Chapter 1233 The Art of Fire

Traditional porcelain making in Jingzhen includes two techniques of firewood kiln firing and hand molding.

That is to say, there are two major lines of "burning" and "making" in the porcelain industry.

For the firing of porcelain, JDZ kiln workers have a common saying: "When one is full, burn second and turn off the fire three times".

It summarizes three aspects of firewood kiln firing techniques, namely, the kiln is full of code boxes, firing with firewood and extinguishing the fire at the right time.

Here is all experience, which needs to be accumulated in real production practice.

For example, every time a kiln is fired, there will be a unique ignition ceremony.

In front of the kiln, there are piles of split masson pine as fuel for firing porcelain, and the workers in charge of various processes are busy.

Their busyness is to meet the necessary conditions of "one full, two burning and three flame out".

The kiln must be filled first, and the kiln is filled with the saggers filled with porcelain blanks, which are moved into the kiln room and stacked in layers.

Because the blanks fired in the firewood kiln should be placed in a cylindrical sagger, and the saggers are piled up one by one.

And strength alone is not enough. It must be vertical from top to bottom. If the lower floor is slightly uneven, it is likely to collapse during firing of the kiln. That is not a little loss.

Therefore, full kiln is a technical job.

Therefore, Man Kiln is an independent business, and there are also special trade gangs, which are not accessible to ordinary people.

Of course, the most precious thing about firewood kilns is their difficult firing technology.

The master of the pile must have superb skills, and the ability to control the kiln fire is extremely high.

During the 30-hour firing process, you need to pay attention to when to heat up, when to keep warm, and when to add firewood.

During this process, the Zhuang master must be kept close at every step.

During this period, it is necessary to continuously add firewood and fire, and observe the temperature of the kiln at all times with "golden eyes".

Therefore, the firing of firewood kilns is extremely difficult, and the yield is also very low, only about 40%.

The distinctive feature of Jingzhen’s traditional porcelain-making firewood kiln is that it uses traditional porcelain kiln, uses original ecological wood fuel, and completely relies on the production experience and skills of laborers to master and manipulate the complex, what we modern people call Physical and chemical changes.

This kind of technology makes each clay tire become the most exquisite and beautiful porcelain after being fired at high temperature.

There is magic in the great contrast between simplicity, nature and complexity, science.

The finished products produced in this way are scarce, but extremely warm and moist.

The yield of firewood kiln is low, so it is very scarce.

This is impossible, because the calorific value of the firewood kiln is low, and the temperature gradient in the kiln is large.

The firing temperature of blue and white must be above 1300 degrees. If the temperature is too low, the green material will smudge, and if the temperature is too high, it will become gray and dark, which is very difficult to burn.

Therefore, it is very difficult to make firewood kilns, and they are very scarce.

However, Chai kiln porcelain is very moist.

Because the firewood kiln uses pine wood, pine oil will be produced when burning, and the pine oil will penetrate into the carcass to form a unique glaze.

The result of this is that it is as warm and moist as jade, and it is a "warm plaything" for a long time to play with.

And all these contacts are based on the craft of firewood kiln and watching fire.

The fire watcher, that is, the pile master, is very experienced.

If ordinary people want to gain enough experience, they will definitely need to explore and practice for a long time.

But Chen Wenzhe didn't need it, so he chose to make a breakthrough in the technology of kiln firing.

Being able to do this skill well should also drive all his skills to a big breakthrough.

Therefore, when he was learning how to make porcelain recently, he would not be left behind when he stepped into the kiln for firing at the last step.

Every time he had an immersive experience in his dream, he would be staring intently at the fire at the kiln door.

One by one, he will continue to add firewood to the kiln mouth.

And "watching the fire" is the most critical thing in the firewood kiln firing stage.

Generally, this kind of person is the chief engineer of firewood kiln firing.

It is because the master of the pile masters the firing of a kiln of porcelain.

Therefore, in the porcelain industry, making porcelain is very important, but firing porcelain is even more important.

Because no matter how well you make it in your hands, if you can't cook it well, it's useless.

Speaking of large-scale porcelain, it often takes several months, half a year, or even a year to make a piece of porcelain by hand.

When firing, it is often fired in the kiln several times.

And as long as there is a problem with one of them, this painstaking work that you have spent months making can only be discarded.

This is the importance of kiln firing technology, and until now, some people do not pay attention to this technology.

Chen Wenzhe had learned about the situation in Jingzhen, and found that it was a bit difficult for many pile masters to pass on this craft.

Up to now, this kind of craftsmanship can only rely on family inheritance.

This kind of inheritance from father to son and son to grandson has great flaws, but if you don't do this, it will be difficult to pass on.

Because firing a kiln is not just about watching the fire. This is really hard work, and most people are unwilling to do it.

Even some master masters are unwilling to do this kind of thing to their children and grandchildren.

Although it is a fire-making technique, the preparations are all sloppy.

Before lighting the fire, the saggers filled with porcelain to be fired should be stacked into the kiln one by one.

This is hard work, and if you are small, the physical exertion will be unbearable.

A sagger filled with porcelain is very heavy, and it takes a lot of effort to stack it to a high place.

In this way, the kiln union spends sixteen or seventeen hours a day in the kiln.

Building a kiln, installing a kiln, adding firewood, opening a kiln...

Every type of work needs to be done once, and only by calming down and insisting on firing firewood kilns can we achieve success in the end.

In general firewood kilns, the kiln is fired every three days, and theoretically, you can practice more than 100 times in front of the kiln every year.

After ten years as one day, we will finally learn excellent kiln firing technology.

Only by relying on more than ten hours of practical experience every day can we become a master of piles from a grassroots worker.

Dozens of manpower, hundreds of pieces of porcelain to be fired, and tens of thousands of catties of masson pine wood. This traditional kiln firing technology is costly, and the temperature is not easy to control, and the risk of firing is great.

When the kiln is full, if the saggers are not stacked properly, they will all collapse;

If the temperature is too high, the porcelain will melt in the sagger;
If the temperature is too low, the effect of the glaze cannot be fired.

When you were an apprentice, you saw the failure of the kiln every day. Could you not work hard?
Burning a firewood kiln is both physical and mental labor.

If you are helping others to burn a kiln, in case of failure, you have to consider the feelings of others.

At this time, you have to think about whether it is your own problem, or what aspect of the quality is wrong?

If the sagger is not good, contact the manufacturer.

If any aspect of the kiln has not been noticed, it is necessary to reflect on where the problem of the kiln lies.

Each time it takes 20-30 hours from ignition to firing.

The masters at other positions can work in shifts.

But as a stake master, you have to stay there all the time to ensure the stability of the fire temperature.

Therefore, the production of porcelain, "whether it is a creative shape or an exquisite pattern, cannot be separated from the last fire."

But this fire is in danger of being lost.
