When Consumers Buy Ceramic Products Beware of Excessive Heavy Metal Content
Nowadays, there are many kinds of ceramic products on the market, and the range of choice is too great. Qijia reminds everyone that when choosing ceramic products, don’t be blinded by the glamorous appearance fans, and beware of excessive heavy metals in the ceramic products that endanger family health. In the purchase, we must first look at the glaze, the screen is clear, neat and shiny; whether the various sets of patterns are consistent, coordinated, supporting; at the same time, you can see how transparent the porcelain is to the sun or the light, and the transparency is good. In addition, the most important point is that consumers pay attention to the lead content of ceramic eating utensils, and daily ceramic eating utensils are mostly decorated with floral decorations, and most of them are decorated with glazes, and there are mainly decorative methods such as glaze, glaze and glaze. Different decorative methods have great differences in the content of heavy metals such as lead and cadmium. If foods containing high levels of lead and cadmium are consumed for a long time, lead will be deposited in the blood, causing damage to the central nervous system, kidneys, and other organs. This will also have adverse effects on the intellectual development of children and adolescents. At present, the content of lead and cadmium in glazes, underglazes, and most color-glazed porcelains and white porcelains is very low, and the glaze ceramics use inferior pigments in the processing of ceramic flower paper, or in flower design. On the other hand, excessive use of pigments containing high amounts of lead and cadmium, or insufficient temperature and ventilation during baking, can easily lead to excessive levels of lead and cadmium elution. Some white porcelains are mainly unpolished asbestos. Since leaded frit glazes are used, if the firing process is not strictly controlled by the process conditions of the bone china, there is a great possibility that the amount of lead elution exceeds the standard. Therefore, in order to reduce the influence of lead content in ceramics, the following points should be noted when purchasing: (1) For utensils containing foods, attention should be paid to the decoration of the contact surface with food, and as far as possible, no glaze products should be used. (2) For containers containing acidic foods, try to use products with less surface decoration. (3) When purchasing, you should also pay attention to whether the color of the pattern is bright. If it is not bright, it may be that the temperature during baking does not meet the requirements. The lead and cadmium elution of such products is often high. (4) Pay special attention to those products that can be wiped off by hand. The lead and cadmium dissolution of this product is extremely high. (5) For products that are not at ease, they can be soaked in vinegar for several hours. If there is a noticeable change in color, they should be discarded.
