First, check whether the green color of the tiles is pure. This trick is very simple, mainly to observe whether the color on the back of the tile is uniform. The tiles with better quality have uniform and symmetrical body color.

Second, it is necessary to observe whether the particles in the cross section of the tile are fine or not. What consumers need to pay attention to is that the transverse plane mentioned here does not refer to the cutting plane around the tile, but refers to the fracture of the tile fragments. Generally speaking, the top grade is fine in texture, hard and crisp, and the color is consistent. Because the fine-grained tiles have strong waterproof ability; However, the tiles with larger particles are easily soaked by moisture, which affects the quality.

Third, pay attention to the thickness of glaze layer. The glazed surface of ceramic tile is what we call the whole surface of ceramic tile, and the thickness of glazed surface is the thickness of glazed cross section. Glaze is the most expensive material in ceramic tile cost. The thicker the glaze layer, the better the natural quality.

Fourth, listen. Tap on the tile and listen to the sound. If the sound is crisp and pleasant, it is top grade, if the sound is dull, it is inferior.

Fifth, we must test the water. Consumers can pour some water on the back of the tile, and pay attention to the speed at which the tile absorbs water. After a few minutes, see if the traces left by the accumulated water in front are obvious. The tiles slowly soaked after water dispersion have high density and inconspicuous water marks, which are regarded as top grade.

6. Take two bricks back to back and face to face to see if they can be in close contact. If the gap is too large, it can be judged whether there is warping.

Seven, find the ink on the surface and then scrub it for an hour to see if there are traces. If there is no trace, it is a good brick. If there is infiltration, resolutely do not choose.

Eight, take two bricks to measure the geometric size, length and width of two bricks, and look at the dimensional deviation of bricks sideways. No deviation is the best product.
