Marble is a kind of natural stone that is not as hard as granite. Marble is also known as the metaphoric rock that is formed from limestone which has been crystallized overtimes. In fact, marble is a kind of crystalline rock concluding one or two of the materials like calcite, dolomite, or serpentine. Marble is white in its purest form. The interesting pattern of color and pattern in marble highly depends on the number of mineral materials in the structure of the stone.
It is extracted from the quarries in large blocks that are cut in the form of slabs with different kinds of finishes. Marble is considered as the kind of luxurious natural stone around the world that is used mostly for countertops, stairs, etc. Marble is resistant against stains and scratching. It is also used in decoration.
The Formation of Marble
Marble is made from a combination of limestone and dolostone gradually over time due to heat and pressure in the earth’s crust. Generally, marble is referred to as a crystalline rock composed predominantly of one or more of the following minerals: calcite, dolomite, or serpentine. However, not all marbles are the same. Varying amounts of minerals present in the limestone during re-crystallization affect the mineral composition of each marble that forms, contributing to the interesting array of colors and patterns.
Marble is mined from quarries around the world in large blocks that are then cut into slabs. These slabs are polished and distributed to stone suppliers. Stone fabricators purchase these slabs from the stone suppliers and install them in your home or office.
Marble Countertops and Durability
Marble has various durability range depending on the type of marble. Generally speaking, the black marbles like 3D black, Black Marquina, Najafabad, and Pietra Gray are harder and less porous. That makes them more resistant to scratches and stains.
To take care of the marble countertop, it is better to use the cutting board and no heavy object is put on top. To prevent any kind of stains on the surface of the marble countertop, the spills should be cleaned as soon as possible. Any kind of chemical cleaners used to clean the marble countertop must be confirmed by the stone fabricator to make sure it works on the marble surface and doesn’t destroy it.
Comparing to granite, marble is less resistant to scratches. That is why marbles are not used much Marble is a softer natural stone and does not have as high scratch resistance as granite.
Due to impurities such as clay or silt found in limestone, different colors of marble have varying scratch resistances. Comparing to granite with approximately 7 out of 10 Mohs in terms of hardness, marble scores a hardness rating between 2.5 and 5 on the Mohs scale. In terms of heat resistance, marble is very like granite. Even hot pots can be placed directly on the surface without damaging or discoloring the marble.
