Lava Cloth is an exciting product, which provides glass artists with an opportunity to apply a unique textured finish to the backside of their work thus giving a finished appearance and not the mundane appearance, which is normal from a standard kiln shelf. Lava Cloth is 100% American Made, including all components, providing the highest possible quality.
Lava Cloth kiln shelf linen is rated for use at temperatures up to 1800°F. The useful life of Lava Cloth will vary among individual artists. In test firings the cloth was fired 12 times at 1350 and 1450°F with a soak time of 15 minutes before starting to break down. It begins to turn fuzzy as it breaks down.
Lava Cloth does shrink with the first firing. A 12” square will shrink to an 11-3/8” square. You will need to put some sort of weight on the edges of the Lava Cloth to hold it in place.
