decorative arts, and even, at times, design. The title of the show was chosen to first draw attention from its social meaning, and then challenge its interpretation from various metaphorical perspectives.”

Perspectives I As Far As I Know

‘Water Blue’ Glaze Revisited

Josh’s Water Blue Variation

Fig. 1: In the original article, this was color variation “O”, containing 8% red iron oxide and 6% copper carbonate (I’ve started calling it “Grass Green”). This cup experienced a very slow cooling cycle (the one detailed in the first article), developing a mirror-like iridescence. You can see examples of popped bubbles at the intersection of the bottom of the handle and the body, and also under the end of the thumb rest. The cross-hatch texture you see is scratched into the surface of the damp clay.

I

or the outsides of utilitarian pots (I wrote more about this in the first column). In fact, this glaze crazes so much, and the crazing is so close together, that it’s not terribly noticeable unless you’re looking for it. Instead, what tends to stand out with this glaze (besides the bright color and glassy surface) is the way it pools, revealing and emphasizing even the slightest textures in the surface of the clay.

As I mentioned in my previous article on this subject, Ferro Frit 3110 is a very alkaline frit, meaning that it will tend to have particular characteristics.

For one, alkaline frits (and, by extension, alkaline glazes) tend to have a clear, bright, relatively intense color response. Another characteristic of alkaline glazes is they have a higher than normal rate of thermal expansion, which means that they craze on almost any kind of clay body. Third, these glazes tend to be more fragile than usual; that is, they don’t stand up well to exposure to the acids or bases found in foods.

This crazing and fragility tends to limit their use to sculptural forms

Because of its alkaline nature, this glaze also has a tendency to settle. That’s because small amounts of alkali (sodium ions in particular) can leach out of alkaline materials, like this frit.

This soluble alkali will cause the clay portion of the glaze to deflocculate, meaning that the clay particles repel each other, rather than being attracted together, which allows the other, heavier particles in the wet glaze to settle to the bottom of the bucket. Someone added 3% bentonite to this recipe, obviously in an attempt to fix this problem.

Bentonite, by the way, is a very fine-grained volcanic clay that potters add to a glaze when there

Fig. 2: This color was variation “G” in the original article, containing 6% copper carbonate and 1% cobalt carbonate (I’ve started calling it “Blue-Green”). This cup had a scattering of popped bubbles throughout the surface after the first glaze firing. I painted a little dot of glaze over each of the bubbles, refired the cup, and the bubbles disappeared, leaving no residual mark. Note the slight roll of glaze at the bottom of the cup: the glaze became thicker at the bottom (over the course of two firings), but didn’t run off the cup. isn’t enough clay in the recipe to keep the other materials in suspension (note that this recipe contains only 7% EPK, which is a bit on the low side). However, if there is enough alkali, it can deflocculate the bentonite as well, so the glaze will continue to settle excessively (which is what this glaze did for me).

The remedy for this problem is addition of a solution of Epsom salts and water (yup, the same

Epsom salts that are sold in drug stores). Epsom salts act as a flocculant, counteracting the tendency of soluble alkalis to act as deflocculants. If you haven’t flocculated a glaze before, don’t worry—it’s quite easy. Dissolve a cup of dry Epsom salts in a pint of hot water (I do this in a glass quart jar). You can keep this solution in your studio and it will stay good just about forever. A small amount of it can be added to a liquid glaze to thicken it and prevent it from

n the November/December 2009 issue of Clay Times, I introduced some new color variations on the classic Water Blue glaze. I was intrigued enough with the glaze that I decided to use it myself. This experience has resulted in my learning more about the glaze, which I’ll share with you in this column. (Just to refresh your memory, the base glaze recipe appears in the box above.)

Water Blue Glaze (from p. 17) settling. For a 10,000-gram batch (that’s about 5 gallons of liquid glaze) you might add a few tablespoons. It’s not rocket science—just add a bit and stir the glaze, continuing to add until the glaze thickens and the settling stops. You may need to add some water after flocculating, but if the particles are flocculated, then the glaze won’t hardpan when it settles.

It will, instead, form a thick, soft layer on the bottom of the bucket.1

David Snyder of All Fired Up said, “Everything Paragon does is normally a grade above what is the standard for the industry.”

“Paragon is by far the most solid-built kiln made” —David Snyder David Snyder began repairing kilns at age 15 in his parents’ ceramic shop. He lives in Charlotte, North Carolina and services kilns in an eight-state area.

“Paragon is by far the most solid-built, virtually repair-free kiln made,” said David.

“I can honestly say it’s the best kiln made in North America.

“Over the years Paragon has led the industry in innovation,” David said. “I’ve always found that everything Paragon did was followed by other kiln companies two or three years later.

“As a professional repair person, I prefer selling a top quality kiln and then never having to worry about a warranty issue rather than selling a kiln of lesser quality and having to worry that I will have to make a trip for warranty service repair.

“I like the balance of firing in a Paragon kiln, and quality of construction,” he said.

“Their control boxes are heavy duty. The fall away easy access switch box is really nice. One thing I love about Paragon is the clear wiring diagrams for every kiln they make. Elements are pre-stretched with pre-bent corners, so there’s no worry about the element fitting or not. New element connectors come with every element.

“The switch boxes are made of thick steel. They don't use cheap wire mesh on their switch boxes. The wire mesh is spot-welded and fails after a few years.

Stands are heavy duty. The galvanized steel base plate is a great feature especially for setting up a new kiln when you have to shift the kiln on the stand. For kilns without a steel base plate, you have to lift the kiln completely off the stand to adjust the kiln even a quarter of an inch. Otherwise the stand will dig into the bare brick bottom.

“Another factor is element design. One production potter I know does literally day in, day out cone 6 firings in his Paragon Viking-28. He had his kiln for right at three years before needing new elements. The element replacement in that kiln could not have been simpler.”

I’ve had a number of people request that I publish a recommended specific gravity for new glazes. Specific gravity is a measure of the relative density of a substance compared with a reference material, like water (for liquids) or air (for gasses). For glazes, we compare the weight of the glaze with an equal volume of water. Glazes always weigh more than water, because glazes are made from rocks, and rocks are almost always heavier than water (even when finely ground). This is why all those rocks we tried to skip across lakes when we were kids tended to sink—the rocks had a higher specific gravity than the lake. For purposes of comparison, we assign water a density of one (1.0), so things that have a lower density than water have a specific gravity of less than one, while those with a density higher than water will be more than one. For instance, the oil that you put in your car has a specific gravity of about 0.9, which is why leaked oil in a parking lot will float on the water in the pot holes.

Glazes are heavier than water, so their specific gravities will always be higher than 1.

The best way to measure the specific gravity of a glaze is by weighing it. I use an electronic digital scale and a large plastic cup (it came with an immersion blender) that has milliliter gradations on its side. Place the empty cup on the scale and press the tare button so the scale removes the weight of the cup. Then pour the glaze into the cup until it reaches the 500 ml line (and do so as accurately as you can). Divide the total weight of the glaze by 500, and you’ll have the specific gravity. If your scale won’t handle that much weight (over 600 grams) or you don’t have that large a graduated cup or cylinder, then you can use a smaller cup. Just remember that you divide the weight of the glaze (in grams) by the volume of the glaze in milliliters. I don’t measure the specific gravity of glazes very often, but it is an excellent way to make sure that your glazes are the same density every time, which can prevent the loss of work from applying the glaze too thinly or too thickly.

I mixed several batches of these glazes (in different colors), adjusting each of them by feel. When I weighed them for this column, I was a bit surprised that the specific gravities of all were almost identical: about 1.4 (each 500-ml cup weighed about 600 grams).

Bernadette Curran (continued from previous page) I think they don’t believe what I do until they hear it from someone else. My sister in North Carolina called me one day, flabbergasted because my niece’s art teacher had one of my postcards hanging in her office. My brother in Arizona e-mailed me in awe of how many hits my name had on the Web. Then he proceeded to ask me to make him a dinner plate with an image of his cat on it, and he attached a photo of his cat.

In my first year of graduate school when I was floundering about, Rebecca asked me a very helpful and yet obvious question: “What don’t you like historically in ceramics.” I found that much easier to answer than “What do you like?”

Wilson: How did you find out about the soda ash in a glaze creating that orange fuming effect?

Curran: Oh yes, the orange fuming—a very happy accident/discovery.

In anticipation of my thesis show, I had been firing all of my pots in the soda kiln, until one frightening day when the tech revealed that the soda kiln would be shut down for repairs. Why now? Why me? My pots were relegated to either the electric kilns or the downdraft kiln. In those sleepless days before the show, I chose electric.

To my surprise, I found that certain glazes continued to fume as if they had been in an atmospheric firing—perhaps not as intense or concentrated, but there was some action. At the time I was disappointed, but then I realized I wasn’t going to have access to a soda kiln after graduation. I started to pay closer attention to which surface combinations and juxtapositions would instigate this faux soda. The drawn images actually became easier to read without the heavy, unpredictable deposit of ash on the surface. It definitely took some time to warm up to the idea of oxidation firing.

several reasons. Because Peter focused on the ‘positive’ in my work, it took away my fear of making something wrong. So I wasn’t afraid of making anything—and there were a lot of bad ‘anythings,’ but among them were some interesting beginnings. I recall one wild thing I made early on that was ghastly, but humorous and intriguing to Peter during our first critique.

It was an oversized majolica frog sitting in an earthenware basket. Indeed this was a catalyst for my love of drawing animals and playing with narrative on a threedimensional form. Peter was also responsible for encouraging me to put my pots out in the world for sale, which at the time seemed foreign. What? Sell things I make?

It was wonderful. I will always remember the first $15 I made. Having an audience with feedback made it very real.

Wilson: Tell us about your undergraduate work and MFA experience.

Wilson: What was the early style of your work?

Curran: I have a BFA from Pennsylvania State University where I studied with Chuck Aydlett, Chris Staley, and Liz Quackenbush. I spent equal time with all of them. I also apprenticed with Liz for two summers, so we became very close and continue our friendship to this day. I went to Ohio State University in Columbus, where Mary Jo Bole and Rebecca Harvey teach. Most all of my interaction there was with Rebecca Harvey and faculty from other disciplines, in particular the bookmaking and print-making teacher. I also studied with Peter Beasecker as a Special Student for one year. Studying with Peter was pivotal in my development for

Curran: The theme of animals as a catalyst for making pots came about early on after having taken a workshop with Ron Meyers, but it was the execution of the animal as both a form and surface that went through transitions to come to my current work. Early on, I experimented with the human figure as subject matter, but at some point it became too serious, too close to me. Animals not only allowed for personification, but they had these wonderful gestures, skins, and bloated body parts that intrigued me.

Wilson: What provocative or helpful questions were you asked by your professors?

Upon reflection, it may have behooved me to delay graduate school for a year or two more than I did. I think some maturity and maybe another residency could have given me a little bit more focused direction.

Wilson: How many years did you support yourself with your work? What were the best and worst of those years?

Curran: I supported myself through my work and teaching gigs at community art centers for five years. The best part was that I was actually able to do it and come out ahead, even after all my expenses. The worst was making novice wholesale decisions that stifled my creativity and selling pots too cheaply. It was also difficult being the newest faculty at the local art centers; I got the leftover classes that no one else was willing to teach. But that pre-teen wheel class helped pay my studio rent.

Wilson: Do you think you are more interested in form or surface, or equally interested in both?

Curran: I am equally interested in both form and surface. Depending on the pot’s use, it will lend itself to one or the other.

For example, a plate is a blank canvas for surface, while a butter dish calls for form.

The challenge and intrigue is bringing those two worlds together on one pot. I would describe my body of work as falling into three categories: animals drawn on the surface of a simple pot (surface), animal or abode as pot (form), and third, the serendipitous pot that is one and the same, both drawn and moving in space as an enlivened volume.

The Project A chip ‘n’ dip server is one of the most useful pieces of pottery we can make. Every household I’ve ever been in has at least one of them: big bowls and little bowls. How we put the two together can make the finished piece interesting and salable, or boring and

So, to get them moving in a creative direction, talk about, draw, and show them this bit of magic: how to make three bowls from two bowls, and then combine them to end up with one finished piece—a threebowl chip ‘n’ dip server (Fig. 1).

Diagramming projects like this one can often be a real help. Some students can easily relate to the making steps if they see them drawn first, through drawings made without too much detail, yet enough to get the idea across (Fig. 2, next page).

Then, as you attach your first ball of clay to the bat, describe again the magic trick you’re about to perform: “I’m going throw two bowls now, and let them dry a bit. Then, I’m going to turn my two bowls into three bowls and combine all three to make one finished piece. It may seem complicated, but it’s really not as difficult as it sounds.

Hang in there and watch. And it starts by throwing, or handbuilding, two identical 3-lb. bowls.”

You can push, or pull, the wire underneath the pot from front to back or back to front. The direction doesn’t make much difference one way or the other; just have confidence and be comfortable doing it.

Now make a second bowl the same size and shape as the first. Before you remove your first bowl from the wheel, however, record the height and width, then use those measurements to make bowl #2. You can use a ruler or try this simple measuring method: push a chopstick into a small ball of clay, and secure the clay to the edge of your splash pan or water bucket. Position

EUCLID KILNS

Electric Kilns: Maintenance & Firing

BY JOANIE TURBEK

A

s every artist knows, it takes a wide variety of skills to successfully create fine art. Ceramists are no exception; the most successful of us can wear the hat of chemist or contractor as easily as that of a kiln technician, photographer, or graphic designer. These hats represent the tools we need to enable the most control over our final product and how it is perceived in the marketplace. With ceramics itself, there is always something new to learn, and while this is an invigorating aspect of our material, it is often intimidating to learn a whole new set of skills. With this in mind, The Clay Studio in Philadelphia has rolled out a line of workshops called “Get smARTs”™ that focuses not only on new ceramic techniques, but also on the supplementary skills that emerging artists need to effectively represent themselves.

Jennifer, The Clay Studio’s General Manager, guides participants through the best ways of firing and programming schedules for electric kilns. She leads discussions about strategies for getting the most out of kiln sitters, cones, holds, and firing down to get the results you want. The workshop also offers insight on money-saving techniques for ceramics studios, like how to replace elements, soft brick, thermocouples, relays, connector wires, and other basic equipment in your kiln that you can maintain yourself. That being said, Jennifer offers Clay Times readers these ten indispensable tips to help keep your electric kiln cookin’!

10 Tips Every Electric Kiln Owner Should Know

Since The Clay Studio’s mission is intimately tied to the education and promotion of ceramic artists at all levels, the new Get smARTs workshop series is a perfect fit for the education program. We recognized early on that even when individuals have progressed beyond the point of taking classes, there is still a distinct need for support on topics ranging from equipment maintenance to marketing art in a smart and effective way. Get smARTs offer an opportunity for local artists to learn from their peers in the community. In a low- cost, high-impact format, we offer these short, three-hour workshops at affordable prices while retaining the flexibility to schedule timely workshops that are most pertinent to our community.

Before starting any maintenance on your equipment, remember (especially if you are having a problem) … Unplug your kiln! Make sure that your kiln is unplugged or turned off at the power source.

Protect your shelves by covering them with a light coat of kiln wash. Kiln wash will provide a barrier to prevent the glaze from sticking to your kiln shelves. Kiln wash generally is made from a combination of kaolin and aluminum hydroxide, and can be purchased pre-mixed from most major ceramic suppliers.

Make sure your kiln is an appropriate distance away from walls and furniture.

As a general rule, kilns should be 18' away from walls, shelves and furniture. However, notwithstanding this rule of thumb, always read the manufacturer’s recommendation before installing a kiln.

[2] Let it Breathe Proper venting is crucial to maintaining safe equipment. As your kiln is fired, it may

It’s not just for rugs anymore! Be sure to vacuum out the bottom of your kiln, as well as the grooves that hold the elements.

This will extend the life of your elements and keep the brick walls of your kiln in good shape.

[5] Handle with Care Treat the top of your kiln with special attention. Although it may be tempting, avoid stacking anything on top of your kiln.

The top of your kiln is made of fragile soft bricks that will eventually crack and cave in if weight is placed on them, or from the impact of the lid being closed forcefully.

If you suspect that one of your elements is not working, take a standard wooden pencil and place the lead on the element when it is cycling on.

Opening the kiln when it is hot can damage your work and cause wear on the elements.

Do not open the kiln when it is hotter than 450° Fahrenheit (F). If you do not have a pyrometer gauge on your kiln, you can stick a strip of paper into the spy hole of your kiln.

If the paper starts to smoke, the kiln is hotter than 450° F. If the paper does not burn, crack the door approximately 2" until the air inside the kiln feels warm but not hot, approximately 200° F.

[10] Elements are Elementary If you do need to replace your elements, The Clay Studio does not recommend changing kiln elements without prior experience and cannot be held responsible for errors made in installation. This being said, for those with prior experience or instruction, elements can be replaced with just a few basic tools, patience, and some time. (I know we said it before, but always start by unplugging the kiln! It should have no connection to an electrical source while you work with the elements.)

New elements will go in the same way the old ones came out (some kilns require the elements to be pinned in place with hightemperature wire). It is also important to label and diagram where all of the elements and wires are attached. Always consult your kiln manufacturer or local supplier to make sure you have the correct elements, as elements are often specific to a particular model. Also, sometimes the new elements may be slightly short or long, but don’t worry—a little crimping or stretching will take care of that. Once you are done, make sure you test-fire the kiln to ensure that any residue on the elements is burned off. And remember: don’t forget your cone packs! [

New Kilns & New Valves BY marc ward

I

t’s the spring issue and I’m going where I usually go. This article is about new kilns and kiln building; specifically, about the new valves you’re going to be using on old or new burners. To begin with, let’s talk about the little codes, letters, and chicken scratch that appears on the body of shut-off valves:

Since 9/11, folks in North America have seen governments and authorities doing their best to protect us more (even if we don’t want protecting). This is not a political rant, just an observation of what has been going on in the gas world regarding issuance of permits, and compliance. More and more inspectors and installation folks have been looking for specific symbols on gas equipment. Here’s a brief rundown on what they stand for, and what they mean: UL — Underwriters Laboratory. This is a private organization that tests all sorts of things. A manufacturer has to pay big for a listing with them! There are things that are not UL-listed that are perfectly safe, but not things that are UL-listed that are dangerous. If you pay for the service and UL lists your product, it is accepted as safe and insurable.

Many valves have this listing, but many do not—which most often means the manufacturer didn’t want to spend the money for listing, not that the product was basically unsafe.

CSA — The Canadian Standards Agency was similar to UL. It is now known as CSA International. It has three approvals: the CSA for Canada, CSAus for the U.S., and

WOG — This is usually followed by a number like 250, 400, or 600. It means Water, Oil, or Gas at 250 psi, etc. If this is the only marking, these valves have not been sent off for listing. It doesn’t mean they don’t work, but you’ll have a harder time getting them past the inspectors. Remember, inspectors generally don’t make independent decisions; they enforce rules, and many rules state you’ve got to have a “listed” valve.

WSP — Preceded or followed by numbers (psi): It means Wet Steam Pressure.

CWP — Cold Working Pressure. This and WSP don’t have much application for gas or burners as far as inspectors are concerned.

FM — FMGlobal is an approval agency similar to UL, but more directed at commercial products than consumer products.

Many times, an FM approval is harder to come by than a UL approval, but since it is more industrial-based, it is not as recognizable as UL. CGA — This is a tricky one. There is a Compressed Gas Association that deals with medical gases and industrial gases, but when you see this on a valve it means the Canadian Gas Association has approved it. There are subsets under the CGA that conform to CSA standards.

ANSI — American National Standards Institute. These guys set standards, then

folks like UL put approvals on things that have lived up to the standards. ANSI codes (usually followed by numbers) are usually only seen on industrial products. You generally won’t see ANSI without association with an approval such as CGA: • CGA 3.16 — Approved to ½ psi • 5g — Approved by CSA to use for 5 psi • 125g — Approved by CSA for use to 125 psi.

Just be aware that one valve might have all three of the above stamps relating to pressure. If you see the CGA 3.16 stamp, it probably doesn’t mean it is only good to ½ psi. There may be other pressure stamps (and there may be other stamps I haven’t covered) scrawled all over your valve like strange markings from the Roswell crash site. Many of them pertain to valve body materials, model numbers, and such.

So, that was fascinating reading, right?

After pondering all this, you may not necessarily be inspired to do much of anything with it, but you should save this information in a spot where you can find it later. When the gas inspector, fire marshal, or neighborhood busybody makes a fuss, this may be some ammunition you will find useful.

Next issue, I’ll tell you about some of the kinds of valves these markings can be found on, and whether or not they’re appropriate for gas-fired kilns. [

AGA — American Gas Association. No longer a functioning entity, but you will still see their logo. They were bought by CSA in 2007.

CSA International. These guys are now pretty specific to gas equipment and testing, so if your gas guy starts talking AGA, you can pull out your trump card and say, “I guess you’re unaware that AGA was bought by and became part of CSA International and CSAus in 2007.”

SHINO REDUX 2010 a national invitational exhibition curated by Malcolm Davis

S

HINO REDUX 2010, a national invitational exhibition featuring a wide variety of works glazed with shino and carbon-traps by 74 clay artists, recently took place at the Clay Art Center in Port Chester, New York. Shino, a generic term for a family of pottery glazes that originated in Japan in the 16th century, is a glaze that has captivated the imaginations of hundreds of potters for hundreds of years. This particular exhibition sequels a similar Baltimore, 2005 show curated by Malcolm Davis. Shino Redux 2010 is an updated version of that exhibition, featuring new artists on the shino scene as well as many who are recognized for their superior accomplishments with this challenging glaze medium.

In the words of curator Davis, the exhibition featured “all manner of pots and nonpots, white and gray, peach and salmon, fat and thick, quiet and dramatic, big and small, crazed and crackled, crawled and pitted ... even some yellows and some blues, and some work that challenges the meaning of what makes shino shino. He concluded that the final exhibition featured “a magnificent spread” of works.

Clay Art Center is a not-for-profit ceramic art organization offering exhibitions, clay classes for adults and children, studio spaces for clay artists, and outreach programs in the community. For further details, e-mail leigh@clayartcenter.org or call 914.937.2047. [

The Basics of Throwing: A Practical Approach to Form and Design by David Cohen A&C Black • University of Pennsylvania Press • Paperback • $24.95 Is there a subject more written about in the potter’s archives than throwing? I don’t think so!

So what is it about this one that has my attention? Let’s start with the subtitle: A Practical Approach to Form and Design. There is a sophistication and recognition of the fundamental, and arguably the most important, basis of creating objects: form and design. I’m thinking that if Cohen can teach throwing and deal with these issues, we’ve got a winning combination.

The Basics of Throwing is divided into nine chapters, and in 144 pages the reader is taken from the properties

The final chapter introduces us to five potters whose work the author hopes will encourage, inspire, and excite the reader. Trust me, they will. Cohen’s throwing methods are personal, as are all potters’ approaches. You will see him center, pull cylinders, and form shapes in his own way that may fly in the face of the way you have already been taught. This is to be not only expected, but embraced, because throwing is very personal. We take elements of technique from different sources and teachers, then meld, combine, and personalize them until they work for us.

Although the instructional text is clear, detailed, complete, and comfortable to read and follow, the strength of Cohen’s teaching lies in his consistent focus on form, design, craftsmanship, and creativity. He talks about throwing in series, analyzing and criticizing your work, and the technical and visual vocabulary of design. These are the elements that distinguish The Basics of Throwing from other books on the subject. There are many excellent books on throwing.

Is this the best one? Only the reader can decide that, but from where I sit, it is at least near the top of the list.

Ceramics for Beginners: Hand Building

by Shay Amber • Lark Books • Hardcover • $24.95.

Lark Books knows how to produce craft books, and this series is no exception. Bright, colorful, and imagedriven, Ceramics for Beginners: Hand Building takes the individual new to clay through all of the basic steps of handbuilding. The first part of the book introduces the reader to materials, tools, equipment, process, and the workings of the studio. Amber presents the essentials without burdening the reader with unnecessary technical details that would only confuse and be of no practical use. Clay composition, clay bodies, color, texture, plasticity, stages of dryness, and reclaiming clay are some of the issues discussed. In the section on getting to know the studio, she introduces the reader to the workspace, discussing safety, tools, equipment, furnishings, kilns, and more—again, with just enough detail to make the information understandable and useful.

The instruction is project-based, going from elementary to complex and presented within the categories of pinching, coiling, slabs, and making and using stamps. All of the 12 projects are simple in concept, yet sophisticated in design and aesthetics, covering both vessel forms and sculptural objects, functional and non-functional work, simple forming, and more complicated construction. There is a relaxed, comfortable approach taken by the author that the reader will enjoy.

Each chapter ends with a selection of work by established clay artists that is stimulating and exciting, but not intimidating. The work is clearly chosen to inspire readers and push them to new heights. Shay’s instructional text is clear and easy to follow, but not at all juvenile, and flows in and out of the full-color

photographs on every page. She is an accomplished and passionate teacher, and this is evident in the careful details and encouraging style of her instruction. Glazing and firing are introduced in the final two chapters, where she gives the reader the basics: just enough to understand, proceed, and instill confidence, but not so much information that it becomes frightening or overwhelming. A basic understanding of glazes including materials, different appearances, and preparation of ware and glaze, is followed by simple application methods and troubleshooting. A short section on firing gives the reader a familiarity with kilns, loading, and firing. Finally, there is a small selection of slips and glazes simple enough for the beginner to start experimenting with.

Ceramics for Beginners: Hand Building is for pottery students of all ages and will be equally useful in the hands of a middle school art teacher, high school pottery teacher and her students, or the adult working at home, or as an adult-education class text. It’s now in my school studio library. Good job, Shay! [

If you are a regular reader of this column, you probably know that I always start a book by reading the author’s introduction (and you should, too). Cohen’s intro was the hook. His sensibilities and the issues that he finds most important are those with which I identify and focus on in my own teaching: mechanics, ergonomics, mental attitude, sense of rhythm, posture, critical thought, and emotional and physical response. Relate to these elements, and you are well on your way to understanding clay and what you can do with it.

of clay to teapots, advanced forms, and complicated expressive approaches. The style of the book is image-driven. The 475 well-done, carefully chosen photographs with extensive instructional captions and overlay details are easy to understand and utilize. Especially helpful are the cutaway photos showing hand and finger position, wall thickness, and other nuances of the potter’s craft. Interspersed are helpful technical details that many books overlook: attaching a wooden bat to the wheel, the mechanics of the potter’s wheel, and making a cut-off wire, to name a few. Cohen covers a variety of forms, handles, lids, spouts, trimming, and more.

Scales are essential pieces of equipment for the pottery studio—but which ones do you need, and for what?

Read on to discover the latest, greatest models Vince has come to prefer for clay and glaze materials ...

W

hen I first learned ceramics, the only scales we used were triple-beam balances for glaze materials and industrial platform scales on wheels for mixing clay. The range of equipment available today is a bit mind-boggling. I will discuss a number of electronic balances available, but some of the old-fashioned mechanical scales are still going strong, and are often the best choice for the clay studio. If you can’t find the following scales at your favorite ceramic supplier, try: www.affordablescales.com.

The Triple-Beam Balance

I should mention that the Adams Equipment® TBB-2610T triple-beam balance costs less than $100 including tare beam and accessory weight set. I have not used this scale, but it looks good.

There is one primary advantage to the classic triple-beam balance that is missing from the less-expensive electronic digital scales that are becoming increasingly popular in ceramics studios. With the triple-beam, you can set the desired weight and add to the weighing container until the balance beam moves. Once you get used to this, it goes very quickly, and you can weigh out exact amounts rapidly. The bargain electronic balances only tell you the amount of weight on the weighing platform, and thus you must watch the digital readout very carefully in order to stop when you reach the desired weight.

There is something reassuring about the certainty of a mechanical-beam balance where all the parts are visible. If you learn to use the Ohaus triple-beam balance properly, zero the weighing container, and avoid physically damaging the unit, it is foolproof.

Countertop Dial Scales When weighing out lumps of clay for throwing, the traditional countertop springbalance dial scale is still my first choice. Bailey.com has the Pelouze® YG-80 for around $70. It weighs up to 50 lbs. and is ideal for general studio weighing tasks where high precision is not needed. Personally, I prefer the more industrial look of the Detecto® T2-5KP for around $95, with a maximum capacity of 55 lbs. The Detecto scales also have dual concentric readouts showing both pounds and kilograms.

Electronic Digital Scales An ever-increasing variety of electronic digital scales is available, ranging from reasonably priced to very expensive.

There is no reason to get an expensive one, because they are generally intended for specialized applications beyond what we need in the glaze lab. As long as you stick with those designed for general weighing purposes, an electronic scale will often be far less expensive than a precision mechanical scale.

The “old reliable” Ohaus® triple-beam balance is still the standard in most studio and university glaze labs throughout North America. The most popular unit is the Ohaus model 760 with tare beam for around $180. The tare beam allows you to zero the weight of the empty container, which is a great advantage. Without the tare beam, you have to weigh the container separately, and then take that into consideration when weighing your material. The capacity of the model 760 is only 610 grams, and thus the accessory metric weight set for around $35 is mandatory.

The weight set includes two 1000-gram weights and one 500-gram weight that hang on the end of the balance beam in different combinations, allowing precision weighing up to 2610 grams.

If you get the Ohaus 760 balance with tare beam, I recommend the Ohaus “Maxi-Scoop” for around $23, a sturdy, all-purpose weighing scoop that fits the scale platform. You do not need the one with the tare weight, because the tare beam on the scale will accommodate that. Keep in mind that if you get the less-expensive Ohaus model 750S scale without tare beam and want one of the Ohaus weighing scoops, you will need the more expensive model that includes a counterweight to compensate for the weight of the scoop. More importantly, that counterweight will take up one of the pegs on the end of the balance beam, severely compromising your ability to use the accessory weight set. There’s no point in getting an Ohaus triple-beam balance unless you get the model 760 with tare beam.

Scales for the Clay Studio (continued from previous page)

Ohaus offers the compact CS series of digital gram scales.

The CS5000 for about $90 has a capacity of 5000 grams, but is only accurate within 2 grams. That’s inconsequential if you are weighing 2500 grams of potash feldspar, but of concern when weighing 15 grams of red copper oxide or cobalt carbonate. The CS200 for about $80 is accurate to 0.1 grams, but only weighs a maximum of 200 grams. For the discerning glaze-mixer, I suppose it would make sense to have both.

The Acculab Econ series does a little better. The EC-211 for around $42 has a capacity of 210 grams and an accuracy of 0.1 grams, while their model EC-4100 for $62 has a capacity of 4100 grams and an accuracy of 1.0 grams, which is quite a bit better than the Ohaus model mentioned above.

Electronic Digital Counting Scales All of the electronic scales mentioned earlier will allow you to zero the weight of an empty container, but beyond that they just read the weight of whatever you add to the platform. If you want the full capability of the mechanical triple-beam balance, where you can set the weight and then add material until the set weight is reached, you’ll need to move into the more expensive category of “counting scales,” which generally cost at least $200. For example, the Citizen® brand CKG-series digital counting scales feature an audible alarm that goes off when you reach a preset weight. Most of the counting scales will keep track of multiple weights in sequence in order to determine an accumulated total. Many even have computer and printer connections (although I am not sure how we would use those features in the glaze lab).

Electronic Digital Scales for Clay Mixing For weighing larger quantities of materials when mixing clay, the new electronic balances have great advantages over the old mechanical bench scales, and the prices are reasonable. I like the Ohaus SD75 digital bench scale for around $125, with a capacity of 165 lbs. and 0.1-lb. accuracy. It has a sturdy, low-profile weighing platform connected by coiled stretch cord to a digital readout that can be mounted on the wall. As you can see from the image below, the digital readout can be out of harm’s way and won’t get obscured by spilled materials when the weighing platform is placed on the floor to handle bags and buckets.

CLAYTIMES·COM n SPRING 2010

When you move into the realm of the counting scales, you also get greater accuracy. The Citizen® CKG-6 counting scale for $240 (pictured above) has a capacity of 6000 grams and an accuracy of 0.2 grams, which is a very generous capacity and enough accuracy for anything we normally encounter in the studio glaze lab. If I were buying a digital glaze-lab scale, this is the one I would get—but I must admit, I’m still stuck on the triple beam balance. [

If you’d rather have a self-contained unit, the Ohaus C11P75 has the same capacity and price, but it has the digital readout located at the edge of the weighing platform. For those who weigh out serious amounts of clay materials, the Ohaus SD200 for around $150 has a capacity of 440 lbs.

The Slurry Bucket Slurry & Glaze Recycling Options Everyone has some way to deal with glaze and clay slurry so it does not go down the drain. Me? I have a 5-gallon plastic bucket in my sink that has 10½" holes spaced around the bucket about 4" down from the top. All my water and whatever is in the water goes into that bucket. The heavier components settle out, and the water on the top flows out the holes.

If I am going to throw a large quantity of liquid waste in the bucket, I tip the 5-gallon bucket first and drain the liquid down to the solid, then toss in the liquid waste. Things settle out quickly.

A second big advantage of always having that nearly-full bucket of water sitting in the sink is that I always have standing water to rinse out my glaze-holding yogurt cups, squeeze bulbs, and paintbrushes. I give them a swish in the standing water and don’t have to turn on the faucet. That bucket saves the drain, saves me time, and saves water, too.

I am not a prodigious maker, as my pots are time- and labor-intensive. I don’t empty the sink bucket more than three times a year.

When I do, I decant the water and the clay slurry goes into the dumpster. Perhaps it’s not the perfect eco-friendly solution, but it works well for me. And in 15 years, my drains have never stopped up!

Reclaiming Clay I have found that using a pre-stretched artist canvas provides a great surface for drying clay. Initially, I put a 16" x 20" canvas over a 5-gallon bucket—it catches any drips and still allows for air circulation. As the clay becomes drier, I place the ends between two buckets, increasing the air circulation. It’s light enough to move about the studio, and provides an easy-to-clean, well-ventilated, plaster-free drying surface.

Is it safe to use them in your studio?

Y

esterday, a friend showed me a very old kiln she wants to rehabilitate.

It was hexagonal, had about a cubic yard of interior space, and was wired for 110 volts. The brick was still in pretty good condition, but the electrical plug had only two prongs, which meant there is no ground wire. Technically, it is illegal to use this kiln in a school or any pottery where there are employees since it does not meet the Occupational Safety and Health Administration (OSHA) electrical standards. Unfortunately, OSHA has no jurisdiction over my friend who works alone in her own small pottery.

This old kiln’s electrical cord was frayed and there was asbestos insulation under the cloth sheath.

There also was an asbestos board behind the connectors on the control panel. The kiln could be rewired, but to do this legally would require the services of someone certified to abate asbestos. I suppose, since my friend works alone, no one would know if she did it herself. But she would be exposed to asbestos. So I told her about these risks.

Asbestos Diseases

Large exposures to asbestos dust can lead to asbestosis or a type of fibrosis somewhat similar to

Another type of cancer that is caused almost exclusively by asbestos is malignant mesothelioma. This cancer occurs in the membrane that surrounds the lungs, the heart, or the intestinal tract. It develops 20 to 40 years after the exposure and it is always fatal. It is called a “marker” cancer because it is so unique that when it occurs in a population, it tells researchers that there must be a source of exposure to asbestos involved somewhere.

Not everyone exposed to asbestos dies of one of these cancers.

I can even make this personal, because I’ve been exposed and I’m still here. I did get an expert to read my lung x-rays and found I have a small amount of pleural plaque that is often seen in people who have been exposed to asbestos, and some lung fibrosis (scar tissue), which is consistent with silica and asbestos exposure. That is, this article about asbestos can apply to me, as well.

Other Asbestos Kiln Elements Some of these old kilns also have asbestos insulation in the form of a woven gasket around

the door and asbestos insulation between the brick and the metal shielding on the outside of the kiln. This insulation was the cause of students being kept out of their school for a week sometime around 1990.

In this case, a principal in a New Jersey high school was told he would have to call a hazardous waste company to dispose of an old ceramic kiln. He found that this would be very expensive. So he “hired” two of his students to use metal saws to cut the kiln up on a Saturday after hours and just put the pieces quietly into a dumpster. After this was done, somebody squealed on the principal. I believe it was the parents of one of the boys who cut up the kiln.

As a result, the New Jersey State Health Department inspectors who enforce the state’s Public Employees OSHA (PEOSHA) showed up and tested the dust in the school and in the ventilation system. It was found that when the kiln was being dismantled, the ventilation system was still on. The asbestos had gotten all through the ducts. A school-wide professional abatement costing just over $150,000 was done, and the school had to be closed for a week.

What bothers me most about this story is that if no one had alerted officials, everyone in that school would have been regularly exposed to asbestos. The fine asbestos dust on surfaces and in the ventilation ducts would have been circulating in that school for years.

Asbestos in Schools I wonder how many other kilns, over the years, were improperly exposed in schools and universities. Let’s not just pick on kilns—there were many other sources of asbestos in schools.

So if, as I believe, schools 20 to 40 years ago were doing a rotten job of dealing with asbestos, shouldn’t we see a peak in mesothelioma cases in teachers?

To answer this question, we first need to know that in the absence of asbestos, mesothelioma is an extremely rare disease occurring in about one person in 1 million. So the statistics in the United States indicating that there are 14 mesothelioma deaths per million people indicates that asbestos exposure in general in the United States in the past was significant.

In April of 2009, the Centers for Disease Control published a study by the National Institute for Occupational Safety and Health (NIOSH) which analyzed annual multiple-cause-of-death records for 1999-2005.* These are the most recent years for which complete data is available. In those 6 years, a total of 18,068 deaths of persons with malignant mesothelioma were reported.

Next, NIOSH calculated the proportionate mortality ratios (PMRs) found for certain professions. PMRs are the fraction of all deaths from a given cause in the study populations (in this case, various professions) divided by the same fraction from a standard population. As a continued on next page

One of the most important facts about asbestos is that there are no symptoms after you have inhaled asbestos. There is also no treatment or cure once the asbestos has been inhaled.

The diseases it causes arise years later.

silicosis, the disease caused by inhaling clay dust that contains silica. Smaller amounts of asbestos can cause lung cancer.

Since some of the asbestos dust we inhale is raised by the lung’s clearing mechanisms and swallowed, several types of stomach and intestinal cancers are also linked to asbestos.

result, certain professions were found to have a higher rate of mesothelioma than that of the general population. Of the 163 occupations reported, five professions were found to have significant PMRs: plumbers; pipe and steamfitters; mechanical engineers; electricians; and ... elementary school teachers!

This means that in order for these teachers to die between 1999 and 2005, their asbestos exposures had to have occurred mainly from 1965 to 1985. Well, bingo! I was a practicing potter, teacher, and industrial hygienist consulting with schools between 1965 and 1985. So I can tell you that there were three major factors affecting exposure during this period of time: 1. Elementary schools were often in old buildings containing many sources of asbestos-containing building materials. Bad maintenance practices contributed to exposure such as yearly resurfacing and buffing of asbestos vinyl floor tiles and failure to repair damaged pipe insulation.

2. In the early years of asbestos abatement, the containment regulations were not always followed. Abuse of the asbestos regulations was sometimes flagrant.

CLAYTIMES·COM n SPRING 2010

3. There were many sources of asbestos in elementary school art materials. For example, Milton Bradley’s instant paper maché, contained 80% chrysotile asbestos powder. This was not evident to teachers because the ingredients were not listed on the plastic bag and the label carried the AP (Approved Product) nontoxic seal

on it from the organization known today as the Arts & Creative Materials Institute!

Years ago, asbestos was an accepted and common art material ingredient in this time period. For example, the “Art for Elementary School” booklet published by the University of the State of New York’s State Education Department in Albany in 1967 includes the following [unsafe] recipe for a modeling material: • 3 cups ground asbestos or asbestos shorts (used for covering furnace pipes) • 1 teaspoon Glue • 1 cup flour • Water Add enough water to make a dough of the right consistence for modeling. Ground asbestos is very inexpensive. When dry, it is light in weight, durable, a light gray color, and may be painted with powder paints.

The booklet also suggested zonalite and vermiculite be used in projects. As early as 1970, we knew that these minerals were contaminated with significant amounts of asbestos, too. But I was still finding this booklet in the state’s elementary schools until the mid-1980s.

The issue of asbestos-containing ceramic materials is personal. I have written in previous Clay Times columns that certain ceramic talcs contain asbestos. I’m now getting ready to testify in the third and latest case filed against RT Vanderbilt Company, which mined the talc. This suit is for the estate of a teacher who taught ceramics to disabled children in the 1970s, and who died of mesothelioma October 12, 2008, two days after her 58th birthday.

I

n the daily loop of ceramic trial and error, the potter’s eye develops a knack for dividing a process into steps, and recognizing recurring patterns.

Since my energy is now divided between making and teaching, I have found that skill as useful in the classroom as it is in the studio.

In the same way that I have learned to predict the half-dozen ways a beginner’s pots are likely to go haywire on the wheelhead, I have worked out the predictable advantages and pitfalls for each stage of learning, whether for beginners, intermediate potters, or advanced students.

Most of my beginner students are in my classes at the community college. While I have some art majors who are preparing to transfer to other colleges, majors range from culinary school to dental assisting, fire fighting to welding to interior design. Except for a few kids who are home from too much partying at Big State U and trying to salvage their GPAs, my students have real-life work experience and an appreciation for the value of their time and money. Many have kids to support and full-time jobs in addition to their studies. I have bartenders, displaced auto and construction workers, an exotic dancer, military personnel just returned from the fighting, recently single moms training for higher-paying jobs, hairdressers, and truck drivers.

My beginners, like my kids, have a rare opportunity to take on a challenge with no preconceptions of how it “should” turn out. They try wild ideas and impractical designs with sometimes stunning results. They have no struggle to think outside the established box, because they have never seen the box. It’s all new.

Instruction for beginning throwers is fairly straightforward, as beginner pots have the same recognizable falterings. It’s quite objective. Even my own kids, who have helped me unload many a student kiln, can groan at the weight of a chunky pot and say, “That’s a beginner!” Powerpoints, bisected pot post-mortems, and assessment of my collection of orphaned beginner clunkers make clear the goal and the hurdles.

The students learn to recognize the predictable elements of their early pots: square, bottom-heavy forms with V-shaped interiors; walls that collapse at that too-thin midsection; bowls with beginner’s bumps; tentative trim jobs; dumpy oneto-one ratios; and unplanned, toosharp rims that say, “This is where I ran out of clay.” Slab and coil pots have their lists of foibles, as well.

Critiques are direct and painless.

They want a good grade, and while they care about the pots

they spent so many hours on, their identities and self-esteem come from elsewhere. While most beginner pots look alike, I find that when my students learn to eliminate problems on the list, their own personalities begin to come through. Eventually, their pots stand on the critique table with something like an identifiable style.

My students at the potter’s guild, on the other hand, are working at a more intermediate level. While I do get newbies, half my class consists of juried guild members.

Some have been students for longer than the eight years I have been teaching there, and seem as much a part of the place as the mop bucket and wheels. Their skills are well beyond those in a community college class, and these folks have learned not just how to make a pot, but which pots seem worth making. They have trained their eyes with history books and ceramics magazines, and look at pots with a spirit of inquiry and assessment.

At this level, though, students are a bit more emotionally invested in their work. The more that intentionality and decisionmaking goes into design, the harder it is to step back and coolly reflect on its success or failure.

These are not college students, and I hand out no grades. Assignments are just suggestions, and critiques are by request only. Over the years I have identified the ones looking for serious feedback, and the ones who require kid gloves and lots of pats on the back with every “suggestion.” Those who are not up to critique are often subtly placed within earshot when I point out similar problems in a braver student’s work. While these potters are not egotistical navel-

BY KELLY SAVINO gazers by any means, they fight (as we all do) for balance between being satisfied with their work, and being frustrated with the distance between vision and final product.

The problematic temptation for intermediate students is the eagerness to imitate. The latest magazine cover, or the work of the most recent workshop attended, can certainly provide inspiration, and trying to reproduce work we appreciate can be a useful exercise and “stretch.” The danger, though, is to lose sight of your own valid ideas, your own style and skills, while accepting anyone’s pots as better and more worth making than your own. I have seen too many potters reject the laborious search for their own “voice” and satisfy themselves with making poor imitations of other people’s “officially sanctioned” good work.

Originality and an adventurous approach seem to become more elusive as skill level rises.

Potters working in community studios may find that their work is better than that of their peers, thus they have a hard time getting critical feedback.

Others work in isolation, and miss the outside perception of their work. If beginner students make fresh work and intermediate students can make derivative work, the curse of an advanced student is the tendency to imitate themselves, repeating their successes until they are caught in a loop with little freshness or originality.

They want to get their money’s worth from their tuition dollars, and have a “git ’er done” approach to coursework. This is no MFA program, and there is no melodramatic hand-wringing about artistic identity. While they will learn the language of 3-D design and the vocabulary of

process and critique, there will be no artspeak in these classes. The goal is to train hands and learn the materials, forming in clay the pots they have designed in their sketchbooks. It is as natural a process as learning to tie shoes or ride a bike (and equally impossible to teach someone by just talking about it). They see it, try it, fail, and revise. They have persistence in their favor, and a complete lack of “artist ego.”

Originality & Destiny

49

Originality & Destiny (continued from previous page) The pitfall for advanced students is that they find success, acclaim, gallery sales, and some notoriety, and then begin to work in an increasingly smaller circle, focusing on their “signature work.” This is certainly not unique to our medium ... the wider a potter’s fame, the more firmly the public would like to keep that potter making the stuff they like. Ask any famous musician who has launched a passionate exploration into new and different music, only to face the fans in concert shouting requests for greatest hits from a decade ago. A lot of us would be distressed if Rimas Visgirda gave up his angular profiles, Ron Meyer quit scratching his sinister critters, or Jack Troy switched from wood-firing to cone 6 oxidation. It’s not an easy dilemma.

A few advanced students come to my studio for private lessons, looking for a new challenge and some straightforward critiques. Since I have no business dictating aesthetics and vision for someone else’s work, I confine my feedback to clear technical issues, details of craftsmanship, and design problems. Critique time with advanced students is largely about guiding their own self-assessment, with pointed questions and a subtle trail of bread crumbs.

My best trick for getting established potters “unstuck” is to put them back in the shoes of my community college students, by challenging them to take on some aspect of clay that they have never tried before, or have failed at in the past and abandoned. Their very best work gets set aside for a while, as they fumble with beginner hands at areas they have never explored.

That is the value of instruction: teachers make us do the things we don’t want to do, and often that’s where growth lies. The wider challenge for the individual potter is to be your own coach: resist the temptation to imitate yourself or others, have enough distance from your work to experiment with a beginner’s abandon, and be willing to start all over in some facet of ceramics that you have never considered “your area.” I’m in the lucky position, now, of heading into my studio inspired by what I have learned from the pots of gallery artists, potter’s guild “weekend warriors,” and an exotic dancer named “Destiny.” [ Kelly Savino can be reached via e-mail at: primalpotter@yahoo.com.
