Chapter 69 Scales

Although Wang Lang explained the shortcomings of this copper saw to them, but such a sharp tool was destroyed by Wang Lang, people's hearts seemed to be bleeding.

Huo knelt down and stroked the copper saw with a very painful expression, and said with a choked voice, "Lang, we finally carried these stones back to make this saw. Even if it is not durable, it is still much better than the stone axe. Why? Is it just smashed like that?"

Wang Lang looked at Huo who was about to cry, and he couldn't laugh or cry, and said: "This one is broken, let's remelt it and make it again. This copper is not broken like a stone, and it is useless at all."

"That's right! Why am I so stupid? Tin is like this. After it's broken, just remelt it and make a new one. This thing called copper is definitely fine." Wang Lang's reminder immediately got excited, holding the A copper saw broken in two must be thrown into the furnace for remelting.

Seeing the excited Huo, Wang Lang pulled him back and said, "Don't look at what time it is now, it will have to be tomorrow if you want to re-smelt it, not to mention that you can't smelt it directly like this, I'm inside Add tin and don’t separate it out, and the thing made again is still the same as the current one.”

Looking at the pitch-black night around him, Huo realized that it was already night. He smiled awkwardly and said, "I'm so excited."

Bark patted Huo on the shoulder, and said with a smile: "You see, you are so anxious, when the leader makes a mistake, can the leader you can think of not think of it?"

Huo glared at the winking bark, scratched his head, and said, "Why mix copper and tin?"

Wang Lang explained: "Simply tin and copper are too soft and have limited uses, while copper and tin mixed together can be extremely hard, but how much copper and tin are put have a great impact on the things made. I now I still don't know how to mix to get the satisfactory effect, so I can only keep trying."

Wang Lang explained a lot, and people only understood that the two metals were more powerful when smelted together. As for the ratio, it sounded like a bible to their ears, but they didn't bother to ask Wang Lang about such a complicated matter. Let Wang Lang solve it, and he only needs to contribute when the time comes.

After seeing the sharpness of copperware, Huo was so excited that he didn't sleep well all night. He got up early the next morning when everyone else was still asleep. Sleeping soundly, it’s not easy to wake them up, so I can only walk back and forth in the tribe very agitatedly, going to check the charcoal kiln for a while, and checking the copper ore for a while, it seems that as long as I don’t pay attention, these things will It's like it's missing.

Half an hour later, people gradually woke up, and seeing Huo squatting motionless next to the copper stove, they were very puzzled, wondering what the hell he was doing.

Yawning, Bark walked behind the fire, patted him on the shoulder, and said, "What are you doing staring at the stove for getting up so early!"

Due to his over-concentration, Huo was taken aback by the sudden slap. He turned around and saw that people were already awake. He regained his energy and ignored the yawning bark. He walked up to Wang Lang and said, "Lang, let's start!" Let's make a saw!"

Wang Lang stroked his growling stomach, looked at Huo helplessly and said, "Everyone is hungry, why worry, let alone, copper smelting is not something that can be completed quickly, if you don't have physical strength, how can you do it?"

Hearing Wang Lang talking about eating, Huo's stomach also growled, and he smiled awkwardly, knowing that he was a little too impatient.

After a simple meal, Wang Lang asked someone to smash the broken copper saw into small pieces with a stone, put the smashed pieces into a crucible and burn them on the fire.

Due to the difference in the melting points of tin and copper, it didn't take long for a white liquid to separate from the fragments. After all the fragments stopped flowing out of the white liquid, Wang Lang used chopsticks to pinch the unmelted copper out.

Although this method cannot separate all the tin in the bronze, the tribe now has relatively little tin. Even if only a small amount of tin is separated, it is still a very important material.

In order to determine the ratio of copper to tin, Wang Lang planned to make a simple scale.

Anyone who has studied physics will understand the lever principle of the scale. Wang Lang asked someone to find a straight branch thicker than a thumb, and used it as a scale beam. He chose a stone the size of an egg and tied it with a rope to serve as a weight.

In the next few days, Wang Lang made all the copper ore he brought back into copper bricks. These copper bricks were all about the same size and weight. Wang Lang decided to set the weight of this copper brick at one catty.

With the scales of these copper bricks, the scales can be determined. It took Wang Lang a day to determine the fixed plate, Xinghe and other scales. Looking at the crude scale in his hand, there must be errors, but these errors are very important to the upcoming scale. It doesn't matter much what you do.

With the weighing tool, the ratio of copper to tin can be determined next. Although Wang Lang did not know the optimal ratio of copper to tin for bronze ware, Wang Lang knew that it would definitely not be a 1:1 ratio, so Wang Lang weighed four ratios For different copper and tin, the raw materials of two taels of copper and one tael of tin to five taels of copper and one tael of tin are stacked next to the copper furnace.

These days, although other people couldn't understand what Wang Lang was doing, they now knew that all the preparations were done.

Lin Huo waited with torment for several days, and now he was finally able to refine those magical things again. Huo said excitedly: "Lang, can we start?"

Wang Lang nodded and said, "Okay, let's start with the small ones!"

Huo responded excitedly, and put the raw materials of copper, tin and one into the copper furnace.

Due to the lack of raw materials, in less than an hour, a red liquid flowed out along the groove. I was very enthusiastic about this, and immediately put the prepared container under the groove, and poured the received solution into the nail mold.

In half a day, people smelted all the four different proportions of copper and tin.

At night, Wang Lang asked people to take out the mold in the puddle. After smashing the clay mold, four yellow copper nails appeared in front of people.

Because the nails made last time were not ready to be used, Wang Lang had people smash them all, so people looked at the four nails in front of them and didn't know what to do.

"Boss, how do you use this thing!" Kong Yi asked.

Wang Lang said: "This thing is used to connect wood, but it's useless now, I just use it to test the effect of copper."

Wang Lang determined that the way to make the bronze effect is to smash it with stones to determine the one with good hardness and strength.
