Marble Hardness On The Mohs Scale

The mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or defined hardness.

Marble hardness on the mohs scale.

Marble has a mohs hardness scale rating between 3 4. 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. On average it is 6 5. Granite on the mohs scale.

As a result marble is easy to carve and that makes it useful for producing sculptures and ornamental objects. Marble is limestone that has been compacted and heated over millions of years. On the other hand the softest is talc which ranks at a 1. Mohs hardness rough measure of the resistance of a smooth surface to scratching or abrasion expressed in terms of a scale devised 1812 by the german mineralogist friedrich mohs.

To give numerical values to this physical property minerals are ranked along. How is hardness rated. The mohs scale of mineral hardness 1. If you check granite hardness on the mohs scale you will find it harder than marble and softer than quartzite.

The hardness of any mineral is rated on a 1 to 10 scale called the mohs scale. For example a diamond can scratch granite while granite can scratch marble. The translucence of marble makes it especially attractive for many types of sculptures. Granite is a blend of different minerals fused.

Find out more about the hardness of granite by reading on. As a result marble is less porous and slightly stronger than limestone but still less durable than granite. This means that marble is less scratch resistant than granite. 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. When black granite is measured on the mohs scale it falls somewhere between 6 and 7. 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.

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. Depending on the limestone and the mineral combination within the marble most marble rates from three to five on the mohs hardness scale. The result is this ordinal scale of minerals by hardness with 1 being the softest and 10 being the hardest. What are the hardest and softest minerals on the mohs scale.
