Although he had already put on a mask, the urea smell emitted when cooking urea still made Marin feel disgusted and vomited. However, because the creation of silver mirrors is highly confidential, Marin is not willing to pretend to be others. Therefore, he was disgusted like this, which can be considered as his own suffering.
The silver mirror made with silver mirrors made of silver should not be too effective. Use it for Angela. Angela obviously feels that the mirror is much brighter and she is more bright and charming.
"Okay, this mirror is very safe, don't worry about using it. But, let alone I made it, I also bought it from Venice." Marin reminded, and asked someone to customize a silver frame that was exactly the same as the original mirror.
Marin went to buy Venetian mirrors to copy Venetian mirrors so as not to make people suspicious. After the mirror was bought, several reliable craftsmen began to copy the patterns and carvings on the silver frame of the Venetian glass mirror.
Then, the craftsmen directly created copper molds, which could press silver slats on a spiral die-casting machine to make patterns and engravings the same as the silver frame of the Venetian glass mirror. Because the material of silver is softer, although the silver frame used in Venetian glass mirrors is not sterling silver and is not that soft, it is also softer than copper and easy to press.
Then, the mercury tin foil-plated Venetian glass mirror I bought from Venice at a high price was naturally retired gloriously. Of course, it is still useful...
"I plan to send this mirror to China and offer it to the Emperor of the Ming Dynasty..." Malin decided to use the waste and use this mirror for profit.
"But, didn't you say there was mercury gas?" Angela didn't understand.
Marin smiled:
"It has been a few months since this mirror. If you send it to Mingguo again, at least half a year has passed. Basically, the impact of poison gas is very small."
In fact, the mercury tin foil glass mirror is the most dangerous in the first three months. It will take more than half a year to go on. As long as you don’t sleep in the mirror, the harm is still not great. However, it seems that a woman doesn’t sleep in such a good mirror, it seems that it is not very likely that a woman will sleep in the arms...
"You'd better think of a way to help others less harm!" Angela was kind-hearted and felt that her man had many ideas, so she wanted to help others.
Angela knew that Marin planned to make huge profits by making this glass mirror in the future. At that time, not only foreign customers will use this mirror in large quantities, but many people in the Beihai will also use this mirror.
As for the silver mirror Angela used by herself, Marin said that it was difficult to do it and she was unwilling to do it for a long time (mainly disgusting).
It’s okay for foreigners to say, but Angela doesn’t want them to be harmed by the people in China. In particular, Angela can think of it with her toes that those who use this kind of mirror in the future will definitely be ladies in China. Many ladies in Beihai have a good relationship with Angela. Therefore, Angela doesn’t want them to be poisoned by the mirror...
"Avoid less harm...reduce toxic hazards?" Marin fell into deep thought...
...
After all, the main harm of the glass mirror with tin foil plated in mercury is that the residual mercury steam is sucked into the human body and causes mercury poisoning. 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 is used in later generations? By the way, mercury often exists in the form of cinnabar in nature. And cinnabar is mercury sulfide..."
"It seems that sulfur can also react with mercury? Marin vaguely remembers that it seems that later chemistry teachers mentioned it and said that if mercury is overturned, it will generally be spread to neutralize sulfur to produce non-toxic mercury sulfide?"
...
After thinking for a long time, Marin finally came up with a way to understand the impact of mercury vapor, which was to bury the glass mirror in sulfur powder, then heat it at medium temperature to force the mercury steam to evaporate, and react with sulfur to form mercury sulfide, which is cinnabar...
Although this may not be able to clearly understand the mercury composition, after processing, it can basically significantly reduce the toxicity and prevent users from being poisoned.
Angela is right, this thing will definitely be used by the noble ladies in the North Sea in the future. Therefore, it is necessary to process it appropriately and reduce the toxicity. After all, Marin cannot poison his own people.
As for using silver-plated glass mirrors for domestic ladies, there is no need to think about it. Why? It will leak the secret!
The effect of silver-plated glass mirrors is significantly better than that of mercury-plated tin foil glass mirrors, which can be seen by fools. The picture of the mercury-plated tin foil glass mirrors is dark, while the picture of the silver-plated glass mirrors is very bright.
As the Grand Duke of the Beihai Kingdom and the Queen of the United States, Angela used higher-end glass mirrors, so those noble ladies of the Beihai Kingdom would not feel abnormal. After all, they are queens, so it is not appropriate to use higher-end things? It is normal for Mrs. Mary to use it, after all, she is "The Queen Mother of the Queen Mother". But if everyone in Beihai Kingdom has one, it would be abnormal...
If a foreign lady comes to visit, people will take out the mirror and compare it - Oh, the mirror I bought in Venice at a high price is not as good as the mirror used by ordinary ladies in Beihai?
In this way, the Beihai Kingdom will definitely spread the problem of mastering better mirror making technology. At that time, Venice will also find fault with Marin - are you stealing our technology?
France will also find faults because France is the most beautiful country, with great demands on mirrors and the highest requirements. In order to save costs and mass production, France may join forces with other countries to force the North Sea to hand over the secrets...
Therefore, before his own strength is not strong enough, Marin temporarily only plans to produce mercury tin foil-plated glass mirrors to follow Venice to make a fortune. At that time, even if people are jealous, they will only be jealous of Venice. After all, guns will hit the birds. And Marin quietly makes money and counts money.
Of course, it is also very important to allow customers to enjoy health. Especially those noble ladies in Beihai Country.
These people will assume the responsibility of giving birth to small nobles for Beihai Country. If mercury is poisoned, the children born may be deformed. Marin does not want the second generation of nobles in his country to be deformed or have abnormal intelligence. Therefore, it is also very important to minimize the possibility of mercury poisoning.
Later, Marin conducted an experiment. He found that after throwing the entire glass mirror into sulfur powder and heated it, mercury sulfide produced by mercury steam and sulfur can easily create red spots on the back of the mirror. Obviously, it was cinnabar.
At the same time, the borders made of silver are also prone to blackening. Obviously, after heating, even silver with relatively stable properties has some trace reaction with sulfur, resulting in a small amount of gray-black silver sulfide...
