Chapter Seventy-Five: Smelting Copper Ore
Chapter Seventy-FiveAfter smelting copper ore to calm Chang'er, Ye Feng went around, and he couldn't think of a way to smelt copper ore for a few days, which made him upset, and he breathed outside to relieve his boredom.
With his hands on his back, he unconsciously arrived at the pottery kiln. So much pottery was burned, and several clansmen in charge of burning pottery were very handy with it. Even under the guidance of Ye Feng, the pottery kiln was improved, and it was much larger than the kiln that Ye Feng made before. The efficiency is much higher than that of the previous pottery kiln, but the failure rate is greatly reduced, so a lot of pottery is fired every day.
Ye Feng felt the boiling heat wave from the pottery kiln, and had an idea, the temperature of firing pottery is 800-1000 °C, if the pottery kiln is improved again, and the high heat of coal is added, so that the temperature of firing reaches the melting point of copper, then does it mean that copper ore can be successfully smelted?
Just do it, Ye Feng summoned the few people who fired pottery, and no one dared to say one in the tribe on how to control the temperature in the kiln, so they had a lot of say in how to improve the pottery kiln.
After hearing that they might be involved in the smelting of metals, they were so excited that they stopped burning pottery and expressed their opinions, and the pottery kiln, which had not stopped since the kiln was opened, entered a rare "dormancy".
For a few days and nights, Ye Feng ate and slept with these people, discussing the melting furnace with their mouths open and closed. After their unremitting efforts, a plan was finally finalized, and a small experimental melting pot was built.
Today is an important day, the world's first artificially refined metal will be born in the humble little furnace of the Xingyue Tribe. The whole tribe knew the value of metal, so the people looked forward to it, craned their necks and looked at the little stove, all to witness this miraculous moment.
Ye Feng and they took turns fanning the wind in the stove, although the heat wave was rolling and sweating and raining, they were afraid of any omission, so they all gritted their teeth and persevered.
After Ye Feng drank a bamboo tube of water, the clansmen next to him immediately made up for it, and he didn't know how much water he had drunk. Ye Feng wiped the sweat from his head and looked at where the sun was, it was almost two o'clock in the afternoon, and the fire had been lit since four o'clock in the morning, almost six hours had passed, and it was time to bake.
He commanded the crowd to bring in molds made of clay, including saws, axes, arrowheads, spearheads, and a sledgehammer. As for swords, due to the soft texture of copper, these thinner slashing weapons are very easy to break, so they have to be done.
Ye Feng brought over a strange pottery, only to see that this pottery was no different from other pottery pots. It's just a little deeper, with an extra spout on the rim that facilitates the flow of liquid, and a square ear on the back that resembles the handle of a cup, and if you enlarge it, the whole pottery looks like a large cup.
Ye Feng put this "cup" at the mouth of the kiln, put those molds one by one, and waited for the kiln to open.
One of the clansmen picked up a wooden stick and carefully poked open the clay at the mouth of the cave, and a stream of red water flowed down the pottery channel of the peach into the "cup".
"Look! That red thing is the copper water that Ye Feng said! A clansman said triumphantly, as if it was a great thing to know about it.
"How do you know?" Unconvinced, one of the masters retorted.
"Ye Feng said it in class!"
"Really, why didn't I hear that?"
"You're embarrassed to say that you fall asleep every time you are in class"
"Anyway, can you eat that thing?" The person who says this kind of thing will definitely be an authentic foodie in the future generations.
"You're stupid, look at the smoke, it's hot when you look at it!"
Ye Feng didn't pay attention to the noisy crowd, and after confirming that there was no copper water in the furnace, he picked up a square wooden stick fired with pottery, and slowly inserted one end into the handle of the "cup" filled with red copper water.
At this time, the role of this handle was also reflected, and I saw Ye Feng insert the handle of the water cup into the middle of the pottery stick, and a clansman who fired pottery tacitly held the end stretched out. At the beginning, Ye Feng planned to make the pottery sticks and handles round, but he thought that they might tumble, so he made them square.
"Up!" Ye Feng shouted, and the two of them carried the hot copper water slowly and walked towards the mold that had been placed over there.
The mold of the first axe, in order to save copper water, Ye Feng only made an axe body, and the axe handle was made of wood, which was full of wood all over the mountains, which was cheaper than anything else.
The two of them pointed the spout at the mouth of the mold, carefully turned the clay stick, and with the tilt of the cup, the hot copper water condensed into a thin thread, which was slowly poured into the mold. When the mold was full, the two of them didn't pay attention, and the red bucket of water overflowed from it, but fortunately, they reacted in time, and quickly raised the mouth of the water cup to stop an accident from continuing to expand.
The clansman looked at Ye Feng at a loss with a clay stick, Ye Feng was also helpless about it, and pouted at another mold, saying, "Leave it alone, let's go pour another one." ”
It was smooth to come down, and the two of them poured out the saw, hammer, and spearhead one by one. But because there was too little water in the bucket, just such a cup, the arrows did not pour out.
Ye Feng was not disappointed, this was only experimental in nature, only a small part of the ore was smelted, and the most important thing now was to see if those tools could succeed.
The tools solidified smoothly, but they were still hot, Ye Feng asked someone to bring a basin of water from a clay pot, carefully buckle the axe from the mold with a thin wooden stick, cover it with soaked animal skins, and quickly throw it into the basin.
As soon as the axe was thrown into the water, it made a burst of explosions, and the calm cool water seemed to be boiling and bubbling with bubbles, and the bursts of steaming water vapor seemed to bubble up, and then it stopped after a while.
Ye Feng fished out the axe from the water and wiped it clean with the black charcoal on the wet animal skin, and the golden axe body appeared.
"Hahaha! Not bad! If you succeeded, you went back to find a coarse stone and grinded away the spilled copper. Ye Feng grinned and said to the stunned few people: "What are you still doing in a daze, quickly throw those into the water to cool down, pay attention, you must wrap it in animal skins." ”
"Oooh!" Several people reacted, they didn't expect that the original worthless stone had been turned into this shape after this time, not to mention other effects, the golden appearance had blinded their eyes, and completely convinced them.
Ye Feng played with the axe in his hand, he was overjoyed, the edge of the blade was very blunt, and he still had to sharpen it well and use it.
"Ye Feng, what is this?" A clansman took the saw and asked Ye Feng.
Ye Feng didn't say anything, took the saw, found a wooden stick, and pulled it slowly.
The eyes of the crowd widened suddenly, and they were dumbfounded as they looked at the neat fracture, and the tiny sawdust on the ground, and the speed at such a rapid pace.
