High Strength Silicon Carbide Kiln Shelves
1. Introduction
High Strength Silicon Carbide Kiln Shelves are thin, lightweight made from an advanced Nitride-bonded Silicon Carbide composition, stronger and weigh half or less compared with a conventional 1” thick Cordierite kiln shelves. They do not sag or warp after many firings under heavy loads and suitable for temperatures up to 2600°F and a great choice for Gas, Soda and firing kilns. They are about twice the cost of Cordierite or High Alumina kiln shelves cost.
Kiln shelves should be stored standing up on their edges. Storing them flat makes it more possible for them to break or cracks. Keep shelve dry. If they do get wet (e.g., after applying kiln wash), heat them slowly and soak for a few hours at 300° F.
Warning: Stay away from electric kiln elements – kiln wash will corrode and reduce the elements life expectancy.
