What is usually printed on the ceramic tile box?

Grade marks are generally printed on the outer boxes of ceramic tiles.

Generally speaking, there will be grade marks on ceramic tile packaging boxes, which are divided into superior products and first-class products according to grades. If the package says superior products, it means that the quality of tiles is better; In addition, the grades of ceramic tiles can be divided into three grades according to different radioactivity: A, B and C. If the package says Class A, the quality is better.

How to choose tiles:

1, look at the appearance.

The color must be uniform, and its surface should be smooth, the pattern should be complete, there can be no color difference and deformation, but also depends on the density of the embryo bottom.

2. Listen to the sound.

You can tap gently with a hard object. If it sounds crisp, it means that the product has good porcelain and good quality.

3. weigh yourself.

There is another way to judge the density of tiles by weighing components. If the volume is the same, the heavier the tile, the better the quality.

4. Drop test.

Another method is to drip water on the back of the tile. At this point, you can observe whether the water disperses quickly or slowly. Under normal circumstances, the slower the water absorption, the greater the density of tiles. On the contrary, the faster the water absorption rate, the greater the density. The former is of better quality.
