1. It is "see", not the 陶瓷碗 defective bowl. Pick up the bowl and aim it at the light. Under the light, any blemishes on the bowl body can be clearly seen. If there are bubbles, bulges on the bowl, or uneven bottom of the bowl, it is generally a defective product.

2. "Touch" with your hands to see if the surface is rough or smooth. When buying a bowl, touch it with your hand. If the surface of the bowl is rough and uneven, it is a relatively inferior bowl and it is not recommended to buy it. In addition, you can feel the pattern on the bowl. If it is raised, it is overglaze. This type of bowl is not recommended.

3. Buckle the bowl on the table to see if the mouth of the bowl is flat and there is no problem with it being tilted. In addition, if the bowls of the same type are stacked together, if the bowl and the bowl can fit closely, it means that the bowl is of good quality and is a high-quality bowl.

4. It is "listening", that is, listening to the sound made when the porcelain is lightly tapped. If the sound is crisp and pleasant to the ear, it means that the porcelain body is fine and compact, without cracks, and is completely porcelainized when it is fired at high temperature. If the voice is dumb, it can be concluded that the porcelain body is cracked or the porcelain is incomplete. This kind of porcelain is easy to crack due to changes in cold and heat.

5. Buy bowls with few plain patterns. Modern people like beauty, and tableware also pursues exquisiteness. Many people like to have patterns when they choose bowls. In fact, the more patterns on the bowl, the more toxic substances will be. Therefore, try to choose the ones with less patterns. It is best to have no patterns in the healthiest.

Be careful with the painted ceramic bowls on the inner wall

Ceramic tableware contains heavy metal elements such as lead, mercury, and cadmium, which can easily cause liver poisoning and renal cirrhosis. These harmful metals mainly come from the painted on the inner wall. Therefore, the more the ceramic glaze, the more compounds such as lead and cadmium. When using ceramic tableware, do not use bowls and dishes with painted inner walls to serve rice or soup, and try not to heat them in a microwave oven.

Underglaze porcelain is the safest

Because the underglaze color is painted first, there is no need to add lead in the pigment, and the underglaze color is finished after the glaze is applied, and the pigment contains lead. Compared with in-glaze colors, under-glaze colors are not easy to separate out and are relatively safer. It is recommended to purchase and use. Wash it with hot water before use, and then soak it in vinegar to filter out harmful metals.

Microwave heating avoids metal decoration

If the ceramic tableware must be heated in a microwave oven, be careful not to use metal decorated ceramic tableware, because the ceramic tableware with metal edges will precipitate toxic substances when heated in the microwave oven.
