Dear Robert;
A typical load weighs 506.8#s total. 220#s for shelves, 100.8#s for
posts, and 186#s for wares(retail worth $1760).
The weight of the fiber lining is 368#s, the floor refractories weigh
300#s. That is it for now.
My electric bisque kiln is 3" thick, 8 cuft volume. No idea how much
to fire. Typically two glaze loads in each bisque.
Cheers, Hank
