I took stock of the various civilian industries in the entire jurisdiction now. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

In terms of construction, there are 3 brick kilns, 1 lime kiln, 1 cement kiln, among these things, bricks are not profitable, cement, and there is no packaging or conditions that can be transported by sea in this era.

In terms of transportation, there are various types of unicycles and two-wheelers on land, but these things are unlikely to generate much profit. There are two shipyards at sea, but their own production capacity is not enough, so how can they sell ships to the outside world.

There are a lot of details in manufacturing and industry.

Wood processing has established a series of workshops such as drying, dry distillation, lathes, etc., which can independently manufacture boards, furniture, and wood parts of various sizes and specifications after providing sufficient materials for shipyards and depots, and can also refine by-products such as wood tar, coke, and charcoal. But these things are only for personal use, and there is no big market for them elsewhere.

The Chaonan administrative region has established a set of salt drying processes and has continuously improved them, and now produces an average of 10 tons of coarse salt and 2 tons of refined salt per day.

Salt is a lucrative thing, but after thousands of years of development, it has formed its own unique circle, which can be forcibly sold with knives in the Wa Kingdom and North Korea, and these two markets are already being developed, and it will take time to operate.

But in the Ming Dynasty, the local tyrants and gentry in various places are dealing in private salt, and they are mixed in, and they will be excluded everywhere they go, and they will fight all the way, and the movement is too big.

In terms of mining, it is now possible to produce a large amount of coal, iron, clay, and limestone, but these things are available in large quantities in various places, and long-distance transportation is not cost-effective, and it is impossible to sell them in their own jurisdictions with small outputs.

Papermaking workshops, ceramic workshops, canning workshops and other workshops produce things that are either urgently needed and cannot be sold, or the quality cannot reach the level of high prices.

Chen Xin looked at the various reports, rubbed the corners of his eyes and sighed, none of them can be used for large-scale trade.

"It's better to start with luxury."

sighed with emotion, Chen Xin thought of the soap that the traverser must make, the saponification reaction is still very simple, but there was a lack of grease before, and there was no way to open a workshop if there was a lack of raw materials, but now it is better.

In the past, when planting other crops in rotation, in addition to a part of mung beans, each farm also planted some soybeans according to the plan, and after harvesting, some of them were used to squeeze edible oil, and now some can be evenly distributed and used to make soap.

Don't do any ordinary soap, in this era when ordinary people can't eat oil all year round, ordinary soap can't have any sales at all, just get that kind of high-end, various types of soap, sell as a luxury product, it should be regarded as a way to make money.

Taking out a piece of self-produced white paper, Chen Xin carefully recalled some of the knowledge points he had learned before.

The first step is to prepare a set of iron containers filled with pure water.

Quicklime is poured into the water, and it should be handled with care here, as the quicklime will release a lot of heat energy when it encounters water, which will turn the cold water hot. This step is the generation of a calcium hydroxide solution, commonly known as hydrated lime.

After that, a certain amount of soda ash is added to the water bucket where the lime has been dissolved, and this step will release more powerful heat and evaporate a part of the water. Thinking of this, Chen Xin specially marked that he should wear protective clothing when carrying out the saponification reaction.

After the reaction of hydrated lime calcium hydroxide and soda ash sodium carbonate, calcium carbonate and sodium hydroxide are formed.

All the proportions need to be carefully explored by the craftsmen, and the final result should be that after a period of reaction, the water is boiled dry, and the calcium carbonate is deposited at the bottom of the container, on which a transparent sodium hydroxide solution floats.

The next step is to carefully collect the sodium hydroxide solution, heat it and then add the grease little by little, and then continue to heat and stir, and the calcium hydroxide and the grease undergo a saponification reaction at high temperature until there is no grease in the container.

After that, it is time to purify and add various purified flavors.

Chen Xin only remembered such a little thing, and he had no impression of the specific raw material ratio at all, so he could only rely on the ingenuity of the craftsmen and continuous experiments.

This thing can't be too much, and when the specific formula comes out, it is necessary to plan the output according to the use of various raw materials, which can not affect the supply of edible oil in the jurisdiction.

After handing over what he had written to a specially established chemistry-related research institute, Chen Xin had to think about what other business-making business could be done.

At this time, it was reported that the director of the Ministry of Civil Affairs had something to see.

"Ask him to come in."

"General." The supervisor of the workshop made a gesture.

"Come and sit down."

"Yes."

The attendant brought tea.

Chen Xin spoke, always straight to the point, "Come here today, what's the matter." ”

"General, my subordinates are here to report on their work, and the second scientific research group has successfully produced a telescope, please take a look." As he spoke, he took out a brown leather case from his briefcase.

"Oh, it's finally happening."

Chen Xin took the leather case with his hand, his hand felt heavy, and after a careful look, it could be seen from the appearance of the leather case that this was a pair of standard binoculars.

Open the delicate copper buckle and a pair of binoculars with a bronze casing come into view.

"This telescope is the first practical telescope we have summed up after countless experiments, and it is made of eyepieces, prisms, and objective lenses fixed on a copper mirror body. ”

"Where's the detailed data?"

"The magnification is 10x, which means that looking at an object at 1,000 meters has the same effect as looking at an object at 100 meters with the naked eye;

The FOV value is 100/800, and the observer can observe a line-of-sight of 100 m when observing 800 m.

The radius on the inside of the eyepiece is 7 mm. ”

Then he stood there respectfully and waited.

"What else?" Chen Xin was very curious about the resolution of the most important indicator of the telescope, and when he saw that the other party no longer spoke, he asked.

The director was a little embarrassed and said, "Well, General, we have tried many times, but for the sharpness, there is still not much improvement, basically all the polished lenses are this kind of sharpness. Can you ask where you got your information? The lenses can actually improve the clarity, and there is really nothing the subordinates can do to do it. ”

Chen Xin understood that the current technical level could not achieve fine polishing of the mirror, and he did not force it, after all, it was only a military telescope of this era, and it did not need such a high definition.

"How long does it take to build such a telescope?"

"Casting the shell is very simple, as long as there is a mold, the main thing is the polishing of the lens, which requires a skilled master, and it takes about 1 month to make a pair of telescopes."

Chen Xinzhong sighed in disappointment again, but he couldn't show it yet, and said with a serious face, "It's too slow, but I also know that you tried your best, since the polishing of the lenses is so troublesome, then, for the time being, we don't need binoculars, so that the output can be doubled, and then you will issue a reward, which can improve the polishing speed of the lenses, you can improve the level of craftsmen, and issue bonuses, the specific rules are formulated by you internally." ”

"Yes, my subordinates obey."

"Also, how's the development of the marine telescope?"

"General, the principle of the ship is similar to this portable, that is, it is thicker and larger, and after the next batch of glass is polished, one can be assembled."

Chen Xin nodded, and then suddenly had a flash of inspiration and asked, "How do you make lenses?" I mean, what did the original finished glass look like? ”

"After firing, it's liquid, wait for it to condense into lumps, then take it out and start sanding. The original finished glass had no concrete shape at all. ”

"Why don't you try the mold?"

"Can a mold press glass?"

"Your thinking is a bit fixed, large pieces of metal can be cast with molds, why can't small pieces of glass be pressed with molds? Directly use the mold to make the desired shape, and then polish it carefully, is not much faster than before. ”

"That's right, as long as it's liquid, you should be able to use the mold, and your subordinates will immediately arrange for people to experiment."

"Don't worry, I have one more thing to tell you."
