1. Chooses quartz stone countertop with a marker pen.
The important thing about the quartz stone in the cabinet is the finish, because the finish represents whether it will absorb color. The color absorption of quartz is a very troublesome problem, even a little oil will not be wiped off. You can use a marker pen to draw on the quartz stone, and it won’t absorb color if you can wipe it off.
2. Identify the hardness of quartz stone with a steel knife.
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. When a pure quartz stone is scratched by a steel knife, only a black mark will be left, because a steel knife cannot scratch the quartz stone, but will leave traces of steel.
3. High temperature test.
Quartz stone is high temperature resistance due to its own material characteristics, and will not deform and break at temperatures below 300 degrees Celsius.
4. Pour a spoon of white vinegar on the quartz stone countertop. After 30 seconds, if there are many tiny bubbles, it is fake quartz stone. Such countertops are low in price, easy to age, crack, absorb color, and have a short service life!
