grog? in Smelting, Melting, Foundry, and Casting Posted July 22, 2017 Good Afternoon Guy's I have just made my first foundry from a used helium tank. I would like to know the best way to line it before I can start using it. I have seen a product called "Grog" which appears to be crushed fire bricks, my question is how do I use it ?
