"This is made of red clay, pure ancient river mud, clay formed by thousands of years of erosion and siltation. Several processes have been added in the middle, so it has the delicate feeling it has now!"
"That's right. The soil in your hometown is no worse than vermilion mud and purple sand!"
Chen Wenzhe shook his head directly: "There is still a gap. People's purple clay pots have been famous for a long time, but the clay in our hometown is still unknown?"
"Not to mention this, we have been preparing for the past two days. How are you preparing?"
"You mean Longquan kiln?"
"Yes, it's about repairing the remains of the Longquan kiln. It's very damaged. I looked at the photos and I can't even make out the shape. This time we need to cooperate with each other. Let's work together as a team, right?"
Looking at Chen Xingchen's expectant eyes, Chen Wenzhe couldn't refuse.
Let's cooperate. It's just repairs anyway.
"Everything that needs to be prepared is ready. It just depends on how things turn out."
Chen Wenzhe still had this bit of confidence, and he also glanced at the attribute list.
Blue and white: Qianlong blue and white (white ground blue and white master level 3, bean green ground blue and white master level 3, yellow ground blue and white master level 3, sky blue ground blue and white master level 3), Yuan dynasty blue and white (specialized level 2), Yongle blue and white (specialized level 2)
), Xuande blue and white (specialized level 2);
Dragon pattern painting and depiction (Master Level 3): Yunlong, Pearl Playing Dragon, Seawater Dragon, Chilong, Walking Dragon, Standing Dragon, Frontal Dragon, Sidelong Dragon, Kuilong...
Achievement points can be used to upgrade three master-level technologies, and there are five more independent inheritances. If a Qing Dynasty blue and white porcelain is completed, one more time can be added.
He currently only has six techniques for repairing Longquan kilns that cannot reach the master level, and the expert level is definitely enough.
After all, in today's society, people like Professor Tao can barely reach 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 engraving reaching the master level three, has also upgraded the engraving and color painting of the porcelain making process, both of which have also reached the master level.
Another thing is that the engraving process has become engraving, and the difference between the two is huge.
It used to be just carving, but now I can carve anything.
The porcelain making technology was definitely sufficient, but he was a little unsure about the supplementary work during repair, the hot joining process and the cold joining process.
This is called repair, but in fact it is no different from fraud. It is repaired and needs to be invisible to others.
And it is hard to say whether expert-level repair skills can make it look so fake that no one can see any flaws.
If that doesn't work, his 300 achievement points will be spent on these three skills.
Let’s wait until we get the fragments of the Longquan kiln and see how things go.
Which skill is suitable to be used at that time, which skill should be improved first.
With the decision made, Chen Wenzhe followed Chen Xingchen to his workbench.
Several more 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, which is still the top-quality Longquan kiln celadon.
If it is done well, it cannot be said that it will become famous in one fell swoop, but it will definitely occupy a place in the restoration market in the future.
Seeing everyone starting to get busy, even the chatty Chen Xingchen was practicing his follow-up, and naturally Chen Wenzhe was no exception.
He currently has two main tasks, one is to make a high-imitation blue and white porcelain from the official kiln of the Qing Dynasty, and the other is to repair the blue and white cloud-dragon pattern chi-ear vase in his hand.
No matter what he does, he needs to practice clay, so Chen Wenzhe directly took some porcelain clay and wanted to make some suitable tire clay.
However, he thought about it, took some kaolin clay, 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 kaolin was introduced into the porcelain body, the fire resistance of the porcelain body was improved, and it became very strong when fired.
This time he planned to make a large plate with blue and white clouds and dragon patterns, and the rest was used to repair the jar.
Of course, this method of incorporating kaolin is not Chen Wenzhe’s exclusive secret.
Because kaolin contains special minerals, it can be mixed into porcelain stone to make the body, which can increase the aluminum oxygen in the porcelain body, widen the firing range of the product, reduce deformation, and thus improve the yield.
Therefore, starting from the Yuan Dynasty, no matter what quality porcelain stone was used to make the body, Jingzhen potters had to add some kaolin.
The porcelain stone is mixed with kaolin to make the body, which reduces the glass phase in the porcelain body and increases the mullite, thereby improving the thermal stability of the porcelain.
In this way, the soft porcelain with low fire temperature (the firing temperature is about 1150 degrees plus or minus 20 degrees Celsius) gradually changes into the hard porcelain with high fire temperature.
There are many benefits to doing this. At least it will not deform easily after the tire is grown, and its shrinkage will also become much smaller.
Especially shrinkage is very important for repairing porcelain.
There is not much of a problem with the cold connection, but there is a problem with the hot connection.
Having said that, we must first talk about what is a cold connection and what is a hot connection.
For example, for cold jointing, the bottom of the newly fired porcelain is polished, and then the bottom of the old porcelain is polished to make it fit, and then glued and smeared to cover it up;
Hot welding is to draw the blank on the old base and fire it. Now this technology has become very exquisite.
Here, it is inevitable to use tire splicing technology.
The repair methods of porcelain include gluing pottery, curium pottery, filling gaps, installing handles, inlaying mouths, inlaying ears, inlaying bottoms, plugs, fitting hands, fitting legs, fitting base plates, decals, etc.
Many repairs inside require tire splicing.
The reason why ancient porcelain was spliced was mainly due to the limited production capacity at that time, or because the shape of the vessel was too large.
Hot splicing is much more difficult than splicing tires, but once it's done, unless you're an expert, you won't be able to spot any flaws.
During the period when the thermal bonding process first appeared, many experts could not see any problems.
It can be said that hot splicing was developed based on tire splicing technology. If you want to learn hot splicing, you must first learn to splice tires.
Porcelain splicing is an ancient manufacturing process, which involves dividing a piece of porcelain into two or three pieces and then assembling it into a complete piece.
It can be said that porcelain in any era must rely on the welding process. Without the welding process, there would be no complex shapes and colorful porcelain.
The welding of porcelain was inherited from the welding of pottery, which began in the Shang Dynasty.
It can be said that this technology has a long history!
