The old things I repaired have become fine

Chapter 253: A young man riding a white horse with a golden saddle, bends his bow and shoots a willow to attract a beautiful girl (asking for a guaranteed monthly ticket)
"what are you doing?"

A head suddenly popped up. Shen Le turned his head and sighed:

"Can you knock on the door before you come in next time?... I mean, some labs may be dust-free, and you need to wear special isolation clothing to come in..."

"Oh I know! But it's okay this time!"

The Alloy Boss came over happily. He shook his body quickly, and bronze hair appeared and disappeared on the side of his face, behind his head, and behind his shoulders.

Under the strong laboratory light, Shen Le could see clearly that there was no dust around him.

Yes, not at all. The big cat, or bear, was not covered in any dust, as if he had not rolled around in the yard and performed cat-style stretches in the open space before.

As he demonstrated, he proudly explained:

"I have great control! If I don't want to, not a speck of dust can get on me!

Don't worry, I've been in those laboratories before, I know the rules, those metallurgical experts often invite me over!"

I guess they must want to die when they see you stuffing all kinds of metal into your mouth. Shen Le rolled his eyes silently and decided to end the topic:
"I'm studying what this painting looked like so I can restore it accordingly. - I'd say this painting is in such a bad state. Are you paying attention to it?"

When this painting was unfolded, Shen Le felt really sorry for the painter.

The painting was broken and cracked all over, with many pieces missing. It was obvious that it had been roughly opened, put away, and hung more than once:

The painting is dark in color, covered with dust stains, and has a heavy musty smell. During the preservation process, no attention was paid to cleaning, and no consideration was given to humidity.

The silk texture of the painting is rotten and has become brittle. This... is caused by many reasons, not just one thing...

Gao Gan of the Ming Dynasty once said in "Eight Notes on Living":

"The ancient painting is old, the paper and silk are brittle, and it is not easy to roll it up and stretch it, so it is a little cramped. Even if it is damaged and broken, it is beyond repair. This is one of the lost works!

The servant boy did not know how to roll up the scroll, so he grabbed the scroll with his nails, not caring about the edges, and used the shaft to pull it tightly, causing the silk inside to break. This is the second lost technique!

Or it may be wetted by water leaking from the roof, rat teeth or cat urine, or it may become moldy or white due to the plum rain. It is not easy to wipe, so it may be rubbed with a coarse cloth and fall off piece by piece. This is the third lost piece!

Or if it is shown to laymen, who do not know how to look at it, they will hold the back of the painting with their hands and look at it as soon as they open their eyes, and the silk will fold;
Or if you hang a painting carelessly, it may fall to the ground and break. It cannot be repaired. Even if you repair it, what good will it do? This is the fourth lost art!"

Judging from the cracks, creases, mildew, peeling, and blurred colors on this painting, basically, except for not being bitten by mice or urinated on by cats, it has all the problems...

“Oh, I’m not a professional…”

Alloy Boss smiled a little embarrassedly:
"I later discovered that every time I opened it to look at it, it would be damaged a little bit, so I didn't dare to open it anymore! - So, it's been a hundred years since I opened it, right?"

"never mind……"

Shen Le was so angry that his throat was blocked and he was about to collapse. It hadn't been opened for a hundred years, so it might even grow mold and weeds!

The paint can even run to the back of the rolled-up painting!
You threw it down so hard, do you really cherish it?

But it's probably useless to talk to these monsters about cherishing antiques.

Just like the furniture in Shen Le's house, the original owner of the house might have just found a craftsman at the time and made a batch of them according to the popular craftsmanship at the time;
For Alloy Boss, this painting might just be a gift from his friend, an unknown work by an unknown painter at that time.

Although the value of ancient paintings has increased over time, when they look at these antiques, their value judgment probably still remains at the time when they first bought them...

"Forget it, I'll just tell you what I'm doing." Shen Le cut out picture after picture on the computer:
"To put it simply, I want to scan the elements in this painting to determine what it originally looked like. But this is too difficult, and it may take me a long time..."

Others have done Raman spectroscopy of single pigments, but there is not ready-made data for all types.

For example, for red pigments, Shen Le saw that his predecessors had made cinnabar, rouge, silver vermilion, vermilion fat, cinnabar, ochre, ochre powder, iron red, earth red, and western red. These ten pigments are difficult to distinguish with the naked eye.
As for green pigments, the different proportions of azurite, malachite, and azurite and malachite alone can be used to write a separate paper...

What about relying solely on microfocus fluorescence spectrometer?

If you think too much, it will tell you that there is mercury here, but it will not tell you whether it is cinnabar, silver vermilion, vermilion fat or cinnabar...

Shen Le is now in despair over the large number of spectral curves.

Damn it, the spectrometer is only responsible for providing the curve. Then, various methods such as data preprocessing, characteristic band selection, and normalized spectral index model are needed to obtain the results and make comparisons...

Shouldn't he leave professional matters to professionals?
"Why did you use this method to determine what the picture looks like?"

Alloy Boss looked at him strangely:
"I am the original owner of this painting! You can just ask me!"

Shen Le was refreshed. Indeed, the boss should have seen the original appearance of this picture, at least, he had seen what it looked like a hundred years ago.

Although I haven't watched it for a hundred years, the monster's memory should... maybe... possibly... be reliable, right?

He diligently spread out the drawing paper for the boss, put in place the four treasures of the study, and even brought out a batch of pigments - the traditional Chinese painting pigments that he had ordered when he decided to restore the ancient paintings.

After thinking for a moment, I turned on my computer again, connected it to my drawing tablet, and looked at him expectantly - Boss, please!

The Alloy Boss's fat cheeks twitched. He tentatively picked up a little paint, added water, blended it, picked up the brush, dipped it - Shen Le closed his eyes helplessly.

Boss, the way you hold the pen, I can tell you have never painted before!
"How about...we write a draft first?"

He offered the pencil attentively and asked carefully. The boss hesitated for a moment, replaced the brush with a pencil, carefully drew a few strokes on the paper, turned around a few times in a daze, and picked up the drawing board again:

"Can you bring out the previous photos so I can add the finishing touches on them?"

Shen Le no longer had any expectations for his drawing skills, but he still called up the picture and let him play with it.

The Alloy Master worked hard on the drawing board for a long time, but came up with a bunch of lines whose contents were indistinguishable. Shen Le observed carefully for a long time and shook his head helplessly:
"You are only at the level of an elementary school student in drawing, right?"

"…What! I'm not studying Chinese painting!"

The Alloy Boss was furious. He forced Shen Le to change a large piece of paper, spread it on the table, and began to try his luck:
Close your eyes, close your eyes, regulate your breathing, open your eyes. Suddenly, a cloud of paint powder flew up and landed on the paper.

First there was a batch of red pigments, which Shen Le recognized as mercury-containing pigments from the cinnabar and vermilion series;

Then there is another batch of red pigments, ochre, ochre powder, and iron-containing pigments of the iron powder series;
Then there are a batch of cyan pigments, azurite, malachite and other pigments containing alkaline copper carbonate...

Then, organic pigments, such as gamboge and carmine (another kind of carmine, not the mineral kind), were not used at all.

As a result, the whole picture is missing something, and the overall color is weird...

So controlling metals is your instinct, but when it comes to organic matter, you can't do it anymore, right?
Shen Le sighed deeply. It was amazing that the pattern drawn by simply relying on mental power to control the pigment was actually blurry. Could he see what the pattern would look like after the fluorescent scan?
Although the paint is incomplete, the pattern is damaged, and the overall color is off, it is basically possible to see what the painting originally looked like...

It is a very lovely picture. A young man riding a white horse with a golden saddle, reins in his horse from a distance, turns back, bends his bow and shoots at a willow.

The bow has been released, the arrow has been released, and the young man has not yet straightened his posture. In the distance, a willow branch falls, and a trace of cinnabar on the willow leaf is extremely eye-catching;
Under the willow tree, beside the stream, a young girl was supporting herself on the lush green grass, looking up at the willow branches.

Her expression showed surprise and joy. The artist captured the moment when her eyes were about to move away from the willow branches and look at the boy...

Further away, there were mountains upon mountains, clouds and mist rolling, and it seemed that red flags were flying between the mountains and a large group of horses were running towards them.

The arrangement of the mountains seemed a bit special. Shen Le always felt that it looked like an ancient map.

Shen Le smiled. Very good, he said to himself, I really want to restore this painting.

That's right, sir, those pigment powders you floated up are just pigments. No water or anything else was added, they just fell on the paper like that...

It won’t stick!
If I move the paper slightly, or blow on it, the pattern will change!

Shen Le was terrified, so he dragged the Alloy Boss aside and forced him to sit down. Then he dragged a stool and stood on it, taking pictures, taking pictures:
"Alas, it's a pity that I can't scan..."

"Why not?"

The Alloy Boss looked at him with an extremely strange look. Shen Le pointed at the powder speechlessly:

"What do you say?"

"Oh, are you afraid that the powder will escape? Leave it to me!"

The big man strode forward and held up the paper with both hands. He looked left and right:

"Where's the scanner?"

Big piles of powder stayed on the paper, neither moving nor sliding.

Very good, as a monster that broke in and as the owner of the item to be repaired, you at least fulfilled your obligations and provided enough information, right?

Although this information cannot be used directly for repair, there is still a lot of missing content, and it needs to be compared with the original image itself and the extracted information.

Shen Le printed out all the photos and scanned images, one in his left hand and one in his right hand, and fell into deep thought:

How and where can he find outside help to find someone to help him restore the painting to its original appearance?

Can I find a mentor?
Will he be beaten to death by his tutor for not doing his job properly?

　　It’s too difficult for cats… woooo woooo, it’s too difficult for cats
　　The cat searched for papers on ancient painting restoration, and then plunged into a bunch of inexplicable algorithms... He couldn't understand any of them, including the abstract and conclusion...

　　This is the most difficult time for the cat... The cat cries, the cat meows, the cat rolls over, the cat wants to be hugged...
