How to Distinguish Good Quartz Stone From the Bad

Posted by RachelHJM on April 22nd, 2017

Method 1:

Evaluating the quality of quartz stone, it is important to recognize that degree of surface finish. To some extent, degree of finish represents the fouling resistance. The simplest method is to use a marker paint on the quartz stone, whether can erase it easily or not represents the fouling resistance. Difficult to wipe out means that the fouling resistance is poor, suggest not to buy.

Method 2:

Hardness is also a method to distinguish the good from the bad. Hardness stands for wear resistance. Use the steel knife cut the surface of quartz stone instead of key. Quartz stone is made of 94% quartz and 6% resin, hardness of 7 degrees, and are derived by the marble powder and resin synthesis, so the hardness commonly reaches 4 to 6 degrees. In other words, quartz stone is harder than Agglomerated stone. After cut surface with steel knife, revealing the white, while pure quartz would leave only a black printing. Because steel knife not stroke fixed quartz, instead of leaving traces of steel. It is quiet easy to recognize the truth and false.

Method 3:

Quartz material due to its own characteristics, determines its characteristics of high temperature resistant, below 300 degree Celsius temperature will not have any impact to its. Thus it will never have deformation and fracture; Due to contain large amounts of resin, are derived under the condition of high temperature especially prone to deformation and the phenomenon of burning performance.

Stub out cigarette butts on the surface, or directly use lighter to burn, no traces are genuine, have charred traces are fakes.

Method 4:

High quality quartz countertops usually add 100% high quality full aluminium powder, a small spoon edible vinegar can let all of the inferior man-made stone, quartz, show true colors. But other types of vinegar are invalid, such as mature vinegar is invalid.

With a tablespoon of vinegar in artificial stone and quartz, 30 seconds later, if there is a lot of tiny bubbles that are false quartz. For false quartz, the calcium carbonate can react with white vinegar, produce bubbles. Such countertops are low price, easy to aging, cracking, color absorption, as well as short service life.
