    What is Mohs Hardness Scale? One of the most important tests for identifying mineral specimens is the Mohs Hardness Test. This test compares the resistance of a mineral to being scratched by ten reference minerals known as the Mohs Hardness Scale (see table at left). The test is useful because most specimens of a given mineral are very close to the same hardness.

  • Barite Mineral | Uses and Properties

    Physical Properties of Barite 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 identified with just three observations.

    Jan 02, 2014· Barite is a mineral composed of barium sulfate, BaSO4. It is usually colorless or milky white, but can be almost any color, depending on the impurities trapped in the crystals during their formation. Barite is relatively soft, measuring 3-3.5 on Mohs' scale of hardness. It is unusually heavy for a non-metallic mineral.

  • Gemstone Hardness: The Definitive Guide at AJS Gems

    In gemology, gem hardness is measured on a scale known as the Mohs scale, which assigns minerals a value between 1 (softest) and 10 (hardest). This scale was devised by a German mineralogist, Frederick Mohs, in 1822. It defines hardness in terms of scratch resistance, where a harder mineral will scratch a softer one, but not vice versa.

    Hardness Hardness determines whether an abrasive particle can etch or provide an anchor pattern on a particular substrate. One way to determine the hardness of an abrasive is to use the Mohs' hardness scale. The scale ranges from 1 to 10, with 1 being the softest (talc) and 10 being the hardest (diamond).
