The New Year of Chongzhen is getting closer and closer. After the New Year of Chongzhen 18, the Ming Dynasty will change the reign of the first year of Shaowu, which means that a new era has begun.

A few years ago, all the new army barracks of Nanjing were completed. The camp was divided into more than 20 camps, each camp had fifty beautiful brick and tile barracks. Each camp lived in five hundred people, and each twelve soldiers lived in a large house. Each officer had his own small single room. There was a public bathhouse, a canteen, and a three-story teaching building in the camp. Each building and barracks had public bathrooms.

More than 20 camps have roads leading to a large comprehensive public area in the middle. There are three-story officer office buildings in the public area, a large venue and lecture hall, a commercial street, and a school.

The school provides families of officers and soldiers with residence. There are family residential areas, casting gun factories, steel factories, glass factories and cement factories around the barracks.

Zhao Peng took Zhu Cilang, Princess Kunxing, Han Zanzhou and others into a factory with no sign at the gate in the barracks.

"Other factories are listed, why isn't this factory listed?" Princess Kunxing asked curiously.

Zhao Peng gently grabbed Princess Kunxing's waist, blew in her ear, and whispered: "Your Highness, what you have made here is our money-making weapon. It is a secret weapon for making money. The country's weapon should not be shown to others."

"What's so mysterious?" Princess Kunxing's eyes showed expectation and curiosity.

Zhu Cixuan snorted: "Isn't it just transparent glass? What's so strange?"

"Your Majesty is such a bad word. You will naturally understand when you see it." Zhao Peng deliberately kept it a secret.

When they walked into the transparent glass factory, they saw that the workers poured the quartz sand on the sieve according to the guidance of Jiangtou Wang Xin, and kept shaking it. Some black impurities leaked from the sieve and fell on the ground. Finally, the sand left on the sieve was relatively large in size. Then they mixed the sand, alkaline earth and filtered limestone fragments together, dried it and sent it into the furnace gallbladder.

The fire burned wildly, and it emitted a blue flame.

Zhu Cixuan found that these fires were not burned with coal or charcoal, but were connected by an iron pipe. The worker just turned on the switch, lit a piece of paper, put it on the furnace mouth, and then got blue flames emerged from the furnace. Then the furnace door of the furnace was closed, and a worker shook the hand-crank blower, and fresh air was constantly sent into the furnace.

"This stove does not require burning coal, firewood and charcoal. What does it burn?" Zhu Cixuan asked curiously.

Zhao Peng replied: "This furnace burns a gas produced when coking in a coking plant. It is called gas by the Europeans in Thailand. We call it gas. This gas is used to burn the furnace, and the temperature can easily reach the temperature of melting steel."

The coke plant is for the service of the steel plant, and the coke produced can be used to make steel. When coking, a burnable gas will be generated in the furnace. These gases are collected by Zhao Peng to be used to provide them to the glass factory for glass refining. Because the stove for burning glass requires a high temperature of more than 1,500 degrees, whether it is charcoal or coke, a special blast furnace must reach such a temperature. Coke is used to make steel, and the "elimination gas" produced by coking happens to be used to make glass.

Because the furnace is heat-insulated from the outside, the temperature inside the furnace is very high, and the temperature of the furnace is so high that it can melt the steel.

The raw materials in the furnace above the furnace gradually turned into red liquid under the action of high temperature, and the liquid flowed into the tank. Under the command of Wang Xin, an apprentice kept stirring the scorching melt.

In fact, Europeans were unable to make flat glass without bubbles for a long time. Only Venetian glass craftsmen could do this. Europeans at that time thought that Venetian craftsmen must have mastered some secrets, so there were no bubbles in the glass they created. Later, commercial spies spent a lot of effort to steal the secret of Venetian glass craftsmen. Finally, the Europeans who got the secret laughed silently. It turned out that the secret was just two words: stirring.

By stirring, the melted glass melt can flow into a large flat mold, thereby making large glass plates. This technology has not been mastered by Europa. In the original historical time and space, it was not until 1688 that Europeans mastered the technology of making large glass.

At this time, it would take more than 40 years for Europe to make large flat glass, and Zhao Peng's glass factory can already be manufactured.

In fact, many technologies are just thin sheets of window paper. No one knows when they are not pierced. Only after they pierce, they realize that these so-called technologies are so simple.

Pour the scorching glass liquid into a heat-resistant container. When the glass melt becomes viscous, a worker puts a tube into the container, picks up a part of the viscous liquid with the iron tube, and then blows it up with his mouth to one end of the iron tube. The glass liquid is blown up like blowing bubble gum.

In order to prevent the blown glass from falling off, you have to turn it while blowing.

After a while, the slightly hardened glass was placed on the platform covered with bluestone. When it was completely cooled, crystal clear glass bottles appeared in front of people.

"Wow!" Princess Kunxing screamed excitedly. You should know that these glass bottles were priceless in the Ming Dynasty in this era. The transparent glass bottles of that year could be sold at high prices like crystal bottles. Any of these glass bottles can be sold for a lot of money. So many glass bottles, wouldn't the Ming Dynasty be about to make a fortune?

At this time, on the other side, the glass plates were made. Looking at the large glass plates that were two feet long and one foot wide, Zhu Cixuan's eyes were straightened: "How much silver does such a large transparent glass plate cost? I only know that when I was a child, a transparent glass plate less than a foot square in the palace was said to be priceless."

"There is no value after too much stuff. Now, while others don't know, we can make a lot of money! These transparent glasses can be sold to Jiannu, to Japan, to North Korea, and to Nanyang to Thais." Zhao Peng said with a smile.

Some of the glass plates were sent to a workshop next door by the workers, and Zhao Peng also took Zhu Cixuan and Princess Kunxing into the workshop.

The workers in the workshop carefully scrubbed the glass plate and placed it next to the wall. On the other side, someone poured the ground silver powder into the liquid, stirred it evenly, and then evenly applied it to one side of the glass plate. After applying it, a layer of liquid was applied on it. Not long after, the glass plate turned silver white and shining.

The worker painted a layer of copper-yellow paint on the silver-plated side. In fact, it was not paint, but covered the silver-plated glass plate with copper to ensure that the silver powder inside would not fall off.

Zhao Peng picked up a mirror about two feet long and one foot wide that was completed two days ago. This mirror has been installed with a wooden frame. With the raised wooden frames around it, the glass mirror will not be easily broken.

When the mirror stood in front of Princess Kunxing, she looked at a palace beauty in the mirror in a daze, her mouth was wide open. After a long time, she asked blankly: "Is this a mirror? Is it myself in the mirror? It's really clear!"

This is of course the first time Princess Kunxing has taken such a large glass mirror. The first time she saw her whole picture clearly, which shocked herself. She was so beautiful and dignified in the mirror, and her whole body exuded a noble temperament.

I used to use bronze mirrors, but the clarity was far less than that of glass mirrors. The first time I saw myself so clear, Princess Kunxing was naturally extremely excited.
Chapter completed!
