Characteristics of traditional pottery in Rizhao

Traditional custom red represents auspiciousness and wealth, glaze red is steady and sincere, magnificent and simple, and is deeply loved by joy, pleasure, calmness and enthusiasm.

Modern ceramic art: creating the creative subject, exerting imagination and realizing the spiritual value of the body. The media regards the ceramic art house of ancient art and modern ceramic clay sculpture as material carriers, but it embodies the spirit of modern art and advocates free creation and sexual play. Even though some works still retain the purpose of container form, they break through the original technical specifications, abandon the exquisiteness and regularity of traditional ceramics, and say that the classical aesthetic taste is more free and imaginative. More cultural spirit is needed to develop modern ceramic art and create artistic bottles and jars with traditional significance. Even if bottles and jars are artistic concepts, they are free to express the experience of ceramists. Modern ceramic art is purely the decent spirit of artists. Artistic creation has the characteristics of detachment, independence and pure art of ancient ceramic matrix.

In some cases, clinker or sand is added to clay to reduce shrinkage. The firing temperature of some products will change according to the nature of impurities contained in clay lumps and the porosity of bricks, so the frost resistance of bricks is low and forks are easy to hang on mortar. The water absorption should be kept between 5 ~ 15%. The color of brick is determined by the content of colored oxide in clay. When the oxidation flame burns, the combustion atmosphere is yellow or red, and when the original flame burns, it is blue or black.

Our building materials are blue bricks, that is, using yellow or red clay containing fe2o 3 as raw materials, the original FeON blue pottery, ordinary pottery and refined pottery of Fe2O3 are fired with the original flame, that is, porous colored bodies such as pottery pots, jars, urns and refractory bricks. The water absorption of the fine ceramic blank is still 4 ~ 1.2%, and the white glaze is lead-boron white. Compared with stoneware, the melting temperature is over 65440. Compared with porcelain, it has lower requirements for raw materials, lower plasticity, lower firing temperature and easy deformation. The process of filling bowls is simpler. Fine pottery has the same mechanical strength and impact strength as porcelain. Stoneware is softer than the glaze of the product. If the glaze layer damages the hole blank, it is easy to stain and affect health.

Fine pottery is assembled according to the body: clay, calcareous stone, clinker and other four kinds of clay fine pottery are close to ordinary pottery. The quality of limestone flux used in lime fine pottery is similar to that used in stone fine pottery, which has been replaced by less stone fine pottery. It is called hard fine pottery. Flux pottery perfectly uses all kinds of tableware (cups, plates, etc.). ) and sanitary pottery instead of expensive porcelain. Adding a certain amount of clinker to the fine ceramic blank can reduce shrinkage and avoid waste products.

Stoneware, as I said in ancient books, the compactness of stone-tire porcelain blank has completely reached the sintering point, which is close to the vitrified porcelain blank. The transparent whiteness of the porcelain blank is still 2% water absorption, which can make the raw materials burn color, and stoneware is easy to get high raw materials for porcelain making. High strength, good thermal stability, suitable for modern mechanized washing, and can pass through the refrigerator smoothly. The temperature of the oven changes rapidly in the international market. Due to the developed tourism, stoneware is much more sold than pottery.

Semi-porcelain body is close to porcelain body, and its water absorption rate is 3 ~ 5% (the water absorption rate of real porcelain is 0.5%). The performance of porcelain is better than that of fine pottery.

At the higher stage of ceramic development, the green body has been completely sintered and vitrified, and dense liquid and gas are permeable. The translucent part of the star in the thin tire is like a shell, and the tongue is smooth and sticky. The ceramic properties of hard porcelain are used to make advanced utensils, such as electric porcelain and chemical porcelain.

Soft porcelain flux has low firing temperature, low mechanical strength, low thermal stability, high transparency and strong decoration compared with hard porcelain. As for sintered porcelain and bone porcelain, the firing temperature is similar to that of soft porcelain, and its advantages and disadvantages are similar to that of soft porcelain. Both kinds of porcelain belong to soft porcelain, because it is difficult to make (the plastic dry strength of the blank is poor, and the firing deformation is serious), so the output is relatively high. The common British ashes porcelain is famous in Tangshan.

With the rapid development of modern electrical appliances, electronics, aviation, primary energy, metallurgy, machinery, chemistry and other industries, as well as the development of cutting-edge technologies such as computers, space technology and new energy power generation, special ceramics have been developed. The main raw materials for ceramics are clay stone, timely blank, clay or stone and pure oxide. The manufacturing process and performance requirements of raw materials with special properties are the same.

I suggest checking the information.

I feel that the thinking of asking questions is not very clear.
