Mohs scale of mineral hardness Wikipedia

The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative.

MOHS' SCALE OF HARDNESS

This scale is a chart of relative hardness of the various minerals (1 softest to 10 hardest). Since hardness depends upon the crystallographic direction (ultimately on the strength of the bonds between atoms in a crystal), there can be variations in hardness depending upon the direction in which one measures this property.

Mohs scale of mineral hardness Simple English Wikipedia

The hardness of a mineral is mainly controlled by the strength of the bonding between the atoms and partly by the size of the atoms. It is a measure of the resistance of the mineral to scratching, the Mohs scale is for natural minerals. For manufactured products other measures of hardness are better.

Gemstone Hardness Scale MOHS [With Table] Gem Rock Auctions

The MOHS scale was created by trying to scratch one mineral with another, and then recording which mineral left a scratch. Fro example, Corundum (Sapphire and Ruby) was used to scratch Apatite.Corundum left a scratch on the surface of Apatite, and so this mineral should sit higher on the scale.

Mineral Gallery: Hardness

A mineral can only be scratched by a harder substance. A hard mineral can scratch a softer mineral, but a soft mineral can not scratch a harder mineral (no matter how hard you try). Therefore, a relative scale can be established to account for the differences in hardness simply by seeing which mineral scratches another.
