Safety precautions for using melamine tableware. Good melamine tableware is ceramic, glass, enamel, porcelain, and plastic tableware, which affect health. Please pay attention when buying.
Manufacture of melamine tableware color glaze, glaze color and glaze color. The paper made of colored glaze ceramic pigment is pasted on the glaze surface or painted directly on the surface of the product, and then baked at low temperature. The glaze layer will not melt, and the flowers will not sink into the glaze. The ceramic flower surface feels obvious concave when touching the glaze . The baking temperature of glazed ceramics can melt the glaze and the pigment can enter the glaze. After the glaze layer is cooled, the surface of the product is smooth without concavity. After being fired at high temperature, the surface of the glaze layer is covered by fresh flowers, and the surface is bright, smooth and smooth.
Harmful metals mainly come from glazes. The radioactive element radium kills white blood cells. Cadmium, lead, and mercury are all heavy metals. Cadmium and lead can cause liver or other internal organ poisoning, while mercury can cause liver and kidney cirrhosis. Long-term use of glazed tableware, such as vinegar, wine, fruit juice, vegetables and other foods that contain high levels of organic acids, such as vegetables, will cause heavy metals such as lead in the tableware to enter the human body and enter the human body together with the food. A long time will lead to slow heavy metal poisoning.
In order to reduce costs, some small ceramic manufacturers purchase raw materials with high lead and cadmium content and unstable functions. In the production process, due to the large decorative area, low baking temperature, and improper processing by the workers, the lead-dissolved ceramic products are unqualified. That is to say, some individuals and private enterprises, in order to earn more profits, shorten the baking time, lower the baking temperature, and shorten the time of using the old oven, relying on the experience of the workers, which seriously restricts the quality of melamine tableware.
