Fall In Love with the Technology Tree
Chapter 23: paper and pen
A Sheng played with the pencil in his hand. From the outside, it was no different from the pencils of later generations: a hexagonal wooden bar with a thin cylindrical stone grinding body inlaid in the middle. Sharpen it with a razor blade, and you can draw thick black handwriting on the paper.
She originally thought that she would use wicker and charcoal to make hard pens, but she never thought that the history of Chinese people using graphite is much earlier than the history of using pine smoke ink. It's just that hard pens have not become the mainstream of writing, and graphite and water grinding are just an inferior ink.
Artisan Ai stood in front of her several cases with her hands down, her face full of frost and frost seemed to have the chill of the outdoor autumn wind.
"Look, I've only written ten words, and then I need to sharpen again. How long can such a pen last? How much time does it take to sharpen during use? And—" She reached out and wiped it on the white paper. The graphite powder was smeared, and the handwriting was blurred immediately. "look!"
Graphite pens have some drawbacks, otherwise they would not be in a weak position and be crushed by soft pens. The graphite pens made by Craftsman Ai are already of the highest quality compared to the products of the same generation. At least he knows that the wood needs to be boiled to make it easier to cut with a knife, and the graphite is also compacted.
Jiang Ai was expressionless, but his eyes flashed twice. "Little Lang-kun has a gully in his heart, so don't spend any time here."
"Mixed clay. It doesn't have to be high-quality clay, ordinary clay can be tried. Different proportions of clay and graphite can make different hardness, corresponding to different uses. Add water and mix Compacting into the mold and then calcining at high temperature will make the texture more compact.”
The man's expression instantly lit up and became energetic: "Besides clay, do you need to try anything else? For example, spices, iron powder, charcoal powder." The spirit of the experiment was burning.
"Don't.... I told you, the control variable method, you can't chew too much."
"Oh." Suddenly lost.
"And you have to remember a principle." Ah Sheng threw the pencil on the table, "This consumable, the simpler the craft, the better, and the cheaper the material, the better. I want to give Children in the nursery hall and people in other courtyards use it for reading. Iron and spices are added to it? Huh? Are they also mixed with gold?"
Her cynicism made Jiang Ai's face tense. The big man who has been rolling around in the workshop for twenty years is mocked by a doll, and even those with a little self-esteem can't stand up or down. But what she said was right. Craftsman Ai passed the test, but often went wrong on some directional issues.
"Besides, don't use riveting to inlay wood. The small graphite pen shell is also worth showing off your skills? Find a better adhesive and use it sooner or later in semi-mechanized production arrive."
Adhesive, mechanization, these two words are not the first time Jiang Ai heard. In fact, the technique of pressing paper by the metal roller set provided by Ah Sheng has long made him full of admiration for the concept of "mechanization", which is why he signed a death deed with Cao Sheng after saving enough money for redemption.
He prides himself on being a genius. But since he came under the name of the little Langjun of the Cao family, his knowledge of his profession has been refreshed every day. She is not a professional craftsman, but everything she knows and thinks has an oppressive forward-looking vision.
No matter how arrogant he is on the face, he is still very clear in his heart: following this person, maybe he can be famous in history like Cai Lun and Lu Ban.
"Winter is coming, if there is anything missing at home, just tell me. Although there is a lot of work, don't stay up late, your body is the heaviest." He was especially generous, on the same level as the Shi family and the Zang family.
"There's nothing missing here."
"The servants at home, I asked them to take turns to help in the workshop. If you like it, feel free to ask me for someone."
"Oh! They are all mediocre!"
A Sheng chuckled: "That's fine." In the future, she will let the orphans who have gone through elementary education, there will always be someone who can satisfy the craftsman Ai.
After the muscular man stepped back, Ah Sheng's smile could no longer be suppressed.
"The master is very happy?" Luo Chi asked, "I pretended to be serious in front of him."
A Sheng picked up the pencil and looked over it over and over. The technological progress was second, and the appearance alone made her feel friendly. "Actually, he mixed it with other ingredients, not clay, but wood flour or glue. Pure graphite is much more brittle than this. And this one is close to 12B."
Luo Chi didn't understand the word "12B", so he smiled and pretended to be well-behaved. You can often hear new words around Xiao Langjun. It doesn't matter if you don't understand it once, you will understand it after listening to it a lot.
Asheng is in high spirits today. "Anyone of you can draw?" She asked while rummaging among the sample papers made in the workshop, and picked out one of the thickest hard paper with matte fibers.
This question is out of scope. How could someone who had been sold as a slave since childhood could draw. At this time, painting must at least require pen, ink and paper, which is what the people at the bottom can afford.
A Sheng was splashed with a basin of cold water, and glumly threw the pencil and cardboard to Yan Wen who served behind him. "Forget it, just take it as if I didn't ask. Help me get my coat, and I have to go back to my home to study today. Where's my brother? Going to harm Zhao Weng's Yuncai early in the morning?"
Rucai, or Hu Cai, was a seed sent by my grandfather's friend from the Northwest. Ah Sheng thought it was something rare at first, but when he saw it, well, it was rape! When you have rapeseed, you don't need to press the beans. Next year, you can eat rapeseed oil. It's a delight to think about.
The autumn wind has already started. Most of the fields on the farm are intercropped with soybeans and winter wheat. The same relatively cold-resistant rapeseed was planted beside the ridge of the experimental field. Ah Sheng is not specialized in agriculture, but she knows that soybean has nitrogen fixation effect, and interplanting the staple food is conducive to high yield; while **** is one of the more common vegetables in winter.
"What scourge?" Little brother Geely perfectly explained what is meant by "say Cao Cao and Cao Cao will arrive", he strode in from the outside, and threw a pear to Ah Sheng, "Eat it quickly, you know. You like this."
Well, instead of harming rape, it’s time to harm fruit trees.
Before the chauffeur from Feitinghou Mansion arrived, Ah Sheng nibbled the ripe pears, and then took his companions and brother to the city by car.
The carriage was a status symbol at this time. There were clear regulations on the number of horses pulling the carriage, the umbrella cover used for the carriage, and the material of the decoration. For the Cao family, who started out as eunuchs, it would be too ostentatious for a child to ride a carriage. Therefore, Ah Sheng and his elder brother rode in an ox carriage. The bullock cart is spacious and can be modified and installed on the wall at will, but it just walks slowly.
It was about ten o'clock in the morning when I returned to Feitinghou Mansion.
Cao Teng inspected the twins' last homework, and taught a few common etiquette common sense, and it was time for lunch.
…”
“Geely is also learning more and more enlightened in other courtyards.”
"I heard Zhao Weng say that most of the officials...what the hell, the wild goose plucks hairs, and the poor are the commoners in the end." The little brother is still too young, but there is a straightness in his nature. "Eunuchs, foreign relatives, the most greedy!"
Cao Teng's expression stiffened.
A Sheng hurriedly said: "Brother is wrong, the family is the most greedy. Whose family is born rich? Really honest officials are often unable to inherit their families, and their descendants can only rely on poverty. Farming to make a living, in the face of natural and man-made disasters, either starve to death or become a slave. Even learning is delayed, and gradually fewer talents will be born. But everyone who is rich now lies on the ointment accumulated by their ancestors. Brother, don't look at the family. The children claim to be more noble, that is because their ancestors have accumulated wealth, land, fame, and connections, and they no longer need to worry about these things in their generation."
The primitive accumulation of capital has permeated blood and sweat. And Cao Teng and Cao Song are still at the step of primitive accumulation. A Sheng spends years in the warehouse shopping for treasures, and from the changes in the items inside, it can be inferred that Cao Song is not clean, and Cao Teng probably acquiesced. The background of the Cao family is too thin, the land needs to be accumulated, the servants and servants need to be cultivated, and human relationships need to be exchanged. As long as it's not something that hurts the world, the gray income will be taken. After all, the Eastern Han Dynasty is no better than the later generations.
If this is the heyday of the dynasty Ah Sheng, he may still feel guilty for digging the corner of the country. But right now, the Eastern Han Dynasty is slipping in the direction of collapse. Intellectually corrupt Confucianism is on the rise, politically it has been messed up by eunuchs and relatives, and the channel for the rise of the bottom is monopolized by noble families. Rescue of the court. This broken house needs to be repaired, it is better to tear it down and rebuild it. Moreover, her brother is Cao Cao!
Cao Teng smashed the table and pulled Ah Sheng's thoughts back. "Enough! You...you two...you can't say this outside!"
The grandfather was angry, and the twins quickly tacitly fell to the ground. "We were wrong and dared not say it outside, only with my grandfather."
Cao Teng is still panting. "It's only four years old after the new year, so I don't worry about it. It's okay to grow up?! Geely is too straight, Ruyi... eyes are too vicious."
A Sheng blinked innocently. Although what she said was a bit extreme, it also made sense. "I understand, I understand. Brother, we are a vested interest group."
Cao Cao lowered his head in thought, thinking about the phrase "Vested Interest Group".
Cao Teng gave up and threw the bamboo slip: "Eat!"
