The people in the workshop almost cried with joy, and they all felt that they had achieved success.
But when he saw Lin Yan slowly shaking his head, it was like a bucket of cold water pouring down his head.
Bai Chen's heart skipped a beat, "You mean you didn't succeed?"
Seeing everyone's nervousness, Lin Yan smiled and said, "Don't be nervous. These papers seem to be successful, but they still need improvement. If you observe carefully with your mental power, you will find the difference."
When Bai Chen heard this, she hurriedly took a look, and within a few minutes she discovered the problem.
"Thinner paper dries very thoroughly, while thicker paper only dries on the surface, and the moisture inside has not completely evaporated and remains."
"Good. We overlooked a problem."
Bai Chen nodded, "Different papers should take different drying times, but we forgot to consider this when drying."
"That's right. Drying time and temperature both have an impact. We need to do many more tests to determine the drying time and temperature for each type of paper."
This is a huge workload. The relationship between the number of papermaking passes and temperature and time requires the support of experimental data. Only by finding the rules can we better control the quality of papermaking.
Lin Yan didn't mention this before, because the requirements for paper are not that high, as long as the paper can be made usable. But when she got involved in person, she had a problem. Either she didn't do it, or she had to consider everything comprehensively and take all the variables into account.
Bai Chen was inspired, and Lin Yan's words helped her find the direction. The whole process seems simple, but in fact every process must be strictly controlled.
The two studied in the papermaking workshop for more than a month and found a little pattern.
In fact, the paper produced at this time is completely usable, and the pass rate has reached 60%, but they are still not satisfied and want to improve the pass rate.
It has entered the cold season. In addition to studying papermaking, Lin Yan's daily task is to teach Hong Ling and the others.
As the difficulty of the class increased, she carefully observed everyone and found that they were intoxicated, completely immersed in it, and did not appear to be stumped, so she continued speaking with confidence.
Different from basic knowledge, what I learn now is a bit more profound, which involves a lot of abstract thinking and can only be understood through imagination.
The production of yellow paper has also increased, and everyone has paper to use. Each person holds a stack of yellow paper bound with twine and writes down key points with a charcoal pen.
A thin notebook, 20 cm long and 15 cm wide, with 25 pages in total. This is a new product from the papermaking workshop and sells for 1 dime.
There are also pieces of paper sold by the piece. A piece of paper peeled off from the paper mold frame is 80 cm long and 60 cm wide, and sells for 2 cents.
Paper production has not expanded, and the limited quantity makes it so expensive. Now that the technology is stabilized, once the cold season passes, the scale will be expanded and the output will be increased, the price of paper will naturally come down.
Many people hesitate for a long time before buying one, then cut it into many small pages when they go home and are reluctant to use it.
Everyone in the laboratory has a salary, and Bai Chen is the back door, so they are so luxurious. Everyone has a small notebook.
Time passed quickly, and by the time Lin Yan was halfway through his class, it was already the end of December, the cold season was about to pass, and the new year was about to begin.
The arbitral tribunal held a general meeting at the end of the year. In addition to the original civil servants, each group selected ten representatives to attend the meeting. Summarize the major events that happened this year and make plans for the coming year.
Everyone in the laboratory participated. They asked various questions and listed the difficulties they encountered and the things that needed to be solved urgently.
It was also at this time that the participants discovered that everyone in the laboratory was thinking very differently from them.
For example, they were all confused about what the rollers, millstones, and carriages they were talking about were.
Although the people in the laboratory described it in detail, it was difficult for them to describe what it looked like without seeing it before. Just after knowing the purpose, I felt it was necessary to arrange it.
The arbitral tribunal considered everyone's opinions and approved the laboratory's funding application and agreed to expand their manpower.
It’s okay to disagree. What they raised concerns all aspects of life.
Everyone has already tacitly agreed that next year's theme will be to open up wasteland and plant wheat. Seeing that January is coming, some people have already packed up their farm tools and are waiting for the warm weather to go to the fields.
The first batch of wheat-growing families have been selected. There are thirty households in total. Each family will be allocated ten kilograms of wheat seeds. When the wheat is harvested, 10% will be kept and the rest will be handed over.
Since so much wheat needs to be grown, the mills, millstones and carriages that Lin Yan and the others mentioned are in great demand. As they say, using tools makes things much more efficient and doesn't take much longer.
Alan said: "Under the leadership of Lin Yan, everyone in the laboratory is excellent, and we must work hard in the future. The arbitration tribunal has discussed that you have made a great contribution this year and will give each of you a bonus of 1 yuan."
Lin Yan said happily: "Thank you Alan, we will definitely work hard in the future."
Who would be unhappy if you have money?
In the fifth year of the Solar Era, on January 1, thirty selected families came to Lin Yan's house to collect wheat seeds. They were all excited to be selected.
Yesterday, Lin Yan had called them together and explained the essentials of growing wheat in a day. It sounded very demanding and they had to go to the fields to take care of it every day, but they were still very happy.
This is an honor, and being among the first batch means something different.
Just imagine, in the future, every household will grow wheat by them. What an honor that is.
Nowadays, people's lives are getting better, the living standards of each family are gradually improving, and comparisons between people naturally appear.
Who wouldn't want to have a baby like Lin Yan? Unfortunately, we can only think about it. There are also those ten people in the laboratory, each one is the envy of others.
Every time Lin Yan gave out wheat seeds, he would earnestly urge them to cultivate the land carefully. Wheat is too delicate to be compared with roe and needs careful care before it can be harvested.
Every family's wheat-growing land must be reported, and Hua Xiang will conduct occasional random inspections to keep an eye on the conditions in the land.
Lin Yan also had his own little thoughts, but he didn't say them out loud. She planned to wait for the wheat seeds to be sprinkled on the ground, and she would check on them frequently and make records to lay the foundation for future planting.
This year, her plan is to keep an eye on the wheat in the fields. However, this year she does not have to work in the fields herself.
Hua Hong has gained experience, but because she is afraid that she will be too busy alone, Lin Yan's family only grows three acres of wheat.
More than half of the land that was originally circled was reclaimed, and a large area was still wasteland.
Huahong plans to plant all the land this year so that it can be planted with wheat next year.
Seven or eight days later, after a cold season when the soil thawed, Tie Er led an ox and an iron plow to plow the land of Lin Yan's family. There were about eight acres of land, all of which was plowed in one day.
Huahong came back in the evening and said with envy: "The ox and the plow are so useful. It will be great if we have a cow at home sometime."
"With the little land we have, what do we need cows for? The cows need to be fed on time and on time every day, so they are very difficult to take care of. Mom, let's just pay Tie Er and others to plow the land."
Lin Yan was not envious. The cow was easy to use and had a lot to eat. It had to be cared for by someone every day.
The order is wrong. Let’s read it this way for now. Let the editor adjust it tomorrow.
