back to ancient times to be emperor

Chapter 720 Colorless Glass
When Lu Chengqi was narcissistic, Gao Hao walked in quietly, saw such a "cute" Lu Chengqi, suppressed his smile, and stood aside without speaking.Lu Chengqi naturally put down the hand measuring his biceps, frowned and said, "Gao Hao, what are you doing here?"

"Reporting to Your Majesty, Tang Xun, Minister of the Ministry of Industry, Shen Kuo, Director of the Ministry of Industry, and Su Song, Supervisor of Military Weapons, are seeking to see you."

Gao Hao suppressed a smile, lowered his head and said.

"What are they here for?" Lu Chengqi had a bad feeling, frowned and said, "Show them an audience." Lu Chengqi has always attached great importance to high-end scientific and technological talents, and this trio represents Dashun's cutting-edge technological strength. It is certain that they will meet together. Something extraordinary happened.

After Gao Hao withdrew, not a while later, the gate of Xiangyang's Chuigong Palace was suddenly dark, and three people entered in a file, and Natou bowed: "See Your Majesty!"

Lu Chengqi waved his hand and said, "Everyone is flat, but what if you want to play in person?"

At this time, Gao Hao took a few servants and took the initiative to move chairs for the three of them and serve them tea.After the three of them sat down, Tang Xun, who was very qualified after all, said: "Your Majesty, the ministers and others led the students of the Royal University to develop a colorless colored glaze, which is comparable to water jade..."

Lu Chengqi was surprised. He knew that water jade was crystal. Out of their love for this kind of jade, crystal, they gave it a very beautiful and elegant name, which means jade like water, and it is also said to be "melted by thousands of years of ice".The word "Shuiyu" was first frequently used in "Shan Hai Jing": "Three hundred miles to the east, the mountain of Ritangting... has a lot of water jade"; Out of Yan, Beiliu flows into Wei, and there are many water jade in it."Sima Xiangru's "Shanglin Fu" said: "Water Yulei River".The crystal is named Shuiyu, and the ancients valued the texture of "it is as clear as water and as firm as jade".

In addition, crystal is also known as water essence, water jade, quartz, etc., all of which refer to pure crystal.Now that Tang Xun said that he has developed a colorless colored glaze, isn't that glass?

"Where is 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 colored glaze was different from that of later generations of glass, so how did they make glass?The history of firing colored glaze in ancient China can be traced back to the Western Zhou Dynasty. It was obtained from the by-products of bronze casting, refined and processed into colored glaze.There are various colors of colored glaze, and the ancients also called it "five-color stone".By the Han Dynasty, the production level of colored glaze was quite mature.However, the smelting technology is in the hands of the royal family and nobles, and has been kept secret.Because it was difficult to obtain among the people, people at that time even regarded colored glaze as more precious than jade.

The ancient glass is made by adding "glass stone" to "glass mother".Glass stone is a kind of colored crystal material. Glass mother is an ancient formula collected from nature and artificially refined. It can change the structure and physical characteristics of crystal, making it have obvious changes in shape, color and transparency. improve.

Glass is made of quartz sand, soda ash, limestone, feldspar, etc. The raw materials of the two are different. How can it be pure and colorless?
Soon, Lu Chengqi got the answer.Tang Xun took out a round object from his sleeve, and carefully presented it to Lu Chengqi.Lu Chengqi took a closer look, and it turned out to be something in the shape of a glass ball.Under the tentacles, it was as cold as jade.Lu Chengqi looked at this "glass" carefully, and found that except for some traces of polishing, it was really a pure color, just like a natural crystal.But whether it is glass or not, Lu Chengqi has no way of judging.

After putting down the "colored glass", Lu Chengqi asked directly: "I want to know, how is this colorless glass fired?"

The three people looked at each other first, and then Shen Kuo said honestly: "Reporting to Your Majesty, the ministers and others fired the colored glaze to present to His Majesty's birthday. I never thought that a student would forget to put the 'Liuli Mother', and the fire in the kiln became fiercer." , and made this colorless colored glaze by accident..."

Lu Chengqi understood that it was a beautiful mistake that made the glass come out.In this way, colored glaze actually depends on the raw materials and preparation methods of colored glaze mother. It is precisely because of the existence of colored glaze mother that ancient colored glaze, crystal, and even Western glass have color changes and differences. The method should be the same.

How could Lu Chengqi not know the magical effect of this glass, so delighted, he immediately took the rice paper, drew a sketch, handed it to Tang Xun and the others, and said, "Your gentlemen, do you know the magical effect of this concave lens and convex lens?"

Tang Xun looked at it for a while, but felt that there was something strange about the two mirrors, so he shook his head.Lu Chengqi smiled and said: "The combination of the concave lens and the convex lens can make a clairvoyance, and there is nothing to hide from thousands of miles away."

"what?!"

The three of them were taken aback. You must know that "clairvoyance" and "shunfeng ear" are both things in the legends of the Han people. Now they can be "made" by mortals. How can they not be surprised?
Lu Chengqi said solemnly: "Looking at things is the way to know, how can you know if you don't experiment? I dare say that it can definitely be made into a telescope. In the future, it will be indispensable for marching and deploying. If it is installed on a Hongxiang rifle, When the hit rate can be improved, it is not impossible to penetrate Yang two hundred steps away."

Su Song was the most stable of the three, and at this moment he was so shocked that he couldn't hold his tongue, and murmured: "If so, wouldn't it be like picking something out of a bag for Wanjun to take the enemy's head from it?"

Lu Chengqi laughed loudly: "That's true. I will call it a sniper rifle, which is equipped with a telescope and carefully crafted. Choose someone who can shoot, and shoot and kill officers on the battlefield, and the battle will be settled with one action. "Lu Chengqi is not exaggerating, the army at this time is only able to display its combat effectiveness under the command of officers.Once the dragons have no leader, they will naturally be defeated like a mountain.

"Besides, if you plate this colorless glass with silver on one side, you can turn it into a mirror, and you can see all the hairs on it. If you sell it, you can make a huge profit." How could Lu Chengqi forget the huge profits of this glass mirror? This is a tax increase The sharp weapon!

Shen Kuo was deeply shocked: "How did Your Majesty know the usage of this colorless colored glaze?"

Lu Chengqi was startled, and quickly came up with an excuse: "I once read a book from the West, which recorded this matter, so I knew it. I thought it was the barbarians who were advocating themselves, so I sneered at it, but I didn't know how much it was. Believable." He has used this excuse countless times, and he used it when he was questioned until he couldn't prove it. The three of them are already familiar with Lu Chengqi's excuse, and they are almost memorizing it.
