Ceramic tableware, the traditional concept of ceramics refers to all man-made industrial products with clay and other inorganic non-metallic minerals as raw materials. It includes various products made of clay or clay containing mixtures by mixing, shaping and calcining. It ranges from the roughest pottery to the finest pottery and porcelain. The firing and application of ceramic tableware has a long history in China. It has a variety of shapes, colorful colors, cool and smooth feel, easy to wash, and is popular with the Chinese people. The production methods of ceramic tableware are divided into overglaze color, underglaze color and underglaze color. What should we pay attention to when choosing ceramic tableware? What kind of tableware should I buy?
1. Do not use ceramic tableware with unsmooth surface.
If the dragon on the old surface of desert ceramics is prominent, it can be simply judged as overglaze color, but the specific surface and glaze are smooth. If it is rough, it means that it is "not cooked". It is better not to buy such products. If you are very concerned about lead and steel, you should avoid buying tableware with flowers or flowers on the inner wall. Qualified products, though impossible, are safer.
2. No pores on the surface.
In addition to safety, the performance of ceramic tableware can not be ignored. The tableware can be placed obliquely under the light, so that the light is on top and the filling shortage is clear at a glance. All surfaces have holes, bulges, uneven tongue and cup bottom. These problems will cause inconvenience for future cleaning, so it is better not to buy them.
3. Do not buckle uneven ceramic tableware.
The flatness of these products, such as bowls and pints, should also be checked, and there are strict regulations in national standards. You can pour the tableware on a flat glass table to see if the mouth of the tableware is warped. You can also fold the same bowl and cup together. Products with good appearance should be closely combined. However, poor quality ceramic tableware may be bent or even stacked.
4. If the knocking is not brittle and the knocking sound is not clear, do not do it.
Good ceramic tableware has a clear and pleasant sound. Some ceramic dishes only have cracks, and the surface is invisible. Knock on the door before buying. If it makes a muddy sound, you can easily distinguish it.
