Lao Yang reached out to connect the sky blue glaze in Chen Rui's hand, and even forgot the rules.

Then he started to check. If you want to talk about Lao Yang's inspection method, he is much more professional than Chen Rui.

In the past, Chen Rui looked at the authenticity of porcelain, which was very simple and crude, and he relied on his golden eyes.

Anyone with jewelry spirit must be a real guy.

If there isn't, it's definitely a fake, but if you ask him to tell why the porcelain is real and why it's fake.

But he couldn't say anything, but when he arrived at Lao Yang, it was a completely different story.

He first tapped the bottom of the plate with a flashlight, and then saw the translucency from above.

Then, at different light angles, look at the light reflected on the plate.

While watching, he also gave Chen Rui science popularization.

"This plate should be an old object because you look at the light reflected from the plate."

"Generally, new imitations will have a kind of incest that has not been tempered by time. In our verbs, it is called "Thief Light."

"It looks shiny at first glance..."

"And the old objects, after the baptism of time, have gone away all the fire, leaving behind a kind of warm light."

"The smoothness of this plate is very positive and has a very soft reflection."

After watching the reflection, the guy turned the plate over to look at the bottom.

However, when he saw the white circle in the middle of the plate, Lao Yang couldn't help but lock his eyebrows.

"What's going on?"

"Oh, don't worry about these first. Let's look at the ring foot of this plate..."

"If this plate was really produced during the Northern Song Dynasty, then the ring foot of this plate must be very rough."

"Not only will there be pores, but also grainy. This is also the most easily overlooked thing for modern counterfeiting molecules."

Lao Yang continued to teach Chen Rui's appraisal, and Chen Rui was also confused at this moment.

"Well? The plate made for the Royals will also have pores and particles at the bottom? Can that work?"

When Lao Yang heard what he said, he rolled his eyes.

"You really have to study hard."

"That was more than a thousand years ago, and it was when porcelain first started to become a pandemic..."

Chen Rui couldn't help asking again.

"Brother, didn't you say that porcelain was invented as early as the Han Dynasty? Why did it not start to be popular in the Song Dynasty?"

When Lao Yang heard his question, he couldn't help but reach out and knocked his head.

"Where have you seen the books these days?"

These days, Chen Rui often reads books on the identification of ancient porcelain.

He has indeed learned a lot of knowledge, but most of the books he read were books on the identification of porcelain in Ming and Qing dynasties.

I have read very few books on the history of porcelain development, after all, he has been in the industry for too short.

Knowledge accumulation always requires a process.

Seeing his question marks on his face, Old Yang shook his head and explained it to him.

"Actually, when it comes to firing porcelain, it has already begun during our Shang Dynasty..."

"Ah? So early?"

Chen Rui was shocked, and Lao Yang was full of pride at this moment.

"That's not, but our ancestors did not find the right soil at that time, so the burned pottery."

"But at that time, we were already inventing the technology of glazing when burning pottery."

"Later in the Han Dynasty, we finally found the right soil and mastered the technology of raising kiln temperature."

"Then the porcelain appeared, but at that time the burned porcelain was all rough, which could be used as plates and bowls."

"The porcelain was not on the table at this time, so the officials at that time did not pay attention to it."

"The tableware, sharp tools, and ornaments used by the princes and nobles at that time were mainly bronze and jade."

"Until the Tang Dynasty's social and economic development reached a peak, the Tang Dynasty's literati were pretending to be x."

"Just put effort into drinking tea cups and wine glasses, and then the porcelain making technology in the Tang Dynasty began to improve by leaps and bounds."

"A large number of tea cups and wine cups began to enter the sight of princes and nobles, and even Tang Sancai was used for burial."

"But the porcelain at that time was mainly domestic instruments, and it has not yet become ornamental instruments."

"Until the Northern Song Dynasty, because the Sixteen Prefectures of Yanyun were lost, the country lost the copper mines in the northern part of Jin Province."

"Bronze is very lacking, so Zhao Kuangyin began to order the large amount of porcelain fired."

"The official kiln was even specially established, and since then the porcelain began to truly enter the hall."

“Become an integral part of our daily life…”

After listening to this history, Chen Rui suddenly realized it.

"So, the official kiln porcelain firing began in the Northern Song Dynasty!"

"That's right, and although an official kiln was established at that time, the firing technology was actually being explored."

"For example, the screening of this porcelain clay cannot be as fine as it is now used for large-scale machining."

"No matter how you screen, there will inevitably be impurities in those mineral soils."

"So during the firing process, these impurities will burst, and the outside of the porcelain is glazed."

"In this way, the ring foot of the porcelain is the easiest place to exhale the air holes."

"So when we see real ancient porcelain, the bottom is often the easiest place to see the air holes."

"And because the mineral soil is uneven, it is also the most likely place to appear rough and uneven in the ring foot."

"If you compare porcelain from ancient official kilns with ordinary rice bowls in modern machined processing."

"You will even find that the bottom of the porcelain of ancient official kiln products is not as flat and delicate as that of the ordinary porcelain bowls that are machined by modern times."

Lao Yang pointed to this celadon and said to Chen Rui.

Chen Rui took the celadon, looked carefully, and reached out to touch it.

Indeed, you can feel the handle at the bottom of the celadon...

This feels really not as good as an ordinary porcelain bowl that you bought on the street for more than ten yuan.

But if you really talk about value, then the two will be in heaven and the other will be underground.

After all, the one in front of me is highly suspected to be Ru porcelain!

Lao Yang took the sky celadon from him and started playing with it in his hand.

"Well, from the glaze color, the opening and bottom foot, this piece of porcelain is right no matter how you look at it."

"But the bottom is white, what's going on?"

"If this is a real object, that stupid x, would you put this thing on the bottom of the porcelain?"

"Isn't this a bad baby?"

Lao Yang looked at the bottom of the porcelain and was puzzled.

But Chen Rui's mind flashed at this moment, and he suddenly remembered the set of Chinese porcelain he had obtained before.

At that time, in order to cover the Huairentang words at the bottom, a layer of material was pasted on the bottom and burned it again.

So will the cucumber at the bottom of this celadon be used for similar purposes?

Thinking of this, Chen Rui couldn't help but be excited.

He took the celadon plate from Lao Yang and began to study it.
