Natural stone refers to the general term for the products that have been mined from natural rock masses and processed into blocks or plate-like materials. Natural stone used for building decoration mainly consists of granite and marble. The so-called marble refers to sedimentary or metamorphic rocks of carbonate rocks, marble, dolomite, limestone, sandstone, shale and slate. Then, the next small series for everyone to introduce what kind of natural stone and how to identify natural stone dyeing.

What are the types of natural stone

1. Sandstone

The sandstone is actually sedimentary rock, and the stone is coarse and loose, and may be loosely deformed when exposed to moisture. However, because of its unique concave rough texture, it is closer to the natural rough feeling between mountains and forests, so it is often used for wall decoration.

2. Slate

Slate is a rock with a plate-like structure and little recrystallization. It is a metamorphic rock. The original rock is muddy, silty, or neutral tuff. It can be stripped along the direction of the planking. The color of the slate varies with the impurities it contains. The ferrous color is red or yellow; the carbonaceous substance is black or gray; the calcium-containing case is blistered, so it is generally classified by its color. Green slate, black slate, calcareous slate, etc. Slate can be used as a building material and a decorative material. In ancient times, slate was often used as a tile in areas where slate was abundant. Slate usually contains no minerals.

3, marble

Marble is a metamorphic rock of carbonate type. It was originally deposited in the seabed and crystallized into limestone. When the ground is shaken, it is subject to changes in high pressure and high temperature. The most obvious is that the crystal becomes large and hard and forms so-called marble. . The texture of the texture caused by the generation of impurities is not uniform, and through the formation of the formation of a more lively large totem changes in the feeling of the formation of imitation of Foshan, the natural marble road. The average durability is 150 years.

4, granite

Granite is a kind of igneous magmatic rock. Because the rocks and sandstones on the surface of the stratum are weathered, they slowly move to the deep trenches on the seabed. Once the crust moves, they slowly swallow them into the center of the earth and are ultra-high temperature. melt. Because the density of the magma is lower than that of surrounding rocks, it is gradually pushed upwards, and after cooling, new 3-D crystals (igneous rocks) are formed. Because it is a 3-D crystal, its texture is small, the pattern has a three-dimensional and crystal feel, and even some granites emit a dazzling brilliance under light irradiation. Its main components are feldspar, quartz and mica, etc. The average durability is 200 years.

How to distinguish natural stone dyeing

1, dyeing stone color is beautiful, but not natural.

2. The level of dyeing and soaking can be seen at the fracture of the plate.

3, dyeing stone is usually used stone is not good, porosity, high water absorption of the stone, with the knock method can be distinguished.

4. The gloss of the same type of dyed stone is lower than natural stone.

5, coated with oil to add gloss to the stone on the reverse side of oily feeling.

6, the coating of the stone, although the gloss is high, but the film strength is not good, easy to wear, see the light scratches.

7, wax to add gloss to the stone, with a match or a fire to bake, wax surface that is lost, showing its original appearance.

Editor's summary: What are the types of natural stone and how to identify natural stone dyeing is introduced here, and I hope to help everyone. If you want to know more related information, you can pay attention to this website information.
