The importance of cultural relics is self-evident. They are relics of human culture, material wealth created by ancestors throughout the ages, and precious heritage with historical, artistic and scientific value. However, due to various reasons, cultural relics will be damaged by nature and man-made. In fact, almost all cultural relics must be restored on a large scale after being unearthed. The dazzling cultural relics we see in the museum are restored to their original appearance after restoration by cultural relics protection and restoration workers. The heavyweight national treasures such as Simuwu tripod, the Changxin Palace Lantern of the Western Han Dynasty, and the flying swallow are all the same. The country has never stopped restoring the restoration of the Terracotta Warriors and Horses of the Mausoleum of Qin Shihuang.

Our country's traditional cultural relics restoration technology has always been in the world's leading position. In this field, we are constantly creating miracles. When the treasure of the Shanghai Museum's temple was unearthed in 1988, it was just a pile of broken tiles with a number of up to 40 or 50 pieces. After three months of restoration, it was re-formed and estimated at tens of millions. The golden jade robes from the tomb of Liu Wu, the king of Han and Chu, Shanxi, Xuzhou lion, was unearthed in 1995, and it only took several years to complete the final restoration.

Tang Feng's current repair ability is simply not comparable to these repair masters who create miracles. Not to mention his own repair skills and experience, a complete set of repair equipment alone is not something Tang Feng can meet with his current financial resources. Of course, compared with those time-consuming and labor-consuming complex repairs, the repair of this plum green brush is much easier, and Tang Feng is fully qualified.

The restoration of plum green cyan porcelain is divided into several steps: cleaning, bonding, filling, basement, coloring, and glaze. The traces of the bottom of the plum green pen are relatively new. There is no stain infiltrate. There is no need to use professional equipment such as ultrasonic cleaners. Use a cotton swab dipped in chlorine-containing disinfectant to wipe the knocking mouth to complete the cleaning. After the cleaning is completed, the formal repair must be dried with infrared heating equipment. Tang Feng, who does not meet the conditions, can only settle for the second best. He brought the hair dryer for Lin Muyu to blow his hair, and used the hot air of the hair dryer to speed up the evaporation of the disinfectant water.

This brush wash is just a knock, which is a slight damage and does not require large-scale filling and foundation. Just replenish the defective porcelain body. The characteristic of plum green celadon is that its body is thin and thick glaze is relatively low. Tang Feng first pours out a small amount of high-end porcelain powder, then adds colorless and transparent epoxy resin for stirring, and finally makes the filling putty that must be used to repair porcelain. This matter is complicated, but in fact it is similar to the principle of painting walls in interior decoration, but the raw materials are used.

The porcelain body washed with this pen was only a little defect. Tang Feng replenished the porcelain body with only a small amount of filling putty. After that, he used a hair dryer to accelerate the curing of the porcelain powder putty. After drying, the subsequent repair cannot be carried out immediately. It is necessary to wait for the chemical effect of filling putty to stop completely. Tang Feng clapped his hands and looked at Lin Muyu who was holding his cheeks and watching him work. Lin Muyu asked Tang Feng: "Did I affect you?"

"How could that happen?" Tang Feng smiled slightly and said, "Mu Yu is by his side and is the greatest support for me."

Lin Muyu smiled and said, "Tang Feng, you have learned to lie, and your face will not blush when you say such words."

Tang Feng said: "To be honest, why do I blush and my heart beat faster?"

"I won't talk to you about this." Lin Muyu looked at the Mei Zi Qingbi and asked Tang Feng, "Can you see it after it is repaired?"

Tang Feng said: "After all, the repair is just a man-made post-processing. The repaired antiques are not as good as the original device without defects. If you meet an expert, you can still see it carefully, but the original intention of the repair is not to deceive people, but to restore the overall beauty. Even if the repair is perfect, the auction house will still inform the customer when the goods are exhibited, otherwise it will be a fraud."

Lin Muyu asked, "Then why do you need to repair it? Just sell the damaged original device to the other party."

Tang Feng said: "For buyers, seeing the repaired antiques is completely different from seeing damaged antiques. I just want to improve the competitiveness of this pen washing through my own repair in exchange for a more ideal price, because I am confident that I can repair the pen washing to the most perfect level." The so-called most perfect level means that the pen washing has been repaired, but the buyer cannot find any traces of the repair for a while. If it weren't for fear of implicating Zhuji Auction House, Tang Feng was simply planning to conceal the fact that he had repaired this pen washing, so his grandfather sold a repaired Jianyao black cup to the Japanese. This time, because he urgently needed money, and when encountering such things that need to be repaired in the future, Tang Feng would not be planning to entrust it to the auction house. It would be bad to cheat people, but he could cheat people.

After a while, the porcelain powder putty was completely solidified, Tang Feng continued his work, and the background color repair was done after the porcelain body was repaired. Celadon is a monochrome porcelain, and it is relatively easy to color. At least it does not need to be like blue and white or colored porcelain, and the color paintings must be drawn. The color must be adjusted with nitro paint first to make the same color as the original. Color adjustment is also the most critical step in repairing celadon. The color cannot be contrasted at all. Tang Feng debugged it on the palette many times before turning out the green green that is most suitable for plum green. He applied a little on the brush and washed the surface without any defects. After the nitro paint was naturally air-dried, he asked Lin Muyu and said, "Muyu, do you think this color is suitable?"

Lin Muyu took a magnifying glass and carefully observed the color difference between the nitro lacquer and the original instrument, and said, "The color is darker."

Tang Feng first used transparent imitation glaze paint to repeatedly apply the green nitro paint on the green nitro paint. After the imitation glaze paint was completely air-dried, he sprayed a thin layer of nitro varnish with a spray gun. After a while, he asked Lin Muyu, "What about now?"

"Yeah." Lin Muyu nodded and said, "I can't see it now." The coloring cannot be directly compared with the color of the original device itself, and the color difference after glaze is also taken into account. Then, Tang Feng dipped a brush in green to start coloring. This is a very patient step. It is not as thick as thin as it is. The restorator's skills are reflected in this simple thickness. It is like a chef cooking, the raw materials are all the same, and the cooking time is almost the same, but a good chef can cook excellent and fragrant effects.

The coloring was completed. After the green nitro lacquer was naturally air-dried, Tang Feng began to glaze with imitation glaze paint. Since the glaze of plum celadon was very thick, it needed to be applied layer by layer and repeatedly. As it was easy, the entire glaze process took more than three hours for Tang Feng. Then, Tang Feng sprayed a thin layer of nitro varnish with a spray gun to complete the most difficult coloring and glaze process.

Lin Muyu carefully observed the repaired pen wash again. After a long time, she nodded and said, "Well, it's great. If I hadn't watched you complete the repair with my own eyes, I'm afraid I wouldn't have found any traces of the repair."

Finally, the final step was reached. Tang Feng applied a layer of floor wax on the entire surface of the brush washing, and then polished it. The brush washing became as bright as before, recreating its original appearance.
