Marble:
Marble has a more calcareous structure than travertine and therefore the use of marble in spaces that are close to moisture is not suitable. The distinction of marble from travertine can be distinguished from the back of the stone from the point of view of those who are not experts, with the explanation that marble has no pores and mostly has veins.

A traditional method that architects use to detect the solidity of marble is to hit the back of the marble with a metal object. The lower the sound from hitting the relative part of the marble, the denser the marble. Marble is mostly used in the interior of the building. Marble can be used in stairwell, parking lot, floor of building unit. In Iran, many marble quarries have been identified and are being exploited.
Bright marble is very popular for execution on the floor of residential units. Persian Silk marble or Emperor silk can be called marble with a gray background. Marble with brown colored background can be called Mahkam marble. Marble with cream colored background can be called Dehbid Shayan and Namin marble.

Marble with white background can be named as Sabzevar and Kashmar marble. Marble with black background can be called Najafabad marble, Golden Black marble, Dehbid black marble and Birjand black marble. Marble with red background can be named Bavanat marble, Anarak marble and Bajestan marble and the most important case called pietra gray marble which is known as lashotor marble from Isfahan queries located in the center of Iran.
The price of marble depends on several factors such as the thickness of the cut, the quality of the saw and cut, the materials used in processing, the accuracy of sorting, and the size of the marble produced. The larger the size of the marble produced, the higher the price due to the difference in the method of production and processing. among them, this type is the best choice with considering the suitable price and high quality.

  • Features of marble:
  • Variety in colors with the ability to execute different and custom designs
  • Very light. (It is lighter than other stones and has a specific weight of 1100 to 1300 kg per cubic meter, which reduces the weight of the building and thus reduces the effect of earthquakes on the building.)
  • Ability to absorb water to zero
  • No restrictions on production dimensions with installation such as granite
  • Endurance (tension and pressure) higher than existing decorative stones
  • Scooby is selfish. This means that unlike natural stones, due to atmospheric factors and lack of adhesion, it does not separate from the body of the building over time. (One of the most familiar disadvantages of natural stone is the gradual separation from the body of the building.)
  • High resistance to atmospheric factors
  • High strength and cohesion
  • High diversity
  • Easy and hassle-free installation

pietra grey marble:
pietra gray marble is the same as marble, but with a different gender and design and degree from the original marble. pietra gray marble is a stone that is processed in black with sometimes white streaks. pietra gray marble is very hard and also used in many cases in factories and then it is cut by hand or with an ax, which is called pietra marble or Lashotor marble with a machine ax.

The reason why pietra gray marble is axed is that due to its hardness and also its use in open environments, with this method, the friction on pietra gray marble increases. it can be used in projects as a sentence, plate and size. Grinded is processed as pietra gray slab marble due to its color (black) in some factories.
According to the order of the contractors and builders of the project, pietra gray marble is divided into 2 types: low-axed and sharp-edged.

The word “marble” derives from the Ancient Greek mármaros meaning crystalline rock or shining stone.   This word is also the ancestor of the word marmoreal meaning marble-like.

In fact, to make a crystalline rock, limestone must be subjected to a lot of pressure for a long time. In appearance, marble is more appealing than limestone. It is used in the constructing of buildings. Thera are some interesting facts about marble:

There are many applications in using the marble in the building construction. But mainly it is used in the bathroom and countertops. The various colors of marble for bathroom units and walls, give the bathroom a warm surrounding. Marble can also be used for the floor but the polished surface of the marble is slippery. In that case, the honed marble is recommended. Additionally, marble can be used for fireplace surrounds, tabletops, reception countertops, floor tiles, exterior applications such as braai areas, jacuzzi and pool surrounds, and countertop. T

The use of marble for the countertop gives a kitchen a smooth, soft, luxurious look. It can be a good substitute for a granite countertop. Since it has very good resistance to high heat. you can directly put hot pots on the surface. Unfortunately, due to the soft nature of the stone, marble can scratch. The stone is also porous and will stain if spills are not wiped up quickly.

Marble Stain Resistance 

although marble is very vulnerable to stains and scratch easily, using a penetrating stone sealant can solve this weakness. Sealing the surface will definitely affect the quality of marble to be resistant to the scratches and stains. The sealing can penetrate in the small and microscope pores of the stones and it is what has been done by the stone installers. If the marble got the stain, it can be cleaned and the stain is easy to be removed after sealing.

Marble Chemical Resistance

Marble reacts quickly to acids like fruit juice, coffee, soda, alcohol, salad dressing, etc.). such liquids can etch the surface of the marble. Such etching can destroy the polished surface of the marble and remain a stain. the acid that exists in the rain can destroy the surface of the marble-like other kinds of acid liquids. Therefore, it is clear that Acid rain, pollutants, and other weathering elements can affect the surface of exterior marble installations.
