The hardness of a mineral is often defined by using Moh's Scale of Relative Hardness. This scale was developed in 1822 by Friedrich Moh to measure the hardness of minerals. The idea behind Moh's Scale was that minerals or substances with a lower hardness could not scratch minerals or substances with a greater hardness.
The classic scale for hardness was published in 1822 by Frederick Mohs an Austrian mineralogist who got the basic concept from tests performed routinely by miners. The scale selects 10 minerals as standards, arranging in order of increasing hardness.
German mineralogist Frederich Mohs' 1812 Hardness Scale associated a hardness score with 10 common minerals, with diamonds scored as the hardest, at 10, and talc the least hard, at 1. Minerals with higher numbers can scratch any mineral with a lower number, and lower numbers can never scratch a higher numbered mineral.
Devised by Austrian mineralogist Frederick Mohs in 1822, Mohs' Hardness is applied to nonmetallic elements and minerals. In this scale, hardness is defined by how well a substance resists scratching by another substance. A scale of 1 to 10 with halfstep increments is employed.
