10 Facts About the Element Chromium - ThoughtCo

Chromium is used to prepare pigments (including yellow, red, and green), to color glass green, to color rubies red and emeralds green, in some tanning processes, as a decorative and protective metal coating, and as a catalyst. Chromium in air is passivated by oxygen, forming a protective layer that is essentially a spinel that is a few atoms thick.
