glass breaking in kiln--help??
Posted: Tue May 13, 2003 10:33 pm
I have a question about fusing glass and kilns..
I bought the new "bigger" (13" top loading) kiln and I keep having glass explode in it-- well not explode, but break up.
It's got the very same automatic controller as my little kiln so I (think) I know how to use it. I have tried going up slower, but that doesn't seem to work.
The only difference I can see is the ceramic shelf and the size of the Kiln. In the little kiln I fire for a full fuse to 1550 (if it's accurate). Might the big kiln be hotter for some reason and would that cause glass to break? The other thing is that the thin fire paper seems to break up (turn to dust) more in the big kiln whereas in the little kiln it stays in sort of delicate sheet consistency.
