Advantages and disadvantages of marble:

Advantages:

1. Natural marble is dense but not hard, and easy to process, carve, polish and polish. Marble is smooth and delicate after polishing, with natural and smooth texture and high decoration. Marble has low water absorption and high durability, and can be used for 40- 100 years.

Natural marble has fine texture, firm texture, smooth as a mirror after polishing, and the texture is more relaxed and beautiful than granite. The compressive strength is higher (second only to granite), which can reach 300MPa according to different rock strata. It has the characteristics of low water absorption, wear resistance and no deformation.

Disadvantages:

1. Because marble generally contains impurities, calcium carbonate is easily weathered and dissolved by carbon dioxide, carbide and water vapor in the atmosphere, and the surface quickly loses its luster. Therefore, a few stable and durable varieties, such as white marble and Ai Yeqing, have pure quality and few impurities, and can be used outdoors, while other varieties are not suitable for outdoor use and are generally only used for indoor decorative surfaces. The main varieties are: cloud gray marble, colored marble and so on.
