"Second Young Master, what's the use of seeing how this thing is?"
The next afternoon, Du Pre came to Du Yuhui with an object and asked, "Glass!"
Did I get the glass out of you all?
”Du Yuhui saw that Du Yu was holding the transparent glass in his hand, and suddenly jumped up and asked, "Glass?"
This was made by the craftsmen when they fired the glass, because it was transparent and had no pattern at all, and it couldn't be used to grind the telescope, if I hadn't gone to the workshop last night and didn't know there was this thing, the second young master, this thing is useful?
”Du Yu looked at Du Yuhui's reaction and asked tentatively: Yes, the demand for telescopes in the Lord Mansion's Mansion is not an ordinary big right, right!
Any ship needs the world's highest magnification telescope, and the pirates who go to sea are still the captain and the first mate, so to speak!
The brothers who went to sea were almost one of them, after all, only then could they observe the distance!
You can't just watch a telescope with a bunch of people taking turns looking at it!
So Du Pre specially got a workshop for the production of colored glass, after all, does the lord's mansion have silver!
And Du Yuhui has never interfered in the research and development of Du Pre, except for doing what he has explained, you can do whatever Du Pre wants!
The results are good!
It's clear!"
How useful is it useless, don't say anything else, do you see this thing, our house is all made of paper paste, if the paper is replaced with glass, this light transmittance is amazing!
Can artisans produce this thing?
I'm talking about the upper scale!
”Du Yuhui asked, "Does this thing have this purpose?"
Oh Neng!
Second young master, you don't know, the Zhuangzi outside the city can be produced, if I hadn't seen the craftsmen and threw this thing away as garbage, I would have picked it up from their so-called garbage heap!
”Du Yu said: "What?
Picked up from the garbage heap?
I think they're too extravagant!
Oh no, reward those masters, and then let them produce abrasives, such as the windows of our house, you see" Du Yuhui began to explain to Du Yu, of course, Du Yuhui actually understood everything, ancient China is likely to have produced glass, but no one knows the value of this thing, and it is normal to throw away waste products, after all, this thing is transparent!
There is the technology to produce glass, as long as you encounter the right material, after all, this is not the need for sand!
And if a batch of raw materials is delivered, there are still raw materials that can produce glass!
In ancient times, we also understood that we would not be so meticulous about the division of things, and we didn't know what minerals or precious metals were contained in these sands.The only problem is that Chinese craftsmen may have also made it, but they don't know the purpose of this thing, or we take the Chinese cabbage seeds that Du Yuhui got back as an example, at that time there were no delicious seasonings, no pork and other things to eat Chinese cabbage, so even if people find that Chinese cabbage can be eaten, try to ask you to eat boiled cabbage every day, is that different from eating wild grass every day!
It's just that there's nothing to do to make it work, so what can people do when they know about it?
Then through natural and man-made disasters, where there are obviously Chinese cabbages, they finally turned into the dust of history!
When the pork seasoning and chili peppers are sufficient, I can't find the Chinese cabbage if I want to find it!
There is no way, many things are because of people's cognition at the time, or it is normal to be delayed, isn't it!
Isn't there such a saying!
Maxima often has, but Bole doesn't last long!
Let's just say that now, even if Du Yuhui takes out a piece of glass, and he doesn't say how to use it, do you let people in this era think about it?
Can't eat, can't use, and it's easy to break and it's also very easy to hold hands, just ask him to stand on the street of Lin'an Mansion and give it away, it is estimated that no one wants to believe it!
This is like a simpler example, the four major inventions such as gunpowder were invented in China!
But where do the Chinese use these things?
Obviously, China's science and technology should be ahead of the world, I don't know how many years!
Just like the shipbuilding industry of the Great Song Dynasty now, the current maritime Silk Road has been recorded in history to Africa and Europe!
But what about the end result!
It was the Europeans who started the real Age of Discovery, more than 200 years later!
And it was the Europeans who turned China into a semi-colonial and semi-feudal society with advanced guns!
Here's the problem, the same thing, you don't know what it's for, and then don't continue to develop it!
It's hard to wait until you're overtaken and then want to catch up!"
Second Young Master means that this thing will be produced in large quantities?"
Du Yu finally figured out Du Yuhui's intentions and asked, "Of course, but let me ask you, can this raw material be supplied?"

”Du Yuhui asked, "Raw materials?"
As soon as the second young master said this, I understood, this glass can be produced, and the key problem is in the batch of raw materials sent, right?
Oops!
The craftsmen still say!
The raw materials sent this time are not good, and the waste materials are too much of this glass, and they can only produce one furnace of glass after firing three furnaces!
And they also said that they can't use Sun Ji's people to send materials in the future!
They also have to change material suppliers!
And the brother who was in charge of contacting Sun Ji also blamed himself, after all, when Sun Ji found him, the price he gave him was half cheaper than the market!
But look now!
Three furnaces out of one furnace is still losing money!
”Du pre said: "Change?
While rewarding the craftsmen, we must also reward the brother!
And let that brother ask Sun Ji, if they are interested, sell the sand and gravel mine they control directly to us!
After all, depending on the situation, they also know that the mine they got can't be sold at a high price, right?
”Du Yuhui said: "I understand the second young master, I will let people contact Sun Ji!"
What about this glass production process?
Do we want to keep it a secret?
”Du Yu asked: "Of course, by the way, these craftsmen are not our brothers, right?"
”Du Yuhui asked: "No, these people turned out to be from the glass workshop!"
Because we have too many telescopes at home, I went to the workshop to order them and then took them back to grind and didn't hurry, so I asked my wife for silver to make my own workshop!
They don't do anything, they just produce glass the size of a telescope lens, and then they start grinding!
Wouldn't that be a hassle-free!
Ao is right, the second young master, this thing is not a secret, so I let them bring an apprentice, after all, there can't be too few people to work!
”Du pre explained: "Brought an apprentice?
So what happened to all of them?
”Du Yuhui asked: "There are many production processes of colored glass, but there is nothing after recording, although the apprentice brothers are not completely independent, but it seems that it is not a big problem for them to produce this glass!"
Because the production of glass is afraid of scrapping, the result is scrapped after the production of glass, if the brothers produce glass I really dare not say that they are apprentices, but I dare not say that the production of glass is not too much of a problem!
”Du Yu said: "Damn, can you still play like this?"
What is not scrapped is glass, and what is produced is glass?
The production process of glass and glass is not so much, and half of the apprentices are drawn out, and while rewarding the craftsmen, don't tell them about the use of glass, just say that they can find that Sun Ji's goods are not good and have made meritorious contributions!
Then secretly assemble the brothers who have been drawn out and go to the castle!
Get them a workshop and let them make glass!
Tell them not to be afraid of failure!
Sun Ji's mine is estimated to be small, otherwise they wouldn't sell sand and gravel at a low price, and our family doesn't have much silver, and we have to get the glass out if we smash it with silver!
When the time comes, Lao Tzu can earn it back with interest!
”Du Yuhui said: "I understand the second young master!
I'll go and command!"
”Du Yu said: "Wait, there is one more thing, on the grounds of throwing garbage, find me a place to put these glass fragments, in the past two days, I have taken the time to go to Zhuangzi outside the city, and Ao asked people to prepare some silver for me!"
I'll see if I can make a few small mirrors out of the silver-plated method!
”Du Yuhui said: "Mirror?
”When Du Yu heard this, he immediately asked: "If you have glass, you have to know the value of this thing, if you can develop a mirror, hehehe!"
Then we'll make a fortune!
”Du Yuhui said: "Ao!
Then I'll go outside the city to prepare first, and when it's all done, I'll fly a pigeon and tell the second young master!
And if there is anything discarded in the future, I will also let the brothers stay, and see if the second young master can turn waste into treasure!

”Du pre-happily left!"
Cognition!
Cognition!
It's like gunpowder is occasionally discovered by Taoist priests when they are refining pills, but it won't be used until thousands of years later!
It's a long way to go!
It's kind of interesting!
No, let Brother Shunzi give orders to the people outside, especially the fleet, in the future, if you go to any territory, you will get me back if you see strange things, even if it is a handful of local soil" After Du Yu left, Du Yuhui said to himself: "The second brother has come to about half of Fanbang so far, and by the way, Li Zhu from Western Xia is also here!"
He also asked about you today, and I said that you are busy during this time, and you have to prepare for the palace exam!
”After entering the hall, Du Yuzhu said: "This guy!
He didn't come to me to gamble with me or something!
”Du Yuhui asked: "You are not specific, he didn't tell me!"
”Du Yuzhu said: "How are they doing?
Is it arrogant or low-key?
”Du Yuhui asked: "When you say this, they seem to be different from before!"
It's a lot more low-key!
Is there a problem with this?
”Du Yuzhu thought for a while and said, "It's okay, I'll just ask casually!"
”Du Yuhui said with a sloppy look:
