What is artificial stone? Artificial stone is a mineral filled polymer composite material formed by vacuum casting or compression molding of natural mineral powder, high-performance resin, and natural pigments. It can be divided into artificial calcium powder board, aluminum powder board, acrylic, composite acrylic, artificial granite and quartz stone, among which the hardness and appearance of artificial granite and quartz stone are comparable to natural stone. Today we will mainly learn about the differences and identification methods between artificial granite and quartz stone!
artificial marble
Gangshi, also known as synthetic stone, reconstituted stone, or engineered stone. It mainly uses natural marble fragments and stone powder as raw materials, and can also add mosaic, shell, glass and other materials as embellishments. It uses organic resin as a binder, and is made into square materials through vacuum stirring and high-pressure oscillation. Then, it is cured at room temperature (curing time is more than 7 days), sawed, polished, and other processes to make boards.
quartz stone
Quartz stone is synthesized from over 90% quartz sand and 10% resin. It is named quartz stone because the raw material contains up to 93% quartz sand. Both are made into boards through processes such as vacuum, high pressure, kiln heating and solidification, sawing, polishing, and polishing.
Compared to quartz, granite has lower hardness and insufficient wear resistance. But the texture is delicate, the price is cheap, and it can be used for some complex shapes.
About the identification method of granite and quartz
Some people say to use a knife to cut the board, while others say to use acid foam All of these are correct, but is there a simple way for people who don’t understand stones or chemistry to easily distinguish authenticity?
have Just look at the back!
The back of the real quartz stone is polished by a turntable and has obvious circular scratches.
The back of the granite is relatively flat. It is cut horizontally, with faint straight marks or no scratches.
So, if there are curved scratches on the back, it is a real quartz plate, and if there are straight scratches or no scratches on the back, it is a granite.
