Prehistoric Survival Records

With the aid of brick molds, the speed of embryo production is very fast, which is much more efficient than Rigg imagined.

Gal and Billy made brick embryos worth nearly 100 yuan in one morning, and the yellow ones were laid out on flat ground to dry.

To prevent the side of the brick embryo from sticking to the ground, sprinkle plant ash on the bottom surface.

These brick embryos need to be completely dried before they can be fired in the kiln. Otherwise, the water content will be too high, and the water vapor will evaporate violently in the brick body, which will cause the bricks to crack. I got up the next day and it was outside the frozen world. From the beginning of winter to the present, there has not been a single rain or snow. It is spread on the ice to dry, and it is not wet at all.

After the brick embryo is settled, the next step is the brick kiln. Although they are generally kilns, the principle is similar, but the brick kiln is more complicated than the charcoal kiln. The charcoal kiln only needs to ensure the temperature in the kiln and seal it up. It is not necessary in the later stage. Reheating, the paste becomes a mud ball and smoldering is enough, while firing bricks needs to keep heating up, and the middle temperature cannot be lowered.

Fortunately, the first batch of mud bricks were fired for kiln construction, and the requirements for the aesthetics and firmness of the bricks were not high, so the method of smoldering with mud can still be used.

It would take a certain amount of time to wait for the brick embryos to dry naturally. Lige saw that there was still a large pile of clay left on the ground, and after thinking about it, he might as well not waste it and teach these orcs how to make pottery.

Rieger has no idea about how to knead beautiful decorative pottery, but if it is just practical experience such as pinching a pot or a bowl, Rieger feels that he can still handle it.

Pottery in ancient Chinese history can be traced back to the early Neolithic age. According to his observation, the civilization that Rieger traveled through was still in the late Paleolithic age. According to the normal course of history, the orcs here would transition from making stone tools to grinding them. It takes about 1000 years for stone tools and learning how to make rough pottery, but Rieger brought the two civilizations together at once, which is equivalent to unlocking the key to progress for these orcs 1000 years in advance. Its achievements are probably no less than that of Prometheus stealing fire.

Primitives made pottery at first by kneading clay into the desired shape, but this method is only suitable for making relatively small containers, such as pinching a bowl or a cup, and the kneaded pottery is often It's very rough and free-wheeling, just take the group of orcs in front of you as an example. If you give each of them a ball of mud and let them squeeze it as they like, who knows what it will look like.

In the future, the primitive people became smarter and learned to build a model first and stick clay pieces on the outside. This method finally ensured the shape. It is easy to peel off in flakes. In case of hard work to burn a large kettle, the spout falls off or the bottom of the pot falls off after a few days of use, and it will not make people depressed.

Therefore, the industrious and brave primitive people soon invented a pottery molding method, called the clay rod molding method, which is also the simplest and most practical pottery making method that Rieger thought of without the pottery wheel.

It is very simple to say, knead the clay into mud strips, coil it into a roughly desired shape from bottom to top, and then use a scraper to trim the details by scraping, wiping, pressing, and patting. Even an orc without any foundation can completely Regular and durable large pieces of pottery can be made through two or three times of practice.

There was nothing left and right, so Rigg called the Gar brothers to sit next to him and asked them to redo the clay.

Burning pottery is different from burning bricks. The gravel and grass roots in each piece of clay must be carefully removed, and then beating with stones to remove excess air and moisture in the clay. It is necessary to ensure that every lump of clay is fine and soft. of.

It is not difficult to rub the mud strips. With the hands-on ability of the two orcs, they can quickly rub the mud strips long and evenly. Rieg also described the shape of the water tank for them - flat bottom, big belly, round mouth.

Rieg first demonstrated how to roll out the bottom of a jar with mud strips, and then rolled up along the outermost circle to form a prototype of a water tank.

The two orcs obediently followed every command and every action.

With the prototype of the water tank, Rieg dipped his hands in water again, and gently applied the inside and outside of the tank, smoothing the traces and gaps of the mud stripes as much as possible with his hands, and slightly modified the edges to make them smooth and beautiful, without much effort , the mud embryo of a pot-bellied jug was formed under Rigg's little claws.

"Wow, Rigg, you are too smart, this method is much more beautiful than just kneading it with your hands!" Someone shouted in surprise.

Lige looked up, darling, what's the situation, the orcs who were idle at the side of the charcoal burning and filtering pools surrounded him at some point, and the surrounding area was impenetrable, and now all of them stretched their necks to He kept looking at the jar in his hand.

Some people stared greedily at Gal and Billy who were allowed to play in the mud together. They were too embarrassed to touch the one in Rigg's hand, but they were not so polite to the brown bear brothers. They each stretched out their paws to touch them. The mud embryo made the two of them scream while protecting the jar.

"Brown Mountain, go away, ah, ah, you have touched my pot crookedly!"

"Go away, go away, this is my jar, you are not allowed to touch it~"

Looking at this group of passionate and curious orcs, Lige thought that two sheep would be chased, and a group of sheep would be shed, so he simply distributed a ball of clay to each of them, and asked them to play with the mud obediently according to the steps he taught just now. , Rescued the two big guys who were harassed.

"What should I do? It's all broken. This is the first pitcher I've ever made." Cal looked at Rigg with tears in his eyes.

Uh... Rieg has three black lines hanging from his head, and his eyes are a bit hot.

He tried not to look at those big watery copper bell eyes, and explained: "The most amazing thing about clay is that you can shape it into any shape you want before it dries out, but I think you are I can’t save it, so I can only reset it.”

Gal is too wronged, this is his first time, and he was damaged by this group of ignorant souls, even if he squeezed it again, it is not the first time he squeezed out the jar, it is so pissed off!

The clay strip construction method is worthy of being the most widely used shaping method before the appearance of the pottery wheel, and it has experienced the wisdom of the working people.

These clumsy big guys have made their own jars after Lige taught them several times. Although the shape is still simple and rough, there are some who are too innate to make the shape crooked, at least from the surface. They are all qualified jars that can hold water.

A row of rough clay pots and mud bricks were placed to dry together, the prehistoric breeze was blowing, and the sun was basking in the sun. Rieg looked at the big, dirty but smiling men beside him. , and looked at Lige, who was jumping back and forth between the mud bricks and water jars, and suddenly felt very satisfied. This kind of emotion is probably called consummation.

After two days and one night of drying, the mud bricks and clay pots are basically dry and qualified for firing.

Lige estimated the amount of mud bricks fired at one time, first dug a large square pit on the ground about the depth of an adult orc's palm, dug three air slots, and set up three furnace bars 10 cm above the ground. It's the fuel delivery port.

Around the delivery port, put the mud bricks in a brick wall about half a person's height in accordance with the I-shaped wall-building method, and then stack the remaining mud bricks vertically inside the brick wall. Empty, fully ensure the air convection in the kiln, so that the combustion heat can take care of each brick evenly.

On the outside, use thick mud to paste all the other places except the top air outlet and the bottom feeding port.

This place is icy and snowy, and it is outdoors. Using mud to paste a layer can at least ensure that the temperature inside the kiln will not be too much affected by the outside world, otherwise the kiln temperature will not reach it, and even if it is fired, the bricks will not be strong.

After all the mud bricks were arranged to see if there was room left, Rieg picked a few round and good-looking pots from the drying pots over there and put them in and burned them together.

The latest batch of charcoal from the charcoal kiln has come out, and it is just in time to come in handy. The burning efficiency of charcoal is much higher than that of wood, but the raging flames raised by the burning of dry wood can quickly increase the temperature in the kiln, so Rieg decided to put The combination of the two is efficient and economical.

Brick embryos need to be fired at high temperature without interruption for at least 24 hours before they can be finalized. During this period, someone needs to continuously add fuel through the feeding port, which cannot be sloppy at all.

Rigg was a little worried and wanted to watch it all night by himself, but not to mention that the patriarch and his parents disagreed, even Gal and Billy didn't agree. Gal even patted his chest and promised that he would definitely watch, even if he accidentally fell asleep Besides, there is Billy, two people guarding one kiln, absolutely no problem.

Everyone was against the cub staying up late, and Rigg couldn't do anything about it. He couldn't do anything like roll around on the ground, so he had to entrust the big job of burning the kiln to his two subordinates.

Before leaving, Lige was worried about various details, such as never being stingy with firewood, charcoal must be added in time, and when adding fuel, it must be placed on the grate, and it must not be thrown into the pit under the grate for convenience. It's kind of like, I still couldn't get enough of what the two brothers said, but in the end, the parents came out and picked up the little Lige, who was only knee high, and carried him home.

On the way home, Lige was still talking, imagining that after the first batch of bricks were fired, he could build reusable brick kilns and charcoal kilns, so that he would not have to build and burn them every time, saving energy. Put a lot of effort into it.

Brick kilns can also be slightly modified and used to burn pottery. At that time, every household in the tribe can be allocated several large water containers. Stone pots that are bulky and have poor heat conductivity can even be eliminated. Well, when the time comes, you can make teppanyaki in a pan, cook soup in a soup pot, and stir-fry vegetables in a wok. When it’s cold, you can still eat hot pot around the fire with your family. It’s so wonderful.

While talking, Rigg fell asleep on Dad's shoulder, he was too tired these days.

Although he was just giving verbal instructions and watching while digging mud or moving bricks, his hard work these days has already exceeded the activity of a few-month-old orc cub. In the arms of the most familiar father, exhaustion hit overwhelmingly, so Rigg fell asleep with peace of mind after smelling the most familiar smell.

On the other side, Charlie also fell asleep on his father's neck.

Holding the most precious cub in their arms, walking with their closest lover, watching the tribe's distant flames dotted in front of them, the two fathers unanimously relaxed their steps.

In this extremely difficult world of ice and snow, they walked towards a warm home.
