Radon mohs hardness
WebThe Mohs hardness thus represents a significant quality feature of porcelain and ceramics. The counting and presentation of Mohs hardness was carried out until 2001 under the regulation of DIN-Standard norm DIN EN-101. In this case, the detected hardness of damage was shown out. By this kind of counting the real hardness of the mineral ...

http://chemreference.com/#! The Mohs scale of mineral hardness is based on the ability of one natural sample of mineral to scratch another mineral visibly. The samples of matter used by Mohs are all different minerals. Minerals are chemically pure solids found in nature. Rocks are made up of one or more minerals. As the hardest known naturally occurring substance when the scale was designed, diamonds are at the top of the scale. The hardness of a material is measured against the scale by finding the h…
