TitleBismuth in bismuth oxide, Tintic Mine, Utah
DescriptionBismuth is an ore of the element bismuth (Bi). Much of the poor quality bismuth specimens are artificially regrown to produce interestingly shaped hopper-like bismuth specimens. Bismuth has a very interesting property: similar to water, instead of contracting when it solidifies (like most other matter), it expands. This, and the fact that it is very diamagnetic, give it many uses in the electronic field. The samples shown are quite small; the largest is 2 mm across.
