Ceramic tableware is not only of practical value, but also of artistic value. It is made of clay or a mixture containing clay by mixing. It has diverse shapes, colorful, cool and smooth feel, and is deeply loved by the majority of families. What are the characteristics of ceramic tableware? What kinds of ceramic tableware are there? What are the hazards of ceramic tableware? Let's get to know!

Characteristics of ceramic tableware

Ceramic tableware has various shapes, delicate and smooth, bright colors and is easy to clean. It is the first choice for most families to buy Tableware. However, the colored glaze on the ceramic surface may become a health killer. Lead, mercury, radium, cadmium and other elements in colored glaze are harmful to the body. The radioactive element radium will kill white blood cells. Cadmium, lead and mercury are heavy metals. Cadmium and lead can cause liver or other visceral poisoning, and mercury can cause liver and kidney sclerosis.

When using unqualified ceramic products, these harmful substances will dissolve out. As food enters the human body, it will cause chronic poisoning over time. At the same time, we should also pay attention to the clay for making ceramics. Poor clay contains more microorganisms and harmful substances, which will damage human health even if it is not glazed. Therefore, the specification and quality of products are particularly important. The standard colored glazed ceramics are basically harmless to human body, while the clean looking achromatic ceramic tableware may lay hidden dangers for health.

When buying ceramic tableware, you should pay attention to the following points:

1. When buying ceramic tableware, we must choose the formal market, and we must not buy low-quality products without formal manufacturers. The state stipulates that when ceramic tableware is soaked in 4% acetic acid, the dissolution of Lead shall not be greater than 7 mg / L, and the dissolution of cadmium shall not be greater than 0. 5 mg / L. At present, the products of regular manufacturers can basically meet this requirement;

2. Pay attention to the quality of tableware when buying. Touch the surface of tableware with your hand to see whether the inner wall is smooth and clean;

3. Smell with your nose for any peculiar smell;

4. Don't buy Ceramic tableware with too bright colors. In order to make the color bright, manufacturers will add some heavy metal additives to the glaze. Therefore, the brighter the color of tableware, the more likely it is to exceed the standard of heavy metals;

5. You should buy the tableware with in glaze and under glaze colors with strict raw materials and process control.

What kinds of ceramic tableware are there

Generally speaking, ceramic tableware is divided into five categories, namely shell porcelain tableware, reinforced porcelain tableware, magnesium porcelain tableware, magnesium reinforced porcelain tableware and colored glazed porcelain tableware.

2. Magnesium reinforced porcelain tableware

Magnesium reinforced porcelain tableware, which uses magnesium stone powder as the main raw material, has the advantages of ultra-high strength, low brittleness, high whiteness and smooth glaze. It is also an ideal product for disinfecting tableware. However, the value of magnesium reinforced porcelain tableware is higher than that of magnesium porcelain tableware. The main reasons are longer service life, low damage rate, high grade and good image.

3. Reinforced porcelain tableware

Reinforced porcelain is made by firing high-quality porcelain clay with aluminum and magnesium. It has the characteristics of impact resistance and fine hand feel. However, the reinforced porcelain is dark and not very beautiful, and has been gradually replaced by magnesium reinforced porcelain and magnesium porcelain.
