[caption id="attachment_531" align="aligncenter" width="490" caption="thrown COPPRclay bowl"][/caption] I thought I'd post this picture, because back in October of 2009, I posted this bowl before I fired it.
Needless to say, it cracked and the spoon cracked, and I probably would not use the open firing schedule again for COPPRclay. Many items in that first firing cracked. The next batch I did, I used the schedule suggested for COPPRclay, in the carbon, in the stainless steel pan. Nothing cracked in the subsequent firing.
