The solvent configured by Liu Lao is colorless and odorless, and it immediately blends with clean water when poured into the sink.
Then Liu Lao found a pair of rubber gloves and put them on, then he picked up the Li Shizhen money sword and put it into the water.
"This sword needs to be soaked for about five minutes, and then depending on the situation, I will decide whether to increase the concentration of the solvent in this sink or replace it with a solvent specifically designed to remove patina."
Liu Lao said as he took off his gloves.
Yang Jing hurriedly folded the paper with the name of the raw material for mixing this solvent that he had just written down, and then put it in his wallet.
Mixing this solvent requires a total of more than 20 different raw materials, and it is better to memorize it than to write it down.
"Xiao Yang, you have to remember one thing, it is not a bad thing to have rust on the bronze coin, the patina on the bronze coin, in fact, are the marks left by the years and the environment, there are many times, we cultural relics workers are relying on the thickness, color, firmness and so on of these patina to identify the age and authenticity of the ancient coins.
However, it is precisely because of this characteristic of bronze coins that many people who fake bronze coins will try to artificially make fake rust on copper coins to deceive buyers.
Therefore, as long as the rust on the unearthed bronze coins does not affect the reading of the money, the rust on the copper coins should not be removed."
"Also, to remove the rust on the bronze coins or bronze utensils, it also depends on the situation, you can't use those rust removal methods to remove the rust, otherwise it is easy to hurt these bronze coins, and more often it will even destroy these precious bronze coins, just like the two copper coin swords you brought today, on the surface, they look very rusty, but in fact, most of them are rust, so when removing rust, you must first use the solvent to remove the rust, if the rust is removed after a while, there is a lot of patina inside, We also need to mix another solvent that is specifically designed to remove patina."
During the waiting time, Liu Lao told Yang Jing a lot about the maintenance methods of bronze coins and even bronze utensils, which made Yang Jing feel overjoyed.
Liu Lao is the leading expert in bronze and bronze cultural preservation in the Palace Museum, and it will be an extremely rare opportunity for Yang Jing to come to Yang Jing, and Yang Jing can't use his mobile phone to record all these words that Liu Lao said.
It's a pity that the waiting time is only five minutes, and Liu Lao has not spoken for a few paragraphs, and he is about to take out the money sword.
At this time, the solution in the sink had become extremely turbid, and the money sword soaked in it was no longer visible.
Yang Jing put on rubber gloves first and said, "Old Liu, let me do this kind of work, you can guide me on the side." ” Liu Lao nodded with a smile and said, "Then you can be careful, the hemp rope of this sword is estimated to be rotten, and once the rust is removed, the whole sword is likely to fall apart." ” Yang Jing cautiously put his hand into the sink and quickly touched the sword.
To Yang Jing's surprise, this sword did not disintegrate as he imagined, at least it was still quite strong to the touch.
"Old Liu, this sword doesn't seem to be scattered, it's quite strong to the touch."
Hearing Yang Jing's words, Liu Lao also showed a look of surprise on his face, and said while wearing rubber gloves: "Don't move first, I'll see what the situation is." ” Yang Jing retracted his hand, Liu Lao carefully put his hand in, and then a smile of surprise appeared on his face.
"Haha, this sword should be made of hemp rope mixed with wire, otherwise this sword would have disintegrated a long time ago.
Well, if I'm right, this sword should have a lot of history. ” As he spoke, Liu Lao gently held the sword and left the sink, and then put the sword on the desk.
"Hehe, Lao Cai, come and take a look, the hemp rope that weaves this sword is really mixed with a lot of metal wires, look at these black filaments, aren't they the wires mixed in the hemp rope?
Well?
These two are " Liu Lao's face became solemn, he took out a magnifying glass and looked closer, and after a while, his face showed a look of surprise, "God, there are even a few golden wires mixed in here!"
This sword is definitely not something that ordinary people can have, it should be an authentic Taoist money sword!
” Hearing Liu Lao say this, Yang Jing also saw the few dark yellow filaments mixed in a small bundle of black filaments.
I don't know how many years this sword has been buried in the ground, if the ordinary metal has long been oxidized and discolored, only the inert metal of gold can be buried under the ground for hundreds or thousands of years without changing its color, at most it is dark.
Cai Yi also came up and looked at it for a while, and then said: "The shape of this sword is also different from the shape of the money sword in the north, I remember that it seems that this shape of the money sword was prevalent for a period of time in the Yangtze River Basin, right?"
” Liu Lao said with a smile: "That's right, judging from the form of this sword, it should be the Taoist money sword that was popular near Jiangnan and the middle reaches of the Yangtze River during the Jiajing, Longqing, and Wanli periods of the Ming Dynasty. ” The form of this sword was indeed different from the money sword that Yang Jing had seen before.
The money sword that Yang Jing had seen before had a sword grid between the hilt and the sword body, that is, the gauntlet, but this sword did not have a sword grid, from the hilt forward, it was directly the sword body, and the whole sword looked like a stick.
Yang Jing had never seen such a strange money sword, but when he heard Liu Lao say this, Yang Jing immediately gave Liu Lao a thumbs up in his heart.
The identification result given by the Holy Ring is that the sword was made by Li Shizhen himself in 1573, and 1573 happened to be the first year of Wanli, the second year of Emperor Wanli of the Ming Dynasty.
"Hey, Lao Liu, there seems to be a word on the blade of this sword."
Cai Yi suddenly screamed loudly, and it was obviously not an ordinary discovery to make everyone like Cai Yi scream.
"Yo, it's still your eyes that are good at ancient porcelain, I didn't even see it, but you actually saw it.
Well, yes, it seems to be an inscription, but it's covered with rust, so I can't see it.
Liu Lao also laughed and teased Cai Yi after looking at it for a while, and it was obvious that the bulge of the suspected font on the sword made Liu Lao and Cai Yi very excited.
The sword is the bulge behind the hilt of the sword, which is usually used to counterweight and tie the spike.
It would be great if an inscription could be found on an unearthed artifact like this, which is simply unsearchable, because the inscription usually has a high probability of indicating the origin of the artifact.
"It's so good!
This sword is a standard Qiankun magic sword, and it is also woven with hemp rope doped with gold wire, and there is an inscription on the sword, this sword is not simple!
No, I'll have to study this sword well, maybe it's a big discovery.
Liu Lao looked extremely excited.
Yang Jingxin said, if you can really study this sword, it will definitely be a big discovery, the sword of the medicine saint Li Shizhen, what is it if it is not a big discovery?
