After the embarrassing compliment, the clansman's words made Chen Jian feel a lot in his heart: he thought that the clansmen would naturally think of dyeing, but this was not the case. The man who thought of ink www.biquge.info thought that his daily work was to study ink, and what he took for granted was not the case before experiencing labor and aesthetic needs, which could be regarded as a warning: how to guide the people instead of indoctrination without a labor foundation and a demand base?

This blue-black is a water-soluble dye, easy to fade, but the cost is low, the use is large, it can be said that in Chen Jian's previous life, it is one of the two most commonly used dyes for the bottom people, and the artificial manufacture of bivalent iron catalyst is not too amazing.

It can be said that without this dye, there would be no title of Qianshou, Qian, black; The head, the head, the person wrapped in the black turban is the head of the Qian.

But the popular type of black dyeing that requires catalyst technology is definitely not as simple as the indigo dyeing that is out of blue, so why not indigo but Qianshou? Is it people's spontaneous aesthetic pursuit? Or is it the aesthetic needs shaped by the public opinion propaganda of Shang Xuan, the ruling class of the Qin State? How can the public opinion and propaganda sector function effectively in the face of low literacy rates? When public opinion is propagated, I will do what the clansmen want; Or did I just want my people to accept it?

In addition, many of the characteristics of this dye are described in many aspects of Chen Jian's classical novels in his previous life, and people's interest in the descriptive chemistry of tannic acid and alum is already well understood.

In the pearl shirt of Brother Jiang Xing, who is the first in the opening chapter, when San Qiaoer and his mother-in-law talked at night, he asked his mother-in-law how many times he had done with someone before he got married, and he could pretend to be a yellow flower virgin and marry out? The woman said that she would wash it with pomegranate peel and green alum decoction, and the bottom was tightened, and on the wedding night, she pretended to shout that it hurt and get some rouge to fool the stupid man. Pomegranate peel has always been an important source of tannic acid dyeing and coloring of the underlying tannic acid.

This story illustrates that it is not impossible to explain the world in a practical and descriptive way, and that in the unaffected natural development of civilization, this alternative science, although lacking a definition of theorems, has caused a widespread effect for the purpose of practicality, and when this practical description accumulates to a certain extent, it only takes someone to put forward a scientific method of summarizing and inductive, and it can leap from descriptive science to theoretical science - but theoretical science is not something that everyone can understand and grasp in the early stage, and it is not convenient for the spread of technology. Accumulating first and then theorizing is a road that is convenient for popularization in the early stage.

Astringency, as defined by the theory of previous life, refers to the complex feeling of wrinkling and contraction produced by epithelial cells under the immersion of tannins, alum and other solutions. In the story, it is obvious that the woman already knows that the astringency caused by the composite feeling of wrinkling and contraction will make the original greasy feeling become astringent, and the road that everyone has walked too much will become thorny and there is no road, so it is natural to be confused.

Moreover, the woman obviously knew that this mixture of tannins and alum was a water-soluble substance, otherwise the color would not be washed off after washing, and it would be difficult to pretend to be pink.

The mother-in-law does not need to know the definition of astringency, nor does she need to know that ferrous tannins are soluble in water, she only needs to know that it is useful and it will spread.

In the face of this bowl of black water, or because Chen Jian was immersed in the idea of compiling textbooks, he thought a lot, since this technology will be promoted in a few years, and with the thousands of Chinese people who have completed the enlightenment education to take root in the wilderness, how to promote it must be considered, because this will form a rule and affect the future trend.

Before the accumulation of materials is enough to popularize the compulsory education of the whole people, the dissemination of technology takes art as the main body and Tao as the auxiliary. Chen Jian stared at the bowl of black water, and warned himself to write this idea on the wooden tablet for a memo: before the technology is promoted after the ten-year plan, those people in the school must be taught a lesson in Yangchun Baixue and the Xiariba people, and in the face of the newly civilized villages and towns, when talking about technology, you must not come up and talk about why, but first talk about the technical results, otherwise you will swear that the people will not understand.

Chen Jian secretly warned himself that when compiling textbooks, he must bring into the way of thinking of this era, and after compiling it, he must first let the people of this era listen to it, and make sure that he can understand it before he can make a decision. Don't let the spring and snow fall, you must go down to the Riba people. You must not base your own way of thinking, but must conform to the way of thinking of the times.

Xu looked a little stupid and sluggish at the black and blue water station for too long, and the person who said the ink was even more worried about what he said wrong, which made Ji Xialeng feel worried for so long, but fortunately, Hongyu coughed lightly, so that Chen Jian came to his senses, looked at everyone blankly, and smiled slightly embarrassed.

Glancing at Ji Bai and more than twenty other selected guards, he said, "You will clean up all the people who are not from our clan and surround them outside. ”

After receiving the order and leaving, only the people of Xia Cheng were left here, and Jian Chen patted the bowl of black water with his hand and said: "The great river tribes worship the light and take flowers as beauty." The flowers are colorful, blue, red, blue and green, and if the color is single, you will always get tired of it. It's the same as dressing, everyone is wearing a yellow shirt, you don't want to change the color of the clothes? ”

Everyone nodded and said, "Then who doesn't want to?" As early as in the summer city, some people thought about dyeing with petal juice for beauty, but it was too difficult to extract the petals, and when the flowers were in full bloom, it was a busy time in spring and summer, so there was no time. ”

Speaking of this, everyone came to their senses, pointed to the bowl of black water and said, "This can dye cloth clothes!" ”

"yes, exactly. And it's blue-black, dirt-resistant, and you can't see it even if it's stained with dust, which saves a lot of women the strength of hammering sticks and mallets by the river. ”

After finishing speaking, Jian Chen called Ji Bai over and said, "Today, there are three things to say. One is that we can dye our clothes in the future, not only black, but also blue and yellow next year. In addition to our own clothes, we also have to exchange with the people in the rest of the cities, which can earn a lot of corn and goods every year, and can also make the money shells in our summer city become the money shells recognized by the rest of the cities. ”

"The second thing is that this matter is related to the entire city, and the more income there is, the more it is distributed to everyone every year. This dyeing method has been learned by the rest of the city, so we won't be able to change it so much. This is not the same as gunpowder, the gunpowder workshop is in Xia City, and there will be a lot of people from various cities here in the future. ”

"Thirdly, more workshops will be built in the future, in order to prevent others from knowing, I have selected Ji Bai and other twenty people, named Black Guards, to be in charge of these things. The high walls of the wooden gate can protect the people of the rest of the city, but they cannot protect our own people. So many people know about this today, I did it deliberately, so I started today, five years as a limit, if this thing is spread to outsiders, Ji Bai will find out who exposed it. After finding out, he was sent back to Xia Cheng, although there was no such rule and law, but I think that the clansmen were smashed when they heard that they could share a lot of good things, and even if they were not hanged, they would be exiled. ”

Everyone felt a chill, but they knew that this was not nonsense, and it also involved the sharing of income from the goods raised by everyone after six years.

Chen Jian took advantage of the situation and said: "Take this as an example, I will make a jade card, if Ji Bai takes my jade card to search the house and arrest people in the future, you can't stop it, I say that everyone has no objection, right?" ”

Everyone nodded, and Jian Chen grabbed Ji Bai's shoulders and pulled him over, and said, "You have to learn something from this matter at the beginning." I said that if you want to keep it secret, you need to write down all the people you heard at the time with a pen and a wooden tablet, and store it. For example, five years later, this matter was exposed, so when you check, you only need to look through the wooden tablets to find the dyed volume and ask them one by one. The old grandmother has such a good memory, and she still has to knot the rope when she is in the clan, let alone us? ”

The norms appeared little by little, Ji Bai naturally would not object, nodded yes, and according to Chen Jian's instructions, asked everyone to sign their names on the wooden tablets, leaving marks outside, and Chen Jian handed them over to Hongyu to put them together with the various things he had written down with linen silk silk in the past.

In the afternoon of the same day, Chen Jian led people to dye the change of clothes and headscarves of the people who went to find the stones, in order to prepare for the Sucheng Alliance a few days later, which can be regarded as a kind of aesthetic guidance of public opinion.

Dyeing is a set of techniques that include the removal of gum from the fibers by potassium rinsing, and how to restore the original color bleaching.

Because this is indeed the blue-black fountain pen water that Chen Jian was familiar with in his previous life, the problem is not difficult: the "magic pen" commonly used in middle school to wipe the traces of fountain pen water is mainly based on oxidants such as face alkali and sodium hypochlorite, oxidizing divalent iron or generating iron carbonate hydrolysis from blue-black to lilac-pink, so as to smear and correct the misspelled words. It can be inferred that it is also feasible to rinse this blue-black stained garment with ash potash.

After sorting out this set of techniques, it was also recorded, and the first batch of dyed clothes was ready in three or five days.

The rest of the people's clothes and headscarves were pure blue and black, and Ji Bai and the others added some gum and pine ink to the dye, and after melting it with beeswax, they drew the wheat ear logo of Xia Cheng on their bodies.

The wax logo of the wheat ear can prevent the dye from being applied to the wax melt when dyeing, and the wheat ear left behind has a natural streak left by the wax being rubbed, which is very layered and tasteful, which is very magical, which is marketed to the noble class of each city.

Everyone was wearing dyed new clothes, excited, a few days later, the people who went outside to look for stones also came back one after another, the harvest was gratifying, but there was no result that Chen Jian wanted, fortunately, there were still more than a dozen people who did not come back, and there was still hope.

While waiting for everyone to return to the team, Chen Jian selected 200 printers and dyers, and took out the records of what these people had done when they were slaves, and selected 4,000 strong people as workshop workers, and the remaining 4,000 were taken to the jungle on the other side of the lake, with 800 people as a team, divided into eight village farms, and told them to set fire to the mountains first and prepare for autumn planting.

Let Redfish select sixteen of the people in Yucheng and let them be stationed in the villages and farms where there is nothing to guide farming.

When the agreed day came, there were still more than ten soldiers sent out who did not come back, and Jian Chen also knew that this era was likely to delay the date due to some accidental factors, so he didn't wait any longer, and just said that he would let them go to Sucheng by himself after they came back.

However, before leaving, Hongyu, who had just finished distributing things from the village farm, ran to the dock out of breath and pulled Chen Jian aside, looking anxious. (To be continued.) )
