The Concept of Hardness As Applied to Mineral Aggregates

The Mohs scale of scratch hardness (the concept on which the scratch hardness test is based) was developed in 1812 as a simple guide to aid in the identification of minerals. The scale chosen was a qualitative measure of abrasive hardness intended solely to relatively evaluate the normal rock forming minerals. This simple scale of 1 to 10
