Otaku Engineer in Great Tang Dynasty Chapter 255: Liu Li!

The genius remembers the address of this site in one second: (Vertex Chinese), the fastest update! No ads! After Fu Bo finished, he took the drawing and turned around to prepare for the compass manufacturing. After all, the situation is urgent.

"Hey, Fubo, wait!"

Li Zexuan quickly grabbed Fu Bo and said, "Fu Bo, the upper part of this compass is also covered with a layer of glass, uh, it is colored glaze. Cover it with a layer of colored glaze, otherwise the magnetic needle will easily fall off and be easily damaged!"

Fuburton nodded when he heard the words, and said: "Well, it is true, but in this way, a compass costs too much!"

Li Zexuan has seen countless journeys in his previous life. Naturally, he knew that glass was a luxury in ancient times, and the price was very high. He pondered for a moment, and said: "Fu Bo, you buy some colored glass from Hushang, first make a compass, I Urgent use today."

"Yes, master, if you make one first, there shouldn't be much problem."

Li Zexuan nodded, he looked out the door and sighed quietly, then he took out the glass recipe and firing method he just wrote from the table and said:

"The compass behind does not need to buy colored glaze from Hushang. I have a method of firing colored glaze here. The recipe and detailed steps are written on it. If you try hard, you should not find one. In two days, our workshop was able to make colored glaze by ourselves, and it was more pure than the kind of colored glaze sold by the Hu merchants! Those Hu merchants made so much money from Datang over the years by relying on the rough glass manufacturing process. It's time for them to be eliminated!"

"What?"

Fu Bo couldn't help but exclaimed. Li Zexuan's words are really too amazing. Since Liuli was spread to the Central Plains, people didn't think about copying in the past, but none of them ended in failure, because of the appearance. Look, you can't see the composition of colored glaze at all, let alone copy it.

"Master, do you really have a way to make colored glaze?"

"Well, I will write you the recipe and firing method of Liuli later. If you try a few more times, Fu Bo, you should be able to make it, but you must keep it secret. The workshop should be top secret, the less people know the better!"

As long as you know the formula and firing steps of the glass, its manufacturing process can't be said to be complicated. Since you have made the glass like countless people through the public, how can you be worthy of people without taking the opportunity to make a fortune?

Actually, the glass manufacturing process in China began in the Western Zhou Dynasty, but the glass made at that time was turbid and far from meeting the requirements of modern glass.

There is a small story about the person who first discovered glass. According to legend, more than a thousand BC, a European Phoenician merchant ship, loaded with crystal mineral "natural soda", sailed along the Mediterranean coast. On the Belus River. The merchant ship ran aground due to the ebb of the sea. So the crew boarded the beach one after another. Some crew members also brought large pots and firewood, and used a few pieces of "natural soda" as a support for the cauldrons to cook on the beach.

The crew finished their meal and the tide started to rise. When they were about to pack up and board the ship to continue sailing, someone suddenly shouted: "Look, everyone, there are some bright, gleaming things on the sand under the pot!" The crew took these shimmering things to Study carefully on board. They found that there was some quartz sand and melted natural soda stuck to these shiny things. It turned out that these shining things were the natural soda they used to make the pot holders when they were cooking. Under the action of the flame, they chemically reacted with the quartz sand on the beach to produce crystals. This is the earliest glass.

Later, the Phoenicians combined quartz sand and natural soda, and then melted them in a special furnace to form glass balls, which made the Phoenicians a fortune. Around the 4th century, the Romans began to apply glass to doors and windows. By 1291, Italy's glass manufacturing technology had been very developed.

"Our country's glass manufacturing technology must not be leaked out. All glass craftsmen must be gathered to produce glass!" In this way, Italian glass craftsmen were sent to produce glass on an isolated island. They are not allowed to leave this isolated island in their lives.

In 1688, a man named Naf invented the process of making large blocks of glass. Since then, glass has become an ordinary object.

Seeing his young master's swearing look, he knew that the Liuli formula was true. He took the formula and said solemnly:

"Don't worry, young master, I still know the importance of the old man. The manufacture of colored glaze will be followed up by the old man himself. There will never be more than five people who know the specific formula, and these people are absolutely loyal to the workshop. As for the first compass, it should be made today!"

Li Zexuan nodded with satisfaction, and said: "Well, Fu Bo, go ahead! I will be at the workshop in the afternoon. If you have any questions, you can come over and ask me at any time."

Fu Bo heard that the solemn expression on his face became even stronger, because Li Zexuan had never been in the workshop for such a long time, but today he took the initiative to stay, and it can be seen from this aspect that Li Zexuan is right The importance of the compass~IndoMTL.com~ Then the old man will arrange the craftsman to make the compass! "

Fubo bid farewell.

Inside the house.

Li Tai looked at Li Zexuan curiously and asked: "Mr. Really knows how to make colored glaze? Can you tell Tai?"

Li Zexuan rolled his eyes and said out of anger: "This is a trade secret, why should I tell you?"

"……………"

Li Tai was choked for a while, he was speechless: "I won't steal business with you, are you too stingy? Besides, as a husband, you are the one who preached, taught, and solved puzzles. It should be done!"

This little fat man really has a set of principles when it comes to principles. Li Zexuan is helpless, he can only give them a brief introduction to the principle of glass manufacturing:

"In fact, the manufacture of colored glaze involves another subject. I call it "Chemistry". The so-called chemistry can be understood as the science of change. Several things react with each other and can change into other substances. This is the core of the subject of chemistry. If I have time in the future, I can tell you about this subject systematically. Next, I will briefly talk about the firing principle of colored glaze..."

Li Zexuan slowly explained to Li Tai and Meng Wenhao the principle of the interaction between the various components in the glass manufacturing process. It must not be too detailed, otherwise it will involve a lot of fundamentals. problem. In the process of explaining, it is inevitable that there will be some words that they have not heard before, but no one interrupted, and they were listening attentively, because they understood that the knowledge Li Zexuan said was probably the only one of Datang. There is no other family, this knowledge is also likely to change the entire Datang!
