Four methods for distinguishing between true and false quartz stones

- Dec 24, 2018 -

Judgment method one: look

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.

Judgment method 2:

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.

Judgment method three: burning

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.

Judgment method four: 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.

Steps to identify true and false quartz stones:

Many people don't know much about quartz stone. I don't know where to start when I buy it. Here are a few experiments to let everyone know how to distinguish true and false quartz stone countertops.

Look at the eyes

The back of the regular quartz stone will have the code of the stone company.

There should also be lines on the back, because the hardness of the quartz stone is very hard, so there should be a cut pattern.

2. Soak with strong acid

Inferior quartz stone will be surrounded by strong acid and bubbles will appear around it.

This is a high-quality quartz stone that will not bubble when soaked with strong acid.

3. Scrape with a knife

Many people don't know much about quartz stone. I don't know where to start when I buy it. Here are a few experiments to let everyone know how to distinguish true and false quartz stone countertops.

After the inferior quartz stone is scraped with a knife, powder will appear.

The high-quality quartz stone is hard, there is no powder after scraping, and the metal color of the knife remains on the quartz stone.

4. Burn with fire

Add some detergent and water before scrubbing.

Inferior quartz stone, there will be yellow marks that can not be wiped off after burning.
