What does firewood kiln mean, how good is firewood kiln porcelain, and what are the characteristics?

The meaning of firewood kiln is as follows:

The firewood kiln is the imperial kiln of Chai Rong, the emperor of the Five Dynasties and Ten Kingdoms Zhou Shizong. According to records, the firewood kiln was founded in the early years of Zhou Xiande five generations later.

Cao Zhao of the Ming Dynasty wrote in the Hongwu period, and in the middle of the Ming Dynasty Wang Zuo supplemented the "Gegu Yao", which recorded: "The firewood kiln is out of the north, and the firewood Shizong burns it, so it is called the firewood kiln, the azure color is moist and charming, there are fine lines, and the loess is rare in modern times."

The porcelain produced by the firewood kiln is "as blue as the sky, bright as a mirror, thin as paper, sound like a chime, moist and delicate with fine lines." "Beautifully crafted and splendour, it was the best of all the kilns of the time.

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 renamed the firewood kiln from 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 the bottom is mostly coarse loess color.

Zhengzhou Xinmi Yuetai, formerly known as "Yangzitai", was the city of Zheng in the Spring and Autumn Period, where coal, aluminum, clay, limestone, jade and jadeite stone were abundant in the local area, and clay and jadeite stone were the best raw materials for firing Jun porcelain. Yuetai Village is close to the water of the Songshan branch, and there are large mulberry forests, which are good fuel for firing Jun porcelain. All this makes it a unique condition for firing Jun porcelain.

Since the Tang Dynasty, Jun porcelain has been fired here. In the Later Zhou Dynasty, Zhou Shizong Chai Rong established an official kiln group here that specialized in firing palace Jun porcelain supplies. When Chai Rong's younger brother Chai Gui was the defense envoy of Yuzhou, he handed over the platform to his jurisdiction, Chai Rong ordered Chai Gui to supervise the firing of Jun porcelain, and the kiln where Jun porcelain was fired was called "Jun porcelain firewood 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.

There are only feelings left in the firewood kiln, in fact, the difference between the effect of the firewood kiln and the gas kiln is very small. There are many factors that affect the quality of blue and white, such as the formula of blue and white materials, glaze water, fetal soil, etc., as well as the level of painting. Nowadays, with the advancement of science and technology and chemical industry, the gas kiln has long been able to make the effect of a firewood kiln, and players in the industry have also recognized the gas kiln.

The cost of the firewood kiln is high, but it is not high at the point, so the same 1000 a cup, the firewood kiln firing cost accounts for the majority, so you can only ask 300 a day of painters, and the gas kiln firing cost is low, so you can ask 500 a day of painters. The same 1000 cup firewood kiln painter can't be better than the gas kiln painter! Old players must choose a cup with a good painting, and what blue and white appreciates is artificial beauty.

Beginner players must say that firewood kiln, advanced players look at the comprehensive quality, and the top painters are all fired in the gas kiln, because the cost of trial and error in the firewood kiln is too high, and it is impossible to risk losing all the work just to add a little bit of score.

The difference between a firewood kiln and a gas kiln.

1. Bubbles: First of all, we can use a magnifying glass to look at the surface of porcelain, observe the bubbles, we can clearly and clearly see the difference between the bubbles on the surface of the firewood kiln and the gas kiln, the bubbles of the firewood kiln are uneven, because the firewood kiln must continue to add firewood in the firing process, so the temperature is high and low, uncontrollable, manifested in the bubbles is different sizes, there is a certain sense of hierarchy, the bubbles of the gas kiln are very uniform, the temperature can be well controlled during the firing process, and the size of the bubbles is uniform and dense.

2. Glazed blue and white: if there is no magnifying glass, you can also observe the blue and white on the glaze to distinguish, the firewood kiln is fired with pine wood as firewood, and the pine oil will be produced during the firing process, and the pine oil is adsorbed on the tire, and the glaze of the firewood kiln is moistened. The blue and white burned in the firewood kiln falls in the carcass, just like an ink painting, there is a feeling of smudging, on the other hand, the blue and white of the gas kiln is like floating on the surface, the decoration is relatively clear and neat, the firewood kiln needs to be fired for more than 50 hours, and the gas kiln needs more than 20 hours, so the texture of the firewood kiln fired for a long time will be more calm and warm than the gas kiln.

3. Color: 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 fused into the natural gray glaze after a long time of high temperature, and the color of the gas kiln will be white and bright.

What is the difference between diesel and gasoline, there must be a difference if you like this, because his quality is different, and the shelf life is different.

Your question, such a porcelain variety, the market value of genuine products is very high; However, there are many imitations on the market, so we must pay attention to distinguishing them, and the real ones must be well preserved!

Summary. Pro, and Ran kiln firewood kiln. The difference between a firewood kiln and an air kiln is that the ashes and flames directly enter the kiln, melt under the action of high temperatures, and combine with the porcelain carcass to form a work style with warm color, rich layers, and rough and powerful texture.

Compared with the gorgeous and bright glaze of the gas kiln, it embodies a simple, rich and clumsy beauty, which often gives people expectations and surprises, which is why people are obsessed with it and devote themselves to the pursuit of it. The firewood kiln is the art of fire and earth, and it is not controlled by humans when it enters the kiln, showing a random effect, and the characteristics of the firewood kiln are not so accurate, and there are often some unexpected wonderful effects. This is also the fascinating part of the firewood kiln.

The various processes of firewood kiln firing porcelain are completely based on experience, that is, now often said "ophthalmology", the test kiln temperature is generally to spit in the kiln, and then observe the evaporation rate of saliva to judge the kiln temperature, to know that the temperature difference of ten degrees will make the quality of porcelain change greatly, from the mining, processing, preparation of porcelain raw materials, to molding, glazing, firing, out of the kiln, there are various factors in each process will cause changes in the quality of finished porcelain, If the humidity in the air is too high, the water content of the green body will be too high and the thickness of the glaze layer will be affected, and the oxidation process will be affected during firing.

Pro, and Ran kiln firewood kiln. The difference between the firewood kiln and the gas kiln is that the ashes and flames directly enter the kiln, and the self-buried ashes melted under the action of high temperatures are combined with the porcelain carcass to form a work style with warm color, rich layers, and rough and powerful texture. Compared with the gorgeous and bright glaze of the gas kiln, it embodies a simple, rich and clumsy beauty, which often gives people expectations and surprises, which is why people are obsessed with it and devote themselves to the pursuit of it.

The firing temperature of the gas kiln can reach 1360 degrees, the temperature in the kiln is basically balanced, and the electronic temperature measurement and temperature measurement cone are used together to ensure that the kiln temperature is accurate, especially since the 90s, after 20 years of practice, whether it is the firing curve, or the glaze ratio has been very mature, Jingdezhen porcelain has undergone essential changes, basically can ensure the quality of various porcelain requirements, Chunchang whether it is fetal quality, glaze, color, etc. can meet the needs of consumers.
