Prehistoric husband and wife salted fish turn over

In fact, there are still a few steps to be done before this. Under normal circumstances, the leather peeled off from the animal must first be peeled to remove excess fat, connective tissue, and thin the skin.The people of the entire tribe at this step have already done a good job. They have been engaged in hunting or skinning for many years. Even with simple stone tools, they can handle the original leather very decently with incomparable patience and perseverance.Compared with them, Sun Zhixin couldn't do as well as them even if he had the sharp tools from the modern era in his hands.Therefore, long-term practice and experience are the most important. When they are accumulated over time, they can turn decay into magical power.

Especially with the emergence of Sun Zhixin, the tools used by the tribe have made epoch-making progress compared with the original.For example, to scrape leather, the elders of the tribe no longer use stone knives that will not be very sharp no matter how hard they are polished, but use bamboo knives pointed out by Sun Zhixin.That thing is much sharper, and you may even scratch yourself if you are not careful. The disadvantage is that you should not use too much force. Its material makes it unable to withstand strong force.

The improvement of tools has further improved the ability of the tribe to make leather. Even if the old method is used, the things produced are still much better than when Sun Zhixin did not appear.

Like these experimental products in Sun Zhixin's hands-they come from generous tribal elders. They heard that Sun Zhixin was trying to make new things, so they took out the leather in their hands without hesitation.Many of them were even disappointed because Sun Zhixin didn't choose their leather. It is undoubtedly an honor to participate in the trial production of new things by Bidaraca Asu.

Just like the children of the tribe, the thing about firing porcelain is that they squeezed the mud and used it to burn, and finally got a lot of gadgets.The little devils are generally reluctant to take it out to play, and they will only excitedly and proudly mention what they made up when talking about it, and confidently wait for the next opportunity to exchange when other tribes come to caravan.In the child's simple mind, it seems that he also has porcelain, which can be exchanged for food and contribute to his tribe and family.

The old people also think so in their hearts. They may be old, but they can still burn, providing light and heat to the tribe and their families, just like the sunset, although it is almost dusk, it is still infinitely beautiful.

Therefore, the tribal people are simple and pure and lovely.They may be backward and ignorant, but they are really generous and enthusiastic, and they have many good qualities that modern people have lost.

In line with the principle of saving and not wasting, Sun Zhixin only selected some not-so-good ones for experimentation.Just like this, the leather in Sun Zhixin's eyes looked very good.They are uniformly skinned by opening the belly line. Except for the ones that were broken during the capture and fight, the other places are very good, and generally speaking they are relatively complete.When cutting, all of them have reached the requirement of being as thin as possible without exposing hair roots.

After peeling, the leather is dried to make dry leather.When tanning, fresh fur cannot be used. It is necessary to use this kind of dry skin to soak, let it reabsorb water, and return to the appearance before it was dried before tanning.There will be a series of complex physical and chemical changes in preparation for the next step of tanning.

Soak the dry skin, and carry out the heaviest preparation step in hand.The fur obtained by the nitrification method is softer, but also has weak tensile strength and is easy to break.Among the two methods used by Sun Zhixin, he first adopted the method of alum solution, which is easier to prepare.If it works well, Sun Zhixin does not intend to try the second method.If you want to try it, you have to wait until winter passes, and we will talk about it in the spring of next year.

For this approach, its tanning formulation is unbelievably simple.Of course, this refers to applying the knowledge refined in modern times to prehistoric operations with this process. In modern times, in order to obtain better leather, the preparation of the entire tanning agent is not so simple.

Its preparation method is to count by ten, take three parts of alum, one part of salt, and six parts of water, and mix them together to form a solution.

Sun Zhixin asked Buku to grind the obtained alum ore into powder, which could not be purified. Fortunately, what was recovered at that time was natural alum ore crystals, and there were not many impurities and other compounds, which would not cause any adverse effects.The salt is purified, added water, and the tanning agent obtained after adding Mingyan is not bad.

After soaking in water for a whole day, the dry skin is almost ready, and it has returned to the shape it was just peeled off.At this time, the work of pre-watering and main watering has been completed, and the leathers look clean and tidy.

The next step is the formal tanning. Take one part of the finished tanning, use this as the stock solution, add seven parts of water to mix, soak the leather in this tanning agent and keep soaking it, and stir it from time to time.Generally speaking, this process takes three to five days to complete the series of complex physical and chemical changes.

At the same time, add a stock solution every day to gradually increase the concentration of the tanning agent.The thicker the tanning agent, the faster the softening process and the softer the tanned leather will be.There is a question of degree and quantity here. If the tanning agent is too thick, it will make the leather worse, and it cannot withstand the pulling of physical force, and you will get useless bad leather.

Sun Zhixin didn't know much about this, so he could only do it gropingly.Fortunately, he is a modern person after all, using scientific thinking and observation methods, it is very important to take notes while experimenting.

In these days, the leather should be fished out at regular intervals every day, and the oil on the surface of the fur should be removed with a scraper such as a wooden board or bamboo slices, and then put back and stirred to ensure that every part of them can be soaked evenly.Be careful when doing this, try not to get tanning agent, that stuff is corrosive and harmful to the skin.But don't be too cautious, if you get it on your body, just rinse it with plenty of water.Anyway, the camp is next to the river, and everything can be done by jumping in with a plop.

What Sun Zhixin is doing now is undoubtedly very novel to the whole tribe. Every day when he goes to remove the grease, he will attract the crowds of the tribe members.Alpha and Geben must come every day, and Geben, that restless guy, simply took over Sun Zhixin's job and brought a group of curious little ghosts to do the oil removal.

To be honest, the tanning agent gives off a weird smell when it is applied to the leather. It has a slightly pungent pungent smell, which is very unpleasant.But Geben doesn't seem to care much about this, as long as Alpha is with him, he will stir the things in the wooden basin very vigorously, giving people the feeling that a male beast is trying to show its ability and try to attract its favorite Attention to the image... Those two are male, okay?Well, Sun Zhixin admitted that he was crooked, even if he stirred a wooden basin, he could see adultery, what else could he do if he was not crooked?

That said, the whole tanning thing was pretty widespread in the camp.However, compared with the firing of porcelain, this incident was much quieter, far less grand and lively than the grand and lively scene at that time.

Many people want to ask what Sun Zhixin is doing. They can guess that he is doing a very important thing. After the thing is over, there must be something good, and it must be related to leather.But they can't imagine what it will be, because tanning leather is not like firing porcelain, and the end result is almost anything imaginable.Things like reprocessing like this were not well understood by prehistoric humans.

Usually, Sun Zhixin would explain it well. First, he himself can’t hide his words. Second, if more people understand and learn this skill, they can improve everyone’s living conditions by tanning their own leather in every household. .It's just that he's a mute now, and there are only a few people in the clan who can speak sign language, so he can't explain it even if he wants to.

Sun Zhixin didn't say anything at all, and told everyone the answer they wanted to know with facts.Anyway, these human beings are not really stupid. Once they see the results of tanning, someone will definitely learn it seriously next time I do it again, so I don't have to force them to learn.

While waiting for the tanning process, time passed slowly and quickly, and life became the same as when Sun Zhixin first came to this era, calm and leisurely.

Because he couldn't pass the barrier in his heart, and there was no progress in the matter with Naru and Tiger, the status of those two bastards in Sun Zhixin's heart was still in the position of refusing to deal with customers.I don't know if the two of them felt guilty for accidentally hurting Sun Zhixin last time or what, the two guys changed from their usual entanglement, and they have not appeared in front of Sun Zhixin recently.Sun Zhixin can only know from many traces that these two guys are the kind of stubborn people who will never give up, and they still appear around him without showing anything.

Almost every day when Sun Zhixin got up early and got out of his tent, he would see strange things on the ground outside his tent. Among them, there were small bunches of flowers—they had already bloomed and failed, and they looked like a lifeless hero. There are beautiful bird tail feathers, colorful, very gorgeous and beautiful; there are beautiful cobblestones with strange shapes and colors, which look like rain flower stones; there are other strange things, from grass roots to grass roots. Leaves, from fruits to stems, strange animal bones, terrifying insects, some stones that look like minerals, you name it.One day, Sun Zhixin also saw a ball of turpentine wrapped in a small beetle, which is the amber that is often used as exquisite handicrafts in later generations... even this thing appeared.

Since they appeared outside the tent one day, these gift-like things have never been broken.They are always placed in one pile on the left and one pile on the right, with a clear distinction, like two industrious collectors or scavengers who pick up these things every day and put them in front of their tents.

Who does the daily mess come from?If you think about it with your butt, you can tell that it must have come from two bastards, Naru and Tiger.

What does it mean for the two of them to pile up these things at the door of their tent every day?

Apologize?

Pursue?

Or try to use this to pay overnight fare?Sun Zhixin strangely felt that the possibility of the latter was extremely huge. Prehistoric humans were very pragmatic, and they would act directly when they thought about it, without those circuitous and fancy ways.

No matter what they mean, Sun Zhixin still likes them tightly.Every time Sun Zhixin sees these things, he can't help being funny and at the same time feeling warm in his heart.All kinds of signs indicate that maybe everyone is still fighting, but they always care about each other in their hearts.Sometimes Sun Zhixin couldn't help thinking that he had fallen in love many times in modern times, but he still couldn't find the feeling that love should have.On the contrary, when I saw these weird things in this prehistoric era, I felt like I was in love, which is really weird!Could it be that I have always been a hidden comrade, and I will find true love only after meeting a strong man and discovering my hidden side?

Fuck your grandma, this is too ridiculous!

Great cold...
