"Your Highness, it seems that this agriculture is still the foundation of the country, cotton, rape, hemp, etc., which are all planted by the people of the fiefdom in the next step. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

Xiao Ming had a headache for cotton, Pang Yukun took the opportunity to say, he felt that Xiao Ming paid too much attention to handicrafts during this time, but ignored the fundamentals of agriculture.

"You're right, but now there is still a shortage of food, and it may be difficult for the people to plant these things, after all, they have to bear the risk of not being able to sell them at that time, so let's let the production corps carry out some planting first, and then continue to promote it when the production of grain stabilizes."

Xiao Ming said.

Pang Yukun nodded, during this time, he and Xiao Ming had been planning the agriculture and industry of the six states, and these were all in the plan.

"Also, Your Highness, what is this new commodity?"

At the last banquet, Xiao Ming threw out another bait, but because of the problem of fine work, everyone ignored it, and now Pang Yukun mentioned it again.

"Mirror." Thinking of this new commodity, Xiao Ming laughed.

At present, the Great Chongqing Kingdom still uses a bronze mirror, which is very blurry and cannot see the specific details of the face.

Modern mirrors, on the other hand, are glass mirrors, which allow the mirror to reflect people clearly by plating aluminum on the back of the mirror.

However, it is impossible for Xiao Ming to extract aluminum now, because the extraction of aluminum requires electroanalysis, and the traditional silver mirror reaction requires nitric acid, ammonia, glucose and other things, and he also has no way to produce mirrors by chemical silver plating.

After all, there are some industrial products that cannot be produced without electricity.

After thinking about it, he thought that with the current conditions, only glass, tin foil, and mercury could be used to get a mirror.

"Mirrors? Bronze mirrors? There are so many of these Great Chongqing countries, the lower officials think there is nothing new about it. Pang Yukun said.

Xiao Ming shook his head and said, "What this king wants to produce this time is a glass mirror, and this king will show it to you in two days." ”

Li Kaiyuan's face was excited, after waiting for so long, he finally had to have new goods, and he could already imagine that the merchants would fill the Chamber of Commerce with a flood of paintings by then.

Thinking of this, he couldn't help but smirk.

Xiao Ming saw him with an obscene look on his face, and reminded: "The task now is to purchase cotton, if you delay the voyage of this king's fleet, see how I clean you up!" ”

Li Kaiyuan snorted, "Yes, Your Highness, I'll do it now, but Your Highness, this mirror should be hurried." After that, he laughed lewdly again.

"This king is about to go to Bowen College to find Lu Tong to talk about this silver mirror." As he spoke, Xiao Ming stood up.

After that, Xiao Ming and Li Kaiyuan left the Governor's Mansion together, one of them went to the Chamber of Commerce, and the other went to Bowen College.

A few days ago, when Pang Yukun mentioned the new product, Xiao Ming told Lu Tong about the preparation of the mirror, and asked him to prepare tin, mercury and other materials.

Although Xiao Ming did not find any mineral deposits in the local area, tin is a very common metal in Dayu, and the alloy of copper and tin is bronze, which appeared in ancient times.

As for mercury, it is the same, in ancient times, mercury was still a medicinal material, and it was not difficult to get mercury, and the preparation of mercury was also very simple, that is, heating cinnabar to obtain mercury and sulfur.

And cinnabar is a thing that can often be seen in the Dan prescriptions of Taoist alchemy, which shows the degree of commonness.

When he arrived at Bowen College, Xiao Ming went directly to the chemistry laboratory, and Lu Tong was waiting for Xiao Ming at this time.

"Your Highness."

Seeing Xiao Ming coming, Lu Tong led a group of students to bow to Xiao Ming.

Xiao Ming nodded and asked, "How is it?" Are the materials ready? ”

"It's all right." Lu Tong said.

Then he took Xiao Ming to see the mercury and tin in the glass container, and there was a pile of glass on the table in front of him.

Since the preparation of sulfuric acid, the students of the entire School of Chemistry have been producing granular gunpowder, and now they have prepared three acids and two alkalis, sulfuric acid, caustic soda, and soda ash, but nitric acid and hydrochloric acid have not been tried.

However, Xiao Ming already gave them chemistry textbooks on how to prepare nitric acid and hydrochloric acid, and during this time, Lu Tong was preparing to take the students of the School of Chemistry to try.

Among them, nitric acid is prepared to be obtained by decomposing saltpeter at high temperature and high heat to obtain nitrogen dioxide and integrating it into water, and hydrochloric acid, which they are preparing to use concentrated sulfuric acid and table salt.

However, looking at Xiao Ming's appearance, it seems that he just wants to hand over the knowledge of chemistry to them, and let them study the rest by themselves.

After checking the materials, Xiao Ming said, "Let's start, I say, you do it." ”

Lu Tong nodded, now Xiao Ming faintly has a sense of letting go of the shopkeeper, and let them try everything by themselves.

In fact, Xiao Ming also knows what Lu Tong and others are thinking now, but there is no way, knowledge is not stored in the head, but used for practice, during this time, Xiao Ming has already handed over the symbols of chemical elements to Lu Tong.

They also know the chemical periodic table well, and his textbook can be said to be much more carefully compiled than the junior high school chemistry textbook, with all the simple chemical reaction formulas on it.

The rest of him can only rely on Lu Tong and others to realize the chemical experiments in chemistry textbooks, so as to apply them to the chemical industry, otherwise what is the use of learning knowledge? Moreover, with the current level of science and technology in Chongqing, junior high school chemistry knowledge is more than enough, and advanced chemistry will involve electrolysis and the like.

If there is no electricity, it will be blind if you learn.

Taking a piece of glass, Lu Tong pasted a piece of tin foil on the back of the glass, because the melting point of tin is very low, only more than 200 degrees, so smelting tin foil is very simple, as long as it is slightly heated.

After wrapping the tin foil, Lu Tong took out the mercury and poured the mercury on the tin foil and spread it evenly.

At this time, mercury and tin foil had a chemical reaction, turning into a silvery-white liquid, this is tin amalgamation, historical records, this mercury and tin produced by the solution existed in the Spring and Autumn Period and the Warring States Period, and although mercury is toxic, but amalgam alloys are non-toxic.

This silvery-white liquid adheres tightly to one side of the glass and does not come off easily.

The steps of producing mirrors were completed one by one, and Xiao Ming and Lu Tong quietly waited for the moment when a miracle appeared.

Half an hour later, when the metal solution was completely dry, Xiao Ming picked up the mirror, and then he saw himself clearly in the mirror.

A young, a little handsome face, "Hey, it's been a year, and it's the first time I've seen my face clearly." ”

Xiao Ming sighed.

At this time, the mirror in his hand was not much different from the modern mirror, but it was a little dimer, after all, tin amalgam was still not as bright as silver.

But even so, this mirror is probably a masterpiece of the world.
