Rating Minerals on Mohs Scale of Hardness

2019-5-13  Mohs hardness scale was devised in 1812 by Friedrich Mohs and has been the same ever since, making it the oldest standard scale in geology. It is also perhaps the most useful single test for identifying and describing minerals. You use the Mohs hardness scale by testing an unknown mineral against one of the standard minerals.

An Updated Extended Mohs Mineral Hardness Scale

2021-2-17  Friedrich Mohs (1773-1839), an Austrian/German mineralogist, developed a scale of hardness for minerals in 1812 (although some sources reference 1822). This hardness scale classifies minerals on a scale from one (the softest) to ten (the hardest) and has been used by mineralogists since its inception. The minerals Friedrich Mohs selected for ...
