Hi, Have sent my message off to you and forgot to mention the way I gloss
fire. Could be a part of the problem? Please read this message with the
fuller one. I fire up normally, slow to 400oC and then turn it up to full. I
let the kiln cool on it's own to 250 to 200oC before I pull the bungs out.
Thanks again. Lyn
