High-quality quartz stone with a selection of natural quartz crystal minerals, the SiO2 content of more than 99.9% or more, and in the manufacturing process to purify, the raw materials do not contain any possible damage to heavy metal impurities, 94% of the quartz crystal and other The resin additive makes the quartz stone free from the risk of radiation contamination.
It should be noted that the quality of quartz stone is good or bad with the amount of resin has a direct relationship. Quartz stone in the higher content of quartz, the lower the amount of resin, the better the quality, the closer to the natural, the more difficult to deformation.

3:, 200 mesh sandpaper polished, easy to drop stone powder for the unqualified;
4, the cutting surface along the edge, there are cut and broken mouth for the unqualified;
5, the thickness of 15mm or more, 15 mm below the quartz stone will not be able to protect the bending performance;
6, whether the surface of the pores, there are holes are not good quartz stone;
7, splicing at the gap, not obvious for the good product;
