[L, antimonium.] A metal of a bright bluish - white color and crystalline structure. When strongly heated it burns with a white flame, giving off the fumes of "flowers of antimony," a compound with oxygen. It is a bad conductor of heat and electricity. It does not rust or tarnish when exposed to the air at ordinary temperatures. This property, combined with its hardness, renders it of great service in the arts in the formation of alloys. Pewter, type metal, Britannia metal, are all alloys of antimony. The metal is generally prepared from the mineral stibnite, a compound of antimony and sulphur. This ore is found in France, Spain, Italy, Canada, Borneo, and Australia. It has been long used in Eastern countries for darkening the eyebrows. Tartar-emetic contains antimony, tartaric acid and potash.
