Yu Yao continued, "Don't talk about the pit, it's a heirloom, and I don't dare to accept it! I asked a few more questions because I heard him talk about Hongchang's dredging." ”

"Bronze disease?" Pu Jie thought back to the rust on the bronze, "You mean pink rust?"

"Yes. This bronze slur, he should not be lying, because the characteristics of the puddle rust are obvious. However, it is mixed with light green powdery spots, which are pink rust. ”

Pu Jie shook his head, "It's a pity, something from the Shang Dynasty!"

"It's a pity! This is not from the Shang Dynasty!"

"Huh, didn't you just say it was a pit?"

"A pit is a pit. This is the Ming Dynasty imitation of the Shang Dynasty bronze Wei, and then for some reason sank into the river. Even if it is Shenjiang in the Qing Dynasty, it is still a pit. ”

"Ming Fang?" Pu Jie scratched his head, "The technology is high enough!

"The bronze antique of the Ming Dynasty is a batch of fine products with a very high standard. During the Republic of China, many foreigners bought antique bronzes from the Ming Dynasty and brought them back to China as real things of the last three generations. Yu Yao responded, "So, if this thing doesn't have a bronze disease, it can be regarded as an imitation of the ancients, and it's not a bad thing!"

Pu Jie looked at Yu Yao, "You said that this thing is really so contagious?"

Originally, the tin plague was used to corrode on pewter, but later it was used on bronze, because bronze is a copper-tin alloy. ”

Bronze disease is generally said more in the archaeological circles, and in the antique circle, it is said that there is more rust.

From a scientific point of view, the basis of bronze disease is the rust containing chloride on the bronze, which can interact with air and water vapor to corrode in circulation, and in the end, the bronze will become a pile of powder!

Of course, even the bronzes in the pit are not all rusty. Whether or not powder rust can be formed mainly depends on the environment in which the bronze is in the "pit", such as the tomb or the soil does not contain chloride, then there will generally be no powder rust, but common green rust, red rust, crystalline rust and so on.

An important substance in rust is cuprous chloride, which can be cyclically infected because cuprous chloride is a photosensitive substance. With the rust, there is light again, and at a certain humidity, it will only get worse and worse.

If you put a piece of bronze with rust in the middle of a pile of bronzes without rust, the rust will spread quickly.

That's why Yu Yao was very careful, threw away the gloves and cotton cloth in the bag, and washed his hands more safely. Because in this Gegu Zhai, there are also bronze vessels.

Pu Jie thought about it for a while, "I remember that some copper coins that are raw are also rusty, and they seem to be able to be washed off!"

Yu Yao nodded, "Yes, copper coins, especially those that are not of high value, of course you can." Use a knife to scrape off the rust, and then configure the rust removal solution to brush it. But large bronzes are very difficult to deal with, scrape off the rust, and then brush with a solution, if you destroy the ornamentation, the value is not a little loss!"

After a pause, Yu Yao said again, "Of course, it also depends on the severity of the rust, if it is slight, it is estimated that the master can handle it." However, if it has penetrated deep into the copper, even if it is disposed of, it will be a remnant!"

"No wonder the bronzes are so well protected in the museum!" Pu Jie sighed.

"Among the unearthed cultural relics, there are also rusty ones, and after some restorations, there is no clue, which also depends on the level. Yu Yao lit a cigarette, "This bronze canon, I don't think it's serious, if it's not a Ming imitation, it's really from the Shang Dynasty, if the price is right, you can actually collect it!"

"Huh, you dare to accept the heavy weapons of the pit?"

"Why don't you dare?"

"When did you get so high?"

"You didn't understand the point, what I said was 'if the price is right'! The right price means that the money for the reward is more than the money received! I helped the state collect a Shang Dynasty bronze and made a small amount of money. What's more, the state organization repair is definitely more capable than us. ”

"Damn! It turned out to be fame and fortune, killing two birds with one stone, you are playing this abacus!"

"It's a pity, it's a copy. Yu Yao shook his head, "It's not worth it." ”

Pu Jie hummed and asked again, "What were you muttering at the door when you sent him away?"

"I told him about the rust, tell him to be careful, don't infect the other bronzes. ”

"Wow, you're really well served. ”

Judging from his reaction, he didn't believe it at all, and thought that my motives were not pure. Yu Yao waved his hand, "No matter, I have said what should be said, and whether I listen to it or not is his blessing and misfortune." ”

"Hey, you said that since it also comes from the silt at the bottom of the river, will the 'startled salamander' also have pink rust?" Pu Jie thought of this.

"You can really worry about it. I don't think so, from the point of view of 'soul destroying', the anti-corrosion technology is very good, and I expect the same is true of the 'startling salamander'. Isn't that Yue Wang Goujian sword also a thousand-year-old stainless steel?"

In fact, although Yu Yao said so in his mouth, he had been faintly worried in his heart.

What he was worried about was that it was too upside down.

Taidian Fangding is different from Yuewang Sword, in terms of material, it is an ordinary bronze and has not undergone special surface anti-corrosion treatment.

If the Taidian Fangding is also hidden somewhere at the bottom of the river, in case it is infected by silt and has powder rust, if it is very serious, even if it can be found, it will be troublesome!

However, this matter has not been brushed up yet, so I can only wait for He Wenguang's news.

Pu Jie also lit a cigarette, no longer dwelling on the topic, and instead asked, "I said, that set of Western Han jade sword ornaments, if you don't find a buyer again?" Find someone who knows how to sell it at a good price, and the diaphragm should kill the one who drives the KTV!"

"Pull it down, it's quite difficult to find a complete set of jade sword ornaments on the market now, so I decided to leave it for collection. ”

"How many things have you left behind, and what do you want to do, open a museum?"

"It's not impossible. Yu Yao smiled, "The key is that there are some things that I really don't want to do!"

Pu Jie dusted off his cigarette ashes, "Don't say it, I'm a halfway monk." As for you, you have been exposed to Uncle Yu since you were a child, you and I are different from accumulation and addiction. ”

"Maybe!" Yu Yaoxin said, in fact, he was originally similar to Pu Jie, as long as the profit was big enough, I am afraid that there is nothing that cannot be sold, even if there is no shortage of money for the time being.

However, after his eyesight improved, many of his ideas gradually changed.

For example, collecting antiques, in addition to appreciating and pleasing to the eye, there is also the inheritance of history and culture, which is becoming more and more important in his heart.

Seeing that it was time for dinner, Pu Jie touched his stomach, "Okay, let's not discuss, let's eat?"

"Good. Yu Yao came back to his senses, and when he got up, Pu Jie looked at the door and said, "Huh, why is he here?"
