How is the blue pattern on blue and white porcelain formed?

The blue pattern on blue-and-white porcelain is made of cobalt ore containing cobalt oxide, coated on the ceramic body, coated with a layer of transparent glaze, and sintered at one time by high temperature reducing flame.

The blue color of blue and white porcelain comes from the blue material used in painting. The main component of green material is cobalt oxide, which will react chemically after high temperature baking, thus producing blue. In fact, green materials contain different proportions of cobalt, which also affects the depth of blue. The higher the cobalt content, the brighter the color.

Besides cobalt content, firing temperature also plays an important role in the color of blue and white porcelain. Only by firing at the right temperature can pure blue and white porcelain be burned. If the temperature is too low, the blue color may appear dim and weak; And if the temperature is too high, the blue color may become too deep. Therefore, mastering the firing temperature is one of the keys to making blue and white porcelain.

The process of making blue-and-white porcelain is also a unique art. First, the pottery trade union will burn the white blank into a finished product. Then, the painter will draw patterns on the finished product with special blue pigments. This process requires great skill and patience, because each stroke determines the beauty and ugliness of the final work.

After painting, the blue and white porcelain is fired again. In this process, ceramic works will be put into a kiln for high-temperature firing. At high temperature, the green substance reacts chemically, and the blue color released by cobalt oxide can really form. By firing, the glaze on the ceramic surface will become smooth and give the work a better texture.

Blue and white porcelain has a long history and unique skills. From the choice of green materials to the mastery of firing temperature, every step requires the craftsman's exquisite skills and rich experience. They created unique blue and white porcelain works with their hearts and wisdom.

Both the blue pattern of blue-and-white porcelain and the whole production process show the improvement of traditional ceramic technology in China. This perfect combination of chemical reaction and aesthetics not only endows blue-and-white porcelain with profound charm, but also makes it a unique existence in intangible culture.

Behind every blue-and-white porcelain work is the painstaking efforts and wisdom of countless craftsmen. Let's cherish these traditional crafts and protect our cultural heritage. While appreciating the beauty of blue and white porcelain, we also feel the scientific miracle and artistic beauty contained in it.

Generation age

Blue and white porcelain began to rise in the Tang Dynasty. Archaeological evidence in Yangzhou and Luoyang shows that at least in the Tang Dynasty, white and blue flowers have appeared. Blue-and-white porcelain gradually matured in the Yuan Dynasty, and in the Ming Dynasty, blue-and-white porcelain became the mainstream of porcelain. Blue and white porcelain reached its peak in Kangxi period of Qing Dynasty. Blue and white porcelain is a kind of high-temperature underglaze porcelain with blue and white background, which originated in the Tang Dynasty.

Blue-and-white porcelain varieties are fresh and lively, but at the same time they are simple and elegant, which is regarded as the representative of the aesthetic concept of the Chinese nation. Blue-and-white porcelain in Tang Dynasty has a heavy carcass, loose texture and pure white color. But by the Yuan Dynasty, the production technology of blue and white porcelain had been quite sophisticated. At this time, the porcelain was beautiful in shape and dense in composition, which showed the superb painting ability of craftsmen in Yuan Dynasty.
