The alum and graphite were found by Chen Wanrong and Li Longji. With these two things, glass can be made. If Chen Wanrong had not participated in the battle in Tubo, he would have handled this matter long ago. Of course, the treatment was only for making money, to quantify chemical industry, and now it was to promote the arrival of the era of science and technology.

Whether it is chemical industry, medicine, or fertilizer, it needs to be analyzed, tested, and used glass. Once the glass is made and the corresponding reagents are made, these related industries will develop in terms of quantification, which has a far-reaching impact.

The word "baby" can no longer explain its importance!

Chen Wanrong's eyes shone. After careful examination, he found that the gallbladder and graphite in the room had piled up most of the houses, each of which was at least several thousand kilograms, not far from ten thousand kilograms.

Li Longji spared no effort. As soon as Chen Wanrong came back, he had alum and sulfuric acid, and he did it again.

"My friend, is it really useful?" Ye Tianheng was a little disbelief.

Chen Wanrong was very sure: "It's not useful, it's very useful. This is a gallbladder, which can make sulfuric acid. If you want to make sulfuric acid, there are many ways, but we can only extract it from the gallbladder. When the conditions are ripe in the future, we will use other methods to make sulfuric acid."

"General Chen, what's the use of this dark thing?" Kou Yibing asked in confusion.

Chen Wanrong picked up a piece of graphite, looked it for a while, and said with a smile: "This thing is also a treasure. With sulfuric acid, you can process graphite. Once the graphite is processed, we can make a glass-making crucible and refractory brick."

Although Kou Yibing and the others didn't understand what the crucible was, they were the masters and vaguely guessed it and asked, "Why do you have to use graphite?"

Chen Wanrong explained: "One of the benefits of graphite is that it is heat resistant. Glass is very hot, which may be hotter than steelmaking. If there is no graphite, the crucible will deform as soon as it is burned. It can only be used once, and it will not be used again next time."

The temperature of steelmaking is also very high, but our ancestors were very clever to use limestone to reduce its temperature, which reduced the difficulty of steelmaking. The temperature of making glass must reach 1,670,000 degrees, which is only higher than that of steelmaking.

The temperature for steelmaking is already very high, and the temperature for making glass is even higher. Ye Tianheng and others straightened their mouths, and this heat-resistant equipment alone surprised them.

Ye Tianheng, who understood, smiled and said, "My friend, are you asking for these things just to make fire-resistant equipment?"

Chen Wanrong nodded and said, "Yes!"

Ye Tianheng patted his forehead and said embarrassedly: "I'm so embarrassing. This graphite is so heat-resistant, I actually burn it with fire. No wonder there is no change."

Graphite can withstand high temperatures of 3,000 degrees. Normally, flames only have a few hundred degrees of temperatures, so how can I do it? Kou Yibing and others were also involved in this matter, and they couldn't help but feel embarrassed and laughed awkwardly.

Chen Wanrong explained to them how to extract sulfuric acid, how to process graphite, and how to make crucibles. These things are far from what Ye Tianheng and others can imagine. They listened very carefully and were surprised. Until Chen Wanrong finished speaking, they were all surprised.

Ye Tianheng immediately came up with an idea: "My friend, we can do this crucible, we can process the graphite first."

"Yes!" Everyone felt itchy when they heard Chen Wanrong talk about the use of glass in detail. They really wanted to make it earlier, and they were all overjoyed.

As long as they know the method, Chen Wanrong doesn't need to interfere in other matters, they naturally know what to do. Liu Huaide arranged for people to start refining sulfuric acid.

After arranging the sulfuric acid work, Ye Tianheng pulled Chen Wanrong and said, "My friend, this glass should be very troublesome, right? We have to make a good summary, choose where to do it and what to do. Once the summary is complete, we can do it first so as not to get messed up."

"Yes! General Chen, what are your requirements?" Kou Yibing agreed with this.

Chen Wanrong pondered: "Glass is very useful, but with our current ability, we can only use it as a tool. The heating furnace is not difficult, just build one. The crucible can also solve it. These are not problems. The main problem is blowing. I want to make tools. Various models are indispensable. Also, where does this energy come from?"

What Chen Wanrong wanted to do was to analyze the utensils instead of construction glass. It can be imagined that if the construction glass is really made, it will be very popular and can be sold at a high price, which is not inferior to perfume and soap. However, there are more important aspects that require glass.

Initially, when it comes to blowing glass, the Phoenicians used people to blow, which was time-consuming and labor-intensive. Not only was it inefficient, it also had a great harm to people's bodies. Chen Wanrong would definitely not do this. Using a bellows is a good choice, but there should be a better way to use the military weapon supervisor.

Ye Tianheng smiled and said, "Blow the air? What's the difficulty? Put it on the edge of the Wei River and make a few water drains, and there is no problem with blowing strong winds."

This is a good idea, Chen Wanrong highly agrees: "However, this needs to be improved."

Kou Yibing nodded and said, "That's natural. There are different ways to use this water drainage when it is used in different places. General Chen, what are you going to do?"

Chen Wanrong found a piece of charcoal and drew a cup on a wooden board. This cup was completely different from what Ye Tianheng and the others had seen. He couldn't help but ask curiously: "My friend, what are you?"

"This is called a beaker!" Chen Wanrong explained to them: "The most commonly used instrument for chemical testing."

"This is also called a cup? It's round, but it's not as small as a wine glass, but large on top." Kou Yibing commented.

His association ability is really good. Chen Wanrong laughed and drew something casually and said, "This is a cone flask, used for analysis. This is a burette, this is a straw."

They explained the use of it one by one, but fortunately, Ye Tianheng and others were not confused when they heard it.

"These things all require a scale and need to be accurately counted. Master Kou, are there any problems?" What the analysis requires is accuracy, and what the measurement is accurate. Who else can I find if Kou Yibing is not looking for this matter?

Maybe you don’t need milliliters, you don’t need to increase these units of measurement now. No matter which unit you use, it’s as long as it’s practical.

Liu Huaide smiled and said, "General, don't you worry about this. Didn't Master Kou do the detector you drew well? What's the difficulty?"

Which is more difficult, chemical instrument measurement or vernier caliper? No need to think about it. Even vernier caliper can be done, so there is no problem with this. Chen Wanrong said happily: "Then I will have Master Kou!"

"If you have a heavy word, if you have a heavy word, you should do it!" Kou Yibing smiled.

Chen Wanrong slapped his right hand on the table, and his voice increased a lot: "Master Kou, there is a thing called a thermometer that can be used to measure heat. For example, the weather is relatively cold today. How cold is it? You will know it by measuring it with a thermometer. This thing is very useful. Can you do it?"

Temperature is an extremely important parameter in chemical industry. Inorganic chemistry does not have too high requirements for temperature, and organic chemistry controls temperature very strictly. Some reactions are completely different if they are only a few degrees apart. Especially for explosives factories, a few degrees apart in temperature may cause a big explosion.

If the temperature cannot be solved, chemical industry will still be difficult to achieve great things. Now that glass is in sight, can Chen Wanrong let it go?

"Temperature?" Ye Tianheng and the others asked in unison.

Chen Wanrong knew that they were a little confused: "The temperature is about measuring how hot it is. Steelmaking is very hot, but we don't know how hot it is. We only know that it is very hot, and we have to control it by experience. If we make a thermometer and put it there, we can tell whether it meets the requirements at a glance."

They could only explain it in a way they could understand. Unexpectedly, the three of them shouted in unison: "Good idea!"

Ye Tianheng sighed: "When it comes to steelmaking, this popularity is very critical, but not many people can master the popularity well. Without years of accumulation, it is impossible to hold on to the good heat."

This was very helpless, but it revealed a message, that is, why there were so few masters. In ancient times, there were few detection methods, and many things could only be based on experience. Experience was difficult to play a role without years of practice and accumulation. In modern society, there were many detection methods, and whether it was good or not, you would know once you check. If you don’t need a master, we can also make good things.

In ancient times, without a master's inspection, some things were difficult to make, and it could be said that they were impossible to make.

After hearing this, Chen Wanrong's eyes shone brightly and he couldn't help but complain: "Why didn't I think of this? Master Ye, you have a lot of experience. When our technical means are improved, you will tell us your experience, we will sort it out and detect it for your reference. What will you think?"

"What else can I do? Of course, I am the master, I am idle at home!" Ye Tianheng twitched his chest, but his face was smiling and his eyes were particularly bright.

As a master, he knew very well how rare a master was. With so many disciples, how many people could get his fortune? How many people could reach his level?

If these experiences are turned into data, people who don’t need to be very talented can understand and do it well, and he, as a master, can only be unemployed. This is a great thing, who can be unhappy?

In ancient times, the inheritance of skills was very secret. Those masters always cherished their own secret skills and would not easily be known. And why can we have an industry that has flourished in modern times? In addition to the development of technology, the threshold for technology has been lowered. Which factory does not have "crafts"?

With process standards, it will be easier to do, and it is impossible to do if the industry is underdeveloped.

If this is true, the Tang Dynasty's technological level will take another big step forward!

Liu Huaide, Kou Yibing and others patted Chen Wanrong's shoulders together: "General Chen, you are more thoughtful. You should do this! A master has a great influence. It's not that he doesn't want to find a successor, but the successor he found cannot inherit his legacy. Often, his skills are lost. With your method, his skills will not be lost. Everyone is a master. How good should it be?"

The more he spoke, the more excited he became. Chen Wanrong couldn't help but pat his chest: "No matter what, this must be done well. First of all, he has to get the detection methods out."

"Don't worry, I'll make a thermometer no matter what." Kou Yibing also patted his chest.

Not to mention, the grade of iron ore is different. The iron ore produced in different places has different iron content and technical treatments. If there is no testing method, just relying on experience to change the ore and how to deal with it, it will take a while. If there is testing method, you only need to sample and check it to know the iron content and how to deal with it. This benefit is very obvious and easy to understand.

Kou Yibing believed that this matter was unrestrained and must be done well!

The thermometer has a lot to do. Chen Wanrong will explain to Kou Yibing how to make it and how to measure and measure the thermometer. Chen Wanrong has never done it before, and he also has some understanding. After explanation, Kou Yibing's eyes shine and his confidence is even more complete. "It must be done well!"

The temperatures required for chemical reactions in Chen Wanrong's memory are all modern. If the thermometer made is not a modern unit, then the reaction temperatures that Chen Wanrong remembers will be useless and have to be done over again. Then this skill will be great, so this thermometer must be a modern unit of temperature.

Looking at Kou Yibing's eagerness to try, Chen Wanrong was also confident that he could make a thermometer that meets the requirements!

It took Chen Wanrong's time to finish the explanation. Next, he discussed some details and the matter was over. Thinking about the inspection, Chen Wanrong was really excited. Li Longji really rained in time and gave Chen Wanrong the best gift!

He picked up the teacup and took a few sips. His dry throat was better. Chen Wanrong asked with a smile: "What's wrong with the students?"

"Is that a student?" Ye Tianheng put the teacup in his hand and blurted out.

Chen Wanrong was shocked and asked hurriedly: "Master Ye, do they want to be in the military weapon supervision?"

Kou Yibing patted Chen Wanrong's shoulder and said, "General Chen, you know. Master Ye likes to keep inseparable. He teases you. At the beginning, these students came for the third-level title, but the people came, but their hearts did not come. However, after Brother Ye taught them, they all felt at ease and had to continue working in the military weapon supervision no matter what."

If there is no third-level title, will these students come to the military weapon supervisor? They won’t even be carried by sedan chairs. It is normal for them to be unstable when they come. Ye Tianheng is the banner of the military weapon supervisor and a famous craftsman. What a blessing to be able to listen to his lectures?

Ye Tianheng also understood that they had to keep their hearts. In this way, there was also the principle of not using all their skills. Only witnesses could imagine the level of excitement. How could the students feel uneasy?

"Master Ye, it's hard for you." Chen Wanrong said with regret: "I have something to do these days, so I've put it aside. I haven't listened to Master Ye's lectures. It's a pity!"

Liu Huaide also became interested: "We all know that Brother Ye has a profound attainment, but he didn't expect to be so insightful when he taught. General Chen, I counted in secret, and there were thirty-one people who were ticking and ticking. More people heard this, opened their mouths wide and didn't even turn their eyes."

Imitating the focused appearance of the students was really vivid, and Chen Wanrong couldn't help laughing.

The students were used to listening to the Four Books and Five Classics, but they knew nothing about these skills. They sounded fresh in simple things. Under the explanation of the master Ye Tianheng, these things were magical and they couldn't do it if they were not interested.

"I have never heard of such a wonderful theory in the years since Brother Ye and I have been together! Brother Ye, you are this!" Liu Huaide finally gave Ye Tianheng a thumbs up.

It is normal for Chen Wanrong to meet a good tutor in this lecture. He was stunned and stupid when he heard this. When Chen Wanrong was in college, he encountered this kind of experience many times. When he recalled the scene at that time, he couldn't help but feel very friendly.

"There are so many questions about Gao Jian. Fortunately, we are. If we change someone, we will definitely ask him if he is poor." Ye Tianheng said very applauded: "My friend, among these people, Gao Jian will definitely become a good craftsman and need to be well trained."

Gao Jian likes to study, Chen Wanrong has some insights and smiles: "That's. Master Ye, don't you think about accepting him as a disciple, right?"

"What's wrong?" Ye Tianheng's crutch in his hand kept twitching on the ground.

Chen Wanrong slapped Ye Tianheng's back of his hand: "Master Ye, we have agreed that you can't hide your own personal information. You have to tell them all, and you have to give them all."

Kou Yibing attacked Ye Tianheng and said, "Brother Ye, don't be wishful thinking. Do you know who Gao Jian has the best relationship with? Who do you want to be the teacher the most? He is determined to be the Taoist priest."

After getting Chen Wanrong's whereabouts, Sima Chengzhen did not follow him to rescue him. Is there still so many people who can't be rescued? He came to the military weapon supervisor to teach the course.

Chen Wanrongda was interested and asked, "What did Taoist priest say?"

"What else can it be? Of course, what is the reaction? What is the speed of burning with more oxygen? It sounds like elixir is not like elixir, but it is much more clever than elixir." Liu Huaide touched his forehead, thought while explaining.

"That's chemistry!" Chen Wanrong answered in his heart.

Since Sima Chengzhen came to Chen Wanrong, he has learned a lot of chemistry knowledge. He is a famous alchemist and his understanding of chemistry is much easier than that of ordinary people. Chen Wanrong will understand it with one plus point.

It can be said that in the Tang Dynasty, except for Chen Wanrong, Sima Chengzhen knew the most about chemistry.

Chemistry was already very magical for the Tang people. I would like to explain to Sima Chengzhen while doing some small experiments, so the students would not hit their eyes on the ground?

Gao Jian is most enthusiastic about these things. What's so strange about being attached to Sima Chengzhen?

"I explained it to them and asked them to follow and see it. They were all so excited that they were like crowing roosters." Ye Tianheng admired the enthusiasm of the students very much.

"Let's go, I'll go see them too!" Chen Wanrong stood up and said, "This time I went back to Ning County, and I went to the county hall to recruit twenty students and arrived in two days."

Ye Tianheng punched Chen Wanrong on the shoulder: "My friend, you really have to get a bargain wherever you go!"

When I came to the workplace, I saw that there were more people working today, which was much more lively than before. The students followed the masters of the military weapon supervisors to work hard, all of them were excited and everyone worked hard.

It seems that they are really at ease doing it here.

"Brother-in-law, you're back!" A familiar voice sounded, and then a big flower face appeared in front of you. It was no one else, but Zheng Wanru, with a black flower on her white face, you can sing Beijing without makeup.

Look at his body, a piece of dust, a piece of mud, and a piece of dirty body, which is completely different from the usual clean Zheng Wanru.

"It's like, look at you, you're the dirtiest!" Chen Wanrong looked around.
Chapter completed!
