The First Family of Tang Dynasty

However, seeing the straw being washed and soaked, Cheng Chubi thought of the abandoned small paper mill in his township.

That was in the 1980s. Due to the inconvenience of transportation, many places in the Southwest had their own paper mills with small workshops.

And the raw materials they use are exactly these things. Although the quality of the paper produced is average, at least it can be written.

Cheng Chubi still remembers an uncle who was a technician in a paper mill. It is said that he was a lecturer who had made a mistake and was delegated to a university.

After checking the veins of the paper mills in the township, a certain proportion of bark and a large amount of cellulose-rich raw materials such as reeds were added to the grain stalks.

The made paper circuit has great hardness and strength. The reason why the impression is so clear is that when I was young, the most annoying thing for big guys was to use the homework book ass.

Because the paper is too hard and tough, the dolls with small arms and legs won't be able to tear at all.

The paper source of the workbook is the piece of paper produced by the township paper mill.

Later, the pollution was too serious because the original village materials such as straw were used to make paper. In the end, the small paper mills were either shut down or merged, and a green mountain was returned to their hometown.

After Cheng Chubi graduated from university, he went to the paper mill with a former classmate to recall his youth. After all, he did many heroic deeds such as peeing in the bubble pool.

Uncle Fu and Cheng Hu, the housekeeper, noticed the strangeness of their third son, and stood dumbly by the side of the pool where the smell was rushing, with weird smiles on their faces.

Cheng Hu was about to speak when he saw the housekeeper Fu Uncle waved his hand and whispered.

"Don't disturb the third son. When the third son has a strange smile on his face, generally speaking, he has an idea or inspiration."

Hearing the words of Uncle Fu, the housekeeper, Cheng Hu smashed his mouth and looked at the sly smile of the third son, always feeling that something was wrong.

Uncle Fu, the housekeeper, smiled comfortably and peacefully, quietly and authentically.

"Our old Cheng family, the eldest son and the second son are pure and honest, but the third son is exactly the same as the old man, um...are all good people."

Cheng Hu's head clicked quickly, and his heart was straight. What this said... Who is the master, can I not know?

However, the two eldest sons and the second sons have true qualities, well, I don't know how to describe them.

If the master is coarse and fine, then the eldest son and the second son are hardly thin in the thick, the eldest son is better, the second son is a real person.

However, Uncle Fu was able to praise the third son to this level, coupled with the various deeds related to the top Changan son of the third son over the past year or so. Gee...

I am afraid that there is really a tendency for blue to be better than blue, and it can be regarded as a follow-up person from the old Cheng family.

The smile on Cheng Chubi's face finally gradually closed. "Cheng Hu, are there pens, inks, papers and inkstones here?"

"Yes, please also ask the third son to come with the villain." Cheng Hu quickly put aside the messy thoughts and strode forward to lead the way.

However, because he didn't bring a quill pen, Cheng Chubi, who could only write simplified Chinese characters in childlike style with a brush, simply let the housekeeper Fu Uncle go into battle.

And he was whispering and crooked beside him, and as Cheng Chubi dictated according to his memory, Fu Shu, the housekeeper, was struggling to transcribe the words of the third son.

Cheng Chubi took the copy of the paper-making process and methods that Uncle Fu had copied, and after looking at it carefully for a long time, he nodded in satisfaction.

Ancient man-made paper is pounded, and plant ash is used for soaking, which has insufficient alkalinity.

Therefore, Cheng Chubi decided to adopt the method of later generations, using lime to soak, and let them make a big grinding disc, and use the big grinding disc to grind the pulp.

In summary, it is crushing, soaking, cooking, refining, screening...

"By the way, there is still a matching ratio left on me. Straw accounts for 60%, and this reed accounts for 40%.

It should probably be this ratio. You can try one or two according to the process I gave you. "

Cheng Hu, who has been in charge of the old Cheng's papermaking workshop, saw that this production process was similar to his own, but there were several differences.

He couldn't help looking at the third son who had uttered these things almost without thinking, with his eyes full of awe and authenticity.

"San Gongzi, did you get this recipe from Xuancheng?"

Cheng Chubi opened his mouth. Although he was not happy that Cheng Hu looked down upon himself so much, Cheng Chubi was too lazy to explain.

He smiled inexplicably. "Don't ask too much, do as I tell you, I hope I can see the paper pattern before I leave Chang'an and return to Lishan."

"San Gongzi, don't worry, you will definitely not miss your important event." Cheng Hu immediately replied loudly with his head upright.

Hearing Cheng Hu's energetic answer, Cheng Chubi nodded in satisfaction, and finally left with confidence.

Lao Cheng's family members are more pragmatic, but when they do things, they will never be sloppy. One is one, two is two.

After leaving the paper mill, Cheng Chubi raised his head and glanced at the sky. He had to rush back to Chang'an City to see the tinsmith again.

Because the pewter ingots he had developed before were delivered today.

"Hey... I didn't expect that I would have such a day of conscientious work and painstaking efforts to run for others."

Cheng Chubi shook his head, really wishing to catch the prince of ribs and let him see how hard he was.

Let him understand the sacrifice that his good brother made for him.

As a result, I stayed in Chang'an these days and didn't even have time to play cards.

Hmm... the card friends that I cultivated are either still far away in the Qinghai land, or staying in the Lishan Tangquan Palace, soaking in the hot spring and eating dried fish.

Only oneself is the only one who is exhausted, not to give the Michelin Wei Wangzhi an eye, but to run around for the reputation of the Prince of Ribs.

Several lead ingots with exactly the same diameter and height are placed in front of them~www.ltnovel.com~ The cross section is about one centimeter and the height is about three centimeters.

In addition, on one side, there is a recessed groove, which is to prevent it from moving when it is used...

After all, the font copied in the regular script of this era is of this size.

Therefore, the lead tin ingot made by the gray-bearded tinsmith met Cheng Chubi's requirements.

"According to your instructions, San Gongzi, a total of five proportions of lead-tin ingots were made."

"The ratio of lead to tin ranges from three to seven, four to five, five to five, to six to four and seven to three.

Among them, this is the one with moderate hardness and the highest wear resistance..."

Cheng Chubi took the lead tin ingot that the tinsmith had said, and rubbed it **** the tribute paper for a long time. After examining it carefully, he nodded slightly with satisfaction.

Then he picked up a carving knife and scribbled **** the pewter ingot. After the first cut, Cheng Chubi felt a very comfortable feeling.
