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.

Build quality and finish.
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
