Granite And Marble Price Distinction

1. According to the cause of stone:

Marble is a metamorphic rock, another stone naturally degraded by a stone under the influence of high temperature and high pressure and minerals. The qualitative change may be recrystallization, texture change or color change. Natural marble is a metamorphic rock formed by the original rock in the earth’s crust through high temperature and high pressure in the earth’s crust. It belongs to medium hard stone and is mainly composed of calcite and dolomite. There are usually obvious patterns and many mineral particles.

Granite is a igneous rock that is mainly formed by volcanic materials such as magma. The liquid magma under the surface is cooled and solidified. Mineral gases and liquids penetrate into the rock to form new crystals and various colors. Generally dark colors. Natural granite is igneous rock, also known as acid crystalline plutonic rock. It is a kind of rock widely distributed in igneous rocks and belongs to hard stone. Granite

2, According to the hardness difference:

Marble: Because marble generally contains impurities, and calcium carbonate is affected by carbon dioxide, carbide and water 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 white marble and Ai Yeqing can be used outdoors, and other varieties are not suitable for outdoor use, and are generally only used for interior decorative surfaces. The Mohs hardness is between 3 and 5.

Granite: Granite is harder than marble and is difficult to process, but resistant to acid and weathering. It is not easy to weather and deteriorate, and its appearance and color can be kept for more than 100 years. Therefore, it is mostly used for wall foundation and exterior wall finish. Granite is also used in high-rise building renovation projects due to its high hardness and wear resistance, for example, the floor of the lobby. The Mohs hardness is 6-7.
