 Marble can be used not only as a countertop, but also as a vertical wall background. This combination of marble and dark cabinets and stainless steel appliances creates a high contrast modern dream kitchen for singles. Since Dalian marble generally contains impurities, and calcium carbonate is exposed to carbon dioxide, carbides and water vapor in the atmosphere, it is also easy to weather and dissolve, and the surface quickly loses its luster. Therefore, a small number of relatively stable and durable varieties such as China White Marble and Silver Mink Marble can be used outdoors, and other varieties are not suitable for outdoor use, and are generally only used for interior decorative surfaces.

 Marble is formed by metamorphic rocks of sedimentary rocks and sedimentary rocks. The main component is calcium carbonate, which is about 50%-75% and is weakly alkaline. Some marbles contain a certain amount of silica, and some do not contain silica. Fine particles (referring to calcium carbonate), the surface distribution of the stripes is generally irregular, and the hardness is low.

 China's building stone products mainly include marble and granite. At present, the stone center has detected and collected the radioactivity detection data of more than 1000 kinds of stone in China. The radioactivity index of marble is about 0.02, similar to soil, only standard technical indicators. About 2%; the majority of domestic granite radioactivity is far below the standard index, with a large enough safety factor.
