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
