This white marble is a new mine and a new variety. species Many people may have seen the raw materials of white ash - limestone, which is derived from this ordinary gray stone. The "contributor" that turns limestone into marble is the hot magma in the ground. When the magma rushes into a large limestone rock formation, under the extrusion and baking of the magma, the calcium carbonate particles that make up the limestone become crystalline calcite, and the inconspicuous limestone becomes a smooth and beautiful marble with clear patterns. . Marble has a variety of shades and textures. The white marble is white marble. It is crystal white, contains glittering crystals, and is a very valuable building material. The pure white calcium carbonate rock is called white marble. It is mainly composed of CaCO3, MgCO3 and SiO2, and also contains a small amount of Al2O3, Fe2O3 and other components. Material reference parameters are: whiteness, gloss, compressive strength, flexural strength, Shore hardness, water absorption, density and so on. It is generally considered to be a sedimentary metamorphic deposit formed under the conditions of hydrothermal metamorphism and dynamic metamorphism under different conditions of carbonate formation under the influence of magmatic hydrothermal action. White marble is pure white marble, a limestone form. use The white marble is white and used for carving Buddha statues. The Western marble used white marble as a portrait carving material from ancient Greece. Since ancient China, this stone has been used to make stone steps and guardrails in the palace.

The white marble used by them is a kind of stone produced in the stone mine in the west of Gaozhuang Village, Dashiwo Town, Fangshan, Beijing. In 1998, the National Building Materials Bureau Stone Quality Monitoring Center and the China Stone Association rated 83 new special stones. Fangshan Gaozhuang Hanbaiyu was rated as No. 1101, known as “China No.1â€.
