In order to prevent the idle literati of Jinling City from seizing the opportunity to take advantage of Gu Hengbo and causing the innocent Bo Jue to fall into the center of the whirlpool of public opinion and expose the secret skills of the Industrial Villa, Gu Heng decided to obey Gu Yanwu

If so, start with small things, develop a habit, and pay due attention to your words and deeds even in an industrial villa that seems relatively safe at the moment!

So Gu Heng and Bo Jue kept a suitable distance and came to the glass manufacturing place one after another. They saw large pieces of glass like clear lakes, which looked particularly beautiful under the sunlight!

Gu Heng couldn't help but walked up and touched it. It was very smooth and transparent! Looking at the glass in front of him, Gu Heng had the illusion that he had returned to modern times!

But Gu Heng suddenly woke up. This was still in the late Ming Dynasty! But how can these glasses be transformed into greater economic benefits next?

It needs to be carefully planned. Gu Heng thought about it and figured it out!

Gu Heng hurriedly said: "Brother Bo, Brother Gu, we can make good use of these glasses, and we can make a lot of money. Maybe we can also allow you, Brother Bo, to mass-produce the telescopes you once made!"

"Telescope?" Bo Jue asked puzzledly.

"It's the telescope on the bronze cannon you once helped Governor Zhang Guowei make!" Gu Heng explained.

"It turns out to be this telescope! Is it really possible? But making glass requires a lot of alkali every time, and the amount of alkali in Jinling City is also limited. To be precise, the amount of alkali in the entire Ming Dynasty is limited, because

The oral alkali in the Ming Dynasty was basically provided by the Tatars (Mongolians), and merchants from various places sold it through Zhangjiakou, so the price of the oral alkali in the Ming Dynasty is not cheap."

"If I use these high-priced glasses to make too many of the telescopes you mentioned, and I can't sell them in large quantities right away, I won't have that much money to make glass by then!"

After Bo Jue finished speaking, he looked at Gu Heng worriedly.

But Gu Heng thought of a piece of news he had read in modern times, which said that a large-scale trona mine was discovered in Tongbai County, Henan Province, with proven resources of more than 72 million tons and symbiotic Glauber's salt mineral resources.

100 million tons, of which the scale of trona mine currently ranks first in Asia and second in the world, second only to the Green River trona mine in southwestern Wyoming, USA. The alkali mine is located in the Caozhuang mining area of ​​Tongbai County.

Tongbai, Henan Province is known as the "Trona Capital of China" and is extremely rich in alkali mineral resources. The county's trona reserves account for more than 80% of the national reserves, and the proven trona reserves in the county reach 15%.

billion tons, with prospective reserves of 300 to 500 million tons.

It would be great if I could go to Tongbai County, Henan Province, but the problem is that I can't do it now. Henan is currently Li Zicheng's territory and it's very chaotic, but I must control Tongbai County, Henan Province in the future!

But now that there is not a large amount of alkali, it is still very difficult to produce glass in large quantities. What should we do?

Gu Heng suddenly thought that maybe no one in Tongbai County, Henan Province was paying attention at the moment. How about secretly gathering enough troops to sneak into Tongbai County, Henan Province and control Tongbai County. But if he couldn't do it now, he should first find a way to remove the glass.

Sell ​​it and get enough money!

Gu Heng thought for a while, came up with a few ideas, and then said: "We can use the large piece of glass as window glass first. After all, windows are mostly made of window paper now, which cannot transmit more light like glass and provide a better windshield.

rain!"

"This is a good idea. I believe there will be many wealthy families willing to buy this window glass," Gu Yanwu said.

"So how exactly do you use glass to make windows?" Bo Jue asked a very practical question.

Gu Heng thought back to modern times and felt that aluminum alloy doors and windows with too large pieces of glass seemed unrealistic. After all, aluminum alloys are not available now, so just use wooden windows one by one!

So Gu Heng asked Bo Jue to find pen, ink, paper and inkstone, and draw what a wooden window would look like with pieces of glass embedded in it. Bo Jue quickly figured out how to do it!

After finishing the window, Gu Heng continued: "You can also use large pieces of glass to make a glass greenhouse and grow vegetables inside. This way you can eat fresh vegetables all year round!"

The reason why Gu Heng came up with this idea is because Gu Heng, a person who has adapted to the modern diet, would not be able to eat big fish, meat and pickles every day in the ancient winter!

Hearing this, Gu Yanwu quickly asked: "Is it really possible to grow vegetables in this glass shed without any season restrictions?"

"Yes, but we need to invite farmers who are good at growing a variety of vegetables to plant them." Gu Hengdao.

"Then this glass shed is worth building. Whether it's a restaurant or a big family, everyone will be willing to spend a lot of money to buy these vegetables in winter!" Gu Yanwu said.

"How to make this glass shed specifically?" Bo Jue asked a technical question directly.

Gu Heng quickly drew on the paper and explained to Bo Jue how to do it.

After Bo Jue basically understood the glass shed, Gu Heng added: "The very small pieces of glass we produced before can be used to make glass mirrors. The alloy of tin and mercury is applied to the back of the mirror to make mercury glass mirrors.

, but it’s a bit troublesome, and please note that mercury is poisonous, but it can still be used if the shell is sealed and protected.”

The reason why Gu Heng did not use modern silver plating methods to make mirrors was because he did not have the conditions for the time being, so he could only use the old method of the Western Venetians for the time being!

"What other things can be made?" Bo Jue quickly memorized the several methods Gu Heng just said and asked.

"You can continue to make your telescope, just control the output, not too much, and the technology of glass and telescope must be kept strictly confidential and cannot be leaked to any unrelated person! The craftsmen still use division of labor and cooperation when making it, and no craftsman can be allowed to be independent.

Master all the techniques." Gu Heng told Bo Jue.

"Are you going to sell the telescope?" Bo Jue asked.

"No for now, but you can make two other things after grinding the concave and convex mirror. It should be popular among many scholars." Gu Hengdao.

Considering the important role of telescopes in the military, Gu Heng decided not to sell the telescopes but to block the news and let Bo Jue make other things.

"What is it?" Bo Jue was a little curious.

"You should be familiar with this thing, it's glasses! But you need to improve it and wear different glasses according to the person's age and vision condition." Gu Hengdao.

"I know how to get glasses, but what is vision condition?" Bo Jue started to ask again.

Gu Heng had no choice but to use the knowledge he had learned in modern times to talk to Bo Jue a lot, and even contributed a modern visual acuity chart!

Fortunately, Bo Jue finally figured it out and seemed to know how to do it!

Gu Heng only felt that he was fortunate to have studied science and then worked in a technical field. At that time, he read a lot of historical knowledge and historical fictional novels in order to understand some of the technologies in the historical fictional novels.

, and searched a lot of information!

If this were not the case, Gu Heng felt that he was so unlucky to have traveled through time and became a woman, or a brothel girl, so he could only escape from the world of prostitution by choosing a better man and marrying him!

But now, while I still remember some knowledge about glass, I quickly tell Bo Jue a few things.

Gu Heng then told Bo Jue that cups, teapots, etc. could also be made of glass and the specific manufacturing methods and processes.

Bo Jue learned so much new knowledge and couldn't wait to start testing it. Gu Heng and Gu Yanwu had to leave the industrial villa!
