The listing, Bismuth!!From West Germany!! has ended.
This auction is for one good sized piece of Bismuth , lab made crystals for the collector or budding scientist, or just about anyone who like beautiful things! The crystal formation on this piece is quite amazing! Like little stairs in an M.C.Escher print! It varies from dark blues to metallic purple to and almost pink! It is considered to have the highest mass of any element that is stable! It's Chemical Element smybol is Bi , and it's atomic number is 83. The free element is 86% as dense as lead! It was discovered in 1753 by Claude Francois Geoffrey, although it has been used since ancient times. It was thought to be a form of tin or lead.(It is actually used now to replace lead in many things) It has a low toxicity for a heavy metal and compounds made from it are found in cosmetics and Pepto Bismal!! It decays with the half life of more than I BILLION times the AGE OF THE UNIVERSE!!Imagine that!! (I wish I was decaying at the same rate!! Lol!! ) It is quite a fascinating element!! You can read more about it on Wiki !! And you'll probably hear more about it as it's being used as a replacement for many things, especially in plumbing , where lead can no longer be used, bismuth is a much safer option.
