After Fu Bo finished speaking, he took the blueprint and turned around to prepare for the manufacture of the compass. After all, the situation was urgent.

"Hey, Faber, wait!"

Li Zexuan quickly grabbed Uncle Fu and said, "Uncle Fu, the upper part of this compass needs to be covered with a layer of glass, er, it is colored glass, and it is covered with a layer of colored glass, otherwise the magnetic needle will easily fall off and be easily damaged!"

Faber nodded, heard the words, and said, "Well, that's true, but in this way, the cost of a compass is too great!"

Li Zexuan had read countless time-travel novels in his previous life, and he naturally knew that glass was a luxury in ancient times, and the price was very high. He pondered for a moment and said, "Uncle Fu, you can buy some glass from Hushang, first make a compass, and I will come out today. It's urgent."

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

Li Zexuan nodded. He looked out the door and sighed faintly. Then he took out the glass recipe and firing method he had just written on the table and said:

"The compass in the back doesn't need to buy colored glaze from Hu Shang. I have a method for firing glazed glaze. The recipe and detailed steps are written on it. After you explore it, it should be within a day or two. Our workshop can make the colored glaze by ourselves, and it is purer than the colored glaze sold by the Hu merchants! Those Hu merchants have made so much money from the Tang Dynasty over the years by relying on the rough colored glaze manufacturing process. Time to be eliminated!"

"what?"

Uncle Fu couldn't help but exclaimed. It was really too surprising what Li Zexuan said. Since Liuli was introduced to the Central Plains, people have not thought about imitating it in the past, but none of them ended in failure, because just from the appearance, it is fundamental I can't see the ingredients of Liuli, let alone imitating it.

"Master, do you really have a way to burn Liuli?"

"Well, Uncle Fu, try the manufacturing method I wrote you a few times, and you should be able to make it, but you must pay attention to confidentiality. The formula of Liuli should be top secret in the workshop. The fewer people who know it, the better. it is good!"

As long as you know the formula and firing steps of glass, its manufacturing process can't be said to be complicated. Since you have made glass like countless people who have crossed over, how can you be worthy of people if you don't take the opportunity to make a fortune?

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

There is a little story about the person who first discovered glass. According to legend, in the first millennium BC, a European Phoenician merchant ship, loaded with the crystal mineral "natural soda", sailed in Belus on the Mediterranean coast. on the river. The merchant ship ran aground because of the ebb. So the crew went to the beach one after another. Some crew members also carried cauldrons, brought firewood, and used a few pieces of "natural soda" as the supports for the cauldron to cook on the beach.

When the crew finished their meal, the tide began to rise. When they were about to pack up and board the ship to continue sailing, someone suddenly shouted: "Come on, everyone, there is something crystal bright and sparkling on the sand under the pot!"

The crew brought these glittering things to the ship to study them carefully. They found that the shiny things had some quartz sand and melted natural soda stuck to them. It turns out that these sparkling things are the natural soda used to make the pot holder when they cook. Under the action of the flame, the crystals produced by the chemical reaction with the quartz sand on the beach are the earliest glass.

Later, the Phoenicians combined quartz sand and natural soda, and then melted them in a special furnace to make glass balls, which made the Phoenicians a fortune. Around the 4th century, the Romans began to apply glass to doors and windows. By 1291, Italian glass-making technology was very advanced.

"Our country's glass-making technology must not leak out, and all glass-making artisans should be gathered together to produce glass!" In this way, Italian glass artisans were sent to an isolated island to produce glass. You are not allowed to leave this isolated island.

In 1688, a man named Nave invented the process of making large pieces of glass, and since then, glass has become a common object.

Inside the Drunken House.

Seeing his young master's sworn appearance, Uncle Fu knew that the Liuli formula was true. He took the formula and bowed his hands solemnly:

"Master, don't worry, I still know the importance of the old man. The manufacture of colored glass 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 all people who are absolutely loyal to the workshop. As for the first one A compass should be able to be built today!"

Li Zexuan nodded with satisfaction and said, "Well, Uncle Fu, go get busy! I'll be in the workshop in the afternoon. If you have any questions, you can come and ask me at any time."

When Fu Bo heard the words, the solemn expression on his face became even stronger, because Li Zexuan had never stayed in the workshop for such a long time, but he took the initiative to stay today. From this aspect, it can also be seen that Li Zexuan attached great importance to the compass. degree.

"The old man will arrange for craftsmen to make a compass!"

Faber bowed his hands and said goodbye.

inside the house.

Li Tai looked at Li Zexuan curiously and asked, "Mr. can really make glaze? Can you tell Tai about it?"

Li Zexuan rolled his eyes and said angrily, "This is a commercial secret, why should I tell you?"

"…………"

Li Tai was choked for a while, and he said speechlessly: "I won't grab business with you, you are too young

Are you angry? Besides, as a gentleman, preaching, teaching, and solving doubts are what you should do! "

This little fat man really talks about the big truth, Li Zexuan is helpless, he can only give them a brief introduction to the principle of glass manufacturing:

"Actually, the manufacture of colored glaze involves another discipline. I call it "Chemistry". The so-called chemistry can be understood as the study of change. Several things react with each other and can be transformed into other substances. This is what chemistry is all about. The core of the subject, if I have time in the future, I can systematically explain this subject to you. Next, I will briefly talk about the firing principle of Liuli......"

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 would involve many basic problems. In the process of explaining, it is inevitable that some words that they have not heard will jump out, but no one interrupts, and they are all listening intently, because they understand that the knowledge that Li Zexuan is talking about is likely to be used in the Tang Dynasty and even the whole world. It is the only one, and there is no other family. This knowledge is likely to change the entire Tang Dynasty!
