Streak & Magnetism Test Mohs Hardness Test Determining the hardness of an unknown rock or mineral is often very useful in the identification process.
  • Hardness is a measure of a mineral's resistance to abrasion and is measured against a standard scale - Mohs Scale of Hardness. Mohs Scale was named after Frederick Mohs (1773-1839), a German minerologist. It consists of 10 fairly common minerals (except for the diamond) of known hardness which are numerically ordered from the softest (1) to the hardest (10).
  • They are: 1. Talc (H=1) 2. Gypsum (H=2) 3. Calcite (H=3) 4. Fluorite (H=4) 5. Apatite (H=5) 6. Orthoclase (H=6) 7. Quartz (H=7) 8. Topaz (H=8) 9. Corundum (H=9) 10. Diamond (H=10) As common sense dictates, Mohs Scale is based on the fact that a harder material will scratch a softer one. By using a simple scratch test, you can determine the relative hardness of an unknown mineral. The Mohs scale is strictly a relative scale, but that's all that anyone needs. In terms of absolute hardness, diamond
  • The scale uses half-numbers, but nothing more precise, for in-between hardnesses. For instance, dolomite, which scratches calcite but not fluorite, has a Mohs hardness of 3½ or 3.5. "Tools" for Testing Hardness
  • Believe it or not, most people do not normally carry around samples of the 10 minerals on the Mohs Scale! However, there are several simple "tools" people often have with them that can be useful in determining the relative hardness of an unknown mineral specimen.
