Tin-glazed earthenware
MFA Acc. #: 2000.708

Description

A bluish-white, brittle metallic element. Antimony occurs in the ores stibnite, kermasite, tetrahedrite, livingstone, and jamisonite. It is mined in China, Mexico, Canada and Bolivia. Antimony, originally called stibium, was first described in 1450 by Tholde (Basil Valentine). As a metal, antimony is hard and shiny but neither malleable or ductile. Antimony does not tarnish in dry air and tarnishes slowly in moist air. Antimony is used in the manufacture of alloys, such as Britannia metal and Babbitt metal. It is also used for bullets, fireworks and as decorative metal coatings. Antimony has been found in trace amounts in ancient Copper and Lead alloys. Pure antimony can be found in the metallic form and in two allotropic forms, as yellow crystals and as a black powder. The black powder, as well as the orange antimony sulfide, was occasionally used as a cosmetic in Egypt from the Amarna period onwards.

Stibnite

Synonyms and Related Terms

Sb; stibium; antimoon (Ned.); antimoine (Fr.); Antimon (Ces., Deut., Nor., Sven.); antimonio (It., Esp.); Antimônio (Port.); antimony black; antimony regulus; CI 77050

Risks

Inhalation and contact with dust and fumes can cause irritation. Antimony will react with hydrogen to form highly toxic stibine.

Combustible. Black antimony is explosive in air. Salts are highly toxic.
