I found this at the beach by metal detector. Doesn't seem to be magnetic. Could anyone identify what it could be?
Yeah, will try! Thanks for advice!Could be a piece of asphalt,like from a parking lot.Put it in a container of mineral spirits,also known as paint thinner.if it dissolves or the thinner turns black it,s probably asphalt.Doesn,t have to be a large container,just a little more than enough to cover the piece.Hope this helps.
