The sledgehammer is smashed into shape and thrown into water to cool down.

Fished out of the water, someone sharpened the burrs and handed the money into Han Jiang's hands.

Coins are smashed out by hand.

At the end of the day, there were a few coins that were very special and brightly colored.

Han Jiang asked, "What's the matter with these pieces?" ”

"Back to Shaojun's words, there is still a little remnant, and the coppersmith added two points of tin to it. Tin coins will be a little harder and more wear-resistant, so just try it. ”

Han Jiang didn't study metal, he only knew that the zinc-copper alloy was brass, and the ratio might be four to six, and he didn't know the details.

Therefore, he didn't know that there was another kind of tin brass, which was to add one percent of tin to the zinc-copper alloy, which would make the brass extremely bright.

Han Jiang instructed: "Coppersmith, use this recipe for me, get a few small gold ingots of one or two out, and I'm going to fool my father." ”

A few craftsmen snickered, but they immediately got busy.

A master craftsman said beside Han Jiang: "Shaojun, copper is copper, even though this one looks similar to the color of gold, there is still a difference, and the copper voice is light and brittle, gold is muffled, and the copper is hard and soft to buy, this is afraid that the lord will not be able to deceive the monarch." ”

"Fun, have fun, do you understand. Now what you want to study is, how to produce in large quantities and reduce costs, this is not used in our Great Song Dynasty for the time being, it is used to fool the gold people, one money for five dollars, is it appropriate? ”

The master craftsman replied: "Shaojun, if you want to make a large number of water, you must first build a large water turbine, and relying on manual forging is not afraid of labor, but too slow." Next is the raw material, there is a ban on copper ore in the imperial court, and there is the composition of this bright gold and copper, which is at least twice as expensive as lead, which will be a loss. ”

"Shaojun, the little one is a thief, Meng Shaojun gives him a way to live, and the little one has something to say."

The one who spoke came out of prison, and his name was Liu Hong.

The man, but took a woman's name, I heard that he was always sick when he was a child, and he was afraid that he would not be able to raise it, so he took a woman's name.

"Speak."

Liu Hong said: "Make a big money, two and a half dollars heavy, a little smaller hole reconstruction, one money is ten dollars, just say that the ore of our money is the ore in the gold and copper mine, many people know, gold and copper even ore." The Jin people are barbarians, and they know a bird. ”

His own master also said: "If one dollar is ten dollars, this must be worth it." ”

Han Jiang asked again: "Then the cost of Shafan is low, or is it low forging?" ”

Liu Hong replied: "Since it is gold and copper, it must be made more beautifully, this iron fan should be made ten times finer, and it is impossible for people to imitate it if they want to add patterns, and this formula must be kept secret." Since Shaojun can get us out of prison, he naturally has a way to silence those who know this secret. ”

Han Jiang didn't speak, and glanced at Han Wu, who had two knives pinned to his waist.

Han Wu took a step forward: "Shaojun, the dead will definitely be able to keep secrets. If there is a mistake, there is no need to punish the young king, after I killed the person who leaked the news, I cut off my head and made amends. ”

Han Jiang nodded: "Let's all stay first, Han Wuming will go to Yanzhou to find a safe place, on the surface it is a lime workshop, but secretly it is our family's money workshop." The place must be big, I'll get you a few hundred young girls when I go back, but don't be picky, it may be a widow. ”

Everyone laughed.

Compared with Han Yanxuan's strictness, although Han Jiang is ruthless, he is very kind, and the rewards are generous enough.

Liu Hong took a step forward: "Shaojun, I think the billet should be made first, not a red-hot copper ring." Although there is one more process, if it is made smoothly, it will definitely be better to forge it, and the cost will be less, please consider it. ”

"You're right. I said, you can try better. Cost and quality are important, find the most reasonable degree. After Han Jiang replied, a servant directly took a silk and put it in front of Liu Hong.

Liu Hong hugged her fists: "Xie Shaojun rewarded, after the little one was arrested, my mother-in-law threw me down and ran away, I want silk is useless, there is wine, meat and line." ”

Han Jiang shook his head: "When you have money, whether it is someone who escaped from the north or a disaster at home, there is naturally a good family among the homeless people who can live in peace. ”

Liu Hong knelt down and kowtowed heavily: "Xie Shaojun." ”

"Do things well first, my rule is that if you do something, you will be rewarded accordingly, and those who want to make money for themselves when they don't do anything will end up very bad."

After Han Jiang finished speaking, Han Wu stepped forward: "Yanzhou, a few money-making stewards in the house were beaten into meat puree, put them in boxes and threw them into the river. An embroidery girl, embroidered the best quality, the palace is happy, and the reward is ten gold. I can't read, but I know that Shaojun's words are the rules of the house. ”

"Understood."

Liu Hong naturally understood that the gang of them had real skills when they were fished out of prison, and a few slippery heads died on the torture rack on the day they came out.

"Okay, killing sheep, it's hard work today."

"Xie Shaojun."

Han Jiang returned to his yard with a bag of new money and three small copper ingots.

Han Yanxuan didn't pass the meal, and he was still reading the official document in the study.

Wu Song was reading the script to pass the time.

Han Jiang entered the room and put a few small copper ingots on the table, Wu Song's eyes lit up: "Gold, this shape is really beautiful." ”

Han Yanxuan said without being salty: "Fake, the voice is too hard." ”

"Daddy wise, this is copper."

"Copper!" Han Yanxuan's eyes lit up, and he quickly picked up one and looked at it carefully in his hand: "I've seen the Lianshi for my father, it's not, it's brighter than the Lianshi, the Lianshi is still gray, and it will turn cyan after a long time." ”

Han Yanxuan originally thought it was gold-plated, but he didn't expect it to be copper.

Wu Song also took a piece: "This is fool gold, not quite right, more beautiful than fool gold." ”

Han Jiang didn't know what the fool Jin was.

However, when refining just now, a coppersmith said that copper ore and calamine had been used for refining a long time ago, some with tin and some with lead. When it was first refined, it looked like gold, but after a short time, it began to change color and turn blue, and some rusted and turned green.

Han Jiang knew that calamine should be a type of zinc ore.

The coppersmith also said the formula, a pound of copper, a pound of calamine, and a pound and a half of brass were smelted.

As for how many impurities are in this brass, according to the coppersmith, it is all a matter of luck, and not all calamine can be smelted into brass.

Only then did Han Jiang open the bag and put the brass money in the bag on the table.

"Daddy, the craftsman said that the production should be more fine, one coin should be ten yuan, it is definitely not possible to spend this money in the Song Dynasty, if it is placed in the Jin Kingdom or Western Xia." Han Jiang knew that in this era, it can be said that the money used in the whole of Asia is Song money, and even as far as Africa, and even the Mediterranean.
