看以整箱瓷砖中抽出几块,看它的白度、裂纹,缺釉。看整块瓷砖的正面和边缘是否涂满釉层。几块瓷砖平放在一起看色差是否明显。侧看瓷砖表面是否有斑点和疵点。按将瓷砖面朝下平放在玻璃上,按瓷砖四角,测定瓷砖平整度,越平整的质量越好。 Look for a few pieces of the whole box of tiles to see its whiteness, cracks, lack of glaze. See if the front and edges of the entire tile are covered with glaze. A few tiles are put together to see if the color difference is obvious. Look at the tile surface for spots and defects. Press the tile face down on the glass and press the four corners of the tile to determine the flatness of the tile. The flatter the better the quality.
