The history of coal-fired jun porcelain
Jun porcelain was first burned for firewood, and coal burning began to appear in the Jin Yuan period, and after the Yuan Dynasty, due to the depletion of shallow coal resources, deep mining was difficult, and firewood was used again. In the Ming Dynasty, due to continuous wars and serious shortage of resources, the kiln basically stopped burning.
Until the end of the Qing Dynasty, the firing of jun porcelain was gradually restored, when it was charcoal burning (lan charcoal, coal that was not burned through, less smoke and flammable).
In the 1950s, after the founding of New China, the firing process of jun porcelain was restored, and Ren Jian, a shenyuan jun porcelain artist, successfully used an inverted coal kiln to successfully burn jun porcelain, so far, the coal fired jun porcelain technology was restored, and the jun kiln technology was improved.
Artistic characteristics of coal-fired jun porcelain
1, the temperature is easier to control, because the combustion rate and heat of coal is higher than that of wood, so it is much easier to reach a temperature of 1300 degrees.
2, the flame of coal is short, relying on radiation heating, the flame is more difficult to control, so the effect of coal-fired jun porcelain kiln is relatively rich and dignified, strong and deep, masculine, artistic effect is more powerful, thick and stable.
3, the enamel of coal-fired jun porcelain is generally relatively rich, the jade texture is full, like jade is not jade like jade, like jade, like jade, lustrous and transparent, three-dimensional sense.
4. The grain of coal-fired jun porcelain is large and clear, the stronger the jade texture, the more obvious the opening effect, and the excellent viewing effect.
The complexity of coal-fired jun porcelain
Although the difficulty of burning jun porcelain is a little lower than that of firewood, but its complexity is very high, the product needs to be loaded with a bowl, the coal quality needs to be strictly controlled, the burning pool needs to be cleaned, each kiln ignition needs to be full of kiln, paving, blocking the kiln door, firing needs to add fire, pry fire, flat fire, cover the sky eye, cover the fire restoration and other complex processes.
The above is the content related to coal-fired jun porcelain, jun porcelain is the crystallization of the wisdom of the Working People in China, ancient Jun porcelain firing requires 72 processes, although the modern technology is more advanced, but the complexity of its process is still so, only in this way can we fire a good jun porcelain that is the unity of heaven and man.
