Many quartz suppliers are speaking highly of their quartz slab quality. They point our many advantages of their quartz products. Here, I want to say something about bad quality of quartz stone. Firstly, bad quality quartz slab will bend sometimes, even before installation. That is because it contains too much resin or has no enough time of solidification. Besides, bad quality quartz slab has some breaking line at edges or backside, because there is not enough materials in the compressing process. Moreover, sometimes, you see quartz slabs is not flat at backside, also because of limited raw materials in the production process. Finally, on quartz surface, the slab grain is not average, because of immature production skills of workers in factory.
