Hardness, how easily it can be scratched
Scientists use the Mohs' Scale to measure the hardness of any material - it ranges from 1 (talcum powder) to 10 (diamond).
All minerals have a figure somewhere along the scale.
Hardness
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 identify the mineral property of hardness only.
The Mohs scale is used to measure the hardness of minerals.
B. Hardness
The Mohs scale of mineral hardness is generally used to determine the hardness of a mineral. The Mohs scale rates the ability of mineral to scratch or be scratched by another 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.

Friedrich Mohs is famous for creating the Mohs scale of mineral hardness. He formulated a scale of one to ten and assigned each mineral a value. This eventually became the basis for the Mohs scale.
