Bismuth crystals: Bismuth is a chemical element that obtains iridescent hues when exposed to air.while its chemically similar to lead, it has an unusually low level of toxicity, making it an ideal replacement.
Bismuth Is a Chemical Element With An Amazing Iridescent Oxide Surface Bismuth is a chemical element with symbol Bi and atomic number Bismuth, a pentavalent post-transition metal, chemically resembles arsenic and antimony.
Bismuth Crystals close-up of a small group of bismuth crystals, 15 mm wide, perched on solid bismuth. The crystals get their colours from a thin layer of bismuth oxide. Diffuse lighting is necessary to get the best out of these colours.
I could start a board just for this amazing stuff : BISMUTH! Bismuth Crystals, naturally occur like this after it's initial form is heated to a liquid state and then cools to form this geometric pattern!
