658. Chapter 658 Mother-in-law and daughter-in-law are united
A few pieces of glass are far more satisfying to Haitang than a few pieces of gold.
After all, you created it yourself, which is a completely different feeling.
Now that glass is available, it is an important raw material for making silver mirrors.
Haitang knew that if she wanted the glass to become clear and transparent, she just had to add some manganese dioxide when it melted, but she didn't have it and couldn't find it.
Now, all we need are the additional materials to make the mirror.
There are two ways to make a silver mirror. One is to use tin foil and mercury. Place the tin foil on the glass and pour mercury on it. The mercury can dissolve the tin to form a tin amalgam. Once it dries, it becomes a mirror.
However, this production method takes a long time, is not durable, is afraid of water vapor, and is prone to damage.
Moreover, mercury is toxic and is not suitable for long-term exposure.
Haitang decided to adopt the second method.
It took her a day to find what she needed, silver nitrate, sodium hydroxide, ammonia, and glucose.
The other crabapples were produced by mixing the existing chemical raw materials, mainly glucose. The crabapples needed to be extracted, but they did not have any stored grapes. They were all gone on the trees this season. The crabapples went from house to house and finally found some.
When everything was ready, Haitang wiped the glass clean, put it into a rubber bucket, poured it into the silver nitrate solution, and added some sodium hydroxide. Gradually, a gray precipitate formed.
Haitang watched eagerly, waiting, expecting...
When gray precipitate is seen, Haitang immediately adds ammonia water and stirs gently until the gray precipitate is completely dissolved. Finally, add glucose solution.
Glucose solution is also necessary, because glucose has the ability to "restore" and can reduce the silver ions in silver nitrate into metallic silver particles. These silver particles are deposited on the glass to make a silver mirror.
After about half an hour, the silver mirror has formed. Begonia rinsed it with water and wiped it dry.
The face in the mirror was clearly visible, and Haitang saw her true self for the first time...
Touching her cheek, she smiled happily and gratifiedly.
It turns out that I, the little woman, still have some use in this era and can become a little chemist.
Haitang thought for a while, and in order to enhance the durability of the mirror, he also painted a layer of protective paint on the silver layer after silver plating, so that the silver layer would not easily fall off and be damaged.
In this way, it will be even more flawless.
Soon, more than a dozen mirrors were all produced in the same way.
In the past few years, Haitang has been busy making these things, and her mother-in-law has given her great support. She guards the door every day and does not let anyone disturb Haitang.
Even when Datong wanted to say hello to Haitang, her mother-in-law asked Datong to go back to the house and wait. When Haitang was done with her work, she would naturally go find her.
It has not happened all these years that the old lady "loves and cares" her daughter-in-law like this. Why did the mother-in-law and daughter-in-law suddenly become of the same mind?
Tian Niu can’t understand it, Er Tong can’t understand it, even Lamei can’t understand it...
The old lady has changed so much and so quickly since she came back, and I haven’t said anything yet...
Haitang finally came out of her "laboratory".
The mother-in-law was originally looking forward to getting her hair dye, but she was disappointed when she saw that what Haitang was holding was a mirror.
What made her even more disappointed and angry was looking at herself in the mirror. Her wrinkled old face looked like tree bark, and her hair was mostly white...
