Chapter 720: Colorless Glass
readx; readx; When Lu Chengqi was narcissistic, Gao Hao quietly walked in, saw such a "cute" Lu Chengqi, forced a smile, and stood aside without speaking. Lu Chengqi, www.biquge.info pen "Fun" pavilion, naturally put down his hand to measure his biceps, frowned, and said, "Gao Hao, what are you doing here?" ”
"Your Majesty, Tang Xun, the squire of the Ministry of Works, Shen Kuo, the director of the Ministry of Works, and Zheng Su Song, the superintendent of armaments, ask to see you."
Gao Ho forced a smile and lowered his head and said.
"What are they coming?" Lu Chengqi had a bad premonition, frowned and said, "Announce their audience." "Lu Chengqi has always attached importance to high-end scientific and technological talents, and this trio represents the cutting-edge power of Dashun's science and technology.
After Gao Hao withdrew, after a while, the door of the sun-facing vertical arch hall was dark, and three mermaids rushed in, bowing their heads: "See Your Majesty!" ”
Lu Chengqi waved his hand and said, "Zhongqing is flat, but if you have a face?" ”
At this time, Gao Ho took a few attendants and took the initiative to bring chairs to the three of them and served fragrant tea. After the three of them sat down, Tang Xun, who was old after all, said: "Your Majesty, the ministers led the students of the Royal University to develop a colorless glaze, comparable to the ...... of water jade" dudu1;
Lu Chengqi was taken aback, he knew that water jade was crystal, and it was out of their love for the jade of crystal that they gave it a very beautiful nickname, which means jade like water, and it is also said to be "transformed by the ice of a thousand years". The word water jade is the earliest and most frequently derived from the "Classic of Mountains and Seas": "Three hundred miles to the east, the mountain of the sun...... Polyhydro Jade"; "Danshan is out of Yan, and the southeast flows into Luoshui, which has a lot of water jade"; "Chase the water out of Yan, the north flow is injected into Wei, and there is a lot of water jade in it." Sima Xiangru "Shanglin Fu" said: "Water Yulei River". The crystal is named water jade, and the ancients valued the texture of "its crystal clear like water, and its hard as jade".
In addition, crystal is also known as water spirit, water blue, quartz, etc., all of which refer to pure crystal. Now Tang Xun said that he has developed a colorless glass, isn't that glass?
"Where's the sample?" Lu Chengqi didn't say much, he had to judge for himself whether it was glass or not. He knew that the method of firing glass was different from that of later generations of glass, so how did they fire glass? The history of firing glaze in ancient China, which can be traced back to the Western Zhou Dynasty, was obtained from the by-products produced during the casting of bronzes, which were refined and processed and then made into glaze. There are many colors of glaze, and the ancients also called it "five-color stone". By the Han Dynasty, the production level of glaze was quite mature. However, the smelting technology was in the hands of the royal family and nobles, and it has been kept secret. Because it was difficult for the people to obtain, people at that time regarded colored glass as even more precious than jade.
The ancient method of glaze is made by using "glazed stone" and "glazed mother" to fire. Glazed stone is a colored crystal material, glazed mother is a natural and artificially refined ancient formula, which can change the structure and physical properties of crystal, so that it has a significant improvement in shape, color and transparency.
The glass is made of quartz sand, soda ash, limestone, feldspar, etc., the raw materials of the two are different, how to achieve pure and colorless?
Soon, Lu Chengqi got the answer. I saw Tang Xun take out a round thing from his sleeve and carefully present it to Lu Chengqi. Lu Chengqi looked at it, and it turned out to be a glass ball-shaped thing. Under the tentacles, it is as cold as jade. Lu Chengqi carefully looked at this "colored glass" and found that except for some traces of polishing, it was really a solid color, like natural crystal. But whether it is glass or not, Lu Chengqi has no way to judge. dudu2;
After Lu Chengqi put down this "colored glass", he asked directly: "I want to know, how is this colorless colored glass fired?" ”
The three of them looked at each other at first, and then Shen Kuo said honestly: "Back to Your Majesty, the ministers fired the glaze, it was originally for His Majesty's birthday, I never thought that a student would forget to put the 'glazed mother', and the kiln fire was also fierce, and it was accidentally hit and made of this colorless glaze......"
Lu Chengqi understood, it turned out to be a beautiful mistake that made the glass come out. In this way, the glaze actually depends on the raw materials and preparation methods of the glaze mother, it is precisely because of the existence of the glaze mother, so that the ancient glaze and crystal and even the glass of the West, there are color changes and differences, but the firing method should be the same.
How could Lu Chengqi not know the wonderful use of this glass, and under the joy, he immediately took the rice paper, hastily drew a simple drawing, handed it to Tang Xun, and said: "Do you know the wonderful use of this concave lens and convex lens?" ”
Tang Xun looked at it for a while, only felt that these two mirrors, I didn't know what was unusual, and shook his head. Lu Chengqi said with a smile: "When this concave lens and convex lens are combined, they can be made into a thousand miles away, and there is nothing to hide." ”
"What?!" dudu3;
The three of them were taken aback, they must know that "clairvoyance" and "shunfeng ear" are both things in the legends of the Han people, and now they can be "made" by mortals, how can they not be shocked?
Lu Chengqi said solemnly: "How can you know if you don't experiment without experimenting?" I dare to say that it can definitely be made into a clairvoyant mirror. In the future, it will be indispensable to march and set up formations. If it is loaded on the Hongxiang-style rifle, it can improve the hit, and it is possible to pierce Yang two hundred paces away. ”
Su Song was the most stable of the three, and he was so shocked that he couldn't hold his tongue at this moment, and muttered: "If that's the case, wouldn't it be like a bag to take the head of the enemy army from it?" ”
Lu Chengqi laughed: "That's true, I will be loaded with a clairvoyant mirror and a carefully made musket, which is called a sniper rifle. Choose someone who can shoot and shoot officers on the battle line, and the battle will be decided in one fell swoop. "Lu Chengqi is not boasting, the army at this time relies on the command of officers to give full play to its combat effectiveness. Once the dragons are leaderless, they will naturally be defeated.
In addition, the silver-plated side of this colorless glass can be used as a mirror, and the hair can be seen. Sell it for a lot of profits. "How could Lu Chengqi forget the windfall profits of this glass mirror, this is a weapon to increase taxes!
Shen Kuo was deeply shocked: "How did Your Majesty know the use of this colorless glass?" ”
Lu Chengqi was shocked, and hurriedly said: "I once read a book from the West, which recorded this matter, so I learned about it. I thought it was a barbarian advocating myself, and I scoffed at it, but I didn't know how credible it was. He has used this excuse countless times, and he used it when he was interrogated and couldn't prove it, and these three people are already familiar with Lu Chengqi's excuse, and they are about to memorize it.
