Diving belt weights for casting
I recently came across a couple of diving belts at the scrap yard. The big weights were marked 7lb and 8lb look like wheel weight lead but not sure. The other weights are rubber coated. I cut off the rubber on one, very shiny looking. I melted it down and i think it might be zink. Does anyone have any idea what these weights are made of, and how can I tell.
