Why is my thin fire burning? After about 1/2 hour in the kiln the paper turns brown and starts smoking. This has happened 2 times.
I have used this kiln many times with no problems, always with thin fire. It is a used kiln and the kiln shelf looks like it has shelf primer on it. The kiln shelf looks in good shape, although it now has brown residue on it.
When I first started fusing I used some shelf paper that smoked and really smelled bad as it turned brown and burned of the binders. I use bullseye thinfire now and it doesn’t smell but yes it does turn brown before it goes white again – no brown resdue though.
