WebHardness is a measure of how resistant a mineral is to scratching. This physical property is controlled by the chemical composition and structure of the mineral. Hardness is commonly measured on the Mohs scale. This is defined by ten minerals, where each mineral can scratch those with a lower scale number. The Mohs scale of mineral hardness is a qualitative ordinal scale, from 1 to 10, characterizing scratch resistance of minerals through the ability of harder material to scratch softer material. The scale was introduced in 1812 by the German geologist and mineralogist Friedrich Mohs, in his book "Versuch einer Elementar-Methode zur naturhistor…
