Chapter XXV

Su You made Shi Da burn a pottery mouth, with only a small opening at the front end, and a porcelain plate with a round bamboo stick pressed out of a round groove.

Then make a pump with bamboo, put the sleeve on the pump, mix the clay with graphite to make black mud, squeeze the graphite mud on the small groove of the porcelain plate like squeezing toothpaste through the small hole of the pump, and send it to the kiln to burn with the pottery bowl.

It is also according to different proportions of more than a dozen kinds, and after firing, they are experimented on the pottery bowl one by one.

No way, the current writing paper is too soft to withstand the tip of a pencil.

However, I finally burned a suitable pencil lead and wrote down the ratio of various blacknesses.

Cheng Wenying finished reading the mud of the seal, and his confidence increased by another point, and he came to look at the things that Su You had made up, and asked, "Virtuous nephew, what is this?" ”

Su You said: "This, I call it a pencil." ”

Cheng Wen said curiously: "It's obviously ......"

After speaking, he suddenly woke up and said in a low voice: "Understood, misleading outsiders, right?" The scratches on this clay pot really look like lead marks. ”

After speaking, he looked at the refill, and said, "This is too thin to hold." ”

Su You folded a branch, asked Shi Da to cut it in half, cleaned up the veins in it, just enough to clip a piece of refill into it, then coated with sawdust and glue, clamped the refill, and after setting it on fire and drying it, scraped the skin smooth, cut out the nib, and smiled at Cheng Wenying: "Uncle, look, that's it." ”

Cheng Wenying took a piece of pottery and lightly scratched it on the pottery piece with a brush: "It's not easy to use." ”

Su You smiled and took the pencil, put the pottery shard on the table, and wrote on it, "The sun is at the end of the mountain, and the Yellow River flows into the sea." Ten words, he said: "Uncle, this should be used like this." ”

Cheng Wenying said with a smile: "That's not bad, at least the words are small, saving paper, ouch can bear you this paper is not easy to find." ”

Su You said: "Indeed, so the paper also has to be transformed. ”

Cheng Wenying was holding a water cup and wanted to drink saliva, and when he heard the words, he felt that his temples began to tighten again: "Virtuous nephew, according to your meaning, should we go to the paper mill again?" The old man used to be really laid-back......"

Su You said: "If there is a kind of paper that can be printed on both sides......"

Cheng Wenying put the cup on the table: "Then what else are you talking about?!" Hurry up! ”

Su You said: "Wait, I'll bring some Guanyin mud powder." ”

I brought a basket of the finest Guanyin mud powder, said goodbye to Shi Dongxiu, and made an appointment to bring someone from the bookstore to make the printing embryo tomorrow.

Su You and Cheng Wenying rushed to the Cheng family's paper workshop again.

Paper production requires a lot of water, so it is generally near a stream.

The papermaking workshop repairs bamboo forests, and the environment is very beautiful, that is, you can smell a smell from afar.

Su You thought to himself, maybe it's time to make a few masks.

The foreman of the paper workshop was Lao Xu, and when he saw the owner coming over, he thought something was wrong, and when he inquired, the young master of the Su family wanted to conduct an experiment.

The new paper still starts with experimentation.

Su You asked Lao Xu to drag a large vat, the equipment is almost the same, the first difference, Su You added some Guanyin soil mud to the pulp, accounting for about 20% of the pulp.

After the worker mixes the suspension, the paper is manipulated.

The second difference is in the number of times the paper is operated, the new method is doubled compared with the past, that is, the theoretical thickness of the final paper will be twice as thick as the normal paper.

And then the third difference, Su You did not ask the workers to stick the paper to the wall, but spread a muslin cloth on the wooden board, spread the paper, pressed the muslin cloth, the wooden board, and then pressed the stone slab.

In this way, the paper was processed one by one, and after a while, all the stone slabs on the small dam in the workshop were used up.

Then Su You had the workers raise a fire under the stone case and roast it.

Soon, a new style of paper came out.

This paper has been pressed, and the thickness is still about the same as that of rice paper, but it is obviously much tighter and much wider than rice paper.

Moreover, with the addition of Guanyin soil, the whiteness has also increased a lot.

The paper is also printed with a fine cloth pattern.

Su You then asked the workers to polish the paper surface with smooth pebbles, and then remove the fine powder attached to the surface, and the white paper became smoother.

The fibers are covered by Guanyin clay powder, and there are almost no traces to be seen.

Su You handed the paper to Cheng Wenying: "Uncle in-law, look." ”

Cheng Wen should be an expert, and he can see the usefulness of this paper at a glance: "Virtuous nephew, you want to deceive me again, this paper can be printed on both sides, and it is also excellent for book covers." But you're afraid it's for your weird pencil, right? ”

Su You smiled: "I can't hide anything from you, you see." ”

After speaking, he took a pencil and wrote on the paper, "If you want to be poor, go to the next level." Then he handed the pen to Cheng Wenying: "Uncle in-law, you can try it." ”

Cheng Wen should test two words, laughed and waved his hand: "No, no, it seems that this pencil calligraphy has to be practiced alone." The word old man can't even compare to your five-year-old baby! You are suitable for children, you can only write small characters, not large characters. ”

Su You smiled: "It's true, but this paper has another big benefit." ”

After speaking, he picked up a cooking cake on the table, pulled off a piece and wiped it on the word, and Cheng Wenying's two ugly words disappeared, and there was no trace of it.

Su You smiled: "The benefit of this thing is not in literature, but in the workshop. ”

It was Cheng Wenying's turn again, and after coming back to his senses, he hurriedly grabbed the cooking cake and pencil and observed it carefully, and only after a while did he say in surprise: "What is this?" ”

Su You pursed his mouth and said, "In this way, put away the paper first, and then show it to the in-law when you go back." ”

Roll up the paper, and then return to the city.

When he came to the study, Su You took a newly made ruler, compass, triangle, and caliper, took a pot lid, and said, "Uncle in-law, now I'll show you a demonstration." ”

Even the cassette tape was drawn, and soon, a picture of the lid of the pot was displayed on the white paper.

Standard engineering drawing, three views, top view, front view, the lid of the pot without a left view, then draw a sectional drawing.

A variety of detailed parameters indicate all the subtle dimensions of the lid.

Lao Yu and Lao Han came over to report the progress of the day's work, and when they saw this drawing, they immediately understood the benefits: "Yo! This French drawing is so small that with this French drawing and our small ruler, the potter can make an exact lid! ”

Lao Yu happily picked up the caliper and compared the numbers on the drawing while measuring the lid of the pot: "Wonderful! Wonderful! In the past, French drawings, drawings are drawings, text descriptions are text descriptions, where is so clear at a glance! ”

Su You said: "This set of methods is not used by people like you, and all the laws are in your hearts, so as the master said, 'Do what you want from your heart, and don't go beyond the distance.'" ’”

"But to reach the level of yours, it is the work of decades of obscenity. And this set of methods is to let the big workers leave the pattern, so that all the small workers can make the same thing as the big worker according to the assistance of the pattern and measuring tools, and you can free up your hands to be more refined, which is the value of this method! ”

Lao Yu and Lao Han were shocked, Lao Han was fine, Lao Yu saluted Su You and said: "Lao Gong is my two unsuccessful sons, Yu is greater than two, thank you Mr. Xiao." ”

Cheng Wenying thought deeper: "Back then, the master passed down the poems and books, and there was no class of teaching, so that my Chinese etiquette and religion could be passed on...... I'm afraid it's ......."

After saying that, there are some bad words, and I think it is ridiculous to compare a five-year-old child with a master.

Su You said: "I don't dare to compare my master, Su You just thinks that I am so skillful in the Song Dynasty, and I have lost a lot of them by word of mouth for thousands of years." For example, Luban's flying wooden bird, rat trap man, such as Tang Mo's knife-shaped system, such as Zhuge Wood Ox Flowing Horse...... It's a shame. ”

Cheng Wenying breathed a sigh of relief, his heart was fine, if it was really deliberately done by this nephew, his heart would be a little boundless.

After eating, Cheng Wenying completely relaxed, Su You's actions returned to normal, this kid is a glutton!

He's directing Mama Li and Chef Zhou to make kimchi!

The big mustard greens and ginger that are special products in southern Sichuan were made a lot of Su You in the vegetable garden yesterday, and now they are wilted.

Watching Su You use large pots of snow salt to make brine, Cheng Wenying was very distressed.

It's not that I'm sorry for the money, it's the effort I spent before.
