The characteristics of firewood kiln porcelain, does firewood kiln porcelain survive

There is no surviving firewood kiln at present.

Due to the very small production of firewood kiln porcelain, and the thin porcelain, coupled with the war, the firewood kiln porcelain almost died out, and the firewood kiln porcelain has not yet been found.

The firewood kiln was burned in the early years of Zhou Xiande after five dynasties, from Zhengzhou, Henan Province at that time, during the five dynasties, Zhengzhou governed 7 counties such as Guancheng, Xinzheng and Xingyang. It was originally suitable for making pottery, and it was named because Sejong's surname was Chai at that time. At that time, it was also called the imperial kiln, and it was called a firewood kiln since the Song Dynasty.

Its porcelain is as blue as the sky, bright as a mirror, thin as paper, sound as chime, moisturizing and delicate with fine lines, and the fine color is different. It is the crown of the ancient kilns, but most of the bottom is coarse loess color.

<> firewood kiln porcelain does not exist at present.

Due to the very little production of firewood kiln porcelain, and it is thin porcelain, coupled with the war, resulting in the almost extinction of firewood kiln porcelain, there is no firewood kiln porcelain found at present, and we look forward to future archaeological discoveries.

Features of firewood kiln porcelain.

1. Scarcity: firewood kiln porcelain firing cost is high, the yield is low, and the number of firewood kilns existing in modern times is small, so it has scarcity. First, it is forbidden to burn firewood kilns, there is no pine firewood, if there is no special financial guarantee and purpose, no one dares to easily start the firewood kiln firing, the risk is high and the cost is high; the second is a kiln down, burning nearly 2,000 catties of pine firewood, the cost is quite high; The third is to burn a kiln to have a set of experienced team collective cooperation, the fire and temperature of the firewood kiln completely rely on manual control, especially the pile master, without decades of successful experience is not good, a slight negligence will appear "collapse kiln" accident, economic losses are often calculated in the tens of thousands of yuan; Fourth, the temperature of the front end of the kiln is high, the back end is low, and the middle temperature is the most moderate, so the quality of the porcelain fired in the same furnace is very different, and the yield is low.

2. Moisturizing: The use of pine fuel in the firewood kiln has a moisturizing effect on the ceramics, and the gas atmosphere in the kiln formed during the kiln firing process is very suitable for the raw materials of the porcelain fetus, which can fire the porcelain fetal effect of white and slightly blue, so that the ceramics have a unique style of white as jade. Wood kiln porcelain has traditionally been made of pine, pine is rich in pine resin, volatilized in the combustion process of pine resin has a moisturizing effect on ceramics, the principle of firing is to continuously add firewood to let the temperature rise slowly, so that the kiln utensils are slowly heated, plus the organic combination of water vapor in the furnace and porcelain glaze, so that the glaze of the fired porcelain is subtle and moisturizing.

Why didn't he survive and mislead people's children. In ancient times, there were no gas kilns, electric kilns, and coal kilns. All old porcelain is fired in a wood kiln.

The difference between porcelain in a firewood kiln and a gas kiln:

1.The porcelain carcass bubbles of firewood kilns and gas kilns are different.

Prepare a high-powered magnifying glass to look at the bubbles on the carcass. Because the firewood kiln has to continuously add firewood during the firing process, the temperature is high and low, uncontrollable, and is manifested in the bubbles that are different in size and have a certain sense of hierarchy. For gas kiln porcelain, the temperature can be well controlled during the firing process, and the size of the bubbles is uniform and dense.

2.The blue and white porcelain of the wood kiln and the gas kiln are different.

The blue and white burned in the wood kiln, the fired blue and white penetrate into the fetal bone, as if growing in porcelain, full of vitality. On the other hand, the blue and white of the gas kiln is like floating on the surface, and the decoration is relatively clear and neat. Of course, there are also people who use technical means, gas kilns or gas kilns and wood kilns to combine porcelain with uneven bubbles.

3.The color of the porcelain in the wood kiln and the gas kiln is different.

A more intuitive way to do this is to look at the color of the porcelain. When the firewood kiln is fired, the ash and flame produced by the burning of wood should be connected into the kiln, and the phenomenon of natural ash falling on the green body will be produced, and the natural ash glaze will be fused into the natural ash glaze after a long time of high temperature, and the color will be gray.

The characteristics of firewood kiln porcelain can be detailed from the scarcity and moistness, as follows:

1. Scarcity.

The firing cost of firewood kiln porcelain is high, the yield is low, and the number of firewood kilns existing in modern times is small, so it is scarce. After a kiln, nearly 2,000 catties of pine firewood were burned, and the cost was quite high. Burn a kiln to have a set of experienced team collective cooperation, the fire and temperature of the firewood kiln completely rely on manual control, especially the pile master, no decades of successful experience is not good, a little negligence will appear in the bucket with the "kiln collapse" accident, the economic loss is more serious.

The temperature at the front end of the kiln is high, the back end is low, and the middle temperature is the most moderate, so the quality of the porcelain fired in the same furnace is very different, and the yield is low.

2. Moisturization.

The use of pine fuel in the wood kiln has a moisturizing effect on the ceramics, and the gas atmosphere in the kiln formed during the kiln firing process is very suitable for the raw materials of the porcelain fetus, which can fire the porcelain fetal effect of white and slightly blue, so that the ceramics have a unique style of white as jade.

Wood kiln porcelain has traditionally been made of pine, pine is rich in pine resin, volatilized in the combustion process of pine resin has a moisturizing effect on ceramics, the principle of firing is to continuously add firewood to let the temperature rise slowly, so that the kiln utensils are slowly heated, plus the organic combination of water vapor in the furnace and porcelain glaze, so that the glaze of the fired porcelain is subtle and moisturizing.

Identification method of firewood kiln porcelain

1. Look at the surface bubbles: identify the surface bubbles of the firewood kiln porcelain, because the firewood kiln porcelain needs to be continuously added in the firing process, because the temperature will be high and low, this situation will lead to the formation of bubbles of different sizes on the surface of the firewood kiln porcelain, and the bubbles have a certain sense of hierarchy.

2. Look at the color: In addition, you can also look at the color of the firewood kiln porcelain, the ashes and flames produced by the burning of the firewood will enter the kiln, and the porcelain embryo will have a natural ash phenomenon, and it will be fused into a natural Qiao gray glaze after a long time of high temperature, and the color will be grayish.
