1. Wear-resistance

Quartz stone countertops have high hardness, quartz stone is commonly made of quartz crystal and resin, and the quartz volume is about 93%, which makes quartz stone seldom gets crack and well wear-resistant. Bad quality quartz stone has high volume of resin, low hardness and easy to scratched. When you want to buy it, you can use a small knife to cut the surface to check its wear-resistance.

2. Chemical test

To get the highest profit, some manufacturers will mix some calcium carbonate in the quartz materials, which is easy to respond to the acid. Once you use such kind of countertops for a long time, the surface will be out of shape. While you can get one sample and just make a small chemical test when you want to buy quartz surface.

3. Pollution Seepage

The surface and inside of superior quality quartz stone slabs are delicate and uniform. Low water-absorption and strong anti-seepage. When you select the quartz surface, you can drop some soy one the surface to check its seepage, the soy will seep the surface after one day, while the high quality quartz surface will not.

4. Heat-resistance

Composed of high volume of resins, the heat-resistance if bad quality quartz surface will reduce down. You can use the lighter to burn the sample, and see whether there is the trace.

5. Weight Comparison

High quality quartz stone of higher density will be heavier. So getting two quartz stone in one size to make a comparison would help you a lot.
