With this kiln I had two broken pieces (a plate and a mug). Both were glazed with COYOTE Gun Metal Green. I never had such experiences with this glaze. I fired it to a hot cone 6. What about you?
Georgies Scotch Pine always fails me. I have given up on this glaze. It sends to be too thick, and when it drys it always cracks. Then the result out of the kiln is splotchy.
