Bauxite Facts - Softschools

Bauxite is a mineral with a dull, earthy luster which is usually white or gray, though sometimes can be found stained by yellow, orange, red, pink, or brown by iron or included iron minerals. It has no cleavage, a low specific gravity, and the Mohs Hardness Scale score is between 1 and 3. Its streak is usually white, but its iron stain can discolor.

Mohs Hardness Scale | Geology Page

The hardness test developed by Friedrich Mohs was the first known test to assess resistance of a material to scratching. It is a very simple but inexact comparative test. Perhaps its simplicity has enabled it to become the most widely used hardness test. Since the Mohs Scale was developed in 1812, many different hardness tests have been invented.

Barite Mineral | Uses and Properties

Barite is generally easy to identify. It is one of just a few nonmetallic minerals with a specific gravity of four or higher. Combine that with its low Mohs hardness (2.5 to 3.5) and its three directions of right-angle cleavage, and the mineral can usually be reliably .
