A brittle, silvery-white metallic element used in alloys, flame retardants, and semiconductors. Historically, antimony compounds were used in cosmetics, medicine, and alchemy.
From Arabic al-ithmid, referring to a mineral form of antimony sulfide used as eye makeup and medicine. The word passed through Medieval Latin as antimonium, then into Old French and Middle English by the 15th century. The Arabic term reflects the metal's early use in Islamic medicine and cosmetics, particularly as kohl for eye makeup.
Antimony was literally a beauty product before it became an industrial metal - Arabic women used it as eyeliner thousands of years before modern cosmetics! The same element that now goes into flame retardants and electronics once adorned the eyes of ancient queens.
