On the ninth day in the officer camp.
Long Yunfeng finished handling the administrative matters that Guo Huai had brought to him and changed into casual clothes. He secretly returned to the Forbidden City with Guo Huai and a few other guards in casual clothes.
Although Long Yunfeng looked like a young master, he only needed to scare a few people.
However, there were many spies from the Shadow Secret Guards secretly distributed around the area.
If anything unexpected happened, they would immediately escort Long Yunfeng away.
After Long Yunfeng and the others returned to the Forbidden City, they headed straight to the west of the city.
"Is everything done?" Long Yunfeng asked.
"Young Master, everything is done. Guo Yuan is in charge of everything.”Guo Huai said.
Long Yunfeng knew Guo Huai's ability very well, so he nodded in satisfaction.
Guo Yuan was Guo Huai's nephew. He was originally working in the Internal Affairs Department and was only a small steward.
But this time, Long Yunfeng had asked him to come over and do something for him. This was because this matter needed to be handed over to a reliable person.
Guo Huai was naturally moved to tears when he heard this.
As the Imperial Eunuch of the Bureau of Rites, he was the emperor's secretary. He could draft official documents for the emperor and execute the country's decrees. He was Long Yunfeng's most loyal servant.
Long Yunfeng naturally had to treat him well.
Guo Huai was a eunuch and had no descendants.
However, there was still some potential among his nephews.
This Guo Yuan was undoubtedly a lucky one.
If he really had the ability, Long Yunfeng wouldn't be stingy and give him a rich life.
Guo Huai was well aware of this, so he specially called his nephew over and gave him a lecture.
After a full hour, Long Yunfeng and the others arrived at a large courtyard in the west of the city.
A young man in his early twenties and a group of craftsmen were already waiting there.
"Your Majesty…"
Seeing Long Yunfeng, Guo Yuan wanted to kneel down but was stopped by Long Yunfeng.
"Just call me Young Master outside.”Long Yunfeng said.
"Yes, Young Master." Guo Yuan quickly replied.
Then, Guo Yuan led them into the courtyard.
In the courtyard, there were a few big pots that were boiling pork fat.
The entire courtyard was filled with the fragrance of oil.
Long Yunfeng walked up to take a look and asked,"Have you prepared all the materials?”
"Young Master, everything is ready. The pig fat will be ready soon. The liquid obtained from soaking the plant ash is also ready.”Guo Yuan replied.
"Alright, let's get ready to begin!" Long Yunfeng nodded.”
That's right, what Long Yunfeng wanted to make was soap.
As an outstanding university student, chemistry was what she was best at.
When oil was added with a solution of soda, it would produce a soap phenomenon. After cooling and solidifying, it would become soap.
Soap had a strong ability to remove dirt. Not only could it be used to wash clothes, but it could also be used for bathing.
However, if it was used for a long time, it would cause some damage to the skin.
If some spices were added to it, it could be made into a simple soap.
The current Great Qin Dynasty did not have such a thing at all.
Once Long Yunfeng was born, he would definitely be sought after by those high-ranking officials, nobles, and young masters.
In fact, if the imperial palace also purchased it and included it as a tribute, the price would continue to rise.
At that time, one could imagine how amazing the profits would be.
The craftsman poured the solution of the plant ash into the pot and began to stir.
“嗞!”
A pungent smell immediately spread out.
However, at this moment, a yellow solid had already appeared in the pot. This was the start of the fermentation reaction.
Not long after, the pot had completely cooled down, leaving behind half a pot of yellow solid.
"Young Master, is this the soap you mentioned?”Guo Yuan didn't think this thing smelled good at all!
"This is soap, not soap. If it's soap, it needs to be improved by adding some spices.”Long Yunfeng chuckled.
The soap was made. Was soap still far away?
"Don't look down on this kind of thing. It doesn't look good, but it has a very strong stain removal ability. It's the best thing to use to wash clothes.”Long Yunfeng took out a bar of soap and wiped it on his hand.
Then, he washed it in clean water. He could feel that the skin on his hands seemed to be much cleaner.
Under Long Yunfeng's instructions, Guo Yuan and Guo Huai both went forward to try it out, and the results were naturally full of praise.
"Young Master, ordinary people might not be able to use this kind of thing. However, there were many people in Great Qin who could afford it.”Guo Yuan said with certainty.
Guo Huai had already told him before that the Emperor's business would be handed over to him to manage, so he was very attentive.
"Yes! "You already know the specific method of making it. If you think of a way to improve it and add some fragrance, it should be enough.”Long Yunfeng said.
"Yes, Young Master, but how should we set the price?”This was the first time he had seen such a thing, so Guo Yuan asked for instructions with some difficulty.
"How much do you think it should be?" Long Yunfeng wasn't sure either. After all, he had not seen Great Qin's prices.
Guo Yuan thought about it carefully and said,""Young Master, it shouldn't be a problem to sell such a large piece of soap for two taels of silver.”
Long Yunfeng couldn't help but twitch his lips. Guo Yuan was only holding a palm-sized bar of soap. Even if some spices were added, the cost wouldn't be too high. Yet, it could be sold for two taels of silver. It was simply too cheap.
It could be said that it was simply a small capital with ten thousand profits!
This piece was enough to feed Great Qin's family of five for half a year.
However, Long Yunfeng didn't have any objections.
In any case, this was not to compete with the people for profit, but to earn the money of those high-ranking officials, nobles, landowners, and merchants.
Rather than squandering their money, it was better to let Long Yunfeng earn it.
Long Yunfeng could at least use this money on the right path.
After that, Long Yunfeng and the others left the courtyard. Guo Huai led them out of the Forbidden City.
The new glass factory was 35 miles north of the Forbidden City, near the Huai River.
The main raw material for making glass was quarts sand, which was also river sand.
This kind of thing was too common, but after it was made into glass, it was undoubtedly a hundred times more valuable.
In fact, Long Yunfeng didn't want to produce glass purely to make money. He wanted to use glass to make things like binoculars and chemical instruments.
Because Long Yunfeng planned to establish a university. What if he didn't have any talents when he entered the industrial revolution?
The chemistry laboratory indeed needed these things to purify the base, and the most important thing was that Long Yunfeng had already gathered all the materials needed to produce glass.
Sand, limestone, and soda ash. These were the conditions to produce soda lime glass. The silica in the sand and soda ash lowered the melting point, and limestone provided calcium. A pure and transparent glass could be born.
These were the materials needed for chemical equipment, beakers, measuring rods, test tubes, and so on. With these equipment, the chemistry laboratory would be fine.
After gathering all the materials, the next step was melting. The formation of molten glass required 1,300 degrees. This temperature was basically similar to that of coke.
Long Yunfeng, the glass-producing staff, had taught them the knowledge of producing glass. After the furnace regenerative chamber was built, the materials could be mixed and thrown in. When the molten glass came out, it would be the time to melt and blow glassware. This could only be done manually.
"Your Highness, this is a glass blowing tube.”
As the materials were being heated, Guo Huai passed him a ceramic tube.
After the molten glass was formed, if one wanted the glass to form a shape, they would need to blow it.
In fact, this was the main point of glass production. Because the temperature of the glass solution was too high, and Long Yunfeng didn't have a heat-resistant alloy pipe, he could only use clay to make a ceramic pipe. After all, he couldn't even produce a seamless steel pipe now.
On both sides of the regenerative chamber, the craftsmen took turns to pull the fan to blow the heat of the coal in the regenerative chamber into the furnace. After waiting for two hours, Xiao Ming asked the craftsmen to open the lid of the furnace.
Suddenly, a wave of heat gushed out from the furnace. The craftsman was so scared that he dodged far away. After calming down, he slowly walked to the front of the furnace.
Then he said,"Your Majesty, the thing inside has melted."”
Long Yunfeng walked up and found that there was indeed a liquid similar to magma inside. This was the liquid glass.
"Give me the blowpipe." Long Yunfeng said to Guo Huai.
Long Yunfeng could impart knowledge to everyone, but the actual operation had to go through practice. No one could become a glass master in one go.
The blowpipe in Guo Huai's hand was about 1.5 meters long, which was the standard length of the modern industry.
Taking the blowpipe, Long Yunfeng picked out a ball of molten glass from the furnace and quickly rolled one end of the molten glass on the rolling plate to make it evenly distributed.
At the same time, Long Yunfeng blew into the glass and quickly blocked the tube with his hand. A bubble quickly appeared in the glass.
Next, he repeatedly softened the glass in the furnace, covered it with molten glass, and finally sent the molten glass into the mold.
As he blew and rolled, the molten glass quickly filled the mold.
After cooling down, a glass bottle with a round bottom appeared. Long Yunfeng sighed. He was just an armchair strategist, his craftsmanship was not good.
When he raised his head in shame, he saw that the eyes of everyone in the room were focused on the glass bottle. Their eyes were filled with disbelief.
"My God, why is this bottle so beautiful?" Guo Huai muttered.“
The other craftsmen were also amazed, and they looked at Long Yunfeng with different expressions. There was nothing that the Emperor didn't know.
"See, this is the art of glassblowing. Of course, the art of glassblowing is extensive and profound. Next, you have to slowly practice the method I taught you and produce all kinds of glassware. "Long Yunfeng said shamelessly.
There were a total of fifty craftsmen in the glass factory. These craftsmen were all selected from the Equipment Division, and Long Yunfeng taught each of them a type of blownware.
Hearing Long Yunfeng's words, Guo Huai was the first to pick up the blowpipe and walk towards the furnace. Although he wasn't a craftsman, Long Yunfeng didn't blame him.
Under Long Yunfeng's guidance, a pile of glassware was quickly made.
This glass, whether it was made into mirrors or windows, would mean a huge fortune!
Soap and glass would also become the two main products of Long Yunfeng's business group in the early stages.
