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.
Yule Marble - Wikipedia
Yule Marble is a marble of metamorphosed limestone found only in the Yule Creek Valley, in the West Elk Mountains of Colorado, 2.8 miles (4.5 km) southeast of the town of Marble, Colorado. First discovered in 1873—it is quarried underground at an elevation of 9,300 feet (2,800 m) above sea level—in contrast to most marble, which is quarried from an open pit and at much lower elevations.

Marble - University of Auckland
Hardness - hard, although component mineral is soft (calcite is 3 on Moh's scale of hardness). Colour - variable - pure marble is white but marble exists in a wide variety of colours all the way through to black . Mineralogy - calcite. Other features - generally gritty to touch.
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.
