Product: Bismuth Crystal Specimen Decoration Mineral Earth Science Minerals Collection Bismuth Crystal Samples Christmas Gift (Cabinet) Bismuth is one of the few materials that have a greater density as a liquid than as a solid.
Only a few other materials such as water, gallium and germanium, exhibit this property.
The trigonal crystal structure accounts for the cubic formations.
The iridescent rainbows of colors observed are caused by light scattering off thin
layers of bismuth oxide formed when the surface of the hot bismuth reacts with the air.
Great for teaching about crystals, states of matter or even as a gift!

Product: 8 Pounds of 99.99% Pure Bismuth Metal - Unique Metals You will receive a box containing 8 pounds of bismuth chunks. It will arrive in multiple pieces. Bismuth metal is great for element collectors, crystal makers or any one who has a use for a low melting temperature metal. It is a non toxic metal with symbol Bi and atomic number 83 Element 83 has quite the repertoire of unique features: Low melting temperature making it perfect for DIY casting projects and alloying. With some practice, you can make beautiful hopper crystals. The most diamagnetic element (repels magnetic fields). Has one of the lowest thermal conductivity values among metals. Expands upon solidification like ice from water, and can be used to make a tight-fiting casting such as typesetting. Makes an excellent lead substitute due to being non toxic, although you should still wear protection when handling it. In earth's crust, it is twice as rare as palladium and only twice as abundant as platinum and gold. Increased phase-out of lead in manufacturing means demand for Bismuth (and its price) will skyrocket - it's only a matter of time. Bi is very brittle so expect some crumbling during shipping. We always strive to provide the biggest chunks possible. 99.99% Pure
