For ordinary people who travel through time, can glass be burned out overnight? The answer is...it's quite difficult.
Emperor Taizu, who traveled through time in person and carried a reference book, didn't bother with this problem, let alone Zhang Shou, who was excellent in physics in the college entrance examination but mediocre in chemistry. He only knew that glass was made of quartz sand.
, but what is the specific proportioning method? He barely remembered that the raw materials for burning glass include soda ash, quartz sand, limestone... I really didn’t remember the proportions. Chemistry doesn’t teach this!
Quartz sand and limestone are fine, but soda ash is difficult to prepare these days, let alone large-scale preparation, so Zhang Shou can only focus on pure trona produced in certain salt lakes. Otherwise, industrial preparation of soda ash
, regardless of whether it is the Lubulan method or the Soxhlet method of making alkali, one requires sulfuric acid and the other requires ammonia. Where can he use chemical reactions to produce these two things?
What's more, although the former is said to be relatively easy, sulfuric acid is highly toxic and dangerous, and it also pollutes the environment. The latter... ammonia is not much more dangerous! In this era when the chemical industry is far from mature, he even
The preliminary experimental preparation of highly transparent glass has not yet been completed. If you think about industrialization rashly, it will cause big trouble!
He also knows that from ancient times to the present, China has actually had various products that are called colored glaze but are actually glass. However, they are not resistant to high temperatures and can only be used to make small ornaments for the homes of dignitaries. Secondly... small pieces of glass
It's not transparent enough, let alone large. Fundamentally, the lead-barium glass produced in China from ancient times to the present and the mainstream soda-lime glass in the West are two completely different things.
Of course, as for the most mainstream high borosilicate glass in later generations that is both high temperature resistant and lightweight, the melting temperature is impossible...
Although Zhang Shou really wanted to make plate glass and reform the stuffy and dim windows of today, he still had to eat one bite at a time and walk one step at a time.
At this moment, Zhang Shou saw a bunch of people passing around the small piece of transparent glass with great excitement, and couldn't help but want to sigh. Especially when he saw Yang Zhan, whose face was almost deformed with excitement, he couldn't help but sigh.
I can't help but wonder if this guy is prospering others but not himself.
But when Yang Zhan rushed over, grabbed him, and shouted something excitedly, he was immediately 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 regarded by my servants as a prodigal who wasted the family property! I've seen
Those glass lamps on the market are not as transparent as the best crystal, but you can actually use sand to make glass that is similar to the best crystal!"
"In this way, you can turn decay into magic. In your previous life, you were indeed a heavenly craftsman!"
Zhang Shou almost choked to death - a heavenly craftsman... He is also a heavenly soldier and a heavenly general! But he had just calmed down, and then he heard a voice that was more admiring than Yang Zhan: "Brother Zhang is indeed very powerful. He mentioned
The things I saw were all things I had never thought of, and many of the suggestions were enlightening. Young Master Yang, you are right, Brother Zhang must have been a heavenly craftsman in his previous life!"
I really have a previous life, but you have to know that there is a next life now, and I will definitely learn science and engineering better in that year!
Zhang Shou, who couldn't laugh or cry, faced the countless echoing voices around him, and said angrily: "Okay, don't say these flattery words, I have goosebumps all over my body! These are not mine alone.
The credit is due to the wisdom of countless sages throughout the ages.”
"I'm just good at knowing a lot about overseas affairs, so I can use the wisdom of those foreign sages."
Speaking of which, it seems that a large number of Constantinople craftsmen have already fled to Venice these days, right? The famous Murano Island seems to have become a glass center, and I don’t know if it has begun to expand on a large scale.
Export glass products. Since the emperor has already planned to send a ship to sea, if possible, can he go there and bring back a few craftsmen?
At least this is also to promote cultural exchanges between the East and the West... It would be more ideal if we could kidnap a few scholars back. In this day and age, are there any famous scholars there? Wait, the all-rounder Leonardo da Vinci should be born by now
Are you there? How old are you?
Zhang Shou fell into deep thought as he spoke. He actually forgot that he was the one who took the initiative to spread the news today, so everyone in his family had just swarmed over to watch the fun. When he suddenly came to his senses, he found that everyone was looking at him eagerly.
, and then he laughed.
"If something like glass is made, it will naturally bring huge profits. Although I have recorded the formula this time, the road ahead is still long."
"For example, how to make the glass thinner and larger so that it can replace the current window paper so that people can stay indoors during the day without lighting up? For example, how to master the properties of glass and grind it into the kind of glass that Yang Qilang has?
Telescope, and lenses that can clearly see the objects in front of you? For example, how to make glass into various utensils to replace today's porcelain? "
Zhang Shoulian asked a few questions and saw that Yang Zhan immediately fell into deep thought, as did Guan Qiu and other craftsmen. He said slowly: "I can use Zhang Yuan's underground secret room to build such a workshop, and I can recruit everyone."
The young craftsmen who are willing to learn all kinds of novel knowledge and then develop all kinds of strange things are ultimately because of the Emperor."
"The emperor said he was selling it, but in fact he gave me this huge Zhangyuan. So now that I have achieved a small amount of success, how can I hide something like this in return? Just like the spinning wheel and the previous one.
Just like the loom drawings, I also plan to present the glass formula to the emperor, and then recruit more craftsmen to continue developing it with Guan Qiu and Yang Qilang."
Because Ah Liu pulled Lu Sanlang to ask questions, Hua Qi had quietly come over to cover him up early, so he heard Zhang Shou's words clearly. But even so, he couldn't help but pick his ears. For the first time in his life,
For the first time I wondered if I had heard wrongly.
Although he only glanced at it from a distance, he could roughly figure out what it was just by listening to people's comments and descriptions. With such a good thing, it might be difficult for Zhang Shou to maintain his exclusive interest based on his own ability.
But Zhang Shou is also the son-in-law of Duke Zhao, and there are a large number of students from different backgrounds, but each has magical powers!
With such a backer and help, Zhang Shou can make a fortune silently! But like the spinning wheel and loom before, he chose to make a lot of noise to build momentum. And this time is different from the previous two times. Zhang Shou simply made the news
At the same time as the news spread, he clearly stated that he would dedicate such achievements to the emperor!
Is it possible that Zhang Shou was prepared to quietly do the lectures and readings in the East Palace and be the prince's master, so he didn't care about such a huge benefit?
After such a shocking news, Zhang Shou did not look at the eyes around him that were either surprised, regretful, happy, or disbelieving, and said unhurriedly: "As long as money is enough, it will be enough." , I don’t have the ambition to be rich in the world, so instead of working behind closed doors, it’s better to invite more people to participate and improve it.”
"I once heard a teacher say two words. In the field of arithmetic, this method of inviting like-minded friends to jointly solve a difficult problem is called a big attack or a big battle. And what I am doing now is another big problem. Attack key points and fight in a big battle."
The next morning, when Ge Yong was picked up in a small sedan at the Xuanwu Gate in the north, and then arrived at the Qianqing Palace with two strong servants, the somewhat dazed old master heard the emperor repeating Zhang Shou's words. At that moment, he couldn't help sneezing twice in a row. Then, under the emperor's bright eyes, he rubbed his nose angrily.
"As I get older, I can't help but sneeze whenever someone talks to me... Someone, bring me a bunch of fine paper!"
Seeing a well-behaved little maid presenting a wad of fine paper, Ge Yong coughed dryly, took a few steps away to blow his nose, and when he dropped the wad of paper and came back again, he said calmly: "That's right, I told Jiuzhang."
You fabricated my old man's quotations again and again, and made me take the blame! I will definitely settle the score with this guy Zhang Shou later!
The emperor saw Ge Yong taking care of everything without saying a word. Although he was used to it, he still couldn't help laughing: "Teacher, I don't mean to blame Zhang Shou. Why do you insist that it was you who said that? That Zhang Shou’s ability to burn treasures from sand couldn’t have been taught to him by you, right?”
"So what if it's me? Isn't it possible? I'm an educated man, so it's not surprising that I know this, right?" Ge Yong saw the emperor looking at him with such a smile, and then he said angrily, "Although I have been courting the emperor all these years The official ships almost no longer go to sea, but privately there are still many merchant ships going to various foreign countries in the southeast, northwest and northwest to do business. Of course, the books of those foreign sages have also been circulated."
"Anyway, I have been studying "Elements of Geometry" recently. Well, I have a deep understanding of it, so I taught a little bit in Chapter Nine..."
Although the emperor was much more interested in arithmetic than ordinary ministers because he studied under Ge Yong, he was able to easily tutor the third prince at first even if he had purely self-study before and with some of Zhang Shou's lectures as a reference. No way. But he was not discussing arithmetic with his teacher at the moment, but discussing Zhang Shou's "presentation" of the glass formula.
Therefore, in response to Ge Yong's pretending to be confused and deliberately changing the topic, he had no choice but to cough and interrupt: "Teacher, I don't want to pursue Zhang Shou for anything. I came to you, this is not Do you want to ask me how I should respond to this matter?"
"The previous new spinning wheels and looms have now gradually spread. Just like Cangzhou, some people will benefit and others will suffer. But if Zhang Shou can really develop high-yielding cotton, then the cold people in the world will have something to wear. Maybe it won't turn into empty talk. As for the spinning wheel and the loom, I just gave him a fifth grade, which is actually a small reward."
"Now that he is about to take office as a lecturer in the East Palace, I can't give him another official position, right?"
"The official can't reward him for the time being. As for things, I have already given him Zhang Yuan. Rewarding him with gold, silver, wealth, and silk is far from enough for his efforts. And if I add anything more to his marriage, it will be too conspicuous.
...Sigh, he did something like this and spread it out. The matter of my ordering the Hong family to teach Sanlang was immediately suppressed. Can't he open up like this again a few days later?"
Understanding what the emperor was having a headache for, Ge Yong suddenly laughed: "You have been using Jiuzhang for so long, and you still don't know what this kid wants? He wants your recruitment order! Just like when he used Yue Shan
In a word, it’s like recruiting talents from all over the world who are proficient in astronomy and calculus to gather in the capital, so as to help me select talents who can reset the calendar..."
"This time, he hopes to use the formula he dedicated to you to recruit enough skilled craftsmen!"
Seeing the surprised expression on the emperor's face just because of this, Ge Yong said with a half-smile: "He used a group of young craftsmen who are not very skilled in craftsmanship and just like to use their brains to create so many gadgets."
, if he really finds out a lot of valuable 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. Machines replaced labor and liberated manpower. He could not imagine this prospect, and there was no way to imagine it. But for him, who was maverick and dared to think and do, what Zhang Shou described
It's a very interesting prospect.
After inheriting the huge wealth passed down from generation to generation by the royal family, he naturally does not need to care about wealth. It seems that Zhang Shou, who does not take money seriously, is indeed a madman obsessed with technology.
"As for you, Jiuzhang has failed your efforts to divert attention. He will definitely say, how can a dignified gentleman use a woman from the Hong family to share the pressure? You know, because the third prince took the initiative to invite the Hong family in front of others.
Your original idea of coming to teach him painting has come to nothing. Nowadays, the reason why the prince is a wise man is all because of a sentence he taught the Analects of Confucius in the emperor's court meeting."
Being stared at by the teacher with half a smile, even though the emperor had long passed the age of being afraid of the teacher, he still felt a little guilty.
After pondering for a moment, he gradually came up with an idea, but then he heard a voice from outside: "Your Majesty, I have a petition from Dr. Zhang."
Under Ge Yong's subtle gaze, the emperor could only order with a straight face to send it in. When he took the thin memorial book and held it in his hand, he still hesitated for a moment before opening it. Sure enough, the first half of the chapter and Hua Qi
The news he brought back was exactly the same. Zhang Shou was very generous - or rather prodigal - in giving up the latest glass technology, but the second half...
Ge Yong was only half right!
Although he felt that the teacher would also miscalculate, and the emperor was a little gloating about his misfortune, but it concerned him, he finally handed Zhang Shou's memorial directly. Seeing that Ge Yong took it unceremoniously, he opened it and read it, and then he clicked his tongue in surprise while reading it.
, and when he saw the end, the expression on his face froze, but for a moment his eyebrows lit up, and the emperor was speechless for a while.
"Teacher, looking at you like this, do you support Zhang Shou's proposal?"
"Of course!" Ge Yong stroked his beard in a lively manner, but then he looked at the emperor with a half-smile and said, "Some people in the court have been strictly guarding against official ships going to sea over the years, trying to monopolize sea trade, but Taizu
It was passed down from the emperor to the ceremonial supervisor who was in charge of the royal estate. Only a handful of people know how much money those ships make from the sea every year."
Without waiting for the emperor to admit or deny, the old master said word for word: "The throne has changed several times, but the fleet has been passed down from generation to generation miraculously. It can be regarded as a miracle. Let them recruit talents from foreign countries.
