[TheForge] crucible furnace

[Michael]

The Kaowool with ITC #100 will certainly take any heat source that a
home-made bottom refractory will, especially if you buy some rigidizer and
stiffen the inside face to about 1/2" depth before using the ITC #100
coating. Otherwise, you will have trouble, not on the vertical portion, but
the overhead and exit hole. You will find the furnace to be surprisingly
efficient this way.
