Hi everyone, did a lot of reading on this forum, first post.
I am building a gas "forge" out of a 6 gal steel pail and decided to go with 2x 1" inswool insulation. Now I am considering refractory layers and a rigidizer. I have Satanite, Plistix 600F and ITC-100H. The order I am thinking of going with is (starting from outside to inside): Steel wall, 1/8" satanite, 1" inswool, 1/8" ITC-100H, 1" inswool, 1/8" Plistix 600F. "Buttering" each application. Looking for advice on better order, replacement of materials, etc., and reasons why.
Also have a question on whether I should spray paint the inside of the steel walls (before applying anything) with heat resistant paint (Rust-Oleum 248903). The reason I am thinking it would be a good idea is because I want to prevent any kind of rusting, especially given that the first application of satanite would bring water in contact with the steel surface.
I am planning to melt aluminum, brass, maybe silver and at most copper so I am not planning on having anything over 1100 C in the crucible.
Thanks in advance!
