一、对角比尺寸
I. Diagonal Ratio Dimensions
把两块同一品种的砖面对面重叠在一起，四角对齐，转动其中的一片，四边尺寸始终一致者好。此法尤其适用于表面光滑的瓷砖检测。
It is better to overlap two bricks of the same variety face to face, align them at four corners and rotate one of them. The sizes of the four sides are always the same. This method is especially suitable for the detection of tile with smooth surface.

二、查看平整度
2. Check smoothness
把两块同一品种的砖面对面重叠在一起，四角对齐，转动其中的一片，转动容易者质量差，反之则好。此法不能用于检测仿古砖。仿古砖的显著特点是表面色彩和花纹的任意变化，表面可以凹凸不平。
When two bricks of the same variety are overlapped face to face, aligned at four corners, and one of them is rotated, the quality of the easy-to-rotate bricks is poor, and vice versa. This method can not be used to detect antique bricks. The remarkable feature of antique brick is the arbitrary change of surface color and pattern, and the surface can be uneven.
三、看吸水率
3. Seeing Water Absorption Rate
吸水率的大小是瓷砖质量的一个重要标志。将一小杯水倒在砖体的背面，水消失得越快说明吸水率越高，质地越疏松，强度越弱，反之则反。
Water absorption is an important sign of tile quality. Pour a small glass of water on the back of the brick and the faster the water disappears, the higher the water absorption, the looser the texture, the weaker the strength, and vice versa.

四、看光洁度
IV. Looking at Smoothness
这是检测抛光砖品质的一个重要指标。将抛光砖表面的保护蜡用软布或试剂清洗干净，放在灯光或阳光下，成45度的斜角查看，表面越亮越好。
This is an important index to test the quality of polished bricks. Clean the protective wax on the polished tile surface with soft cloth or reagent, put it in the light or sunlight, and look at it at an angle of 45 degrees. The brighter the surface, the better.

五、听声音。
5. Listen to the voice.
用硬物轻击，声音越清脆，则瓷化程度越高，质量越好。也可以左手拇指、食指和中指夹瓷砖一角，轻松垂下，用右手食指轻击瓷砖中下部，如声音清亮、悦耳为上品，如声音沉闷、滞浊为下品。
The more crisp the sound is, the higher the degree of ceramization and the better the quality are. It can also be left thumb, index finger and middle finger clip a corner of the tile, easily hang down, with the right index finger lightly hit the middle and lower parts of the tile, such as clear sound, pleasant for the top grade, such as voice dull, muddy for the second grade.
