It is the main source of corundum that is used for abrasives. Asbestos. The dark mica mineral biotite (K(Mg,Fe) 3(Al,Fe)Si 3O 10 (OH,F) 2) should produce a white/colorless streak, but if you scratch a portion of the mineral that contains limonite, the streak will It removes the excessive stratum corneum instantly, smooths it and makes it more elastic. Phosphates. Corundum. It has a hardness of 8 on the Mohs hardness scale, making it the hardest silicate mineral.
