Chapter 1967: Solutions for mercury poisoning
Despite the face mask, the smell of urea emitted from cooking urea made Marin sick. However, because the manufacture of silver mirrors is highly confidential, Marin is not willing to fake others. Therefore, he was so disgusted that it was considered self-reliance.
The silver mirror made from the silver mirror reaction made by silver should not be too good. Take it for Angela, Angela obviously feels that the mirror is much brighter, and the self in it is more bright and moving.
"Okay, this mirror is very safe. You can use it with confidence. However, let alone I made it, I said it was bought from Venice." Marin urged him to order it to be identical to the original mirror Silver picture frame.
Marin went to buy a Venetian mirror in order to copy the Venetian mirror in the cottage so as not to cause doubt. After the mirror was bought back, several very 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 be pressed on the spiral die-casting machine into the same pattern and sculpture as the silver mirror frame of the Venetian glass mirror. Because the material of silver is soft, although the silver frame used for Venetian glass mirrors is not pure silver and not so soft, it is also softer than copper and easy to suppress.
Then, the mercury-tinned tinted Venetian glass mirror I bought from Venice at a high price was naturally retired. Of course, it is still useful ...
"I plan to send this mirror to Huaxia and dedicate it to the emperor of Ming Dynasty ..." Marin decided to use waste and exchange this mirror for profit.
"But, don't you say that there is mercury gas?" Angela didn't understand.
Malin smiled:
"It has been several months since this mirror was sent to Ming Dynasty, at least half a year has passed. Basically, the influence of poisonous gas is very small."
In fact, the mercury-tinned tin foil glass mirror is the most dangerous in the first three months. It really takes six months to pass. As long as it is not holding the mirror to sleep, the harm is not great. It's just that with such a good mirror, a woman doesn't hold her to sleep, it seems unlikely that ...
"You still have to think of ways to make people less vulnerable!" Angela is kind and feels that her man has many ideas, so she wants to help others.
Angela knows that Marin intends to make huge profits by making this glass mirror. 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 Angela ’s own silver mirror, Marin said it was difficult to do, and he did not want to do it again for a long time (mainly disgusting).
Fortunately, the foreigners said, but domestic people, Angela did not want them to be harmed. In particular, Angela can think of using toes, and those who use this kind of mirror in the future will definitely be domestic ladies. Many ladies in the North Sea have good relations with Angela. Therefore, Angela does not want them to be poisoned by the mirror ...
"Less subject to some hazards ... reduce toxic hazards?" Marin fell into contemplation ...
……
In the final analysis, the main hazard of mercury-tinned glass mirrors is the mercury poisoning caused by the residual mercury vapor being inhaled into the human body. If you want to reduce the harm, you must clean up the residual mercury ...
How to remove or neutralize the harm of mercury? Marin thought for a moment ...
"What is mercury reacting to? What sodium thiosulfate seems to be used in later generations? By the way, mercury is often 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 generations of chemistry teachers said that if mercury is overturned, sulfur is generally neutralized to produce non-toxic mercury sulfide?"
……
After thinking for a long time, Marin finally thought of a way to clarify the effect of mercury vapor, that is, bury the glass mirror in the sulfur powder, and then, heat it at medium temperature to force the mercury vapor to volatilize and react with sulfur to generate mercury sulfide, which is cinnabar ... …
Although this may not be able to clear the mercury composition, but after processing, it can basically reduce toxicity and avoid users from being poisoned.
Angela was right, this thing will be used by the noble ladies in the North Sea in the future. Therefore, proper processing is necessary to reduce toxicity. After all, Marin cannot poison himself.
As for using silver-plated glass mirrors for domestic ladies, that's no need to think. Why? Will leak!
The effect of silver-plated glass mirrors is significantly better than that of mercury-tinned tin foil glass mirrors. The picture of the mercury tinned glass mirror is dark, while the picture of the silver plated glass mirror is very bright.
Angela, as the Grand Duchess of the North Sea Kingdom and the Queen of the United States, uses high-end glass mirrors, and those ladies in the North Sea Kingdom will not feel abnormal. After all, people are queens, shouldn't they use advanced things? Mrs. Mary's use is also very normal, after all, "Lady Queen Lafayette". But if there is one lady from Beihai, it will be abnormal ...
If a foreign lady came to visit, they took out the mirror and compared it.-Oh, the mirror I bought in Venice at a high price is not as good as the mirror used by ordinary ladies in the North Sea country?
In this way, the fact that Beihai has mastered better mirror-making technology must be spread. When the time comes, Venice will also find Malin—have you stole our technology?
France will also find fault, because France is the most smelly country, and there is a great demand for mirrors ~ www.wuxiaspot.com ~ also has the highest requirements. In order to save costs and mass production, France may be able to unite with other countries and force the North Sea State to hand over the secret ...
Therefore, before his own strength is not strong enough, Marin only intends to produce mercury tinned glass mirrors for the time being and make a fortune behind Venice. At that time, even if others are jealous, they will only be jealous of Venice. After all, the gun shot the bird. For Marin, it is enough to quietly follow the fortune.
Of course, it is also very important if customers can enjoy health. In particular, those noble ladies in Beihai.
These people will bear the responsibility of giving birth to the nobles of the North Sea. In case of mercury poisoning, the child may be deformed. Marin did not 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 throwing the entire glass mirror in sulfur powder and heating it, mercury vapor and mercury sulfide generated by sulfur easily generated red spots on the back of the mirror. Obviously, it was vermilion.
At the same time, the frame made of silver is also easy to turn black. Obviously, even after heating, even the silver with relatively stable properties produced some trace reaction with sulfur, resulting in few gray-black silver sulfides ...
To this end, Marin also gave a solution-when the mercury tinned glass mirror was placed in sulfur powder and heated, the silver frame was first dropped, and only the glass mirror itself was thrown into it. Then, if there are small red spots on the back of the mirror, you can reapply the paint again, which can cover up ...
