Jared, Im not sure if the Tim Lively would work with propane..on a second note I've been reading about wood fired Pizza ovens, the reason I bring this up is they are taking smashed fire bricks and mixing with sand a cement to line the inside of the oven I would think you could do the same thing for a forge. the last time I was at the builder supply they gave me all the broken fire bricks as they can't sell them .
