Smooth and beautiful appearance
Good tiles have no defects such as bumps, bulges and corners, but they should be straight. Buying high-quality tiles is not only convenient for construction, but also flat and beautiful, with high quality, saving working hours and auxiliary materials, and durable.
This pattern is clear and consistent.
Good tile patterns, patterns and colors are clear and consistent, exquisite in workmanship and comfortable in appearance, without obvious color leakage, dislocation, broken line or different shades.
The glaze is even and smooth.
If the glaze of ceramic tile is uniform, smooth, bright and consistent in color; If there are particles on the surface of ceramic tile, it is not smooth, the color is different, the thickness is uneven or even uneven, and it is a cloud-like product.
The voice is crisp and pleasant.
Hold a corner of the tile with your left thumb, forefinger and middle finger and hang it down easily. Click the middle and lower part of the tile with your right index finger. If the voice is crisp and pleasant, it is the top grade. If the sound is dull and stagnant, it is the bottom level.
Good hardness, neither brittle nor rotten.
Ceramic tiles are high-grade, with good hardness, strong toughness and not fragile. You can carefully observe whether the broken fragments are fine or loose during transportation and whether the colors are consistent.
The slower the water absorption, the greater the density.
You can drop water on the back of the tile and see how quickly it soaks after the water is dispersed. Generally speaking, the slower the water absorption, the greater the density of tiles; On the contrary, the faster the water absorption, the thinner the density of ceramic tiles, and its internal quality is better than the former.
