It’s vital to understand that the Mohs scale is not a linear scale.Instead, it ranks minerals on a relative scale based on their scratch hardness, so although corundum (ruby or sapphire) is a 9, a diamond at 10 is almost 5 times harder (according to Vickers Absolute Hardness Scale) and 3 times harder (according to Knoops Absolute . The choice is not only between the regular hardness test and superficial hardness test, with three different major loads for each, but also between the diamond indenter and the 1/16, 1/8, 1/4 and 1/2 in. diameter steel ball indenters.More simply put, when using a fixed force (load)* and a given indenter, the smaller the indentation, the harder the material. Indentation hardness value is obtained by measuring the depth or the area of the indentation using one of over 12 different test methods. Hardness testing is used for two general characterizations 1.Material Characteristics

Steps for Performing the Mohs Hardness Test . Find a clean surface on the specimen to be tested. Try to scratch this surface with the point of an object of known hardness, by pressing it firmly into and across your test specimen.For example, you could try to scratch the surface with the point on a crystal of quartz (hardness of 9), the tip of a steel file (hardness .

A Rockwell hardness tester. The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1] There are different scales, denoted by a single letter, that use different loads or indenters.
