hardnesses
Degrees of firmness
Hardnesses is the plural of hardness, referring to multiple instances or types of resistance to pressure, scratching, or penetration.
Materials have different hardnesses measured on various scales: The Mohs scale ranks mineral hardnesses from talite to diamond.
The term appears in technical contexts comparing the hardnesses of metals, gemstones, or other substances.
