Pure antimony metal is silver gray/white and brittle.
Although actually a metal, like germanium and tellurium (of which more in forthcoming articles), antimony is also termed a metalloid. (A metalloid displays the characteristics of both a metal and a nonmetal.) In addition, it has four allotropes (see Gallium: A Slippery Metal), of which two (yellow antimony and black antimony) are neither stable nor metallic. Indeed, yellow antimony, which only occurs at temperatures below -80°C, is extremely explosive.
Antimony has been known of, and used, from at least the third millennium BCE. Back then it was used, amongst other things, in eye shadow (kohl) and for medicinal purposes. (More recently it has been used in the treatment of bilharzia (schistosomiasis), a particularly nasty disease caused by parasitic worms that can spread throughout most of your body.) Antimony and its compounds can, however, be particularly toxic.
