Check whether the ceramic glaze surface is smooth and smooth, whether there are scratches, small holes, black spots and air bubbles; second, check whether the shape is regular and whether there is deformation; third, check whether the picture is defective; glitch.
“Listen” is to listen to the sound when the ceramic is tapped lightly. If the sound is crisp and pleasant, it means that the porcelain body is fine and dense, without cracks and damage, and the porcelain is completely transformed when fired at high temperature. If the sound is hoarse, it can be concluded that the porcelain body is cracked or damaged, or the porcelain is not complete.
“Compare” is to compare. For the matching ceramics, it is necessary to compare the accessories to see whether the shape and picture decoration are consistent. Especially the complete set of blue and white or blue and white porcelain, because the color of blue and white changes with the firing temperature, so the same blue and white porcelain, the color is dark or light, a set of several or even dozens of cold ceramics, such as each piece of blue and white. There are obvious differences in color, and this set of ceramics is greatly inferior.
“Try” means to test the cover, test the installation, and test. Some ceramics have lids, and some ceramics are composed of several components. When choosing ceramics, don’t forget to try to cover the lids and try to assemble the components to see if they are suitable.

However, the glaze on the ceramic surface has the potential to be a health killer. Lead, mercury, radium, cadmium, etc. in colored glaze are all elements that are harmful to the body. The radioactive element radium kills white blood cells. Cadmium, lead and mercury are heavy metals, cadmium and lead can cause poisoning, mercury can cause hardening. When using unqualified ceramic products, these harmful substances will dissolve, and as food enters the human body, it will cause chronic poisoning for a long time. At the same time, attention should also be paid to the clay used for making ceramics. Poor quality clay contains a lot of microorganisms and harmful substances. Even if it is not painted with color glaze, it will damage human health. Therefore, the specifications and quality of the products are particularly important. The color-glazed ceramics that meet the standards are basically harmless to the human body, while the colorless ceramic tableware that looks clean may bury hidden dangers for health.
