how to distinguish the quality of quartz stone

The quartz stone market in China has been maturing for over a decade, and there are more and more quartz stone manufacturers. The prices and quality of products vary greatly. How to distinguish the quality of quartz stone is a problem that every consumer needs to face. HereKJL can give some personal experiences:

1. Look at the surface. Good quartz stone has good surface brightness, uniform grain and pattern, less impurities, and a cold and hard feel when touched.
2. Look at the cut surface. The genuine pressed quartz has consistent grains throughout, and there will be no layering of grains or no grains on the back.
3. Test hardness. Good quartz stone has high hardness, and ordinary iron tools cannot scratch it. You can use a knife blade or key to scratch the surface hard. A normal one will leave a black mark that can be wiped off by hand, and no trace will be left. You can also drop two samples together and let them slide down quickly. Good quartz stone will produce sparks when it slides down.
4. Listen to the sound: Good quartz stone is made from high-purity quartz sand, which results in a dense board. When tapped, it produces a clear and crisp sound.
5. Look for the label: Regular manufacturers will have their own trademarks and anti-counterfeiting labels on their products.
