Li Yuanjia still knows something about the manufacturing method of glass.
However, this kind of understanding is limited to knowing that glass is made of quartz sand...that is, melted sand. Of course, this common sense will be known to anyone who likes to read online novels in the future. But Li Yuanjia knows more at least, for example, he
We know that the melting point of quartz sand is 1,750 degrees, which cannot be achieved with ancient technology, so fluxes must be used, which are trona such as plant ash, and then some limestone must be added during smelting.
stabilizer.
And then……
Apart from these written things, Li Yuanjia's eyesight turned black.
How to melt these materials, what is the specific ratio of various materials, and what is the blowing method that should have appeared in this era? Han Wang, who wants to make glass, said that it should be a chemistry major or an engineering major.
Yes? It has nothing to do with medical students anyway. We are only responsible for using glass and don’t know how to make it.
Fortunately, just like paper making, there are also glass craftsmen these days.
Although there are very few, and the technology is much inferior to that of the Persians, this is Chang'an City after all, and it is the center of the entire Tang Dynasty, so as long as you are willing to spend money and time, you can always find it.
As long as we can find people, things will be easy to handle.
When many people hear about glass, they always subconsciously think that it is a very modern thing. In fact, this kind of gadget has appeared thousands of years ago. The Phoenicians used a few pieces of glass to cook on the beach.
Natural soda was used as a stand, and as I was walking, I found some shiny things.
Whether in the West or China, the history of glass manufacturing can be traced back to long ago BC.
The legendary glassblowing technology also appeared very early. However, due to the war, one is that the speed of technological progress is very slow, and the other is that it is easily lost. Therefore, it was only after the Venetians improved the glass manufacturing technology that it was
If you can make money, just put all the workers on a small island to avoid the outflow of technology...
However, no matter how complicated the technology is, it is still technology from thousands of years ago, and King Han is very confident in creating glass.
To put it bluntly, he has money and status!
It is absolutely difficult for ordinary people in this world to learn the technology of making colored glaze and try to improve it, because if you think about it, you will know that this will definitely require full-time manpower and huge amounts of money to support it.
But the nobles who have this ability are not interested in this kind of thing.
Wouldn't it be easier for them to buy with money?
But Li Yuanjia is different. He has money and can afford the continuous investment in a "glass research laboratory"; he also has status, and as long as he is willing, he can naturally find craftsmen who can make glass; of course, more importantly, he has the ability to transcend the times.
The experience of the "scientific research concept" papermaking workshop can be directly transferred to it.
Therefore, in Li Yuanjia's mind, making glass should not be difficult. If he could organize a team and have a leader like Wang Pu, just like improving papermaking and inventing movable type printing, he believed that it would not take long
You can create crystal clear glass!
However……
At this time, Li Yuanjia still didn't know how big of a pit his natural taking for granted would drag him into, and how many years he would be trapped...
…
In the summer of the tenth year of Zhenguan, the death of Empress Changsun plunged the entire city of Chang'an into silence.
Compared with the formal feeling when the emperor passed away last year, the city was full of simplicity and all the people were mourning. Although the situation was much smaller this time after the death of the queen, the ministers around the emperor knew very well that Li Shimin was the real one this time.
Sad.
Several times when he went to court, Li Yuanjia could feel the emperor's trance.
He didn't know how to evaluate this.
From a man's point of view, Li Shimin is undoubtedly very admirable. Especially as an emperor, no matter how many beauties he favored, his love for his eldest grandson was very strong and deep. This is really true in Chinese history.
It's rare; but if you look at it from an emperor's perspective, it's a bit unacceptable that Li Shimin neglected political affairs because of his sadness. At least Li Yuanjia was particularly excited when he heard the officials reporting the progress and death toll of the plague.
I can't stand Li Shimin's indifferent attitude!
But this time, even Wei Zheng didn't dare to say anything.
After all, they are just some ordinary people. In the long history of China, the life and death of these people are often the most insignificant. It was only after arriving in this era that Li Yuanjia understood that the so-called loving the people like sons is all relative! Just like Zhenguan
This ten-year epidemic will probably be remembered in history books as "diseases in Guan Nei, Hedong, and many people died", just a few strokes...
Throughout the second half of the tenth year of Zhenguan, everyone in the court seemed to be in a very strange atmosphere.
However, in the tenth year of Zhenguan, many things happened throughout the Tang Dynasty, such as the rotation of the princes of the Tang Dynasty; for example, Li Shimin blamed the ministers, saying that officials of third rank and above neglected the King of Wei, despised his own son, and tried to further advance the imperial power.
; For example, in the military system, there are 634 mansions in the world, of which 261 are within the customs; for example, Sun Delun, a descendant of Confucius, was conferred the title of Blessing Saint Marquis; another example is that following the emperor's wishes, Chu Suiliang, who was promoted to an admonishment official, suggested that the prince should become a cabinet minister
Staying in the capital temporarily opened the road for the third generation of the Tang Dynasty to seize the throne...
Following the original trajectory of history, Datang is still moving forward step by step.
Li Yuanjia, this little butterfly, seems to have no impact on this era at all. Apart from changing his own history and being left in Chang'an by Li Shimin, only the rich and powerful can afford coal stoves and tables and chairs. Thirteen Incense
It is a luxury item that ordinary people can’t even see a penny of!
Perhaps the only important thing is to have Quyuanli appear decades or more than a hundred years earlier.
As a time traveler, Li Yuanjia himself seemed to have no problem with this dull and boring life. After he found two glaze craftsmen, brought them into his residence, and built a small workshop for them, he started working honestly every morning.
After going to court, he returned home and wrote books steadily, paying attention to the renovation of the palace and the technical improvements of the craftsmen, and then watched with joy as Li Zhong and others grew up day by day.
At the beginning of November, the eldest grandson was buried in Zhaoling.
In December, Murong Nuohebo, the king of Tuyuhun River Headquarters, came to court. Zhu Jubo and Gantang sent envoys to pay tribute, and Xiao Ba, one of the prime ministers of the Tang Dynasty, became the governor of Qizhou.
In any case, Li Yuanjia finally had his first New Year's Day meeting since returning to Chang'an.
This is the most solemn annual gathering.
This also means that the tenth year of Zhenguan has become a thing of the past, and the eleventh year of Zhenguan has arrived quietly...
