Do You Really Know How to Use Ceramic Tableware?
Many people start to use the newly bought ceramic tableware after washing them with water. This practice is very bad. Because ceramic tableware contains heavy metals, it is the main culprit that endangers health. If it is not properly processed, heavy metals will enter the human body along with the food, which will cause chronic heavy metal poisoning, decreased immunity, and blood system diseases over time.
So, what should I do with the newly purchased ceramic tableware before use? Experts suggest that after buying back the porcelain tableware, it is recommended to boil the tableware in boiling water for 5 minutes. The boiling water can have a sterilization effect, and then soak it in vinegar at room temperature for 1-2 hours. Because when ceramics meet acidic substances, some of the toxic precipitation. For tableware that is not assured, soak it in vinegar for a few hours. If you find that the color changes significantly, you should discard it.
When cleaning ceramic tableware, use a soft cloth, and scouring pads, decontamination powder, etc. are easy to scratch the surface of the tableware and are more susceptible to contamination. It is best not to use them. At the same time, try not to store acidic, oily, and alkaline foods for a long time during use, and especially do not heat porcelain tableware with oily foods in a microwave to prevent the precipitation of toxic substances.
In addition, when buying ceramic tableware, you must first pay attention to whether the tableware is marked with the name of the factory, the implementation standards, etc.; secondly, you must touch it with your hands to see whether the inner wall is clean, whether there are cracks, convexities and inequalities; in addition, smell it. It should be noted that do not choose brightly colored and dark colored tableware, and it is best not to buy those with flowers inside.
In the production process, porcelain tableware is divided into three types: over-glaze, mid-glaze, and under-glaze. Over-glaze color is applied on the glaze, that is, baked after decaling paper on the surface of the burnt white porcelain. Under-glaze color is applied under the glaze, the color is covered by the glaze layer, and the color in the glaze is mixed with colors. As colored glaze pigments contain harmful metals such as lead and cadmium, in comparison, the production cost of overglaze is lower, and underglaze is safer. Long-term use of on-glaze craftsmanship contains tableware with high organic acid content such as vinegar and vegetables. Heavy metals will enter the human body along with it. Over time, it will cause chronic heavy metal poisoning, decreased immunity, and blood system diseases.
Therefore, do not use overglaze decoration when choosing ceramic tableware, especially the inner wall of ceramic tableware. It can be decorated with underglaze or midglaze. For example, blue and white is a kind of ceramic that people like to decorate with underglaze.
