Quartz is composed of the simplest silicon dioxide, glassy luster, no cleavage surface, but with a shell-like fracture. Microcrystalline quartz is called chalcedony, agate or jasper. Pure quartz is colorless, but it shows different colors because of impurities often containing transition elements. Quartz is very stable and not easy to weathering or change into other minerals. According to the crystallinity of SiO 2, it can be divided into single crystal quartz and polycrystalline quartzite. Gloss: Glass gloss. Colour: No, white, with a little gray, yellow to orange, purple, deep purple, pink, grey brown, brown, black. Stripe: White. Specific gravity: 2.65 ~ 2.66. Category: Metamorphic rock, metamorphosed from sandstone.

The main material of quartz stone is quartz. The combination of rich colors makes it have the texture of natural stone and beautiful surface luster. Quartz stone countertops have various colors. Gobi series, crystal series, marble series and flash series have more characteristics. They can be widely used in public buildings (hotels, restaurants, banks, hospitals, exhibitions, laboratories, etc.) and home decoration (kitchen countertops, wash tables, kitchen and toilet walls, dining tables, tea tables, window sills, door covers, etc.). They are non-radioactive pollution and repeatable. New environmental protection and green building interior decoration materials. It should be pointed out that the quality of quartzite is directly related to the content of resin. The higher the quartz content in quartzite, the lower the resin content, the better the quality, the closer to nature, the less difficult to deform. Experts pointed out that when the resin content in quartzite is more than 10%, the corresponding technical indicators will be reduced. At this time, quartz can no longer be called real quartzite.
