For example a diamond can scratch granite while granite can scratch marble.

Marble hard or soft moh s scale.

The hardest mineral on the mohs scale is diamond which ranks at a 10. This means that marble is less scratch resistant than granite. The mohs scale of mineral hardness m oʊ z is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Granite is a blend of different minerals fused.

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. As a result marble is less porous and slightly stronger than limestone but still less durable than granite. In simple words soapstone is the softest material and diamond is the hardest material. This scale was invented by german mineralogist friedrich mohs in 1812 and ranks minerals based on their ability to scratch or sustain scratches.

The result is this ordinal scale of minerals by hardness with 1 being the softest and 10 being the hardest. A ranking of 1 means the mineral is very soft while a ranking of 10 means it is very hard. To give you an idea of how durable the stones in our staircases and fireplaces are we have added them to our revised version of the hardness scale. Quartz is 7 on mohs hardness scale.

Not only does this make for a tough stone but it also makes it easy to tell quartzite from the imposters. Hardness is determined by the ability of one mineral to scratch another. As a result marble is easy to carve and that makes it useful for producing sculptures and ornamental objects. Marble has a mohs hardness scale rating between 3 4.

Hardness is based on the mohs scale which ranks natural minerals on a scale of 1 to 10 1 being the softest and 10 being the hardest. When black granite is measured on the mohs scale it falls somewhere between 6 and 7. Granite comes in at a 6 to 7 on the mohs scale meaning it is relatively hard. On average it is 6 5.
