Crystal stone or porcelain stone is one of the limestone or dolomite stones that undergo changes in their structure and recrystallize due to exposure to high pressure and temperature conditions. For this reason, they are classified as metamorphic rocks. In fact, it can be said that Chinese stones are in the category of marble stones. Marble stones can be very different by having different chemical compositions and the degree of transformation.
Crystalline marble is one of the most high-quality and durable building stones. In our country, there are many porcelain or crystal mines in different regions of the country. Among the most famous crystal stones of the country, we can mention Azna porcelain stone, Aliguderz, Niyriz, Qorveh, etc. The origin of Saiman porcelain stone is Qorve stone mines located in Kurdistan province.

Ghorreh Crystal Marble is used in many different cases due to its appearance characteristics and very suitable structural parameters. Qorveh porcelain stone, which we know as Saiman, is one of the most beautiful and newest types of porcelain stone, whose most important features are its exemplary strength and the ability to create bookmatch and formmatch frames, which has led to a significant increase in the sale of this stone.
For slab processing, export coupes with large dimensions (single coupe) are needed and the processing steps must be done carefully so that the stones do not break. The dimensions of the slab sheet sometimes reach 3 meters in length and 2 meters in width. The size of the slab sheet also depends on the size of the slab and the dimensions of the stone cube purchased from the quarry. In addition to the large size of the raw cup, the health and absence of fractures in the cup causes the extraction and processing of good and large stones.
Ghorreh Crystal Marble has very high strength and its density is also very suitable. Therefore, the proper absorption and polished and shiny surface of this stone is not far from the expectation. The very low water absorption of Saiman Qorve white porcelain stone has caused this stone to be used in many spaces that are exposed to moisture and direct contact with water, and moisture does not affect the health of this stone.

Ghorreh Crystal Marble in the form of book match
In the book matching operation, which includes two parts (book match) and four parts (formach), the cutting and processing of the stone is done in such a way that the natural lines and veins in the slab stone are placed along each other or in symmetry with each other. That is, like a butterfly or the patterns of a carpet that are in symmetry and extension of each other, the shawls and stone veins are paired next to each other.
Due to having many lines on its surface, Saiman’s Chinese slab stone has a very good matching ability when cut by the bookmatching method and provides the possibility of forming bookmatch and formmatch frames. For this purpose, in addition to the use of parallel designs on the floor and the internal and external walls of the building, this technique is used in the design of the bookmatch duplex stairs, which can be implemented in a simple and boxy way.
Currently, with the advancement of technology and the use of modern tools and devices, stone processing in the form of bookmatch and formmatch slabs is increasing day by day, and on the other hand, the use of these types of stones in new methods of building interior design is increasing. Therefore, book match and form match stones such as crystal or porcelain, marble or onyx, traonix and many marble stones are used in luxury and luxurious buildings and projects.

The uses of stone slabs are increasing day by day, and large sheets of stone in maximum dimensions are used more often. Stone processing in the form of slabs is different from the old methods in the form of peak cutting, and a saw is used instead of a single or thirty-bladed machine. In the cutting blade cutting method, the cutting operation is done on the stone in a rotary way, but in the slab method, the stone is cut in a reciprocating manner.
Currently, stone processing in the form of slabs can be applied to many stones, and if the steps of cutting, subbing and calibration are carried out correctly, slabs can be used in different spaces. In addition, in the slab processing method, the strength of the stone is increased compared to the old methods and the life of the stone is increased.
