    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 ...

    Dec 10, 2002 Stocks also conducted experiments on cutting limestone with bow-powered coring drills. The rate of cutting limestone with a copper barrel was 15 times greater than that observed in granite (Stocks 1999). The rate of copper loss would be expected to be very low, due to the similarity in hardness between the mineral calcite and copper.
