Duan Wenjun definitely doesn't know the details of the transformation.
However, he still has a certain understanding of the development of paper.
Papermaking, as one of the four great inventions of Chinese civilization, was a well-known thing in his previous life.
I have never eaten pork, and I have seen pigs walking.
In particular, junior high school history textbooks have detailed introductions.
Cai Lun invented papermaking, and the first thing he produced was hemp paper, which was similar to the hemp paper now produced by Duanjia Papermaking Workshop.
The hard yellow paper that is popular in Dashun today has some improvements on the original hemp paper.
Duan Wenjun no longer remembers the details of the improvement in the book, but he vaguely knows that there are some differences in raw materials and post-processing.
However, whether it is hemp paper or hard yellow paper, it is considered a relatively primitive stage in the history of paper development.
The raw materials are similar, they all use hemp or pudding.
However, these things are not very abundant in this era of the world, which naturally makes the cost of raw materials very high.
You know, most of the fabrics here are made of linen. Most people can't even wear warm clothes. How can they use a large amount of linen to make paper?
Since flax was not easy to harvest, Duan Wenjun asked Liu Yuxuan to consider using mulberry bark or cane bark instead.
Moreover, compared with hard yellow paper, mulberry paper has better toughness and smoother paper surface.
"Master, please wait for me!" Upon hearing this, Liu Yuxuan interrupted Duan Wenjun and rushed into the house.
Within a few breaths, he rushed out with a stack of hemp paper in his left hand and a pen in his right hand.
Putting the soft hair on the tip of the pen into his mouth and licking it, he quickly wrote down the four words "mulberry bark, cane bark" on the paper.
A simple and honest smile appeared on his face, "I'm a bit old, so I'm afraid I might omit something, so I'd better write it down! Young Master, please continue!"
"A good memory is not as good as a bad pen. Taking notes is a good habit." Duan Wenjun said with a smile and looked at Liu Yuxuan twice more.
This little old man was about fifty years old, and the corners of his mouth were full of ink, but he didn't care about it, which was quite interesting.
Duan Wenjun was staring at Liu Yuxuan, and Liu Yuxuan was also staring at Duan Wenjun, and his heart was even more shocked.
Mulberry bark...vine bark...
Why didn't I think of this before?
The hemp material is actually made from the hemp bark on the hemp stalks. The mulberry bark and rattan bark are indeed very similar to the hemp bark.
Most likely it will work!
The most important thing is that mulberry bark and cane bark are everywhere around Wangjiang City, and they are of little use on weekdays. If they can be used, a lot of costs can definitely be saved...
In this way, the cost of paper can be reduced by at least 30%, which means that profits can increase by 30%.
Even if the selling price of paper is reduced by 10%, we will certainly be able to seize more markets and still have an additional 20% profit...
If so, I'm afraid this paper mill can turn a profit.
In this way, I can be worthy of my mistress who died young.
Thinking of this, Liu Yuxuan's eyes turned red again, and his whole body started to tremble slightly with excitement.
However, Duan Wenjun didn't know what Liu Yuxuan was thinking. He looked at him holding the pen and staring at him, and then continued talking.
Improving raw materials is important, but our processes must also be improved in order to be competitive.
Our current paper technology all uses the method of taking layers to make paper. In this way, the roughness of the raw materials will directly determine the roughness of the paper.
Even if the wax coating technology of hard yellow paper can be used to improve this problem and make the paper surface smoother, the cost is too high.
We can consider grinding the raw materials into pulp, then cooking them, and then taking the film...
As Duan Wenjun said this, he took Liu Yuxuan's pen and linen paper and began to draw on them.
While painting, while writing, while speaking...
Although his paintings are like a group of demons dancing around, although his handwriting is like ghosts painting peach charms...
However, Liu Yuxuan listened very carefully and asked many questions from time to time.
Papermaking, Liu Yuxuan is professional.
His heart was trembling.
These things that the young master said sounded so unreasonable, but some things coincided with Mistress Qiuyun's previous ideas.
After Duan Wenjun and Liu Yuxuan talked for a while, Liu Yuxuan called several other masters from the papermaking workshop over.
Several people squatted on the ground and formed a circle. Sometimes Duan Wenjun explained, sometimes the masters asked questions, and sometimes everyone discussed together. Unknowingly, it was evening.
Butler Gu Hongfu originally wanted to tell them that it was time to eat, but was stopped by Duan Daxiong.
Although Duan Daxiong didn't understand the things they were discussing, but seeing Duan Wenjun's focused look and the excited expressions of the paper mill masters, he was sure that what Duan Wenjun said was definitely good.
Moreover, it had been a long time since he had seen the masters of the papermaking workshop with such high passion.
If I remember correctly, such a scene happened when Qiuyun founded the paper mill.
It seems like time has returned to more than ten years ago...
Just when Duan Daxiong was deep in memory of his deceased wife, Duan Wenjun stood up and said, "Old Liu, this is the theory, but how to put it into practice depends on you masters. You are the professionals. Talent.”
"My young master, Liu Yuxuan will never let you down." Liu Yuxuan nodded with tears in his eyes.
Duan Wenjun nodded, "If this method of using starch powder to cook is feasible, we can also improve the whiteness of the paper, and even make paper with different effects, such as rice paper for drawing, printing paper for writing books, Kleenex for wiping sweat, etc.”
Although Liu Yuxuan and others did not know what rice paper, printing paper, and facial tissue Duan Wenjun was talking about, they all had a belief in their hearts that by following Shaodong's method, they might be able to produce better paper than what is on the market.
That way, the mistress's unfinished wish will be fulfilled.
Seeing the excitement of Liu Yuxuan and others, Duan Wenjun patted their shoulders and said nothing more.
He did not tell them that if the research could be successful, it would probably cause an uproar among the literati of the Dashun Dynasty.
Moreover, if pulp powder can be used to make paper, it means that there are no restrictions on raw materials, and ordinary wood can also be used to make paper.
Raw materials will be available everywhere, costs will be greatly reduced, and there will be a perfect evolution of paper, which is coming soon.
"Old Liu, this matter depends entirely on you and the masters." Duan Wenjun looked at Liu Yuxuan and said, "If you have any doubts, we can discuss it together. But I still say that the details really matter. It’s up to you to just let your hands and feet go wild.”
"Old Liu, if you need anything, just tell Butler Gu." Duan Daxiong on the side also said, "Don't be afraid of spending money, just let your hands and feet go..."
"What are you doing?" Halfway through his words, he turned to look at Duan Wenjun.
He really didn't remember his son's new words for a while...
"Tink!" Duan Wenjun smiled.
"Yes, yes, tinker, tinker, tinker as hard as you can! Tinker as hard as you can!" Duan Daxiong smiled even brighter.
