Jingdezhen's porcelain kiln

Speaking of the kiln as early as the Neolithic Age, China has invented a "cave kiln" used to Shaozao pottery. Shang and Zhou dynasties, there is a flame or a round-the kiln and kiln side, but at the time of porcelain and pottery kiln Shaozao with no special kiln, Shang and Zhou dynasties, like the original porcelain and pottery Hardware Yin Wen is the same kiln Fired. With the continuous development of the system Porcelain, kiln gradually separated from the Tao and become specialized Shaozao porcelain kiln.

According to form, there are kilns kilns steamed bread (round kiln), Long Yao, class kiln, gourd-shaped kiln, egg and other kiln. Steamed bread kiln and the Long Yao is the most common, and longer in use , North Plains to make more use of steamed bread kiln, and the mountains of the South, Mid-levels while the construction of the mountain Long Yao; on the following talk about these shapes of the furnace.

Steamed bread kiln, also known as "round kiln," and bore kiln fire room together for a steamed-shaped space, therefore its name. Steamed about kiln seen in the late Western Zhou Dynasty, has been adopted so far and it is popular in the north of the shapes of the ceramic kilns, Yao Men from the fire chamber, the furnace room, chimney, and other parts, living soil dug out to repair or Blank, built from brick. Steamed bread kiln is characterized by easy to control the speed of warming and cooling, moisturizing and good for roasting thick matrix, under high-temperature glaze porcelain larger viscosity; However, it is warming up, slower than the cool, firing a relatively long time, And before and after the kiln temperature, not evenly distributed from top to bottom, so defective that easy.

Long Yao, also known as a long kiln, according to the slope or tilt mound construction, and more in the long kiln 30 to 80 meters between the shape of the past, it is called Long Yao. Long Yao Yao Tou sub-structure, the kiln bed, the back-end of three parts. Long Yao seen in the Shang Dynasty, the era of both Long Yao Yin Wen firing pottery Hardware, and the original blue bake, known as the "co-fired ceramics kiln with" the late Eastern Han Dynasty to the end of the co-fired ceramics kiln with the Situation, there have been special porcelain firing of Long Yao. Since then, the gradual growth of Long Yao, North Korea and the inclination of the structure has been improved so that the results improve burnt Long Yao, Song and Yuan period, there has been a Long Yao kiln in the indoor multi-channel block masonry wall, its Is divided into several small rooms, located off the lower part of pyrotechnic firewall holes so that the room between the same room with, the so-called "sub-Long Yao room." Until today, some areas of the South is still in use Longyao firing ceramics. Long Yao of the characteristics of the building is convenient to put on a burn large, high-yield, the heating, cooling rapidly and easily restored to maintain an atmosphere suitable for roasting matrix thin, high temperature viscosity smaller lime glaze Blue and White Porcelain, so it was Long Yao said is the cradle of porcelain.

Ming-class kiln seen in the kiln of Jiande, Song and Yuan Dynasties from the sub-Long Yao developed from the room. It is based on materials such as brick according to tilt the slope of the building, the inclination of 21 degrees, Yao Men from the fire chamber, a number of rooms and chimneys, and so on, each room in turn connects to the next since the end of the formation of class levels, so Called "class kiln." It installed burn-Long Yao large, high-yield and easy to control or steamed bread kiln, the temperature at a speed of the advantages at the same time have the strength to save fuel, suitable for burning of German white porcelain kiln, and other components with high potassium, Viscosity under high-temperature glaze in large porcelain.
