Chapter 202 Glass Glass and Crystal

……………………………………

Zhuge Liang's question in one sentence made Liu Hanshao a lot more discouraged.

yes, what else can I teach them? Friction electric palm? A finger of miracles? If you really dare to teach like this, you will definitely be teased by these two monsters. Ice for fire is a rarity, right? It's a pity that it's not cold enough now, and there's no ice cube to grind into a magnifying glass.

In the end, Liu Hanshao had no choice but to use his strength to crush him, and said irrefutably: "Confucius said, the master leads the door, and the cultivation is in the individual." Don't always ask what the master can teach you, but ask yourself more about what you have learned, do you understand? ”

Zhuge Liang muttered again: "Master, this is not what Confucius said, right?" ”

Liu Hanshao said maliciously: "The master said yes, that is." Why don't I send you to Confucius and ask him yourself? ”

Zhuge Liang shuddered and immediately said, "The apprentice knows, what the master said must be true." The master is above, please bow to the apprentice! ”

Foul words, what kind of monarch chooses the minister, the minister also chooses the king, if you want to accept an apprentice this year, you have to rely on strength, fortunately, my brother still has this "strength", no matter how evil you two are, you have to obediently kowtow to my brother and call the master. Liu Hanshao just wanted to look up to the sky and smile, but suddenly frowned again, foul words, what did my brother originally want to do when he came to the institute today? Let these two little rabbits get out of the way, and they actually forgot about it.

Oh yes, glass.

In Liu Hanshao's view, glass has reached the point where it has to be developed. Not to mention, Yuan Shao's small farewell, there is no glass on the window, only white silk screens can be used, the light transmittance is poor, and the wind is not blocked, if it is winter, it can only be blocked with thick curtains, the house is dark, even during the day, you have to light the lamp to boil oil, what is the difference between this and wearing a suit and a tourist shoes?

Moreover, Liu Hanshao still wants to sell super expensive clothes, but how can he use a bronze mirror to show people's beauty? If there were big glass mirrors, and those noble ladies wore new clothes, and stood in front of the mirror, they would not have to fall in love with themselves?

In the long run, glasses, bottles, plates, bowls, all of which are good things that can be exchanged for money. The most important thing is that if you can get a telescope, even if it is a monocular, it will be a sharp weapon to equip it with the army.

…………

Glass is not a rarity, dating back to more than 3,700 years BC. It is said that a Phoenician merchant ship was carrying trona along the sea, and after a large wave, the ship ran aground. The crew flocked to the beach, and the cold of the sea breeze made them decide to put the alkali blocks and firewood loaded on the boat together to make a fire to keep warm. After burning, someone suddenly discovered that after the alkali block and grit had been burned, it had become a crystal clear thing that had never been seen before.

Actually, that's glass!

In fact, this argument is not credible!

Sand is a silicon-based material, and when combined with alkali, it becomes the most primitive glass, but the melting point of "silica", the main component of glass, is about 1,700 degrees, and the melting point of sodium glass is about 1,400 degrees with sodium as a flux, and even if high-quality coal is used, the maximum temperature in an ordinary furnace is only about 600 degrees, not to mention the bonfire more than 3,000 years ago.

In China, it is called glaze, which is obtained from the by-product produced when the bronze is cast. The temperature required for casting bronze is extremely high, and there is no problem at all to melt the main component of glaze, "silica", and secondly, the formula of bronze requires adding lead and tin to copper, and barium is a symbiotic of ancient lead ore and cannot be separated, so the coexistence of lead and barium in ancient glazed glass is inevitable. In addition, the sand mold of the ancient sword casting contained a large amount of silica, so that the materials, temperature, and flux conditions for the formation of glaze were met, and everything else was naturally logical.

After refining and processing, the glaze is made of a variety of colors, and the ancients also called it "five-color stone", which is the stone used by Nuwa to mend the sky. In ancient times, because it was difficult for the people to obtain, people at that time even regarded glass as more precious than jade.

Regardless of the precedence dispute, whether it is glass, glass or crystal, its main component is silica. Whether it is glass or glass, almost all of them have color and are not very transparent. One is because the technology is not mature, and the other is because the conditions are limited, not to mention anything else, the melting temperature alone cannot meet the requirements.

In addition, China, since ancient times, advocating jade, whether ceramic or glass, are going to the appearance of jade, can imitate jade belongs to the boutique, do not pay attention to transparency, first pay attention to gloss, whether warm and moist like jade. Then make it a thing for the powerful to play with, first pay attention to the beautiful appearance, and then talk about whether it is practical or not.

To put it to the point, this is actually a kind of deviation, just like the jacquard machine transformed by Ma Jun in the original history, the elixir of immortality refined by the warlocks, and the firing of glass, the first consideration is to serve the powerful.

What later generations are fighting for is culture, skills, reality and romance, and a long-standing era.

…………

But will Liu Hanshao pay attention to these?

He just wanted to find some craftsmen who could make glass, and then research the glass and put it into practice!

Like black powder, it is used to make fireworks in the east and guns in the west. But now, even if its glass is longer than glass, let's use it as a telescope, let them continue to make glass beads, and play slowly.

Isn't it happy?

When it comes to making glass, Liu Hanshao naturally doesn't understand, but Xuezha insists that it seems that many things are nothing more than burning, soaking, boiling, and drying, adding or subtracting various things back and forth to the inside, and doing all kinds of experiments.

Originally, Liu Hanshao first thought of Liu Dagen's son, Liu Zi, but Liu Zi changed from a pottery barrel to burn white porcelain, and from a white porcelain burner to cement burning, and now he has changed to burn toilets and floor tiles. Even if you gather wool, you can't catch a sheep, right? So Liu Hanshao wanted to come to the research institute to see if there was a scientific research group that studied firing glass, but Zheng Hun and Ma Jun were scared away early, not to mention, and they were calculated by Zhuge Liang and Sima Yi, the two little turtle calves.

Or...... Let these two little bunnies go to the glass?

It took thousands of years to produce such two demon heads, isn't it a bit tyrannical to use them to do this?

Seeing that Liu Hanshao was a little confused, a little sad, a little helpless and in a dilemma, Yang Xiu asked cautiously: "Han Shao, what are you doing when you come to the institute today?" ”

Liu Hanshao said truthfully: "Brother just wants to come and see if there is a scientific research group studying Liuli here." ”

"Han Shao needs glass?"

Seeing Liu Hanshao nodding, Yang Xiu said again: "Then why did you come here, we are in Luoyang, the land of Beijing, what kind of craftsmen are you looking for?" Not to mention other places, even if Chen Jiangzuo is there, he should be able to find someone. ”

Chen Zhao was a master craftsman in the past, but now he is divided into the Internal Affairs Department, and he is busy building small bezel fields with people all day long.

A word woke up the person in the dream, Liu Hanshao smiled and asked, "This thing is simple?" ”

"Easy!"

Yang Xiu said in a big way: "You can leave this matter to the minister, and the quasi-guarantee will find all the people for you, so that you are satisfied." ”

"Cheng, I'll leave it to you!"

Things have come to an eyebrow, Liu Hanshao is in a happy mood, and he is not willing to go to the research institute anymore, this is a sad place to resist himself.

turned around to leave, and suddenly heard Zhuge Liang ask, "Master, are you just leaving?" Today...... Don't plan to teach your apprentices yet? ”

Liu Hanshao's head was black, and his tangled mood climbed back to his eyebrows.

"You two, have you learned Hanyu Pinyin?"

Zhuge Liang and Sima Yi nodded together.

"Can you memorize the multiplication formula?"

Zhuge Liang and Sima Yi nodded together again.

"Abacus Mantra ......"

This time, without waiting for Liu Hanshao to finish asking, in addition to nodding the two little monsters, Zhuge Liang even opened his mouth to recite it.

"One up, two on two, three on three...... Five to four, two to five to three......"

Hurriedly waving his hand, Liu Hanshao stopped Zhuge Liang from continuing to recite in a ostentatious manner, and asked, "Do you two have a Beibi dictionary?" ”

Sima Yi said truthfully: "Yes." I'm done. 3,700 words, all recognized. ”

Liu Hanshao almost vomited out an old blood, and he may not be able to know all the words in the dictionary after graduating from Beibi Primary School, but these two little babies have only studied for a few days, and there is nothing to stump them, and it is really painful to be a master for demons!

"Confucius said, the master leads the door, and the practice is in the individual. The two of you are going to mess around at the institute first...... No, I studied at the graduate school first! Be sure to learn more, watch more, and think more. Other brothers and sisters are all engaged in research and invention, and the two of you will each invent a thing and show it to the teacher, and then arrange your homework according to your interests, hobbies, and natural abilities, understand? ”

Sima Yi said with some frustration: "I understand. ”

Zhuge Liang asked unwillingly: "Master, when will you come to the institute again?" If you encounter a problem when you are engaged in invention, how can I ask you for advice? ”

Liu Hanshao used the greatest patience to explain: "The master is busy, and it is not certain when he can come." If you have any questions, you can ask the senior brothers and sisters for advice first, or you can go to the master at any time, the doors of Yong'an Palace and Mingguang Hall are always open to you, okay? ”

After saying that, he didn't dare to wait for two small troubles to come up with new problems, Liu Hanshao turned around and ran away with a group of people.

Looking at the unreliable master in the distance, Sima Yi asked worriedly: "Does the master not want to see us?" ”

Don't look at Zhuge Liang is a few months younger than Sima Yi, but he is big since he was a child, and Sima Yi has been strictly controlled by his father since he was a child, so when the two are together, it seems that Zhuge Liang is the leader.

At this time, I watched Zhuge Liang put one hand on Sima Yi's shoulder, one foot raised and kept swaying, and said nonchalantly: "How can you see it?" ”

"Why didn't the master teach us how to govern the country?"

"Do you still need to teach how to govern the country? Make the best use of your talents and make the best use of your resources, won't you? If you don't even know this, you will be obedient in the future, and my brother will teach you. ”

Sima Yi was stunned for a moment and retorted: "It seems that I am the senior brother, right?" ”

Zhuge Liang said disdainfully: "In the early years, when the master, uncle, and aunt worshipped the master, they said that they should not be ranked by age, but by their skills. Do you think you're better than me? ”

"It's not necessarily strong...... It's not necessarily bad. ”

Sima Yi said, suddenly drooping his shoulders, Zhuge Liang lost his support, and suddenly leaned his body, seeing that he was about to perform again......
