Old Harden, can you handle having your vision-shifting abilities on all the time?

The final step is surface treatment.

Xu Xing used special tools, including seven different grits of wet sandpaper ranging from coarse to fine, starting from 800 grit and gradually working up to 10000 grit, to polish the rivets and adhesive areas inside the bottle.

Every time you change to a new type of sandpaper, you must completely remove the scratches from the previous pass.

During the polishing process, Xu Xing continuously uses a microscope and X-ray vision to check, ensuring that the polished surface and the original glaze have a smooth transition without any steps.

By the time all the joints had been polished to be flush with the porcelain inside the bottle, it was already 10:30 p.m.

He activated his X-ray vision to perform a final check.

Looking through the glaze, he saw that the epoxy resin had completely cured, forming a dense bonding layer at the break.

The resin filling inside the punch is uniform, without any air bubbles or voids.

The new glaze layer and the old glaze layer form a good transition at the interface, and the microscopic crystal structure is continuous.

perfect.

From receiving the damaged device yesterday until now, it has taken less than forty hours in total.

This also includes a lot of testing and preparation work, and the actual repair time is only a dozen hours.

Normally, even an experienced master craftsman would need at least a week or even longer to prepare for the restoration of a B-grade porcelain piece.

After resting for a few minutes, Xu Xing used a special clamp to secure the entire bottle, put it in a shockproof box, locked it in a locker, and then went home.

……

The next morning, he organized the repair records, filled out the work order, and then rang the call bell for the assessment team.

Ten minutes later, the porcelain team also arrived one after another.

As soon as Liu Zhengang entered, he saw the complete gourd-shaped bottle on Xu Xing's workbench.

He paused for a moment, then quickly walked over.

"Is this the one you repaired?"

Liu Zhen's voice was full of disbelief.

Xu Xing nodded and said, "It took until after ten o'clock last night to get it done."

Liu Zhen put on gloves and carefully picked up the gourd bottle.

He first examined the glaze against the light; it was even, warm, and without any color difference.

Then, the surface was inspected under sidelight and found to be smooth and flat with no visible repair marks.

Finally, he lightly tapped the bottle with his finger, listening to the clear and continuous sound without any distortion.

"How is this possible..."

Liu Zhen murmured, "You only received this damaged piece the day before yesterday afternoon, and you repaired it in just one day? And it's even celadon glaze?"

Zhao Fang and Sun Hao also gathered around.

Zhao Fang is an expert in blue and white porcelain, but she also studies monochrome glazes.

She took the gourd-shaped bottle and immediately began using the professional tools.

If there is residual epoxy resin or glaze material in the repaired area under ultraviolet light, it will emit a different fluorescence than the original glaze.

However, Zhao Fang checked that the fluorescence reaction of each possible repair point was almost completely consistent.

"Seamless repair..."

Zhao Fang gasped in astonishment, exclaiming, "Xu Gong, how did you do this? How did you solve the color difference problem in the celadon glaze?"

Sun Hao was more direct. He took out his phone, opened a professional color difference detection app, and took pictures of different parts of the gourd-shaped bottle.

The app analyzes color data using algorithms and assigns a color difference value ΔE.

"The original part of the bottle has a ΔE of 0.5, the neck has a ΔE of 0.6, and the bottom has a ΔE of 0.35..."

Looking at the data on the screen, Sun Hao exclaimed in astonishment, "Wow! The color difference is all within ΔE 1.0, which is even higher than the restoration standards of many top museums!"

Chen Ming then entered the studio.

Seeing the three people gathered around Xu Xing's workstation, he frowned and asked, "What's wrong? What happened?"

"Team leader, look at this."

Liu Zhen handed over the gourd-shaped bottle and said in a complicated tone, "This is a Qianlong celadon gourd-shaped bottle repaired by Xu Gong."

Chen Ming's first reaction upon receiving the bottle was disbelief, but when he actually examined it, his years of professional experience told him that the restoration was perfect.

He spent ten minutes using all the testing equipment on the worktable, and finally had to admit a fact.

Xu Xing's restoration skills far exceeded his expectations, and even surpassed the level of the entire porcelain group.

Chen Ming put down the bottle, his attitude completely changed, and asked with respect, "From which master did you learn this skill?"

Xu Xing smiled and said, "I figured it out on my own. I just got used to it after working at the county museum for over twenty years."

No one believed him, but Xu Xing didn't want to say more, and they didn't feel comfortable asking any further questions.

Two minutes later, Zhou Wenyuan, the head of the assessment team, arrived.

After entering, he greeted Chen Ming first, and then his eyes were fixed on the gourd bottle on the worktable.

"Qianlong period official kiln celadon gourd-shaped vase".

Zhou Wenyuan put on his reading glasses but didn't start working immediately. Instead, he walked around the worktable first, observing the shape, glaze, and luster from different angles.

After observing for two minutes, he carefully picked up the bottle after putting on white gloves.

For the next twenty minutes, the studio was so quiet that only the sound of breathing could be heard.

Zhou Wenyuan's inspection process was textbook-perfect.

He first observed the whole under natural light, and then moved to a standard light source to examine every detail with a magnifying glass.

They then used a strong flashlight to examine the body of the porcelain, used an ultraviolet lamp to check for repair marks, and even used a portable X-ray fluorescence analyzer to detect the elemental composition of the glaze.

Finally, Zhou Wenyuan put down the gourd bottle, took off his reading glasses, rubbed his nose, and looked at Xu Xing.

"Xu Gong, did you repair this item by yourself? Without any assistance from others?"

Xu Xing answered frankly, "Yes, Professor Zhou, I did everything by myself, from receiving the damaged artifact to completing the restoration."

Zhou Wenyuan nodded, then looked at Chen Ming and asked, "Do you have records of the damaged artifact and photos of it before restoration?"

Yes, yes, yes!

Chen Ming quickly pulled up the system records and displayed the photos of the damaged artifact and its condition before repair on the big screen.

When they saw the three pieces of debris and the obvious finish line, the three members of the evaluation team exchanged glances and saw the shock in each other's eyes.

Zhou Wenyuan then asked, "The repair period?"

Xu Xing replied, "I received the damaged artifact yesterday afternoon, completed the repair at 10:30 pm last night, and finished organizing all the data this morning."

Zhou Wenyuan looked at Xu Xing again, his eyes filled with amazement: "In my forty years in this business, I've seen at least eighty or a hundred restorers."

But you're the first person to restore a celadon porcelain piece with three cracks and multiple fissures to this extent in less than forty hours.

Then, his expression turned serious, and he said, "This Qing Dynasty Qianlong celadon gourd-shaped vase was originally valued at 300,000 yuan, and the damaged piece is valued at 18,000 yuan. After being restored by Xu Gong, it meets the first-class restoration standard of the National 'Management Measures for the Qualification of Restoration of Movable Cultural Relics'."

"The company's internal restoration results were rated as excellent, specifically in that the accuracy of the restored shape was less than 0.3%, the glaze color was extremely high and the color difference ΔE was less than 1.0, and there were no obvious traces in the repaired area, achieving the highest requirement of restoring the old as it was."

"Based on a comprehensive assessment, the market value of this Qianlong celadon gourd-shaped vase after restoration is 90% of the original value, or 270,000 yuan."
