  • Mohs Scale of Hardness Pohaku Fabrication Kauai

    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.

  • Limestone: Rock Uses, Formation, Composition, Pictures

It most commonly forms in clear, warm, shallow marine waters. It is usually an organic sedimentary rock that forms from the accumulation of shell, coral, algal, and fecal debris. It can also be a chemical sedimentary rock formed by the precipitation of calcium carbonate from lake or ocean water. Most limestones form in shallow, calm, warm marine waters. That type of environment is where organis
  • Mineral Hardness Scale Specialty Kitchens

    The hardness of material is measured by determining which material can scratch or be scratched by others, if they can scratch one another then they are the same hardness. For example if a given material is scratched by Corundum but not by Diamond, its hardness on the Mohs scale is 9.5. The Mohs scale is truly a comparative scale.
