Li Zhi was overjoyed when he saw the old Taoist priest refining mercury, so he said, "Daoist Cao, I want to use a large amount of mercury, how about you refine mercury for me in the future?" I'll give you four taels of money a month, and three meals with meat. Pen %Fun %Pavilion www.biquge.info"

When Cao Shoudao heard Li Zhi's words, his face was embarrassed, and he said: "My lord, Xiaodao is busy refining pills every day, and he is asking for the way of immortality, I am afraid that he can't refine mercury for adults." Looking at Li Zhi's face, Cao Shoudao said, "Why don't I sell this method of refining mercury for one hundred taels to the adult, and the adult will find someone else to operate it?" ”

Li Zhi looked at Cao Shoudao and felt that this Taoist priest was quite good at making money, and it was a hundred taels as soon as he opened his mouth. Li Zhi smiled and said, "One hundred taels is too expensive, and the Taoist chief is cheaper." ”

Cao Shoudao looked at Li Zhi and said, "This method of refining mercury is also a secret method of my master, and there are many key details. Unlike other methods, my secret method can screen out impurities in cinnabar, extract pure mercury, and ensure the safety of the operator. I'll sell it to an adult for a hundred taels, which is considered cheap. If it is lower, I will be sorry for the first teacher of the sect. ”

It turns out that his secret method can also remove impurities from the cinnabar, which is indeed more valuable. Seeing that he said it in a good way, Li Zhi stopped bargaining and said, "Then one hundred taels, I'll buy you this method." But you have to follow me to Fanjiazhuang and teach this method to my people until they can operate independently. ”

Cao Shoudao said: "That's nature. ”

After solving the source of mercury, Li Zhi bought some tin blocks in Tian0jin City and returned to Fanjiazhuang to start trial production of glass mirrors.

Li Zhi found a few pieces of tin, cut them open and threw them in the mercury. Tin is soluble in mercury, but the tin block will form a dense oxide film in the air, and with this oxide film, tin cannot dissolve in mercury, so it should be cut. However, Li Zhi waited in the room for a while and found that it dissolved very slowly.

With such a dissolution rate at room temperature, it would take a long time for tin and mercury to fuse together, and Li Zhi couldn't wait.

Li Zhi simply put the mercury and the tin pieces cut into small pieces into a small clay pot and heated them in the courtyard over low heat. The boiling point of mercury is more than 300 degrees Celsius, and the temperature of low heat heating is lower than 300 degrees, which only allows the mercury to turn into a liquid state, and will not let the mercury boil. However, mercury will also volatilize below the boiling point, and its vapor is highly toxic, so Li Zhiren walked far.

When the mercury and tin had melted, Li Zhichang took a breath, then walked over with bated breath and extinguished the fire in the small furnace.

Li Zhi held his breath and stirred the liquid mercury and tin with a stick, and found that the two had dissolved into a tin amalgam alloy.

Li Zhi held his breath for a while, then walked to the distance to breathe, and then came back to operate. After running back and forth like this ten times, Li Zhi found that the tin amalgam had cooled and solidified, becoming a solid metal.

Li Zhi went to the glass workshop and took a piece of flat glass the size of a human face and used it as a template for the mirror.

He returned to the yard and heated the molten tin amalgam again. Waiting for the tin amalgam alloy to turn into liquid, Li Zhi found a small brush, held his breath and brushed the tin amalgam alloy on the side of the flat glass, brushing several thick layers.

Every few brushes, Li Zhi has to go to a distance to breathe, and it took Li Zhi a quarter of an hour to brush the glass with a large face.

Then the tin amalgam on the glass of Li Zhi and others solidified. After waiting for half an hour, the tin amalgam on the glass turned solid, and Li Zhi lifted the piece of glass to look at it and saw his face clearly.

After traveling for so long, Li Zhi saw his appearance clearly for the first time. Li Zhi's first reaction was how this face was so similar to his self before the crossing, at least eight or nine points similar. If the two faces appear one after the other, I am afraid that others will think that they are the same person.

The mirror was not as bright as the aluminum mirrors of later generations, a little darker, but it was enough to see the color of his own hair and complexion. It is said that it is darker than the mirrors of later generations, compared to the bronze mirrors that can only see the shadow of a person in this era, it is more than a little better.

This mirror is a success.

Li Zhi was in a good mood, and used a brush to coat the tin amalgam coating on the back of the mirror with several thick layers of tree paint as a protective layer, and the mirror was completed.

made this glass mirror, and Li Zhi sent it to Cui He first.

Cui He was embroidering in the house, and when he saw the glass mirror that Li Zhi had brought over, he blinked his eyes as if he didn't believe it.

"Is there such a clear mirror in the world? You can really see your eyelashes clearly! ”

Li Zhi said: "I didn't cheat! ”

Cui He looked left and right in the mirror, never got tired of looking at it, and said, "So I was born so good-looking? ”

Li Zhi smiled and said, "My lady is the most beautiful!" ”

Cui Heyan's face was overjoyed, and he blushed a little, and he was embarrassed to look in the mirror again. After thinking about it, Cui He said: "Husband is so powerful! ”

Li Zhi smiled: "This little mirror is given to you, you can study it slowly!" Wait until I make a big mirror, and then I'll give you a big mirror. ”

Cui He happily took the mirror and carefully placed it on the table.

After the experiment made the mirror, Li Zhi began to organize mass production.

This glass mirror is an absolute luxury in this era, and Li Zhi decided to sell it for a high price, so he naturally had to pay attention to secrecy. Li Zhi decided to separate the raw material configuration of the mirror, tin amalgam melting, tin amalgam brushing the mirror surface and brushing the lacquer protective layer, and each process was handled by one person. In this way, even if someone buys one or two workers, they will not know how the mirror is made.

Of course, Li Zhi also controls the secret recipe from the source - transparent glass can only be produced by Li Zhi, and mirrors cannot be produced without large pieces of transparent glass.

Li Zhi found five workers to produce mirrors. Li Zhi does not need this kind of mirror, the output is very high, five people can produce twenty large and small mirrors a day, which is enough for Li Zhi to sell.

Seeing the mirror produced by his own hands, the five workers looked up and down around the mirror, and they were indescribably surprised. It turns out that there is such a clear mirror in the world, and there is no visible mirror. The workers were amazed at the general, and they did not understand how the general could come up with such a clever method.

The general must be Lu Ban, right?

Li Zhi took the produced mirror to his subordinates to observe, and Li Xing's first reaction when he saw the mirror was to hide to the side.

"Big brother, this is a demon law, put my face in it!"

Li Zhi chirped: "What kind of demon law, do you understand the mirror?" ”

Li Xing looked at it for a while and grinned in the mirror.

Zheng Kaicheng looked at the mirror for a long time and exclaimed: "My lord, this mirror is too clear, I finally know what I look like!" ”

Li Laosi looked at the mirror and exclaimed: "The owner is so powerful that he can produce such a mirror!" It's sure to sell! ”

Zhong Feng grabbed the mirror and looked at it for a while, and said, "My lord, this mirror is so good, give me a small one." ”

Li Zhi divided the mirrors into three types, the first is a small mirror the size of a palm, which is mounted on the lid of a wooden box, which can be carried around and costs ten taels.

The second is a mirror the size of a human face, in which you can see your entire face clearly, and the outside of the mirror is wrapped in a copper frame, and the price is thirty taels.

The third is a one-meter-high clothing mirror, which can see all of your body clearly in the mirror, and the outside of the mirror is wrapped in a wooden frame, and the price is one hundred and fifty taels.

Of course, to do a good job of mirroring, you also need to do a good job of marketing. Otherwise, if you put the slick mirror in the store and sell it, you don't know how long it will take for it to be accepted by the rich and customers will buy it. The best way for customers to know about this new product is to let the top of society make this product popular first.

On February 28, Li Zhi made 30 well-dressed mirrors more than 1 meter high, sent people to the capital, and presented them to the Son of Heaven.
