Liu Yuanshan thought a lot and thought far!

The more I thought about it, the more I felt that the pace of development had slowed down. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

With the book of God in hand, there is no shortage of various technologies in the development of the most primitive industries, but there is a lack of raw materials, a lack of associations between various industries, and the most important thing is that there are few people!

In ancient times, society developed industrial talents, and they could not recruit them, so they could only cultivate them slowly.

It's a slow and painful process.

Liu Yuanshan had read many time-traveling novels in his previous life, and many mentally handicapped protagonists ran to ancient times, and they could casually make all kinds of modern weapons, but now he has no shortage of technology in his hands, but it is difficult to move an inch on the road of industry.

It seems that YY kills people!

Liu Yuanshan thought about it very late for a while, and then fell asleep in a daze.

When I woke up early the next morning, my spirit was a little bad, but Liu Yuanshan was too busy, and many times he didn't have time to sleep at all.

That's it, after he got up, washed up, and had breakfast, the morning training of the subordinates had been completed.

Liu Yuanshan called everyone over, gathered together, and said, "This is the end of today's training, there are other things to do. He took out a few pages of drawings from his bosom, looked at them, and said, "Your task today is to build two more furnaces. ”

Liu Yuanshan took out the drawings in his hand, showed them to everyone one by one, and explained how the furnace was built, how big it was, what materials were used, and so on.

The material, naturally, is sintered bricks, and as for the size, it is exactly in accordance with the hints given in the sacred book.

The two stoves are slightly different.

The first furnace was similar to the previous furnace, except that the combustion chamber below was larger, with slightly less space for sintering above and a higher location.

The first furnace was made of three layers of thick red brick, two chambers, and a vault at the top.

The second stove is a bit more complicated.

The second furnace is circular from the outside, about two meters high, the furnace is divided into three chambers, the lowest chamber is the same as the steel-making chamber, which is used for fire, the middle chamber is the largest, around the whole furnace body in front and back left and right open four holes, the holes are circular vaults, leading to the second chamber in the middle; The top cavern is the smallest, but the top cavern and the lower two caverns are connected by a small square hole in the middle, which can communicate the temperature, and behind the upper cavern, there is also a space through the preheating passage, which looks like a tunnel.

These two furnaces are Liu Yuanshan's magic weapon for making another essential artifact for crossing!

This kind of thing is glass.

The raw material source of glass is very extensive, generally speaking, the main material is quartz sand, there are rivers in Fangxian County, the most important thing is quartz sand, in addition to quartz sand, the rest of the materials are soda ash and limestone.

At present, quartz sand is not a problem, limestone is also something that can be obtained everywhere, but the source of soda ash is a little troublesome, soda ash is not absent in the Ming Dynasty, but the use of this kind of thing is very little in ancient times, maybe only those alchemists and weird witch doctors will use it, so this thing cannot be purchased in large quantities.

However, it's not impossible to have soda ash, anyway, you can use plant ash instead!

From the book of gods, the main process of firing glass is basically just a few moments: one is to mix the three raw materials of quartz sand, limestone and plant ash in a certain proportion, and fire this thing into a molten state in the first sintering furnace, and after cooling, it will become a lumpy object, and the impurities and vitreous will be separated.

In this step, a large amount of impurities are removed, the vitreous agglomeration containing small amounts of impurities is knocked out, and the vitreous can then be placed in a second furnace for further firing.

The second processing was a bit cumbersome.

In order to avoid soot pollution in the process of ignition, the glass should be placed in a special container to close and be fired to a molten state to obtain the glass solution, and then skilled workers can blow the glass solution into various shapes with iron pipes.

For example, cups of various shapes.

Of course, Liu Yuanshan has no skilled workers here, and everything has to be guided by slow practice. That's not a problem at all.

There's one problem: containers.

That is, the crucible that holds the glass solution during the combustion process!

The high-temperature crucible doesn't cost a lot of money to buy in modern society, but in ancient society, it is relatively difficult to obtain, at least, Liu Yuanshan doesn't have it on hand.

But it doesn't matter, Liu Yuanshan doesn't have it, the Ming Dynasty still has it!

Modern high-temperature crucibles are good, but if they don't have them, you can find something else instead: ceramic crucibles.

The principle and materials of this kind of thing are not complicated, and the difficulty lies in the production process, Liu Yuanshan believes that it can be found in the Ming Dynasty.

However, this is a later story, now the glass furnace is covered and air-dried, and once the crucible is found, small-scale production trial work can be carried out, which can save the most time.

Liu Yuanshan's purpose in making glass is not as simple as making a profit, nor is it to make those exquisite and clear cups to win people's hearts.

How much of a use glass can be made is known only to modern people. It can be used to make cups, and it can be silver-plated and turned into mirrors! It can bring endless wealth to Liu Yuanshan.

But that's not the most important thing!

Most importantly, this thing is the basis of optical instruments.

He can make convex and concave lenses, which can then be further processed into telescopes, astronomical telescopes, microscopes, measuring instruments, and much more, etc.

This is Liu Yuanshan's ultimate goal.

After a busy morning, he finally taught the construction method of the two blast furnaces to his subordinates, Liu Yuanshan suddenly felt sleepy, patted his mouth and handed over the drawings in his hand to one, and said: "You look at the construction, I will go to make up for sleep, I didn't sleep well last night." ”

patted his mouth and walked to the door, just happened to meet his mother Liu and sister Liu Yanran, who were holding a lot of gifts in their hands, and were about to go down the mountain with two maids.

"Mother, sister, where are you going?" Liu Yuanshan asked with a smile.

"Alas...... This ruthless bandit and bandit is thundering and thundering! Liu said and made a gesture of beating people, and said: "San Lang, you don't know, the Zhao family is the Zhao family who proposed to you before, and their family ......."

Liu said this, his eyes were red.

Liu Yuanshan only felt that the sky was dark, and suddenly the sky was thundering......

Mom, it's good not to curse your son like this, your old man doesn't know yet, the people of the Zhao family are your son......

"San Lang, you're busy!" Liu Yanran took Liu's hand and said: "I heard that the Zhao family was wiped out, Zhao Zhenzhen's girl didn't die, she fainted from crying yesterday, people from outside the village went to visit, and my mother is going too!" So I went with her to see it. ”

"Ah...... Really? Liu Yuanshan pretended to be surprised, chatted with his mother and sister for a while, and said a little sadly: "You guys go first, I'll go back and see, I don't see you when you look down." ”

Sending Liu and Yanran away, he walked to the room alone and was sleepy. She opened the small door of the inner room and was about to climb into bed to sleep, but the sight before her surprised her, and she no longer felt sleepy.

Xue Huan, it's back! (To be continued.) )
