Hearing that Yang Guang was going to trade with the Southern Dynasties, Lu Ben didn't know what he wanted to do for a while, wasn't he afraid of being labeled as a collaborator?

His own trade, because he still has a little to do with the Southern Dynasty, and he is not willing to lose profits, so he is very cautious, but Yang Guang is talking about this matter so boldly and bluntly.

Could it be that this Highness is tempting?

With such a mood, Lu Ben smiled awkwardly and said: "Your Highness, trading with the Southern Dynasties is not a good thing, and law-abiding people like us can't do it." ”

"Okay, then I'll go find someone else, I originally thought that there was a meritorious and money-making thing to do with Lu Jungong, it seems that Lu Jungong is not interested."

Yang Guang got up and was about to leave, Lu Ben looked at Yang Guang's back, and immediately followed after a short thought: "Your Highness, don't worry, I know some ways, but I definitely haven't done these things myself." ”

Although Lu Ben has no ability, but he is really accurate in looking at people, in history, he hugged Yang Jian's thigh at the beginning, and after defeating Gao Gong, he chose to hug Yang Guangguang's leg, and he chose the right person twice, but he hugged Yang Guang's leg early, the time was not mature enough, and he didn't live long enough to be called the emperor of Yang Guang.

Sometimes people don't need to have much ability, and if they choose the right one, they can get out of the mix.

"Lu Jungong, take me to see your glazed workshop, rest assured to follow me, there will be no problems, don't forget that I am still the eunuch of Daxing City, and I must be allowed by my father to do things."

Lu Ben took Yang Guang to their workshop in Xicheng with a smile on his face.

In fact, it is a courtyard, and as soon as I walked in, I felt that the temperature was higher than the outside, and it took high temperature to fire the glass, so the temperature in the workshop was very high all year round.

Walking in, you can see a few workers sweating shirtless, firing glass.

The temperature required for firing glass is very high, the melting point of silica is as high as 1700 °C, but the temperature of most kilns can only reach 1600 °C, which is also the reason why glass is difficult to fire, and the firing temperature of ceramics, even if it is fired at high temperature, only 1200 °C, hard demand conditions, ceramics are smaller than glass.

Therefore, although the craftsmanship of ceramics is also very complicated, we have many skilled craftsmen and have developed a rich ceramic art, and the practicality of ceramics is higher than that of glass in terms of the actual situation in ancient times.

Lu Ben introduced the workshop: "This workshop produces glaze, the technology can be regarded as the best, the technology from the Western Regions is integrated with local technology, and the glaze produced is already the best quality, but the success rate is not high." ”

After a cursory look at the workshop, Yang Guang was quite satisfied, so he said to Lu Ben: "Lu Jungong, I have a way to make the production of glaze easier, and this is the business I want to talk to you." ”

"Oh? Are you sure? ”

"Of course it's true, but the specific plan, after I go to talk to my father, my father will allow me to cooperate with you and make a fortune together."

Looking at the finished workshop, Yang Guang immediately entered the palace and met Yang Jian.

The emperor's face was ruddy at this time, and he looked at the recital that had just returned from the border pass in the study, and when he learned that Yang Guang had asked him to see him, he put the recital aside first.

"Amour, what's going on today?"

"Father, do you know Liuli?"

"Of course I do."

"Glass is valuable, comparable to jade, but now Erchen has found a way to make glass easier to make, and its price will be much lower."

Yang Jian didn't seem interested: "Oh, so what? ”

"Glass translucent, large-scale production, low cost can be installed on the Daxingcheng dwellings instead of windows, light and wind, is the best choice for windows, then can increase the sales value of Daxingcheng dwellings."

Speaking of this, Yang Jian was a little interested, but only slightly, he was very strange how Yang Guang could come to him for such a thing.

Yang Guang then said at this time: "Father, the improvement of the process of glaze will inevitably cause a sharp drop in price, but as long as we keep this secret from now on, the price of glaze is still very high, we can produce glaze and dump it on a large scale to the major cities of the Southern Dynasty, because the transmission of information takes at least a period of time, and in a short period of time, there may be a chance that the cheap glaze produced on a large scale will be exchanged for a large amount of gold and silver wealth in the Southern Dynasties." ”

"Oh?!"

Speaking of this, Yang Jianke came to the spirit.

"The production process of colored glass has been improved, and the cost has dropped significantly, how much can it be reduced?"

"Less than 12 out of 10."

Yang Jian thought about it carefully, if Yang Guang's plan could work, it would be equivalent to earning a lot of wealth in the Southern Dynasty for nothing, and the other would be a bad blow, although there was no fatal blow, but it was quite disgusting.

"Then you can try it, but you should come to me for this matter, right?"

"Sure enough, I can't hide it from my father, in order to win the trust of the merchants of the Southern Dynasty, I may have to bring a small amount of weapons and armor and other items, pretending to be reselling military funds, so as not to make them suspicious, of course, it is a very small number, and at that time, maybe my father will have to cooperate with me to send a Western Regions tribute that was robbed before entering Chang'an, and the announcement of the arrest of the thief."

Yang Jian instantly understood his thoughts, and laughed: "Your idea is quite bad, but there is no harm in it anyway, go ahead." ”

"Thank you, father, there is one more thing, if someone participates in my book to resell military funds, you have to help me speak."

"Go ahead."

Yang Guang received a positive response, returned home, and began to work on improving the glass-making process.

It is said that it is to improve the process, but in fact, it is to add something to reduce the temperature and accelerant required for its melting point.

Sodium carbonate or potassium carbonate, Yang Guang is now extracting potassium carbonate, the raw material is plant ash, the plant ash is soaked in cold water, filtered repeatedly, and finally boiled dry solution to obtain potassium carbonate powder.

I brought the potassium carbonate powder to the workshop and handed it to the craftsmen to try, and this attempt found that the temperature of the glass melting was much lower than before, and I used to want to melt the sand, but I needed to reach the extreme temperature, but now I don't need it, which is no biggest obstacle to the production of glass.

As long as there is this kind of powder, glass can be produced in a steady stream, and the cost is directly sent to the sky and the ground, and Lu Ben is stupid.

Lu Ben didn't get happy: "Your Highness, the production is easy, and the price has dropped." ”

"Lu Jungong, look further, this thing can only be produced by us, and its value is still very high."

Then Yang Guang told Lu Ben about the matter, and Lu Ben looked at Yang Guang in surprise.

"Your Highness, do you really want to do this?"

"Why not? Is it possible for Lu Jungong to help? ”

The things are already known, and the workshop uses his workshop, so now does he want to help? Instead, you have to take a single-plank bridge.

"Your Highness, don't worry, I will fully cooperate and look forward to you."

At this time, Wang Yi, who was not by his side before, trotted over: "Your Highness, you asked me to go to Sun Zhenren and bring the mercury that Sun Zhenren wanted." ”

Yang Guang took the thing, this chemical still has to find Sun Simiao to get the best.

With mercury, you can make a mirror, and the smooth mirror can make people look at their appearance, perfectly surpassing the bronze mirror, which is also the key project that Yang Guang wants to cheat them out of money this time.
