Chinese rock
Crystal stone, whose old and colloquial term is Chinese stone, is one of the oldest building stones. So, if you look at the old namestone buildings, you will notice their abundant use in the exterior of the houses. Almost porcelain and granite stones were among the first stones extracted from mines that were used in building construction. Today, this stone is known as crystal stone, in fact, the Chinese name is derived from the idea that when a blow is made to the thin stones of this stone, the sound produced by it is similar to porcelain, of course, this stone is white marble in the world. It is called
The most famous crystal stone or white marble in the world is Carrara stone, which is extracted from Italian mines. Now, the point that we have encountered today is its less use and replacement of stones like travertine. The reason lies in the answer to the question of what is Chinese stone. Therefore, in the following, we will introduce this stone completely.
What kind of stone is porcelain?
Crystal stone is one of the metamorphic stones in such a way that limestone or dolomite stones are transformed by being subjected to heat and pressure, and as a result, porcelain stone is created. In this way, since marble stones are also formed from the transformation of limestone, porcelain stone is also considered as a family of marble stones in such a way that a separate category is not considered for this stone in other countries and as stated It is known as White Marble.
Now, the question that may arise for you is, what is the main reason why a separate category has been considered for it? The answer to this question lies in the difference between Chinese stones and crystals. In fact, the only difference between these two types of stones is the size of their crystals. Porcelain stone has coarse crystals and they usually exist in bright white color themes and has a very low color variation, while marble has a high color variation.
Appearance characteristics of crystal stone
One of the disadvantages of porcelain stone is its low color variety, and it is usually in bright white colors with halo, shawl and gray, black and sometimes yellow streaks, which changes according to the type of minerals. In fact, the main mineral of its composition is calcite, which is pure white, and in the presence of carbonaceous minerals, light gray to black colors are formed in it. Yellow colors are also caused by the presence of limonite mineral. White porcelain stone is the main type of porcelain stone.
Features of crystal stone
As mentioned, the main mineral of porcelain stone is calcite. Now, there may be another mineral called quartz in some of them, which adds to the hardness of the stone. In fact, the stronger and harder the crystal stone is, the more quartz minerals it contains. In general, Chinese stones are between marble and granite in terms of hardness. In the sense that it is not as hard and resistant as granite stones and it is stronger than marble stones.
Among its other merits is its very small porosity and its very low water absorption. Therefore, its adhesion to the mortar is low. In fact, in terms of adhesion, it can be said that it is between travertine and granite.
Also, this stone has high sandability and abrasion resistance and is resistant to weathering.
Crystal stone processing
After extraction from the mines, the crystal stone cup is transferred to the processing factories, where it is cut into different dimensions, which today is mainly in the form of slabs. Chinese stone slabs give a unique beauty to the space. Of course, according to the type of application, it is also cut lengthwise. Also, since this stone has little porosity and has good density and strength, it doesn’t need mesh and resin.
One of the most common payments that are made on it is the polished and axed payment. Lybid crystal ax stone is one of the most widely used building stones.
Application of porcelain stoneware
According to the characteristics of this stone, the uses of this stone can be described as follows:
- Chinese stepping stone
- Floor crystal stone
- Internal and external masonry of the building
- Plinth stone
- Stone and decorative artifacts
- Cabinet and countertop stone
- Toilet threshold stone
