A bright yellow(a) substancemade from crocoite also became fashion qualified. 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 h ydrochloric acid. In 1798, Vauquelin discove! red that he could isolate metallic-looking chromium by heating the oxide in a brown coal oven. He was also able to detect traces of chromium in precious gemstones, such as ruby, or emerald. Later that yr he successfully isolated elemental chromium.
