Detailed explanation-1: -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.
Detailed explanation-2: -Mohs Scale of Hardness. The Mohs’ hardness scale was developed in 1822 by Frederich Mohs. This scale is a chart of relative hardness of the various minerals (1-softest to 10-hardest).
Detailed explanation-3: -The Mohs scale of mineral hardness is an ordinal scale that tests the hardness of minerals based on their ability to scratch softer materials. The Mohs scale runs from 1 (softest) to 10 (hardest).
Detailed explanation-4: -The Mohs Hardness Scale is used as a convenient way to help identify minerals. A mineral’s hardness is a measure of its relative resistance to scratching, measured by scratching the mineral against another substance of known hardness on the Mohs Hardness Scale.
Detailed explanation-5: -Below is the Mohs Scale in Minerals and other materials. #1 – Talc, the softest mineral, used to make talcum powder and rubber lubricant.
