1. Is the ceramic cup poisonous?
1. The so-called poison of ceramics mainly refers to the dissolution of lead and cadmium. In general, in order to make the surface of the ceramic cup look good, usually the surface is decorated with a color pattern, and lead cadmium is mainly introduced by these colors. The ceramic cups of regular manufacturers are strictly tested. The lead and cadmium dissolution is in line with national mandatory standards, so it is safe and reliable.
2. The ceramic cup is harmful. It does not mean that the cup is highly toxic and cannot be used. It means that the lead chrome dissolved in the cup will cause damage to the human machine during use. Lead chrome is one of the heavy metal elements. If such elements enter the body with daily drinking water, it will cause great harm to the body. Because such heavy metal elements can not be excluded by the human body, they will accumulate in the body and damage the normal function of the human body.
Second, the choice of ceramic cups

2. When you drink water, the mouth will touch the wall of the cup, so the top of the outside of the cup wall, that is, the place where the mouth touches, must not have a pattern, and the inner wall is best not to have a pattern. Because these glaze decorations contain trace amounts 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.
3. Is the cup wall smooth, inside the cup, smooth, not grind. Can be touched by hand, look smooth, or very uneven. The cup is designed to try to drink water by hand to see if the cup can hold steady. The cup handle is also a very important part. You should be able to use the force and not slip.
