What problems should be paid attention to when choosing ceramic tableware?

Ceramic tableware has not only practical value, but also artistic value. So, below we will introduce how to buy ceramic tableware. 1. Do not use overglaze decoration when choosing ceramic tableware, especially the inner wall of ceramic tableware. It can be decorated with underglaze or midglaze. For example, blue and white is a kind of chinaware ceramic that people like to decorate with underglaze. 2. The ceramic tableware bought back should be soaked and boiled in 4 vinegar water, which can remove most of the toxic substances and greatly reduce the potential harm of ceramic white porcelin dinnerware to the human body. 3. Do not use ceramic tableware to store acidic foods and beverages such as juice, wine, coffee, etc. for a long time. Because the longer the ceramic tableware is to hold acidic food or beverage, the higher the temperature, the easier it is to dissolve lead, which is equal to aggravating the toxic and side effects of lead dissolution. 4. Whether the appearance is correct, whether there are damages, spots, bubbles, and smoothness. The lead in the glaze of chinaware ceramic with thorny, spotty, or even cracked surfaces is easy to overflow, so they are not suitable for tableware. 5. When choosing porcelains decorated with gold and silver, wipe it with your hands, and the color will not fade. 6. With a few taps, the sound is crisp and good quality, while dull or hoarse sound is inferior. 7. adhesives are mostly high in lead, and it is not suitable to make tableware after porcelain tableware repair. 8. The glaze on the surface of the porcelain is made by firing at a temperature above 800 degrees. If it does not reach 800 degrees, the low temperature glaze will be harmful to the human body. is good to reach 1350 degrees. 9. When purchasing a complete set of ceramic products, it is necessary to see whether the glaze color, picture, gloss, and style of each piece are consistent, well-proportioned and coordinated. 10. The thin ceramic products should have a sense of transparency, be thin and light, and have uniform thickness when they are looked after under sunlight or light. Precautions for using ceramic tableware Although ceramic tableware is beautiful and easy to use, there are still some things worthy of our attention when using ceramic tableware. Below we introduce the precautions for using ceramic white porcelin dinnerware. 1. Although the colored paintings on the inner walls of ceramic white porcelin dinnerware are bright and bright, the colored glaze contains heavy metal elements such as lead, mercury, and cadmium. Among them, cadmium and lead can easily cause liver or other internal organs poisoning, while mercury can cause liver and kidney cirrhosis. The more the ceramic glaze, the brighter the color, and the more compounds such as lead and cadmium. Don't pay too much attention to patterns when choosing ceramic tableware, especially don't use dishes with painted inner walls. The newly purchased tableware can be soaked in vinegar for 2~3 hours to dissolve the harmful substances in the colored glaze. In addition, the colored porcelain tableware must not be heated in a microwave oven. 2. The underglaze colored porcelain is safe, the pattern color is more blue and green, less red and yellow. The underglaze color is to paint first, then glazed, and then directly fired at high temperature. Because there is no need for low melting point substances, there is no need to add lead in the pigment, and the pigment is not easy to precipitate, which is safe; the in-glaze color is glazed first, Paint again, and then fired at high temperature. It does not contain lead, and the pigment is more difficult to precipitate and is relatively safe. The underglaze color has a patterned area that feels as smooth as other places, and the gloss is very good, while the underglaze color is somewhere in between. Although the gloss is better, the hand feel is not smooth.
