Duraboard is a rigid, high temperature board that can be used in place of a ceramic kiln shelf. It withstands temperatures up to 2300 degF. Duraboard saws easily, making it handy for fitting kiln interiors or for a drop-out mold. It contains an organic binder which burns off from 350-1000 degF. Requires no shelf primer if used at slumping or painting temperatures under 1200°F. Sheet size: 24" x 24". Coat both sides with alumina rigidizer hardener (recommended).

Kiln Liner is an easier and quicker way to prevent glass from sticking to your kiln shelf at full fusing temperatures. It reduces prep time since there is no need to use a primer. After firing is complete, Kiln Liner Fusing Release Paper can be disposed of easily because it does not break apart after firing like like other fusing release papers. Unlike primer, there is no need to scrape shelf clean or remove residue from the back side of your fused glass after firing. Kiln Liner Fusing Release Paper is porous, allowing air to circulate. This reduces the probability of air bubbles from forming between the glass and kiln shelf. Whether you are a hobbyist or professional artist, time is of the essence. Why waste time mixing, coating shelves and waiting for primer to dry when you can simply cut, insert and fire? Approximate paper thickness: .005" (.127 mm).

Thin shelf paper for fusing. Stands up to full fusing without charring. A heat resistant, lightweight ceramic impregnated paper, which provides an excellent separation between the kiln shelf and the glass in kiln firing applications up to 1600°F. Imparts a fine matte texture to fused glass pieces. Compared to conventional kiln washes, (alumina hydrate/kaolin clay mixes), thinfire reduces shelf preparation time and improves surface release quality.
