Rebirth of Shuangshu

Chapter 126 Experiment
"There's another good thing for you to see."

With a wave of her hand, Lin Xiaoxiao took out a piece of jade from the warehouse.

This jade piece is an abacus made from Afghan jade.Vintage abacus in hexadecimal.This abacus was originally Lin Xiaoxiao's father's collection, and Lin Xiaoxiao played with it when she was a child.

"Abacus?" Cui Panpan's eyes lit up, "Is it jade?"

"Afghan jade is of the same texture as the jade pendant I gave to Liuniang. It is worthless in later generations, but it is comparable to Hetian jade in this era."

Lin Xiaoxiao shook the abacus, and the collision of the abacus made a clear and pleasant sound.

"It's not the point of being good or bad, the point is the abacus. With the abacus, it will be convenient for you to do business and settle accounts in the future."

"I always use linen to write calculations, and I don't know how to use an abacus."

"Huh~~~"

Lin Xiaoxiao pretended to look at Cui Panpan with contempt: "If you don't know it, you can learn it, or hand it over to the buddy, and you will be freed from the work of calculating accounts."

Cui Panpan snatched the abacus from Lin Xiaoxiao's hand, and said while rubbing it together: "If you sell this, it will probably bring you a lot of money."

Lin Xiaoxiao snatched the abacus back and put it back in the warehouse with a wave of her hand.

"Don't worry about me, but I can ask the craftsman to make you one out of wood, would you like it?"

"Yes, make a few more, and I'll sell them. A few are not enough, let's make twenty or thirty."

"If you sell abacus, you have to teach the formula to the customer, otherwise they won't be able to use it. Do you know the formula for the abacus in hexadecimal?"

"I don't know, are you?"

"I know. One up, one down, five up, four one down, fifteen down into one, two up, two down, five up, three two down, fourteen down into one"

"Great, you write down the formulas, and by the way, ask someone to write a batch of bamboo slips for me."

Cui Panpan gave Lin Xiaoxiao a batch of tasks, and then Shi Shiran went down the mountain and returned to Chongyifang.

Abacus is easy to do.

After Lin Xiaoxiao drew up the blueprints, she found Gongshugou's artisan team, showed them the finished product, and then handed it over to the artisans.For the first batch of orders, Lin Xiaoxiao asked them to make [-] first.

As for the abacus formula, Lin Xiaoxiao first engraved the formula on the bamboo slips, and then asked the children who had to learn calligraphy every day to write it.Lin Xiaoxiao then bought the bamboo slips written by the children for one cent.

By the way, ever since Lin Xiaoxiao led the villagers to settle in Laiqi Mountain, more and more scattered families from around came to seek refuge.Lin Xiaoxiao didn't care about these things, and the village committee decided to accept them after discussion.

At present, the size of Laiqishan Village has expanded to 150 people.There are more than a dozen children in the village, and they are quite a force.

In order to keep the children from making trouble in the village, besides teaching them how to read and write in class every day, Lin Xiaoxiao often assigns them some simple tasks.

For example, engraving letters.The cheap slips sold by Kunlun Study are basically carved by children.Occasionally, they are also allowed to work on construction sites to experience the hard work of their parents.

By the way, after experiencing an embarrassing illiteracy incident with Cui Panpan before, Lin Xiaoxiao realized that not everyone uses Xiaozhuan, and also realized the importance of learning several more fonts.

Although I am very much looking forward to His Majesty Shi Huang's early unification of the world and the unification of writing, His Majesty Shi Huang may not have been born at all.So Lin Xiaoxiao found calligraphy slips for self-study, and now she can understand the local characters of Rui country.

The problem of abacus and formulas is solved.The more difficult thing is the down jacket.

Lin Xiaoxiao cut a piece of linen and studied it in her hand.

Rui country's weaving technology is relatively poor. After all, the country is small and there are few people, so it is difficult to accumulate technical talents.There are no silkworm farmers in Rui State, and hemp is used for weaving.The sackcloth woven in this era is very rough.Rich people and nobles don't wear linen, they use silk and satin.

Lin Xiaoxiao took out a pile of duck feathers from the warehouse.These duck feathers have been processed and have no fishy smell. They were also temporarily placed here by Cui Panpan after they bought them.

First separate the duck feathers according to the length, and then divide them according to the thickness, and try to subdivide them as much as possible.

Wrap the duck feathers in groups of burlap, and tie the mouth with a rope.Vigorously ravage the tied sack and observe the duck feathers floating out.

The situation is so bad that there is no one who does not run outside.

This is still the case with duck feathers.It would be even worse with fluff.

No way.

Lin Xiaoxiao took the linen to find the artisan group.

In order to cope with the coming wet and cold winter, the craftsmen reinforced the house and painted tung oil on the outer wall and roof of the house.

In this era, part of tung oil was used to color lacquerware, and part was used by people in humid areas to paint houses to prevent water, moisture and mildew.It was later used on tarpaulin paper for waterproofing.Tung oil has many uses, but limited by the technological development of the times, the currently developed uses are very limited.

Paper has not yet been made.Lin Xiaoxiao thought about brushing the linen with tung oil and trying it out.

The experimental results are still unsatisfactory.The theoretical oilcloth uses cotton cloth, and the difference between linen and cotton cloth is quite large.The main reason is that the brushed linen can be waterproof, but it will still shed hair.

However, the sackcloth brushed with tung oil may have been used to make waterproof raincoats.The disadvantage is that the process of brushing tung oil is a bit cumbersome, labor-intensive and time-consuming.

No way.

Lin Xiaoxiao went to Aunt Jiang again and asked her to cook a pot of hot millet porridge.

The pot of millet porridge was filled with a lot of water and simmered on the fire for a whole night.

When I woke up the next day, the porridge was still hot, and the millet was cooked through, and it was fragrant and thick.

Lin Xiaoxiao first ate a bowl with pickles, and then took a bowl for experimentation.

Brush the sackcloth with millet pulp, the sticky millet pulp is like glue.

Lin Xiaoxiao made four samples.

The first one is to brush millet milk on a clean sackcloth, and then let it dry naturally.The second is to brush millet milk on one side of the tung oil-brushed sackcloth, and then dry it.The third is to clean the linen cloth with millet milk, and then stick the duck feathers on it.The fourth is to brush millet milk on sackcloth brushed with tung oil, and then stick duck feathers on it.

After leaving it for a period of time, Lin Xiaoxiao did various adaptability experiments with these four samples, and finally felt that the second and fourth were suitable.

And the fourth one gave Lin Xiaoxiao an illusion.Waterproof burlap with feathers gives it a faux fur feel.

Why brush millet milk on the linoleum?Because millet milk will melt when it meets water.

With the results of the experiment, Lin Xiaoxiao asked Cui Panpan to go up the mountain and told her everything about it.After Cui Panpan saw it, he felt that the second one was better.

"Why is the second type better? The fourth type directly glues the duck feathers evenly on it, which can save the filling process and ensure that the duck feathers are evenly distributed." Lin Xiaoxiao was originally more optimistic about the fourth type.

Cui Panpan rubbed his eyebrows and said: "The fourth one is too weird, I feel a little hairy. And there are too few duck feathers on it, so the effect of keeping warm is not good. The second one, you can also use the method of dividing the duck Separate the small areas of hair to avoid all falling to the bottom."

Thus, the first batch of down jackets in Kunlun grocery store began to be produced.
