What is the Mohs Hardness Scale? The Mohs Hardness Scale was developed in 1812 by a German geologist and mineralogist, Friedrich Mohs to determine the relative hardness of a mineral as a comparison to another mineral. For example, the scale begins with the softest material, talc. All materials above talc have the ability to scratch talc.

Mar 15, 2020· If you can, test your specimen against other points to get a good idea of its hardness. For example, if you scatch your specimen with glass, you know its hardness is less than 6. If you can't scratch it with a penny, you know its hardness is between 3 and 6. The calcite in this photo has a Mohs hardness of 3.

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.
