The Mohs hardness scale is a qualitative test that measures the hardness of a mineral by its ability to visibly scratch softer minerals. The scale isn’t perfect, but it’s a great tool for quick identification of rocks in the field.The hardness test developed by Friedrich Mohs was the first known test to assess resistance of a material to scratching. It is a very simple but inexact comparative test. Perhaps its simplicity has enabled it to become the most .
Geologists and gemologists use the Mohs hardness scale to measure the "scratchability" of minerals and gemstones, ranking them based on their ability to scratch or become scratched by other substances. To perform .
