• Mohs scale of mineral hardness - Simple English Wikipedia ...

    simple.wikipedia.org/wiki/Mohs_scale_of_mineral_hardness 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.
  • Mohs scale of mineral hardness - Wikipedia

    en.wikipedia.org/wiki/Mohs_scale_of_mineral_hardness The 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.
  • Mohs Hardness Scale: Testing the Resistance to Being Scratched

    geology.com/minerals/mohs-hardness-scale.shtml What is Mohs Hardness Scale? One of the most important tests for identifying mineral specimens is the Mohs Hardness Test. This test compares the resistance of a mineral to being scratched by ten reference minerals known as the Mohs Hardness Scale (see table at left). The test is useful because most specimens of a given mineral are very close to the same hardness.

    www.amfed.org/t_mohs.htm 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 ten minerals because they were common or readily available. The scale is not a linear scale, but somewhat arbitrary.
