My ThinFire shelf paper turned brown

Postby marykaynitchie » Tue Nov 03, 2009 9:58 am

Recent customer question:

Q: What would cause my thin fire shelf paper to burn? It turned brown. I had to shut off my kiln because it was burning.

A: Not to worry! At a certain temperature, (maybe 500-600 degrees F) the actual PAPER part of the ThinFire will turn brown, then flame up and burn out. This is totally normal. What is left behind after the firing is over is the white ceramic binder. The paper part is just the carrier for the ceramic binder. Go ahead and fire up your kiln again. The phase where the paper turns brown is 100% normal, temporary, and will not hurt anything.
