Mohs Hardness Scale: Testing the Resistance to Being

2017-9-11  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.

Hardness: Mineral Properties - The Mineral and Gemstone ...

HARDNESS. Hardness plays a major role in identifying a mineral. It can make the identification process much simpler by considerably narrowing a search. Hardness is defined by how well a substance will resist scratching by another substance. For example, if mineral A scratches mineral B, and mineral B does not scratch mineral A, then mineral A ...

mineral - mineral - Hardness: Hardness (H) is the resistance of a mineral to scratching. It is a property by which minerals may be described relative to a standard scale of 10 minerals known as the Mohs scale of hardness. The degree of hardness is determined by observing the comparative ease or difficulty with which one mineral is scratched by another or by a steel tool.
