For the average traveler, can glass be burned overnight? The answer is...... It's hard.

Emperor Taizu, who really crossed and still carried a tool book, didn't toss this stubble, let alone Zhang Shou, who was excellent in physics in the college entrance examination but mediocre in chemistry. He only knew that the glass was burned with quartz sand, but he barely remembered that the raw materials for burning glass seemed to be soda ash, quartz sand, and limestone...... Proportions that really don't remember, chemistry doesn't teach this!

Quartz sand and limestone are good, but soda ash is difficult to prepare in this year, let alone large-scale preparation, so Zhang Shou can only hit the idea of pure natural alkali produced in some salt lakes. Otherwise, the industrial preparation of soda ash, regardless of whether it is the Lubland method or the Soxhlet alkali method, one needs sulfuric acid and the other is ammonia, where can he use chemical reaction to launch these two things?

What's more, although the former claims to be relatively easy, sulfuric acid is highly toxic and dangerous, and it also pollutes the environment, while the latter ...... Ammonia isn't much more dangerous! In this era when the chemical industry is far from mature, he has not even completed the preliminary experimental preparation of highly transparent glass, and he rashly thinks about industrialization, which is going to be a big thing!

He also knows that from ancient times to the present in China, in fact, there have always been a variety of products that claim to be glass in fact, but they are not resistant to high temperatures, so they can only make small ornaments for the homes of dignitaries, and secondly, they ...... Small pieces of glass are not transparent enough, let alone large ones. At the end of the day, the lead-barium glass burned in China from ancient times to the present day and the mainstream soda-lime glass in the West are two different things.

Of course, as for the most mainstream high-borosilicate glass that can withstand high temperatures and is lightweight, the melting temperature is impossible......

Although Zhang Shou really wants to make flat glass and reform the stuffiness and dimness of window paper in these years, the meal must be eaten in one bite, and the road must be walked step by step.

At this moment, Zhang Shou saw a bunch of people excitedly looking at the small piece of transparent glass, and couldn't help but want to sigh. Especially when he saw Yang Zhan, who was so excited that his face was about to deform, he couldn't help but feel that this guy was not prosperous.

But when Yang Zhan rushed over and grabbed him, shouting something with excitement, he was speechless.

"Dr. Zhang, why didn't I meet you earlier! If I had met you earlier, I wouldn't have wasted the things my father left me, and I wouldn't have been considered a ruined son by my own subordinates! I've seen all those glass jars on the market, but the transparency can't compare to the best crystals, but you can use sand to burn glass similar to the best crystals! ”

"Turning decay into magic like this, are you a heavenly craftsman in your last life!"

Zhang Shou was almost choked to death - Tiangong Tianjiang...... He's still a heavenly soldier! But he had just calmed down, and then he heard a voice that was more adoring than Yang Zhan: "Brother Zhang is indeed very powerful, the things he mentioned are all things that I can't think of at all, and many points make people pause." Yang Qigongzi, you are right, Brother Zhang must have been a heavenly craftsman in his last life! ”

I really have a previous life, but I must know that there is a next life now, and I will definitely make science and engineering better back then!

Zhang Shou, who couldn't cry or laugh, faced the countless echoing voices around him, and he said angrily: "Okay, don't say these flattering words, I'm about to fall off goosebumps!" These are not the credit of me alone, but the wisdom of countless wise men throughout the ages. ”

"I'm just strong enough to know a lot about overseas, so I can use the wisdom of those foreign sages."

Speaking of which, it seems that a large number of craftsmen in Constantinople have already fled to Venice these days, right? The famous island of Murano seems to have become a glass center, so I wonder if it has begun to export glass products on a large scale. Since the emperor is already planning to send a ship to the sea, if he can, can he go there and bring back a few more craftsmen?

At least this is to promote cultural exchange between the East and the West...... It would be even better if a few scholars could be abducted and brought back. In this day and age, what famous scholars are there over there? Wait, the all-round Leonardo da Vinci should be born by now, right? How old are you?

Zhang Shou fell into contemplation as he spoke, forgetting that he took the initiative to spread the news today, so the family members all rushed over to see the excitement. When he suddenly came back to his senses and noticed that everyone was looking at him, he laughed.

"If something like glass is made, it will naturally be profitable, and this time I have written down the formula, but the road ahead is still very long."

"For example, how do you make glass thinner and bigger so that you can replace today's window paper, so that people don't have to light up the lights in the house during the day? For example, how do you grasp the characteristics of glass and polish it into a lens that Yang Qilang can see far away and see clearly in front of you? For example, how can glass be made into various utensils instead of today's porcelain? ”

Zhang Shoulian asked a few questions, and when he saw that Yang Zhan immediately fell into contemplation, and so did Guan Qiu and several other craftsmen, he said slowly: "I can use Zhang Yuan's underground secret room to build such a workshop, and I can recruit young craftsmen who are willing to learn all kinds of novel knowledge and then develop these strange things, in the final analysis, it is because of the emperor." ”

"The emperor said that it was for sale, but in fact he gave me this huge Zhang Garden, so now that I have a small achievement, then, how can I hide such a thing in return? Just like the previous spinning wheel and loom drawings, I also plan to dedicate the formula of this glass to the emperor, and then recruit more craftsmen to continue to develop it with Guan Qiu and Yang Qilang. ”

Because Ah Liula Lu Saburo asked, Hua Qi had already quietly covered it up alone, so he could hear Zhang Shou's words clearly. But even so, he couldn't help but pluck out his ears, and for the first time in his life, he wondered if he had heard it wrong.

Although he only glanced at it from a distance, he only listened to the comments and descriptions of the crowd, and he roughly understood what it was. Such a good thing, with Zhang Shou's own ability, it may indeed be difficult to keep exclusive interests, but Zhang Shou is still Zhao Guogong's son-in-law, and there are so many students with different backgrounds, but each with magical powers!

Relying on such backers and arm help, Zhang Shou can make a fortune in a muffled voice! But like the spinning wheel and loom before, people chose to let out the wind to create momentum. And this time is even different from the previous two times, Zhang Shou simply said that he would dedicate such achievements to the emperor while releasing the news!

Could it be that Zhang Shou is ready to quietly do a good job of lecturing in the East Palace, the prince's master, so he doesn't care about such big interests?

And after such a big news was smashed by Shi Potian, Zhang Shou didn't look at the eyes around him that were surprised, regretful, joyful, or incredulous, and said unhurriedly: "Money is such a thing, as long as it is enough, I don't have the ambition to become rich in the world, so instead of working behind closed doors, it is better to invite more people to participate in it and improve it." ”

"I once heard my teacher say two words, in the field of arithmetic, this method of inviting like-minded friends to solve a difficult problem together is called a big tackle, a big battle. And what I'm doing now is another kind of big tackling, the general battle. ”

The next morning, when Ge Yong was picked up in a small sedan chair at the Xuanwu Gate in the north, and then arrived at the Qianqing Palace under the galloping of two sturdy chamberlains, the somewhat dazed old lady heard the emperor repeat Zhang Shou's words, he couldn't help but sneeze twice. Immediately after, under the emperor's blazing gaze, he rubbed his nose angrily.

"When I'm older, I can't help but want to sneeze whenever someone talks about me...... Someone, grab a wad of paper! ”

Seeing a well-behaved little palace maid send a stack of thin papers, Ge Yong coughed dryly, avoided a few steps to blow his nose happily, and when he dropped the few balls of paper and came back, he said indifferently: "That's right, I said it to Chapter Jiu." ”

I fabricated my old man's quotations again, and let my old man take the blame! When you go back, you must find Zhang Shou, this kid, to settle the score!

The emperor saw that Ge Yong would take care of everything without saying a word, although he had long been used to it, he still couldn't help but laugh dumbly: "Teacher, I don't mean to blame Zhang Shou, why do you have to insist that you said it?" That Zhang Shou's ability to burn treasures from the sand can't be taught to him by you, right? ”

"What about me, can't it? I'm an old man who is a pedantic man, so it's not surprising that he understands this, right? Ge Yong saw that the emperor was looking at him with a smile like this, and he said angrily, "Although the official ships of our dynasty have hardly gone to sea in recent years, there are still a lot of merchant ships doing business in various foreign countries in the southeast, northwest, and northwest in private, and of course the books of those foreign sages have also been circulated. ”

"Anyway, I've been studying the "Geometric Original" in recent days, well, I have a deep experience, so I taught nine chapters a little something......"

Although the emperor was much more interested in arithmetic than ordinary ministers because of his study under Ge Yong, even if he was purely self-taught before, coupled with some of Zhang Shou's lecture notes as a reference, he was able to easily tutor the three princes at first, but of course not now. But he is not discussing arithmetic with his teacher at this time, but discussing such a thing as Zhang Shou's "dedication" of glass formula.

Therefore, for Ge Yong's pretending to be confused and deliberately diverting the topic, he had no choice but to cough and interrupt: "Teacher, I don't want to pursue Zhang Shou for anything. I didn't come to you to ask for advice, how should I respond to this matter? ”

"The previous new spinning wheels and looms have gradually spread out, just like Cangzhou, some people benefit, but some people are damaged, but if Zhang Shou can really study high-yield cotton, then the cold people in the world have their clothes, maybe it will not become an empty talk. As for the spinning wheel and the loom, I also gave him a five-grade product, which is actually a reward. ”

"Now that he is about to take up the post of lecturer in the East Palace, I can't add him to another official, right?"

"The official can't reward for the time being, if you want anything, I have already given Zhang Yuan to him, and rewarded him with gold and silver treasures, which is far from enough for him to pay. And if there is something to add to his marriage, it will be too conspicuous...... Alas, he came so and spread the word, and the matter of ordering the Hong family to teach San Lang was directly suppressed, can't he open it up like this a few days later? ”

Knowing what the emperor was having a headache, Ge Yong suddenly smiled: "You have been using nine chapters for so long, you still don't know what this kid wants?" He's the one who wants your recruitment! It's just like he used the words of Yue Shan to recruit talents from all over the world who are proficient in astronomy and arithmetic to gather in the capital, so as to help my old man select talents who can rewrite the calendar......"

"This time, he hopes to use this recipe he dedicated to you to recruit enough skilled craftsmen!"

Seeing the emperor's surprised expression on his face, Ge Yong said with a smile: "He used a group of craftsmen who are young and not very skilled, but they just like to use their brains, and they have come up with so many things, if he really finds a lot of precious talents, what do you think will be the result?" Don't say you haven't heard of what he said. ”

The Emperor suddenly coughed unnaturally again. He can't imagine the prospect of replacing labor and liberating manpower by machines, and he can't imagine it, but for him who is maverick and dares to think and do, Zhang Shou describes that the prospect is very interesting.

And after inheriting the huge wealth passed down from generation to generation by the royal family, he naturally does not need to care about wealth, in his opinion, Zhang Shou, who does not take money in his eyes, is indeed a madman who is obsessed with technology.

"As for you saying that the ninth chapter is a painstaking effort to distract your attention, he will definitely say that how can a dignified gentleman use a woman from the Hong family to share the pressure. You know, because the third prince offered to ask the Hong family to teach him to paint in front of people, your original idea has come to naught. Now the wisdom of the prince is spread outside, all because of a teaching sentence at the emperor's court meeting. ”

was stared at by the teacher so directly, even though the emperor had long passed the age of being afraid of the teacher, he was still a little weak-hearted.

After pondering for a while, he gradually had an idea in his heart, but then he heard a voice outside: "Your Majesty, there is Dr. Zhang's statement." ”

Under Ge Yong's subtle gaze, the emperor could only give a straight face and order to be sent in. When he took the thin notebook and held it in his hand, he hesitated for a moment before opening it. Sure enough, the first half of the article is exactly the same as the news that Hua Qi brought back, Zhang Shou is very generous - or loser to give away the latest glass technology, but the second half ......

Ge Yong was only half right!

Although he felt that the teacher would also miscalculate, the emperor was a little gloating, but it was about himself, and he finally handed over Zhang Shou's notebook directly. Seeing that Ge Yong unceremoniously took it, he opened it to look at it, and then he was amazed while watching, and when he saw the end, the expression on his face froze, but his eyebrows danced, and the emperor was speechless for a while.

"Teacher, seeing you like this, are you supporting Zhang Shou's proposal?"

"Of course!" Ge Yong stroked his beard vividly, but then looked at the emperor with a smile and said, "Some people in the court have been strictly guarding the official ships of the imperial court from going to sea for many years, thinking of monopolizing the sea trade, but Emperor Taizu handed down the master of ceremonies and supervisors who manage the royal industry, and only a small number of people know how much money those sea ships make from the sea every year." ”

Without waiting for the emperor to admit or deny it, the old lady said word by word: "The throne has changed several times, but that fleet has been passed down from generation to generation, which can be regarded as a miracle." It shouldn't be difficult for them to recruit talent in a foreign country, right? ”
