My system is not decent

In order to prevent the glaze water from sticking to the sagger, coarse mud kiln furniture is used to support the wares when firing porcelain.

At that time, the Yaozhou kiln used a three-legged firing frame, which would leave three indentations on the bottom of the porcelain.

And the method of stacking can save space, so it is inevitable to leave traces on the inner bottom of the utensils.

But the secret color porcelain unearthed in the underground palace of Famen Temple, the inner wall and outer bottom are as clean as a mirror, without any flaws.

This level of craftsmanship can only be achieved in the Shanglin Lake kiln.

In the end, a porcelain sagger was used and sealed with glaze to present us with the emerald green color of thousands of peaks.

If it is said that firing porcelain from saggers is a pioneering work in the history of porcelain making, then the method of sealing the seams of saggers with glaze is tantamount to icing on the cake.

At a temperature higher than the kiln temperature, a large number of iron ions in the porcelain body are reduced.

This may be one of the reasons why the secret color porcelain is of better quality!

Someone once tested and compared the composition of secret color porcelain and ordinary celadon.

The data shows that the reduced iron ions in the secret color porcelain are ten times that of ordinary celadon.

The high temperature in the completely enclosed space has created the emerald color of Qianfeng, and it was only a little bit blue-yellow glaze.

In the "clothes tent" found in the underground palace of Famen Temple, there are two blue and yellow bowls, which are more likely to be fired before the method of sealing the gaps of saggers with glaze water was invented.

At this time, Chen Wenzhe suddenly realized that the secret color porcelain has always been in a sagger, containing only one utensil.

The appearance of a secret color porcelain means the breaking of a sagger!

This kind of firing method is absolutely impossible to use overlapping firing.

It seems that this is the only way to keep the glaze smooth.

The more he looked down, the more Chen Wenzhe gained. Only then did he realize that the saggers made of secret-colored porcelain are also very particular.

Their mud is more delicate than ordinary kiln furniture.

The materials used for the sagger are still the same, but the mud of the secret-colored porcelain body is even more delicate than that of ordinary celadon, and even the composition has changed.

In addition, after the firing is completed, the sealed sagger must be broken to see the true appearance of the finished product.

As a result, the cost is much higher, which cannot be afforded by ordinary people.

Therefore, since the appearance of this kind of porcelain, it has been specially fired for nobles and royal families.

By this time, the main experience of this sagger has almost been read.

Sure enough, the last piece of porcelain was put into this sagger, sealed, and sent into the kiln.

Since then, it has been sealed in the kiln, until one day after a thousand years, it was washed by heavy rain and flowed out of the decayed kiln mouth.

Finally, after several twists and turns, he came to Chen Wenzhe.

This is a well-preserved celadon sagger, which has never been opened.

Therefore, the secret color porcelain that was put in back then is still there!

When seeing him, Chen Wenzhe was really amazed!

It's just that he can't describe it accurately in words, he can only say it's beautiful!

It can't be blamed that he is uneducated, but it has an indescribable beauty.

This is a lotus flower bowl, which consists of two parts: the bowl and the holder.

The bowl has a straight mouth and deep abdomen with ring feet, the cup holder is shaped like a bean, the mouth is turned outwards, the waist is tied, and the ring feet are turned outward.

The outer wall of the bowl body, the surface of the bowl tray and the ring foot are all decorated with double lotus flowers, which protrude like bas-reliefs.

The porcelain body is off-white, fine and dense, and the particles are uniform and pure.

The lotus bowl is glazed with green glaze, the glaze layer is thick and consistent throughout, and it is as smooth as jade.

Its shape is thick and dignified, its proportions are moderate, its lines are smooth, plump and gorgeous, and its whole body looks like a blooming lotus. It is ingenious in conception and natural.

Not to mention the craftsmanship, what is as thin as paper must have been achieved, and it must be as bright as a mirror. The most important thing is the precious light throughout its body. What is going on?

Having seen the pictures before, I only knew that the secret color porcelain was like water, ice, and fog, but after seeing it, Chen Wenzhe knew that the entire glazed surface was like a dream.

The emerald color of thousands of peaks, is it still green in the end?The green is not deep, but dazzling.

It was not fire, but a kind of precious light.

Is Baoguang like Yingying Qiushui?If it is said that the bottom of the porcelain is autumn water, what about the precious light on the surface of the porcelain?

Isn't this Bao Shao?Chen Wenzhe doubts that this is directly related to the Ru kiln wares made of gemstone porcelain in the Northern Song Dynasty.

Because of this luster, apart from seeing it on copper red glaze, it is only the porcelain fired with the precious firing technique that can achieve this effect.

Think about it carefully, in the previous production process of secret color porcelain, gem materials were added into it?

It seems to be, because of the addition of various ore powders, Chen Wenzhe couldn't tell what it was for a while, and besides, those natural minerals were really hard to tell if they didn't carefully distinguish them.

It's like a diamond, without processing, and its appearance after processing is simply incomparable.

"This thing must be related to Chai Kiln and Ru Kiln!"

Taking a last look at the small lotus flower bowl, Chen Wenzhe looked away.

Green as the sky, bright as a mirror, sound like a chime, and thin as paper, these adjectives were first used in the legendary firewood kiln.

However, seeing the secret color porcelain of Yue Kiln, Chen Wenzhe knew that it was not bad at all compared to Chai Kiln.

Besides, the last glory of Yue Kiln may overlap with the birth of Chai Kiln.

In the end, the Chai Kiln must have been inherited by the Northern Song Dynasty, that is to say, the Ru Kiln was also inherited from the Chai Kiln.

Legends and inferences all indirectly prove that the secret color porcelain, Chai Kiln, and Ru Kiln should be of the same origin.

Judging from the final fired fine porcelain, there must be some connection between the secret color porcelain and the rumored misty "chai kiln".

Although the existence of "chai kiln" is still a topic of endless debate, at least in the Ming Dynasty literature, "chai kiln" appeared more than once as the first of several famous kilns.

As for the name of "Chai Kiln", the common explanation is that Guo Rong, the emperor of the Later Zhou Dynasty, whose surname was Chai, should have liked the porcelain of a certain kiln, so he named the kiln after Chai to show his favor.

According to Zhang Yingwen's "Qing Mi Zang" in the Ming Dynasty, when discussing kiln wares, they must be Chai, Ru, Guan, Ge, and Ding.

In the mountains around Shanglin Lake, there are scattered pieces of porcelain from various ages. Some fragments of the Tang Dynasty whose age can be determined are already very thin, which is completely different from the thickness and stability of the early Yue kiln wares.

Judging from the bottoms of two stacked bowls that failed to fire and were excavated from the ruins, these fragments are more likely to come from ordinary kiln mouths.

Even so, the thickness of the wall is only three or four millimeters, which is enough to explain the problem.

This is still the case in folk kilns, so it is not a big problem for the secret-colored porcelain that is only used by the imperial court to reach a "thin" thickness.

Moreover, in the Five Dynasties, the porcelain making technology was more sophisticated than that in the Tang Dynasty.

The current general view is that during the period from Tang to Five Dynasties, there was no type of porcelain that could compete with Yue kiln secret color porcelain in terms of quality, shape and artistic achievement.

The "chai kiln" also represents the highest level of craftsmanship in this period, and the combination of the two determines the uniqueness of the "chai kiln" except for the secret color porcelain.

However, the prosperity is lonely after all.
