My system is not decent

Chapter 120
Chen Wenzhe already has the level of a master in receiving tires, whether it is horizontal or vertical.

The horizontal joint tire and the vertical joint tire should have been invented at the same time. If the horizontal joint tire cannot be made into porcelain, the vertical joint tire can be made?
Cold joining is relatively simple. A new piece of porcelain is fired as a whole, and the remaining old parts are connected to the new porcelain. After bonding, grinding, and trimming, it is completed.

However, doing so is easy for people to see, especially for some appraisers who specialize in looking for flaws, which can be seen almost at a glance.

But hot splicing is different. Hot splicing is really a difficult challenge.

He put the bottom and the newly made part together in a high-temperature kiln for refiring.

When you're done, totally be a whole!
This is not only a technical test, but also a huge test for the ceramic research of porcelain makers!

The so-called knowing what it is, also needs to know why it is.

Not only the shape must be perfectly matched, but also the style of the times, the painter, the shape of the utensil, and the glaze of the body are all perfect!

This is simply an impossible task, but the craftsmen of Jingzhen accomplished it a long time ago.

This is mainly a shrinkage problem. The part of the old porcelain is re-fired in the kiln, and the shrinkage is very small or even non-existent.

And the newly spliced ​​parts are fired in the kiln, and the shrinkage is not a little bit.

This is a problem, you have to worry about the shrinkage of the newly connected part.

Otherwise, the new part is the same as the old one. After firing, the new part shrinks, and the old part is directly crushed or broken, and it cannot be fired at all.

In fact, the problem is not limited to these, there is also the problem of new glazing.

The glaze will also shrink, so when the new part of the residual porcelain is fired, various problems will appear, and these need to be solved.

Some people have even applied for patents for such technology, which is mainly a method of reducing shrinkage during firing of green ceramic bodies.

Leaving aside the problem of shrinkage, just a repair involves splicing, complementing, hot splicing, and cold splicing.

It is relatively simple if cold joining is used to complete the completion. If hot joining is used, there are still several processes that need to be used, such as re-painting, re-glazing, and colored glazes are all faced with shrinkage ratio.

After digesting the existing inheritance, Chen Wenzhe found that the level of specialization is really nothing to the completion of crafting.

Although it can be done, it is definitely not perfect.

There is no other way, so I can only upgrade the two crafts of completion and hot connection. As for the cold connection, if you don’t need it, don’t upgrade it!

Chen Wenzhe chose to study after finishing the mud and waiting for it to dry.

Heat connection is more important, so improve the heat connection technology first.

Consume [-] achievement points and click to learn.

In an instant, a large number of heat-bonding process fragments appeared in his mind.

After being in a daze for a few minutes, Chen Wenzhe came back to his senses.

At this time, he was a little dumbfounded. Heat bonding involves splicing, completion, painting, and glazing, and one of them is to control the temperature so as to control the shrinkage ratio.

One of the most important problems is to control the shrinkage ratio.

However, if you want to control the shrinkage ratio, it is actually controlled by the temperature.

All he gets is experience, not skill.

It was difficult in ancient times to control the temperature perfectly, but it is easier for modern people because of the CNC gas kiln.

Maybe it's because painting and splicing are both master-level skills, plus the less important specialization in glazing, the knowledge he learned this time is really not much.

Since there are not many inheritances, Chen Wenzhe simply chose to digest them completely.

Chen Wenzhe sat in front of the workbench, seemingly contemplating, but actually his mind was trapped in a dream.

He is already very proficient in doing such things, and he is very adaptable to immersive learning.

So, he soon began to learn the heat welding process.

Heat transfer is considered a new skill. Looking at the scene in the dream, one should learn modern technology.

It's just that their level is really high.

At this time, Chen Wenzhe was immersed in the work of "bottoming", which is a common method of counterfeiting ancient ceramics.

In the dream, the master counterfeiter re-glued, glazed and fired the bottoms of bottles, bowls, and plates of famous kilns or official kilns. The porcelain bottom has changed suddenly and is worth tens of thousands of gold.

Especially after the use of CNC kilns, the "bottom-bottoming" technology has become a piece of cake for counterfeiters.

In the dream, Chen Wenzhe had just learned some techniques for controlling the CNC kiln, and fell into a dreamlike environment.

In the dream, he heard a news, a big news broke out in the Southern Antique Market.

A master of antique collection sold a Yongzheng enamel colorful jade pot and spring vase to a collector in Xiangjiang for [-] million yuan.

In the end, it was identified by Xiangjiang as the bottom of the Yongzheng official kiln bottle, followed by the spring bottle body of the enamel-colored lotus and jade pot. The Hong Kong authorities ordered the big collector to return [-] million yuan.

The big collector refused to accept it, and the Hong Kong side produced an appraisal certificate, and he obediently returned the huge sum of money.

What kind of appraisal certificate can make famous appraisers at home and abroad bow their heads?

This great collector is an expert in the TV National Treasure Lecture Hall, who lectures on Chinese ceramics of all dynasties. He is also the chief expert in the treasure appraisal columns of many TV stations at home and abroad for the past ten years.

Who issued the appraisal certificate to make him surrender?This is the number one news in the collection circle in the past two decades.

Those who do good things really have the ability to dig deep into the earth, and soon, the news spread.

The Yongzheng enamel bottomed jade pot and spring vase came from a master counterfeiter named Dashen in Jingzhen.

As early as the 80s, the master used the bowls and bottle bottoms of Nanhe Jun porcelain to recreate many Song and Yuan Jun porcelains.

Because the enamel of Jun kiln is thick and the bottom wall is also thick, it is not easy to crack when it is fired in an old-fashioned kiln. In addition, in the 90s, the digitally controlled gas (natural gas) kiln was born, which made the master even more powerful.

In front of the temperature-controllable kiln, he can manipulate the temperature as he likes, so that the connection between the old bottom and the new tire can be smoothly transitioned, and he no longer has to worry about the cracking of the new and old porcelain.

After the bottle body was finished, the great master handed over the floor plan of a spring vase with lotus enamel and colorful jade pots in Yongzheng, which was collected by Buckingham Palace in England, to an old painter of three generations in Jingzhen for drawing.

The painted enamel materials are also purchased at high prices in Jingzhen, an internal channel specializing in the supply of various glaze materials in the Qing Dynasty.

The money at the bottom of the jade pot spring bottle does not need to be faked, it is the official kiln money of Yongzheng.

If there is no money, it is a trivial matter in Jingzhen to solve this problem.

Masters who imitate official kiln inscriptions cost [-] to [-] yuan per character, which is comparable to the running fee of the most famous calligrapher in contemporary China.

The news that the Qing Yongzheng enamel colorful jade pot and spring vase had a new bottom and was sold at a high price and was returned soon spread to the ears of the great god.

When he heard the news, Dashen was toasting with friends from other places at the wine table.

At this time, more than half a catty of white wine had been drunk, and the burning of the wine and the bad news that the enamel had gone to Maicheng made the master very angry.
