Fire coat on castings

I developed the anti fire coat (fire scale) technique several years
ago. It works for me. However, when casting, what works for one may
not work for another. I entered a summary of the procedure on july
28, 2001 article 00927. It costs nothing except scrap wax. Give it
a try and let me know how it works. -
