However, the production of collodion is different. Once people know the production method of collodion from beginning to end, the secret recipe of collodion is equivalent to being leaked.
Therefore, it is absolutely impossible for one person to participate in the entire collodion production process from beginning to end. The production process of collodion must be separated, and it is not possible to allow craftsmen from the Ordnance Bureau to participate in the entire production process of collodion.
Han Du planned to put the step of nitrating the guncotton into the Banknote Bureau, where the craftsmen would complete it, and finally send the finished guncotton to the Ordnance Bureau for charging.
Although this process is a little troublesome, it can ensure that the secret of colloid will not be leaked to the greatest extent. Even if all the craftsmen from the Arms Bureau were called in for questioning, they would still not be able to get the secret recipe for guncotton.
The Arms Bureau is larger than the Banknote Bureau, with more buildings, a more detailed division of labor, and more complete places for making various items.
Han Du, surrounded by officials, went through the arms bureau.
When he saw the iron-making furnace, Han Du turned to Heizi and said, "It's up to you to dismantle all these furnaces and build a new blast furnace."
"Okay, sir." Heizi replied calmly. After building a blast furnace with his own hands, Heizi had long lost sight of the iron-making furnaces in front of him.
Not to mention how much iron cannot be smelted at one time, even smelting good steel requires luck. It is completely impossible to directly smelt iron ore into molten steel like a blast furnace.
"Sir!" Zhan Yong stood up immediately and handed over to Han Du.
Han Du looked at him with a smile and asked softly: "What's wrong?"
"Sir, wouldn't it be a pity that this stove should be demolished even though it's in good condition?"
"Zhan Yong." Han Du shouted softly.
Zhan Yong raised his head and stood in front of Han Du without flinching. He absolutely disagrees with your lord, just dismantle these stoves. These stoves were all built at a great cost, and now they were demolished for nothing while they were still in good condition. It made him bleed with heartache.
When Han Du saw Zhan's expression as if his child had been destroyed, he knew what he was thinking. After pondering for a while, he smiled and held his shoulders and said: "Zhan Yong, these things are indeed good. But now they are no longer suitable for use, so naturally they need to be demolished and rebuilt."
"Sir," Zhan Yong looked a little lonely, "I am not trying to refute your face. These things are still in good condition. It would be a pity to tear them down like this."
Before Han Du could speak, the craftsman on the side heard the dispute between the two and intervened.
"Does this gentleman want to dismantle the stove? It cannot be dismantled, sir. It would be a pity to dismantle such a good stove."
Han Du looked at the old craftsman in front of him. His hands were chapped, his face was dark and wrinkled, and he was wearing shabby clothes.
Seeing Han Du looking at the craftsman, Zhan Yong introduced: "This master craftsman is mainly responsible for iron smelting. He speaks straightforwardly. Please don't blame me."
"Of course I won't blame you," Han Du said with a smile, "It's a good thing to have doubts. If you have doubts, it means everyone has thought about it carefully. It doesn't matter if you have doubts. It's better to explain it clearly."
Han Du raised his head and shouted to Heizi: "Heizi, come here and explain to the adults and this master craftsman."
Heizi stood up with a smile and bowed to several people, "I would like to pay my respects to all the adults, and to the master craftsman."
Seeing Heizi's young age, the old craftsman couldn't help but frown, "You are also a craftsman, are you willing to watch such a good stove being demolished?"
"Yes." Heizi nodded.
The old craftsman was so angry that his veins bulged.
Before the old craftsman could speak, Heizi explained: "This old man, I had the same idea as you before. I thought it was a pity that a good stove was dismantled in vain."
"But things are different now." Heizi took out the steel bar that he had shown Han Du from his arms and handed it to the old craftsman. "Although this furnace is good, can it produce such a thing?"
Experts will know if there is one as soon as they take action.
The old craftsman hadn't gotten the steel bar yet, but he just took a look at it and was surprised. Just looking at the color, this steel material is extraordinary. He took it and looked at it carefully, touched it, put it under his nose and smelled it, and finally flicked it up with his fingers.
The sound was clear and sweet, and the old craftsman quickly put it to his ear and listened carefully.
Han Du saw Heizi and the craftsman huddled together and muttered for a while. The old craftsman retreated and said no more.
When Han Du saw Heizi coming, he asked, "Did you convince him?"
Seeing Heizi nodding, Han Du couldn't help but ask: "What did you do? The way I looked at him just now was not easy to talk to."
"The adults don't know something. Craftsmen are judged by their craftsmanship. The younger one's craftsmanship is not bad, so naturally he has nothing to say."
Han Du patted Heizi on the shoulder with satisfaction and said, "Then I'll leave this to you. Don't let me down."
Those who were familiar with Han Du's character just nodded and did not exaggerate or tell lies.
After getting a general understanding, I found that the situation of the Arms Bureau was much better than that of the Treasure Bank Lifting Department. Not only is there sufficient money on the books, but the Ordnance Bureau also has a separate source of raw materials.
Like in the past, if Handu wanted some cotton, he had to pay a high price to buy it. If it were the Ordnance Bureau, this situation would not happen. If you want something, just buy it directly through the channel. Not only is it convenient, it's a lot easier.
Overall, Han Du is very satisfied with the Arms Bureau.
"Sir, what are your instructions next?" Penke asked at the right time.
Next, of course, I want to make preparations.
Han Du said directly: "Well, Heizi, you are responsible for building the blast furnace. You must build the blast furnace as soon as possible." After saying that, he turned to look at Penke.
"Please show me, sir."
Han Du nodded, "Get some craftsmen to come out and divide them into three teams. I am only useful."
Penke nodded in agreement.
...
Just after the Lantern Festival, Jiaofangsi reopened its business, and as soon as it opened, it instantly returned to a prosperous business and made money every day. During the period when Jiaofangsi was closed, the regular customers suddenly felt that there was something lacking in their lives without Jiaofangsi. For this reason, he had no choice but to enter other brothels again.
Some people even thought that Jiaofangsi shop was a big rip-off and vowed never to go there again. But when Jiaofangsi reopened, these people were the first to enter Jiaofangsi.
The correctness of the true fragrance law is fully verified.
Today, the gate of Jiaofangsi is a little different from the past.
Han Du was wearing an earl's uniform and was waiting at the door with Nanny Li.
The guests who came to Jiaofangsi looked at him with suspicion.
"Hey, Master Han is already an earl now? Then we will all call him uncle from now on."
"Did you just know? Master Han's matter about Feng Bo has been spread for a long time."
"I don't know who wants to come and put on such a big show."
"Who knows? However, after seeing Lord Han and Uncle Feng, he is still waiting at the door. The person who comes here must have a high status."
