Answer 1

Mohs hardness test uses 10 reference materials of varying hardness as the scale for the test. The softest material used is talc (value=1) and the hardest material is diamond (value=10). Given that the references used for the Mohs scale do not have a graded increase, the Mohs scale lacks accuracy and is only a rough measure of hardness.
