Chapter 547: testing the plane (9) the glass makers of the Venice era used mercury and tin foil to make glass
To put it simply, the glass was covered with tin foil and mercury was poured over it
The latter would dissolve the former and form a sticky substance, which would then be stuck to the mirror
The cost is mainly due to the smoothness of the stickiness
To make the mirror''s reflection even and parallel, you have to make the mercury on the back absolutely smooth - it takes a craftsman about a month to make a glass mirror
But at that time, the profit was definitely more than 1000 %
The mirror made by the silver mirror reaction was completely different
The chemical reaction directly produced a thin layer of silver on the back of the mirror, and the effect was better than that of the mercury mirror
When the german li bixi discovered the silver mirror reaction, the price of the mirror was greatly reduced, so that ordinary workers could afford it
If the security measures were appropriate, the profit could be 100 times higher if the glass mirror was made with the silver mirror reaction
However, although Chu Yining knew the silver mirror reaction, she did not know the meaning of this more professional chinese chemical word at all
Huang Xuan could only look at the energy screen and explain to her: "It is to reduce the silver ion of silver nitrate to metallic silver with reducing agent
You can dissolve the liquid with silver ammonia and reduce it with acetaldehyde
" His chemistry was half-baked, and he hadn''t been to school for more than half a year
He basically read it without understanding it, but chu Yining suddenly understood it
He stretched out his white finger and said," I''ll know if you can just say silver reduction
That''s a good idea
Hmm
Very smart ancient industry
" With a pious smile, she changed the story of the wild rabbit into the story of the virgin Maria
She was about to go out, so it was better to be good
Chu Yining was already in a hurry
Unlike Huang Xuan, the time of the travelers was calculated using standard time, which was the time when a person was really alive
As a new member of the administration, it was not a small matter to disappear quietly for half a year
With Huang Xuan acting like a know-it-all" color," Chu Yining relaxed a little and said," what do you think the cost of mirrors is now
Also, will making mirrors affect the production of porcelain
" Shaking his head gently, he said," it''s the 18th century
Silver nitrate is already available
It''s just a matter of finding a few real people
We don''t stay long enough to produce some luxury goods
No matter how troublesome the industry or agriculture is, the rate of return is too low
" Chu Yining thought that huang xuan was" shooting" at the three fields of rotation that he once said, and his face was red
" Since you are so sure, then you can do it yourself
Don''t look for any honest people
Tens of millions of Taler, I''m afraid it is easy to change
" Stunned for a moment, he said honestly," I won''t
""Nothing
"" Make a mirror
" Huang Xuan was not embarrassed at all
" I am the kind of person who is said to have poor manual skills
Regardless of whether it is silver nitrate or gold nitrate, I can''t do it
" Chu Yining was surprised at the snacks, but in Huang Xuan''s anxiety, he didn''t say anything
Instead, he asked for directions and walked towards the shop that sold mirrors
She was thinking about the origins of Huang Xuan, and from the bottom of her heart, travelers never believed in small probability events
Coincidentally, such things happened, and in the face of history, they were basically non-existent, so even if she thought about it occasionally, Huang Xuan might be" coincidental
" She knew the history of this plane, but in an instant, she would be ashamed to throw away similar thoughts - without strong accumulation, where did it come from
How could she have never happened to be in such a familiar world
How did Huang Xuan happen to know the history of two different planes
As a result, Chu Yining had to reconsider which family could nurture a person like Huang Xuan - and Chu Yining saw his actions in Venice as his own recklessness
Huang Xuan, who was walking behind, did not know that Chu Yining had given him a completely different evaluation because of his extraordinary performance
In fact, Huang Xuan did not understand what the real ordinary performance should be like
The To Be Able To Stop barren zone was a place where there was no profit to speak of
That day, Huang Xuan would dig it up like a treasure
But when he turned around and looked again, his lips moved
Through the three mega hot rings Mr
Comus had borrowed from plane r, he earned four percent of his annual income, about 120 billion hot rings
How many time and space trips would he have to travel in plane p to earn it back
Moreover, he used the resources of one or two bases at a time
If they were in the plane world, they would only be leased to other travelers and earn more money than he used
As such, the average person would not travel to plane p at all
To most people, going to the p plane was like going to Xinjiang and Tibet to do business on the border without a port
It was hard, expensive and profitable
In this case, the similarity of the p plane was retained to the maximum extent
In the past, chu Yining had been visited by countless tourists every day, and even the similarity was not stable
How could he have a clear historical judgment
Chu Yining regarded the testing time and space of p001 as the rich planes of To Be Able To Stop, and he did not have a plane to refer to
Of course, the result was not very accurate
Of course, as an experienced traveler, Chu Yining only gave a preliminary impression
The so-called bold assumption and careful verification is also true
If not, in Venice, he had to find a way to deal with Huang Xuan
The two distinguished travelers each had their own thoughts, and they became lazier in the warm sun
Chu Yining walked proudly under the eyes of many men without any discomfort
Huang xuan admired her, but at this moment, he felt a little distant
Perhaps it was easier to share hardships than to share happiness
The two of them were about to solve the problem in front of them, and the main conflict was naturally re-focused on the Space and time administration and the advanced training materials they wanted
Following Chu Yining''s footsteps, he was probably a servant from the east in the eyes of many germans, but he didn''t care much about it
A little dizzy, she followed Chu Yining, looked at her asking about the details of the mirror, looked at her ordering ammonia, silver reagent on the market, Huang Xuan felt a little dizzy
Chu Yining seemed to be bewildered by how to deal with Huang Xuan, and the two of them returned to the palace speechless
It took two months for bateg to produce porcelain that satisfied Augusta Ii, and chu Yining himself successfully reacted with a silver mirror
In the following time, they not only received a reward from Augusta Ii''s 20,000 Taler, but also began to share the profits from the porcelain
Just as Augusta Ii had done in history, Bateger, Huang Xuan, and Chu Yining would get permission to build a porcelain factory belonging to the royal family and take 30 % of the profits - although only profits, not sales, but even so, in the first month, They also got 6000 Taler
White" color" hard porcelain was welcomed almost all over europe
In a situation where the supply of chinese porcelain was in short supply and people''s knowledge was far from distinguishing Kangxi porcelain from Isaacson porcelain, they could even 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 1834
At that time, everyone in europe knew that white porcelain came from Isaacson, and after completely losing the support of the huge profits, Only then did the germans give up the act of pirating chinese porcelain and changed the chinese landscape painting and chinese flowers and birds on the porcelain into white porcelain with german style
Almost at the same time, more beautiful silver mirrors began to be sold to merchants from Berlin, hamburger, and further Austria and prussia
The initial profit was not much
In two weeks, Chu Yining made 600 mirrors and actually sold only 5
The 1200 Taler silver mirrors made businessmen hesitate, and the 18th century gentlemen were limited in their acceptance of new things
At least we can''t accept the 1200 Taler test
However, when the five mirrors were quickly sold in hamburgers and Berlin, the silver mirrors were sold faster and faster
On the other hand, the process of opening the road for shi weiyin was also very smooth
Chu Yining selected more than a dozen family serfs and bought them from the owner of the farm, so that they could throw the many felled wood into the halo of the forest every day
It seemed that everything had become normal
Huang Xuan even believed that he could be a happy wild rabbit here, even if there was no energy to help him
However, over time, after three months in the 18th century, huang xuan and Chu Yining began to lose their cool
The employees had already cut the entire forest open, and Chu Yining had 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 have the financial power, and a rough estimate would be able to think that more than 80 % of the total profits
At least 100,000 Taler were thrown into the halo, especially in the past month, a dozen serfs threw wood, coal, and charcoal into the halo without stopping
As long as a corner of the huge trunk was dragged into it, it would be swallowed up, and the serfs drove the horses directly past the halo
Coal would disappear to the ground with the carriage hanging from behind, leaving behind a pile of broken metal and two silly horses
Just like that, the so-called trial plane didn''t seem to move at all
Unconsciously, chu yining''s attitude towards herself seemed to have returned to a state of great concern
