Chemistry is one of Li Guo's majors, and chemical engineering is something closely related to life.

Therefore, disseminating chemical knowledge is also one of Li Guo's most urgent things. The main law of chemistry is the law of conservation of mass, which is essentially the law of conservation of energy.

Li Guo took a piece of paper, lit it, and the paper turned to ash.

"Where's the paper?" Li asked.

"It's gone." Everyone replied.

Li Guo patiently explained, yes, although the paper is gone, the quality is still there, and the paper has been transformed into other things, turning into ash and smoke.

The reason why this is the case is because everything is made up of atoms. When the mass of an atom changes through the action of energy, it becomes something else.

It's like glass, if you smelt sand, limestone, and soda ash with a certain ratio and smelt it with fire, it will become glass. This reaction is a chemical reaction.

Li Guo taught physics and chemistry with good intentions, but in fact, his idea originated from the manufacture of glass.

Li Guo was determined to start with glass and truly overcome a difficulty in science and technology at the end of the Ming Dynasty. Because the technical content of glass is not high.

Therefore, Li Guo decided to set up a scientific research institution in physics and chemistry because of Song Yingxing's initiative and hard work, coupled with Li Guo's trust in him. After the establishment of this scientific research institution of the Beihai Research Institute, Song Yingxing was still in charge. The members inside are also people who have listened to Li Guo's speech these days and are extremely interested in Li Guo's views. They come from different fields. I will study different topics.

For these people, Li Guo gave them extremely high treatment, food, clothing, and use. is much stronger than Li Guo, but everyone here, Li Guo is strictly protected. Because Li Guo will focus on cultivating them, the knowledge they have cannot be leaked.

And now, Li Guo has only one request, that is, they will do a good job of glass.

Li Guo is in great need of glass at the moment, because Li Guo is desperately in need of money now.

Li Guo encountered a great dilemma at this moment. Money!

What to do? Earn! What is the fastest way to make money and make the most profits? Glass!

Say something troublesome. Li Guo has never been rich since he traveled to this dynasty in the original time and space, and he has always been short of money!

When I was in Shaanxi, there was just an improvement. As a result, he fought a battle with the Jurchens of Houjin outside the gate and became poor. Because of the heavy casualties, the pension alone made Li Guo a poor egg!

It was easy to get to Guangxi, and it was another battle with the Mo Dynasty, the Houli Dynasty, and the Ruan Dynasty! It should have been rich, right? Poorer. The Mo Dynasty was okay, Li Guo didn't move him, and there were 300,000 taels of silver a year, but the Mo Dynasty was a flood this year, and he only barely paid a tribute of 100,000 taels of silver.

Moreover, Li Guo still has to think of ways to build weapons. It would have required a lot of money. After a few battles, many of the firearms in Li Guo's team were no longer usable, because the steel material was not good. A lot of barrels exploded!

In order to better consolidate the territory of Annan, the large-scale resettlement plan promoted by Li Guo cost a lot of money, and in the southern part of Annan, Tie Dan led people to quell small-scale rebellions and implement land reform plans. Let's say reassure the people, put in the seeds. Helping with planting and so on.

Li Guo's current territory is large enough, and the entire Annan region is controlled by Li Guo except for Guangxi. The sea has extended its influence to Malacca, although it is possible to escort merchant ships from Macau to Malacca for a fee, and ships passing through Malacca are also taxed, but this method of making money is long-term, but it will not solve the big problem in the short term.

And making good glass is the key, because the whole Ming Dynasty does not have it, and this thing will definitely be able to make money.

In fact, the glass has been made, but the quality of the glass produced is different, and it is very unstable.

After Li Guo carefully analyzed the reason, he found that this is because the composition of sand, the main raw material for glass, is different. This requires a chemical understanding to further analyze the composition of the raw materials. In addition, the output of pure manual production is too small, and the real production scale and industrialization have not yet been formed, and some technical problems are very thorny and not so easy to solve.

As a result, the personnel of the Beihai Research Institute took samples from each other. The sand in each region is tested one by one. In this way, the most suitable sand was finally found in the area of Pak Sha Kok, east of the North Harbour. Li Guo deliberately went to Baishajiao to take a look, heh! Endless white sand beach with more sand.

Li Guo nodded, the sand was enough. But Li Guo also instructed the researchers, "We still have to thoroughly understand why the sand here is made of good glass, and how the composition of the façade is different from the sand in other places!" We must pay attention to the spirit of digging into the bottom of things, so that we can do a good job in learning! ”

The accompanying researchers are all knowledgeable people, and during this time, Li Guo lectured on physics and chemistry, and these people have long admired Li Guo's knowledge. Hearing Li Guo's command, no matter whether it was Eastern or Western, everyone nodded in agreement.

After the quality of glass is guaranteed, it is necessary to pursue quantity. No matter how good your quality is, it is useless to not be able to produce a piece of glass in a month. Only when there is output can there be great benefits. Li Guo is not afraid of a large amount, because there is no such thing as glass in the entire Ming Dynasty, so Li Guo can only do it, and the monopoly must be profitable.

And it was Song Yingxing who realized the mass production of glass.

Li Guo couldn't do everything himself, otherwise he would have died of exhaustion. Li Guo just appropriately mentioned some Jianyì.

Song Yingxing made full use of the principle of the steam engine, using the heat of smelting glass as power, through a series of mechanical devices, in a certain specification of glass solution pool, with the same specification of the pull rod to pull out the glass, and then along the conveyor belt to stretch outward, before the solution has cooled and solidified, a reasonable cutter will cut the glass into the same size. As a result, the output of glass has increased significantly.

Li Guo looked at Song Yingxing's machinery and stretched out his hand, "Yingxing, well done, ah this conveyor belt is made of leather, well, yes, the power of steam can drive the round roll under the leather, so that the glass can be continuously pulled out at a constant speed." Very well, there will be more inventions of such machines in the future. ”

Song Yingxing heard Li Guo praise himself, and he couldn't close his mouth with a big mouth. "Master Tiger, these things called glass are good, but what's the use?"

"You idiot, glass can make windows! Now the entire Daming windows are papier-mâché, if we all buy our glass to make windows, how much money do we have to make? ”

Li Guo laughed, this time he can make a fortune, make a fortune.

However, Li Guo was not in a hurry to sell door-to-door. If you want to make a lot of money, you have to let people beg you, so what?

The era of Li Guo's crazy money-making began to come. (To be continued)
