There are labels on American ceramic tiles.

Watermark anti-counterfeiting of ceramic tiles is a patented technology of American ceramic tiles. This anti-counterfeiting technology is used on some polished tiles of Meitao, and the trademark LOGO of Meitao tiles can be seen by using purple light to illuminate the tile surface.

Three methods to identify the authenticity of American ceramic tiles:

1. The glazed surface of genuine American ceramic tiles looks very glossy, and the feel is very delicate and smooth, and obvious cracks and other defects can not be seen under fluorescent lamp. There is no obvious dislocation or lack of color in the genuine American ceramic tiles with patterns, and the trademark and shading on the back of the tiles are very clear.

2. The size deviation of genuine American ceramic tiles is very small. You can put the unpaved tiles in the same batch vertically on the ground to see if there is any unevenness, and at the same time, close the edges of two American ceramic tiles to see if there is any gap. The surface of good American ceramic tiles is beautiful and flat after paving, while the surface color of inferior American ceramic tiles is different, and the effect after paving is not very good.

3. Tap gently on the forehead surface of American ceramic tiles, and the sound of genuine ceramic tiles is very crisp, while the inferior American ceramic tiles are fired at too low temperature or too short time. It will make a hollow sound when you knock. At the same time, you can pick up the tiles and weigh them. American ceramic tiles with the same specifications are heavier, which means that the water absorption is low and the quality is better.
