ThinFire Shelf Paper is intended for single use. Position it on the kiln shelf as you would any lightweight ceramic fiber material. A single layer will prevent molten glass from sticking to your shelf at temperatures up to 1600˚F (871˚C).
ThinFire is so lightweight that it is easily affected by glass movement and will sometimes pull into or curl over the glass perimeter at maximum firing temperature. Contact with the top surface of the glass will leave an undesirable haze. To prevent edge curl, weight the outer corners of the paper with small pieces of glass or bits of kiln shelf as needed.
*Remember the logo side is placed down onto your kiln shelf.
One package has 10 sheets of Bullseye ThinFire Shelf Paper.
Each sheet measures 20.5" x 20.5"
