The Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material.
Mohs Scale of Mineral Hardness. In 1812 the Mohs scale of mineral hardness was devised by the German mineralogist Frederich Mohs (1773-1839), who selected the …

The 10-mineral Mohs scale of relative hardness is based on what scratches what.
Since few of us carry these index minerals around in our pockets, we can use more common articles to get a rough estimate of hardness.
Halite, the natural form of salt, is a very common and well-known mineral. It is found in solid masses, and as a dissolved solution in the oceans and in salt lakes.
