Mohs scale of mineral hardness Wikipedia

The Mohs scale of mineral hardness 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. The method of comparing hardness by observing which minerals can scratch others is of great antiquity, having been mentioned by Theophrastusin his treatise

Mohs scale of mineral hardness Simple English Wikipedia

Mohs' scale of mineral hardness is named after Friedrich Mohs, a mineralogist.Mohs scale is ordered by hardness, determined by which minerals can scratch other minerals.. Rocks are made up of one or more minerals. According to the scale, Talc is the softest: it can be scratched by all other materials. Gypsum is harder: it can scratch talc but not calcite, which is even harder.
