These are zinc anode balls of very high purity: 99.99% guaranteed. It's a far cry from the scrap roof flashing for which I still hold font memories. But let's face it, at less than a dollar a pound in bulk from a wholesale distributor, this stuff is much, much more pleasant to work with. It think it even tarnishes more slowly than impure zinc from the scrap yard. See below for one of the first things I made with this new source of high-purity zinc.
