Although ancient pencils made of graphite have appeared in China for a long time, until the Qing Dynasty, ancient pencils were simple. They just used small wooden boards to clamp the pencil lead made of graphite, just like the pencils used by Jia Yun in his previous life, but regardless of their appearance
The ease of use is quite different.
Jia Yun found it inconvenient to write "The Eight Parts of the Dragon" with ancient pencils at first, but she got used to it after using it for a long time.
In his previous life, Jia Yun was a science and engineering student who graduated from a key university. He also worked in military industry research and development for many years, so his research and development capabilities are naturally very strong. He has also read in books how to make pencils, colored pencils, pencil planers, and erasers. With his
With a strong memory, he can now remember these methods.
The level of ancient craftsmen in this world is actually not low. After all, they can even make firearms.
Jia Yun asked Cheng Huanian to find several powerful craftsmen as his assistants, and developed modern versions of pencils, colored pencils, and pencil sharpeners.
In fact, the research and development of these three things is not difficult.
Graphite and clay are prepared into a mixture according to a certain proportion. Although there is no core press, Jia Yun asked craftsmen to make molds to extrude the graphite clay mixture, then heat, dry, and roast at high temperatures, and finally oil immersion treatment to create a modern version.
of pencil lead.
The manufacturing method of colored pencil lead is similar. It does not require graphite or high-temperature roasting. Clay, talcum powder, adhesive, colorants, grease, wax, etc. are mixed evenly, then shaped and dried.
The focus of pencil board manufacturing is to cut the logs into wooden blocks, heat, dry and high-temperature treatment, so that the pencil boards produced can be softened and easily sharpened.
The processing of pencils is to dig out a groove for the pencil lead in the middle of the two pencil boards, then put the pencil lead in and glue the two pencil boards together.
The pencil sharpener is easier to make. The only difficulty is to install a blade at an angle.
…
…
Jia Yun herself has to be busy with martial arts exams and continues to write novels. Her future goal is to rise quickly in the officialdom...
For him, producing and selling pencils, colored pencils, and pencil sharpeners is just a small thing, and he doesn't spend a lot of time and energy on it.
So Jia Yun handed over this matter to Cheng Huanian, and also handed over the core technology of manufacturing pencils, colored pencils and pencil sharpeners to Cheng Huanian.
Jia Yun already has great trust in Cheng Huanian, and the two have been friends for many years. Moreover, Jia Yun's status is now extraordinary, and Cheng Huanian will not cheat him.
In fact, the technology is simple and does not have much technological content. Once pencils, colored pencils, and pencil sharpeners become popular, other businessmen will find craftsmen to develop them, and it will not take long to develop them.
Now, under the leadership of Cheng Huanian, the first batch of pencils, colored pencils, and pencil sharpeners have been manufactured, and the quality of the products is very good.
Jia Yun said to Cheng Huanian: "In addition to pencils, colored pencils, and pencil sharpeners, I have also recently developed a method for developing pencil erasers."
Cheng Huanian wondered: "Pencil eraser?"
Jia Yun smiled and said: "Pencil eraser is a lump that can erase the handwriting written by pencil."
After listening to this, Cheng Huanian pondered for a while and realized the importance of the eraser. Once this kind of thing is developed, the pencil will be more convenient to use and easier to sell!
Cheng Huanian asked in surprise: "Is there such a thing?"
Jia Yun immediately explained...
For this era, let alone China, even in the West, the eraser has not yet been born!
In previous lives, the fact that an eraser could erase pencil writing was only discovered by Western scientists in 1770. Before that, Westerners used bread to erase pencil writing. After it was discovered that the eraser could erase pencil writing, it caused a stir
It was a big sensation because it brought a lot of convenience.
China only began to introduce rubber in 1904.
Now that there is no rubber, Jia Yun naturally cannot develop an eraser. He can only develop a simple version, which he currently calls a "pencil eraser."
Pencil erasers are also very simple to make, using glue, starch, baking soda, colorants, etc.
After listening to this, Cheng Huanian was still surprised: "Is it really possible?"
Jia Yun smiled and said: "Sir, if you are not busy today, you can stay here and watch my research and development."
Cheng Huanian nodded immediately: "Okay."
This is an important matter to him. If Jia Yun can really develop a pencil eraser, it may mean a huge profit!
Immediately, Jia Yun developed a pencil eraser in the factory, and several craftsmen became his assistants. Cheng Huanian was always watching.
It only took less than three hours. By the afternoon, Jia Yun had produced more than a dozen pencil erasers with good results, which amazed Cheng Huanian and several craftsmen.
Cheng Huanian said: "With this pencil eraser, our pencils, colored pencils, and pencil sharpeners will be more likely to sell well, and the pencil eraser itself may also bring a lot of profits."
Jia Yun nodded: "Sir, this will be a big deal. You and I have only invested a total of two hundred taels of silver before, which is too little. I think it would be better for you and me to invest another five hundred taels of silver each now."
According to previous discussions between Jia Yun and Cheng Huanian, Jia Yun was responsible for research and development and investment of one hundred taels in the business of pencils, colored pencils, and pencil sharpeners (and now an additional pencil eraser), while Cheng Huanian was responsible for production, sales, and investment of one hundred taels.
The two of them split the profit 50% each.
In other words, Jia Yun has invested one hundred taels, which was the reward he received when he first visited the old lady of the Cao Mansion, Mrs. Cao Wei.
Now that Jia Yun wants to invest an additional 500 taels, Cheng Huanian also needs to invest an additional 500 taels.
Well, the main reason is that Jia Yun didn't have a lot of money before, otherwise he would have invested hundreds of taels before!
Cheng Huanian was surprised: "Each person invests another five hundred taels? A total of one thousand two hundred taels? Brother, is this too much?"
Although he was a wealthy businessman, he felt that pencils, colored pencils, pencil sharpeners, and pencil erasers were likely to sell well, but he felt that investing one thousand, two hundred taels in this business was still too much.
Jia Yun said calmly and calmly: "I told you before that pencils, colored pencils, and pencil sharpeners are easy to sell. Once they sell well, you can make a lot of money. As for why they are so popular, I have also explained to you in detail. Now there is another
Pencil erasers will be easier to sell and make a lot of money."
"When we discussed before, we only said that these products would be sold in one Qiwenwu flagship store and eight chain stores. I think this is not enough and is too inefficient."
"We invested another thousand taels together and bought an old courtyard house in this alley and converted it into a factory. Now the factory is smaller. We will recruit more craftsmen to increase the production of these products. In addition to Qiwen,
It is sold in bookstores and wholesaled to other related stores."
"In this way, we can make these products sell well as soon as possible and make our business bigger and stronger as soon as possible. Well, we can make the scale of this business very large and make the profit huge!"
Cheng Huanian: "..."
After a brief hesitation, Cheng Huanian nodded and said: "Since I am so confident in this deal, I will comply with your wishes and invest another five hundred taels!"
Although Cheng Huanian is much older than Jia Yun, Cheng Huanian admires Jia Yun in his heart because Jia Yun is really a genius and a multi-faceted genius.
Cheng Huanian believed that since Jia Yun was so confident in this deal, the deal should be successful. Even if he lost money, it would not matter. He did not miss the money.
What's more, the money "Tian Long Ba Bu" can earn him will be far more than 500 taels of silver.
What's more, Cheng Huanian now not only respects but also thinks highly of Jia Yun. Even if he wants to please Jia Yun, he doesn't mind spending an extra five hundred taels of silver to accompany Jia Yun to take a risk.
