It's not easy firing thin porcelain to a near state of melting, but the translucency and vitreous nature make it all worth the occasional loss. My last firing was just over cone ten (over 1280 deg. Celsius) not good, only two successful pieces from a whole kiln load. Cross fingers for the next firing.I think my elements in the electric kiln are getting tired/old. The Harco kiln sitter chucks a wobbly at 1240 deg. So from then on it's up by only about 25 deg. an hour. And a vigilant watch through the spy hole with my welders goggles to watch the cone fall over. I've got a collection of bent cones now. I think they'd make a wonderful "African" wild animal tooth necklace. Any takers?
