My system is not decent

Chapter 119 A Long History (300 Monthly Tickets Plus Updates)
"This is made of red clay, pure ancient river mud, clay formed by scouring and silting for thousands of years, and several processes have been added in the middle, so it has the delicate feeling it has now!"

"Not bad, the soil in your hometown is no worse than red clay and purple sand!"

Chen Wenzhe shook his head directly: "There is still a gap. The purple sand pot has been famous for a long time, but the soil in our hometown is still unknown?"

"Let's not talk about this, we have been preparing for these two days, how is your preparation going?"

"You mean Longquan Kiln?"

"Yes, it is to restore the remnants of the Longquan kiln. The remnants are very severe. I saw the photos, but I couldn't make up the shape. This time we need to cooperate with each other. Let's work together as a team?"

Looking at Chen Xingchen's expectant eyes, Chen Wenzhe couldn't refuse.

If you cooperate, cooperate, it's just a repair anyway.

"Everything that should be prepared is ready, it depends on how things are going."

Chen Wenzhe still has this confidence. By the way, he glanced at the list of attributes.

Chen Wenzhe: achievement points (334);
Independent inheritance: (6/11)

Tire splicing (vertical joint master level [-], horizontal joint master level [-]), repair (stitching master level [-], completion specialization level [-], hot joint specialization level [-], cold joint specialization level [-]);

Porcelain making: Clay master level [-], embryo drawing expertise level [-], embryo printing expertise level [-], embryo sharpening expertise level [-], carving master level [-], painting master level [-], glazing expertise level [-], kiln firing master level three.

Blue and white: Qianlong blue and white (the third level of white ground blue and white master, the third level of bean green blue and white master, the third level of yellow ground blue and white master, the third level of sky blue blue and white master), Yuan Dynasty blue and white (specialization level two), Yongle blue and white (specialization level two ), Xuande blue and white (specialization level two);
Dragon pattern painting and depiction (Master Level [-]): Yunlong, Playing Pearl Dragon, Seawater Dragon, Chilong, Walking Dragon, Standing Dragon, Frontal Dragon, Sidelong Dragon, Kuilong.
Achievement points can be upgraded to three master-level technologies, and there are five times of independent inheritance. If a Qing Dynasty blue and white porcelain is produced, one more time can be added.

He has only six techniques for repairing the Longquan kiln that cannot reach the master level, and the level of the professional level is definitely enough.

After all, in today's society, a level like Professor Tao's is barely reaching the master level.

Therefore, Chen Wenzhe, who has reached the expert level, is really not guilty.

The newly obtained inheritance, in addition to the dragon pattern, color painting, and depiction reaching the third level of master, has also upgraded the depiction and color painting of the porcelain making process, and these two have also reached the master level.

There is another one, the engraving process has become a depiction, and the difference between the two is quite large.

It used to be just engraving, but now it can describe anything.

The technology of making porcelain must be sufficient, but he is a little uncertain about the completion, hot-joint and cold-joint techniques in the restoration.

This is said to be repaired, but in fact it is no different from fraud. It is all repaired and needs to be invisible to others.

And it's really hard to say whether the expert-level restoration skills can achieve the real ones so that no one can see any flaws.

If it really doesn't work, his [-] achievement points will be spent on these three skills.

Wait until we get the fragments of the Longquan kiln and see the situation.

When the time comes, which skill is suitable for use, which skill should be improved first.

Having made a decision, Chen Wenzhe followed Chen Xingchen to his workbench.

A few senior seniors have been added here. They all went out for internships, but they didn't expect to come back this time.

Needless to say, it is definitely an opportunity to help the museum restore porcelain, or the top Longquan kiln celadon.

If it is done well, it cannot be said to become famous in one fell swoop, but it will definitely occupy a place in the restoration market in the future.

Seeing that everyone started to get busy, even Chen Xingchen, a chatterbox, was also practicing the bottom line, and Chen Wenzhe was no exception.

He now has two main tasks, one is to make a blue and white high imitation porcelain of the Qing Dynasty official kiln, and the other is to restore the blue and white cloud and dragon pattern Chi ear vase in his hand.

No matter what you do, you need to practice mud, so Chen Wenzhe directly took some porcelain clay, trying to get some suitable fetal mud.

However, after thinking about it, he took some kaolin and carefully mixed it into the porcelain clay according to a certain ratio.

The porcelain fired in this way will be harder.

If porcelain clay is used alone, the sintering temperature is low, and it is easy to collapse and deform during firing, and even cannot be made into porcelain alone.

After the introduction of kaolin into the porcelain body, the refractoriness of the porcelain body was improved, and it was very strong after being fired.

This time he is going to make a blue and white plate with cloud and dragon patterns, and the rest will be used to repair Chi ear bottles.

Of course, this method of mixing kaolin is not Chen Wenzhe's exclusive secret.

Because kaolin contains special minerals, mixed with porcelain stone to make the body, it can increase the alumina in the porcelain body, widen the firing range of the product, reduce deformation, and thus increase the yield of finished products.

Therefore, starting from the Yuan Dynasty, potters in Jingzhen needed to add part of kaolin no matter what quality porcelain stone they used to make tires.

Mixing kaolin in the porcelain stone will reduce the glass phase in the porcelain body, increase the mullite, and improve the thermal stability of the porcelain.

In this way, the soft porcelain with low fire (the firing temperature is about 1150 degrees plus or minus 20°C) gradually becomes hard porcelain with high fire.

There are so many benefits to doing this, at least it is not easy to deform after the tire is formed, and the shrinkage has become much smaller.

Especially shrinkage is too important for restoration of porcelain.

There is no big problem with cold connection, but there is a problem with hot connection.

Speaking of this, we must first talk about what is cold splicing and what is hot splicing.

For example, the cold bonding of the bottom is to polish the bottom of the newly fired porcelain, and then find the bottom of the old porcelain, polish it to make it match, and then glue it and smear it to cover up;

Heat-bonding means drawing and firing on the old bottom, and this technique is very exquisite now.

Here, it is inevitable to use the tire-connecting technology.

Porcelain repair methods include sticking pottery, curium pottery, filling vacancies, setting handles, setting mouths, setting ears, setting bottoms, plugs, matching hands, matching legs, matching bottom plates, decals and so on.

Many of the repairs in it require tire replacement.

The reason why the ancient porcelains were broken was mainly due to the limited production capacity at that time, or because the shape of the vessel was too large.

Hot bottom jointing is much more difficult than tire jointing, but as long as it is completed, if you are not an expert, you will not be able to see the flaws.

During the period when the hot bottoming process first appeared, there were many experts who could not see a problem.

It can be said that hot jointing is developed on the technology of tire jointing. If you want to learn hot jointing, you must first learn tire jointing.

Porcelain tire jointing is an ancient craft, which is to divide a piece of utensil into two or three parts, and then assemble it into a complete utensil.

It can be said that the porcelain of any era must rely on the tire bonding process. Without the tire bonding process, there will be no complicated shapes and colorful porcelain.

Porcelain was inherited from pottery, and pottery began in the Shang Dynasty.

It can be said that this technology has a long history!
