The Mohs scale of mineral hardness is based on the ability of one natural sample of mineral to scratch another mineral visibly. The samples of matter used by Mohs are all different minerals. Minerals are pure substances found in nature. Rocks are made up of one or more minerals.
How do you read the Mohs scale of hardness? the bigger the number for that particular mineral, the harder it is. it ranges from 1-10, diamond being 10, the hardest. Edit
