Mohs scale of mineral hardness - Wikipedia

The Mohs scale of mineral hardness 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. The method of comparing hardness by observing which minerals can scratch others is of great antiquity, having been mentioned by Theophrastusin his treatise …

Gypsum is harder: it can scratch talc but not calcite, which is even harder.

Mineral Scales and Deposits | ScienceDirect

Control of mineral scales may include costly water purification to remove scale-forming components or a simple addition of antiscaling chemicals. Although the use of antiscalants has very long history, it still relies more on experience and empirical solutions than on fundamental understanding of mechanisms by which these chemicals can reduce or prevent scale formation.

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.

Mohs Scale of Hardness - Mineralogical Society of America

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.
