    Hardness. Definition. A measure of the ease with which a smooth surface of a mineral can be scratched, or of its resistance to abrasion. In 1822 the Austrian mineralogist Friedrich Mohs devised a scale based on one mineral's ability to scratch another. He placed 10 minerals in order from softest to hardest, giving a relative
