Purchase of ceramic cups
1. First of all, pay attention to whether the lid is suitable. We know that the ceramic cup lid can make the water not cool 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 flick your fingers. If it makes a crisp and pleasant sound, then the porcelain body is fine and dense. If the sound is hoarse, it is inferior porcelain and cannot be bought.
3. When drinking water, the mouth will touch the wall of the cup, so the top of the outer side of the cup wall, that is, the place where the mouth touches, should not have a pattern, and it is best not to have a pattern on the inner wall. Because these glaze decorations contain trace amounts of lead, cadmium and other heavy metals, they are not easy to use for a long time. Harmful to human body.
4. Touch the surface. Check whether it is smooth, whether there are cracks, small holes, black spots, if it is as smooth as glass, the product is better.
