Li Yuanjia's confidence is, of course, a mirror.

Perhaps because the porcelain handicraft industry is too developed, glass has not been developed in China, but there are also "imported products" from the West. As for the Westernization, this thing appeared relatively early, and it was quite common in medieval Europe.

But in terms of the times, it is an ornament in Datang.

At least for Li Yuanjia, many ideas, such as building a greenhouse out of glass, are simply unrealistic. After all, when countless people are staring at the output of glass and want to build a bright study for themselves, it is definitely a stupid idea to let him build a vegetable greenhouse with hundreds of glasses.

What a waste!

So Li Yuanjia just gave Chen Mu a limit of fifty pieces of glass, and asked him to build a small greenhouse first-the vegetables grown are probably the kind that can be eaten by Li Yuanjia and Fang Fengzhu in winter.

Naturally, the other glass was taken out and sold.

But no matter how tempting the glass thing is, it's still too limited. And this limitation is mainly due to the quality and price of glass now.

Too crispy, too expensive.

So for at least a decade, glass is destined to be a luxury item for the vast majority of people, and it will severely limit the sales of this thing.

And......

There are also two important factors that also restrict the "money" of glass.

One is naturally Han Cheng's technical level, even if Li Yuanjia spends more money, before there are enough high-quality scientific researchers, the output of glass is probably not too high. Throwing away the cost and the profits left by Li Yuanjia himself, he can give the emperor 100,000 yuan a year, which is the sky.

Another is the "ease of manufacture" of glass!

Don't look at Li Yuanjia's glass workshop in that valley, and they are also very well guarded inside and out, but to be honest, Li Yuanjia actually doesn't have much hope for keeping the secret of glass for a long time.

The birth of glass was originally very simple.

The raw material is sand, and this secret cannot be kept forever...... In fact, whether it is Datang or the Western Regions, there are people who can make glass, but the technology is still very backward, and the transparency and spreadfulness of the glass are too poor.

But the appearance of Han Wangfu glass undoubtedly gave these people a shot of chicken blood!

When these glasses spread in the future, it is natural that someone will put a lot of effort into researching and improving their processes. And driven by huge profits, their level will inevitably advance at a speed that surpasses the times...... With the high price of Li Yuanjia's glass, even if the quality of other people's glass is a little worse, what's wrong?

Cheap is the last word, and there's nothing wrong with it.

So from the beginning, Li Yuanjia didn't really focus on glass. It's just that the transparent nature of this thing can allow the ancient "alchemists" and "alchemists" to see the whole process of chemical reactions, which is too important for the development of chemistry, so no matter what, Li Yuanjia must unremittingly let Han Cheng and them improve, even if they lose money because of it!

The hope of really making a lot of money still lies in the mirror!

One is naturally because mirrors require higher technology, otherwise the French would not have spent so many years and so much money to steal the technology of making mirrors from the Italians; On the other hand, it is naturally because of the particularity of the mirror.

Glass too expensive? Just don't buy it.

But a crystal clear mirror, because it's too expensive, so don't buy it?

Hehe, you talk to those women in the Tang Dynasty and see what they will do! If she is as gentle as Fang Fengzhu, perhaps at most she sheds tears in front of Li Yuanjia and cries to express the grievances in her heart; But if it is an arrogant lord like Gao Yang, if Fang Jun dares to speak like this......

Don't say anything else, I guess I will go up and scratch him first!

Women attach importance to their beauty regardless of age or age, even if they are women at the bottom of society, as long as they have leisure time, who doesn't want to make themselves more beautiful? Especially in the world of the future, mirrors are almost ...... No, almost these two words are not accurate, it should be said that it is a necessity for every woman!

The story of Snow White is the most typical example.

Women in reality don't have a magic mirror, but that doesn't stop them from needing a good mirror that can see their faces. In fact, the best bronze mirror in Chang'an City, the kind of bronze mirror that can't see anything clearly in Li Yuanjia's eyes, has to be sold for about 60 yuan on one side, and the price is scary!

Even so, the ladies still flocked to it.

Because there are very few craftsmen who can make that kind of high-quality copper mirror, there are only two people in the entire Chang'an, and only four mirrors can be made every month, so every time a new product is listed, there will be a battle between the open and the dark......

If it was a glass mirror, how much would the women be willing to spend?

A hundred?

Hehe, a hundred times for you to see!

According to Li Yuanjia's vision, at the beginning, the glass they made was only allowed to be used by the emperor, the concubines of the harem, and the princesses. As for the others, just wait and see!

On the one hand, mirrors are really not easy to make, and mercury is also very toxic, so it is necessary to protect those people in the valley. You must know that there are not many craftsmen who have the technology to make mirrors now, and Li Yuanjia must be willing not to make money to keep them healthy.

On the other hand, of course, it's hunger marketing.

The more you can't get something, the more precious it is, from ancient times to the present, it is a sentence invented by the ancestors.

Just like the glass in Daxing Palace, as long as the court meeting opens, those ministers experience the feeling of brightness and warmth one by one, who is willing to use thick paper or wood to make windows?

And......

The emperors use good things, why can't we use them?

The same is true for the mirror, especially when the concubines of the harem and the princesses of the Tang Dynasty have used this good thing, and the noblewomen who are close to the Han Wangfu can also see their faces clearly, can others bear it?

Why can't you?

Don't be funny......

"Huh? That's right! ”

Thinking about it, Li Yuanjia suddenly raised his eyebrows and remembered a place: "After giving Fengzhu a surprise when the time comes, I can give her a few more small mirrors and let her take them to the club...... Hehe, people who have joined the club can buy mirrors in advance, even if it is more expensive, I am afraid it can attract the attention of countless women......"
