Although Zheng Qing was curious, meeting Chen Wanrong's request was what she was most willing to do. When she heard Chen Wanrong's speech, she was excited and hurriedly said, "Brother Chen, come with me." She slapped her horse and ran faster.

Chen Wanrong followed up with the horse and asked repeatedly: "Qing, where is it?"

"Let's go north, but it's a little far." Zheng Qing pointed to the north with a whip and estimated it a little, "It's about half an hour to run."

With glass, Chen Wanrong's chemical engineering will go to a higher level. Not to mention the journey that lasted half an hour, he didn't care no matter how far he was, and smiled and said, "It's okay, I'll go here and hurry up."

In a hurry to see Fengstone, Chen Wanrong didn't say much, just rushing to the horse. Although Zheng Qing was curious and wanted to ask clearly, Chen Wanrong was so anxious that she was so understanding that she would not break the casserole and ask to the end, so she resisted and didn't ask.

After a hurry, I arrived in front of a mountain for about half an hour. This mountain is different from the western mountain. The western mountain is desolate, but there are many farmers nearby, and many farmers are busy in the fields, making a pastoral scene.

Zheng Qing pulled the reins and turned on the path eastward, followed the path to the foot of the mountain. Zheng Qing pointed to the stone on the ground and said, "Brother Chen, look, it's this stone."

Chen Wanrong saw that this was a flesh-colored feldspar lying in the grass. Feldspar for the Tang people had the effect of curing diseases, and there was no use other than that. Therefore, even if the Tang people saw it, they would not pick it up, and it was normal to see it on the roadside.

After jumping off the horse, Chen Wanrong picked up the feldspar and threw it in his hand. He was very happy and pointed at the feldspar and said to Zheng Qing: "Qing, do you know? With feldspar, I am like a tiger with wings. This chemical industry is more vivid."

Zheng Qing jumped off the horse, looked at Chen Wanrong, and asked, "Brother Chen, is it true?"

"Of course it's true! No one will lie to you!" Chen Wanrong was very confident.

After hearing this, Zheng Qing was both happy and shy, and said half-angrily and half-happy: "Brother Chen, don't say such things, okay?"

Today, Chen Wanrong was able to discover feldspar and her achievements. She did not embarrass her too much. She nodded and said, "Okay. Soda ash is ready-made; quartz sand can be found by the river, which is not difficult; wherever the stone is burned, there will be limestone, and these are not a problem. With feldspar, I can make glass."

Zheng Qing asked in confusion: "Brother Chen, what is glass?"

Although this was a simple question, it stumped Chen Wanrong. After thinking about it, he said: "Bolli can transmit light. If there is a piece of glass in the middle of us, I can not only see you, but also see it very clearly."

"Brother Chen, it's better not to do it." Zheng Qing couldn't accept it when there was a layer of things between the two.

Chen Wanrong understood what she meant and quickly explained: "Qing, don't be too careful. I'm just making an example. Glass can also be made into a utensil and put on things, so you can see it clearly."

"Is that?" Zheng Qing asked, pondered for a moment, and then asked, "Brother Chen, is it the same as Liuli?"

Glass and glass have the same chemical composition, dioxygen and silicon, but the difference between the two is very big. Glass is the first of the five famous Chinese instruments, as famous as gold, silver, jade, ceramics, and bronze. It is one of the seven treasures of Buddhism and a very precious work of art. It is often used as architecture and decoration and is loved by the ancients.

The production process of glass is long, with nearly fifty processes ranging from conception, design, firing and polishing, which is extremely complex. More importantly, it is necessary to make handmade. Even if the craftsmen master extremely advanced skills, they cannot guarantee that the color of the product is consistent, and there will inevitably be differences. Therefore, the color of glass is different and different.

The most difficult thing is that one mold can only burn one work, and a mold can not be reused. If you encounter a large work, it needs to be repeatedly burned, which is extremely complicated. This leads to the very low success rate of glass, and the corresponding glass is also very precious. Having glass is a symbol of identity and is cherished by the ancients.

Glass can be produced in an industrial manner, and its collection value cannot be compared with glazed glass. In terms of use, glass is better. It is home decoration. It is used on doors and windows to improve the living environment and provide convenience for our lives. If modern high-rise buildings do not have glass, it is not impossible, but very few.

Not to mention, glass is the main product of chemical laboratories. Without glass products, it is unimaginable to establish a chemical laboratory.

The difference between this is obvious. It is not a problem to Chen Wanrong, but Zheng Qing may not understand it. Chen Wanrong was stunned for a moment and then said: "Different. Although glass is exquisite, it has poor light transmission. Things are not very good to put in it. However, glass is different. It is transparent and can be seen like people who are not wearing clothes."

This is a very vivid metaphor, and Zheng Qing naturally understood it as soon as she heard it. However, this metaphor was a bit embarrassing for her woman, and she blushed and said, "Brother Chen, don't you say this?"

Chen Wanrong regretted it very much. He shouldn't use this metaphor. He patted his mouth lightly and nodded, "Look at this mouth, just say something useless."

Zheng Qing knew that Chen Wanrong was taking a light shot, but still felt distressed, and said angrily: "Brother Chen, don't hit yourself, okay? Brother Chen, the glass you are talking about is one of the glass. The glass of the Great Yuezhi, the stone in the mountains and the five-color glass is cast, which is more exquisite than the glass of Middle Earth. The glass can be produced in large quantities, so the glass of Middle Earth is reduced and in the end it becomes less and less, and it is gone. The ones that are stored are just glass used for building houses."

The failure to use transparent glass instruments made alchemists miss many valuable chemical phenomena, which eventually led to the far-leading Chinese alchemy not developing into chemistry. This is a great regret for ancient Chinese technology.

Chen Wanrong was deeply regretful about this. In his impression, there should be no Belle in ancient China. After hearing Zheng Qing's words, he was very surprised and asked, "Qing, is there really such glass?" Now this glass is another way to say that glass is glass.

In ancient China, there was not only glass, but also lead-barium glass. It was once popular in the world, but later it was introduced from the West, leading to the extinction of ancient Chinese glass. Chen Wanrong's historical knowledge was not good and he did not understand this history.

For Zheng Qing, Chen Wanrong's question has always been answered, nodding and said, "Yes! This kind of glass first appeared during the Spring and Autumn Period and the Warring States Period. At that time, when the kilns burned porcelain, they found that there were blue-green stones in the slag. When the stone shone against the sun, it looked very beautiful and beautiful. After it was fired, it was sold on the market and it was once popular."

The ceramic slag contains copper and iron ions, which show different colors. This was an unexpected gain of the ancients, and the development of China's glass industry emerged. However, during the Northern and Southern Dynasties, a large amount of Western glass flowed in, which really made people sigh.

There is actually such a tortuous history, Chen Wanrong sighed: "I really didn't expect it!"

Zheng Qing smiled and explained: "Brother Chen doesn't have to worry about it. Although it's a pity, the glaze introduced by the Great Yuezhi is much better, and it's normal to be loved by people."

If the ancients had the awareness of protecting national industry, they would not have squeezed the glass into the West. Zheng Qing would definitely understand what Chen Wanrong wanted to explain this truth. He would regret saying such words. It would be useless to just explain it to her. He just sighed. Chen Wanrong didn't say anything more, took off his coat, picked up feldspar and put it in his clothes.

Zheng Qing blinked her eyes and asked in confusion: "Brother Chen, what are you going to do?"

"Take it back!" Chen Wanrong blurted out without thinking.

Zheng Qing asked again: "Brother Chen, are you going to make glass?"

It was Yiren who knew him, Chen Wanrong nodded and said, "Yes! This glass is very difficult to build. I have to take some back and study it, and then find a way to build a workshop and produce it in large quantities."

The technical difficulty of glass manufacturing is much greater than that of making soap. This high temperature alone is enough to make Chen Wanrong a headache. To melt the ingredients of quartz sand, soda ash, feldspar and limestone, it takes a high temperature of 13 to 1677 to 100 degrees. Such a high temperature is naturally not a problem for modern society. In the Tang Dynasty, this was a very difficult technical problem. Once the temperature rises, the performance of the substance will change, and the problem of the furnace will arise.

Not to mention, if these problems are not solved, if they want to mass-produce glass in the Tang Dynasty, they would never dare to think about them.

It's okay to make something and use it yourself.

Zheng Qing is already familiar with the magic of glass and has long been longing for it. When she heard this, she could not help but: "Okay, okay! Brother Chen, what should I do? I will help you!" She stared at Chen Wanrong expectantly, for fear that Chen Wanrong would not agree.

Chen Wanrong could not refuse Yiren's kindness, and smiled and said, "I will naturally ask you for help."

Zheng Qing was relieved, smiled and helped Chen Wanrong pick up feldstones. She was extremely beautiful, and her every move was like a dancer's dance. The beauty was indescribable. Chen Wanrong felt itchy and whispered in her ear: "Qing..." and patted her face.

It meant that Zheng Qing wanted to kiss her, but Zheng Qing didn't understand. She gave him a blank look and said lightly: "Go! I'm not serious!"

If a man is serious at this time, he will be a failure. Chen Wanrong smiled and said, "Why not do it with beauty? Who told you that you are so beautiful?"

The compliment of the sweetheart is more important than anything else. Zheng Qing looked around and saw that there was no one, so she boldly said, "Close your eyes."

The good thing came true. Chen Wanrong closed his eyes as he said. Zheng Qing was brave enough to kiss Chen Wanrong's face. His pretty face was so shy that he blushed, and even the root of his neck was red. He couldn't help but lower his head.

Chen Wanrong opened her eyes happily, hugged her slender waist, and said proudly: "Qing, wait for me to make glass, I will build a laboratory. We are doing experiments, I will do it, and you will accompany me, and I will be satisfied!"

After coming to the Tang Dynasty for so long, Chen Wanrong has done a lot of things. It’s just because there is no testing method, and it can only rely on experience and estimates. If a laboratory can be built, it can be accurate. This is Chen Wanrong’s dream. If this is the case, the experiment will be done and the major events in life will be solved. What else can’t be satisfied?

Zheng Qing was so embarrassed that her heart was like a deer jumping. She still nodded gently. Yao nodded lightly from her nose and leaned on Chen Wanrong's shoulder involuntarily, which was very happy.

After a while of warmth, I picked up the feldspar, wrapped it up, put it on the horse, and went home with a horse.

As soon as she got home, she saw Mrs. Chen coming up and said with a smile: "Miss Zheng, haven't eaten yet? Come and have a meal, it's still hot!" In her eyes, Chen Wanrong is really jealous with a future daughter-in-law and no son.

"Auntie!" It feels good to give people care. Zheng Qing felt warm in her heart and gave Chen Wang's blessing.

Chen Wang hurriedly held it and shouted in the kitchen: "Second sister, please serve the meal to Miss Zheng." Her sister responded in the kitchen.

"Miss Zheng, go for dinner!" Chen Wangshi reminded Chen Wanrong, "Wanrong, you are really good. What are you doing in the early morning? You don't even come back to eat. Look at you, Miss Zheng's food is ruined, and your mother will settle the score with you."

Before he could pass the door, he protected his daughter-in-law. What else could Chen Wanrong say? He had to follow her words: "Mom, I understand, I won't run so far in the future."

"Wanrong, mom, help you carry it." Chen Wang grabbed the corner of his clothes and asked, "Wanrong, what are these?"

The mother and the two carried the bag into the house. Zheng Qing had originally entered, but before she could reach the door, she saw Chen Wang shut the door. Knowing that the mother and the son had something to say, she had to go to have a meal reluctantly.

"Mom, why are you closing the door?" Chen Wanrong felt a little surprised and asked casually.

Chen Wangshi stared at Chen Wanrong and asked: "Wanrong, mom, ask you, what did you do to Miss Zheng?"

Chen Wanrong was confused when he heard this, touched his forehead and asked, "Mom, what do you mean? I don't understand."

Chen Wang's face was not gentle at all, and his tone was still serious: "Look at Miss Zheng is very tired today. Have you done anything to her?"

Today I ran far and about an hour back and forth. Zheng Qing's delicate woman was not as strong as a man and was already tired. This is normal. Chen Wang was too worried and thought that Chen Wanrong had a physical invasion of Zheng Qing.

Chen Wanrong understood and smiled bitterly: "Mom, stop thinking about it, how could I do that?"

This is said very seriously, and it is not like telling lies. Chen Wang looked at Chen Wanrong for a while, and then hesitated and asked: "Wanrong, really didn't do it? Why do you think Miss Zheng is much tired than before?"

"We can run far!" Chen Wanrong said something and immediately realized something was wrong. When he set off today, he saw Zheng Qing's eyes red and slightly tired. He was immersed in the Five Animal Show at that time and didn't think about it. Now, after being reminded by Wang Chen, he immediately realized something was wrong and quickly changed his words: "Mom, I don't know this problem. Okay, I'll go and ask her."

He gave Chen Wanrong a blank look, and Chen Wangshi angrily said, "What are you going to ask? Are there some things you can ask?"

This makes sense. Women's private affairs will not be told to men. Even if it is a couple, they will be very knowledgeable. They can only tell them to their close friends. Chen Wanrong nodded and said, "I won't ask, mom, go and ask."

"I know!" Chen Wangshi was sure that Chen Wanrong did not do anything more than anything, so she felt relieved and said with a smile on her face: "Wanrong, don't worry about your character. Be kind to Miss Zheng, treat Miss Zheng with courtesy, and do not act randomly!"

Everyone understands the meaning of this sentence. Men and women are very attractive to men, but how can they be compared to love and affection? Chen Wanrong likes Zheng Qing from the bottom of his heart, so he naturally has to respect her. Even if he wants to do what a man should do, he must agree with Zheng Qing. Chen Wang's worries are unnecessary, and Chen Wanrong smiled and said, "Mom, don't worry! Can't you trust me?"

Chen Wang nodded and said, "Of course I can trust you, but you have to control yourself. What's the matter in this dress?"

Chen Wanrong opened his clothes and exposed the feldstone inside. Chen Wang looked at it and said, "Wanrong, what are you doing? This thing is useless except for curing diseases. After you have done so much, isn't my house a medicine shop?" Finally, he also gave a scolding sentence: "Wanrong, you are really, tiring these useless stones early in the morning has exhausted Miss Zheng."

"Mom, you don't know, this is a good thing. With feldspar, I can make the instruments I need, and Chen's chemical engineering will achieve greater development." Chen Wanrong patted feldspar and said confidently.

Although Chen Wangshi didn't believe that feldstone was of great use, Chen Wanrong's words were so sure that she couldn't refuse to believe them: "If you do whatever you want, you will be suitable. Go and have a meal quickly and keep it for you."

After responding, Chen Wanrong and Chen Wangshi left the house and went to the kitchen. They saw that Zheng Qing had already eaten, and smiled at Chen Wanrong, which was very sweet.

"Wanrong, you have dinner." Chen Wangshi ordered and said to Zheng Qing: "Miss Zheng, I have some work, I want you to help."

If your parents-in-law have something to do, how can Zheng Qing not do her best? She hurriedly stood up: "If you have something to do, just tell me, Zheng Qing will do her best."

"Miss Zheng is so good!" Chen Wang praised and took Zheng Qing's hand.

Chen Wanrong knew that she was going to ask about things and sat down to have breakfast. Before she finished eating a bowl of rice, she saw Zheng Qing hanging on Chen Wang's arm, smiling and full of joy on her eyebrows. Chen Wang came over quickly: "Wanrong, thank you Miss Zheng quickly! She is helping you so much!"
