Fiber Paper, 1/32″ Ceramic fiber products have many uses because they reflect heat rather that than absorbing it. They are useful in controlling the shape and flow of hot glass in a kiln in ways other materials can not. Fiber Paper can be placed on a kiln shelf instead of kiln wash. Fiber Blanket can be shaped for use as a slumping mold. These useful and versatile products do have one drawback, breathing the free fibers presents a health hazard. Always use an OSHA approved respirator whenever this material is being used. We have two sizes; 1/32″ X 12″ X 24″ and 1/32″ X 24″ X 24″.
