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 get price

Mohs Hardness Scale Geology Page

What is Mohs Hardness Scale? One of the most important tests for identifying mineral specimens is the Mohs Hardness Test. This test compares the resistance of a mineral to being scratched by ten reference minerals known as the Mohs Hardness Scale (see table at left). The test is useful because most specimens of a given mineral are very close to the same hardness.get price

Mohs' Hardness (Typical) of Abrasives

Hardness Hardness determines whether an abrasive particle can etch or provide an anchor pattern on a particular substrate. One way to determine the hardness of an abrasive is to use the Mohs' hardness scale. The scale ranges from 1 to 10, with 1 being the softest (talc) and 10 being the hardest (diamond).get price

Hard cannot be scratched by a knife but can scratch glass, Mohs' 6-9; Diamond is the hardest known mineral, Mohs' 10. Notes: It must be noted that Mohs' scale is arbitrary and non-linear, i.e. the steps between relative hardness values are not necessarily equal. Rather, it is a method of gauging the relative hardness of a mineral.get price

Kyanite Hardness GemSelect

Aug 15, 2008· Many minerals exhibit variable hardness depending on their axes, due to slight variations in the crystals. Kyanite exhibits a marked variation in hardness. When it is cut parallel to its long axis, the hardness of kyanite can range from 4 to 4.5 on the Mohs scale, but when cut perpendicularly, its hardness can range from 6 to 7 in the same crystal.get price
