Mao Yuning knew the intangible cultural heritage burning blue engraving process, and the old professors were not surprised.

The intangible cultural heritage of burning blue chisels is niche, famous for its unique craftsmanship, and now there are many intangible cultural heritage engraved blue engraving craft jewelry on the market.

Mao Yuning turned his head and asked Dean Ge again, asking him if there were any cultural relics similar to those unearthed from the burnt blue chisel.

Dean Ge couldn't think about it, but it was still his assistant, and he reminded him on the side, only to remember that there was an ancient bracelet engraved with a burnt blue engraving, which was still hidden in the safe in the exhibition hall of the center of the museum, and he needed to pick it up in person.

When Dean Ge took the things, many people were a little untenable, muttering that it wasn't a problem of unlocking, and why did they talk about repair.

Feelings, a senior member of the M state base, can't open the lock, so he can only show off this bit of knowledge and not make himself too ugly?

Of course, the people who think this way are only auction houses and people who are engaged in the art industry.

Several professors in the museum, as well as several old professors who are master restorers, can see at this time that Mao Yuning is serious and serious, if she doesn't have some clues, she doesn't have to make things so complicated.

Dean Ge quickly went to the safe in the exhibition hall and took out the ancient bracelet engraved with a burnt blue engagement.

This bracelet was unearthed very recently, and the color glaze on it is very new, even if the bracelet is slightly deformed, it still does not affect its beauty.

Mao Yuning asked Dean Ge to put the bracelet on the tray and compare it with the box.

Two identical and similar processes, unearthed prediction of different years, color is also different, the process can also see subtle differences, the color glaze of the box is lighter, but the workmanship is more fine.

Several old professors of restoration, Dean Ge, including Professor of Cultural Relics, all looked at Mao Yuning, waiting for her words.

After Mao Yuning carefully observed the object, he said: "This ancient process, its color is formed by the chemical reaction of burning blue stone, rather than dyeing chemical materials, usually will not fade, but will lose its luster after long-term wear."

"Look at the dragon pattern of the box, this half is how fine the unrepaired color glaze is, and how complex the workmanship is."

Dean Ge and the others nodded their heads in agreement.

In the crowd, someone couldn't help but speak: "Can you tell me that the exquisiteness of the craftsmanship has anything to do with the purpose of your coming here today?" ”

His words are no longer subtle, and the subtext that anyone can hear is asking Mao Yuning if he can open the lock, and don't waste everyone's time if he can't open the lock.

Mao Yuning's mind just now was on the object, and when he heard this harsh voice, he looked up.

She was wearing a mask, her beautiful peach blossom eyes narrowed slightly, and her voice was clear and calm: "Hello, I know very well what I am doing here today."

“……”

Mao Yuning retracted his gaze, his gaze returned to the tray, his gloved fingertips gently fell on the ancient bracelet, and then crossed the dragon pattern on the small box, and finally dotted a little bright color, and the depiction traces added by several restoration professors, said: "When you repair, you didn't use the blue-burning process, did you?" ”

Several restoration professors nodded.

In the crowd, the person who had just been rebuffed by Mao Yuning spoke again: "Everyone knows that the blue-burning process needs to be at a high temperature of more than 800 degrees, and it can only be made after several high temperatures that it will not fade and the brightness is bright. ”

This box is so valuable, how can it be taken and reburned because of the repair of the shell.

Mao Yuning ignored him this time, didn't even look at him, just looked at a few restoration professors and said, "Is there any way to remove your raw material light industry?" ”

Dean Ge and several professors of the museum were instantly startled, they invited Mao Yuning to come over, they wanted to open the lock, go to the international exhibition hall, and show the real lock.

Why hasn't the lock been opened yet, but the shell that has been repaired with great difficulty has to be re-turned?

It's going to kill them.

A few restoration professors can hear what Mao Yuning meant, in order to protect the cultural relics, in the restoration, they also spent a lot of brains, these color glazes look bright, and their practical use is not chemical raw materials, and it is not troublesome to remove them.

As soon as they said it, they hurriedly asked people to get tools over.

Dean Ge hurriedly said, "This ...... It took everyone so long to complete the restoration, how can you say that it will be washed. ”

The lock can not be opened, and he can still take it to the exhibition, if it is really washed, and the lock cannot be opened, then he will definitely not be able to go.

The order has been issued from above, and this year, no matter what, it must be taken out and 'shown' in the international arena, otherwise no one can afford the consequences.

There was no need for Mao Yuning to speak, a few restoration professors, someone said: "Lao Ge, don't worry, it's a big deal, we will work overtime, and make up for it again." ”

"Yes, it was so laborious at the beginning, wasn't it inexperienced, and now it's not difficult to make up, but how to wash it off is difficult." Another master restorer professor chimed in.

Every artifact, from excavation to preservation, is very important, if not for the sake of integrity, the fewer traces left on the artifact, the better, the more reflects its unique sense of history.

The work of a restorer must be meticulous in order to achieve both, both to restore integrity and preserve historical traces.

Dean Ge: "......"

He looked at Mao Yuning with some incredulity, how did she do it, so that these old stubborns actually ...... Say something like overtime?

You must know that not long ago, when country Y came to borrow people, they all pretended to be sick, went on a collective strike, and sent their own representative students.

Mao Yuning couldn't hear Dean Ge's heart, but she knew that several restoration professors could hear her intentions.

After the raw materials are washed with special things, they return to their original appearance, and faint color marks can be faintly seen underneath, which is very light and light.

The restoration professor explained: "When it was unearthed, it was probably like this, we repaired these colors based on these faint background color traces, plus some historical data and cultural speculation. ”

Mao Yuning nodded, put the box back on the tray, and asked them to compare the three colors.

They are burnt blue engraved ancient bracelets, small box carved dragon patterns on the unrepaired burnt blue engraving, and just washed out of the light color traces.

"These light color traces, I don't think they are burned blue engravings." Mao Yuning looked at the others and spoke.

Several restoration professors had already guessed Mao Yuning's intentions, and nodded without much surprise, in fact, their suspicion at that time was that the raw materials used by the two were different.

It's just that the traces of color glaze here are already very faint, and they can only see them clearly with a magnifying glass, and there are almost none, and they can't make a specific identification at all.
