The production process of any kind of porcelain is not simple.
In particular, some official kiln porcelains are made with great care.
Therefore, modern people can sum up only eight processes, but in ancient times, when excellence was pursued regardless of cost, seventy-two processes were required.
This is the difference, and this is also an important reason why modern crafts are always less successful than ancient crafts.
It's not that they can't do it, but they don't want to do it in order to maximize costs.
However, good porcelain often requires excellence.
For example, sculptures, in addition to molds, also require carving, sculpture, hand-kneading, etc., which all require increased costs.
This is not the case during the firing process of modern Jun porcelain.
On the basis of inheriting the tradition, modern Jun porcelain has carried out bold reforms, added modern popular elements, and most importantly, saved costs.
Whether processing or modeling, everything becomes simple.
Today, with the rapid development of society, the progress of the times marks the improvement of technology, and also means that more and better Junci art works will be born, adding new colors to Junci!
After researching it, Chen Wenzhe still found that according to the technological progress in recent decades, it is the easiest to re-fire Jun kiln step by step.
There is no way, this is the experience of previous generations.
It is naturally the smoothest to follow the experience of predecessors.
In the 1950s, small bellows-type kilns were used for firing, called furnace jun.
The firing raw material used is blue charcoal. Because this is a relatively traditional firing process, the yield of this firing process is relatively low.
Although the yield is extremely low, the fired effect is relatively simple and its color and texture are relatively unique.
The coal-fired technology from the 1970s to the 1980s was produced by Junmei Factory No. 1, Junmei Factory No. 2, state-owned porcelain factory and Shenge Dongfeng Porcelain Factory.

The kiln shape of the vessel is extremely rich, and there is no mark on the bottom.
In the 1990s, Jun Porcelain's gas kiln firing process was born, and various Jun Porcelain kiln entrances began to fire gas kiln works.
Because of the special firing environment of the gas kiln, Jun porcelain has broken through its bottleneck and produced many fine products.
The Jun porcelain tire materials of this era were divided into fragrant gray tires and gray and white tires.
Most of the deposits are made at the entrance of the kiln, or the author's own name is used as the deposit, and there are also stamped ones and hand-signed ones.
I believe that what everyone likes the most is the works of masters, but works of masters with collectible value also require collectors to have unique vision. It is difficult to encounter works with real collectible value.
Different masters' work styles, firing techniques, and academic achievements will have a direct impact on the collection value of the works.
Jun porcelain, apart from the good things produced by masters, the most important thing is that it requires surprise.
If the kiln changes, it still depends on the face.
For example, now, there is a story related to Jun porcelain.
The prototype of this story is about the treasure "Panlong Bottle" at the entrance of a certain Jun porcelain kiln.
After it was fired, I was going to smash it, but later I was offered no money to sell it, and it was also visited by many CCTV programs.
In fact, this treasure of the museum was almost smashed due to flaws when it first came out of the kiln.
Because this treasure of the exhibition hall is a defective product in a strict sense.
The kiln mouth of Jun kiln is usually smashed directly when defective products are encountered during the operation of the kiln to prevent the defective products from flowing out to the market.
A perfect Jun porcelain work must first be dignified and elegant in shape, and the glaze must be smooth and clean without any defects.
However, we must distinguish these defects from defects and minor defects, because the focus of Jun porcelain lies in the kiln changes.
It is difficult to find identical works, so many collectors are more tolerant of the firing of Jun porcelain.
This Panlong vase is very beautiful. It is a dark carmine red color with red rabbit threads wrapped around it all over the body of the Panlong vase.
However, it has a fatal flaw, which is the defective problem mentioned at the beginning.
There are several bulging bubbles on the body of the Panlong bottle.
In fact, if the bubble is under the glaze and does not protrude, the glaze bubble will not burst. This is a normal phenomenon.
But by chance, this glaze bubble happened to appear on the surface of the glaze, and it had an obvious sense of abruptness.
According to the Jun porcelain inspection standards, such a product should be smashed and thrown directly into the kiln soul pond.
Several kiln workers were very sorry to see it. When they were about to throw it aside, there was a customer from Shendu nearby who took a fancy to this Panlong bottle.
He said that several bubbles were very unique, and they happened to be on the body of Panlong, which looked like a newborn baby dragon.
Several kiln workers came up and took a look, and they really looked a bit alike.
Coupled with the position of the bubbles and just a few hints of carmine red, it looks more vivid.
In this way, the Panlong bottle was preserved.
Because of its defectiveness, the artistic value of this work has been greatly increased.
Because of its defectiveness, it has become a unique item.
This is the real kiln transformation. After entering the kiln, no one can guarantee what the final product will be like.
And often things that are accidentally fired cannot be copied and become even more precious.
However, in the final analysis, these are still the use of copper red glaze.
The reason why Jun Kiln became famous was largely due to accidents.
Accidents, that is, kiln changes, situations like this are common in Jun porcelain.
We all know that the main contribution of Jun porcelain is to fire it into the gorgeous red glaze Jun porcelain.
It was also because of the copper red glaze that it pioneered the copper red glaze.
Because it has changed the previous situation where my country's high-temperature color glazes only had black glaze and celadon glaze, and opened up a new artistic realm.
When it comes to the characteristics of Jun kiln, the biggest feature is actually the glaze.
The craftsmanship of Jun kiln is different from other famous kilns in that it is opacified glaze, an opaque glaze.
Guan kiln, Ge kiln, and Ru kiln all have transparent glass glazes, and the glaze is translucent;
Jun kiln is not a glass glaze, but an opacified glaze.
The advantage of opacifying glaze is that it has strong covering power and can completely cover the fetal soil.
This is an advantage, but it also leads to a disadvantage, that is, Jun kiln does not have high requirements for the tire, and loose or rough tires can be covered by the glaze.
This phenomenon can be clearly seen in the Jun kiln of the folk kiln.
These shortcomings have now become the characteristics of Jun kiln identification.
If Chen Wenzhe wants good kiln changes, he must naturally control the kiln changes, which requires extremely high technology and, most importantly, experience.
Jun kiln porcelain belongs to the kiln-changing system. Theoretically, its color cannot be controlled before entering the kiln.
The ancients praised Jun kiln like this: "The purple green suddenly turns into mist at sunset", which means that the color suddenly changes.
The so-called "kiln changes" refer to changes that occur during firing after entering the kiln, and are beyond human control.
As the saying goes, "One color enters the kiln, and many colors emerge from the kiln." This is the essence of Jun kiln.
It is absolutely impossible to control the Jun kiln in the early stages of firing.
However, after a long period of exploration by the craftsmen, they were gradually able to control it within a certain limit.
