How to judge the authenticity of quartz stone

An important point in judging the quality of quartz stone is the finish, because the finish represents stain resistance. The easiest way is to use a marker to draw on the quartz stone to see if it can be wiped off. If it can be wiped off, it means that the stain resistance is strong. If it can't be wiped off, it means that the stain resistance is poor. It is recommended not to buy it. In addition, the quartz stone produced by the regular manufacturer has a code on the back, pay attention to see the mark.

Draw

Hardness is also the identification of wear resistance. The simple method is to use a steel knife to draw, and the key can not be used to identify. Quartz stone is made of 94% quartz and 6% resin, the hardness reaches 7 degrees, and the granite is synthesized from marble powder and resin, so the hardness is generally 4-6 degrees, which is simply quartz stone ratio. Hard stone, more scratch-resistant, wear-resistant.

The steel knife is crossed, leaving the white quartz is a fake quartz stone, because the hardness of the plate is not as good as steel, and the surface is cut by a steel knife to reveal the white inside. The pure quartz stone is crossed by a steel knife, leaving only a black mark. The steel knife can't move the quartz stone, but it leaves the trace of steel. It is black and white, and it is true and false.

burn

Due to the characteristics of its own material, quartz stone determines its high temperature resistance. The temperature below 300 degrees Celsius will not affect it, that is, it will not deform and break. The granite contains a large amount of resin. It is particularly prone to deformation and charring at high temperatures. Press the cigarette butt on the table, or use a lighter to burn directly. The real thing is no trace, and the fake black mark is fake.

acid

High-quality quartz stone countertops will generally be filled with 100% high-quality aluminum powder. A small spoonful of edible white vinegar will make all the inferior artificial stone and quartz stone appear. However, other types of vinegar are ineffective, such as vinegar is not effective.

Use a spoonful of white vinegar to pour on the countertop of artificial stone and quartz stone. After 30 seconds, if many tiny bubbles are produced, it means fake quartz stone. Because the calcium carbonate in the pseudo quartz stone reacts with the white vinegar to generate bubbles. Such countertops are low in price, easy to age, crack, absorb color, and have a short service life.
