Glassmakers in the Venetian era used the reaction of mercury and tin foil to make glass. It's very simple to say, spread tinfoil on one side of the glass, pour mercury on it, the latter will dissolve the former and form a viscous substance, and finally stick it to the mirror.
The cost mainly occurs in the smoothness of the viscous material. To make the reflection of the mirror uniform and parallel, the mercury on the back must be absolutely smooth - making a glass mirror takes about a month for a craftsman. But at the time, it seemed that its profit was definitely over 1,000%.
Mirrors made by silver mirror reaction are completely different. The chemical reaction directly produces a thin layer of silver on the back of the mirror. The effect is better than mercury mirrors. When the German Liebishi discovered the silver mirror reaction, the price of mirrors dropped significantly. , making it affordable for ordinary working-class families.
If confidentiality measures are taken properly, the profit of using silver mirror reaction to make glass mirrors may be 100 times.
However, although Chu Yining knew about the silver mirror reaction, she had no idea what this relatively professional Chinese cultural term meant. Huang Xuan could only look at the energy screen and explained to her: "It is to use a reducing agent to remove the silver nitrate." To reduce silver ions to metallic silver, you can use silver ammonia solution and add acetaldehyde to reduce it... "
He was only half-skilled in chemistry, and he hadn't been to school for more than half a year. He basically followed the words with half an understanding, but Chu Yining suddenly understood, stretched out his white fingers and said: "You just say restore silver to me." I know, it’s a good idea. Well... it’s a very smart ancient industry.”
Huang Xuan smiled piously, replacing the story of the wild rabbit with the Virgin Mary in his mind. He was about to go out, so he had better behave.
Chu Yining was already very anxious. Unlike Huang Xuan, she and Huang Xuan's time was calculated in standard time, which is the time a person actually lives. As a new member of the Management Bureau, it is not a small matter to disappear quietly for half a year.
With Huang Xuan as a know-it-all, Chu Yining relaxed a little and said, "How much do you think mirrors cost now? Also, will making mirrors affect the production of porcelain?"
Huang Xuan shook his head slightly and said: "It's already the 18th century. Silver nitrate is already available. It's just a matter of finding a few real people. If we don't stay long, we can produce some luxury goods. No matter how troublesome the industry is, Still in agriculture, the return rate is too low.”
Chu Yining thought that Huang Xuan was alluding to the three-field rotation farming she once said, and her face turned red and she said: "Since you are so sure, then do it yourself, and don't find an honest person. Tens of thousands of thalers , I’m afraid it will change easily.”
Huang Xuan was stunned for a moment and said honestly: "I don't know how."
"Can't do anything?"
"Make a mirror." Huang Xuan said without any embarrassment: "I am the kind of person who is said to have extremely poor hands-on skills. Regardless of whether it is silver nitrate or gold nitrate, I can't do it."
Chu Yining was surprised at first, but said nothing amid Huang Xuan's anxiety. She turned to someone to ask for directions and walked towards the store selling mirrors. What she was thinking about was the origin of Huang Xuan. From the bottom of her heart, travelers never believed in small-probability events. If such a thing happened to happen, it basically did not exist in terms of the history of the plane, so even if she occasionally Think about it: Huang Xuan may "happen" to know the history of this plane, but in the blink of an eye, she will throw away similar thoughts in shame - without strong accumulation, how could it be a coincidence? How come she never happened to arrive there? How about living in such a familiar world? How could Huang Xuan happen to know the history of two different planes
By extension, Chu Yining had to reconsider which family could cultivate a person like Huang Xuan - and what she did in Venice, Chu Yining also regarded it as her own recklessness. .
Huang Xuan, who was walking behind, didn't know that Chu Yining gave him a completely different evaluation because of his extraordinary performance.
In fact, Huang Xuan doesn't understand what a truly normal performance should be.
The Nengdun barren zone is an area with no profit at all. That is to say, Huang Xuan of that day would dig it up and dig it out like a treasure. But he turned his head and looked at it again, and the two mouths moved. Through the trillions of thermal circles borrowed by Mr. Comas from the R plane, the interest earned every year is 4%, which is almost 10 billion thermal circles. How many time travels in the P plane do you need to make back? What's more, he always uses the resources of one or two bases. If they were placed in the plane world, just by renting these bases to other travelers, he would make more money than he could use himself.
Therefore, ordinary people will not travel to the P plane at all. For most people, going to the P plane is like going to the frontiers of Xinjiang and Tibet to do business. It is hard work, high cost, and the profit is meager. Under such circumstances, the similarity of the P plane is maximized. degree of retention.
As for the planes that Chu Yining once visited, countless travelers visit them every day. Even the similarity is not stable, so how can we make a clear historical judgment.
Chu Yining regards the trial time and space of P001 as those planes that can make people rich. Since he has no plane to refer to, the result of his judgment is of course not very accurate.
Of course, as an experienced traveler, Chu Yining only gave a preliminary impression. The so-called bold assumptions must be carefully verified. If not, he would have found a way to deal with Huang Xuan when he was in Venice.
The two travelers had their own thoughts and became even more lazy under the warm sunshine.
Chu Yining walked proudly under the eyes of many men, without any discomfort. Huang Xuan admired her, but at this moment, she felt a little alienated. She probably shared hardships and blessings. Question.
The two of them were about to solve the problem at hand, and the main conflict naturally focused on the Space-Time Management Bureau and the advanced training materials they wanted.
Huang Xuan followed Chu Yining step by step. In the eyes of many Germans, he was probably still a slave from the East, but he didn't care much about this.
Following Chu Yining in a daze, Huang Xuan felt a little delirious as he watched her ask for details about the mirror, and watched her order ammonia and silver reagents in the market.
Chu Yining seemed to be confused about how to deal with Huang Xuan, and the two of them returned to the palace in silence.
…
It took Betege two months to bake porcelain that satisfied Augustus II, and Chu Yining himself also successfully made a silver mirror reaction. In the following time, they not only He was rewarded by Augustus II Vantale and began to share in the profits from porcelain.
Just like Augustus II did in history, Betegue, Huang Xuan and Chu Yining will get permission to establish a porcelain factory belonging to the royal family and take away 30% of the profits - although It was just profit rather than sales, but even so, they got 6,000 thalers in the first month. White hard porcelain was welcomed by almost all of Europe. In this situation where Chinese porcelain was in short supply and people were far from sophisticated enough to distinguish Kangxi porcelain from Saxon porcelain, they were even able to sell their products at the same price as Chinese porcelain.
In fact, even without Huang Xuan, the Meissen Porcelain Factory produced products with its own brand, but that was after 184. At that time, everyone in Europe knew that white porcelain came from Saxony, and it completely lost its huge profits. After receiving support from the government, the Germans gave up the act of piracy of Chinese porcelain and changed the Chinese landscape paintings, Chinese flowers and birds on the porcelain to white porcelain with a German style.
Almost at the same time, more beautiful silver mirrors also began to be sold to businessmen from Berlin, Hamburg, and further afield, Austria and Prussia.
The initial profit was not much. In two weeks, Chu Yining made 600 mirrors, but only sold 5 of them. The 100-thaler silver mirror made businessmen hesitant. Gentlemen in the 18th century were concerned about The acceptance of new things is limited, at least we cannot accept 100-thaler experiments.
However, when those five mirrors were quickly sold in Hamburg and Berlin, the silver mirrors were sold faster and faster.
On the other hand, Schwein's process of opening the road went smoothly. Chu Yining selected a dozen serfs with family backgrounds and bought them from the manor owner, asking them to cut down a lot of wood every day. Thrown into the halo of the jungle.
It seems that everything is normalizing. Huang Xuan even believed that even without the help of energy, he could still be a happy hare here.
However, as time went by, after spending several months in the 18th century, both Huang Xuan and Chu Yining began to lose their composure.
The hired workers had cut down the entire forest. Chu Yining even entrusted some trading houses to purchase coal from other places, then transported it to the forest by carriage and threw it into the halo. For a whole month, Huang Xuan did not control the financial power. It is also conceivable that more than 80% of the total income, at least 100,000 thalers, has been thrown into the halo. Especially in the past month, more than a dozen serfs have been throwing wood, coal and charcoal into the halo almost non-stop. In the middle, as long as a corner of a huge tree trunk is dragged into it, it will be swallowed up. The serfs also drive the horses directly through the halo. The coal will disappear on the ground along with the back of the carriage, leaving behind a pile of tinkling metal scraps. and two silly horses.
Even so, there seems to be no movement at all in the so-called trial plane.
Huang Xuan unconsciously thought that Chu Yining seemed to have never cared about him again and returned to a state of great concern. (To be continued. If you want to know what happened, please log in to .qidian. There are more chapters. Support the author and genuine reading!) (To be continued)
