The name of the restorer who talked to Chen Han was Chen Shuren, and he was one of the first batch of restoration technicians at the Jingzhou Cultural Relics Protection Center in Hubei Province.

He studied under Mr. Fang Beisong, an expert in the restoration of bamboo slips.

Since 2003, he has handled more than 100,000 bamboo slips, and it can be said that most of the bamboo slips unearthed are personally handled by him.

As for his teacher, it's even better.

At present, the dehydration technology and decolorization technology of bamboo slips used in China, and the cetyl alcohol protective solution used in the preservation of bamboo slips are all researched by Mr. Fang Beisong.

Now Huaxia's bamboo slip repair and protection technology can be so powerful, Mr. Fang Beisong has made great contributions.

In the bamboo slip repair piece, he is the authority!

And now the deputy director of the Jingzhou Cultural Protection Center is Mr. Fang Beisong.

After hearing Ronghua's introduction, Chen Han hurriedly stretched out his hand to shake Chen Shuren's hand, and asked very humbly: "Hello Mr. Chen, it's an honor to meet you." ”

"I don't know what you said about this device as an artifact for our archaeologists... What does that mean? ”

Chen Shuren didn't have the style of a simple restoration boss at all, just like an ordinary researcher, without any shelf, and laughed:

"This hyperspectral image analysis system can't be used, this is a spectral imager."

"It's complicated to explain exactly how it works."

"To put it simply, as long as the unearthed cultural relics are placed up, the original color of the cultural relics can be immediately displayed through the computer."

"This benefit alone is very convenient for you archaeologists!"

Chen Han nodded vigorously, his eyes shining at the machine, which was a bit like a large photocopier.

As long as you put the unearthed object on it and scan it, you can see the original color of this artifact from the computer?

This is indeed very time-saving and labor-saving for the restoration of cultural relics.

But for archaeologists, it's even more important!

Chen Han immediately understood why this machine was placed in the Jian Mu restoration room.

Because compared to other lacquerware, pottery, and bronze ware, it is obvious that bamboo slips need this machine the most.

Especially the slips excavated from the saturated environment!

In general, there are two types of excavated slips.

Bamboo slips excavated in a dry environment.

The saturated environment, that is, the simple slips soaked in the water when they were unearthed.

The first type of slips preserved in a dry environment were basically dried up and shrunk into the size of a toothpick due to water loss when they were unearthed, curled into a ball, and the text on them was not visible at all, and they needed to be treated with special technology to restore their shape.

Naturally, this kind of bamboo slip will not be able to use the spectral imager for a while.

But the second type of saturation is different!

Depending on the environment of the excavation, some of the water-saturated bamboo slips were buried in the silt, and some may have been soaked in the groundwater inside the coffin.

But no matter what the environment, this kind of saturated bamboo slip has not dried up and curled!

At least it looks very intact, but the actual bamboo fiber inside has been in a water-filled state for a long time, and it is very fragile, like soft noodles, which can be broken when touched exaggeratedly.

Moreover, after being unearthed, it will oxidize rapidly, and it will be as black as carbon, and the text will not be recognized.

After that, it has to go through more than 20 restoration processes.

It takes months or even years to clean, decolorize, dehydrate and other steps before the bamboo slips gradually become strong and return to their original appearance.

But with a spectral imager it's different!

Although there is no way to speed up the repair of bamboo slips, with the blessing of this equipment, even if it is oxidized, it only needs to clean the sludge on the surface and then put it on the equipment to scan it first.

Using the color of the bamboo itself and the different characteristics of the color of the ink, you can directly scan a "color photo", and the black text on the photo can be clearly displayed!

In this way, archaeologists can understand what is recorded in the bamboo slips more quickly, and can carry out excavation work more quickly!

Just like Chen Han's "Dispatch Book" found in tomb No. 168, as long as the text recorded on it can be scanned, then they can compare it with the burial goods excavated at this stage according to the number of burial goods recorded in it.

It's easy to see how much of it hasn't been cleaned up yet, and some things that you don't know what they're used for may be found in the text.

"Mr. Chen, most of the water-saturated bamboo slips we unearthed in Tomb M-168 are relatively clean, and there is not much silt and attachment on the surface of the Jane."

Chen Han's eyes lit up and asked, "Then can we use this device to quickly know the words recorded in the bamboo slips?" ”

Professor Li was also quite interested in turning around the spectral imager a few times, and said in amazement: "The development of science and technology is really very fast. ”

"Now it is possible to extract the text information of the bamboo slips before they are restored."

Chen Shuren smiled lightly and shook his head: "It's not as good as you think." ”

"If you want spectral imaging, you must be saturated with bamboo slips, and the simple surface must be completely free of silt, otherwise the image may be covered by silt."

"However, the bamboo slips you sent are indeed in good condition, there is less silt on the surface of the slips, and it is relatively easy to clean."

"If you act quickly, these more than 60 bamboo slips, we will work overtime, and we can clean them up in a few days."

Professor Li nodded understandingly: "Then I'll trouble you." ”

Seeing that they finished talking, Rong Hua, who had been standing quietly next to him, immediately answered: "Lao Li, you and Lao Chen should toss the handover of the bamboo slips by yourself." ”

"I took this student from Lao Kong to visit the workflow of the restoration of the slips."

Rong Hua put his hands behind his back and took Chen Han around the Jian Mu restoration room.

"That, classmate Chen Han, right?"

"Although archaeology and cultural preservation are not separated, it is still difficult for you who study archaeology to come into contact with the restoration of cultural relics in school."

"That, you should know roughly the repair process of bamboo slips, right?"

Facing the question of Ronghua Semi-Examination School, Chen Han hurriedly nodded: "You know, the big process is divided into three steps: cleaning, decolorization, and dehydration. ”

"The last repaired bamboo slips still need to be sealed with machine glass before the repair is completed."

Ronghua nodded with satisfaction.

"It's good to know, come, I'll show you the cleaning of the first part first."

Halfway through his words, as if he suddenly thought of something, Ronghua touched the pocket of his white coat, took out a mask and handed it to Chen Han.

"Mr. Chen, it is very rare for bamboo slips like the one you found in tomb M-168 to be in such a good state of preservation."

"In most cases, the excavated slips are often inseparable from the silt."

"You archaeologists know better than us how stinky thousands of years of silt is, right?"

Rong Hua's words immediately evoked a painful memory of Chen Han's internship in his junior year.

Buried in the ground and mixed with other organic matter for thousands of years, the stench is indeed reflux in the stomach.

In comparison, the taste of human excrement can be regarded as a small freshness.

Chen Han hurriedly took the mask and put it tightly on his face.

Although the mask can't completely resist the stench, at least it's better than facing the stench...

After putting on the mask, Chen Han followed Ronghua step by step and walked into a cubicle in the restoration room of the Jane Bamboo Slip.

As soon as he entered, he smelled a foul smell that he hadn't seen in a long time.

It smelled like a corpse + rotten eggs + socks worn by a male sports student for a day + sleeping in a student dormitory for three years, mixed with sweaty bamboo mats.

This smell easily broke through the mask and rushed straight into Chen Han's Tianling cover from his nose.

For a moment, he felt like he had lost his sense of smell.

In the cubicle, there were three or five restorers who were also wearing dust suits and masks, squatting next to several blue boxes that were one meter long, half a meter deep, and half a meter wide.

If the face does not change color, the bamboo slips that are inseparable from the silt are carefully peeled out of the silt little by little.

"These bamboo slips were discovered by the Jinan Archaeological Institute in Shandong Province when rescuing a Han tomb that was dug up by tomb thieves."

"When the local archaeological team arrived there, all the burial goods in the tomb were stolen."

"When these bamboo slips were found, they were all piled up in a corner of the tomb."

"Because of its age, it looks like a big lump of silt, and the archaeologists almost cleaned it up as silt."

"Fortunately, in the process of cleaning, a sharp-eyed archaeological team member found bamboo slips with handwriting exposed in the silt, so he didn't throw this treasure away as garbage."

"After identification, the people of the Jinan Archaeological Institute knew that this lump of silt was the most valuable cultural relic in this Han tomb, the Han Dynasty bamboo slip."

"It is estimated that when the tomb robbers robbed the tombs, they didn't have the heart to pay attention to this lump of mud, which allowed them to escape the thieves."

"However, for the tomb robbers, these bamboo slips are not very valuable, and it is not easy to get rid of them, it is estimated that even if the tomb robbers know that these are bamboo slips, they will not necessarily pay attention to them."

"But for us, these bamboo slips are the most valuable and precious cultural relics in this tomb!"
