The hardness of minerals is commonly tested using the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch each other. The scale was devised by Friedrich Mohs in 1812 and is still widely used in geology and mineralogy for identifying and comparing the hardness of different minerals.

This scale was proposed by the Austrian geologist Friderich Mohs.

Friedrich Mohs was a German mineralogist who developed the Mohs scale of mineral hardness in 1812. This scale ranks minerals based on their scratch resistance, with diamond being the hardest mineral ranking at 10.
Friedrich Mohs is famous for creating the Mohs scale of mineral hardness. He formulated a scale of one to ten and assigned each mineral a value. This eventually became the basis for the Mohs scale.
The Mohs standard hardness scale that was developed by Friedrich Mohs (1773 - 1839).
