800-31338 Herringbone Lava Cloth

Lava Cloth is 100% American Made, including all components, providing the highest possible quality. Lava Cloth does not stick to glass, kiln shelves, kiln brick, or fiber board. Place Lava Cloth directly on the surface you wish to fire on, then place glass on the Lava Cloth and fuse. Lava Cloth is non-carcinogenic. Lava Cloth is a fiberglass product with the standard warnings for fiberglass materials. These warnings are: Contact with fibrous glass may cause temporary irritation. Wear long sleeve loose fitting clothing when handling any fiberglass material. Gloves and eye protection may be appropriate in certain applications. Wash with soap and warm water after handling. Wash work clothes separately and rinse out washer. A disposable mask designed for nuisance type dusts may be advisable when high dust levels are present. Lava Cloth is tan in color prior to firing, turning white after firing. On some occasions there may be an odor and may see white powder ( a silicon byproduct) on the kiln shelf with the first firing. These are non hazardous and the powder does not stick to glass. If your kiln has a glass view window you may see a white coating after several firings this simply wipes off. Artists using art glass usually achieve 10+ firings at 1350-1485° F. before the Lava Cloth starts to breakdown - it becomes fuzzy or simply breaks apart. Artists using float glass firing up to 1600°F. obtain about 5 - 6 firings before breakdown. Discard used Lava Cloth in regular trash when it no longer provides the finish you wish. There is NO messy or hazardous cleanup with Lava Cloth. When one side breaks down you may get 1-4 firings on the backside before it breaks down.
