the toxicity of ceramic cups mainly refers to the dissolution of lead and cadmium, which is not brought by ceramic cups, but introduced by merchants after decorating the surface and wall of the cups with colorful patterns for the sake of looking good. The ceramic cups that broke out in recent years are poisonous, mostly on glaze or painting materials. Glaze forms glaze after high temperature, and the proportion of chemical added is too high, thus causing toxicity. Paint is a low-cost chemical pigment, which contains heavy metals such as lead and mercury, which provides its danger.
The firing temperature of a ceramic cup also determines whether it contains toxicity. If the cup is fired at high temperature, harmful substances will easily disappear and transform, and it is not easy to produce toxicity. The safety of cups fired at medium and low temperatures is greatly reduced.
More than a dozen ceramic cups may be toxic. Most of these cups are fired at medium and low temperatures, and the pigments used may also be infiltrated with heavy metal components such as lead and mercury, or they may be leftover goods used by manufacturers when they make large goods, which do not meet the national standards and cannot guarantee safety. Therefore, it is recommended that you choose formal channels when purchasing, and you should read the materials in the ingredient list clearly.
Is the ceramic coating of the thermos cup toxic? Can the ceramic cup hold boiling water?
Some thermos cups are not coated with stainless steel, but with ceramic coating. Is the ceramic coating of the thermos cup toxic? Ceramic cups are often used in life. Many people buy ceramic cups and think it is safer to drink water with ceramic cups. Then, can ceramic cups hold boiled water?
The ceramic coating of the thermos cup is painted with silicone paint or Teflon, which is not a real ceramic. They are used after national testing, so they are not toxic. However, they are related to the coating, which may fall off after being used for a long time. Once the fallen coating is drunk with water, it is very easy to cause harm to human health. Therefore, the ceramic coating of the thermos cup has certain security risks.
Ceramic cups can be filled with boiling water. High temperature resistance is the main feature of ceramic cups. High temperature will not release toxic and harmful substances from ceramic cups, so people can use them with confidence. Ceramic cups are mainly made of clay, ceramic soil and other clay, plus lime glaze and colorant, which are fired at high temperature through multiple processes. Ceramic cups that have been fired at high temperatures can naturally withstand high temperatures.
Ceramic cups can be divided into high-temperature cups, medium-temperature cups and low-temperature cups. Relatively speaking, high-temperature ceramic cups have a relatively high firing temperature, which can transform or disappear harmful pigment substances used on the surface of ceramic cups, and are not easy to produce toxicity, thus being safer. Therefore, when people buy ceramic cups, they should try to choose high-temperature ceramic cups.

Is it better to eat bowls made of ceramics or bone China?
With the improvement of people's living standards, many people have begun to have a higher pursuit of quality of life, and they will also have higher requirements in the choice of tableware. In recent years, bone China tableware has begun to enter everyone's field of vision and is widely sought after. So is bone China tableware really that good? Is the dining bowl made of ceramics or bone China?
In order to let everyone know better the advantages and disadvantages of ceramic and bone China rice bowls, I will make a comparison between ceramic tableware and bone China tableware:
1. Grade: bone China is known as the king of porcelain, which is a world-recognized high-grade porcelain. It was originally a British royal porcelain, and now the upper class in the United States and high-grade hotels in China also mainly use bone China tableware.
2. Aesthetics: The appearance of bone China tableware is very similar to that of ceramics, but on the whole, bone China is milky white, with softer, smoother and more transparent color.
3. Handle: Bone China is lighter and lighter than ceramics, and has a better handle, so it will be more convenient to use.
4. heat preservation: bone China has better heat preservation effect than ceramics, but it is easier to feel hot when using bone China to hold hot food.
5. Safety: Bone China is known as a true green porcelain. When it is made, its flower surface and glaze surface are fused into a whole, and it generally does not contain heavy metals such as lead and cadmium. However, if the quality of ceramic bowl glaze is not up to standard, heavy metals such as lead and cadmium may remain. However, we should also pay attention to the fact that some bone China techniques in the market are not up to standard, which may lead to lead and cadmium residues.
6. Price: As a high-grade porcelain, bone China is not only rare and precious in raw materials, but also very complicated in process, so the price of bone China will be much more expensive than that of ceramics.
The above is the main difference between ceramic rice bowls and bone China rice bowls. Generally speaking, bone China is better than ceramics, but as a tableware, the performance and safety of ceramics are still relatively high. If the family conditions are not particularly good, ceramic rice bowls are also a good choice.
