Q: How to classify natural stones?

A: The American Society for Testing and Materials classifies natural stone into six categories: Granite, Marble, Limestone, Quartz-based, Slate, and other stone materials.

Q: What is the name of natural stone?

A: Natural stone is named according to the color, texture, and origin, which reflects the decorative and natural properties of the material more intuitively and visually. However, the Chinese names of some natural stones are also very interesting, such as the Origin of Life, Trump Grey, Golden Spider, Obama Wood Grain, etc. These interesting names are designed to make it easier to remember to increase sales.

Q: Is the name of the stone related to place of origin?

A: In general, most of the stone names are related to their origin, such as Carrara marble from Carrara city in Italy, Brazil black from Brazil, etc.; but there are also special circumstances, such as Tan Brown Granite is produced in India, French beige is produced from Indonesia, etc.

Q: What are the main mineral components of stone?

A: As we all know, stone is made from the rock of the stone quarry. Rocks are made up of various minerals. The so-called minerals are the relatively stable natural products formed by various geological elements in the earth’s crust.

Q: What is the stone block?

A: It is mined by the stone quarry and has certain size specifications for processing stone slabs, carvings, and custom stone products.

Q: What is granite?

A: Granite is mainly composed of quartz, feldspar, and mica. The feldspar content is 40%-60%, and the quartz content is 20%-40%. The color depends on the type and quantity of the components contained. Granite is a rock with a full crystal structure. The fine granite has a fine and uniform grain structure, compact structure, high quartz content, and bright feldspar luster.

Q: What are the characteristics of granite?

A: The texture is hard, wear-resistant, corrosion-resistant, good strength, not easy to break, the ratio is large, the color pattern is generally uniform, regular, weak water absorption, difficult to bond, difficult to process, good gloss.

Q: What is the use of granite?

A: The use of granite depends on the size of the grain: fine grain can be polished or carved, as a decorative sheet or artwork; medium grain size is often used to build piers, bridges, dams, seaports, feet, foundations, pavements, etc.; coarse-grain rolling into gravel, is an excellent aggregate of concrete. Because granite is acid-resistant, it is also used as an acid-resistant lining and container in chemical and metallurgical production.

Q: What is the main chemical composition of marble?

A: Marble is a metamorphic rock of carbonate rock. It is mainly composed of calcite, limestone, serpentine and dolomite. Its composition is mainly calcium carbonate, accounting for more than 50%. The chemical composition is mainly calcium carbonate, accounting for about 50%. The above, there are also magnesium carbonate, calcium oxide, manganese oxide, and silicon dioxide.

Q: What is artificial stone?

A: Artificial stone is made of a non-natural mixture, such as resin, cement, glass beads, aluminum stone powder, etc. plus gravel binder. Generally, unsaturated polyester resin is mixed with fillers and pigments, and an initiator is added, which is produced through a certain processing procedure.

Q: What is the difference between quartz and quartzite?

A: Quartz stone is the abbreviation of artificial stone manufacturer for its products. Because the content of quartz, the main component of artificial stone, is more than 93%, it is called quartz stone. Quartzite is a natural mineral sedimentary rock, which is composed of quartz sandstone or siliceous rock. Metamorphic rock formed by regional metamorphism or thermal metamorphism. In short, quartz stone is an artificial stone, and quartzite is a natural mineral stone.

Q: What is limestone?

A: Limestone is referred to as limestone and carbonate rock with calcite as the main component. Sometimes it contains dolomite, clay minerals and detrital minerals, such as ash, gray, gray, yellow, light red, brown-red, etc., the hardness is generally not large, and the reaction with dilute hydrochloric acid is severe.

Q: What are the standard products of stone mosaic?

A: Stone mosaic standard products include six categories: mold mosaic, small particle mosaic, 3D mosaic, fracture surface mosaic, mosaic carpet, castle brick.

Q: Are the granites used outdoors?

A: When used for outdoor building decoration, it needs to withstand long-term wind, rain and sun exposure. Granite is suitable for granite stone because it does not contain carbonate, has low water absorption, and is resistant to weathering and acid rain.

Q: How is the difference between artificial stone and natural stone?


  1. Artificial stone lacks the naturalness of natural stone. Although artificial stone can artificially produce a variety of patterns, it is still not as rich and natural as natural stone.
  2. In addition to Engineered Marble, the reverse side of other artificial stone generally has a pattern.
  3. Bubbles are often found in artificial stone.

Q: What are the advantages of stone compared with other decorative materials?


  1. The main advantage lies in its natural, low-carbon and environmental protection; mining can be done without pollution and other processes.
  2. The stone material is sturdy and durable, and its hardness is second only to steel.
  3. The natural stone texture is unique and natural, without traces of artificial decoration. With the improvement of people’s living standards in China, stone has gradually entered the home improvement market and entered people’s side.

Q: What are the characteristics of marble and granite?


  1. Marble: Reticulated granules, soft texture, poor strength, easy to break, generally bondable, absorbent, easy to process, easy to fade, complicated pattern, endless change
  2. Granite: Granular particles, hard texture, good strength, not easy to break, generally can not be bonded, weak water absorption, difficult to process, long-lasting light color, uniform distribution of patterns
