Bismuth

The name bismuth is derived from German, and has gone under a few alterations from its original form. Originally known as "weisse masse" and probably referring to bismuth oxychloride, it was then turned into "wismuth" then to "bisemutum," the latter of which led to the modern word. Bismuth is a brittle metal with a relatively low melting point, at least as metals go, and as such generally isn't used in its pure form, but alloyed with other metals. It can be found naturally occuring by itself, or in the form of the mineral bismuthinite (Bi2S3). Commercially, bismuth is used in nail polishes, and is sometimes used in automatic fire-sprinkler systems when alloyed with cadmium, which together has a melting point at about 70 °C.
