Volume 1 Building the City Chapter 101 The Nitrate of Hides (1) (Proofreading)

In the three days after Zhou was scratched by the fox, Wang Tian washed his wounds with light salt water every day, once in the morning and once in the evening, and changed the dressing, which also exposed the fact that everyone's vigilance in the tribe had decreased, and they believed too much in the role of rejecting horses.

Wu is even more anxious, Zhou is the heir he finally discovered, Wu was also inspired by Wang Tian, decided to educate from the child, after the fox hurt people, Wu rarely reprimanded everyone.

Every night Wu personally checked the closure of the cave baffle, Wang Tian also prepared a night pot for these smaller children, and the leader and the second brother of King Kong even checked all the vicinity of the tribe, but they could no longer find the shadow of the little fox.

There was still no progress in the morning and evening three days of investigation, during which two brick kilns and another lime kiln had also begun to fire.

All the fish, meat, and wild boar have been marinated and stored in the pavilion with the efforts of the tribesmen, and can be hung up in two days' time.

In the past three days, the people of the hunting team have set up many rope traps around the tribe, and Wang Tian has also made corresponding trap arrangements for this fox that appeared.

In addition to not catching this little fox, these traps did not disappoint everyone, in the process of patrolling the traps every morning and evening, dozens of pheasants and hares can be harvested every day, and the food of these days is mainly based on the pigs of pickled wild boars, so the tribe has a lot of pickled chickens and pickled rabbits these days.

As the food increased, so did the need for the walls, and after a few days, the top of the gazebo was filled with salted fish and bacon.

Wu's anxiety also became more and more serious, and during the three days of handling the food, he kept wandering around the wall, and the food was not kept in a cage, which always made it difficult for him to sleep.

After the food is processed and pickled, the main labor force of the tribe is all invested in the production of bricks, and Wang Tian estimates that the red brick kiln will be burned 4~5 times more times before the materials can be prepared.

On the third day of the attack, the first batch of red bricks had been released, and the lime kiln had cooled down enough two days later.

The wall began to be built while making bricks, and Wang Tian asked Slender Toutuo to take four people to start building at the same time from both sides of the future tribal gate.

At first, because they had never done masonry work before and had no experience, they always felt that the lime mortar seemed to be out of control, and that the bricks were falling more than the paste.

In addition, Wang Tian and Slender Toutuo were strict and made slow progress, and the red bricks of the first kiln two days later increased the height of the wall by less than half a meter, but with the practice of this half-meter high wall, everyone gradually became familiar with it.

The pottery team, led by the two masters of Kuroko, led by Huzi and Xiaoli, took a group of half-grown children to start making tiles, which was made and fired at the request of Wang Tian.

The wall is built with lime mortar, it is not very waterproof, Wang Tian originally planned to bring a hat to the wall, but later considering the requirements of fire prevention, he directly decided to use tiles.

The tiles are also made using molds, and the shape is the same as that of later generations, showing a certain curvature, which is to facilitate the drainage and the coordination between the tiles.

At the same time, in order to be common to the tiles used to build houses in the future, the thickness of the tiles was made very thin, that is, one centimeter.

People in the countryside know that the tiles need two layers when they are laid, and they are buckled together through the arc, which not only solves the problem of drainage but also facilitates heat dissipation, and has good ventilation and ventilation performance.

The light and thin tiles can reduce the pressure on the load-bearing of the roof, so that the space span of the house can be wider in the future, and it is also... In order to speed up the process of making tiles and reduce the amount of use.

The width of the tiles reaches 35 centimeters and the length reaches 70 meters, so that the position of overlapping parts can be minimized, and the amount of tiles used can be reduced.

At present, the level of productivity in the tribe is limited, and the production of tiles is also a priority for waterproofing, and as for heat insulation, Wang Tian will use other ways to solve it.

Due to the improvement of the pottery process, glazed pottery has appeared, and the problem of water seepage in pottery has been solved, although the use of clay to pave the roof is faster and more convenient, but the problem of fire prevention is too poor.

Wang Tian didn't want to be attacked by someone, and the whole tribe would be burned to the ground by a torch thrown in, and the pavilion that had been built now would also be covered with tiles at that time.

In this way, even if there is a spark on the roof, it will not be able to pose a threat to the entire tribe, and the gate of the tribe and the suspension bridge on the moat, Wang Tian also let King Kong and Liu Bei start to make it.

The door frame used to install the two leaves of the gate has been erected at the position of the gate, which needs to be integrated with the fence and must be built and fixed together with the fence.

Wang Tian found that with the current speed of brick making, basically two more brick kilns can be fired every 3~4 days, and the brick making work will be completed after a week, and the wall will be fully built after two weeks.

Although this time is much later than the previously estimated time, except for the accident of the attack on the universe, the others do not seem to have delayed anything, and Wang Tian is also quite satisfied with this.

After the third day of Zhou's injury, the wound had begun to scab, which made Wu breathe a long sigh of relief, and Wang Tian also had to admire the healing ability of the primitive body.

In the later generations, such a long body wound would definitely need to be sutured with threads, and Wang Tian had planned to do so, but because there was no suitable suture, if he rashly used twine, it might be counterproductive, and he could only give up in the end.

As a result, an ugly centipede mark will be left on the arm of the universe, because without stitches, the upturned flesh will reintegrate with the skin, and it will inevitably leave an ugly scar.

Fortunately, as a boy, such scars don't have much to do with it, and primitive people don't have these particularities, and they don't have the slightest impact on the future.

These works are on the right track according to the arrangement, Wang Tian also began the nitric acid work of animal skins, and in another soaking pool, the rope grass has been changed twice, and the production of straw paper has also been carried out twice, and it is still rough straw paper.

Fish maw glue has also been made in the evening, because there is no suitable metal tool now, the mortise and tenon structure can not be tightly matched, fish maw glue is particularly important.

The nitrate of animal skins is actually very simple, the materials only need plant ash and clay (the more delicate the better), salt, lime, tools only need two knives, a blunt knife, a quick knife.

When Wang Tian was a child, he saw that the nearby villagers did this, as if it was not as complicated as in "Walking to the West".

Regardless of which of these two methods is superior or inferior, under the existing conditions, it can only be done according to the method known to Wang Tian: first use a blunt knife to shovel away the grease layer and the residual flesh on each skin, this work requires a lot of physical strength.

Wang Tian had no choice but to call the second brother of King Kong, and it was only fitting for him to do it, after removing the grease and remaining meat on the surface of the animal skin, the rest was simple.

Mix the fur side down of the hide, mix the ash salt, and a small amount of hydrated lime together, and rub it repeatedly on the leather surface.

Wooden sticks are used to beat the material to soak into the skin, then rub it again, and so on until the skin is soft, then apply a fine layer of clay.

The tanned hides are then soaked in another pond with clarified lime water and brine.

Starting from the second day after soaking, turn once a day in the morning and evening, and then need to be stirred like this for 3-4 days, if you can continue to beat, the effect is better.

During the inspection, take out a sheet, pinch a small piece of skin with your hands, squeeze out the nitrate water, if the skin is white, it is considered to be nitrated.

The next thing is to pit and dry the skin: after the leather is nitrated, a bamboo pole or wooden stick is crossed on the cylinder mouth, the leather board is hung with the dry nitrate water face up, and then stacked on the turf and a clean bamboo panel, the leather is dried on the board side up, and the head, tail and legs of the skin are flattened and straightened when drying, and the board surface is dried first and then the wool surface is dried until both sides are dried.

The sun-dried skins need to be finished, and the night before they are finished, each skin is sprayed with water until the surface of the board is moist.
