300 pieces of tiles, the color is more uniform and consistent, without too much color difference or no color difference. A few bricks may not be very obvious. Once a large area is paved, under the illumination of light, you will see obvious differences, and the thickness of the glazed cross-section of the tiles is thicker and the quality is better.

Its glazed surface is smoother and flatter, with a regular periphery, and there will be no roughness such as barbs, missing corners, and missing edges. When you choose, you can put more than four bricks together, and it is easy to find that there is a big difference between the gap and the flatness. 300 pieces of tiles, the pattern is more complete and textured, the porcelain is more transparent, without black spots and obvious impurities.
300 and 30 tiles a piece, you can pick up the tiles and try the tiles by hand. You can find that 300 pieces of tiles are of good quality, high density, heavy hand feeling and great weight. If you feel that the quality is not too bad, you can also drop water or tea on the tiles to see how fast the water seeps into the tiles. The slower the water absorption, the higher the density of the tiles and the better the quality, which can effectively prevent liquid from seeping into the tiles.
There is also the obvious feeling of good and inferior tiles when they are processed and cut. 30 ceramic tile is very brittle, everything can be cut, 300 ceramic tile is more difficult to cut, very strong and firm.
