How to know the Specific Gravity, Density, harness and more? Hardness of Diamonds and minerals is defined by measuring on the scale of Mosh in comparison from 1 for Talc to 10 for diamond. The Mohs hardness scale lists 10 common minerals, assigning to each a hardness from 1 to 10. Identifying Rocks and Minerals/Hardness - Wikibooks, open ... The Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. It was created in 1812 by the German mineralogist Friedrich Mohs and is one of several definitions of hardness in materials science. Exploring the Relationship of Scratch Resistance, Hardness ... test kits (most notably talc) may be impure and give variable results. For example, talc is commonly intergrown with amphibole, which has a Mohs hardness 56 Journal of Geoscience Education, v. 55, n. 1, January, 2007, p. 56-61 Exploring the Relationship of Scratch Resistance, Hardness, and other Physical Properties of Minerals using Mohs Scale ... Minerals - Hardness Hardness is a measure of a mineral's resistant to abrasion. This property is easily determined and is used widely for field identification of minerals. More than a century ago. Friedrich Mohs (1773-1839), a German mineralogist, assigned arbitrary relative numbers to ten common minerals in order of their hardness.    Read More
