1.I am building up a supply of aluminum to melt and was wondering if coffee cans are aluminum2Sources for cast iron? I don't want to buy any unless its scrap or somethingIt is also to melt(please don't leave answers telling me how foolish this is or anything, I've got it under control ;)3Is it necessary to add zinc to molten brass since it might vaporize?Thanks,ThE aSkEr
What about grains? I also suggest more dark leafy greens.
1) Most likely coffee cans do not contain any aluminumUse a magnet to tell for sureAluminum brass are non-magnetic, cast iron IS magnetic (brass is also obviously copper colored.) 2) Best way to get cast iron is from a junk yard or recyclerCans have impurities like coatings on the inside glue on the outside3) No, you don't need to add zinc to molten brass when melting.
