1. First of all, pay attention to whether the lid is suitable. We know that the ceramic cup lid can prevent the water from cooling down so quickly. If the lid is not properly covered, it may be a defective product, which will also affect future use.
2. Listen to the sound and lightly flick your fingers. If there is a clear and pleasant sound, then the porcelain body is fine and dense. If the sound is hoarse, then it is inferior porcelain and should not be bought.
3. When drinking water, the mouth will touch the wall of the cup, so there should be no patterns on the top of the outside of the cup wall, that is, where the mouth touches, and it is best not to have patterns on the inner wall. Because these glaze decorations contain traces of heavy metals such as lead and cadmium, they are not easy to use for a long time. It is harmful to the human body.
4. Touch the surface. Check whether it is smooth, check whether there are cracks, small holes, black spots, if it is as smooth as glass, the product is better.
