Micro Kiln Accessories - 2 Sheets of Kiln Safe Fiber Paper - 5" Square - 1/8" Thick - Perfect For Mini Kilns Fiber paper is a favorite among warm glass artisans because it does not disintegrate in the kiln! This package contains 2 sheets 5" SQ. Kiln paper provides a nice, textured bottom to your finished fused glass piece or to leave holes open in fused glass jewelry pieces! Can be used to line stainless steel rings for pot melts, to line kiln shelves instead of using kiln paper and so on. Once the finished piece is fired and cooled, fiber paper can be peeled away and discarded, or if used to line a kiln shelf, used again! Again, fiber paper does leave a texture on the side of the piece it comes in contact with during firing. The depth of the texture left behind depends upon the thickness of the paper.
