Prehistoric husband and wife salted fish turn over

Watching a group of hunters drive out of the camp vigorously, Sun Zhixin returned to the tent to study the pottery firing.

Well, in fact, when he watched the hunters leave just now, he was not in a good mood. The whole hunting activity was really dangerous. He was worried about Naru, Tiger, Ogg, and even the familiar Master Kong. A man's wife on the battlefield.

This made Sun Zhixin very depressed, and even looked down on himself, which made Sun Zhixin lose his usual refreshment.But just because I like these people in my heart, I can't see them getting hurt in any way.At the same time, I also understand that in this prehistoric era with low productivity, and under the current situation where planting and breeding have not developed, the main way to obtain food can only be obtained by hunting with dangerous physical means.So on the one hand, I have to do it, and on the other hand, I have to worry about it, which makes people very contradictory.

Putting aside these negative emotions of being powerless, instead of worrying about adding troubles, it is better to work harder to discover and find, and innovate new things to improve the life of the tribe, and protect the people close to you with your own weak power.

Sun Zhixin went back to the tent, set up the ostentatious solar charging board, and connected it to a PDA to study how to fire pottery.

Sun Zhixin is well aware of the entire process of firing pottery, and generally speaking, it can be divided into four steps: mud mixing, molding, glaze mixing, and calcination.The step of mud mixing can be skipped because of the discovery of high-quality clay. Of course, it is not known whether the clay is good or not until it is actually burned.

According to the data, in the early stage of pottery development, human beings often took soil randomly, used the step of mixing mud to remove impurities in the soil, and then added other soil or mixtures according to the soft plasticity of the obtained soil in order to obtain a reasonable soft and hard speed. .They are different from Sun Zhixin, they are groping everything from scratch, while Sun Zhixin starts to grope and practice on his own based on the written materials accumulated by countless experiences. Compared with the difficulty level, what Sun Zhixin does is undoubtedly simple pole.

For example, for the materials used for firing pottery, he skipped the thousands of years of discovering materials, researching materials, and summarizing high-quality materials, and directly selected the most plastic and burnable clay.This thing is soft but bad, it is called a knife when it is dry, and it is the best material for making pottery.

Then there is forming, which is more sophisticated, and truly excellent forming is not a one-day effort, and it cannot be achieved casually.Fortunately, Sun Zhixin only intends to burn pottery used in daily life, not any artistic treasures.It shouldn't be too difficult to pinch a pottery bowl, or rub a straight bottle, right?Even if the big ones are difficult, can we burn the small ones first?Wait for the technique to improve before burning others.

Skip the glaze directly. Generally speaking, this step in the early stage of firing pottery is to make the fired pottery hard and have better water resistance. At the same time, it can also make the pottery embryo not easy This step is only carried out if there is cracking or damage.Theoretically speaking, pottery embryos that have undergone the glazing process are easier to fire, and the surface of the fired finished product will have a glaze structure with a glass luster, which will be better in terms of impermeability and aesthetics.But the firing temperature of the glaze is very high. It was difficult to make the fuel reach such a high temperature when exploring pottery firing from the beginning, so I chose to give up.

Of course, this is based on the selection of high-quality clay as the material for firing. Otherwise, glaze should be considered to strengthen the surface strength and prevent cracking during firing.

The last step is calcination, which is the most important step. Success or failure almost depends on it.

There are two key points to determine the success of this step, one is the fuel for firing pottery, and the other is the reasonable construction of pottery kiln.Generally speaking, the temperature for firing pottery is around 800 to 1200 degrees. If this temperature is not reached, the clay will only dry and harden further, and it will not allow it to produce a series of complex physical and chemical changes, and finally form a real clay. pottery.

In the early days of pottery firing in the historical era, people piled firewood directly on the flat ground, similar to firewood, wood, etc., placed the kneaded pottery embryos on these fuels and piled them directly for burning, and finally obtained pottery. Due to the low temperature and scattered firepower during the firing process, the tools appear to be of poor quality, cannot withstand use, and the yield is extremely low.

Later, in the Stone Age of the new era, humans have developed two common types of pottery kilns for firing pottery, the horizontal pit kiln and the vertical pit pottery kiln, which greatly improved the success rate and quality of pottery firing. Mass-produced pottery that can be used in real life.

The kiln that Sun Zhixin intends to build is one of these two, or to build one of both to try.Because his concept of them is very vague, many things can only be known by really trying them.Fortunately, the structure and construction of these two kinds of pottery kilns are very simple, and it will not take much time to instruct Tarim, a strong man, to do it.

Comparing the two kinds of kilns, the horizontal cave kiln is more typical. Whether it is a horizontal cave or a solid cave, there are common parts, which are composed of a burner, a fire chamber, a fire channel, a kiln chamber and a kiln grate.The outermost is the burner, which is used as an opening for putting in fuel; along the inside is the fire chamber, which is the main combustion chamber; the flame and heat generated by the combustion of fuel pass through the fire channel and kiln grate, and finally reach the kiln chamber , The pottery embryos are all placed there waiting to be fired into pottery.

The flame route when firing pottery is the fire chamber-fire path-kiln grate-kiln chamber.The kiln chamber is circular, with a kiln grate on the bottom and many fire holes on the grate. The flame entering from the fire chamber reaches the kiln chamber through the fire channel and fire holes.The kiln chamber of the vertical cave kiln is above the fire chamber, while the horizontal cave kiln is connected horizontally with the fire chamber. Theoretically speaking, the structure of the horizontal cave kiln is simpler.

However, their so-called simplicity also made Sun Zhixin spend a lot of time studying it. After he had a general idea of ​​everything in his mind, he decided to excavate the clay, rub the mud to make embryos, and dig and build while waiting for them to dry. A horizontal pit pottery kiln.The more complicated shaft kiln will be discussed after Tarim returns.

Sun Zhixin is very straightforward in his work, and if he decides to do something, he quickly recruits people.The women in the clan don't plan to move, they are still spinning flax now, and that job takes a lot of time to finish spinning the collected flax when the tools are outdated.At the same time, this is a tedious and boring job, which is very tiring and hurts the eyes after a long time.

The women in the clan are very industrious and hardworking. After many women know that this thing is a good thing, when their men and children are asleep at night, they continue to spin there by the dim light from the fire.Prehistoric women would go to such lengths to give their families a better life!From this, Sun Zhixin respected and cared for them from the bottom of his heart, and couldn't bear to increase the workload for them.He knew in his heart that as long as he said something, these great women would definitely respond without hesitation, but he really couldn't bear it.

Then, there are only those little ghosts and teenagers left. Apart from the necessary work of collecting firewood, they still have a lot of time to play. If you don't order them, who will you order?Besides, the little ghosts and the teenagers are all quick on their feet. Although they can't carry a lot of weight like adults, it's no problem for each of them to carry five catties and ten catties of clay.

The road to collect clay was taken by Sun Zhixin during a picnic with Buku. It was an easy and safe way to go. Let the young ghosts go in groups. With their active temperament, the back and forth will be very fast, and it will definitely be possible. Get the material back quickly.Another group of teenagers can also play together when they go out in groups. They can hunt whatever they want with a blowgun, which can be regarded as taking care of work and play.

After thinking about it, he asked Buku to gather the teenagers in the clan, thinking that they were all underage, and most of them were hungry for delicious food, so he made a lot of pear juice to entertain these little guys.

Buku rushed out like a little black dog to call for someone, and after a while, a group of young men came up to guard outside Sun Zhixin's tent.Just as Sun Zhixin first counted, there are a total of fourteen boys and girls, led by Buku, Lu Gaoyin and Berna, nine boys and five girls.

Everyone was naked, especially the girls, whose bodies had begun to develop, and small bags were exposed on their chests, which made Sun Zhixin embarrassed to look away.He didn't want to be a wretched uncle in front of these really pure little devils.

Nima!In the future, he must find a way to make them wear something earlier, so that they won't be embarrassed to stand in front of him, but he just can't bear the appearance of everyone walking around naked.

A total of fourteen teenagers and children all looked at him with bright eyes, which made Sun Zhixin feel ashamed and ashamed at the same time.The children in the clan admired him, Bida Acha Asu, besides Naru, he seemed to be the second most powerful person, and his status in the hearts of all the little devils was even higher than that of the wise Auric .Although Student Sun has various flaws, he has a very good conscience, and he feels a little guilty when he is looked at by such pure eyes.

"Cough cough!" Coughed twice in a false manner, Sun Zhixin said: "Call everyone to help with something, there is a thing called clay, after a while Buku, Lu Gaoyin and Berna will take everyone to recognize it. It, pick some more, is there a problem?"

Everyone shook their heads, there was no expression of reluctance on their faces, but they were all eager to try.Bidaraca Asu's order is a kind of honor to them, and these little guys are so simple.

The order was conveyed without any hindrance and was well executed. A group of people, led by the three of Buku, turned around and was about to act.Seeing everyone's efforts, Sun Zhixin felt embarrassed, and shouted: "Hey, hey, wait a minute, I have something delicious here, everyone, take it with you on the way."

It's still a bamboo tube, which has been widely used recently.But there is not one for each person, there are only six, and the three of Buku must be counted.The three of them are very close to Sun Zhixin, and they always come first if there is any benefit.

Among them was a little girl who looked like she was about ten years old. She took a sip from Buku's bamboo tube and immediately opened her toothless mouth, her eyes bent into two crescent moons, and said happily: "Sweet! Really! delicious!"

That appearance is really cute, just like Buku, he is also black and thin, he looks like he is malnourished, his small face is only the size of a palm, so his eyes look bigger and greener in color.Sun Zhixin thought for a while, gave her his bamboo tube, and asked with a smile, "What's your name?"

"My name is Ya." The little girl took the bamboo tube fondly, without being polite at all.She has wanted this for a long time, but she has to take care of the hunter and other brothers in the clan first, so she has been holding back from wanting it, and now she just got one.

Sun Zhixin is happy, her name is also monosyllabic like Kang.Sun Zhixin smiled and called her with two syllables: "Yaya, pay attention to safety on the road, and uncle will make this for you when you come back."

"Okay!" Ya was even happier, and ran away with the other children, her withered and yellow hair was tied randomly behind her head, dancing with the wind, which made people feel pity and uncontrollably want to love her.
