Hearing that Yang Guang wanted to trade with the Southern Dynasty, Lu Bi didn't know what he wanted to do for a while. Aren't he afraid of being labeled as a collaborator?

His own trade, because he still had some connection with the Southern Dynasty, and he was not willing to lose profits, was very cautious, but Yang Guang spoke about this matter so boldly and straightforwardly.

Could it be that His Highness is testing you?

With such a mood, Lu Ben smiled awkwardly and said: "Your Highness, trading with the Southern Dynasties is not a good thing. People like us who are law-abiding cannot do it."

"Okay, then I'll look for someone else. I originally thought that I could do something meritorious and profitable with Duke Lu, but it seems that Duke Lu is no longer interested."

Yang Guang stood up and was about to leave. Lu Ben looked at Yang Guang's back. After thinking for a short time, he immediately followed: "Your Highness, don't worry, I know some ways, but I definitely did not do these things myself."

Although Lu Ben didn't have much ability, he was really good at judging people. Historically, he hugged Yang Jian's thigh tightly at the beginning. After losing the battle with Gao Jiong, he chose to hug Yang Guang's thigh. He chose the right person both times, but he

It was too early to hug Yang Guang, the time was not mature enough, and he did not live long enough for Yang Guang to become emperor.

Sometimes people don’t need to be very capable. If they make the right choices, they can still get ahead.

"Mr. Lu, please take me to see your glaze workshop. Don't worry, there will be no problems if you follow me. Don't forget that I am still the eunuch of Daxing City. What I do must be done with my father's permission."

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

In fact, it is just a courtyard. As soon as I walked in, I felt that the temperature was higher than outside. Firing glaze requires high temperature, so the temperature in the workshop is very high all year round.

When you walk in, you can see several workers, shirtless and sweaty, firing colored glaze.

The temperature required to fire glass is very high. The melting point of silica is as high as 1700°C. However, the temperature of most kilns can only reach a maximum of 1600°C. This is also the reason why glass is difficult to fire. The firing temperature of ceramics, even

High-temperature firing only uses 1200℃, which requires hard conditions. Ceramics are smaller than glass.

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

Lu Ben introduced the workshop: "This workshop produces colored glaze, and its technology is considered to be the best. The technology passed down from the Western Regions is combined with the local technology, and the colored glaze produced is already of the highest quality, but the success rate is not high."

After taking a cursory look at the workshop, Yang Guang was generally satisfied, so he said to Lu Ben: "Mr. Lu, I have a way to make the production of colored glaze simpler. This is what I want to do with Lu Bi.

The business you discussed."

"Oh? Really?"

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

After seeing the finished workshop, Yang Guang immediately entered the palace and met Yang Jian.

The emperor's face was rosy at this time, and he was looking at the report he had just returned from the border in his study. When he learned that Yang Guang had asked to see him, he put the report aside first.

"Amo, what's going on today?"

"Father, do you know Liuli?"

"Of course I know."

"Liu glide is precious, comparable to jade, but now I've found a way to make it easier, and its price will be much lower."

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

"Glass is light-transmitting and mass-produced. If the cost is low, it can be installed in Daxing City residences instead of windows. It transmits light and blocks wind. It is the best choice for windows. It will then increase the sales value of Daxing City residences."

After saying this, Yang Jian became slightly interested, but only slightly. He was surprised why Yang Guang came to him for such a thing.

Yang Guang continued at this time: "Father, the improvement of colored glaze will inevitably cause the price to drop significantly, but as long as we keep this secret from now on, the current price of colored glaze is still very high, and we can produce colored glaze and dump it on a large scale to the Southern Dynasties.

Since the transmission of information takes at least a period of time in major cities, there may be an opportunity in a short period of time to exchange the cheap colored glaze that will be mass-produced for a large amount of gold and silver wealth in the Southern Dynasties."

"Oh?!"

Speaking of this, Yang Jian became energetic.

"The production process of colored glaze has been improved and the cost has dropped significantly. How low can it be reduced?"

"Less than one-tenth or two."

Yang Jian thought about it carefully and realized that if Yang Guang's plan could work, he would earn a lot of wealth from the Southern Dynasties in vain. Although it was not a fatal blow, it was quite disgusting.

"You can give it a try, but you shouldn't come to me for this matter."

"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 resell military supplies, so as not to make them suspicious. Of course, they will be very few. And maybe my father will still be there by then.

You must cooperate with me in issuing an announcement that the tribute from the Western Regions was robbed before entering Chang'an and the culprits were arrested."

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

"Thank you, Father. One more thing. If anyone wants to help me sell military supplies, you can help me speak."

"Go ahead."

Yang Guang received a positive reply, returned home, and began to improve the glass manufacturing process.

It is said that it is improving the process, but it is actually adding something to reduce the temperature required to lower its melting point, a combustion accelerant.

Sodium carbonate or potassium carbonate, what Yang Guang is extracting now is potassium carbonate. The raw material is plant ash. Soak the plant ash in cold water, filter it repeatedly, and finally boil the solution to dryness to obtain potassium carbonate powder.

I brought potassium carbonate powder to the workshop and gave it to the craftsmen to try. After this attempt, I found that the melting temperature of glass was much lower than before. In the past, if I wanted to melt sand, I needed to reach the extreme temperature, but now I don’t have to. This is very important for the glass.

In terms of production, there is no biggest obstacle.

As long as this kind of powder is available, glass can be continuously produced, and the cost will be directly sent from heaven to underground. People in Luben were dumbfounded.

Lu Ben was not happy: "Your Highness, production has become easier and the price has dropped."

"Mr. Lu, we need to look further. Only we can produce this thing, so its value is still very high."

Then Yang Guang told Lu Ben what happened, and Lu Ben looked at Yang Guang in surprise.

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

"Why not? Can Duke Lu help?"

Everything is already known, the workshop is also his workshop, now does he want to help? Instead, he has to walk a single-plank bridge.

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

At this time, Wang Yi, who was not around before, trotted over and said, "Your Highness, you asked me to bring the mercury that Sun Zhenren asked for."

Yang Guang took the things. It was best to ask Sun Simiao for such chemical supplies.
