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

Snap out of the water, someone grinds away the burrs and handes the money to Han Jiang.

Moneys are smashed out by hand.

In the end, there were a few coins that were very special and the color was extremely bright.

Han Jiang asked: "What's wrong with these ones?"

"If you go back to Shaojun, there is still some residue. The coppersmith added two parts of tin to it. Adding tin coins will make it harder and wear-resistant, so let's try it."

Han Jiang did not learn metals. He only knew that zinc-copper alloys were brass, and the ratio might be between four and six, and he didn't know the details.

So, he didn't know that there was another type called tin brass, which added one percent of the tin to the zinc-copper alloy, which would make the brass extremely bright.

Han Jiang instructed: "Where is the copper smith, use this recipe for me and make a few small gold ingots of one or two. I want to fool my father."

Several craftsmen laughed, but they immediately started to work hard.

A master craftsman said beside Han Jiang: "Shaojun, copper is copper. Even though this one looks similar to gold, there are still differences. Moreover, the copper sound is light and crisp, and gold is muffled. If you buy copper hard and soft gold, you are afraid that you won't be able to deceive the Lord."

"Fun, do you understand it? What you want to study now is how to produce large quantities and reduce costs. This is not used in our Song Dynasty for the time being. It is specifically used to fool the Jin people. Is it appropriate to exchange one ounce for five ounces?"

The big craftsman replied: "Shaojun, if you make a large amount of production, you must first build a large turbine. Manual forging is not afraid of being exhausted but too slow. The next step is the raw materials, the imperial court has a ban on copper ore, and the bright gold and copper ingredients are at least twice as expensive as lead, which will lose."

"Shaojun, the youngest one is a thief. The youngest one has something to say."

The one who speaks is from prison, called Liu Hong.

The man named a woman. I heard that he was always sick when he was a child and was afraid that he would not be able to raise a woman, so he named her.

"speak."

Liu Hong said: "For big money, two and a half coins are heavy. The holes are made smaller, and one qian is used as ten qian. Let's say that the ore of this money is the ore in the gold and copper mine. Many people know that the gold and copper mines are barbarians, and they know a bird."

His master also said, "If one ounce is used as ten ounces, it will definitely be worth it."

Han Jiang asked again: "Why is the cost of Shafan low or the forging low?"

Liu Hong replied: "Since it is gold and copper, it must be made more beautiful. This iron pattern must be made ten times more delicate, and the patterns make people imitate it. This recipe must be kept confidential. Since Shaojun can take us out of prison, there is naturally a way to shut up those who know this secret."

Han Jiang didn't say anything, and glanced at Han Wu with two knives on his waist.

Han Wu took a step forward: "Shaojun, dead people can definitely keep secrets. If there is any mistake, there is no need to punish them. After I killed the person who leaked the news, I cut my head and apologized."

Han Jiang nodded: "Everyone stay here first, Han Wuming goes to Yanzhou and find a safe place. On the surface, it is a lime yard, but in secret it is our Qianfang. The place must be big. I will get you hundreds of young girls, but don't be picky, it may be a Japanese girl."

Everyone laughed.

Compared to Han Tuozhou's sternness, although Han Jiang was ruthless, he was very kind and rewarded generously.

Liu Hong took a step forward: "Shaojun, I think we should make a blank first, rather than a red-burning copper ring. Although there is an extra process, if it is made smoothly, it will definitely be better forged, and the money will be less. Please consider it."

"You said it well. 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 piece of silk and placed it in front of Liu Hong.

Liu Hong clasped her fists and said, "Xie Shaojun, after the young man was caught, the wife threw me away and ran away. It was useless for me to ask for silk, wine, meat and everything was fine."

Han Jiang shook his head: "When you get rich, whether you escape from the north or encounter disaster at home, there will naturally be a good family among the refugees who can live a peaceful life. When you marry a wife, I will find you a few Japanese concubines, including children and daughters. This is what it means to live. Follow me, Han Jiang. Since I am working hard for me, I will give you wealth."

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

"First do things well. My rule is that if you do things, you will get corresponding rewards. If you don't do things, you will have a bad ending.

After Han Jiang finished speaking, Han Wu stepped forward: "Yanzhou, a few officials who made money in the mansion beaten into meat paste, put them in a box and threw them into the river. An embroidered the best, and the palace was happy and rewarded ten gold. I couldn't read, but I knew that Shaojun's words were the rules in the mansion."

"clear."

Liu Hong naturally understood that the group of people they had the real skills to catch from prison, and they died on the punishment rack on the day they came out.

"Okay, thank you for your hard work today."

"Xie Shaojun."

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

Han Tuozhou didn't pass on the meal, and he was still reading official documents in the study.

Wu Song was watching the verbal book and passed the time.

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

Han Tuozhou said indifferently: "Fake it, the voice is too hard."

"Dad is wise, this is copper."

"Bronze!" Han Tuozhou's eyes lit up, and he quickly picked up one and watched it carefully in his hand: "I have seen a crocodile stone for my father. This is not. It is brighter than a crocodile stone. The crocodile stone is still gray, and it will turn green over time."

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

Wu Song also took a piece: "This is fool's gold, it's not right, it's more beautiful than fool's gold."

Han Jiang didn't know what fool Jin was.

However, when I was refining just now, a copper smith said that I had used copper ore and calamine for a long time, some were added with sten and some were added with lead. When it was just refined, it looked like gold, but it started to change color and turn blue after a while, and some turned green after rusting.

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

The coppersmith also mentioned the formula, one pound of copper and one pound of calamine, and one pound of brass is refined.

As for how many impurities there are in this brass, according to the coppersmith, it depends entirely on luck, and not all calamine can be used to make brass.

Han Jiang then opened the bag and placed the brass coins in the bag on the table.
