Mohs scale of mineral hardness - Designing Buildings

The Mohs hardness scale designates the hardness class of mineral based material. It is used to describe how substances behave when a hard material scratches a soft material. The scale ranges from 1 to 10, where 1 is talc (softest) and 10 is diamond (hardest). The scale is named for its originator, Friedrich Mohs.

Rating Minerals on Mohs Scale of Hardness -

2019-5-13  Mohs hardness scale was devised in 1812 by Friedrich Mohs and has been the same ever since, making it the oldest standard scale in geology.

Mineral Study Guide - Mohs Hardness

A simplified and crude test for hardness is to test whether or not a sharp corner or edge of a sample scratches (or indents) a glass plate. A numerical reference scale for hardness was devised by Mohs. A glass plate has a hardness of about 5 1/2 on the Mohs hardness scale. More information on hardness in mineral identification
