Home Docs Loading the Kiln

I’ve read that the light-weight silicon carbide shelves are bad for electric kilns.

Silicon carbide shelves are used mostly in gas kilns instead of electric ones because silicon carbide shelves can conduct electricity. But they do not damage electric kilns. They are lighter than cordierite shelves and more expensive. Before you use silicon carbide shelves, repair any element that bulges out of a groove. The elements must not contact the shelves.
