Ceramic tiles are inseparable from every family. When we choose them, we all attach great importance to their quality. There are many kinds of ceramic tiles, such as ceramic tiles and all-ceramic tiles. We don't know how to choose them. Last time we talked about the difference between full tile and ceramic tile.

Tapping the surface of ceramic tiles gently with your hands, the sound is dull ceramic tiles, the sound is cool all ceramic tiles, the main reason is that the firing temperature is different.
3. Appearance inspection
