ok, i admit to, and learned from making a nasty mistake of smelting in my casting pot. i do not want to do that again. it was a nasty mess to clean the pot out enough to cast from. anyway, i have read here several times about people using a cast iron melting pot over a turkey roaster. i do not have a turkey roaster, but i was thinking my propane coleman stove might work ok to heat with. i have no idea where to find a cast iron pot though. would a large cast iron frying pan work ok? in either case, do i have to "season" the cast iron like you do to cook food with one?
