The use of Azna porcelain stone in building, which is limestone or dolomite, is very high. A stone whose particles and minerals have endured the pressure and heat underground for hundreds of years and recrystallized. This stone has been metamorphosed and combined with other minerals.

Azna porcelain is the most famous Iranian crystal stone, which was first used by the late Haj Qanbar Rahimi known as Arbab Qanbar. Azna porcelain stone is also known as Arbab porcelain stone. It can be seen in Azna porcelain stone with a white background with gray and black irregular diagonal lines.
The crystal material of this stone has a very good shine. so that it has a very good light reflection. And despite the excellent analysis, it is considered one of the best crystal stones in Iran and the world. This stone is classified based on gray and black density. With a clean and clear background, it’s great for low-light situations.
Other types of Azna porcelain stone have similar transparency and beauty. With the only difference, the color of the background is darker or more lines and brightness and transparency are the most important features of Azna stone. If the abrasive of this stone is of good quality, it increases the transparency of Azna porcelain stoneware.
In fact, Chinese stone is a family of marble stones. which are different in different places in terms of degree of transformation and some chemical compounds. Porcelain often has large crystals. These coarse crystals are characteristic of porcelain stoneware from sedimentary carbonate stones.
In the past, due to the lack of proper technology, these stones were produced in small formats like tiles. But nowadays, these stones are produced in the form of slabs and with proper processing in the form of book matched (symmetry to one of the transverse or transverse axes) or four matched (symmetry of both axes).
Natural stones such as Azna porcelain are processed in the form of slabs, tiles, steps, longitudinal, etc. Azna porcelain stone is one of the most widely used types for use in different parts of the building. This stone has been used in Iranian homes for a long time, but due to the lack of modern technology, it can only be used in small sizes.
In the past, blasting methods were used to extract these stones, so there was little potential for yield. But now, using the latest technology in the world, it can be extracted from mines better than in the past. Natural stones such as Azna porcelain are processed in the form of slabs, tiles, steps, longitudinal, etc.

Azna porcelain stone slabs bring grandeur to your building. And because of the high price, it is mainly used in very luxurious and expensive buildings in the form of slabs and book-matches, which attracted the attention of designers and builders.
Azna porcelain stone mine
Azna porcelain mine is located in Azna city, Lorestan province, near Durood city. This mine is located 24 km from Durood city. The extraction method is done raw or in pieces, and after being transferred to a special factory for processing porcelain stone, it is made into slabs or tiles.
During the stone processing process, the surface is polished and covered with epoxy or resin. In this way, the life of the stone is increased and the possibility of water penetration, scratches and damage to the stone is reduced. Azna slab stones are also exported in cubic form. But for internal use, after processing, it comes in the size desired by the customer and is sold.
Principles of stone and ceramic cleaning
It is very difficult to clean stone floors and wall coverings due to the bumps and unevenness of the stone. It is recommended for natural stones such as slate in countertops and floors. Penetrating putties should be used once every two years. To prevent deep stains.
Clean stone tiles with a few drops of dishwashing liquid and warm water using a soft cleaning tool such as a sponge or soft cloth. For stubborn stains and dirt left from soap, clean with half a cup of ammonia dissolved in a gallon of water.
last word
In the end, all the stones can be produced in the form of book matched and four matched and with different processing and they have many uses for countertops, pool surrounds, exteriors, floors and internal bodies, etc. The only very important point about these stones is that the quality of their epoxy is good so that they do not turn yellow after being exposed to the sun.

In response to the question of what is Block, we must say that Block is not a special kind of stone, but it is a stone that is extracted directly from the mine, from the heart of the mountain. Slab stone is removed.

Block does not have a specific type in terms of gender, and all types of stones that are extracted from the mine are initially in the form of Block.

Therefore, Block can be made of granite, marble and travertine. But the classification of all kinds of Kop stones is done based on its size and quality. In this category, there are a total of three types of Kop stones:

One Block

Block, one Block stone is of high quality because it has no cracks or scratches and its color harmony is high. The dimensions of the single Block stone are large and its shape is cut in a hexagonal shape. The weight of a single cup stone is 25 to 27 tons. Due to its dimensions and high weight, each single piece of rock is transported on a trailer.

Two Blocks

The dimensions of the double Block stone are smaller than the single Block stone. In fact, two stones and two Blocks are equal to one single Block. Two Blocks  are usually in the shape of a rectangular Block, but they may not have a special shape. Two stones can be loaded on a trailer.

Three Blocks

The dimensions of three Block stones are smaller than two Block stones. In fact, all three Block stones are equal to one single- Block stone. Therefore, in transportation, three pieces of stone, three c Block, are transported on one trailer.

Block stone measurement for cutting is done in the mine. It means that the stone can be cut from the raw stone in the mine to the desired amount and its dimensions are not fixed. Of course, it should be kept in mind that the value of a stone depends on its dimensions; The bigger the stone, the more valuable it will be. If the size of the stone is large, the stone cutting factory can easily cut it into pieces with the required dimensions.

Block stones are usually cut into 4-sided or 6-sided shapes and are cut into smaller pieces based on their shape at the stone cutting plant. In this way, the Block stones, which have a regular shape and are in the shape of a square Block or a rectangular Block, are cut into slabs with a saw.

But for cutting stones with irregular geometric shapes and generally stones that cannot be cut with a saw, the top is used. These stones are cut into square tiles with side sizes of 30, 40, 50, 60 and 80.

Block stone or block stone is a stone that needs processing and cannot be used without processing. Slabs are made from Block-shaped stones with large dimensions, and tiles are made from stones with irregular shapes and smaller dimensions.

The result of this processing, whether it is a slab or a tile, will be used in various fields, including construction, interior decoration, and making decorative items.

Why are stones cut in the form of a Block?

There is no other way to use mineral stones except cutting and extracting the stone in the form of a Block from the mine. The best way is to cut the stone in large pieces so that the best processing can be done on the stones and the required pieces can be prepared from them as desired.

For this reason, the stones in the mines and in the heart of the mountains are cut in the form of cut stones, and then they are transported to the stone-quarry factories for the next operation and preparation for consumption.

Block stone cutting tool

Block stone cutting tool depends on the type of stone. Usually, the best tool for cutting stone is a saw with a diamond blade, but if the desired stone is a hard stone like granite, we need stronger tools for cutting. In these cases, steel and cast iron chips are chosen to cut the Block.

Also, when the Block is transported to the stone cutting factory, according to whether its shape is regular or irregular, the relevant cutting operations are performed on it.

A saw is used to cut a regular Block, and if the Block does not have a regular geometric shape, it is cut with a peak and made into a tile shape

Among all the materials, stone is a material that has been used in the facade of the building since the past until today, and its durability and high resistance are always mentioned. The facade stone must be without cracks and breaks and not porous, because the exterior is one of the important parts of the building that is exposed to various factors, as a result, if there are cracks or voids, dust and Or rainwater penetrates into it and erodes quickly.

A good stone should have the necessary resistance against water penetration and should not be damaged due to exposure to chemical and natural environments. Most of the people who buy face stones only rely on the recommendations of others and will eventually feel dissatisfied with the passage of time. One of the ways to distinguish a good stone from a bad one is to give it a few hits with a metal tool. throw a stone A quality stone without cracks is a stone that gives the sound of glass, so if the stone emits the sound of glass due to impact, it will undoubtedly be a healthy stone without cracks or decay.

Types of facade stone

The stones that are chosen for the exterior of the building must have high durability and strength. Facade stone is always exposed to sunlight, snow and rain, dust, pollution, cold, heat and humidity, for this reason resistant stones are the best option for facade. Next, we will examine the types of facade stones.


Granite is a type of igneous rock and is available in various colors. This stone has a coarse texture and can be easily seen with the eyes. Granite does not absorb pollution and has high hardness. Granite can be used not only on the exterior, but also in wet indoor environments such as bathrooms and toilets, because its porosity is low and it does not absorb water. According to the minerals in it, granite can be seen in gray, green, red and pink colors. Black granites with large feldspar grains or leopard granites are also considered as types of this stone that have a high price and are usually sold in large pieces.


Travertine stone, which is a type of sedimentary stone, has a layered texture. This stone has high adhesion and due to its layered structure, it can be cut by cross cut and vein cut methods.

Compared to other facade stones, travertine is cheaper and has good resistance. In addition, this stone adheres well to cement and there is no need for scoping. Wavy travertines are more expensive than the cloudy and windy ones. Gray, tan and beige travertines or a combination of these colors have a higher price due to the beauty and uniqueness of the design and color.


Marble is one of the most beautiful and expensive stones. Because of the high price, this type of stone is rarely used in the facade, but if you have enough budget for facade, the best and most resistant stone for the facade is marble.

Marble is available in beautiful colors such as green, yellow, and white, and is used in facades of shrines, mosques, hotel lobbies, and luxury buildings. This stone is highly resistant to weathering, gases and acid rain. This stone appears beautifully in the facade of the building and other decorative elements of interior decoration.

Sand stone

Sandstone is one of the sedimentary rocks that consists of sand and various minerals. The minerals in this stone include silica, iron oxide, calcium carbonate and dolomite. Sandstone has a high resistance to weathering. The adhesion of this stone to the mortar is very low, that’s why when using it in the facade of the building, a stone scoop clamp is used. The color of sandstone is grayish brown and yellow. Due to its sand structure, sandstone has a rough texture and does not absorb well. This type of stone absorbs water and its low bending resistance makes it easy to bend.

Stone in architecture and its role in the facade of the structure

Perhaps the most important role of stone in architecture is its role in designing the exterior of a structure. For the design and construction of the exterior of the building, durable, resistant and attractive stones are used, which are resistant to various natural and environmental factors and are not easily damaged. Environmental factors such as cold and hot weather during the day and night, direct sunlight, snow and rain, strong winds and things like that can cause the destruction and disintegration of a stone and cause problems for you. One of the other influential factors in the choice of stone in exterior architecture is the location of the structure. Depending on whether your structure is in a cold or warm region, different stones can be used. For the facade of the building, high-quality stones should be used, which have the ability to resist natural factors and can meet the needs of the people inside the building during the useful life of the structure.

Interior architecture with stone

Stone is a suitable option for interior decoration of buildings and home decor architecture. In addition to its good appearance, it has high resistance in the structure. In interior architecture, stone is used to decorate the main wall of the house, fireplace, columns, window side, behind the TV, etc. Decorative and luxurious stones in these spaces play the same role as wallpaper and wall posters.

Stone in the interior wall coverings of the building

High-quality and beautiful stones for the interior walls of the building give it a stylish and modern effect. Stone is the best option for the walls of the bathroom (toilet and bathroom), kitchen and corridors. The stone used for the wall of these spaces should have a polished and polished surface in addition to a beautiful appearance. Also, these stones should be resistant to acid and detergent.

The use of stone on the floor of the building

Stone is the best option for covering the floor and stairs of a building. The stones that are used for the stairs must be able to be cut to the required sizes. These stones are exposed to pollution and blackening more than other stones in the building, and therefore, they should be resistant to detergents and disinfectants and not suffer from problems. One of the best stones that can be used in stairs and building floors is quartzite stone.

Use of stone for walls

One of the methods that can be used to reduce decoration design costs is to use cheap and simple stones for wall covering. These stones can be stones that exist in the natural environment around you or can be bought ready-made in the market. By installing stones in the walls, if there is a gap between them, fill this gap with the help of smaller stones. Limestone and sandstone are two great materials for your wall.

There are different types of building stones and each of them has unique characteristics that are used in different parts of the building. In this article, we mention 4 types of stones that are widely used in the building. The following stones are placed in the category of travertine, marble and porcelain stones.

Salsali Stone

Salsali stone is from the family of marble stones. High strength, reasonable price and eye-catching beauty have made this stone one of the most popular building stones in Iran and it is used in many buildings and places. Considering that this stone is from the family of marble stones. It is better not to use it in the external spaces of the building where there is a possibility of rain and frost

which may cause weathering or cracks on the surface of the stone if used Use it longitudinally in the body of the parking lot and staircases, etc. Of course, in outdoor spaces, you can use stone with greater thickness, or in the form of stairs, or premium Salsali marble that has fewer veins and is more resistant to cold and frost. The mine of this stone was located in the city of Khor and Biabank, Isfahan, for this reason, this stone is also known as Khor marble. This stone is mostly used in internal walls, floors and internal stairs. To use this stone outside the building, it is better to choose the premium grade. Premium stone has a higher resistance due to having fewer lines.
