The Mohs hardness scale, developed by Friedrich Mohs in 1812, is a qualitative ordinal scale that ranks minerals from 1 to 10 based on their ability to resist scratching by other minerals, with talc rated as the softest (1) and diamond as the hardest (10). Each mineral can scratch those below it and be scratched by those above it.
