Judging method one: look
It is very important to judge the quality of quartz stone is the finish, because the finish represents the stain resistance. The easiest way is to use a marker to draw on the quartz stone and see if it can be wiped off. If it can be wiped off, it means the stain resistance is strong. If it cannot be wiped off, it means the stain resistance is poor. It is recommended not to buy it.

In addition, the quartz stones produced by regular manufacturers have ink-jet codes on the back, pay attention to the signs.
Judgment Method two: Plan
Hardness is the identification of wear resistance. The simple method is to use a steel knife to draw, and the key cannot be used for identification. Quartz stone is made of 94% quartz and 6% resin, with a hardness of 7 degrees, while granite is synthesized from marble powder and resin, so the hardness is generally 4-6 degrees. Simply put, the ratio of quartz stone The granite is hard, more scratch-resistant, and wear-resistant.

The steel knife slashed through, leaving a white mark on the fake quartz stone, because the plate is not as hard as steel, and the surface is cut by the steel knife, revealing the white inside. While the pure quartz stone is scratched by a steel knife, it will only leave a black mark, which is caused by the steel knife not being able to scratch the quartz stone but leaving traces of steel.
Judgment method three: burn
Due to the characteristics of its own material, quartz stone determines its high-temperature resistance. The temperature below 300 degrees Celsius will not have any effect on it, that is, it will not deform and break; because it contains a large amount of resin, it is particularly prone to deformation and scorching at high temperatures.
Press the lit cigarette butt on the countertop or burn it directly with a lighter. If there is no trace, it is the genuine one, and the one with the burnt black mark is the fake.
Judgment method four: acid
High-quality quartz stone countertops generally add 100% high-quality aluminum powder, and a small spoonful of white vinegar can make all inferior artificial stones and quartz stones show their original shape. But other types of vinegar are invalid, such as aged vinegar.
China rococo quartz
Pour a tablespoon of white vinegar on the artificial stone and quartz-stone countertops. After 30 seconds, if there are many tiny bubbles, it means it is a fake quartz stone. Because the calcium carbonate in the fake quartz stone chemically reacts with the white vinegar to produce bubbles. Such countertops are low in price, easy to age, crack, absorb color, and have a short service life.
