There are good and bad ceramic tiles. Each brand of ceramic tiles basically has several different grades of ceramic tiles. In order to help you identify and evaluate the quality of ceramic tiles, it is recommended that you refer to a few principles. :

1. When choosing ceramic tiles, you must inquire clearly about the grade of ceramic tiles (Grade AA), Grade One (Grade A), Qualified Grade) and try to choose premium products here.

2. Pay attention to the appearance of ceramic tiles. Good ceramic tiles should have no defects such as bumps, bulges, and warped corners. They should have straight edges and flat surfaces, and no cracks, damage, defects, or impurities attached to the surface.

3. Look at the glaze of the ceramic tiles. The surface should be uniform, flat, smooth, bright and consistent in color. (If the ceramic tile surface has particles, is not smooth, has different shades of color, is uneven in thickness, or even has uneven concavities and convexities, it is a bad product)

4. Look at the copywriting. Good ceramic tiles have clear patterns and colors, and no unevenness. Obvious color leakage, misalignment, disconnection or different shades.

5. Look at the hardness. Ceramic tiles have good hardness, strong toughness, not easily broken, and good density.

6. To absorb water, you can drop water on the surface of the ceramic tile to see how quickly it spreads and infiltrates. The slower it absorbs water, the density of the ceramic tile is high. On the contrary, the faster it absorbs water, the density is sparse, and its intrinsic quality The former is better.

7. Listen to the sound and lower it with your fingers. If the sound is clear and pleasant, it is a high-quality sound. If the sound is dull, it is a low-quality sound.

With the above standards, no matter what kind of tiles you are facing, we can help you identify them.

I hope the above answers can solve your questions in time.
