In the winter of Chang'an City, even Xungui's family has no fresh vegetables to eat.

By the time this meal was eaten, Li Kuan had a relatively full understanding of the situation of the dining table in the northern winter of the Tang Dynasty.

"Xuan Ce, how is the production of glass mirrors now?"

When I first heard about the existence of greenhouses in the Han Dynasty, there was no more in the Tang Dynasty.

Li Kuan felt that even if it was for his food to be delicious, he had to toss something.

Think about it, in the winter, the nobles are tired of eating meat, and it feels absolutely good to come to the courgette (that is, the cucumber now) at this time.

Even if it is not sold for money, it is more impressive than giving precious calligraphy and paintings, right?

So Li Kuan naturally wants to think about how to engage in greenhouse planting.

Ideally, the film must be used, and it can be exchanged in the system, but when it comes out, I can't explain to anyone where it came from.

Therefore, consider using glass to build, but it is more reliable.

"The production of glass mirrors has completely increased, and the mirror workshop has also become independent from the porcelain workshop, and now there are more than a foot wide mirrors for sale in the treasure cabinet."

The glass mirror is the most profitable thing in the Chu Palace, and every time he talks about it, Wang Xuance can't help but smile.

"Can a larger full-length mirror be made now?"

"Lord Wang, a larger mirror can be made, but the mirror surface is not flat enough, and the figure reflected is not small and clear. And when the mirror is bigger, the mirror can only be made thicker, and when the mirror is thick, it is even more difficult to produce qualified products. ”

For this situation, Wang Xuance was not very worried.

In his opinion, the current mirror is enough, and even in order to maintain the price from falling, it has reached the edge of deliberately controlling production.

"Tomorrow we'll go to the Mirror Workshop."

From Wang Xuance's words, Li Kuan has already felt the feasibility of making a greenhouse.

The requirements for the flatness of the glass are naturally very high, but if they are used to build a greenhouse, the requirements are much lower, as long as they can transmit light.

……

The porcelain workshop of the Chu Wangfu was originally a small and inconspicuous workshop.

Since Li Kuan made a glass mirror here, he immediately became the focus of the noble family of Chang'an City.

In order to keep the secret recipe for making glass mirrors, the Chu Wangfu stationed nearly 100 guards here.

"Lord Wang! This is Chen Dali, and his level of firing glass is the highest. ”

"Steward Wang has won the award, and this little skill of the villain was taught by the prince at the beginning."

Chen Dali is a little old man who looks to be in his fifties, although his name is Dali, he can't see his strength at all.

When Li Kuan tinkered with the first glass mirror, he followed him to learn.

"Vigorously, don't be restrained, this king heard that the production level of glass mirrors has been greatly improved during this time, and he is very happy. The firing of glass is the core skill of the Chu Palace, and you can say anything about it. ”

It is not the first time Chen Dali has seen Li Kuan, although he is still a little nervous, but he has a certain understanding of Li Kuan's character, and he is not even difficult to speak.

"Lord Wang, the villain has a reluctant request, can you arrange a few literate guys from Mengxue to come over and help burn the glass? In addition, the villain heard that in Dengzhou, the craftsmen in the workshop can go to the night school, and if we can also do it here, it should be able to speed up the improvement of the glass firing formula. ”

Chen Dali's words made Li Kuan feel a little surprised, he didn't expect such a thin old craftsman to have such a vision.

"Oh, why do you want a literate fellow?"

Li Kuan's mind about teaching was examined.

"Lord Wang, this fired glass, limestone, spar, feldspar and other materials are in different proportions, and the glass produced is also different, even if you accidentally add some wrong materials, it will come out with very different results, which formula is the best, it needs to go through countless tests."

When it comes to what he is good at, Chen Dali has become gushing.

"Relying on brain memory alone, if you remember too much, it is easy to make mistakes, or even not remember at all. This requires literate people to record the recipe, furnace temperature, amount of honeycomb coal added, blast strength and other information for each test, and then continuously improve the ......"

The more Li Kuan listened, the brighter his eyes became, he hadn't found out that this little old man was actually a talent before.

This is already a bit of a later research institute.

"Xuan Ce, you can arrange it immediately. In addition, in all the workshops under the palace, the children of craftsmen can be sent to Mengxue to study, and night schools are arranged, so that those who are literate can have the opportunity to learn. ”

"Lord Wang, please rest assured, my subordinates will arrange it immediately." Wang Xuance nodded; "In addition, the subordinates feel that each workshop can consider recruiting down-of-the-box scholars, these people are knowledgeable and willing to help the workshop......"

"No, you don't." Without waiting for Wang Xuance to finish speaking, Li Kuan denied it, "Those down-and-out scholars, high or low, each heart is higher than the sky, life is thinner than paper, recruiting in will only destroy the atmosphere of the workshop, and the level of the workshop craftsmen still depends on us to find ways to improve." ”

Wang Xuance thought for a while, "What you said makes sense, if those scholars are not high-eyed, they will not be down." ”

"Well, this king has a rule. From now on, all workshops, but all those who have made outstanding contributions to technological progress, the palace will give heavy rewards, specific reward methods, Xuan Ce you set a detailed plan, as soon as possible to the king to see. ”

Chen Dali and the others were overjoyed when they heard this, and hurriedly saluted and thanked them.

"Also, the scale of the production of this glass needs to be expanded, first make a batch of larger glass, it doesn't matter if it's not flat enough, it doesn't matter if there are some impurities, as long as it can transmit light, this king is of great use."

"Lord Wang, if you can transmit light as long as you can do it, and you can ask for everything in color and impurities, the villain can start firing now!"

……

"Your Majesty, there is some new movement on His Royal Highness the King of Chu."

Li Zhong lowered his head and handed a piece of information to Li Shimin.

Seeing that Li Shimin's face was becoming more and more ugly, Li Zhong's head lowered even more, desperately reducing his sense of existence.

"Bang!" Li Shimin slammed the table, "This Li Kuan, he really refuses to stop for a day." Do you think you can squander a sum of gold and silver from the Wa Kingdom? Is this how he sets an example for the people of the world? ”

"Your Majesty, His Royal Highness the King of Chu may be in ...... It's in ......"

Li Zhong originally wanted to find an excuse for Li Kuan, but after a long time, he found that he couldn't think of a reason to excuse himself.

The baby's heart is bitter!
