Many people are overwhelmed by the variety of ceramic tiles and don't know how to choose. In fact, it is enough to look at the "surface" of the ceramic tiles when buying ceramic tiles. Good ceramic tiles have no defects such as bumps, bulges, and warped corners. The edges are straight and flat, the error of the side length does not exceed 2mm to 3mm, and the error of thickness does not exceed 1mm.
　　Choosing high-quality ceramic tiles is not only easy to install, but also has a good effect of laying, flat and beautiful, and can save labor time and auxiliary materials, and is durable.

　　Flatness: refers to the horizontal degree of the tile surface. The flatter the surface, the better the paving effect. As long as the tiles are laid correctly, there will be no bulging or concavity. Tiles with good flatness have no bending or warping on the surface, are easy to install, and the ground is flat after installation.

　　Color difference: Lay the tiles flat on the ground, forming a square meter, and watch them from a distance of three meters to see if there are any different shades of color or if they cannot be connected, and if there is any aesthetic obstacle. If not, it means there is no color difference. Tiles without color difference are laid at home to give people a beautiful enjoyment, while tiles with color difference make people irritated and uncomfortable to the eyes.

　　Glaze: The glaze surface should be uniform, smooth, neat, bright, delicate, bright, and of uniform color. Glossy glaze should be crystal clear and shiny, and matte glaze should be soft and comfortable. If the surface has particles, is not smooth, has different shades, is uneven in thickness, or even bumpy and cloud-like, it is inferior.

　　Hardness: Tiles with good hardness, strong toughness and not easy to break are top-quality tiles. Carefully observe whether the broken pieces are dense or loose, whether the color is consistent, and whether there are particles. Check the edges and corners of the broken pieces to see if they are hard and brittle, or soft, and whether they leave scratches or scattered powder. If the former is the case, the tile is top-quality, and the latter is low-quality.
