Anti-counterfeiting of ceramic tile watermark is a patented technology of American ceramic tile. This anti-counterfeiting technology is used in some polished tiles in Mei Tao, and the trademark logo of Mei Tao tiles can be seen by irradiating the surface of the tiles with violet light.
Three methods to identify the authenticity of American ceramic tiles;
1. The glazed surface of genuine American tiles looks very shiny, feels very delicate and smooth, and there are no obvious cracks and other defects under fluorescent lights. Authentic American tiles with patterns have no obvious dislocation or lack of color, and the trademarks and shading on the back of the tiles are very clear.
2. The size deviation of genuine American tiles is very small. You can put the same batch of unpaved tiles on the ground vertically to see if there are any irregularities, and at the same time close the edges of two American tiles to see if there are any gaps. The surface of good American tiles is beautiful and flat after paving, but the surface color of inferior American tiles is different, and the effect is not very good after paving.
3. Tapping gently on the surface of American ceramic tiles makes the sound of genuine ceramic exhibition clear, while the firing temperature of inferior American ceramic tiles is too low or the time is too short. When you knock on the door, it will make a hollow sound. At the same time, you can pick up the tiles and weigh them. American tiles of the same specification are heavier, indicating that the water absorption rate is low and the quality is better.
