2.The composition of quartz is the simplest silicon dioxide, with glass luster, no cleavage surface, but shell-like fracture. Microcrystalline quartz is called chalcedony, agate or jasper. Pure quartz is colorless, but has different colors due to impurities often containing transition elements. Quartz is very stable and not easily weathered or changed into other minerals. According to the crystalline degree of SiO2, it can be divided into crystalline single crystal quartz and polycrystalline quartzite jade.
3. The higher the content of quartz in the quartz stone, the lower the resin content, the better the quality, the closer to the nature, and the less easy to deform. When the content of resin in quartz stone is more than 10%, its corresponding technical indicators will drop accordingly. At this time, quartz stone can no longer be called real quartz stone.
