The purchase of the tiles: any one to take out, to see whether the surface is smooth, intact, glaze should be uniform, bright, no spots, lack of glaze, bump phenomenon, around the edge of the regular. Glazing is not bright, astringent, or air bubbles are quality problems. Then take out a piece of brick and align two pieces. The smaller the middle gap, the better. If it is a pattern tile, four pieces must be used to piece together a complete pattern, and whether the pattern of the brick should be connected and clear should be considered. Then take out a box of bricks and place them on a large flat surface. Look at the effect from a little distance away. Whether it is white or other colors or patterns, the color should be the same. If there are individual bricks, shallow points, it will be difficult to see. The effect of the entire decoration, put these bricks up and down together, whether the size of the brick is the same, the deviation of the small brick allowed to plus or minus 1 mm, the large brick allowed to be plus or minus 2 mm. Take a piece of brick to knock another piece, or use other hard objects to knock on the brick. If the sound of the brick is crisp and loud, it indicates that the quality of the brick is good and cooked; if the sound is abnormal, there is heavy skin or crack phenomenon in the brick: When the heavy skin is formed by the brick, the air in the material is not discharged, resulting in poor bonding between the material and the material, internal cracking, and invisible from the surface. Only listening to sound can be identified.

Note: There is also to pour water on the back of the tile to see if it is infiltrated by the net. It is best to see if the water seepage time is even. If there is no water seepage, there is no way to do this. This is mainly a wall tile.
