Mohs Scale of Hardness Pohaku Fabrication Kauai

Mohs Scale of Hardness. The Mohs Scale of Hardness was created in 1812 by German geologist/mineralogist Friedrich Mohs. This method of hardness judgement is based on the ability of one sample of matter to scratch another. So a mineral ranked 8 out of 10 is harder and will scratch a mineral ranked 3. When the scale was designed, the hardest ...
