    Mohs Hardness Test Oakton Community College

    The Mohs Hardness Test During the early 1800s, a German mineralogist named Friedrich Mohs devised a scale that tested mineral hardness, which means the resistance of a mineral to being scratched. This scale, which ran from 1 to 10, was named after Mohs, and is known as the Mohs Hardness Test.

    Streak Test for Minerals using a porcelain streak plate

    The "streak test" is a method used to determine the color of a mineral in powdered form. The color of a mineral's powder is often a very important property for identifying the mineral. The streak test is done by scraping a specimen of the mineral across a piece of unglazed porcelain known as a "streak plate." This can produce a small amount of powdered mineral on the surface of the plate.
