How To Distinguish True And False Quartz Stone
Jun 18, 2021
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 that it has strong stain resistance. If it can’t be wiped off it means that it has poor stain resistance. It is recommended not to buy it. In addition, the quartz stones produced by regular manufacturers have ink-jet codes on the back, and pay attention to the signs.
The specific method:
1. 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 resistant to scratches and abrasion.
2. The steel knife slashed through, leaving a white mark on the fake quartz stone. Because the plate is not as hard as steel, 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, one black and one white, the true and the false appear.3. 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 influence on it, that is, it will not deform and break; because of the large amount of resin, the quartz stone contains a large amount of resin. Therefore, it is particularly prone to deformation and scorching at high temperatures.
4. Press the lit cigarette butt on the countertop, or burn it directly with a lighter. If there is no trace, it is the real product, and the one with the burnt black trace is the fake.
