  • A scale of 1 to 10 used for determining a mineral's hardness, introduced by German geologist Friedrich Mohs in 1812. To apply the scale, the measurer attempts to scratch the mineral with standard minerals assigned hardness numbers as follows: diamond 10, corundum 9, topaz 8, quartz 7, orthoclase 6, apatite 5, fluorite 4, calcite 3, gypsum 2, and talc 1. If, for example, the mineral is scratched by quartz but not by orthoclase, then its hardness is between 6 and 7.
