Description
1) A red pigment that is also called antimony vermilion. Antimony trisulfide was first synthesized in 1842 by C. Himly. Depending on conditions, the pigment can range in hue from orange to deep red. It is an unstable crystalline form and turns black when mixed with lead pigments. Antimony vermilion is also used to color ruby glass. See also Antimony oxide sulfide.
2) A black pigment that is prepared by grinding the mineral stibnite. Antimony sulfide, is actually antimony trisulfide, but because it exists as red (synthetic) and black (natural) crystals, the black form is sometimes called antimony sulfide and antimony black. Black antimony trisulfide is used in camouflage paints because it has the same infrared reflectance value as green foliage. The black powder, called kohl, was occasionally used as an eye paint in Egypt from the Amarna period onwards (Ogden 2000). Antimony black powder was used since the late 17th century to blacken the edges of books (Roberts and Etherington 1982).
