The two laughed loudly and continued to look at the things used in papermaking.

At this time, the two people came to stand in front of a large container.

The large container in front of you is composed of two parts. The lower part looks like a huge earthen pot turned upside down and has a mouth. The upper part is a large wooden barrel about one foot high.

"This is the Hesitation Foot Fire. Put the soaked bamboo into the Hesitation bucket, add lime, and cook it for eight days and eight nights. Using this artifact, the paper produced will be as white as jade."

…

"This is drying by fire. The wet paper is pasted on the wall one by one. Two rows of adobe bricks are erected with an empty space in the middle to form an alley. As long as you pile firewood and light a fire in the alley, after the temperature of the adobe bricks rises, the wet paper will

It is dried. After drying, it is peeled off to make paper."

…

Li Shisan suddenly realized, "I didn't understand what it was used for before, and I was confused. Only when I knew it did I understand the truth. It's really like a leaf blocking the eye."

Ni Tu nodded. It's not that people are unintelligent at this time, but their vision and thinking are blocked. This is like a layer of window paper, as long as you poke it open, you can figure it out.

The two designed it again and added some processes to ensure that each process was isolated and secrets were not leaked.

In order to make himself more beautiful and outstanding, Ni Tu came up with many cosmetic and beauty techniques. Similarly, in order to make paper more in line with people's requirements, Ni Tu constantly searched for new paper processing and beauty techniques.

The usual method used to deal with rough and uneven paper surfaces is calendering. After the calendering process, the paper surface not only becomes smooth and glossy, but also increases the density between the fibers in the paper, making the paper tougher.

Follow up with enhancement.

Calendering can be either single-sided or double-sided. Paper with double-sided calendering is mostly thicker paper.

The intertwined fibers in the paper create many gaps. If it is used directly for writing or printing, the ink will penetrate through the gaps and smear the back of the paper. Calendering is good, but it cannot completely solve this problem. If it can

Apply foundation on the paper - applying a layer of white powder will not only fill all the gaps, but also further improve the smoothness and whiteness of the paper.

The way to apply powder on paper, what Ni Tu thought of was to mix white powder with viscose liquid and then apply it evenly on the paper surface with a brush. The white powder may be a type of chalky lime with the chemical composition of calcium carbonate or calcium oxide. White powder

Colored powder can also be added to it, so that it becomes colored powder paper.

It is not easy to apply the brush evenly, and it is also troublesome, so Ni Tu added white powder directly to the paper pulp after repeated experiments. The paper he produced not only has powder on the surface, but also the inside of the paper is filled with powder. This kind of paper is

It is somewhat similar to the industrial paper of the previous life.

Ni Tu knew that paper without characteristics and system would not be able to make a name for itself as a brand, so he simply developed different papers that were commonly used in his previous life.

Ni Tu also took the opportunity to create translucent paper that could be used to copy calligraphy and painting, paper with various floral scents or dark background patterns, hard paper that melted wax to make oil-paper umbrellas, and lacquered paper that could be used to make fans.

In order to ensure the smoothness of the paper, Ni Tu even remembered the slang saying "Master Cai's slider will not stick to our curtains". The slider is the carambola juice. When the paper pulp is even, add the carambola juice and magically make it smooth.

The paper is flat and smooth.

After asking the craftsmen around, they found out that this sentence might have been forced upon Cai Lun by a later generation.

The paper that has been processed and beautified in this way has its own appearance, whether it is smooth and smooth, or colorful, which is refreshing.

After several days of hard work day and night, typesetting, printing, proofreading and binding.

Printed on newly made paper using movable type, the entire paper version of the Book of Songs finally appeared before our eyes.

Smelling the long-lost aroma of the book, feeling the soft and thick feel, and gently flipping through the manuscript, Ni Tu's heart was filled with excitement. The paper version of the manuscript was so common in his previous life, and its importance could almost be ignored.

Sex. But when I personally experienced the birth of paper and movable type printing from scratch, I realized how heavy the meaning of books is.

The emergence of papermaking and printing will greatly promote the popularization of education and knowledge. Not only will more people be qualified to study, but it will also change the power structure of the Tang Dynasty and make the huge ship of vassal families begin to capsize.

More importantly, this change not only affected the Tang Dynasty, China, but also the entire world. During the Sui and Tang Dynasties, woodblock printing began to appear. The Diamond Sutra became the earliest printed matter in the world with an exact date. By the Song Dynasty,

Movable type printing was invented and printing was widely promoted.

Block printing was introduced to Japan around the eighth century AD and to Egypt around the 12th century. European travelers came into contact with Chinese printing around the 13th century. Printing became popular in Europe in the 14th and 15th centuries. In Bi Sheng, movable type printing was invented.

Four hundred years later, the Germans were influenced by Chinese movable type printing technology and created movable type in European phonetic alphabet for printing books.

After papermaking and printing were spread to the world one after another, it changed the situation in which only nobles or monks could read and receive higher education. It provided an important basis for the rapid development of world science after the long dark night of the Middle Ages and the emergence of the Renaissance movement.

material conditions.

Before the invention of papermaking and printing, Korea and Japan also used bamboo slips and silk to write, India used white bark and palm leaves to write, Egypt used the inner bark of papyrus pressed into "papyrus" to write, and Europe used parchment to write on paper.

.

Whether they are made of bamboo slips, silk, or other materials, some are bulky, some are brittle, and some are very expensive. Just like the Analects of Confucius, it takes a carriage of bamboo slips to write it. And writing a Bible

, three hundred sheepskins were used. The material was not suitable for mass use, which limited the spread of knowledge.

After the spread of papermaking and printing, the above difficulties were solved, greatly promoting the popularization of culture and education, and promoting the spread and exchange of world science and culture.

After the improved papermaking and movable type printing appeared in advance, Ni Tu really didn't know how much changes it would bring to the world.

The Butterfly Effect?

"I never thought that I would change the world just for convenience!"

Not only Ni Tu was excited, but also the faces of several old craftsmen in the study.

Master Cheng's hands were almost trembling as he stroked the book, his lips were trembling, but he could not speak.

Master Luo stretched out his hand several times, and each time he was about to touch the book, he stopped suddenly. He did not dare to touch the book with his fingers, for fear of tarnishing the book.

Even if Li San'er, Li San'er's little steward, looked at it with his eyes, he would retreat to a place one meter away, for fear that the sweat all over his body would stain the book.

"This... this is worth a hundred taels of gold, but I... don't dare to touch it! If it gets dirty or broken..." Li San'er swallowed and said.

Ni Tu put down the book and laughed a few times when he saw the cautious and joyful expressions of the other three people. "Okay, no matter how precious these things are, it won't take long for them to become commonplace, just like the daily necessities we use."

."

Master Cheng became anxious when he heard this, "In that case, wouldn't the papermaking and printing techniques we worked so hard to improve become worthless!"

"Yes, we have wasted so much effort and it has become worthless?" Master Luo was also very distressed.

Ni Tu knew that the emotions in this prelude were almost brewing, so he said slowly: "If you want to keep selling at a high price, you have to make rare goods liveable."

When Li San'er heard this, he gritted his teeth and said fiercely: "I'm going to burn down the papermaking workshop and smash the stereotypes of the printing workshop!"
