Kang Weihao is in his fifties, dressed in casual clothes and carrying two large lockboxes. Apparently, the lockbox contained antiques that he wanted to donate to the museum. Yu Lifei has already heard Zhang Jinjie say that Kang Weihao is a collector and wants to donate a few antiques to the museum this time. However, when a museum accepts donations, it is also necessary to pay attention to procedures.

In recent years, the domestic cultural relics and art market has been booming, while the private donations received by public museums have been declining dramatically. There are only a few donation reports in the newspapers, but they are always associated with "negative". For example, a heavyweight antique donated by beating gongs and drums last year ended up with a bleak ending of a "fake".

In the early days of the founding of the People's Republic of China, the past of great collectors who had to donate national treasures to the country despite their bankrupt fortunes is now nostalgic and infinitely melancholy. Looking at what happened to Kang Weihao, Yu Lifei was also very embarrassed. People came from afar to donate to the museum, but they asked him to go to Chen Village in the suburbs to ask Wu Wengu to verify the authenticity. With such an attitude, if you change it to yourself, I am afraid that you will have turned around and left a long time ago.

"Mr. Kang, please get in the car." Yu Lifei had already greeted Zheng Falei, and after receiving his call, he immediately drove to the gate of the museum. He admires Kang Weihao's mind very much, and if he were himself, he might not have such an awareness.

"Okay, thank you for your hard work." Kang Weihao nodded, he thought that this car was arranged by the museum, and he was very satisfied. Although after he arrived at the museum, he had to let him go to Chen Village to find Wu Wengu. But he was also very happy to let Wu Wengu appraise these antiques for him.

In fact, his antiques were originally wanted to be donated to the Provincial Museum. But the provincial museum thought that his antique era was not enough, so he didn't ask for it. The other pieces of porcelain are not accurate. This made him very sad, and then he thought of the city museum. However, the city museum also has its own procedures, and it is necessary to first enter the eyes of Wu Wengu. After Wu Wengu approves it, he will ask someone to evaluate it. Finally, the museum came forward to discuss the details of the donation with Kangweihao.

According to the current rules of the trade. Donors are generally treated and are not gratuitous. All of them are paid 30% according to the market price of the donated items. And, of course, there are the accolades associated with it.

"That's what I'm supposed to do." Yu Lifei nodded, and after Kang Weihao got into the car, he sat in the co-pilot's seat.

The ancient tomb in Chen Village has been almost excavated, and Wu Wengu's daily work is even harder. Nowadays, it is no longer possible to use a shovel for excavation, but only to use a very small brush to sweep away the soil on the ground little by little. And every curio. Even if it is just a piece of residue, it must be carefully sorted out and identified.

After Yu Lifei and Kang Weihao arrived at Chen Village, they waited for more than half an hour in the shed outside the excavation site before Wu Wengu had time to come up. This shed is no different from when Yu Lifei first came. It's just that now that the weather is cold, there are more things piled up outside, so that the wind outside can't come in.

"Hello Mr. Wu." After Kang Weihao saw Wu Wengu come in. Said very respectfully. Wu Wengu is a well-known archaeological expert in the province and an expert in antique identification. Although he is also a collector, in front of Wu Wengu, he can only be regarded as a primary school student.

"Mr. Kang. Thank you for your generosity, let's gossip and get down to business. Wu Wengu shook hands with Kang Weihao and said immediately. His work here. It can be said that it is a race against time, but even so, he feels that there is not enough time.

"Okay. Wu Lao. This time I brought a few pieces of porcelain and a piece of bronzes, and you helped me with my palms. Kang Weihao said humbly that although he is also a collector, he has absolutely no qualifications in front of Wu Wengu.

"No problem. Less, you can help later. Wu Wengu saw that Yu Lifei was also coming, and said with a smile.

"Elder Wu, I'm mainly here to learn." Yu Lifei said humbly.

"Section Chief Yu, will you also appraise?" Conway Hao asked in surprise. He always thought that Yu Lifei was just the deputy chief of the security section, and he just accompanied him to Chen Village to find Wu Wengu. didn't expect Yu Lifei to be able to enter Wu Wengu's eyes, he knew very well that Wu Wengu's vision was very high, and it was not easy to get his approval.

"I've only scratched the surface." Yu Lifei said humbly.

"Mr. Kang, if you still want to chat, then I'll go to the tomb and work for a while." Wu Wengu said with some unannoyance. His work here is measured in minutes and seconds, only others wait for him, and he never waits for others. Last time Xin Qingliang came to inspect, Wu Wengu didn't come up below. When Xin Qingliang left, he was very dissatisfied. But Wu Wengu's fame is here after all, Xin Qingliang was so angry that he couldn't attack.

"No need, Old Wu, please palm." Kang Weihao immediately picked up a lockbox from the ground, and after opening it, there were three pieces of porcelain inside, a glaze red high-footed bowl, a glaze red plate, and a blue and white vase.

As soon as Wu Wengu saw something, he immediately put on his gloves, took out a magnifying glass and a strong flashlight and put them on the table. Only then did he carefully take out the high-footed bowl, and the other two things, he asked Kang Weihao to put them away first. Many antiques are damaged due to sudden accidents when they are appraised. So when he appraisals other people's antiques, he only looks at one item at a time.

Wu Wengu looked at the high-legged bowl carefully, Yu Lifei naturally would not let go of such a good learning opportunity. He was also beside him, watching seriously. When Wu Wengu got started, Yu Lifei couldn't touch this high-legged bowl. But he also wants to test his eyesight, whether he can judge the authenticity and age of this tall bowl without touching it.

For a long time, people in the antique industry have misunderstood the glaze red porcelain, or they don't understand it at all. Because of the firing of red in the glaze, it has been intermittent, which is a little different from other porcelain. The time and process of glaze red and blue and white firing are actually about the same, but the blue and white have never been interrupted for more than 700 years from the Yuan Dynasty to the present.

The firing of red in the glaze is a stage and a stage. In the past 700 years, there have been many periods when it was not fired, which makes many people not very familiar with the red in the glaze. Or, even if you do, you don't know much.

The red in the glaze was burned in the Wu Dynasty, almost in the same period as the blue and white. It is more difficult to fire, and the rejection rate is much higher than that of blue and white, which is why it is sometimes in small quantities. Now Yu Lifei saw two pieces of glaze red at once, and he was also very surprised, this is definitely a good opportunity to learn.

In fact, Yu Lifei has always had a question about why Glaze Red does not have a literary name. For example, "blue and white", this is a literary name, very poetic. In fact, the scientific name of blue and white, or the professional name, should be called "glaze blue" or "underglaze blue".

Then "red in the glaze", correspondingly, should also have a very poetic literary name. For example, "safflower", but it is not poetic to call it safflower, because many plants in nature also produce red flowers. As for blue and white tweed, there is no such substance as "blue and white" in nature, so this name is easy to spread.

The glaze red is made of copper as a coloring agent and fired in a reducing atmosphere. The so-called reducing atmosphere refers to the fact that when firing, the furnace closes the fire door and is smoldering. In the past, the northern dialect was called "sealing the fire", which is such a feeling. The opposite of the reducing atmosphere is the oxidizing atmosphere. It is to open the fire door of the stove during the firing to let the oxygen in. And the red in the glaze is made by closing the fire door of the stove.

However, the glaze red has very high temperature requirements, preferably around 1,300 degrees, and the upper and lower levels cannot exceed 10 degrees. If the temperature is more than 1,310 degrees, or below 1,290 degrees, it is possible to fail. If the temperature is high, the color will fly and turn white. If the temperature is low, the color will turn black. Of course, such temperatures, now with a thermometer, are easy to control.

However, in ancient times, it was very difficult to see the slightest temperature difference. Only a worker with a very rich experience in pottering can see it. You know, less than one percent of the error determines the life and death of the glaze red.

The Yuan Dynasty was the era of red firing in the glaze, but because of too many failures, it could not develop. We all have the experience that when doing something, if there is a failure, we generally do not back down and will continue to practice. But if you always fail, it's easy to give up. After all, people in ancient times couldn't all be Edison, and they failed hundreds or thousands of times, but they were still indomitable.

The second firing period of glaze red is the Hongwu period next to the Yuan Dynasty. Moreover, the Hongwu period should be the vigorous period of red in the glaze. This has a lot to do with the historical period at that time. Zhu is red, and the year name "Hong" Wu is homophonic with "red". Coupled with Zhu Yuanzhang, who participated in the Red Turban Army in history, he was very interested in red. Therefore, the porcelain of the Hongwu period seen now is even more red than blue and white in the glaze. This is also unique in the entire porcelain calendar.

"Mr. Kang, is this high-legged bowl from the Qing Dynasty or the Ming Dynasty?" After Yu Lifei looked at it for a while, he saw that Kang Weihao was a little bored alone, so he walked over and asked softly.

"This depends on Wu Lao's appraisal." Kang Weihao said confidently that he was very confident in this antique. He himself is a collector, and this glaze red three-fruit pattern high-legged bowl has also been seen by many people.

"Mr. Kang, this glaze red three-fruit pattern high-foot bowl is really good, do you really want to donate it to our museum?" Wu Wengu put down the magnifying glass, carefully placed the bowl in the center of the table, and said slowly.
