[2] The raw pigment precipitates as a fine solid upon mixing lead(II) salts and a source of chromate.
[2] Related lead sulfochromate pigments are produced by the replacement of some chromate by sulfate, resulting in a mixed lead-chromate-sulfate compositions Pb(CrO4)1-x(SO4)x.
[6] Owing to its high lead content, the pigment is prone to discoloration over time, particularly in the presence of sulfur compounds.
Its low cost had doubtlessly contributed to its continued use as an artists' color even though some subsequently discovered yellow pigments are more permanent.
The discovery of lead chromate, the primary component of chrome yellow, is credited to the French chemist Louis Nicolas Vauquelin.
Vauquelin was studying the mineral crocoite, a natural form of lead chromate, when he identified the presence of a new element, chromium.
[12] Chrome yellow quickly gained popularity among artists and designers for its bright, sunny hue, which was particularly well-suited for use in fashion and textiles.
The continued wide use of this pigment is attributed to its very low solubility, which suppresses leaching of chromate and lead into biological fluids.
