★ Granite is very hard with coarse particles on its surface. It is mainly composed of quartz, orthoclase and ordinary mica. Granite occurs on all continents. Some of them belong to the oldest stones in the world. 6,000 years ago, people began to use granite. It is said that as long as there is granite, there is no place to be new.
★ Granite is beautiful, durable and very hard. In ancient times, with the current mining and processing equipment and technology, it was definitely more popular than marble.
★ Granite often contains other minerals, such as amphibole and mica, and presents a variety of colors, including brown, green, red and common black. Because its crystallization process is slow, its crystals are intertwined one by one like a Rubik's cube, so it is hard. It is as durable as a house. Not easy to scratch. It is not afraid of high temperature. Whether it is color or light, as long as you have a little common sense, you will not fade or shine.
Granite is also affordable. Fortunately, with the emergence of new mining, cutting and polishing methods, the cost of granite has been greatly reduced in the past few decades. Today, the price of granite can compete with low-cost artificial stone, which is more durable than anything else.
More importantly, granite will not pollute the environment. Synthetic materials are often accompanied by bad or even toxic by-products. It needs to be replaced several times during the service life of the building (there are always handling problems). Granite doesn't need to be replaced because it is very durable.
In addition, granite is very practical. Can be made into various surfaces-polishing, matte, fine grinding, fire, water spraying, sand blasting.
★ Natural granite is igneous rock. It is also called acid crystalline plutonic rock. It belongs to hard rock. It consists of feldspar, quartz and a small amount of mica. Granite is compact in structure and uniform in overall structure. According to its crystal particle size, it is usually divided into [macrocrystal], [coarse crystal] and [fine crystal]. Its color is mainly determined by the color of feldspar and the distribution of a small amount of mica and dark minerals. Generally, it is gray, red and slightly strong. Beautiful two-tone spot patterns are characterized by fine and uniform texture, with star-shaped mica bright spots and sparkling timely crystals. However, the crystallinity of marble is poor, and there are few fine particles on the surface, but the patterns are round, tree-shaped or pulse-shaped, so we can distinguish these two kinds of stones accordingly.
★ China's granite mineral resources are also extremely rich, with large reserves and many varieties. According to the survey data, there are more than 100 kinds of natural granite in China. Granite used for architectural decoration is named because of its pattern, color characteristics and raw material origin. Among them, Juqing, Xueqing, Yunlimei, Jinan black, Jinan, Shandong, Sichuan Shimian, Shanggao Douqing, Guangdong Zhongshan Zhongyu and Shaanxi Ling are better.
