  • Quick and cheap aluminum melting furnace setup

    I made one with a thicker concrete crucible and it didn't work. for a couple of hours it withstood the heat from a large bag of charcoal and a lid to trap the heat. mail came at that time and i threw the junk mail in and in a couple of seconds the junk mail burst into flames. i think my problem was a thick concrete crucible. will use an old fire extinguisher next time.
