Description
A toxic yellow artist's pigment containing Lead chromate sometimes mixed with Lead sulfate. Lead chromate can range in shade from lemon yellow to orange depending on its particle size, hydration state, and percent lead chromate. Chrome yellow, which came on the market in early 1800s, is permanent to visible light, but can darken with exposure to UV radiation or Hydrogen sulfide. Chrome yellow is used in industrial paints, some artist's paints and ceramic glazes.
Other yellow chromate pigments are sometimes also called chrome yellow. Strontium chromate, zinc chromate, and Barium chromate are pale yellow pigments that are often mixed and called lemon yellow. Strontium chromate has more hiding power than the barium chromate. Zinc yellow is synthetically prepared zinc chromate. The pure material is stable and is used in oil and watercolor paints.
