"start!"
The iron workshop was steaming with steam. Following Zheng Tu's shout, hot red molten iron rolled down the iron trough from the iron furnace, followed the pouring opening, and entered the sand mold in a steady stream.
Zhao Hong smiled slightly. This rich second generation is still a promising young man with pursuits.
After one sand mold was poured, the next sand mold was poured, and there were as many as twenty or thirty.
"Your Highness, it will take about three to four days to open the mold, clean the gun body, and polish the barrel."
Zheng Tu's face was illuminated by the fire, and his voice was full of confidence.
"Zheng Tu, do you have confidence in the artillery you forged?"
Zhao Hong unconsciously asked about the little fat man.
"Your Highness, I tell the truth, at least 70%!"
"Okay! I just want you to have confidence so that I can have confidence!"
Zhao Hong uttered a "golden sentence" and hurried out of the iron workshop.
What does the saying of later generations say: I want what I think, not what you think.
When everyone came out of the iron workshop, they were all sweating and their heads and faces were steaming.
It was a hot summer day, and the temperature in the iron workshop was extremely high. It could be said that I was sweating profusely, but it was not comfortable.
"Li Tang, write this down and give each blacksmith who smelt iron an extra 3 guan per month. Comrade... the craftsmen are working too hard!"
Zhao Hong's compassion arose spontaneously.
After returning home, these things must be implemented immediately, and I believe the Ministry of Industry will not obstruct it.
Hu Ju, the minister of the Ministry of Industry, is a clever man who is generous to the court. I believe he will not restrict him.
"Your Highness, please look!"
In the work shed outside the iron workshop, Zheng Tu took out an iron ball from the wooden box with difficulty and let Zhao Hong watch it.
"Is this an artillery shell? So smooth?"
Zhao Hong looked at it and then looked at the iron balls in the wooden box. They were all smooth and glowing.
"Your Highness, that's right! This is a 7-pound iron ball. Heat it slowly and then polish it, and the surface will be smooth."
Zheng Tu introduced, Zhao Hong nodded in confusion.
Although he didn't understand these crafts, he also knew that this Zheng Tu was a talent.
Such smooth shells will greatly reduce damage to the gun bore.
"Zheng Tu, are you willing to follow my father-in-law and continue to smelt iron and forge firearms?"
Zhao Hong made a decision immediately.
What he likes most is talent, especially young people. Now that Tian Yi is away, someone is needed to hold the place while casting firearms.
"Your Highness, I am willing!"
Zheng Tu was overjoyed, his face trembling wildly.
"Okay! Now the firearms casting in the iron workshop is under your control. Including the production of artillery and grenades, you have the final say. Although Tian Tiha no longer holds an official position, he is still your boss. In the future, we There's still a lot to do and a long way to go. Do you understand?"
Zhao Hong took the matter seriously and gave his instructions in a serious manner.
Smart people don't need to speak too clearly.
"Thank you for your support, Your Highness! Mr. Tian, please support me more in the future!"
Zheng Tu respectfully saluted Zhao Hong and Tian Yi.
Who doesn't know that Tian Yi is Zhao Hong's confidant and sworn brother. He knew his position and was not arrogant enough to challenge Tian Yi's authority.
"Zheng Tu, we have been living in the village these days. If anything happens, just call us."
It takes four or five days to cool down the cannon blank, plus cleaning and polishing. Shaoxing and Lin'an run in both directions, which really outweighs the gains and losses.
"Your Highness, the gunpowder is almost ready. Look, what should I do?"
Zheng Tu left happily, and Tian Yi asked subconsciously.
Yeah, do something?
Toothbrushes already exist, toothpaste is difficult to make, and ceramics are the quintessence of China; glass, bone china, pendulums, textile looms, and steam engines all seem to be difficult to complete in a short time.
Soap, soap! Saponification reaction!
Zhao Hong's brows immediately relaxed.
In the current situation, soap is short and fast, so you can give it a try without delaying things.
As a college student who graduated from the authentic Pheasant Normal College, and also came from a generation with an explosion of knowledge, he still understands these basic operations.
A large amount of straw is burned to ashes, and one part of plant ash and two parts of water are boiled and steamed. The next day, almost no filtering is required, and it is alkaline water.
Slaked lime is dissolved into an aqueous solution, alkaline water is added, and calcium carbonate precipitates. The above solution is sodium hydroxide solution, commonly known as caustic soda solution.
Heat the caustic soda solution, add vegetable oil and stir, the oil will be fully dissolved to form a solution, which is the saponification reaction.
Soap is produced by adding fine salt to the resulting solution, a process known as salting out.
Just do what you say, do it resolutely, Zhao Hong immediately ordered to go down.
"Tian Yi, let's do this..."
Some things, seemingly ordinary, may be able to promote social development and promote people's employment.
Five days later, Zheng Tu did not come to ask Zhao Hong to see the artillery casting. Instead, Tian Yi came over in a hurry, took Zhao Hong and left.
"Let's go! Go and have a look!"
Zhao Hong was looking forward to it, but followed Tian Yi out of the room without asking.
When we arrived at the yard of Zheng Hao's house, sure enough, the three floors inside and three floors outside were surrounded by villagers who came to watch the excitement.
In the center of the yard, Zheng Hao's wife was washing clothes in a wooden basin, holding an irregular and crooked rectangular cube.
"Look, in just one hour of burning incense, five pieces of clothes were washed and they were all clean! What a good thing!"
Zheng's wife said happily, showing off her washed clothes.
Some villagers came up, washed their hands of their doubts, and were amazed.
"It's really clean! Cleaner than a bathhouse!"
All the villagers went up one after another, washing their hands and marveling at the little things on their hands.
Such clean things are indeed rare.
"Your Highness, what a trick!"
Seeing Zhao Hong appear, all the villagers bowed and made way for him, all respectfully.
This prince of the Song Dynasty, a nobleman from Tianhuang, knew a lot, unlike those dandy boys who were ignorant and incompetent.
Think about it, everyone can smelt iron, let alone something as small as soap.
"Your Highness, can this thing wash your hair?"
Some villagers asked loudly.
"Of course! But it's best to close your eyes. This soap is still a bit irritating, but it won't hurt your hands!"
Zhao Hong pointed at the strange-shaped soap balls that were cut into pieces one by one like a dog chewing, and shouted loudly with a smile on his face:
"Everyone here, take one piece and go back to wash your clothes, wash your hair, and take a bath. Children like to wash their butts. Those who haven't received it will get it next time. Member Zheng will register it for you here!"
"Thank you, Your Highness!"
"Your Highness is benevolent and righteous!"
The villagers were beaming and came forward one after another. Tian Yi and Li Tang poured soap on them one after another.
This prince had some vulgar words, but he sounded close to him.
"Classmate Tian, you are really wasting your resources. Such a good soap, but for you to make it like this, people who don't know would think it's just a piece of shit. It's really yours!"
Zhao Hong looked at Tian Yi and was furious.
"Your Highness, don't worry. Didn't you just try it out? I'll make some molds later and make them into various shapes. I'll make sure they're beautiful and easy to use!"
Tian Yi said with an awkward smile.
"Okay, the appearance should be beautiful, and it is best to be paired with beautiful packaging in iron and wooden boxes, so that you can sell it at a good price. Then let the tabloids publicize it and keep the money you make. Now, you know What should you do?"
Zhao Hong told Tian Yi about his business experience.
Idle time is idle, let Tian Yi continue his promising career in soap making.
"As agreed, I will only do this temporarily, and the money from the sale will also belong to the court. In this way, what you do will be visible to the officials and ministers."
Tian Yi's words were meaningful, and Zhao Hong nodded slightly.
Anyway, Tian Yi and the others were not short of money, and they had made "performances" that were of great benefit to themselves without any harm.
Tian Yi hesitated for a moment and suddenly said:
"Your Highness, soybean oil is too expensive. Can I use lard?"
In comparison, lard is much cheaper than soybean oil.
"sure!"
Zhao Hong laughed and almost said "why not".
The main ingredients of fatty oils and vegetable oils are basically the same. There may be some minor differences, but the essence is the same. They are both raw materials for making soap.
"That's good. Otherwise it would be such a waste!"
Tian Yi nodded, relieved.
"When I go back, I will buy some spices and make soap into soap. Make it look good and make money from wealthy people. Remember, the craft of making soap cannot be spread to anyone without the permission of me, the chief engineer!"
Zhao Hong warned seriously.
spices? Chief engineer?
Tian Yi nodded confusedly.
Soap is a luxury item, and the price of the "soap" cannot be low.
"Your Highness, you have really blinded this villain!"
Xu Sheng used Zhao Hong's mantra and sighed sincerely.
"You have helped a lot in the past few days. When the soap is made, I will give you a few pieces each!"
Zhao Hong laughed.
"Your Highness, we'll talk about the soap later. Let's give some soap to the brothers first."
Li Tang said with a dark smile.
"No pursuit at all!"
Zhao Hong shook his head and looked around.
"Where's Lao Zheng? Why don't you see him come out?"
"Your Highness, Lao Zheng is in the backyard, beating the briquettes!"
Zheng's wife said with a smile
In the backyard of Zheng's house, the sound of "ding-dong" came. Zheng Hao was wearing a sleeveless two-crotch vest and a short crotch-fitting lower body. He was barefoot and holding a coal beater in both hands. He was beating briquettes with his head full of hair. Sweat, I am so happy.
Under the eaves next to him, there were already one or two hundred cylindrical briquettes piled up. It seems that Zheng Hao has been busy for a while.
Li Tang and others gathered around him and did not help. They just stared at Zheng Hao's breathless performance with wide eyes.
"Your Highness, please sit down and drink tea first!"
Zheng Hao was sweating profusely and kept moving. His little daughter quickly came up and obediently made tea for Zhao Hong.
Now, everyone knows Zhao Hong's habit of drinking brewed tea instead of powdered tea.
"Thank you very much!"
It seems that Zheng Hao has a good tutor. The children are all polite and not arrogant at all.
"Your Highness, how many days will it take for this briquette to dry?"
Zheng Hao asked breathlessly while beating briquettes.
"With such good weather, one day is enough! On a normal sunny day, two or three days at most will be enough."
Zhao Hong sat down, looked at the yard, and continued to ask:
"Have you finished that stove?"
"Your Highness, that one is simple and much easier to get than the iron smelting stove. The stove has been dried, bring it over right away!"
Zheng Hao put down the coal lighter and went over to bring two white briquettes.
"Your Highness, please take a look at it. This has been in the sun for a day. Do you think it's OK?"
"Old Zheng, you are very efficient!"
Zhao Hong looked at the briquettes, squeezed them with his hands to make sure they were firm and not falling apart, and nodded lightly.
"It should be fine!"
In just four or five days, not only the coal miner was built, but also the briquettes were available. Now everything is ready except for the Dongfeng coal stove.
"Here comes the coal stove!"
While he was talking, Zheng Hao's second uncle, the blacksmith Zheng Er, excitedly entered the yard carrying a briquette stove.
"let's start."
Zhao Hong nodded slightly and signaled.
"Chop wood and make a fire!"
On the firewood, the briquettes were burned all over and turned red. Zhao Hong picked up the tongs, picked up the briquettes, put them into the briquettes stove, then picked up two pieces and put them on top of each other.
"Your Highness, is this really possible?"
Zheng Hao was doubtful and looked at the stove in front of him.
If it works, this might be a good way to make money.
"Commissioner Zheng, you must believe in me, believe in science, and believe in the wisdom of the people!"
These are the crystallization of technologies that have been tempered and tested in life. How could it not work? .
"Your Highness, you are a great talent, of course I believe in you!"
Zheng Hao was smiling and flattering Zhao Hong.
"Zheng Zheng, just put your heart back in your stomach. In the future, you should count your money carefully! Remember, don't forget my patent fees!"
Zhao Hong smiled slightly, a little embarrassed.
They are all the crystallization of the wisdom of the working people. He is just standing on the shoulders of Zheng, his son, Tian Yi and others.
Thinking of something, Zhao Hong put down his teacup and warned him seriously.
"Executive member Zheng, remember to change the coal. It costs about three or four yuan a day. The seal below can adjust the burning speed. Remember, if you burn it in a house, you must open the window or door, at least leave some space. Otherwise people will die!”
Carbon monoxide poisoning is no joke!
"Also, when selling the stove, be sure to inform everyone who buys the stove about the poisoning precautions. Don't be careless. Otherwise, if you don't talk about it, you may end up in a lawsuit, or you may lose your fortune and go to jail!"
Zhao Hong said with a serious face.
"Don't worry, Your Highness! You must be careful, villain!"
Zhao Hong looked serious, and Zheng Hao also answered seriously.
Houses in the countryside are all closed. Even among the houses in the city, there are almost none that are airtight.
"Commissioner Zheng, don't worry! If you sell it for a year or two, your daughter's dowry will be ready by then!"
Zhao Hong laughed.
Briquettes are convenient and energy-saving, and will definitely become the favorite of thousands of families in the Song Dynasty.
"Your Highness, is it okay to burn it like this, with three or four briquettes a day, without lighting a fire all year round?"
Li Tang looked around the briquette stove carefully, with doubts in his eyes.
"Remove the word "?" of yours, it will definitely work!"
After taking a sip of tea, Zhao Hong spoke slowly.
"It's OK to simmer the fire, but why not briquettes? I'm sure you'll be scared to death!"
How could it not be possible for a product that has been refined and proven by the times for generations to come?
Looking in the direction of Tiefang, Zhao Hong frowned slightly.
This kid Zheng Tu should be making artillery.
