Bismuth, the woman said, it casts really well and it's a lot less toxic than lead. I left the shop with a bag of that as well. Bismuth is without doubt a heavy metal; It occurs so low in the periodic table many were puzzled by the fact that it didn't seem radioactive. In fact its major isotope bismuth-219 was predicted to be so back in 1949.
