With the existing smelting conditions and forging technology of the Great Song Dynasty, it is indeed a loss to mint coins with silver.

Not to mention that the Great Song Dynasty couldn't mix things in silver, the method of minting money alone was enough to make people maddened.

The Great Song Dynasty used Fan Zhu, and in order to ensure the quality of the copper coins for anti-counterfeiting, the mother money was used to turn the sand method. The process is so complex and the output is so small that it is simply embarrassing to say that this is an act of the state.

A money-minting veteran can only mint money a day!

Think about the total amount of money in the Great Song Dynasty, how many workers and how much time does it take to mint money?

And a helper, even if he is not paid, how much does it cost to eat a day?

Therefore, the imperial court minted money, and there was no oil and water at all.

At that time, in class, Han Qi actually wanted to say that the idea of unlimited coinage in the imperial court was not valid at all. Because the more you cast, the more you lose.

Now, Tang Yi said that he wanted to mint silver coins and wanted to import silver, but Han Qi could only say that he was very stupid and naïve!

Tang Yi handed him a silver plate, and Han Qi took it and looked at it carefully......

Actually, this is no longer a silver plate, it is a silver coin. It's just that there are no square holes, and there are no positive and negative words.

It's upside down, almost half a tael, which is exactly what it looks like it's worth the same money.

"Zihao, what is this?"

Tang Yi didn't sell Guanzi either, "I mixed things, and it contained seventy percent of silver." ”

Over there, Zeng Gong glared at him and snatched it.

"What's mixed up? Why can't you see it at all? ”

Tang Yixin said, let you see, don't play chemistry anymore.

"Don't ask what is mixed first, just say, seventy percent silver, if the court uses this method to mint coins, can there be any money?"

Of course there is a profit!

Silver is not a relatively expensive metal like copper, and it can save a percent, which is a lot of profit.

"It depends on what Zihao is mixed with."

Tang Yi said: "It is mixed with iron, but it is not ordinary iron, but ferrochrome." ”

Oh! Iron! Even Zhao Zhen is not calm.

"Bring it and take a look at it!"

Iron? mixed with silver, as silver. How much benefit is that?

Zhao Zhen automatically ignored what kind of iron Tang Yi said about "ferrochrome".

Zeng Gongliang handed over the silver plate to Zhao Zhen and asked urgently: "How is the process?" ”

In fact, even if the process is a little cumbersome, the imperial court will make money. It's just that Zeng Xianggong fantasized that it would be better if the craft could also be saved.

Tang Yi smiled bitterly, "This is also the reason why the grass people have never come up with this method of mixing iron in silver." ”

"At present, I can only complete the refining of ferrochrome in my laboratory, and I cannot achieve large-scale smelting. And the smelting of mold materials cannot be realized. ”

"That's not a problem!" Zeng Gongliang waved his hand, "If you understand, I will order the Ministry of Industry to select the best smelting craftsmen to come back to the mountain to help you!" ”

Tang Yi shook his head, "It's not a craftsman's problem. ”

"What's the problem then?"

"Furnace temperature!" Tang Yi affirmed, "Chromite, Xianggong may not have heard of it. Most of the time, people confuse it with gray magnetite, which is weakly magnetic, but not magnetite, but an ore containing iron and chromium. ”

"The smelting temperature of this ore is much higher than that of normal iron ore, and the current smelting level cannot be refined."

Refine... I can't refine it... Everyone was dumbfounded.

Han Qi asked, "How much higher?" He felt that it might be that the craftsmen Tang Yi was looking for were not enough.

"At least twice the temperature of the iron smelting furnace!"

Well, twice is a bit high, then it's not a question of level.

"Is there a way for that Zihao?"

"There is a way, but it won't work out for a while."

Tang Yi studied chemistry and understood the principles, but he did not understand metallurgy.

He can smelt coal into coke to raise the smelting temperature, but what the corresponding coke oven and high-temperature ironmaking furnace looks like is not something he has learned, and he can only take the craftsman to explore little by little.

It really takes time.

When Zeng Gongliang heard it, he still had to ask for a craftsman....

"Tomorrow, the old man will send you fifty, no, a hundred craftsmen will come over, and I hope Zihao will succeed soon!"

Fan Zhongyan couldn't stand it anymore, why is it true that my apprentice is an immortal? The gods didn't call you like that, did they?

If you don't have money, you can find him, and if you can't find him, now you can find him if you make iron??

Without raising his eyelids, he whispered: "Tomorrow, Dalang will teach and start classes!" ”

Belch.... Zeng Xianggong said that this matter is as important as teaching classes!

Seventy percent silver! Add 30% iron, you can use it as 10% silver, where can you find this kind of good thing?

If it is done, the coinage alone will be a huge amount of oil and water in the imperial court. Moreover, as Tang Zihao said, even if it is imported silver, it is only profitable and not lost.

Imagine that the country of silver production was transported to the Great Song Dynasty for a pound of silver, but it was exchanged for seven taels of Song silver.....

It's no different from playing hooliganism!

Han Qi spoke at this time, "Don't be happy too early, once silver enters the market, the rich will turn to silver, and the private minting of inferior money will inevitably become more rampant." At that time, the impact on the dynasty will be even greater, and this matter must be cautious! ”

Copper coins are seriously counterfeited, not to mention silver with a higher value?

Tang Yi smiled, didn't wait for Zeng Gongliang to answer, and said first: "At this point, Han Xianggong doesn't have to worry." ”

"Oh? Why? ”

"Silver and ferrochrome coinage, ordinary people really can't counterfeit it."

"First, the smelting technology of ferrochrome, even if it is made, the private furnace will definitely not reach that level."

"Second, even if someone mixes other base metals into silver as good money, the common people will know the authenticity at a try."

"What's the mystery?"

Tang Yi arched his hand to Zhao Zhen, "Your Majesty blows the silver plate lightly, and then you will know when you hear it in your ear!" ”

Zhao Zhenhu did so suspiciously, blew lightly, and reached his ear....

I couldn't help but be surprised!

"W, where did this come from!?" I only heard the soft roar of the silver plate in my ears like a dragon's roar, and it didn't dissipate for a long time.

"Your Majesty, this is the benefit of mixing in ferrochrome. As long as you blow it, you can make a unique soft groan, and counterfeit money will never be made! ”

....

In fact, even if Tang Yi is not a chemical student, he knows that there is such a saying.

And silver plus ferrochrome is not only for the purpose of filling silver with iron, but also the anti-counterfeiting significance is particularly important.

The silver yuan of the late Qing Dynasty and the Republic of China, that is, the ingredient of "Eagle Ocean" and "Great Ocean" is this. Tang Yi just figured it out earlier than the Europeans and fooled the current people.

....

As soon as Tang Yi said this, Zeng Gongliang deliberately asked for the silver plate, tried it several times, and finally asked Han Qi to grab it and try it for a long time.

At this time, the "fat" old man walked up to Fan Zhongyan's side, "Brother Xiwen, this disciple has really earned it!" ”

Fan Zhongyan looked proud.

He didn't realize that he didn't know when the students of Guanlan and the disciples he passed on were brilliant, and the comfort in his heart was more comfortable than what he had achieved.

"Why don't you let this kid serve me some tea and let the old man get some light?"

......

ps: Turning sand coinage, the number of coins minted by one person in a day, Cangshan forgot a little, and I couldn't find it for a while. In my impression, it should be nearly 100 texts, to between 2 and 300 texts. Let's just watch, don't take it seriously. The number is not accurate. (To be continued.) )
