From Xinxiang Ceramic Mug Manufacturers,To judge whether the ceramic tableware contains toxic substances, it is necessary to distinguish which kind of sublimation mug manufacturers is used: underglaze color, underglaze color and overglaze color.

How to distinguish overglaze color, in glaze color and underglaze color?

Generally speaking, ceramic tableware is toxic, which belongs to the category of glaze color. Because the patterns or patterns on the glaze color tableware can be scraped off with a knife, or even soluble in water, and the pigments used to make patterns or patterns are toxic.

OK, there's a problem. If the patterns or patterns on the tableware are on the surface of the tableware, those that can be scraped off with a knife or sharp tool are likely to eat toxic substances in the process of use.
