Chapter 669 Fish Talisman
After laughing for a while, Chu Yulan saw what Chu Chen put on the table, and asked curiously, "Brother, did you buy something good again?"

Chu Chen smiled and said, "They're all gadgets, but there are two things that are really good!"

"Oh! What?" Everyone turned their attention.

Chu Chen smiled and took out the little arhat statue and those three things, and put them on the table.

Everyone can see that the Arhat statue is indeed a rare boutique, but the other three are rusty, not at all resembling, and shaped like a small fish. Except for Liu Sizhe, the others People can't tell what it is.

Fatty Dong looked at the three items, and then said: "Brother Chu, this arhat looks really good, but what are these three things?"

"These three are military symbols from the Tang Dynasty." Chu Chen replied.

"Ah! Is this the ancient Tiger Talisman?" Tong Hangqi asked in surprise.

Liu Sizhe said with a smile: "You are really uneducated. Can the military talisman of the Tang Dynasty be called a tiger talisman? This thing does not look like a tiger. It is obviously a fish talisman, okay?"

Tong Hangqi smiled and scratched his forehead, and asked, "I think it was tiger charms in the Qin and Han Dynasties, but why did they become fish charms in the Tang Dynasty?"

Liu Sizhe explained: "The rabbit, which is located behind the tiger in the twelve zodiac signs, was used instead, called the silver rabbit charm. Soon, the fish charm was used. Some people speculate that this may be a homophony of the "carp" of carp and the surname Li. reason.……"

After Wu Zetian came to power, she changed the fish charm to "turtle charm", and it was restored to fish charm during Zhongzong's reign.

Fish charms are generally about 6 cm long and 2 cm wide.There is a round hole in the head, which can be hung with a rope.It is divided into left and right halves, and there is a "tong"-shaped mortise and tenon in the middle to fit together.

Some fish charms are also engraved with the word "contract" in the middle seam on the bottom side. After being separated, each half of the charm has only half of the word, and the complete word "contract" can be seen when combined together, so this symbol is also called "contract".

Now sign the contract, in duplicate, with a seal on the middle seam, and each party holds a copy of the certificate.Such documents are collectively referred to as the "Contract". The word "contract" comes from the fish symbol. "

There are inscriptions on the inside of the fish amulet, indicating the identity of the person who wears the amulet or the scope of use of the fish amulet.According to the "Six Classics of the Tang Dynasty", the prince used jade fish charms, the prince used gold fish charms, and general officials used copper fish charms.Most of the fish charms handed down from ancient times and found in archaeology are copper products.

After listening to Liu Sizhe's explanation, Tong Hangqi and the others who didn't know what a fish charm was before realized what was going on.

Wen Yuting suddenly said: "So that's how the word 'contract' came about, but how could the three fish charms be together? Could it be that they were still buried together!"

"Of course they weren't buried together." Chu Chen said with a smile: "These three fish charms should be unearthed artifacts, and they should have been unearthed for a while, but the rust of the three fish charms can be seen, they are not It didn't come out of a hole."

Everyone nodded, and Chu Yulan said, "Brother, since you said it's a good thing, these three fish charms shouldn't be common, right?"

Chu Chen spread his hands: "I really don't know who used these three fish charms, but I can guarantee that one of them is a good one. You can find out which one is specific by weighing it yourself."

Hearing what Chu Chen said, Liu Sizhe and the others hurried forward to weigh it. As for Chu Yulan and the others, they felt that the things were too dirty and didn't want to do anything.

Looking at the appearance, the three fish charms are indeed not good-looking, but when you weigh them, you can clearly find the difference. Liu Sizhe is holding one with black, blue and brown hard surfaces besides the copper rust. The lumpy rusty fish charm said excitedly: "This is a goldfish charm, it must be a goldfish charm!"

Gold of the same size is about 1.17 times heavier than copper, so the difference between the two is quite large. If you know these three things, you can know the mystery of them with a little thought.

However, Shi Papi doesn't know much about antiques, and he doesn't know what fish charms are. In addition, the three fish charms are all rusty, and their appearance is too ugly. Shi Papi didn't pay much attention to them, and others probably didn't look It's easy for Chu Chen to look good.

Because in Xiangjiang before, after listening to Chu Chen's explanation, Liu Sizhe and Wang Xiaoyue were not surprised that there would be rust on gold, but others found it a little inconceivable.

Su Jinning said: "Brother Chu, this goldfish talisman is not pure gold, but an alloy?"

Chu Chen explained the reason with a smile, and everyone understood.

"Then how to get rid of the rust on it?" Su Jinning asked again.

"I heard that dipping some vinegar with a soft cloth and gently wiping can remove the copper rust, and the effect is not bad." Wang Xiaoyue said.

Chu Chen shook his head: "If it's just copper rust, it's a good solution, but the rust on this goldfish charm is not so easy to remove."

Liu Sizhe picked up the fish charm and observed it carefully, then said:
"These rust-like objects are most likely caused by the contact reaction between the silverware and copperware in the tomb and other materials in the tomb, and deposited on the surface of the gold objects. Due to the high content of sulfur in the tomb, I speculate that these rust-like objects must be Metal sulfides, such as copper sulfide and silver sulfide. Copper sulfide and silver sulfide are extremely insoluble substances, so it is difficult to remove these sulfides with general acid-base or solvent-based cleaning agents."

Hearing this, Fatty Dong asked: "Then what should I do, should I use mechanical tools to remove it directly?"

"You pig brain!" Su Jinning said angrily: "This is gold. If you use mechanical tools to remove these rust spots, won't it cause damage to the artifact itself?"

Fatty Dong spread his hands and said, "You can't use cleaning agents, and you can't use tools. Isn't it possible to keep it as it is now? How ugly!"

Chu Chen smiled and said: "Fatty Dong, your chemistry must not be very good. Don't you know that sulfide can be oxidized into elemental sulfur by the sulfur ions generated from the dissolution reaction in the presence of an oxidant, making the dissolved The balance is broken, the dissolution reaction continues, and eventually all dissolve.”

"As we all know, gold is a material that is very resistant to corrosion. It reacts chemically with other substances. Only highly corrosive aqua regia can dissolve gold. I have experimented before, using hydrogen peroxide as an oxidant, and adding appropriate other additives. The rust-like substance can be effectively removed without any damage to the gold jewelry."

Fatty Dong scratched his head and sneered a few times: "I'm really not very good at chemistry. If chemistry didn't drag me back, I wouldn't have to let my family Ningning make fun of me with my college entrance examination results!"

"Cut!" Su Jinning sneered and said, "You didn't do well in the exam yourself, why don't you let me speak out?"

"Then you don't have to keep talking!" Fatty Dong muttered.

Su Jinning sneered: "I just want to say it often, and if you have any subjects that are worse than me in the future, I will always say it. Do you have an opinion?!"

Fatty Dong said with a bitter face: "No, I have no objection!"

Everyone laughed secretly when they saw Fatty Dong's ugly face. After a while, Chu Yulan said, "Brother, let's remove the rust on it now?"

Chu Chen shook his head: "No, there will be an auction in a while, I'll leave this to Brother Zhou and the others. Let's take a look at what is written in the fish charm."

In fact, the fish talisman is still very easy to open, and the reason why it is put together is also because of the effect of rust.Chu Chen carefully used a tool to remove the rust in the gap in the middle of the fish charm. In the end, the two halves of the fish charm separated naturally.

The inside color of the fish charm is different from the surface, it looks golden, and it can be clearly seen that the material is indeed gold.

The fish symbol uses the mortise and tenon of the character "Tong", and the user's name and status are written under the character "Tong".

Everyone rushed forward to take a look, and they were a little surprised at once, because this fish charm was used by Tang Xuanzong Li Longji No. 13 Ziying Wang Li Jian.

This Li Yan is actually a very capable prince. He is frugal and frugal. According to historical records, during the Anlu Mountain Rebellion, he was named the governor of Shu County. When he led the generals across the Mianzhou River, he boarded a ship Seeing the colorful mat as a carpet, he ordered people to remove it.

Moreover, at that time Li Yanchu was ordered, because the matter was rushed and did not accept the festival, Sima Shiben of Mianzhou said that he would have people arrange festivals "to pioneer the road, enough to impress the crowd".

Li Yan laughed loudly and said, "I'm the real king, why do I need to use fake ceremonies?"

However, this Li Yan didn't know whether he had no eyesight or a little arrogance. When he arrived in the capital of Shu, Cui Yuan, who was the favored minister of Tang Xuanzong at that time, came to greet him and bowed in front of Li Yan's horse.

Li Yan didn't stop him either, which made Cui Yuan furious.Although, after Xuanzong arrived in Chengdu, Li Yan was in charge for two months, and the people were stable.But later it was still played by Cui Yuan, and he was dismissed from the inner house.

As for the reason, whether it was because Li Yan really did something wrong, or Cui Yuan held a grudge because of what he greeted, that is, the benevolent sees benevolence, and the wise sees wisdom.

Everyone was surprised to see that this goldfish talisman was used by Tang Xuanzong's son. After seeing it, Chu Yulan asked, "Brother, is this fish talisman worth much?"

Chu Chen said with a smile: "The Tang Dynasty fish charms we see now are generally copper fish charms, gold ones are very rare, and this fish charm is still very well preserved, which is even more rare. But, this kind of thing Because it is rare, there are basically no fish charms on the market, and I have never seen this kind of fish charm before, so the specific value is really hard to say. However, I use it for collection anyway, and I will not sell it. The market value is unknown. Not too concerned."

Everyone nodded and agreed.

To Chu Yulan and the others, the fish talisman was actually nothing interesting, and the fish talisman was still full of rust, so they lost interest after looking at it for a while.

Looking at the time, it was almost one o'clock, Liu Sizhe said, "Brother Chen, let's go to the auction right now!"

"Okay!" Chu Chen nodded, and then said, "Actually, there are not many raw materials in today's auction, so you might as well go to the store to pick the raw materials for fun."
