what is mohs hardness scale

The Mohs Hardness Scale is a scale that ranks the hardness of minerals and other common objects in order. Such a material would be examined in reference to being scratched by one of the ten scale minerals or other minerals of a corresponding degree of hardness. The scale detects the hardness of the stones through a ranking that varies from 1 being the softest to 10 being the hardest material. 7. In short, the Mohs hardness scale measures the hardness of a crystal. The Mohs scale runs from 1 (softest) to 10 ( hardest ). So because diamond can scratch quartz, diamond is considered harder than quartz. These scales are not similar! A mineral's hardness is a measure of its relative resistance to scratching, measured by scratching the mineral against another substance of known hardness on the Mohs Hardness Scale. There are ten minerals used as a guide to the Mohs scale. It's typical to not see Talc - the usual "1" referenced by the scale - in these kits because it's regarded as the softest mineral around and won't actually scratch anything. Since hardness depends upon the crystallographic direction (ultimately on the strength of the bonds between atoms in a crystal), there can be variations in hardness depending upon .
