1, after reading it. The washbasin with good finish has bright color, good dirt resistance and good self-cleaning. You can see whether there are small sand holes and pits on its surface under strong light. If there are fewer sand holes and pits, the finish will be better. You can also touch the west with it to see if its surface is smooth and delicate enough.

2, look at the water absorption rate. Water absorption is one of the testing methods for all ceramic products. Usually, the lower the water absorption, the better the products will sell. If the water absorption is high, the ceramics will expand and crack. We should choose a ceramic washbasin with low water absorption of 3% and relatively good quality.
