Description
A bright yellow, crystalline powder that occurs naturally as the mineral orpiment. Orpiment is often found with lead and silver ores along with realgar (arsenic disulfide). It was once widely used as a pigment because of its bright rich color. However, it is extremely toxic which has limited its use and availability. Arsenic trisulfide was also used to dehair and tan leathers, to kill rodents, and to print calico textiles. It is still used in fireworks and in the manufacture of infrared transmitting glass.
Synonyms and Related Terms
arsenic (III) sulfide; Pigment Yellow 39; CI 77085, 77086; orpiment (mineral); arsenic sulphide (Br.); Operment (Deut.); Rauschgelb (Deut.); Konigsgelb (Deut.); jaune royal (Fr.); trisulfure d'arsenic (Fr.); oropimente (Esp.); orpimento (It.); trisolfuro d'arsenico (It.); kio (Jap.); sekio (Jap.); ouropigmento (Port.); yellow arsenic sulfide; king's yellow; arsenic yellow; jaune royal; king's gold; arsenous sulfide; arsenic tersulfide; arsenious sulfide; auripigment
