Hardness, how easily it can be scratched
Mohs introduced the scale of mineral hardness - Mohs scale - named for him. Ten minerals whose hardness is known are ordered on a scale ranging from 1 (http://www.answers.com/topic/talc?initiator=WANSalc) to 10 (diamond),
The Mohs scale is used to determine the relative hardness of minerals.
Hardness test based on the Mohs Scale of relative mineral hardness, specific gravity, streak test for mineral color, classification of mineral crystal system, chemical analysis.

On the Mohs scale of mineral hardness, corundum is listed as a 9, below diamond which has a rating of 10.
The Mohs scale is used to measure the hardness of minerals.
B. Hardness
Scientists use the Mohs scale of mineral hardness to determine the relative hardness of minerals. This scale ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals. By performing a scratch test, scientists can identify a mineral's hardness by comparing it to known minerals on the Mohs scale.
The Mohs scale is a measure of hardness, not crystal shape. Crystal shape is determined by the internal arrangement of atoms in a mineral and is usually identified using X-ray crystallography or microscopy techniques.

to identify a mineral
Minerals have a fairly specific range of hardness, based on the Mohs hardness scale. The Mohs scale is based on the ability of a mineral to be scratched, or scratch, another mineral. Using the Mohs scale to determine mineral hardness is one test that can be used to help identify one mineral from others.
the hardness of minerals.
This scale is correctly called the Mohs scale. Scientists use this scale to measure a rock's hardness or softness. They can discover how hard a mineral or rocks is and drill in to it and find out more about it.
It's called the Ore
The scale used to identify minerals is called the Mohs scale of mineral hardness. It ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals.
Scientists use the hardness test, and more specifically Mohs Hardness Scale, named after a Freidrich Mohs, a German mineralogist. Mohs Hardness Scale test can scale from 1 to 10, where 1 is softest and 10 is hardest.
