Do you know these ceramics purchase tips?
Ceramic catering appliances are easy to clean, acid and alkali resistant, convenient for high temperature sterilization and steaming, boiling, roasting, and roasting food. The high-grade ceramic utensils with beautiful appearance and beautiful decoration are not only practical, but also artistic and enjoyable. They are essential for daily life. Jiuzheng Building Materials Network Tips: When choosing ceramic products, consumers should pay attention to the following matters:
Appearance Quality
Consumers can first check the product name and grade indicated in the product packaging box or the documents in the box; secondly, the physical quality of the product can be observed by naked eyes. When purchasing, try to select products with no obvious defects and regular shapes. For disc and bowl products, several products of the same size and size can be stacked together to observe the distance between them, and the distance is not uniform, indicating that the shape of the device is irregular and the deformation is large. For a single product, it can be laid flat or reversed on the glass to see if it fits into the glass to determine its deformation. For porcelain products, hold them on your hands and tap the edges with your fingers. If there is a hoarse sound, there is a crack.
Lead and cadmium dissolution
The amount of lead dissolved in the glaze color products and the underglaze products, and the amount of cadmium dissolved are extremely little or almost no, and can be purchased with confidence. For the purchase of glaze color products, please refer to the following methods:
1. For utensils containing food, products with less decorative patterns on the surface of the food should be used.
2. Pay attention to whether the pattern color is bright. If it is not bright, it may be that the temperature does not meet the requirements when baking flowers. The lead dissolution amount and/or cadmium dissolution amount of such products tends to be high.
3. Pay special attention to products that can be wiped off by hand. The lead dissolution or / and cadmium dissolution of these products are extremely high.
4. For products that are not at ease, you can soak them in vinegar for a few hours. If you notice obvious changes in color, you should discard them.
