The Rise of the European Emperor

Even though he had already worn a mask, the smell of urea from cooking urea still made Marin feel sick. However, because the manufacture of silver mirrors is highly confidential, Marin is not willing to fake it. Therefore, he was disgusted like this, and it was his own fault.

The silver mirror made by the reaction of the silver mirror made of silver, the effect should not be too good. After using it for Angela, Angela obviously felt that the mirror was much brighter, and the self inside was also brighter and more attractive.

"Okay, this mirror is very safe, don't worry about using it. But don't say that I made it, but also that it was bought from Venice." Marin reminded, and ordered someone to order it exactly the same as the original mirror. Silver frame.

Marin went to buy a Venetian mirror in order to copy the Venetian mirror, so as not to be suspicious. After the mirror was bought back, several reliable craftsmen began to copy the patterns and carvings on the silver frame of the Venetian glass mirror.

Subsequently, the craftsmen directly created a copper mold, which can press the silver slats into the same patterns and carvings as the silver frame of the Venetian glass mirror on a spiral die-casting machine. Because the material of silver is soft, although the silver frame used in Venetian glass mirrors is not pure silver and not so soft, it is also softer than copper and easy to suppress.

Then, the Venetian glass mirror with mercury and tinfoil that I bought from Venice at a great price before, naturally retired with honor. Of course, it still works...

"I plan to send this mirror to Huaxia and dedicate it to the emperor of the Ming Dynasty..." Marin decided to use waste and take this mirror in exchange for benefits.

"But, didn't you say that there is mercury gas?" Angela was a little confused.

Marin smiled:

"This mirror has been in the past for several months, and it will be at least half a year before it is sent to the Ming country. Basically, the impact of the poisonous gas is very small."

In fact, the mercury tinfoil glass mirror is the most dangerous in the first three months. If it takes more than half a year, as long as you don't sleep with the mirror in your arms, the harm is not great. It's just that, with such a good mirror, it seems unlikely that a woman won't sleep with it...

"You'd better think of a way to make people suffer less harm!" Angela was kind-hearted, and felt that her man had too many ideas, so she wanted to help others.

Angela knew that Marin planned to make huge profits by making this kind of glass mirror in the future. At that time, not only foreign customers will use this kind of mirror in large quantities, but many people in Beihai will also use this kind of mirror.

As for the silver mirror that Angela used herself, Marin said that it was difficult to make, and he was unwilling to do it again for a long time (mainly because of nausea).

It's okay for foreigners, but for domestic people, Angela doesn't want them to be harmed. In particular, Angela can think with her toes that the people who will use this kind of mirror in large quantities in the future must be noble ladies in China. And many noble ladies in Beihai have a good relationship with Angela. Therefore, Angela does not want them to be poisoned by the mirror...

"Less harm... reduce toxicity?" Marin fell into deep thought...

...

After all, the main hazard of mercury tin foil-plated glass mirrors is that the residual mercury vapor is inhaled into the human body and causes mercury poisoning. If you want to reduce the harm, you must clean up the residual mercury...

And how to remove or neutralize the harm of mercury? Marin thought about it...

"What does mercury react with? What kind of sodium thiosulfate seems to be used in later generations? By the way,

Mercury exists in nature in the form of cinnabar. And cinnabar is mercury sulfide..."

"It seems that sulfur can also react with mercury? Marin vaguely remembers that the chemistry teacher of later generations mentioned that if the mercury is overturned, it is usually neutralized with sulfur to form non-toxic mercury sulfide?"

...

After thinking for a long time, Marin finally thought of a way to understand the influence of mercury vapor, which is to bury the glass mirror in sulfur powder, and then heat it at medium temperature to force the mercury vapor to volatilize and react with sulfur to form mercury sulfide, which is cinnabar... …

Although this may not be able to fully understand the mercury composition, but after processing, the toxicity can be greatly reduced to prevent users from being poisoned.

Angela is right, this thing will definitely be used by noble ladies in Beihai in the future. Therefore, proper processing to reduce toxicity is necessary. After all, Marin can't poison his own people.

As for the use of silver-plated glass mirrors for domestic ladies, it is unnecessary to think about it. why? It will be leaked!

The effect of silver-coated glass mirrors is significantly better than that of mercury-coated tinfoil glass mirrors, and even fools can see it. Mercury tinfoil glass mirrors have a darker picture, while silver-coated glass mirrors have a brighter picture.

Angela, as the Grand Duchess of the North Sea Kingdom and the Queen of the United States, used higher-end glass mirrors, and those noble ladies of the North Sea Kingdom would not find it unusual. After all, she is a queen, shouldn't she use something more advanced? It is also normal for Mrs. Mary to use it, after all, it is the "Queen Dowager Lafayette". But if there is only one noble lady in Beihai Kingdom, it would be abnormal...

If a lady from a foreign country comes to visit, they take out a mirror for comparison—oh, the mirror I bought at a high price in Venice is not as good as the mirror used by ordinary ladies in Beihai?

In this way, the fact that Beihai has mastered better mirror-making technology must be spread. At that time, Venice will also find fault with Marin-did you steal our technology?

France will also find fault, because France is the most stinky country, and has a great demand for mirrors and the highest requirements. In order to save costs and produce in large quantities, France may unite with other countries to force the North Sea country to hand over the secret...

Therefore, before his own strength is not strong enough, Marin only plans to produce glass mirrors with mercury tin foil for the time being, and make a fortune following Venice. At that time, even if people are jealous, they will only be jealous of Venice. After all, the gun hits the bird first. As for Marin, it was enough to quietly follow the fortune and count the money.

Of course, it is also very important if customers can enjoy health. Especially those noble ladies from Beihai Country.

These people will take on the responsibility of giving birth to small nobles for the North Sea Kingdom. If mercury is poisoned, the child may be deformed. Marin didn't want the second generation of nobles in his country to be deformed or mentally abnormal. Therefore, it is also important to minimize the possibility of mercury poisoning.

Subsequently, Marin conducted an experiment. He found that after the entire glass mirror was thrown into sulfur powder and heated, the mercury vapor and sulfur-generated mercury sulfide tended to form red spots on the back of the mirror. Obviously, it was cinnabar.

At the same time, the frame made of silver is also easy to turn black. Obviously, after heating, even the relatively stable silver reacts with sulfur in a small amount, forming a small amount of gray-black silver sulfide...

To this end, Marin also gave a solution-when heating the mercury tin foil glass mirror in sulfur powder, first remove the silver frame, and only throw the glass mirror itself into it. Then, if there are small red dots on the back of the mirror, paint it again to cover it up...
