Hot glass will adhere to kiln shelves if not prevented by a separator. For most basic kilnforming projects, Bullseye Shelf Primer is an ideal separator. It’s affordable, highly effective, and easy to use.
See Using Bullseye Shelf Primer for instructions.
For some projects, you may wish to use ThinFire Shelf Paper or Fiber Paper. To learn about using ThinFire, you can read our Instructions for Using ThinFire Shelf Paper. To learn about using Fiber Paper, see TipSheet 3: Working Deep and TipSheet 5: Bullseye Box Casting.
Many of our video lessons also demonstrate how to use shelf separators.
