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.
Marble on the hardness scale.
When black granite is measured on the mohs scale it falls somewhere between 6 and 7.
The translucence of marble makes it especially attractive for many types of sculptures.
Marble has a mohs hardness scale rating between 3 4.
Depending on the limestone and the mineral combination within the marble most marble rates from three to five on the mohs hardness scale.
An example of the hardness of a granite countertop can be seen in the fact that a knife blade will not scratch the surface.
Marble is limestone that has been compacted and heated over millions of years.
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.
Hardness is determined by the ability of one mineral to scratch another.
This means that marble is less scratch resistant than granite.
Granite on the mohs scale.
Being composed of calcite marble has a hardness of three on the mohs hardness scale.
On average it is 6 5.
As a result marble is less porous and slightly stronger than limestone but still less durable than granite.
Because granite is between a 6 and 7 on the mohs scale it would be able to scratch other types of stone that have lower ratings such as marble.
It can also be used for metal.
