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.
