Barite is typically white/grey in appearance but can vary from yellow, brown, red, and even black due to impurities. Barite's Mohs hardness is 3.0 to 3.5, making it a relatively soft mineral. It is chemically inert and insoluble, which along with its high density, lends itself to a variety of applications.
