Description
A brilliant, transparent yellow pigment also known by the name cobalt yellow. Cobalt yellow is composed of potassium cobaltinitrite. It was discovered by N.W. Fischer in Germany in 1848. Cobalt yellow was introduced as an artists' pigment in 1852 (Saint-Evre) and began selling commercially in the U.S. in 1861. Aureolin is a permanent pigment, but may discolor to brown when mixed with indigo in the presence of hydrogen sulfide. Because of its poor hiding power, cobalt yellow is most often used in watercolor and tempera paints, for oil-based glazes and as a colorant in glass.
Synonyms and Related Terms
cobalt yellow; potassium cobaltinitrite; Pigment Yellow 40; CI 77357; Kobaltgelb (Deut.); aureolina (Esp.); jaune de cobalt (Fr.); giallo di cobalto (It.); aureolina (It.); amarillo de cobalto (Esp.)
Other Properties
Slightly soluble in water, ethanol, ether and carbon disulfide. Soluble in acids producing a pink solution. Decomposes in alkalis evolving nitrogen oxide fumes.
