• Mohs Hardness Scale: Testing the Resistance to Being Scratched

    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.

    OverviewUsageMineralsSee alsoFurther reading

    The Mohs scale of mineral hardness is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative. The method of comparing hardness by observing which minerals can scratch others is of great antiquity, having been mentioned by Theophrastusin his treatise
