Sun Yi said to the two blacksmiths: "I have a tin pot here, you can see how to help me make tin foil." Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

As he spoke, Sun handed over the tin pot.

The master who wielded the hammer took it, but he didn't expect the tin pot to be very heavy, and he almost missed it. When I opened the lid of the tin kettle, I saw that it was full of copper coins.

The master who wielded the hammer immediately quit: "Do work for the master, how can we collect the master's salary!" Get the money back! ”

Sun Yile said hehehe: "That's not wages, that's another job." These copper coins have been black for a long time, and the surface is blackened, you see if there is any way to deal with it, I will pick some good money out. ”

The blackening of the surface of the copper coin was formed by oxidation, and Sun Yi thought about asking the two masters to polish it and remove the oxide layer on the surface.

The master who wielded the hammer was also happy, "This tin pot is a good thing, do you really want it?" ”

Sun nodded a little.

The master wielding the hammer looked at the tin pot with some pity and asked, "How thick does the tin foil you want?" ”

Sun Yi replied: "It doesn't need to be too thin, it's thinner than this tin pot, and it doesn't need to be thin and thick." ”

Sun Yi was in a hurry to get the tin foil as soon as possible, the two masters in front of him did not have modern forging tools, so they could only hammer and hammer, if they were too serious, Sun Yi estimated that he would have to work until dark, so Sun Yi asked to put it very widely.

The hammer master replied happily: "That's easy to do, you wait a minute." ”

The master poured out all the copper coins in the tin pot with a bang, clamped the tin pot with tongs and put it on the fire.

The melting point of tin is only 230 degrees Celsius, and after a while, the tin pot begins to soften, and the master immediately throws the softened tin pot into a small iron spoon.

The deformed tin pot twisted a few times in the iron spoon, and slowly turned into a pool of silvery-white tin water.

Taking advantage of this, the master buckled the two cutting boards for striking iron face to face and put them on the ground, and used several small wooden sticks to cushion them in the middle of the cutting board.

Using an iron rod to skim off the scum on the surface of the tin, the master picked up the iron spoon and poured the tin into the gap between the two cutting boards.

With one hand, the master neatly removed the small wooden stick between the cutting boards, got up, and stood on the cutting board.

Still holding an iron spoon in his hand, the master took off his shoes with one foot, felt the temperature under his feet, and said to Sun Yi: "It will be fine in a while!" ”

Sun Yi was dumbfounded. He thought that the tin foil was also calcined, but he didn't expect that the master of the Ming Dynasty, who was good at casting, was actually "casting" tin foil. And he cleverly used his weight to make the tin foil thinner.

In the past, Sun Yi had heard rumors that after the invention of artillery, Westerners who were good at forging would not cast such a large cannon body, and they also went to the Ming Dynasty to learn casting technology. This time, Sun Yi believed it.

After only a few minutes, the master put on his shoes and said, "It's done!" ”

Lifting the cutting board, a shiny flat tin foil appeared.

Sun Yi squatted down and felt that the tin foil was still a little hot.

The master stroked the tin foil with one big hand, observed it from different angles a few times, and said: "There is still some unevenness, I will beat it a few more times, and the storage can show the figure!" ”

Sun Yi hurriedly stopped, "It's good, it's good, that's it." ”

The degree of processing of this tin foil has exceeded his requirements.

The master asked, "What are you going to cut the foil into?" ”

Sun Yi thought about it and replied: "A thin strip one inch wide and three inches long." ”

Only then did the master put down the iron spoon, took out a large pair of scissors, and cut them according to the size Sun Yi said.

The other master next to him was not idle. He poured out the copper coins and put them in a small pile of sand. Out of nowhere, he took a jar and poured the liquid from the jar into the sand. Then the master began to stir the wet sand with an iron rod, and from time to time he stood up and stepped on his feet.

Sun Yi walked over curiously and picked up a scattered copper coin. The coin has begun to glow with copper's characteristic red color.

This is by no means the effect of the sand rubbing.

Sun Yi asked the master: "Are you particular about the water you poured in just now?" ”

The master smiled honestly and said, "That's not ordinary water, it's a special copper rubbing water." As a blacksmith, you often have to help someone sharpen a knife, polish a bronze mirror or something. ”

Sun Yi suspected that the so-called rubbing copper water was an acid.

But when Sun smelled it, there was no sour smell, but a stench.

Sun Yi asked: "What is the match for rubbing copper water?" ”

The master was about to answer, but was loudly suppressed by the master who cut the tin foil.

"Master, do you think this kind of chaff is okay?"

The chaff in the shouting master's hand is no different from other chaff, obviously deliberately interrupting.

Sun Yi understood that the recipe for rubbing copper water was the blacksmith's cost to eat, and he was obviously unwilling to let outsiders know.

Sun Yi won't delve into it.

At this time, the copper coins in the sand were picked up one by one, and all of them were red.

It was only two minutes before and after, and Sun Yi thought about it, China entered the Bronze Age so early, and there must be some advanced supporting technology.

Taking a piece of tin foil, Sun Yi asked the master to cut two slender triangles diagonally. Thread the sharp corners of the tin strip into the hole of the copper coin, then wrap it around the copper coin twice, and use a small hammer to smash and compact the tin foil and copper coin. Sun Yi said: "Just like this, help me make copper coin tin foil skewers." ”

It's just too easy.

The three of them chatted while working.

The honest copper water master said: "Master, I heard that when the iron is struck in Foshan, there are ten boys and girls standing on both sides, while fanning the red-hot iron, while singing non-stop, so the iron in Foshan is smelted well, why don't we try it too?" ”

Sun Yi made money skewers in his hand, lowered his head and said, "You have to mention this matter to Wang Erniu, it's useless to tell me." ”

The master replied, "Yes." But Niu Wa is unreasonable, laughing at the low donkey, and there is no way to do this. I don't even have a sheep, where did I get a donkey! ”

Sun has always been happy.

Sun Yi would not be stupid enough to explain to the people of the Ming Dynasty that it was a feudal superstition for boys and girls to sing good iron, but to encourage this master to have the courage to explore.

Sun Yi gave him a bad idea: "We really don't have enough manpower. Why don't you sing alone when you strike iron in the future, and if you can really make good iron, let's add people to sing together? ”

The master was a little disappointed, so he had to admit it.

Sun Yi said again: "But the workshop is indeed too small for the two of you. We have a group of orphans in our camp now, and I will send a child to help you every day from now on. ”

The master grinned happily, "That's the best, the doll and I can take turns singing!" ”

The three of them quickly made all the tin foil into "money strings".

There were still a lot of copper coins left, and Sun Yi arranged to melt the remaining copper coins and draw them into thin copper wires.

Copper is much softer than iron, and the two masters said that there is no problem, and they can pull it up when the dinner comes.

Sun Yi picked up a longer piece of wire, strung the "money strings", bent them into a circle, thanked the two masters, and left with the "money strings".

Halfway through, Sun Yi opened his mobile phone and checked, it turned out that the so-called rubbing copper water was ammonia, no wonder there was a smell.

The clanging sound of striking iron sounded again behind Sun Yi, and this time there was a high-pitched singing voice accompanied by the sound of striking iron:

"Mao Gechu's kiss, you are the tip of my brother's heart......"
