Advancer Silicon Carbide Kiln Shelf - 21" Half 10-Sided, 5/16" Thick

Advancer Kiln Shelf 21" Half 10 Sided Nitride Bonded Silicon Carbide for 23" Top Loading kilns with 2.5" Brick Advancer Nitride Bonded Silicon Carbide Kiln Shelves Advancer kiln shelves are the strongest, lightest and thinnest kiln shelves in the world. They do not warp at high temperature. They are rated for use up to cone 16 ! These lightweight kiln shelves have less thermal mass, so you save energy in your kiln firing by spending fewer BTU's heating up your kiln furniture. Because they are so thin, you gain stacking space in your top loading kiln. With more efficient stacking your kiln yields more work every firing so they pay for them selves very quickly. They have close to zero porosity making cleanup a breeze. Kiln wash is still used if desired. The Advancer kiln shelves are recommended for gas, soda, and electric kilns. They can be used in the back stack of wood kilns but most people prefer conventional silicon carbide shelves for wood fired kilns. There are many shapes and sizes available including squares, rectangles, full and half multi-sided shelves.
