Classification of porcelain tableware:

Hotel porcelain tableware can be classified according to porcelain classification or production method, and can also be classified according to function.

2. According to the production method, it is divided into over-glaze colored porcelain, in-glaze colored porcelain and under-glaze colored porcelain.

3. Classification by function: table decoration tableware, kitchen tableware, etc.

Classification of ceramic tableware

Grade 1: the whole product is free from defects, deformation and chromatic aberration, and pinholes are allowed in inconspicuous places;

Grade 2: 2-3 pinholes, no obvious color difference and slight hair shape;

Grade 3 (nearly defective): the color difference is obviously slightly deformed, and the glaze shrinkage of about 1-2 is allowed.

Pay attention to the following points when buying porcelain tableware:

1. Be sure to choose a regular market. First, you can check the product name and grade indicated on the product packaging box or the documents in the box. According to the national regulations, when ceramic tableware is soaked in 4% acetic acid, the dissolution amount of lead should not be greater than 7 mg/L, and the dissolution amount of cadmium should not be greater than 0.5 mg/L. The products of regular manufacturers can basically meet this requirement.

2. Pay attention to the color of tableware, touch the surface with your hands to see if the inner wall is smooth and the shape is geometric; Ceramic products with prickly, mottled and even cracked surfaces are easy to overflow lead in their glazes and are not suitable for tableware.

3. Smell it with your nose if there is an odor;

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, so the brighter the color of tableware, the easier it is for heavy metals to exceed the standard;

5, should choose and buy raw materials, process control strictly underglaze tableware.

Discrimination of ceramic tableware

We can distinguish porcelain tableware by watching, listening, comparing and trying. The specific method is as follows:

1, look

It is to carefully observe porcelain from top to bottom and from inside to outside. See if the enamel is smooth and smooth, with or without scratches, holes, black spots and bubbles; Second, see if the shape is regular and deformed; Third, look at the picture without loss; Fourth, to see if the bottom is flat, it must be placed smoothly without burrs.

Step 2 listen

This is the sound of you listening to porcelain knocking. If the sound is crisp and pleasant, it means that the porcelain tire is fine and dense without cracks. When fired at high temperature, porcelain is complete and of good quality.

3, than

Is to compare. For matching porcelain, it is necessary to compare accessories to see whether their shapes and picture decoration are coordinated. Especially a complete set of blue-and-white or blue-and-white exquisite porcelain, because the color of blue-and-white varies with the firing temperature, which is both blue-and-white porcelain and deep and light in color. A set of several or even dozens of complete sets of cold porcelain, if the blue and white colors are obviously different, this set of porcelain will be greatly inferior.

Step 4 try

Is to try to cover, try to install, try to test. Some porcelains have covers, and some porcelains are made up of several parts. When choosing porcelain, don't forget to try to cover it and assemble the parts to see if it fits.
