"What's wrong with Professor Tao?" Seeing Tao Lin coming, Jin Yuan immediately got up and said.

"It's okay, it's okay, it's just too boring over there, come and talk to the three brothers." As he spoke, Tao Linzun leaned down and touched the copper table.

Jin Yuan handed his chair to Tao Lin and said, "Professor Tao, you sit." ”

"No, no, I have my own chair, I'll just move here." Even if he was polite to Jin Yuan, Tao Lin's hand did not leave the bronze ban, and at this time he had already determined that this should be the bronze ban of the Western Zhou Dynasty.

Tao Lin glanced at the place where he did it just now, and the table over there seemed to be the same as the one here.

The height, length, and width were all the same, but the table on his side was still hidden under the tablecloth.

"Dude, where did you get this?" Tao Lin said involuntarily.

Jin Yuan glanced at Tao Lin strangely and said, "What? What did you say? ”

"He said that this copper table, I think it's just scrap copper sold, can the holes on it be used as a table?" Iron Pathway.

Luo Qishan also said: "I know that Lao Jin, you are rich now, and now that you have seen it, you know that it is true, how can this copper table also have a hundred and ten catties?" Twenty yuan a catty, it costs more than 2,000 yuan, just put it here as a table? ”

"This is what Xiao San did, and after several days of tinkering, it was easy to cast these two tables, can I sell them as scrap copper? But if you put a few big holes in it, it's really not easy to use. Jin Yuan lamented.

The children at home are not worried!

Let him get a few tables to use, and he spent a lot of money, but he was able to build such a copper table with holes.

That's it, Jin San also told him that this was used by the princes and nobles in ancient times, and the ghost was a liar.

Tao Lin didn't know what Jin Yuan was thinking, but he found that this bronze ban was very strange, although he looked at the surface layer with a layer of rust, but if he looked closely, those rusts were only a recent period, only a shallow layer.

In this way, it turned out that it was not rusty, which was similar to the republican ding.

Tao Lin observed carefully and found that when this thing was unearthed, it was not absolutely without rust, but the degree of rust was very slight, making it difficult for people to see.

Ancient bronzes, the main component of which is copper, unearthed burial chambers have been soaked in groundwater for a long time, and the complete isolation of oxygen from bronzes is the main reason for their stainless steel.

The ancient bronzes of our country are mainly two-yuan alloys of copper and tin, which were written in the Warring States Period in the "Zhou Li and Kao Gong Ji", which has "four points of gold (copper), and tin is one, which is called the Qi of the halberd; Three points of its gold and tin are one, which is called the Qi of the big blade".

Generally speaking, the copper content is 70%-80% or slightly higher, and the tin content is about 10%-20%, in addition, the alloy often contains other components such as lead and iron.

The bronze made by Jinsan has a copper content of about 80%-83%, a tin content of about 16%-17%, and a small amount of lead and iron, which are impurities contained in the raw materials.

As the main component of bronze, copper is an inactive metal, which is generally not easy to rust under normal conditions, which is one of the reasons why these two bronzes are forbidden to be rustless.

In ancient tombs, there are generally several ways for it to corrode: under humid conditions, in the presence of air or oxygen, rust occurs and copper salts are generated;

Electrochemical corrosion occurs in contact with precious metals (such as gold, silver, etc.) under humid conditions; Copper sulfide is formed in contact with sulfur or sulfur-containing substances.

This bronze ban, although it looks a little patina, this should be caused by long-term exposure to the air, so although this bronze ban looks simple, Tao Lin is not sure what age it comes from, but judging from some ornaments, it should be the bronze ban of the Western Zhou Dynasty.

However, this casting process is very confusing.

Tao Lin chatted casually with Jin Yuan, and generally took out an instrument in his bag, put a little patina into the instrument, and soon the answer in the instrument came out.

As he spoke, Tao Lin made several appraisals in succession, all of which were the same results, and the result was realistic, this thing has a history of more than 2,500 years.

Identifying this age, Tao Lin did not have much to be happy about.

This thing is actually the same as the Republic Ding, it is actually stainless steel, more than 2,000 years of history, and there is no rust on this bronze ban, which is too strange, right?

Tao Lin was struggling, and at this time Luo Xiumei walked into the courtyard, followed by Jin Hu, who was holding a big watermelon in his hand.

"Dad, I'll bring you a big watermelon, it's still early to eat, you can eat some watermelon to quench your thirst first." Luo Xiumei said.

Jin Hu put the watermelon on the bronze ban, which happened to be on a big hole: "I'll cut the melon." ”

Seeing that Jin Hu was holding a long machete, Luo Qishan hurriedly stopped: "It's better for me to come!" It wouldn't hurt you. ”

"Grandpa is fine, this watermelon is too crisp, it should be fast when it is cut, and the watermelon will crack by itself if it is slow, I often cut watermelon at home, I will come." Golden Tiger Road.

"Dad, you just let Xiaohu cut it." Luo Xiumei said.

"Let's let me, look at the strength of my Jin family's knife skills."

As he spoke, Jin Hu waved the machete, pulled a knife flower, and immediately slashed at the watermelon, and everyone on the side saw a flash of the knife, and the machete had cut the watermelon in half.

With a bang, the watermelon was neatly split into two halves and opened.

"Oops!" Several exclamations sounded at the same time, startling the golden tiger who was going to continue cutting melons.

"What's wrong?" Jin Hu put away his knife and wanted to see what he hadn't done well.

But before he moved, he saw Professor Tao, pulling the two halves of the watermelon and looking at the bronze forbidden under the watermelon.

Just now he clearly heard the sound of the machete slashing on the bronze forbidden, and the strength was not small, otherwise he would not have heard a bang.

Seeing Tao Lin's movements, Jin Yuan said: "Old Tao, it's okay, this table is very strong, my grandson often uses watermelons to practice knives on this table, and it can't be broken." ”

Jin Hu said a little embarrassed: "My sword technique has not been practiced at home, so I always can't control my strength, and I have to cut the table every time, but this is much better than my previous days." ”

Indeed, there is not even a single knife mark on this bronze forbidden.

Tao Lin stood up, not knowing how to explain.

His actions have attracted everyone's attention, especially Li Lin, Tao Dayou, and Zhou Jie.

Because they were too familiar with Tao Lin, they all focused their eyes on the copper table under the watermelon.

Rectangular, with holes, flat, although it is a bronze, but have you never heard of such an antique bronze?

Li Lin couldn't think of such a treasure, but this is a bronze, as long as he sees the bronze, what makes Li Lin think of it is the Gonghe Ding, which is the treasure of the Western Zhou Dynasty.

Tao Dayou is not much better, after all, bronze forbidden such a thing is rare, and there is only the Tianjin Museum in China, and other places have never heard of this thing unearthed.

And the bronze ban is really inconspicuous, such a thing, even if ordinary people see it, they don't know what it is for, but they are in the antique business, as long as it is some special point of bronze, it will attract their attention, not to mention such an invulnerable bronze.

Before a few people came to their senses, the golden tiger slashed it open again.

As the watermelon became smaller and thinner, he couldn't contain his strength even more, only to hear the loud sound of the bump, and the watermelon was also cut into small pieces.

"Eat watermelon, let's do it together, I don't need to let me let this go!" Jin Yuan picked up a few pieces of watermelon and handed them to the surrounding guests.

Taking advantage of this opportunity, Li Lin and Zhou Jie rushed over at the same time.

Li Lin took a piece of watermelon and said: "I ate it once last time in Qidu City, this watermelon is really delicious, I want to eat more this time." ”

Zhou Jie didn't pick up the watermelon, but took a closer look at the copper table under the watermelon.

The force that Jin Hu used just now was not small, looking at the machete, the cold light was shining, and it didn't look like a blunt knife.

After slashing more than a dozen times like this, there is not a single knife mark on this copper table, but this is just this, this copper table is not simple!

Zhou Jie got up, picked up a piece of watermelon, turned to a few of his entourages and said, "Come here to eat watermelon, how lively it is here!" ”

Seeing that it still attracted the attention of a few little foxes, Tao Lin immediately regretted it.

It's really a mess of concern, Jin Yuan has said just now, this is Jin San's own casting, so what else is he studying, what is he careful about?

Wouldn't it be over if you bought it yourself?

Anyway, Jin Yuan himself said that this was done by Jin San himself.

Such modern handicrafts should not be expensive, didn't someone say it was worth 2,000 yuan just now?

Is it still necessary to be cautious?

Thinking of this, Tao Lin immediately said: "Brother Jin, I think these two copper tables in your house are good, why don't you sell them to my brother for collection?" ”

"Dad, what do you say? Don't forget the conditions you promised us when you came. Tao Dayou listened to his father's words, and immediately felt a little unhappy, of course, what he was most afraid of was that Li Lin was unhappy.

Jin San has dealt with Tao Lin a few times, this Tao Lin is not treated by Jin San now, the reason why he was able to follow Li Lin and Tao Dayou over this time was because he came as their special adviser, and even if Jin San wanted to sell the Republic Ding, he could only sell them, and Tao Lin had no share.

And as a reward, Li Lin will ask Jin San to make two sets of Kowloon cups for Tao Lin.

"Hehe, I'm sorry Uncle Tao, I'm also very interested in these two copper tables."

Although Zhou Jie didn't know what it was, he was right.

Li Lin said disdainfully: "You are an illiterate, what kind of cultural person are you pretending to be?" Do you know what this is? I just want to buy it. ”

Zhou Jie's face was not red and he said breathlessly: "Why don't I know what this is?" Didn't you hear Uncle Tao say that this is a copper table? ”

Zhou Jie was dealing with Li Lin, and his staff were not idle.

A young man directly took a photo of the bronze ban and sent it out.
