The mirror must be made of flat glass. If Jin Feng had time, it wouldn't be too difficult to spend more time researching it.
But he had been so busy these past few months that he had no time to study or even make glassblowing tools. He just verbally told Lao Tian the principles and steps for making flat glass before leaving Xihewan and asked them to
Go and find out for yourself.
Jin Feng had almost forgotten about it, but Lao Tian came to tell him that he had made a mirror.
This gave Jin Feng a feeling of surprise.
"Let's go and have a look!"
"Sir, can I go?"
Tang Dongdong asked.
The mirror made by Jin Feng was also given to her before, but she accidentally broke it, which made her feel regretful.
"Yes, just don't talk nonsense after you come out."
Except for Wan Yuhong, everyone present was someone Jin Feng absolutely trusted.
As for Wan Yuhong, she is one of the earliest female disciples in Mancang. She has mastered almost all the knowledge in the iron smelting workshop. Jin Feng has accepted her brother as his disciple. There is no point in guarding him anymore, but it will chill people's hearts.
Wan Yuhong also realized this and quickly promised: "Sir, don't worry, I swear by the ancestors of the Wan family that I will not say a word to anyone."
"Well, I believe you!" Jin Feng nodded with a smile and rushed to the glass workshop with a few people.
Although there were only a few people in the entire workshop, it was a lively scene.
In the workshop, some people puffed up their cheeks and blew into the pipes, some were pulling the bellows, and some were preparing molds...
In the middle of winter, everyone was sweating profusely from work.
"Sir, what are they doing?"
This was the first time Tang Dongdong saw such a scene.
"They are blowing glass," Jin Feng replied with a smile.
The best way to make flat glass is to use the "float process". To put it simply, melt the metal tin, make a water tank, and then spread the molten glass into the tin tank, and the molten glass will float on the molten tin.
The glass produced in this way not only has high flatness, but is also easy to mass produce.
Unfortunately, the float glass production line requires too many modern processes. Even if Jin Feng understands the principles, it is almost a dream to build a float production line in Dakang. He can only teach Lao Tian and others to use the most primitive methods.
First, the worker uses a glass blowing rod to pick out a ball of molten glass in the furnace, and blows and shakes it to make a glass tube.
Then the glass tube is heated, cut in the middle, and flattened to become a piece of flat glass.
It sounds simple, but in practice, the steps are extremely complicated.
After countless failures and practice, Lao Tian and the others finally mastered the basic skills.
Seeing Jin Feng come in, all the workers stopped what they were doing and came over to say hello.
"Lao Yuan, go and bring the mirror we made to Mr. Yuan to see!"
Lao Tian shouted to a worker as if he was taking credit.
"Okay!" the worker agreed, ran into the inner room, and carried out a mirror covered with coarse cloth with his companion.
"So big?"
Tang Dongdong tilted his head and looked at it.
The mirror Jin Feng gave her was only the size of a palm, but this mirror was as tall as a person and over half a meter wide.
"This is called a full-length mirror. It can take a look at your whole body."
Jin Feng smiled and said: "Old Yuan, please lift the cloth and let me see if it is clear enough and whether it is out of shape."
"Don't worry, sir, this is the best thing we've done."
Lao Yuan agreed and reached out to lift the coarse cloth.
Although he was mentally prepared, when the coarse cloth was lifted, Tang Dongdong's eyes suddenly widened.
Qin'er's reaction was even greater than that of Tang Dongdong.
The moment the coarse cloth was lifted, she saw a group of people standing in the mirror. She subconsciously stepped in front of the Ninth Princess and immediately pulled out the saber she carried with her.
After seeing clearly that the person in the mirror was them, they stepped aside in embarrassment.
"This...is this too clear?"
Tang Dongdong pointed to the mirror, his face full of surprise.
The Ninth Princess also raised her eyebrows involuntarily.
She finally understood what Jin Feng meant when he said "there's another way to make money."
This mirror is so clear that it cannot be compared to Dakang's bronze mirror.
If it is sent to the capital, there will definitely be many dignitaries willing to buy it at a high price.
Jin Feng was already accustomed to mirrors. He just took a casual look at it, squatted down, pointed at the edge of the mirror and asked, "Old Tian, what's going on?"
Tang Dongdong followed Jin Feng's finger and saw that there was a small raised stain in the corner, which made the mirror surface not so smooth and the things illuminated were slightly out of shape.
"Sir, isn't it just a small speck of mud? Or is it in the corner? If you don't tell me, who will notice it?"
Da Liu and Lao Tian were once neighbors, and the two families have always had a good relationship. They quickly helped Lao Tian speak.
"Da Liu, please stop talking. My husband has told us a long time ago that glass is pure and flawless, and any flaw will be clearly seen. You must be as careful as your hair. We were careless."
Lao Tian said: "Don't worry, sir, I will smash this mirror later and make a new one."
"It won't hurt even if it's smashed. Except for this mud spot, other places are very good."
Jin Feng waved his hand and said: "The mud spot is just on the edge, just cut it off."
Lao Tian and the others only listened to Jin Feng's oral explanation. Although the glass was successfully made, there were several mistakes.
For the next half day, Jin Feng stayed in the glass workshop, guiding Lao Tian and the others to improve the process.
Wan Heming was also very interested in making glass. He made several glass cups by himself, and one person was given one as a gift.
Before leaving, I took a few with me, saying that I would give them to Guan Xiaorou and Tang Xiaobei.
Coming out of the glass workshop, Princess Ninth deliberately lagged a few steps behind and walked side by side with Jin Feng.
Qin'er and Da Liu immediately knew that they had something to say, and they wisely dispersed.
Tang Dongdong also used the excuse that there was something going on at the textile factory and took the first step.
"Sir, can you give me some mirrors?" Ninth Princess asked: "I need them to take care of some things."
"Okay." Jin Feng nodded directly without asking anything.
The Ninth Princess killed so many powerful people at once, and there were too many things that needed to be dealt with.
"One more thing," Ninth Princess hesitated and said, "I have to leave."
"Let's go?" Jin Feng stopped and asked, "Where are you going?"
"A few days ago, Qin'er received a message from brother Xinyao, saying that the angel sent by the father has arrived in Xichuan, and I have to go and receive the order."
Ninth Princess said.
"Accept the order?" Jin Feng's heart skipped a beat: "Did Mr. Qing reveal anything in the letter? What is your father's attitude?"
"My father is the king of a country and the father of this palace. Can't you call him your majesty?"
The Ninth Princess gave Jin Feng an annoyed look.
"No problem," Jin Feng quickly changed his words: "What's Your Majesty's attitude?"
