Tang Dynasty good brother-in-law

Chapter 254 Willow's Money Foundry
Liu Mu said that he needed a plane that could fly in the sky, which meant that it was impossible to eat a fat man with one bite.

But Yan Liben didn't understand it that way.

"I heard what you said, people can fly in the sky." Yan Liben also laughed, thinking it was Liu Mu who was joking.

She smiled, but saw Dugu Lanruo standing beside Liu Mu.

Yan Liben hurriedly tidied up his clothes: "Your Majesty, Your Royal Highness, please greet me."

"You don't need to be polite, Xueshi Yan, but I also want to thank Xueshi Yan for his paintbrush. Changping has two doubts, please explain to Xueshi Yan."

"I know everything."

Yan Liben is 23 years old, calling him a bachelor is not an official position.In the Tang Dynasty, bachelor was a kind of respectful title, which was used for people with knowledge and talent.There are also officials like the scribes in the imperial palace, and the civil servants in the Qin Palace can also be called bachelors.

The Eighteen Scholars of Prince Qin's Mansion represent the top eighteen talented literati.

Dugu Lanruo asked: "This copper coin is suspected of usurping. Sometimes my husband is too courageous in doing things, so now he is still a citizen."

This is to say, if Dugu Lan doesn't believe Liu Mu's words, this daring guy will dare to do anything.

"Returning to the princess, since the fourth year of Wude, the sage has set a new money rule. Ten coins are one or two, and one coin is one coin. But the pattern of the money face has not been customized. For example, the back of Yangzhou casting in the south of the Yangtze River has Chang The words Kaiyuan Tongbao are not custom-made by the government, but to replace the meaning of creating a prosperous world in the previous Sui Dynasty, which is indispensable for making money."

Yan Liben obviously did in-depth research, and brought a small box with his entourage.

There are seven different kinds of money in the box, three of which are written Kaiyuan Tongbao.There are also four kinds of Wude Changsheng, Tang Yuan Tongbao and so on.That is, the three Kaiyuan Tongbao fonts are different.

"Only the Kaiyuan Tongbao cast by Chang'an is written by Ouyang Xun. The rest of the Kaiyuan Tongbao are also written by themselves. The money on the market, 99 yuan and [-] yuan, are not cast by Chang'an."

"Why?" Dugu Lanruo asked out of curiosity.

"One is the cost. It costs Chang'an to mint coins. It costs one cent and six cents to cast one coin. It can be said that casting coins is a waste. The exception is the Zheng family, which costs only seven cents of a coin, but the Zheng family But they don’t want to tell the Department of Minting Money of the Ministry of Finance about their new coin casting method.” Yan Liben only talked about this, obviously this is just the tip of the iceberg.

You know, the issuance of new money has always been difficult.

But Li Yuan's Kaiyuan Tongbao has created a new era of coins. No matter which version of Kaiyuan Tongbao is, it is still used even in the braid dynasty.

"Tch, a mother Qian Fanmo's method of casting money is also worth keeping secret, I will trample him to death as soon as I drink a glass of water." Liu Mu sneered at the side.

Yan Liben also smiled: "Yes, compared to our method, it's really not worth mentioning. Besides, Mr. Mu Lang is very dark-hearted, he used the interlayer method."

"What is the interlayer method?" Dugu Lanruo asked.

Yan Liben brought a billet that hadn't been punched for the first time: "Your Highness, the upper and lower sides are made of high-quality brass, but the middle is cast iron. The billet is burnt red and pressed together, and after being stamped with ten thousand stones, it is We can never be separated again."

Dugu Lanruo looked suddenly enlightened: "At first I wanted to ask if it would be a loss to use high-grade brass."

"Obviously not." Yan Liben was very proud of the design of the mezzanine.

You must know that the current coins of the Tang Dynasty use a little more than [-]% copper, plus white wax and black tin.The willow wood has a little lead added.

If there are too many Siga, it will turn blue after a long time.

Some people make money by adding [-]% tin to bronze.

Besides the pattern, how can those sand castings compare with this exquisite stamping, and the small characters on it are still written by Yu Shinan, and all the templates used in the next ten years are written at one time.

"One stick of incense, one workbench can cast four hundred coins." When Yan Liben said this, he had a very dissatisfied tone, obviously he hoped for faster and more.

You know, this speed is much faster than turning sand and minting coins.

One stick of incense takes 5 minutes. Calculated according to the time of later generations, a workbench can produce more than 4000 coins in one day and one night, and the coinage of nearly [-] million copper coins in a year is quite impressive.

You must know that at the moment, Datang, including all the clans, the amount of money minted in a year is only [-] guan, that is, [-] million copper coins.

Moreover, there is more than one punching machine for willow, and one punching machine does not only have one workbench.

Therefore, the mintage of willow wood can only be supplied by raw materials such as iron and copper, which can far exceed the total mintage of the whole country at the moment of Datang.

With the support of Li Shimin, king of Tang and Qin, copper is not a problem.

Liu Mu supported Dugu Lanruo to sit down in a clean place: "Madam, it's a bit messy inside, you can rest here for a while, I'll go in and have a look before I come out."

"En." Dugu Lanruo nodded slightly.

Liu Mu nodded at Yan Liben, and the two quickly walked into the workshop.

In a hut, there are craftsmen making molds, and the hut is guarded by Willow's trusted servants.

Inside the house, Yan Liben took out an iron mold: "Your Majesty, this matter is a bit evil, or we will report it to His Highness King Qin for decision."

"No need, if there is any trouble in letting him be the master, he can't bear it. I don't care, anyway, I'm a small man." Liu Mu said, took the iron mold and pressed it on the inkpad, and then Leaves imprint on paper.

This head portrait is that of Tang Emperor Li Yuan.

"Silver coins that weigh this much must be made. Not too many, hundreds of thousands of them are enough."

"Lang Jun, my opinion is that it should be made of gold." Yan Liben suggested.

Liu Mu shook his head: "We also use this for gold coins, but do we have so much gold for gold coins? So we use silver ones, and remember to make some steel coins, five cents, two cents, and one cent."

"is that useful?"

"Trust me, it's useful. Think about it, the price of a bucket of millet on the market yesterday was only [-] Wen, so how much is it to buy a catty? Besides, four pieces of oil cakes cost a penny, so why only buy one piece?" Liu Muji One sentence convinced Yan Liben.

Liu Mu asked again: "Is there another mold?"

"Lang Jun, I dare not do this. You are crazy for doing this, and you will lose your head." Yan Liben stood in front of the cabinet. It was obvious that the iron mold had been made, but it was put into the thick Inside the metal cabinet with iron frame.

"Brother Yan, it's really possible."

"No." Yan Liben blocked Liu Mu, but gave Liu Mu a coin that had been made.

This money was made with the head portrait of Qin Wang Li Shimin as a template.

"It's so beautiful." Liu Mu nodded in satisfaction, Yan Liben snatched it from Liu Mu's hand very quickly, and quickly threw it back into the iron cabinet: "You don't want to take this out, I just made a few for trial production. "
