Moh’s scale
Mohsova skalaMohs’ scale of mineral hardness characterises the scratch resistance of various minerals through the ability of a harder material to scratch a softer. It was created by the German mineralogist Friedrich Mohs (1773-1839). Mohs based the scale on the ten readily available minerals.
| Hardness | Mineral |
|---|---|
| 1 | talc (Mg3Si4O10(OH)2) |
| 2 | gypsum (CaSO4·2H2O) |
| 3 | calcite (CaCO3) |
| 4 | fluorite (CaF2) |
| 5 | apatite (Ca5(PO4)3(OH-,Cl-,F-)) |
| 6 | orthoclase feldspar (KAlSi3O8) |
| 7 | quartz (SiO2) |
| 8 | topaz (Al2SiO4(OH-,F-)2) |
| 9 | corundum (Al2O2) |
| 10 | diamond (C) |
