First, let's look at the level of ceramic tableware,Ceramic tableware is generally divided into:

(1) Level 1: the whole product is free of any defect, deformation or color difference, and a pinhole is allowed in an inconspicuous place;

(2) Grade 2: there can be 2-3 pinholes, no obvious color difference and slight deformation;

(3) Grade 3 (near defective): the color difference is obvious and slightly deformed, and the shrinkage glaze of about 1 square mm at 1-2 places is allowed.

When we choose ceramic tableware, we should pay attention to the following points:

1. When buying ceramic tableware, we must choose the formal market. We must not buy low-quality products without formal manufacturers. According to national regulations, when ceramic tableware is soaked in 4% acetic acid, the dissolution of Lead shall not be greater than 7 mg / L and cadmium shall not be greater than 0.5 mg / L. 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;

3. Smell with your nose for peculiar smell;

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

5. Should buy raw materials, process control more strict in glaze color, underglaze color tableware.

Points to note:

1. The bought ceramic tableware shall be soaked and boiled with 4 vinegar water first, which can remove most of the toxic substances and greatly reduce the potential harm of ceramic tableware to human body.

2. Most porcelain adhesives contain high lead, and porcelain should not be used as tableware after mending.

3. Do not store acidic food, fruit juice, wine, coffee and other drinks with ceramic tableware for a long time. Because the longer the ceramic tableware holds acidic food or beverage and the higher the temperature, the easier it is to dissolve lead, which is equal to aggravating the toxic and side effects of lead dissolution.
