survival in the wilderness

Chapter 115 Paper Copying
Since he couldn't find the reason for the breakthrough, Lin Yan didn't worry about it any more, as long as the result was good.

Feeling excited, Lin Yan didn't feel sleepy for a while, so he found a book and started reading.

I don't know when I fell asleep just looking at it.

When I woke up again, it was daylight.Lin Yan hesitated for a while, then suddenly realized that today is September [-]th, less than a month before the cold season.

There are a lot of things to prepare at home, I don't know if A Niang has started to make them.

A Gulu got up and looked around the house.

Due to land reclamation one after another, the dried haystacks are piled high, and there is also a lot of firewood, which should be enough.

There were already fifty or sixty pikas in the pen, and the pen was crowded to the brim. Lin Yan felt that the pen was a bit small, and it was not good to be so crowded.The pikas were all listless, unable to use their skills.

Nowadays, charcoal is a must-have item in the cold season in Sun City, which is very cheap, and you can buy six catties for one penny, but the bonus is that you don’t want to spend this money, so you usually just pick up firewood.

Lin Yan thought, when he was free, he went to buy some charcoal for preparation.Anyway, her salary is enough, as long as she doesn't buy clothes, she feels that she is quite rich.

In the kitchen, there were four large bags of chestnuts, three cans of sesame oil, and various dried fruits and meat.

After checking it again, Lin Yan felt that Huahong had always had the habit of storing food in his bones, preparing it all the time, for fear that there would be nothing to eat.

In fact, many people have this habit.They used to be afraid of starvation and cold. Although the conditions are much better now, they still cannot change their old habits.

Hua Hong took care of the house very well, Lin Yan felt that he was just worrying.Just do your own thing.

When we arrived at the papermaking workshop, Bai Chen had already arrived, leading a few people to move the vat.

Seeing Lin Yan, she excitedly said, "Why are you here?"

Before Lin Yan could speak, Bai Chen dragged her to the big vat, "This is the latest slurry. It has been washed and added with chestnut powder. I'm going to filter it again before making paper."

Lin Yan looked at the yellow-brown slurry in the tank, with some impurities floating on it, she said, "Do as you want, I'll take a look first."

In fact, Bai Chen is very clear about the papermaking process, and strictly controls every link, but the result is not satisfactory.

Lin Yan just came to see what went wrong, and helped to improve it, so that the quality of each batch of yellow paper produced was consistent.

Now it is only a small-scale trial production, and the process cannot be stabilized. If the scale is expanded, it will be a disaster.

The whole process of papermaking is time-consuming and manpower is required. If qualified finished products cannot be produced, it will be a huge waste.

With Lin Yan around, Bai Chen's confidence greatly increased, and he continued to do the next work in an orderly manner.

The slurry is filtered by using several layers of burlap as a filter cloth. After filtering out all the impurities visible to the naked eye, the slurry looks much cleaner.

Lin Yan made the paper himself, and picked up the paper frame in the pulp, so that the pulp remained evenly on the paper frame.

She looked at the paper-making frame, and there was very little pulp left.

"What's the matter, is there a problem with the paper-making mold frame?" Bai Chen asked nervously.

Lin Yan said: "The paper-making mold frame is not fine enough, and there is very little pulp left, so we have to find a way to change it. Did you only make paper once before?"

The current papermaking mold frame is woven with fine and dense cattail grass, which has good toughness and is resistant to water immersion.It looks flat and there are no gaps, but it can pass through the slurry once, but it can't hold the slurry.

Bai Chen nodded, "Yeah, make paper again, I've been trying to change the slurry."

She quickly realized, "You mean, if you copy it several times, the amount of pulp residue will be different, and the paper you will make will be different?"

"Yes. There is no difference between one pass and two passes, but there must be a difference between one pass and five passes. Just take this batch as an experiment, and copy it once, twice, and twenty times. Let's compare the difference between the papers. "

Bai Chen and Lin Yan worked together and made ten sheets of each kind.Mark it well, dry it slightly and put it in the baking room.

The temperature of the baking room is controlled at about [-] degrees to ensure that the water evaporates at the same speed, and the paper made is smoother.

After a busy day, the two were exhausted.

Lin Yan sighed: "It's more tiring than working in the fields."

"I'm used to it, but I don't think so when I do it every day." Bai Chen's eyes sparkled, "After two days of baking, the paper will be peeled off. I have a hunch that it will succeed this time. As soon as you came, you found a loophole. Why didn't you think of this?"

"Wait until the results come out. Sometimes it feels inaccurate. The pulp you made this time is very good, delicate, and the consistency is well controlled."

For the next two days, Lin Yan and Bai Chen plunged into the paper-making workshop, constantly observing the changes in the paper in the baking room.

It is recorded every half an hour, and the entire drying process is recorded in great detail.

When the drying was completed, everyone stared wide-eyed at the flat paper on the paper-making frame.

"This looks like good paper, each sheet is very flat, without wrinkles."

"That's right, it's better than every time I watched it before."

Bai Chen restrained the excitement in his heart, "It won't be considered finished until the paper is peeled off."

Lin Yan touched it with his hands, and it felt slightly rough, but it was much better than the previous yellow paper.

She activated her mental power and carefully began to peel off the paper.

When a complete piece of paper was peeled off, everyone cheered immediately.

Everyone felt that Lin Yan made the paper perfectly. The flat paper looked like it was in the paper mold frame, without any wrinkles.

Not everyone can do this job.

Bai Chen couldn't do this by herself, she had done it many times, but still couldn't achieve Lin Yan's effect.

The paper in Lin Yan's hand was made in one pass. It is very thin, and it has good light transmission when viewed against the sun.

"Lin Yan, take off one of each of the remaining samples, and we will use them for comparison." Bai Chen urged, her heart beating faster.

This time, the paper that was copied once was successful, so the remaining samples should also be successful. Let Lin Yan do it, and the paper that was peeled off will look different.The contrast will be clearer and the results will be more accurate.

Lin Yan nodded, and carefully peeled off one sheet of each sample, a total of twenty sheets of paper.Her hands are steady without any mistakes.

The people who usually peeled off the paper in the workshop were greatly shocked when they saw the paper that Lin Yan had peeled off.They have done it themselves, so they understand the difficulty better.How on earth did she do it, there is no flaw at all.

Twenty sheets of paper were spread out on the table, and at first glance, they were almost identical.

But if you look closely, the difference is huge.

From No. 20 to No. [-], it corresponds to the number of times of papermaking, and the thickness of the paper changes gradually.From thin to thick, as long as you touch it, you can immediately feel the difference.

Bai Chen touched them one by one, and he was sure in his heart that Lin Yan was right.The number of times of papermaking is very important. If you want to make thick paper, the more times you need, the better.

She said: "This time it was a big success, thanks to you, we will have paper soon."

The other people in the workshop were also excited. They had worked hard for more than half a year, but with little success. Many people felt more and more hopeless.

But today, they are full of confidence.
