Mug Manufacturer Harm of cadmium and lead in ceramic coffee mugs

Ceramic Mug Group Key:Sublimation mug wholesale
From Ceramic Mug Group,Ceramic coffee mug, as we all know, the traditional concept of ceramics refers to all the artificial industrial products with clay and other inorganic non-metallic minerals as raw materials. It includes various products made of clay or mixture containing clay through mixing, forming and calcining, which are called ceramics.

Sublimation mug wholesale has become the first choice of tableware for many families because of its smooth color, bright color and exquisite design. But few people know that in order to ensure bright colors in the production process of ceramic mugs, lead, mercury, radium, cadmium and other harmful heavy metal elements are usually added to the colored glaze.

However, if milk and other foods containing organic acid are placed in amazon ceramic coffee mug with heavy metal exceeding the standard, the toxic substances in the ceramic mug will be released and enter the human body together with the food, causing chronic poisoning, in which cadmium and lead may cause liver or other internal organs poisoning, mercury may cause liver and kidney hardening, and radium may kill white blood cells. In addition, in addition to the colored porcelain, the white porcelain without colored glaze may also have excessive heavy metals. If the clay used to make the porcelain is unqualified, lead poisoning and other diseases may be caused.

Therefore, when purchasing ceramic mugs, we should carefully observe whether the inner wall of tableware is smooth and clean, and use nails to scrape. If there is a pattern on the ceramic mug and the part without a pattern has different refraction light, the two parts have different handfeel, and the glaze color can be scraped off with nails, it is likely that the inferior products with excessive heavy metal can not be used to hold food. At the same time, in order to ensure safety, the ceramic tableware should be boiled for 5 minutes before use, or soaked in vinegar for 2-3 hours to dissolve the harmful substances in the ceramic tableware. In addition, white porcelain should be soaked in white vinegar, and colored porcelain should not be heated in microwave oven. Why the color porcelain should not be heated in the microwave oven, because the color painting on the inner wall of the color tableware is bright, but the color glaze contains lead, mercury, cadmium and other heavy metal elements. Among them, cadmium and lead are easy to cause liver or other visceral poisoning, while Mercury can cause liver and kidney sclerosis. The more the glaze color of the ceramic cup, the brighter the color, the more lead, cadmium and other compounds.Sublimation mug suppliers

It is understood that in the production process of ceramic mug, lead is added to the glaze and lead and cadmium are added to the pigment, which can make the glaze uniform and bright. However, there are serious defects in the raw materials and processes of some small ceramic production workshops. In order to pursue low cost, the physical and chemical indexes of daily ceramic products, especially the indexes of lead and cadmium, often do not meet the product quality and safety standards.

Therefore, the industrial and commercial personnel remind consumers: when purchasing ceramic products, they should 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, and the amount of lead and cadmium dissolved in such ceramic products is often high. Especially those ceramic tableware that can wipe off the pattern by hand, it is better not to buy.
