Ceramics is the origin of people's manual labor, the development of ceramic craftsmanship is with the accumulation of experience of the craftsmen. History Shen accumulation, Gaochun Porcelain craftsmen have created ceramics "white as jade, thin as paper, bright as a mirror, sound like a chime" of the four characteristics. These features are derived from the following characteristics of its ceramic craftsmanship:
Unique characteristics of porcelain
Gaochun Porcelain to the local neighborhood of porcelain stone and kaolin as the basic raw materials for porcelain, porcelain stone containing iron dioxide amount of iron dioxide generally about 0.6%, the amount of iron dioxide content in kaolin generally about 1%. Due to the past there is no more effective means of iron removal, and Fe, O, is a strong coloring agent, as long as the blanks contain 0.8% of iron trioxide is enough to make the formation of porcelain brownish-yellow color. In the reducing atmosphere of three iron oxide ferrous oxide, ferrous oxide at high temperatures and silicon dioxide to generate green ferrous silicate glass phase, so that the porcelain has a certain "white in the green" characteristics. Gaochun Chai kiln's special structure, but also decided to need to burn a thicker reduction atmosphere to ensure that the porcelain fired when the role of reduction. At present, Gaochun ceramics firing to the tunnel kiln, tunnel kiln and oil kiln, but whether it is a coal kiln or oil kiln, the control of the reduction atmosphere are generally thicker. Most of the tunnel kiln reduction atmosphere in the CO content is greater than 4%, some as high as 7% ~ 9%, in short, Gaochun Porcelain which is suitable for heavy reduction atmosphere and weak reduction atmosphere in order to burn out the traditional characteristics of porcelain.
Porcelain stone used by type
Due to the production, weathering and parent rock types of differences, different regions and even the same region of different mines produced porcelain stone, its chemical composition often has a big difference. Generally speaking, the iron content of 0.5% ~ 1% of this is suitable for the manufacture of fine white porcelain; 1% ~ 3% of this is suitable for the manufacture of celadon; 3% ~ 8% of this is suitable for the manufacture of black porcelain, potassium oxide, sodium oxide content of low for the production of tires; potassium oxide, sodium oxide content of high for the production of glaze.
Unique kiln structure and firing technology
Southern China's traditional ceramics can be divided into three categories: dragon kiln (tilting tunnel kiln), step kiln (tilting cold-bottomed multi-chamber kiln) and the town kiln (flat-flame kiln). Zhen kiln for the traditional kilns in China's unique style of kiln. Its firing chamber type is a big head and a small long oval, near the door of the kiln at the wide and high, near the chimney is gradually narrow and short, so there is a "duck egg kiln," the name of the whole length of about 15 m ~ 20 m, with a volume of 300 cubic meters ~ 400 cubic meters, is to pine firewood as fuel, long flame and less ash, because it does not contain sulfur or very little, which is suitable for burning reduction flame. This is suitable for burning reduction flame, for white porcelain, blue and white porcelain, color glaze porcelain and other traditional porcelain glaze coloring effect is good, can be mounted high fire, medium fire, low fire porcelain billet. Because the kiln cavity is relatively high (maximum height of not more than 6 meters), easy to mount the firing of large products, which is suitable for the conditions of multi-product production. Therefore, the kiln (also known as wood kiln in Jingdezhen) unit kilograms of porcelain fuel consumption is small. In addition, its structure is single, kiln construction speed, infrastructure costs less, large production, fast turnaround time, can be quickly fired and quickly cooled, which should be near Jingdezhen porcelain raw materials and porcelain characteristics of the traditional style. For some kilns in the south, in the control of firing atmosphere and porcelain quality, as well as fuel (pine firewood) consumption, etc., kilns are better than the dragon kiln, kilns and inverted flame kilns and other kilns.
Collaborative production according to process requirements
Gaochun Porcelain was founded in 1958, covers an area of about 720,000 square meters, now has about 1600 employees, mainly engaged in tea sets.
