Hello all, wondering if you can help with a new problem. I’ve used the same earthenware body and brush on botz glaze for over a year no probs. I have an old sitter kiln and bisque to 03 then glaze at 05 this has worked till now... suddenly my pieces are crazing about a week or two after firing (not immediately). It’s shuddering for some reason. I am making slightly chunkier pieces, could this be why? Any ideas why this is now happening would be great!
