Difference between quartz and granite 
1, quartz stone is made of 94% quartz and 6% of the resin, the hardness of 7 degrees, and Engineered stone is marble powder and resin synthesis, hardness 4-6 degrees simple that quartz stone than granite hard, scratch-resistant, wear-resistant than him. 
2, look at the samples, granite surface with a protective film. Quartz surface without any processing. 
3, quartz can be reused, because within the quartz material is evenly distributed, so are basically the same regardless of whether they were positive or negative, that is to say the surface has been a serious collision receipt of the damage, the positive and negative after simple polishing and grinding can achieve the same effect as the original positive, thus greatly reducing maintenance costs and costs. Granite is not reused, because it has the positive effect is produced through a special, once damage is no longer spent. Simply means that quartz is not easily damaged, and easily broken granite. 
4, quartz is no radiation products, no adverse effects on the body; production of quartz raw materials are no radiation quartz; granite is made from natural marble powder, so there may be radiation to cause adverse effects . 
5, quartz due to the characteristics of its own material, determines its high temperature, temperature of 300 degrees Celsius is not its to have any impact, that is, no deformation and fracture; granite contains large amounts of resin, The phenomenon is particularly prone to deformation at high temperatures and performance charred.
