Ceramic Mug: It Is Better To Choose Underglaze Color

Colorful ceramic water cups are very flattering, but in fact there are huge hidden dangers hidden in those bright paints. The inner wall of a cheap colored ceramic cup is usually coated with a layer of glaze. When the glazed cup is filled with boiling water or acidic or alkaline beverages, some aluminum and other heavy metal toxic elements in the glaze are easily precipitated and dissolved into the liquid. At this time, people drink the liquid with chemical substances, and the human body will be hurt. It is best to choose natural color cups when using ceramic cups. If you can’t resist the temptation of colors, reach out and touch the surface of the color. If the surface is smooth, it means that it is underglaze color or in-glaze color, which is relatively safe; If there will be falling off, it means that it is glaze color, so it is best not to buy it.
