Detailed explanation-1: -Hardness is which kind of property? Explanation: Hardness is an anisotropic property; a mineral may show different values in different directions.
Detailed explanation-2: -Hardness is just one mechanical measurement and properties such as toughness and strength need to be considered, as hard materials tend to have low toughness and can easily fracture. Hardness can be assessed by a number of techniques including indentation, scratch and rebound hardness measurements.
Detailed explanation-3: -Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
Detailed explanation-4: -Hardness of human finger nail varies between 1.5 and 2.5.
