I come across molten aluminum frequently; I suppose it is from old campfires where cans were just tossed into the fire. Lead also appears at times but am stumped with the latest find. It is non-ferrous, dull dark gray in appearance, very hard, very heavy, smooth on one side and rough on the other, oval in shape and can be scratched (with difficulty) to a very bright metallic finish.
anyone with ideas?
