The Mohs Hardness Scale is a qualitative scale used for determining a mineral's hardness by scratching it against another material with a known hardness. It helps in identifying minerals and their ranks, with the scale ranging from 1 (talc) to 10 (diamond), depending on the material's resistance to being scratched.

In 1812 (or possibly 1822), the Mohs scale of mineral hardness was devised by the German mineralogist Friederich Mohs (1773-1839), who selected the ten minerals because they were common or readily available. The scale is not a linear scale, but somewhat arbitrary. ... Quartz is fairly common and easy to find. Because of its piezoelectric ...
