On Friday at four pm the little ceramic projects came out of the kiln, at Finger lakes Community College. I am an adult learner art student, embarking on an adventure in ceramics, in case you are new to my blog.
I was interested to learn that the kiln has to run at a very high temp--1600F or so for 24 hrs to change the chemical composition of the pots so that they are no longer "greenware". I am unsure of the exact temperature, but fortunately the temperature can be monitored and the professor can control it via a computer. There are different types of ceramic ware. There is earthenware, stoneware and porcelain, and all require a different temperature for firing. We are working with stone ware. My pine pot and the little bears came out of their second firing, post glazing. I have yet to see how they came out. But here is the prior to the second firing photo. Tomorrow, on Sunday, I am going to go in to work on my coil projects and I intend to check on the pinch pots.
Pinch projects prior to glaze application: "bisque ware"

I applied a coat of blackish copper oxide on this also to darken it.
These are the glazes.
Update on pinch pots one year later!
