The Mohs’ hardness scale was developed in 1822 by Carl Friedrich Christian Mohs (a german geologist and mineralogist). This scale is a chart of relative hardness and resistance of the various minerals (1 – softest to 10 – hardest). Hardness is determined by scratching the mineral with a mineral or substance of known hardness.
