Among all the workshops belonging to the Han Wangfu, the glass workshop is certainly not the most important.

Although according to some theories of later generations, the reason why Chinese chemistry did not develop later, or even did not start, was attributed by some people to the opposition of glass and porcelain - in one opinion, because of the developed porcelain technology, the demand for glassware in Chinese was much lower, so in the end no effort was made on it.

The birth of glass plays an extremely important role in chemistry.

To put it bluntly, transparent glassware allows people to directly observe the occurrence of chemical reactions, which in turn arouses people's interest and begins to strengthen the exploration of this field. The existence of porcelain, in a sense, greatly reduced the importance of glass, and also led to the fact that ancient Chinese scientists were not able to observe this......

At the beginning, Li Yuanjia really felt that it made sense.

But after thinking about it carefully, he felt that this statement was not very reliable. After all, chemistry needs the help of glass containers, but what about other aspects?

Several basic types of modern science, mathematics and physics, don't need glass?

Therefore, in Li Yuanjia's heart, if you want to talk about importance, glass is naturally far inferior to Arabia...... Ahem, Indian numerals, at best, are about the same as improved papermaking, and the prohibitively expensive printing of movable type.

And, it's just about the same.

But what I have to say is that among all the industries of Han Wangfu, the "money" scene is the most vast and the most important, but it must be glass!

Hanwang paper is easy to sell? In short supply?

That's right, no matter how many pieces of white paper they make, they are sold out on the day they arrive in Chang'an, and even if they are now constantly expanding the papermaking workshop and constantly training new papermaking craftsmen, the white paper made in the next three years will always be in short supply, and it is still far from the "money scene" of glass!

After all, there are many people who can make paper.

Although Hanwang paper is now the top white paper in Datang, so that many bigwigs in the DPRK and China do not use it now, but because of Li Yuanjia's deliberate control, even if the cost is constantly decreasing, the price is always high.

The reason is very simple, don't worry about selling!

The scale of the paper workshops outside the city is constantly expanding, the number of craftsmen is increasing, and the process is constantly improving and improving, and the end result is that the production of white paper continues to grow. But don't forget, as the fame of this kind of blank paper grows, there is much more to meet than meets the needs of Chang'an alone.

There are also a lot of powerful and rich people in Luoyang, the second largest city, can they use it?

Taiyuan, the starting place of the old Li family, as well as the patriarchs and descendants of those gate valve families, who lacks this little money to buy paper?

Not to mention the businessmen and rich people all over the world, who likes to be vassally elegant, or someone at home reads, who doesn't want to use the white paper of Xinhua Bookstore, which has recently become famous? Not to mention that if they knew that the real source of this blank paper was Han Wangfu, wouldn't they desperately want to use it a little?

That is, now the news has not spread too much, and only the people on the top floor know that Xinhua Bookstore is Han Wangfu's, otherwise......

But from beginning to end, Li Yuanjia didn't think about keeping it secret or anything.

It's just because now people who have the ability know that this paper is made by Han Wangfu, and they don't want to mix it, and they can't even find the door if they can't do it...... At the beginning of the year, I found Xinhua Bookstore without opening my eyes, and I had the courage to create the idea of paper craftsmanship, but I was tossed miserably by Han Lucheng. If it weren't for the fact that the king has a low-key temperament and is unwilling to have more rights and wrongs, Han Lucheng, who is extremely arrogant to the outside world, can make the mastermind behind the scenes directly ruined!

To put it bluntly, the main reason why the papermaking process of Han Wangfu has not been spread is that Han Lucheng and Wang Pu have worked hard.

If someone really asks Li Yuanjia for it, he can't really send it out directly!

This thing, the more people who know it, the better.

It's not that he Li Yuanjia really has such noble sentiments, and he doesn't care about the more and more huge income every year, but compared to the benefits brought by the improvement of papermaking to Datang, that money or something is simply not worth mentioning.

There is also movable type printing, if someone is willing to learn, Li Yuanjia will not hesitate to transfer it, even if it is because of this, you can paste part of the money!

Nothing else, it's a complete loss of money, and it still has to lose a lifetime, the kind that is hundreds of thousands of yuan!

Anyway, no matter how you think about it, Li Yuanjia can't think of the possibility of making money by movable type printing, just the funds needed to make hundreds of thousands of alloy movable type, how many books do you have to print to earn back?

!

It's a pity that Li Yuanjia himself knows that it is easy to pass on the craft of papermaking, after all, it can make money, but movable type printing is such a thing......

So if you think about it, you can only come by himself!

And in this case, it is extremely important to make money.

Although there are a lot of items in Han Wangfu every year, and Li Yuanjia's own life is not luxurious, plus a few years ago, because of the enough votes of Thirteen Xianglao, so he can still hold on, but every time he thinks about the cost of coke, cement, movable type printing, and more new technologies in the future, Li Yuanjia can't give up the glass thing more and more.

There is no doubt that this is a gold mine!

Ordinary glass in the 21st century is not valuable, but many giants can still be born in various special applications, such as the one that makes automotive glass, or the one that makes mobile phone glass, which is very famous. In ancient times, even the most ordinary, even low-quality glass in the eyes of future people was the most valuable asset!

Consider Venice, Italy, where an island was dedicated to glassworkers to keep this precious technology from spreading. And the later French also spent a huge price to break the monopoly of the Italians.

Because it's so valuable!

Relying on this technology of the rotten streets of later generations, how many gold coins did the Venetians earn?

Although there is a saying that the existence of porcelain has suppressed the development of glass, Li Yuanjia does not believe it at all now, because he does not believe that anyone will continue to use paper windows after using glass windows, and will continue to endure the dim light in winter!

It is easy to go from thrift to luxury, and it is difficult to go from luxury to thrift!

So he walked around the valley and found that everything was as he expected, the new craftsman...... No, it should be said that the apprentices' technology is progressing very quickly, and when there are already many people who can make good quality glass, Li Yuanjia's face has already shown a satisfied smile.

The increase in production is undoubtedly the most joyful.

Because this means that they can meet the needs of the palace at a faster speed, and when the emperor's side is almost done, the opportunity for him to make a lot of money in the Han Wangfu is coming......
