My system is not decent

Chapter 1134 Behind any beauty, there are always unknown efforts
Construction of kilns and lamps began in the late Tang and Five Dynasties, and flourished in the Song and Yuan Dynasties.

Jianzhan is known as the "black peony" in porcelain. Under the trend of the times and aesthetics in the Song Dynasty, it was pushed to the supreme position.

At that time, from the princes and nobles to the traffickers and pawns, they all praised Jianzhan.

Jianzhan is proudly born with an iron body, and the unpredictable glaze color is outstanding. However, the firing of Jianzhan needs to go through a period of twists and turns.

From beneficiation to final firing, the hardships involved must be understood by craftsmen.

It is often said that there are 13 processes for firing Jianzhan, but in fact, when it is subdivided, there are more than 13 processes for firing Jianzhan.

And after completing these processes, will you definitely get a beautiful Jianzhan?

Not necessarily, because the beauty of Jianzhan depends entirely on the quality of the kiln.

As for kiln transformation, it really depends on luck, or in other words, on face!
Of course, Chen Wenzhe's firing of Jianzhan must rely on technology.

And this technology definitely did not come from him, but from Suihou Zhizhu.

After all, modern technology is not comparable to ancient times, and since the Song Dynasty, countless people have studied the firing of Jianzhan, so Chen Wenzhe can learn a lot of skills.

Therefore, even if he doesn't look at the money, but just looks at the technology, Chen Wenzhe can't let go of this kind of firing.

And it is not so easy to actually burn Jianzhan.

Fortunately, Chen Wenzhe was prepared when firing thin-bodied porcelain, eggshell pottery, and Liuxia lamps.

He had already placed an order in advance and bought suitable mineral materials from China.

It is impossible not to prepare early, because as long as it is high-quality porcelain, it needs specific and qualified raw materials.

Because the porcelain clay for firing Jianzhan is made of several different kinds of clay, the final result is generally high in iron content and dark red in color.

Using this kind of fetal soil, and then using a high temperature of more than 1300 degrees Celsius, the fired fetal bone is thick and hard, the fetal color is dark black, and there is a metallic sound when knocked, so it is called "iron tire".

This is the foundation. In fact, the firing of kilns and bowls depends on the kiln, because this is the real one color in the kiln, and all colors out of the kiln.

Behind any praiseworthy beauty, there are always unknown efforts, and the same is true for Jianzhan.

The traditional handicraft process of building a kiln and a lamp generally goes through thirteen processes.

This refers to the large process. According to the general process, there should be more than [-] types. If it is subdivided, it can be said to be [-] types.

Since you want to make Jianzhan, you must understand these.

However, before actually starting to make Jianzhan, one must first understand the shape of Jianzhan.

The shape of Jianzhan, regardless of its size, or its open mouth, skimming mouth, closing mouth, and beaming mouth, all have a natural lightness.

It integrates the historical traditions of the region, as well as the awareness of human relations and cultural mentality.

Such as a bowl with a beam mouth, open along the beam mouth, the abdomen is slightly arced, the abdomen is retracted, and the foot is shallow.

About 1-1.5 cm below the edge of the outer mouth, it is bundled inward to form a circle of shallow grooves.

The function of this is that when fighting tea, it can not only control the amount of tea soup, but also prevent the overflow of tea soup, so this groove is commonly known as "water injection line".

This type of bowl has a deep belly, a fuller overall shape, and a heavy hand feel.

Jianzhan has a unique shape, thin sides and thick bottom, thick and hard fetal bone, and has good heat preservation and heat insulation.

The traditional hand-made technical process of Jianzhan includes 42 processes including small processes.

It is difficult to form and fire by hand drawing, and it is fired under a specific temperature and atmosphere.

The crystalline artistic glaze produced by firing changes in the kiln has a low firing probability due to the unique firing process.

The glazing method of Jianzhan is a test of the kiln worker's true ability.

According to the records of "Tiangong Kaiwu", the person who makes the bowl needs to use his fingers to pick and hold the foot of the plain embryo to dip the glaze.

If you dip too little, it is not easy to get a good glaze color, and if you dip too much, it will easily stick to the sagger.

Therefore, it must be done exactly.

The shape of the Jianzhan is regular, the lines of the vessel are graceful and smooth, the feet are trimmed cleanly, and the inside of the ring feet is shallow and smooth, which gives people a sense of comfort like flowing clouds and flowing water.

The glaze layer of Jianzhan is thick, the glaze color is cyanotic, and the glaze generally reaches the glaze line. The phenomenon of glaze gathering is very common, and even the phenomenon of glaze dripping is often seen.

To sum up, the final firing effect of Jianzhan, not to mention the transformation of the kiln, must also achieve the effect of simple appearance, thick and simple, and smooth and simple shape.

The glaze layer is fine and hard, with a strong glass texture, which is the basic.

After achieving this effect, it will all depend on God's will.

Because the shape of the markings in Jianzhan is ever-changing, it is difficult to grasp artificially.

Others have a sense of three-dimensionality and layering, a sense of metal, and the color changes with the intensity of the light. They are also changing, and the strongest effect can be achieved, it all depends on God's will.

After sorting out everything and designing the first utensil to be made, Chen Wenzhe really started to make it.

He had already learned traditional craftsmanship before, and by doing so, he could only get some traditional Jianzhan.

As for what the final product looks like, it's just a matter of luck.

Therefore, if he wanted partridge spots, rabbit hair glaze, flare celestial eyes, etc., he could only continue to study in depth, and he had already found this part of knowledge, which was still the craftsmanship of some modern porcelain masters.

It's just that, to do anything, one must do it step by step, step by step.

Want to build a tall building without laying the foundation?how can that be?

Therefore, Chen Wenzhe once again entered the trial firing stage of porcelain firing.

At this stage, there is no need to pursue perfection, as long as a qualified Jianzhan can be fired.

And it is not so easy to make a qualified Jianzhan. As I said earlier, forty-two processes must be completed.

The first step is to take soil, also known as porcelain ore.

It can be said that for any kind of high-end porcelain, beneficiation is an essential process.

It can also be said that any characteristic porcelain will inevitably require special fetal soil ores. This is the true knowledge that has been practiced for thousands of years.

The traditional Jianzhan production is no exception, but its production process needs to be more meticulous. It is just a tire making, which needs to go through processes such as porcelain ore selection, crushing, aging, mud refining, and mud kneading.

This is the preparatory work for making the embryo, and then it needs to be drawn, trimmed and dried.

The last is biscuit firing. After firing once, the blanks need to be selected and washed.

Then it is glazed, dried, and glazed.

Finally, there are nearly [-] processes in kiln loading, roasting, cooling, and kiln exit.

Although there are modern machinery and equipment, many processes are still done by hand.

Among them, blank drawing is one of the traditional hand-made techniques that have been preserved to this day.

The production of Jianzhan is formed by hand-drawing, that is, with one hand, the pre-trained mud ball is placed on the rotating turntable, and the mud ball held by both hands is kneaded, pinched, pulled, pulled, Collect, release, etc., and flexibly draw it into a blank.

Don't look at it as a small cup with a big opening. It really needs some skills to pull the embryo.
