Awesome. What is the diameter of the burner? If we have that to work with, this entire project gets about 2x cheaper :)
It looks like this place has all the clay and sand that we need:

50 pounds of the two clays (bentonite and fireclay) should be ample, 100 pounds of sand should match, and even might cover the mold-making.
Other than the cement and perlite, can come from home depot.
Anyone know any good places to find scrap steel bits. I typically hit metal-art stores dumpsters, and clippings from steel-yards.
