Art Chowder November | December, Issue 24 | Page 24

T he Venn diagram of art and science in this process is blatant and venerable. I got to chat with Gina a little bit in her studio and she showed me shelves and shelves of her glazed ceramic art, the glaze coming from different styles and combinations of ash and chemicals… she tries her best to explain to me, most of it flying over my head. “This glaze will go red. This is a shino glaze — it’s got a lot of salt in it — you can tell it’s got salt by the crystallizations. Mix it all up … and so that surface that you’re seeing on all those pots down there comes out of a bucket that looks like this. And the ingredients in this are usually a couple clay bodies; there’s probably some soda ash in this glaze, and then something to stabilize it. I’d have to look at my recipe. I’m testing one this time and it has the flux, the clay, the stabilizer, and then this is just meant to keep the glaze from separating out. I put a bunch of these in the kiln this time to test to see what they’re going to do.” I remark with awe that she seems to have a great handle on the science; she’s showing me a row of notebooks with notes about chemicals, dates, temperatures, observations … but she says she looks at it more like a cookbook. “I see recipes that I have tried. And then this is what we do during a firing, too — ” she shows me a specific notebook “ — this is a firing log: ‘Gas on all day to keep warm; closed it up at three; put the gas on barely; turned it up; 0-12 is going down…’” (this last part is referring to a small cone-like object called a “pyrometer” which indicates rising temperatures as it melts). And then I can refer back and say ‘Oh last time it did this and this and this, you may need to close it down a little bit more or open it up a little bit more, so you reference this.’ They’ll do the same thing on that kiln out there.” 24 ART CHOWDER MAGAZINE They’ll spend four days of coaxing the flame as close to 2250 degrees Fahrenheit as possible, and then they will let the entire structure and its contents cool for about five days before opening the door and gazing like archaeologists in on their transformed treasures, as Dennis Smith puts it. Until then all senses are engaged as the artists/engineers/ anthropologists split wood, notate temperatures, and make observations and comparisons between the progress of this firing versus previous firings. The smell of woodsmoke hangs grandfatherly in the air; crickets are chirping unobtrusively in the marsh nearby, and though the nights are still chilly the kiln radiates warmth, especially when the small door is opened for not more than four seconds at a time to feed the flame. They check the thermometer obsessively, raising their eyebrows in anticipation and hopes of faster heat. Conversations I barely comprehend go by … a what cycle…?
