Laser-cut, vacuum sealed packs of lab quality 4.5N bismuth block, weighting 1.14 pounds on average per block.

• It has a low melting temperature making it perfect for DIY casting projects and alloying.
• With some practice, you can make beautiful hopper crystals by melting it.
• It is the most diamagnetic naturally occurring element (repels magnetic fields).
• It has one of the lowest thermal conductivity values among metals.
• It expands upon solidification like ice from water, and can be used to make a tight-fiting casting such as typesetting.
• It 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.
