Because marble generally contains impurities, and calcium carbonate in the atmosphere by the role of carbon dioxide, carbides, water, but also easy to weathering and erosion, and make the surface lose luster quickly. Therefore, a few, such as white marble, AI Yeqing, etc., which are relatively stable and durable and have less impurities, can be used outdoors, and other varieties are not suitable for outdoor use. They are generally used only for interior decorative surfaces. The main varieties are: cloud gray marble, color flower marble and so on.

Natural marble has fine texture and solid texture, polished and polished as a mirror, the texture more than granite stretch, beautiful. Compressive strength is higher (after granite), according to the different rock formations, up to 300MPa, water absorption is small, wear-resistant deformation and so on.
Radioactivity: In addition to the high requirements for the ruggedness and environmental friendliness of marble plates, marble furniture also has strict controls on the radioactivity of stone materials. For a long time, people have mistakenly thought that marble furniture will have radiation, and there are some concerns when buying.
