Though misidentified as a moderate compou nd with selenium and iron components, the material was in incident lead chromate with a formula of PbCrO4, now cognise as the mineral crocoite. In 1770, Peter Simon Pallas vi commitd the same site as Lehmann and found a red lead mineral that had very useful properties as a pigment in paints. The use of Siberian red lead as a paint pigment developed rapidly.

A bright yellow(a) substancemade from crocoite also became fashion commensurate. In 1797, Louis Nicolas Vauquelin received samples of crocoite ore. He was able to seduce chromium oxide with a chemical formula of CrO3, by miscellany crocoite with hydrochlor ic acid. In 1798, Vauquelin discovered that ! he could isolate metallic-looking chromium by heating the oxide in a lignite oven. He was also able to detect traces of chromium in precious gemstones, such as ruby, or emerald. Later that family he successfully isolated elemental chromium. During the 1800s chromium was in the beginning used as a component of paints and in slaughter salts but now metal alloys account for 85% of the use of chromium.
