Quartz hardness and wear resistance are more superior to acrylic stone, good heat resistance. Either quartz or acrylic stone, can not be placed directly on the table, such as wok kettle multicolor quartz stone, the instantaneous temperature difference between the two materials will lead to the expansion and contraction Kai Sa produce local quartz stone, it will so that local internal stress generated burst changed greatly. Whether acrylic or quartz stone, if you do not use pot holders, can not be placed directly on the countertop hot objects. And the course of time, the area in contact with hot objects will light some of the other land areas and will produce light-colored countertop color difference. Quartz crystal is the nature of natural mineral hardness only to diamond identification of quartz, the surface hardness of Ta Mok's hardness of 7.5, much larger than the everyday use of knives and other sharp spade, even with a sharp knife across the surface, it will not leave marks. Up to 1300 degrees Celsius above its melting point, not because of exposure to high temperature caused by combustion, also with high temperature characteristics of the quartz content of other man-made stone unmatched.
