Natural stone in accordance with its generating factors derived from many types, is currently used for building materials is more common sandstone, marble and granite.
1, sandstone:
Sandstone is a sedimentary rock, loose stone thick loose, may be loose when the moisture deformation; but with a unique rough rough texture, close to the natural feeling of rough forests, it is more often used in wall decoration.
2, marble:
Marble is a carbonate metamorphic rock, the original lime mud is slowly deposited on the seabed, crystallization and become limestone; in the case of vibration by the high pressure and high temperature changes, the most significant is the crystallization of the hardening, the formation of the so-called marble . Its texture due to the impurities contained in the generation is not uniform, and the formation of the formation of more active large-scale totem changes in the sense of the formation of natural marble as the landscape pattern. Ordinary life of 150 years.
3, granite:
Granite is a igneous magmatic rock, is due to the formation of the surface of the rock, sand and gravel by weathering, slowly moving to the bottom of the deep trench, again and again crustal movement, and slowly swallowed them to the center of the earth and was ultra-high temperature melt. Since the magma density is lower than the surrounding rock, it is gradually pushed up, after cooling to form a new 3-D crystal (igneous rock). But also because it is 3-D crystals, so the texture is smaller, three-dimensional pattern and the crystallization of the feeling, and even some granite in the light irradiation, will emit a dazzling shiny glitter. Its main components are feldspar, quartz and mica, the general durability of 200 years.
Other characteristics, the marble is limestone, lower than the hardness of granite, is also not resistant to acid erosion, it is not suitable for outdoor, in the long sunshine and rain erosion easily deformed, corrosion; and granite hardness High, and acid, so most of the laying outdoors or frequent public space.
In summary, the general choice of home interior stone mostly marble-based, in addition to cheaper prices than granite, the organization of fine, polished, wide variety, there are more patterns, color and other characteristics of the choice of space Consumers and interior designers love the important factors.
