selection of ceramic tiles: take out one piece at random to see whether the surface is flat and intact. The glaze should be uniform, bright, free of spots, lack of glaze, bumps, and the surrounding edges should be neat. The glaze is not bright, astringent, or has bubbles, which are all quality problems. Take out another piece of brick, align the two pieces, and the smaller the gap in the middle, the better. If it is a pattern brick, you must use four pieces to piece up a complete pattern, and you should also pay attention to whether the pattern of the brick is connected and clear. Then take out all the bricks in a box and lay them flat on a large plane. When looking at the whole effect from a distance, whether white, other colors or patterns, the color should be consistent. If there are individual bricks with deep and light spots, it will be difficult to see and affect the whole decorative effect. Put these bricks up one by one, and compare whether the size of the bricks is consistent. The deviation of small bricks is allowed to be plus or minus 1mm, and that of large bricks is allowed to be plus or minus 2mm. Take one brick and knock it on another, or knock it with other hard objects. If the sound of the brick is clear and loud, it means that the brick is of good quality and cooked; If the sound is abnormal, it indicates that there is a double skin or crack in the brick: the double skin is that when the brick is formed, the air in the material is not discharged, resulting in poor bonding between materials and internal cracks, which can not be seen from the surface, and can only be identified by listening to the sound

note: also, pour some water on the back of the ceramic tile to see if it is infiltrated in the net. It is best to have an even water seepage time. If there is no water seepage, there is no way to get this brick. This is mainly wall bricks
