Are there any taboos when buying ceramic tableware? Qi Zhiyuan Ceramics tells us below.
1. Try not to buy dark and colorful ceramic tableware. If the production process of such ceramic tableware does not meet the standards, the glaze attached to the surface of the ceramic tableware will release toxic elements such as lead and cadmium that are harmful to the human body.
2. Do not buy ceramic tableware with uneven inner walls or patterns. Ceramic tableware with a non-smooth inner wall is likely to cause product failure due to uneven temperature during the firing process; and if the tableware with a pattern on the inner wall is a glaze ceramic, the lead compounds in the glaze can be dissolved by acid. When food comes in contact with the dishes, lead may be dissolved by organic acids in the food.
3. Do not use ceramic tableware with scratches. Many people think that it is very common for tableware to have scratches. As long as it does not affect the use, it is not necessary to throw it away. In fact, this idea is very wrong. Once scratches occur on ceramic tableware, it is likely to expose the glaze in the porcelain plate. Scratched tableware used to hold foods such as acid and high temperature, it is likely to precipitate heavy metals and other harmful substances, which endangers human health. And if the tableware used is inferior and unqualified ceramic products, the harmful substances will be precipitated, and enter the human body with food for a long time, it is likely to cause chronic poisoning.
4. Do not use ceramic cloth or decontamination powder to clean ceramic tableware. Some people may think that cleaning ceramic tableware with a piece of cleaning cloth and decontamination powder will be cleaner, but at the same time, it may also damage the glazed surface of the tableware, thereby releasing harmful substances that affect our human health.
The above is the main content of Qi Zhiyuan Ceramics which introduces the taboos when purchasing ceramic tableware.
