Template:THANKSALOT Invented by German geologist Friedrich Mohs, the Mohs Hardness Scale is used in geology to measure the hardness of a rock or mineral. The higher on the scale a material is, the harder it is. Any material that has a certain number on the Mohs scale can scratch any specimen with a smaller number, but can be scratched itself by a another specimen of the same type or with a higher number. The $10$ classical exemplars are listed here, with a few notable objects in between for the purpose of comparison.
