Twenty days later, the weather is getting hotter.
Lihu's special pottery pot for smelting was finally completed, and he excitedly went to find Mufeng.
Wooden Feng was overjoyed when he learned that the clay pot had been fired, and decisively began to smelt copper.
The main material for copper smelting is copper. He now has two options, one is to directly use the pure copper ore he got from Xiong Da, or the other is to smelt copper from the copper ore himself.
Mu Feng, eager to see Jiang's first batch of weapons come out, chose to use pure copper ore.
In this way, he saved a process, and only needed to smelt tin and lead ore.
Tin ore is relatively simple to handle. The tin ore is crushed into small particles, fired in a fire, and the tin flows out. What floats on the surface is magazines, and what sinks to the bottom is the metal part.
The next step is purification, which is to remelt the tin with impurities, repeatedly extract the metal part, and finally obtain high-purity tin.
The refining of tin is not complicated, but it is a little dangerous.
After Mu Feng demonstrated it himself, and explained the main points to Li Hu and the others, he turned to lead smelting.
The smelting of lead is a bit complicated, although there are many methods, but there is only one method that Mu Feng can use right now - the burning method.
The fire method needs to melt lead ore into lead oxide first, and then smelt the lead oxide, coke and limestone obtained by melting in an ancient furnace.
But Mufeng didn't have limestone at hand, so he tried to use pure plant ash instead, but it worked!
After two processes, he also successfully obtained crude lead.
As for the purification steps of crude lead, it is almost the same as that of tin ore, that is, the process of repeated purification.
This repeated purification back and forth took another five days.
Mu Feng couldn't help sighing: "No wonder it took so long to smelt metal in the course of history. Not to mention the poor conditions, the craftsmanship is also a big problem! If I don't have such a heaven-defying existence of the system, I'm afraid that any link There is a possibility that the furnace will blow up and kill people!"
Right now, he has three metals with the highest purity that he can get at present, and the next step is to melt them in one furnace.
Pure copper has the highest melting point, but its hardness is not enough. It needs to add a certain amount of lead and tin to become tough and hard.
There is a ratio problem involved here.
In his previous life, Mu Feng studied bronze wares, and he remembered that the proportion of bronze wares made in ancient times was probably in the range of "six to one", such as:
The ratio of copper to tin in Zhongding Zhiqi is six to one;
The ratio of copper to tin in the ax and catty is five to one;
The ratio of copper to tin in Ge Ji Zhi Qi is four to one;
The ratio of copper to tin in the big blade is three to one;
The ratio of copper to tin in the cut arrow is five to two...
And adding a small amount of lead between the two ratios can increase the hardness!
Mu Feng compared these ratios, and thought about the weapons he wanted to make, including arrowheads, knives, and spear heads. There were also three ratios involved, namely five to two, three to one, and four to one.
As for lead, he himself was not sure how much to add, so he had to try to add half of it.
Because it was the first time to try the three metals, Mu Feng didn't dare to refine too much at once, for fear of wasting the metals that had been refined with great difficulty.
As for the weighing of the proportioning ratio, there is no trouble for him without a scale.
He took two pieces of animal skins and wore them with leather ropes. He found a stick and tied it with a rope to hang it in the middle, making it look like a balance. Roughly equal weights of metals are then proportioned from parts by parts.
In this way, the problem of metal ratio is solved.
The next step is the most critical step, which is smelting.
The purified metals are not easy to divide at this time, so the three kinds of metals cannot be crushed for smelting, and the process naturally slows down.
This process can be regarded as the most dangerous and troublesome process so far.
Because these three metals must be manually stirred after melting to better mix together.
But the problem lies in the high temperature of hundreds of degrees. Wood, bone utensils and so on cannot be stirred.
This made Mu Feng very anxious. After thinking about it, he suddenly thought of a black metal stick that he had captured from defeating the Manglong tribe before, and his eyes lit up: "That thing is cold to the touch, and it doesn't even show a mark when you knock it on a stone." Yes, it should work!"
So he hurried back to the earth building and took the stick of unknown metal, and watched the "three golds" in the big pottery pot melt.
Except for the three people who were in charge of burning the stove, everyone else was sent away by the wood wind.
As for himself, he also put on a leather coat all over his body to prevent the solution from bursting out.
Everyone looked at Mufeng from a distance, holding their breath and waiting for Mufeng to stir the solution and then pour the mold.
Mu Feng looked at the "three golds" that melted into bright yellow, felt the coming heat wave, took a deep breath, and used his homemade leather gloves to stir the metal sticks tied with wooden handles.
The sound of "chi chi chi" kept ringing, Mu Feng was also very disturbed in his heart, subconsciously raised the stick, and found that the black stick was safe and sound.
"It's useful!" Mu Feng was overjoyed in his heart, regained his energy immediately, and hurriedly started stirring while his hands were not hot.
After stirring for about a minute, Mu Feng felt a heat wave rushing towards his face, which was too hot for him to bear.
In desperation, he had no choice but to pick up the animal skin and dip it in the water prepared next to him, apply it on his face, and continue to stir.
After repeating this for several times, he stirred back and forth for no less than five minutes. He really couldn't stand the temperature, and he estimated that it was almost the same, so he stopped.
After stopping, he quickly picked up the prepared clay pot, extended the handle to scoop out some metal juice, and quickly poured it into the prepared mold.
Arrows, knives, axes, gun heads...
At this time, Mu Feng didn't care about the proportions and disproportions, and excitedly poured the molds one by one, and then gave up.
"Okay!" Mu Feng clapped his hands and laughed.
All the people who were watching from a distance came forward together, looking at the copperware that was gradually cooling and solidifying in the mold, they asked excitedly, "Are you ready?"
Mu Feng nodded and smiled, "Now we're just waiting for it to cool down naturally!"
So another long wait...
After more than an hour, Mu Feng reckoned that the bronze wares had already taken shape, so he fetched a clay pot of water, carefully removed the bronze wares from the clay mold, and put them in the water to cool down.
With a sound of "chi", the surface of the water was covered with steam, and everyone was startled.
Mufeng cooled the copperware one by one, then picked up an arrowhead, looked at it, weighed it in his hand, then threaded the hard rattan prepared in advance on the arrowhead, and held the arrowhead on a stone in front of everyone. Grind up.
In order to be quick, he only sharpened the tip of the arrow, and it took a long time.
Just when everyone was impatient to wait, he finally put away the arrow, wiped his sweat, no matter his forehead and face were covered with dust, and shouted excitedly: "Bring the bow!"
Soon someone handed over a double-piece bow, and Mu Feng weighed it, but without saying a word, he set the bow and shot at a hard black iron tree in the distance.
The black iron tree is the hardest wood in Dongshan. In the past, when Han Shu and the others practiced arrows, they often competed on who could leave deep arrow marks on it, even if they were stronger.
Naturally, Mu Feng also tried.
At that time, he used a three-piece bow, which only left a deep impression on the bark.
But that bamboo arrow was shattered even the tip and the body of the arrow.
But now Mufeng only uses two bows, the situation is quite different.
Just hearing a "whoosh", the arrow pierced directly into the tree trunk for an inch, and the body of the arrow trembled endlessly!
"This..." Everyone exclaimed, "Is this the power of the copper arrow?"
