Not Thin Fire or Fiber Paper

[wordana]

I have never seen fiber paper of any kind discolor a kiln shelf. I think you had some sort of chemical on the shelf, the paper, or the glass (oil of some sort?). When fiber paper or Thin Fire burns off, it smells like paper — not chemicals.

All “in my opinion/experience”,
