What is the marble?
According to the intenational standard definition, marble is one of the types of metamorphic limestone that its main constituent is calcium carbonate, and it is composed of other components such as calcite, dolomite and crystal. Due to the presence of magnesium carbonate in the structure of marble, it is called dolomitic, calcite and magnesium marble. If the crystal in marble is small, Its polishing ability and resistance to weathering increase.
This type of building stone has less porosity than travertine, also its compressive and abrasion resistance is higher.
Veins formed on the surface of marble are due to the presence of minerals such as quartz, hematite, limonite and perite. As mentioned, one of the differences between marble and travertine is less porosity and higher compressive strength, but usually, non-specialists can hardly distinguish between these two types of building stone. One of the distinguishing marks of these two types of stones is the back of the stone. Unlike travertine, marble usually has no pores and veins are seen in this type of stone.

2- high thick stone should be used. Tehran Freedom Tower is an example of this type of application.
One of the tips to keep marble better for a long time is to protect the back of the stone from moisture and clearing dirt from the surface of the marble.
In addition, one of the most suitable places where marble can be used is the interior of buildings. A variety of colors, especially cream, gray, brown and black are suitable for this type of application.

Marble price
The price of marble in the market depends on several factors:
1. Number of stone veins: As mentioned, the fewer marble veins have made the higher strength of the stone and as a result, the price of marble rises.
2. Thickness and dimensions of the stone: The thickness and dimensions of the stone will play an important role in determining the price of the stone. The dimensions of marble indicate its solidity and texture strength. Therefore, the larger the dimensions of the marble have made the higher the price of the stone.
3. Processing quality: The processing quality of marble depends on the amount of sub, cutting accuracy, type of packaging and transportation, and type of resin used. In general, If the physical and chemical analysis of marble is closer to the desired level, this stone has higher quality and price.
4. Stone grade and sort: Stone sorting is done using advanced sorting machines. The more accurate and uniform the sort, the higher price.
5. Color and design of stone: Light colors of marble have a higher price due to the greater acceptance of designers and architects.
6. Stone mine: The stones extracted from different mines have different qualities. Bayat mine, as the largest gray mine in Iran, has the highest quality gray marble in Iran (Persian Silk or Silk Emperador).
7. In addition to the mentioned factors, the type of quality of the sub, the type of bites and the number of times of the sub increase the transparency and shininess of the marble, and as a result, increase the price of the marble.

3. To buy marble as a floor, its compressive strength should be 270 kg / cm for residential units, 500 kg / cm for commercial and office units and 900 kg / cm for parking lots.
4. Purchased marble must be free of cracks, grooves, fractures and rot.
5. Also pay attention to stone application. For example, if a stone with high water absorption is used for a place with high humidity, the stone will stain over time and change color and shape.

The colors on the surface of marble are generally due to the presence of impurities such as silica, mica, iron oxide, graphite and calcareous materials. Usually, Dense marble has low water absorption (about 2%) and lower density marble has high water absorption (about 4 to 12%).
Magnesium-containing marbles are more resistant than pure calcite marbles due to the presence of magnesium and the high hardness of magnesium carbonate in it (about 3.5 to 4). Therefore, most of this type of marble is used in stairs and exterior of buildings such as floors.
Resins, adhesives, and epoxies are commonly used to increase the strength and durability of marbles and have made to cover the pores in the stone and increase resistance to pressure.
One way to determine the density and solidity of marble is to hit the back of the stone with a metal object. If the sound is lower to the unsub part of the stone, this marble has a higher density.
Marble cutting is in the form of cutting wire and is produced in the form of tiles and slabs with a thickness of 18 to 30 mm, depending on the type of application.
