Granite is a very hard stone and resistant to damage. Though the composition of various granite colors and varieties will vary from slab to slab, granite is generally is made up of a quartz, feldspar and an assorted variety of minerals, evoking a gritty look. However, granite is still vulnerable to staining. Granite has a Mohs hardness rating

What is the Mohs Hardness Scale? The Mohs Hardness Scale was developed in 1812 by a German geologist and mineralogist, Friedrich Mohs to determine the relative hardness of a mineral as a comparison to another mineral. For example, the scale begins with the softest material, talc. All materials above talc have the ability to scratch talc.

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. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or defined hardness.. To give numerical values to this physical property, minerals are ranked

Hardness and Strength of Granite. The physical properties of Granite depend on its formation. Physical properties of rocks play an important role in determining its applications in various fields. Rocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 1-3 are soft rocks from 3-6
Mohs Scale of Relative Mineral Hardness. A German mineralogist by the name of Friedrich Mohs invented a scale of relative mineral hardness that has become known as the Mohs scale.

Mar 13, 2020· A Quick History of Mohs Hardness. We have Friedrich Mohs, a German mineralogist, to thank for the Mohs scale of mineral hardness. This essential scale is used to measure the scratch resistance of a material like quartz or granite. Possible measurements range from 1 to 10, with 1 indicating the softest material and 10 the hardest.
The first scale was devised by German geologist Friedrich Mohs. Mohs worked on cataloguing and developing a scale to evaluate the hardness of various minerals. In this way, he was able to determine that diamond is the hardest material. Cured concrete is a relatively hard material, as its hardness varies between 3 and 7 Mohs. Although this
Aug 30, 2012· The hardness of rocks, as measured by their resistance to abrasion, can be assessed on the Mohs scale. By this grade, which runs from one to 10, a mineral can scratch another of equal or lesser hardness. Rocks can be evaluated on the Mohs scale by considering their constituent minerals. Granite typically has a Mohs ranking between 5.5 and 7.
