So what problems should we pay attention to when using and purchasing ceramic tableware?
Although ceramic tableware is beautiful and easy to use, there are still some matters worthy of our attention when using ceramic tableware. Let's introduce the precautions for the use and purchase of ceramic tableware.
1. Do not use ceramic tableware to store acidic foods and drinks such as juice, wine and coffee for a long time. Because the longer the ceramic tableware holds acidic food or drink and the higher the temperature, the easier it is to dissolve lead, which is equivalent to aggravating the toxic and side effects of lead dissolution.
2. Don't choose glazed decoration when choosing ceramic tableware, especially don't paint the inner wall of ceramic tableware. You can choose underglaze or underglaze decoration. For example, blue and white is a kind of ceramics that people like to decorate with underglaze colors.
3. Buy back ceramic tableware, soak it in vinegar-containing water first and then boil it, which can remove most toxic substances and greatly reduce the potential harm of ceramic tableware to human body.
4. Although the painted color of the inner wall of ceramic tableware is bright, the colored glaze contains heavy metal elements such as lead, mercury and cadmium. Among them, cadmium and lead are easy to cause liver or other visceral poisoning, and mercury can cause liver and kidney sclerosis. The more glazed ceramics are, the brighter the colors are, and the more compounds such as lead and cadmium are. Don't pay too much attention to patterns when choosing ceramic tableware, especially don't use tableware with painted inner walls. The newly bought tableware can be soaked in vinegar for 2~3 hours to dissolve the harmful substances in the glaze. In addition, painted porcelain should never be heated in the microwave oven.
5. Under-glaze porcelain is the safest, with more blue-green patterns and less red and yellow. First draw underglaze color, then glaze, and then directly fire at high temperature. Because there is no need for low melting point substances, there is no need to add lead to the pigment, which is not easy to precipitate and is the safest; The color in glaze is glazed first, then painted, and then fired at high temperature. Lead-free, pigment is not easy to precipitate, and it is relatively safe. The place where the underglaze color has patterns feels as smooth and shiny as other places, while the underglaze color is somewhere in between. Although the gloss is good, the feel is not smooth.
