Nowadays, quartz stone is widely used in cabinet countertops. As a "face project", the choice of quartz stone has also become a problem.
Why do some people's countertops are durable and do not change color, and their homes have constant cracks and penetration problems? Today we will talk about the identification and selection method of quartz stone.
1. Look at the price.
The price of a good quartz stone is generally above 800 yuan, and the cheapest one is also around 350. But not the ones above 800 are all good quartz stones, so you need to shop around, and merchants who fight price wars may use inferior granite as quartz stones.
2. Identify with white vinegar or oxalic acid.
High-quality quartz stone should contain more than 93% quartz crystals, and will not chemically react with acidic substances. Poor-quality quartz stone contains more calcium substances, which will react with acid to produce bubbles.
3. Use a hard object to observe the scratches.
The main component of quartz stone is made of quartz sand, which is silicon dioxide. In nature, the hardness is equivalent to diamond. A good quality quartz stone will only show minor scratches after being scratched with a key or a knife. Obviously, the inferior quartz stone countertops contain inferior materials such as calcium powder. If they are scratched with a key, there will be white powder and obvious scratches.
4. Pour soy sauce or red wine to test the permeability.
Soy sauce is the best test material. Pour it on the surface of the stone. After a few hours of observation, a good quartz stone has a very high density, and colored objects are not easy to penetrate, and leave no traces after being wiped off. Inferior quartz stone is easy to penetrate and is difficult to recover.
5. Bake with fire.
Quartz stone has high temperature resistance properties. After burning it with a lighter for a while, it is generally high-quality quartz stone that can be cleaned with water. On the contrary, it is inferior quartz stone.
6. Observe the particle distribution with naked eyes to judge the density.
The quartz stone of better quality and heavier weight is produced under the conditions of high temperature and high pressure by a press, with relatively uniform particles, high density and not easy to penetrate;
The inferior quartz stone is produced by a heavy-duty press for casting and production. It has a high density, has pores, and is easy to penetrate, and there will be small particles on the front side and large particles on the back side.
Generally speaking, the heavier quartz stone under the same area is of better quality, and the thickness is generally 1.5cm, and the budgeted 2cm is better. The cabinet liner is good for chopping meat without pressure.
