Marble On The Hardness Scale

On average it is 6 5.

Marble on the hardness scale.

In simple words soapstone is the softest material and diamond is the hardest material. 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. When black granite is measured on the mohs scale it falls somewhere between 6 and 7. Marble is limestone that has been compacted and heated over millions of years.

As a result marble is easy to carve and that makes it useful for producing sculptures and ornamental objects. 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. Marble has a mohs hardness scale rating between 3 4. An example of the hardness of a granite countertop can be seen in the fact that a knife blade will not scratch the surface.

It can also be used for metal. For example a diamond can scratch granite while granite can scratch marble. Granite on the mohs scale. If you check granite hardness on the mohs scale you will find it harder than marble and softer than quartzite.

Being composed of calcite marble has a hardness of three on the mohs hardness scale. As a result marble is less porous and slightly stronger than limestone but still less durable than granite. 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. This means that marble is less scratch resistant than granite.
