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.
Mineral Hardness. The hardness of a mineral is a way of describing how easy or difficult it is to scratch the mineral. It is used, in combination with the other physical properties, to help identify a mineral specimen. In mineral books, hardness is shown using the letter âH.â An example of this is âTalc, H1â. Mineralogists realized that a way to measure the hardness of minerals was needed. In 1824, a mineralogist from Austria named Friederich Mohs chose 10 common minerals and arranged them in order from softest to hardest. This is called the Mohs Scale of Hardness and today is used by mineralogists all over the world. The Mohs Scale of Hardness: 1. Talc . 2.
