What is Mohs scale and how does it work?
The Mohs Hardness Scale is used as a convenient way to help identify minerals. A mineral’s hardness is a measure of its relative resistance to scratching, measured by scratching the mineral against another substance of known hardness on the Mohs Hardness Scale.
Is the Mohs scale logarithmic?
The Mohs’ scale is a comparative index rather than a linear scale. In fact, Mohs’ scale has a near logarithmic relationship to absolute hardness.
What is a diamond on the Mohs scale?

What is pyrite on the Mohs scale?
Pyrite has a hardness of 6 to 6.5, too hard to be scratched with a steel penknife. When testing for hardness, people sometimes mistake the powder of the softer mineral for a scratch on the harder one.
What is the Mohs hardness scale and how is it used?
The Mohs Hardness Scale is used as a convenient way to help identify minerals. A mineral’s hardness is a measure of its relative resistance to scratching, measured by scratching the mineral against another substance of known hardness on the Mohs Hardness Scale.
What is the hardest mineral on the Mohs scale?
Talc is the softest known natural mineral. It is given the designation of 1 on the Mohs hardness scale, which gauges the relative hardness of a substance, usually an unknown mineral. The hardest known natural mineral is diamond, which is designated 10 on the Mohs hardness scale.
What is the property measured by the Mohs scale?
The Mohs scale of mineral hardness (/ moʊz /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material.
How hard is concrete on Mohs scale?
The Mohs’ Hardness Pick Set, made of metals and alloys of hardness values equal to 2 through 9 on Mohs’ hardness scale, allows you to determine the hardness of the concrete you are working. The picks are made of metal and are easily ground to sharp points which will not break off and which can be easily sharpened.
