en.wikipedia.org/wiki/Mohs_scale_of_mineral_hardnessThe Mohs scale of mineral hardness (/ m oʊ z /) 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.
simple.wikipedia.org/wiki/Mohs_scale_of_mineral_hardnessMohs' scale of mineral hardness is named after Friedrich Mohs, a mineralogist. Mohs invented a scale of hardness based on how one mineral scratched another. 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.
geology.com/minerals/mohs-hardness-scale.shtmlMohs - Vickers hardness comparison: This chart compares the hardness of index minerals of the Mohs hardness scale (an integer scale) with their Vickers hardness (a continuous scale). Mohs hardness is a resistance to being scratched, while Vickers hardness is a resistance to indentation under pressure.
www.amfed.org/t_mohs.htmMohs 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 ten minerals because they were common or readily available. The scale is not a linear scale, but somewhat arbitrary.

The Moh's (Mohs) scale of hardness is the most common method used to rank gemstones and minerals according to hardness. Devised by German mineralogist Friedrich Moh in 1812, this scale grades minerals on a scale from 1 (very soft) to 10 (very hard). ...
