Gradually, many businesses produce ceramic dinnerware without permission. Since there is no one to test, the quality of ceramics is uneven in the absence of supervision. Some ceramic dinnerware is very poor, and there are more harmful substances in the dinnerware. Therefore, when buying ceramic dinnerware, you must go to the regular market to buy, so as not to buy fake and inferior products.
When buying ceramic dinnerware, try to minimize the selection of dinnerware with bright patterns or too many patterns, because the materials used for pattern depiction, after certain processing procedures, make dinnerware contain mercury and other harmful substances. Therefore, the more plain the color of the pattern of the dinnerware, the better, and the less the pattern, the better.
If you find that the utensils you purchased contain odors, or if they still have a strong odor after washing, then please do not use the ceramic utensils again. Because no matter what the substance contained in its odor, the odor will affect people's appetite and even be detrimental to human health.
Finally, when buying ceramic dinnerware, touch the inner wall of the dinnerware with your hands to see if the dinnerware is smooth. If the surface of the dinnerware is too rough, then do not use this kind of ceramic dinnerware. At the same time, when the dinnerware is bought home, it must be soaked in hot water for a period of time, and then put in the disinfection cabinet for disinfection before it can be used.
The beautiful shape of ceramic dinnerware can increase the beauty and promote people's appetite, but if the ceramic dinnerware is used improperly, it will affect the physical and mental health of the human body. Many people may have some doubts about painted ceramics. The colorful paints are oxides of various metals, and there will be certain corrosion in the daily items containing acid and alkali.
If the ceramic dinnerware is decorated with paint, underglaze is safer than overglaze. It is recommended that the glazed utensils only be used for decoration or placing fruits, and avoid heat or soaking in water and oil. Medium temperature china or some low cost pottery is also used. So buy porcelain in your life and avoid buying some rare and cheap foreign trade porcelain with hand-painted patterns.
