Ceramic tableware should be good-looking but also anti-poisonous

In the ceramic production process, most of the lead and cadmium exceeding the standard are applique technology. In order to be beautiful, ceramic tableware has many brightly colored patterns. These all need appliques, bright colors and good gloss, and lead and cadmium need to be added. According to reports, ceramic tableware can be divided into three types: over-glaze, under-glaze, and in-glaze according to ceramic flower surface decoration. The overglaze technique is relatively simple and the price is relatively cheap. Lead, cadmium and other toxins in ceramic dishes are mainly from the pigments of the overglaze. Lead, mercury, and cadmium in the glaze are all harmful elements to the human body. Therefore, when choosing ceramic tableware, it is better not to use overglaze decoration, especially the inner wall of ceramic tableware. According to Hu Qun, professor of the Department of Pediatric Blood and Fluid Diseases of Wuhan Tongji Hospital, the amount of cadmium dissolved in excess of the standard will cause cadmium poisoning in the human body, and the amount of lead dissolved in the lung disease will cause lead poisoning in the human body. In severe cases, it can cause kidney failure, unresponsiveness, gout, and peripheral nervous system diseases. For children, the hazards of lead poisoning are particularly serious. It can affect the development of the brain at a low level, and at a high level, it can lead to increased intracranial pressure, vomiting, and convulsions. Not only colored porcelain, but unglazed white porcelain white porcelin dinnerware may also exceed the heavy metal standards. If the ceramic clay is not up to standard, it may cause lead poisoning and other diseases. According to relevant national regulations, if ceramic tableware is soaked in 4% acetic acid, the amount of lead dissolution shall not exceed 7 mg/L, and the amount of cadmium dissolution shall not exceed 0.5 mg/L. At present, the products of wholesale dinnerware suppliers basically meet this requirement. However, the quality of Sanwu ceramic products, especially the ceramic tableware sold in the booth, is often difficult to reach the standard, and the dissolved amount of lead and cadmium exceeds the prescribed index by 10 times, or even dozens of times. When choosing ceramic tableware, you should carefully observe whether the inner wall of the tableware is clean. Scrape with your nails. The patterned and unpatterned parts of the tableware reflect different light. The two parts feel different. The glaze can be scraped off with your nails. It is likely to be inferior to heavy metals. product. At the same time, in order to ensure safe use, ceramic tableware should be boiled for 5 minutes or soaked in white vinegar for 2 to 3 hours before using it to dissolve harmful substances in the ceramic tableware. If there is a significant change in color, it should be abandoned. Ceramic tableware manufacturers remind you: ceramic tableware should not be heated in a microwave oven, and ceramic tableware should not be used for long-term storage of acidic food, juice, wine, coffee and other beverages, because the longer the ceramic tableware is for acidic food or beverages, the higher the temperature , The easier it is to dissolve lead.
