1, the newly bought ceramic pot needs to be brushed with a hard brush; The pot wall has fine pores and good water absorption. The pot can be filled with clear water, let stand for 3 ~ 5 minutes, then wash and dry for later use. However, it should be noted that the soaking time should not be too long. Before you put ceramic pot on the fire, you should also dry the water outside the pot. When the newly bought casserole is used for the first time, it is best to cook porridge, or use it to cook thick rice washing water or noodle soup, so as to block the tiny pores of the casserole and prevent water seepage.
2. When using ceramic pot to make soup and stew, you should first put the water into the casserole, and then put the casserole on the fire, first with slow fire, then with strong fire; When cooking in a casserole, if there is less soup in the pot, you need to add water, not cold water, but warm water or hot water; At the same time, the soup in the pot can't overflow to prevent the water from bursting outside the pot.
3. If you use a coal stove for heating, you should prevent the ceramic pot bottom from colliding with coal.
Ceramic pot is fragile and easily broken, so handle it with care. The hot casserole that has just been used up is best placed on an iron frame or a dry wooden board or straw mat, not on the wetland, ceramic tile or cement floor, otherwise the temperature will suddenly change and the ceramic pot will easily burst.
5. Don't use ceramic pot to cook sticky food.
6. If the inner wall of the ceramic pot is colored, it is not suitable for storing wine, vinegar, acidic drinks and food.
7. The material of ceramic pot is special, so the casserole should be cleaned after cooling. Moreover, it can't be soaked with detergent to prevent sewage from infiltrating into ceramic pot's pores, and it can't be washed off. The washed ceramic pot can't be put away until the water is completely dry, otherwise it may grow black spot mold.
The traditional concept of ceramic tableware and ceramics refers to all artificial industrial products with inorganic non-metallic minerals such as clay as raw materials. It includes various products made of clay or clay-containing mixture through mixing, molding and calcination. The firing and application of ceramic tableware has a long history in China, and it is deeply loved by Chinese people because of its diverse shapes, bright colors, cool and smooth feel and easy washing. The production methods of ceramic tableware are divided into three types: over-glaze color, under-glaze color and in-glaze color. Ceramic tableware is mainly produced in Jingdezhen in Jiangxi, Zibo in Shandong, Tangshan in Hebei, Dehua in Fujian, Chaozhou in Guangdong and Liling in Hunan. Ceramic tableware can be divided into magnesium porcelain tableware, magnesium reinforced porcelain tableware, reinforced porcelain tableware, shell porcelain tableware, glazed porcelain tableware and elegant porcelain.

Various products are made by mixing, molding and calcining the compound. From the roughest earthenware to the finest exquisite ceramics, it belongs to its scope. Its main raw materials are silicate minerals (such as clay, feldspar, timely, etc. ) is taken from nature, so it belongs to the category of "silicate industry" together with glass, cement, enamel, refractory and other industries. The firing and application of ceramic tableware has a long history in China, and it is deeply loved by Chinese people because of its diverse shapes, bright colors, cool and smooth feel and easy washing. The production methods of ceramic tableware are divided into three types: over-glaze color, under-glaze color and in-glaze color. Over-glaze colored ceramics are made by pasting colored paper made of pigments on the glaze surface or painting directly on the surface of products with pigments, and then firing at low temperature. Because the firing temperature can't reach the melting degree of the glaze layer, the color surface can't sink into the glaze. Touching the glazed porcelain with your hand, you feel that the flower surface has obvious concave and convex feeling; The firing temperature of colored porcelain in glaze can melt the glaze and the pigment can sink into the glaze. After cooling, the product is covered by glaze layer, and the surface of the product is smooth, and there is no obvious concave-convex feeling when touched by hand. The underglaze colored ceramics are all decorated on the porcelain blank, glazed and then fired at high temperature once, and the flower surface is covered with glaze layer, which looks bright, flat and smooth.
Pay attention to the following points when buying and using ceramic tableware:
1, you must choose the regular market to buy ceramic tableware, and you must not buy inferior products without regular manufacturers for petty gain. 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. [3]
2. Pay attention to the color of tableware when buying, and touch the surface of tableware with your hands to see if the inner wall is smooth;
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.
