Removing toxic substances with vinegar in ceramic mugs

Ceramic Mug    From:Xinxiang Ceramic Mug Manufacturers     2020-2-22
From Xinxiang Ceramic Mug Manufacturers,Entering the supermarket, the porcelain cups with different colors and designs on the shelves will attract many people's attention. But when people buy, they only look at its beautiful appearance and bright colors, but ignore the health risks.

"Heavy metals are responsible for the health hazards of porcelain cups." Dong Jinshi, vice president of the International Food Packaging Association, pointed out that in the production process, there are three kinds of porcelain cups: overglaze color, underglaze color and underglaze color. The overglaze color is the overglaze color, that is, it is baked after the white porcelain surface is pasted with decal paper. The underglaze color is the underglaze color, the color is covered by the glaze layer, and the underglaze color is a mixture of colors. Because of the harmful metals such as lead and cadmium contained in the color glaze pigment, the production cost of the overglaze color is lower and the underglaze color is safer. The tableware made by long-term use of glaze color technology contains food with high content of organic acids such as vinegar and vegetables. Heavy metals will enter the human body together, which will cause chronic heavy metal poisoning, immune decline and blood system diseases over time.

Dong Jinshi reminded us that when purchasing ceramic cups, first of all, we should pay attention to whether the name of the factory and the executive standard are marked on the tableware; second, we should touch the inner wall with our hands to see whether it is smooth and clean, whether there are cracks, convex and concave inequalities; in addition, we should smell whether there is a peculiar smell. It should be noted that do not choose the tableware with bright colors and deep colors, and do not buy the tableware with flowers.

After buying back the ceramic coffee cup factory, it is suggested to boil the tableware with boiling water for 5 minutes first. Boiling water can play a role in sterilization, and then soak it in the vinegar at normal temperature for 1-2 hours, because some toxic substances will be separated out when the ceramic encounters acid substances. For the tableware that is not reassured, it can be soaked in vinegar for several hours. If it is found that the color changes obviously, it should be discarded.

When cleaning ceramic tableware, soft dishcloth shall be used, while Baijie cloth, decontamination powder, etc. are easy to scratch the tableware surface, which is more susceptible to pollution, so it is better not to use them. At the same time, try not to put acid, oil and alkaline food in the use for a long time, especially do not put the porcelain tableware containing more oil in the microwave oven to heat, in order to prevent the release of toxic substances. If you want to put it in the microwave oven, you should avoid metal decoration, such as porcelain tableware with gold edge, silver edge or inlaid pattern with gold paper, metal wire and metal wire.
