Made from the same reliable formula as our regular high alumina shelves, these shelves are also rated for cone 10 but are 35% lighter. The extrusion process provides a kiln shelf with a core I-beam construction for strength and rigidity, but at a much lighter weight than regular kiln shelves.
These shelves are not round, but are cut multi sided to match the number of sides of your kiln. Available in 20" diameter full and half shelves for 23" diameter kilns, and 25.5" diameter half shelves for 28" diameter kilns, these shelves are still 3/4" thick so they will match your existing kiln furniture.
Please note: there is no warranty on refractories! There are many factors that can cause shelves to fail over which we have no control. It is the nature of the material. Other than shipping damages, no claims can be made on refractories.
