Mohs Scale of Hardness | Pohaku Fabrication KauaiTraduire cette page

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 known substance is diamonds, so naturally diamonds are rated a 10 out of 10 ...
