Senior Sister Li Li was stunned halfway through her words!

Because the shelves in the restoration room are full of restored pottery utensils, at first glance, I thought it was a shop selling craft flower pots in the flower and bird market!

Senior Sister Li carefully picked up a restored pottery and carefully took a large amount of it, and said in surprise: "You didn't sleep all night last night and played the 'puzzle' by yourself all night, right?"

But it doesn't matter if you don't look at it, I was taken aback when I saw it!

There was no trace of shattering on the pottery she was holding casually, as if it was originally a complete vessel!

As the team leader of the archaeological workstation mainly responsible for the restoration of cultural relics, Li Li knows better than anyone that before today, there was not a single complete pottery in the cultural relics storage room of the workstation...... The complete cultural relics excavated were sent to the Panlong Cultural Heritage Museum, which had been built, as soon as possible!

Then so many complete utensils suddenly appeared, which means that they were all repaired by Er Yi himself overnight!

It's not too strange to repair utensils, and although the number of repairs is relatively large, it is a bit surprising, but the fragments themselves have been classified, and with the dexterity of Eryi's hands and his unscientific brain 3D modeling ability, the speed of splicing is not unacceptable.

To Li Li's surprise, there were no traces of restoration on these restored pottery, which was incredible, and with her experience in cultural relics restoration for several years, it was impossible to do this.

This is also why, on the pottery that the public sees in the museum, there are often unsightly white splicing lines, that is, the traces left by the "epoxy resin adhesive glue" used for restoration after solidification!

Moreover, after the pottery is broken, the edges of the fragments are often worn and mutilated, even if they are directly spliced together without glue, obvious cracks can be seen.

"How did you do that?"

"I mean, what do you glue the pieces with?"

Senior Sister Li said anxiously: "You can't use corrosive chemical glue to restore cultural relics!"

When archaeologists restore cultural relics, why do they choose resin glue that is easy to leave traces?

It is because some adhesives such as 502 cyanoacrylate, although the bonding speed is fast, colorless and transparent, the colloid is thin, and it is not easy to leave too large gaps, but there are corrosive to cultural relics, high temperature and high humidity are easy to degum, causing re-destruction.

"Senior sister, don't worry! I didn't use 502 instant adhesive glue!"

"I use a kind of 'biological protein glue' that I accidentally configured when I was doing experiments. ”

"Non-corrosive, insoluble in water, can withstand high temperature of 90~95 °C without melting, and has extremely high adhesion to pottery, porcelain, stone and wooden items, and no damage. ”

"I used resin glue to glue the pieces yesterday, and found that it would leave white marks, and I thought it was too ugly, so I asked Shu Xuemei to help me bring some over to try when I came over, but I didn't expect it to be very easy to use. ”

Er Yi smiled and pointed to the workbench, where he asked Shu Meizi to help him bring some things from the small laboratory yesterday: "This senior sister, you can take it for testing, theoretically it should be lower than the damage caused by resin glue to cultural relics, otherwise I wouldn't dare to use it casually, right?"

"If this 'biological protein glue' really has the effect you said, it will have too much effect on the restoration of cultural relics!"

Although Senior Sister Li was a little skeptical, she didn't want to talk nonsense, but worried and said: "Have you registered a patent? What if I take it for testing and leak the ingredients and formula?"

Professor Chen from the School of Chemistry and Molecular Sciences has already helped me apply for a patent registration, and it has been registered. ”

Er Yi smiled disappreciatively and said: "As for the formula or something, if others can detect it, I will lose!"

Doesn't that mean he loses?

This thing is not what he said about "biological protein glue" at all!

Rather, it is a kind of "alchemy binder" that he used [refining], [extraction], [synthesis] and [alchemy] to configure, which is specially used for some special alchemy experiments!

There is no special neutralizer, this "alchemy binder" is not sticky at all like water, and once it is stained and you want to break it, unless you use a special "alchemy dissolver", otherwise even if you break it, it is impossible to break it from the original trace.

If you want to crack the ingredients and recipe of this "alchemy binder", not to mention that no one should know [alchemy] in theory, you can't just inject arcane energy to catalyze the fusion of various material components!

The reason why Er Yi asked Shu Meizi to help him bring this thing over was to cover up the effect of [Sticky Technique].

However, the effect is not much different from what he said, and it is indeed extracted and synthesized from biological materials, which will not damage cultural relics.

"That's great!"

"Is it expensive to produce this glue?"

Senior Sister Li Li was pleasantly surprised to pick up the jar of "alchemy glue" brought by Er Yi and looked at it, obviously she also wanted to purchase a batch of them back for the restoration of cultural relics.

"The cost is not high, but it is too troublesome to configure, and there are no conditions for mass production at present. ”

The simplified version that Er Yi and Professor Chen configured together, although the effect is not as good as his alchemy glue, but it is definitely enough to restore cultural relics.

"And how did you manage to make it look like it didn't show any traces?"

Senior Sister Li Li studied for a long time, but she couldn't see what method was used to repair the pottery.

Er Yi didn't bother to explain, and directly demonstrated it to her.

All the fragments of a pottery were selected and soaked in a diluted pot of "alchemical dissolver".

Then you can see the soil and dirt on the debris quickly melt down, and then scoop it up and put it under clean water, dry it and repair it.

This is much more convenient than Senior Sister Li Li, who is afraid of damaging cultural relics, and carefully brushing with a small brush for half a day to clean up a piece!

Then he used a soft-tipped pen to absorb the alchemical binder solution and brushed it on the stubble of a fragment.

He used another soft-tipped pen filled with alchemy neutralizer solution to brush it on another fragment.

Align the two pieces together, "Click!" and stick it on, knock it on the table, clang, firmly!

As for repairing, it's even simpler, find a piece of discarded and useless pieces of the same material, mash it, grind it into the finest powder as much as possible, and then mix it into a cement with alchemy glue, smear it on the notch, and then use a sharp object to carve the same pattern as the surrounding lines, and use a neutralizer to spray it to set it!
