For ceramic tableware containing food, attention should be paid to the decoration of the contact surface with the food. For ceramic tableware used for acidic foods, products with less surface decoration patterns should be used. 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 and cadmium dissolution of such ceramic tableware products tends to be high. Pay special attention to the ceramic tableware that can be wiped off by hand. This product has high lead and cadmium dissolution. For unconcerned ceramic tableware, it can be soaked for several hours with vinegar. If it is found that the color changes obviously, it should be discarded. For products used in microwave ovens, products with metal decoration should be avoided, such as products with gold rim, silver edge or gold-plated paper, metal wire and wire mosaic. 2D Wireless Handheld Industrial Barcode Scanner Pos Therminal Barcode Reader,Industrial Qr Code Scanner,Barcode Scanner With Stand,Industrial Wireless Barcode Scanner Guangzhou Aigather Intelligent Technology Co., Ltd. , https://www.aigathergz.com
