Group 6 element

At first, crocoite from Russia was the main source, but in 1827, a larger chromite deposit was discovered near Baltimore, United States.

Chromium was first reported on July 26, 1761, when Johann Gottlob Lehmann found an orange-red mineral in the Beryozovskoye mines in the Ural Mountains of Russia, which he named "Siberian red lead," which was found out in less than 10 years to be a bright yellow pigment.
