Marble is another type of building rocks which belongs to igneous rocks and is very popular among customers and buyers. It is included in subcategory of Marbles in international markets.  It has apparently less pores tan travertine and also contain broader color spectrum which satisfies every taste. There are calcareous lines on the surface of marble that will be untouched after cutting and processing, and also considering the different resistance of marble stones, the experience has shown stones with clean appearance and fewer lines have less sturdiness than stones with more lines. It should be mentioned that this option is not for all types of marbles. Marble is ametamorphic rock based on calcium carbonate, and is formed from calcite, dolomite and crystals.The specific weight of marble is 2563 kilogram per cube meter and its resistance and stability is less than granite and greater than travertine.

Since marble stone which is produced for construction use will lose its resistance and change  to fracture, cracking on outer surface, discoloration and calcareous emptying   due to the explosion to climate change, it is highly recommended that use marble in indoors and away from rain, sunlight, and climate change. It is mostly used in interiors such as flooring units, interior walls. Marble with thickness of 3 or 4 is often used for interior stairs. The price of marble in international markets depends on 2 factors. First Natural property of marble and its appearance, second the quality of processed product. For this reason, two similar batches of stones might have different prices in two stores due to the difference in production and processing. One of the best properties of a qualified marble is low calcareous lines on the surface. The less lines on the surface the more sturdier the stone is.
