Marble - Wikipedia

Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated, although there are exceptions. In geology, the term "marble" refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.

Quartzite - Marble & Granite

Quartzite is extremely popular due to its marble-like appearance and granite-like properties, which make it an ideal choice to be used in kitchens. Hardness of quartzite makes it extremely resistant to water absorption, heat, & scratches. Care Instructions: Use a stone sealant for an additional layer of protection.

Moh's Scale of Hardness - Marblecare Ltd.

The Moh's Hardness scale is not a linear scale unlike the scale of absolute hardness. So Orthoclase at 6 is not twice as hard as Calcite at 3, nor is the difference between talc and gypsum the same as the difference between Corundum and Diamond. An absolute hardness scale gives a clearer idea of how hard the minerals are in relation to each other.

Dolomite: A sedimentary rock known as dolostone or ...

Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Dolomite and limestone are very similar rocks.

Mohs scale of mineral hardness - Wikipedia

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. 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.

Mohs Scale of Hardness | Pohaku Fabrication Kauai

The Mohs Scale of Hardness was created in 1812 by German geologist/mineralogist Friedrich Mohs. This method of hardness judgement is based on the ability of one sample of matter to scratch another. So a mineral ranked 8 out of 10 is harder and will scratch a mineral ranked 3.
