1. Observe the glazed surface of the ceramic tile. The glaze should be smooth and delicate, and touch it without any particles. The smooth tile should be crystal clear and glossy, and the matt brick should be soft. The color pattern should be exquisite, realistic, without obvious defects such as lack of color, broken lines, and misalignment. Put a few pieces of glazed tiles together and look closely under the light. The color difference of a good product is very small, and the hue of the products is basically the same; while the poor product has a large color difference, and the shades of the products are different.
2, from the same type of glazed tiles randomly selected two, together to see if the joint, the description of the joints glazed tile flatness is good. When it's time, we must rotate the glazed tiles so that all sides of the glazed tiles are aligned. It is best to find a flat tabletop, put the two glazed tiles together completely, and then touch the corners of the two glazed tiles that are close together, flat tiles, and the edges of the two glazed tiles. The corner should also be on the same horizontal line.
3, enamel glazed tiles feel the density, feel heavy (high density) is good.
4. Pour some water behind the glazed tiles to see how quickly the water is absorbed by the tiles. The slower the speed, the better the quality of the tiles and the higher the water absorption rate of the bricks. Some bricks pour water from the back, and in turn they can see the water stains from the front. This kind of glazed tile is absolutely unnecessary. It should be noted that the test of water must be to pour the water on the back of the glazed tile. Many businesses see that you try to put water on the front of the glazed tile. If you do not see water, it is a good brick. If the glazed tile is water-absorbing on the front, it would be rather inferior.
Some glazed tiles are so strong that they can hardly fall on the ground and they will not break. Of course, such bricks are also very good.
