This means that marble is less scratch resistant than granite.
Marble hardness on the mohs scale.
The hardness of any mineral is rated on a 1 to 10 scale called the mohs scale.
Granite is a blend of different minerals fused.
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.
Hardness is determined by the ability of one mineral to scratch another.
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.
To give numerical values to this physical property minerals are ranked along.
When black granite is measured on the mohs scale it falls somewhere between 6 and 7.
The mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or defined hardness.
The mohs scale of mineral hardness 1.
The translucence of marble makes it especially attractive for many types of sculptures.
As a result marble is less porous and slightly stronger than limestone but still less durable than granite.
On the other hand the softest is talc which ranks at a 1.
How is hardness rated.
Granite on the mohs scale.
This scale was invented by german mineralogist friedrich mohs in 1812 and ranks minerals based on their ability to scratch or sustain scratches.
Being composed of calcite marble has a hardness of three on the mohs hardness scale.
The hardest mineral on the mohs scale is diamond which ranks at a 10.
For example a diamond can scratch granite while granite can scratch marble.
Depending on the limestone and the mineral combination within the marble most marble rates from three to five on the mohs hardness scale.
Marble has a mohs hardness scale rating between 3 4.
As a result marble is easy to carve and that makes it useful for producing sculptures and ornamental objects.
What are the hardest and softest minerals on the mohs scale.

If you check granite hardness on the mohs scale you will find it harder than marble and softer than quartzite.
Find out more about the hardness of granite by reading on.
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.
In simple words soapstone is the softest material and diamond is the hardest material.
On average it is 6 5.
