Chapter 280 Home Craftsman
Judging from the composition, what Guan Zunban said is true, Nanyangwei's steam engine is indeed turning!

Although it is only spinning, it is easy to blow up because the air pressure is not known, and there is no pressure relief structure, no condensation, no water filling pump, and it still cannot be put into use.

But Chen Mu thinks he is great, and Guan Yuangu is also great.

In the fifth year of Longqing in this world, maybe it was the winter of the fourth year of Longqing?Ming Dynasty craftsman Guan Yuangu made the first steam engine.

Even if it can't be put into use, Guan Yuangu took the first step from scratch, which is the most difficult part for Chen Mu. He knows that the steam engine converts steam heat energy into mechanical energy, but he doesn't know how to convert it.

Now the most difficult step has been done by Guan Yuangu.

All that remains is to move forward.

On the day when he saw the composition, Chen Mu wrote a letter and sent someone to quickly send it to Nanyang, asking Bai Yuanjie to send troops to take care of Guan Yuangu's hard work, and asked Guan Yuangu the next step.

Although he can't make it, he has eyes that can see what's wrong.

For example, the pistons are not compact enough. This kind of problem requires him to find a better drilling machine in the north to solve it; Chen Mu’s task for Guan Yuangu is to take the simple steam engine a step further, condense the steam back, and think about how to add water to the pump. Operation, how to test internal pressure and relieve pressure properly.

Chen Mu knew that this was beyond the ability of ancient craftsmen.

They have extremely strong professional skills and unique whimsy, but after making a steam engine and making some small improvements that don't make much progress, they have reached the maximum they can achieve, and the questions Chen Mu asked are no longer these It can be solved.

But Chen Mu was able to give the direction of the problem. If they were asked to look for it themselves, of course they would not be able to find it. Let alone no solution, even if there was a solution, they would not be able to think of where the problem was, let alone start.However, after Chen Mu gave the most correct direction for these things, the most difficult problems have been solved.

"A lot of tests, to determine the specifications and water volume of the steam furnace, you can embed a crystal in the casing to see the water volume, and test the water consumption time. Add a few valves, the water volume is lower than the valve, and the external valve is opened to divert water and release part of the pressure in the furnace. "

This is what Chen Mu wrote in the letter, and at the same time, he also sent Guan Yuangu a composition of the siphon principle for him to experiment in Nanyang.

He is not in a hurry. He said that he will not use the steam engine for three to five years or even his whole life, but as long as this thing comes out, as long as it can be put into practical use and open to the whole world, it will bring about earth-shaking changes.

Damn, I'm really tired!
Watching the riders walk away, Chen Mu sighed heavily. He also wanted to set up a school, teaching students some physics and chemistry in the name of studying things, and created a lot of scientists. Maybe they can build airplanes now — But where does he know physical chemistry?
The physics he knows is that the cannonball can break the bricks of the city.

The chemistry he knows is that when the gunpowder is ignited, the cannonball can be pushed out.

It can be seen from this that Chen Mu has extremely high attainments in physics. As far as the cannon pops out of the chamber and smashes two hundred objects, no one can do better than him if he is given a cannon; but what about chemistry?He doesn't know as much as an ancient craftsman.

His craftsmen are removing silver and depositing gold.

Because Chen Mu wanted to let the emperor see the results sooner, he asked Shen Jiang for silver in a hurry.Although the Shen family is a wealthy businessman, it is not easy to collect tens of thousands of silver taels in a short while, so they collected a lot of gold and silver from the market.

Simple silver taels were no longer enough, and more than 8000 taels of gold with poor quality were also sent to Chen Mu.

It wasn't that Shen Jiang sincerely cheated Chen Mu. In an era where morality is above all else, merchants cannot achieve great things without integrity.When the gold and silver were delivered, Shen Jiang said that the amount of silver was sufficient, but more than 8000 taels of gold could only be worth 5000 taels of silver.

The old gold and silver craftsman commanded more than 40 apprentices to forge the gold into flat pieces, and then cut them into small pieces one by one, wrapped them in soil, poured them into a crucible, mixed them with stone powder and melted them, and the gold of Zize could flow out.

Chen Mu didn't wear official robes, but was wrapped in sable fur and stood aside, watching with great interest, and asked the craftsman, "What is that stone powder?"

"It looks like you are very popular with General Zhenshuo, and if you don't come back to do this drudgery, it's okay to tell you."

The craftsman probably only thought that he was Wu Bian who walked around the general's mansion, chewing betel nuts, grabbed the stone powder with hands that were often dry and cracked and embedded with black stains that could not be cleaned, and showed it to Chen Mu, and said with a smile: "This is borax, there is this And soil, burning gold can absorb the silver inside, and your general's gold can flow out to recast gold bars and ingots."

"Suck the silver away?"

"Yes, silver. This fake gold can only be mixed with silver. Now the silver is in the soil. When the gold is separated, put a little lead in a crucible and the silver will come out again."

The old craftsman was very pleased with himself, and said: "With this method, the gold and silver are all there!"

Chen Mu nodded his head slowly, with just the right admiration in his eyes, which is indeed very wise, and then the old craftsman said with emotion: "Your general is really rich, some of this gold is full of color, and some of it is not good enough, and the old man is not as good as you are." I've never seen so much gold and silver... I heard that the General's Mansion wants to recruit artisans, is it true?"

Chen Mu secretly laughed in his heart, and sure enough, it had already spread.

He wants to recruit another batch of home craftsmen from these craftsmen who came to serve labor. This time, the best craftsmen from the South China Sea and the North are ordered by the Ministry of Industry to come here for only one year, and another batch will be changed after one year. Come here, because it is labor, so no one will pay them, and what the Xuanfu needs to provide is only to provide them with food and lodging.

Chen Mu raised a group of people in order to pick out some of them and give them a monthly salary to work with him for a long time.

"Of course it is true, but it is very difficult to become a general's craftsman. Only the best craftsmen can be selected. You will have more than 1000 people, and the general will only recruit [-] or [-]." Chen Mu smiled and raised his eyebrows. : "A monthly salary of one liang of silver, and a stone of rice noodles for each of the family's apprentices. I usually work in the Military Weapons Bureau, and there is a place in the Xuanfu to provide food."

"If the general has a special order to work, you will be given two cents of silver for tea and wine for each working hour, and there will be rewards of varying degrees if you make it."

The remuneration is absolutely generous for the artisan group. All the rewards are added together, and combined with Xuanfu's food management, it is equivalent to a monthly net income of three or four taels, which is even higher than their own income from opening a workshop.

The old craftsman chewed two mouthfuls of betel nuts, and said in a Huguang accent: "These are the best craftsmen! If you are a general's home craftsman, can you be exempted from class craftsmen and labor?"

"That's definitely exempt!" Chen Mu laughed loudly. He knew that this is what the craftsmen are most concerned about. These best craftsmen can only come to work in Xuanfu because they have no money to pay the shift money of the Ministry of Industry. He waved his hand and said, "General Zhenshuo will give you the court's labor money!"

"When will we recruit people?" The old craftsman glanced back at the busy construction site, and said anxiously, "I have four sons, all of whom have this skill. The general will definitely not lose money by accepting me!"

"Don't worry, when everyone comes, we will notify you at that time."

Chen Mu left happily, two years, two years to recruit a camp of craftsmen, what else in the world can't be made by him!
