Answer 1
Mohs Hardness Scale is a comparative way of measuring the hardness of a rock or mineral - that is, its resistance to scratching. It is usually used with minerals because rocks tend to have a heterogeneous consistency and therefore varying degrees of hardness.
The Mohs scale goes from 1 to 10, with one being the softest mineral and ten being the hardest. There are minerals that are considered "indicators" and are known to have a specific, constant hardness value. These indicator minerals, with their hardness values, are:
Talc: 1 (softest)
Gypsum: 2
Calcite: 3
Fluorite: 4
Apatite: 5
Feldspar: 6
Quartz: 7
Topaz: 8
Corundum: 9
Diamond: 10 (hardest)
A set of common objects with known hardness values is often used to estimate the hardness of an unknown sample, by attempting to scratch it. The average human fingernail has a hardness of 2.5 and a copper penny has a hardness of 3.5. A stainless steel blade is about 6.5 and a section of average window glass is approximately 5.5.

Answer 2
The Mohs scale of mineral hardness is based on the ability of one natural sample of matter to scratch another mineral. The samples of matter used by Mohs are all different minerals. Minerals are pure substances found in nature.
1 = talcum, softest
10= diamond, hardest
