Can the shelf inside a glass kiln be placed directly on the firebrick bottom?
Because the kiln shelf is a heavy thermal mass, it takes longer to heat up than the air around it and the glass on top of it. Placing the shelf directly on the kiln bottom makes the shelf more difficult to heat. This is why we recommend placing 1/2” posts under the shelf. The posts allow better heat circulation under the shelf.
