Copper coin (5 Bani) for Mohs Hardness testYour model is disabled. For more details go to Edit properties3D Model
Note: The purpose of this 3D model is to represent the Mohs’ scale of mineral hardness.
Copper coin hardness: about 3.5
Mohs’ scale of mineral hardness was created in 1812 by the German mineralogist Friedrich Mohs.
Mohs’ scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. For instance, if you scratched a diamond along a pane of glass, the glass would scratch and it wouldn’t harm the diamond in any way.
Mohs’ scale of mineral hardness is a purely ordinal scale with, for example, Corundum being twice as hard as Topaz, but Diamond almost four times as hard as Corundum. So, a diamond is the hardest substance known to man.
