Mohs Hardness Scale: Testing the Resistance to

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.Mohs scale of mineral hardness - Wikipedia,The Mohs scale of mineral hardness (/ m oʊ z /) 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.Granite Hardness on the Mohs Scale for Stone,The Mohs Hardness Scale developed by Friedrich helps you decide the strength and hardness of any material or mineral. The more you move up the scale (1-10), the minerals become harder and harder. On the other hand, the below you go, the mineral becomes softer and softer, ending with the softest mineral. To sum up, this scale ranks a mineral,
