Chapter 350: Papering the windows? (Please vote and subscribe)
In the third month of summer, the reconnaissance and mapping team led by You Ye was getting closer and closer to the cannibal's territory. At the same time, the two people separated from their team had already reached the highland grassland, successfully contacted the hunting tribe alliance there, and persuaded them to join the expedition team heading south to visit the Han tribe.
In the south of the Han tribe, the large-scale caravan led by You Fu was also on the way to the grassland south, and from time to time they encountered some labor teams heading in the opposite direction; further southwest, the caravan of the Xin tribe was also heading towards the grassland under the leadership of the merchant elder.
In fact, whether it was from the Han tribe to the grassland or from Zhudao to the grassland, it would take more than a month to walk, so the two teams set out almost at the same time, and there was a great chance that they would meet, not to mention that both sides were interested in finding each other, so it was only a matter of time for them to meet in the grassland.
However, Luo Chong was not too worried about this matter. He had already equipped them with the most elite cavalry, and all of them were equipped with standard long swords. Even if they encountered trouble, even if they could not fight, they would definitely be able to fight their way back.
So Luo Chong was very confident in them, and his mind was not always on this. The Han tribe still had to develop, and there were still many things to do, so he still couldn't sit still.
In June, the rice cultivation in the new city area had ended, and there would be at least one season of output this year, which made everyone feel very relieved, meaning that they could live well this winter, at least they would not starve. The food problem was solved, and then the next thing was to store houses and firewood for the winter.
Fortunately, there were many people in the new city area, two or three thousand more than in Hanyang City, not including those foreign laborers. If they were included, the number would be even greater. With so many people coming to build, Luo Chong was still confident that enough houses could be built before winter.
The construction of the new city area was in full swing, and the construction progress in Hanyang City was not slow either. The tribesmen were taking slaves to do the final capping work on the newly built teaching building.
The construction speed of the teaching building is still very fast. Although it is a building, there are only six classrooms on the first floor. In addition to the corridors and stairs, there are only six large empty rooms. In fact, the amount of work is not large, and the large amount of wood needed has also doubled in efficiency due to the wind power wood processing plant, so there is no problem in supplying the construction needs.
After the foundation was laid, the walls were all built with blue bricks. The corridor is a north-south corridor, which is convenient for lighting inside. Each classroom has three large windows on the side close to the outer wall of the teaching building. The classroom is close to the inner side of the corridor, with a door in front and back, and a row of very high flat windows on the inner wall near the corridor. The fear is that the corridor is too narrow and long and affects the lighting inside the building.
After all, there is no electric light now, that is, there is an oil lamp, but it is best not to bring the oil lamp into the teaching building. There is wood here, and it will be troublesome if it is lit.
The teaching building is a rectangular tube building. The classrooms are arranged vertically, three on each side, with a corridor in the middle and a staircase at each end. This kind of building is very symmetrical, stable and strong.
After each layer of wall is built, a thick wooden floor is added. The strength and load-bearing capacity are absolutely no problem, but the maintenance of wood is very problematic. Wood is afraid of moisture, but waxing is too luxurious. Paint will also wear out after a long time. In addition, so many people step on it every day, which can easily wear off the paint.
Moreover, these wooden floors are not waterproofed like the deck of warships, which results in gaps between each wooden square. It can be said that it is neither waterproof nor soil-proof. If it is really used directly, it is very likely that some water will be spilled upstairs, and it will rain downstairs. If there is a lot of dirt on the soles of the children upstairs, it may leak dust downstairs. So Luo Chong asked people to install ceramic floors on the wooden floors.
Ceramic floor is not much different from modern porcelain tile. It is made by rolling clay into mud cakes, cutting them into squares, drying them, applying glaze, and firing them in kilns. Finally, the finished product is available. This thing is actually not much different from making tableware. You can also directly use it as a large porcelain plate. Well, the difference is in size and shape.
The glaze color used for porcelain tile is light gray, which is made by mixing iron ore powder and other stone powders. This color is more resistant to dirt than white, but the color is not very dark, which can ensure bright indoor light.
After the porcelain tile is made, you should first brush a layer of tung oil on the wooden floor, then moisturize it several times, and then spread a layer of mud mixed with straw on it, and then lay the floor. Finally, the floor is laid with tiles, and the floor below, that is, the ceiling of the next floor, is painted white, which is convenient for improving indoor lighting.
Speaking of lighting, we have to talk about windows.
Thanks to the sudden increase in animal skins last year, the windows currently used by the Han tribe are actually the same as before, with a lattice frame made of wooden strips and then covered with animal skins. This kind of window is not ventilated, not breathable, and not transparent. It is fine for winter, but it is summer now.
This kind of hot and stuffy window has long been replaced by the tribesmen themselves. Some directly remove the animal skins and leave only bare wooden lattices on it, while others hang a layer of translucent straw mats on it.
However, these are not long-term solutions, and it is even more impossible to put them in the teaching building. Luo Chong’s most ideal raw material for making windows is actually paper.
Using paper to paste windows has been around since ancient times and is no longer a secret. Although white paper is not strong and afraid of rain, you can brush tung oil on it, just like making oil-paper umbrellas. After brushing the oil, the light transmittance of the paper will increase. Some people may have seen that after dripping oil on white paper, it will become translucent and not afraid of water. This is exactly the reason.
In addition, if you feel that white paper is not strong enough, you can make it a little thicker when making paper. This is flexible. No one stipulates how thick the paper must be. What quality of paper is needed depends entirely on your own needs.
Making paper to paste windows is a new goal set by Luo Chong. It is not only to solve the lighting and waterproofing problems of the windows, but also because the school has been built. It is impossible not to invent paper and pen. What about students going to school and how to study? These are all problems.
Now there is nothing else for Luo Chong to manage, so he can use this free time to make paper. Well, toilet paper is also a problem. He doesn't want to use clods of earth and leaves to wipe his butt anymore.
