Azna and Aligodarz crystals
Porcelain (crystal) is mainly composed of two minerals, wollastonite and calcite. These types of rocks are limestone masses that have recrystallized due to internal factors, such as temperature and pressure, and their granulation is crystalline, which is visible to the naked eye; For this reason, it is called crystal and is considered as a metamorphic rock. Porcelain rocks vary in different parts of the earth in terms of metamorphism and chemical composition. Porcelain stone often has large crystals. These coarse crystals distinguish porcelain from sedimentary carbonate rocks. The use of porcelain stone for the use of facades and outdoor spaces is completely technical and correct.
Porcelain stone is not as absorbent as travertine or non-stick granite in terms of water absorption and adhesion of slurry. Porcelain is the main material of the facades of many old buildings, especially in the tropics, because its light color protects the building from high heat absorption. The weather resistance of this stone is moderately good and considerable, and in some mines, porcelain stone can also compete with travertine and granite.
This stone, like other types of stones, is offered to the market in different qualities, and the whiter the stone, the higher its price.
The cost of processing slab stone production is relatively twice the cost of producing longitudinal (tile) stones. The presence of this factor along with the naturalness as well as the eye-catching and unique appearance of large slab stone makes it more expensive than tile.
Crystal stone with its beautiful appearance, bright background and high variety has attracted many fans. In the stone industry, crystal is mainly found in the dark to light gray color spectrum with gray, black, and yellow streaks. The use of this stone has flourished significantly in recent years; Building engineers and architects use porcelain stone in building facades, stairs and staircases, floor stones in interiors such as lobbies, living rooms, bedrooms, bathrooms, countertops and cabinet stones.
The most important parameter of crystal stone quality is the physical and chemical analysis of that stone, and the closer the crystal stone analysis is to the desired level, the higher the quality and the higher the price.
Porcelain or crystal stone does not have much color variation, and the lighter and without streaks the stone is, the more popular and expensive it is.
Crystal or porcelain stones have different types that are sorted after cutting and sub-sorting. The more accurate and uniform the sort of stone, the higher the price.
The type of stone processing plays a decisive role in the price of crystal stone. Accuracy in cutting and angularity of the stone, the amount of sub and polishing of the stone and the type of packaging and transportation will affect the price of crystal stones.
The quality of crystal stone is very effective in determining its price, and sometimes the grade of similar super stones is less expensive than grade 2 of the same stone.
