The complacent Wang Ke returned to his home, walked into the living room but didn't see anyone, this time is not too early, it stands to reason that his wives should also be at home.

Today made two telescope samples, the one in Li Ke's hand has now reached the hands of Comrade Li Er, Wang Ke did not take this out, before getting out of the car and entering the imperial study, Wang Ke did not take the telescope he was holding down the car at all, 'getting' when he went home just now, Li Ke sat in the car and Wang Ke spent a long time talking, wanting to take it away was rejected by Wang Ke, Wang Ke wanted to go home to show off to his wife and son.

But now Wang Ke can't see a single figure, how does this make him show off, and to whom. Wang Ke unconsciously began to be a little discouraged in his heart, he didn't know where these people had gone, even if they went to the fashion workshop, it was said that they should come back at this time.

Wang Ke had no object to show off, so he had to walk upstairs to his study depressedly, and when he walked to the 'door' of Nanping's room, the sound of laughter from the house made Wang Ke understand that his three wives were chatting in Nanping's house. At this time, Wang Ke's heart wanted to show off again, and he didn't knock on the 'door', Wang Ke directly pushed the 'door' and walked in, startling several people in the room.

Wang Ke couldn't hide the pride in his heart, stretched out his hands behind his back, and showed the telescope tightly in his hands to his wives.

Nanping they only saw Wang Ke busy all day long, and never knew what he was busy with, and today finally brought something back for them to see, of course, they were very happy, and they all came around one by one, rushing to ask Wang Ke to show it to themselves first.

Wang Ke didn't care which of them could grab it, he put the telescope on the table in the room and sat down, and with a wave of his right hand, he thought about putting it on the table.

But Wang Ke was proud as soon as he entered the room, and he didn't notice that there was still Nanping's bronze mirror on the table, and with a wave of his hand, he just swept the bronze mirror standing on the frame on the table to the ground, making a loud noise, and the little Wang Kun, who was lying on the 'bed' and playing, was also frightened and cried "wow".

The sound of the bronze mirror falling to the ground, and the cry of Xiao Wang Qi made Nanping lose the mood to look at the telescope, and hurriedly ran to the 'bed' to coax Xiao Wang Kun, Wang Ke also quickly bent down and picked up the bronze mirror.

In his hand, the bronze mirror is still quite weighty, Wang Ke doesn't comb his hair on weekdays, and he doesn't feel it, but today he knows that his wives have to dress up on weekdays, and if they want to look in the mirror, it's really a physical job.

Weighing the weight of the bronze mirror, Wang Ke thought to himself: "Such a heavy thing, I can't see it clearly, if only there was a glass mirror!" ”

Thinking of this, Wang Ke suddenly remembered that there were several pieces of flat glass in the glass workshop, because it was useless at that time, the craftsmen originally wanted to return to the furnace, but they were stopped by their own ghosts and let them put aside, and they didn't think of what to do at that time, but now it seems that it can be used to make several mirrors.

Thinking of this, Wang Ke immediately stood up and walked out quickly, he was anxious to go back to his study and write down the method he knew how to make glass lenses, and see which method could be made with the technology of this era.

While walking, Wang Ke was glad that his mother in later generations was an engineer engaged in chemical engineering, and when he was fine, he once talked to himself about the origin of glass mirrors and various processes, and he listened to it in his ears at that time, because he didn't expect that he would make this thing, that is, when the story was listening, I don't know how much I remember now.

Watching Wang Ke hurriedly walk out, the three 'women' didn't know what Wang Ke remembered again, but they didn't see the unhappy expression on Wang Ke's face, and they also knew that Wang Ke wouldn't have any other thoughts, but could only think of something, plus the telescope in his hand, so he didn't care about what Wang Ke was thinking. When Nanping coaxed Xiao Wang Yu not to cry, he also ran over, and followed Lanling and Dongyue to see how fun this telescope was.

Wang Ke walked into the study and sat down, took out a pen and paper, and then held his chin and remembered there, as long as he remembered a little, he would write it down first, after all, this time was a little long, and the things in his memory were also a little vague and 'mixed' and 'chaotic', Wang Ke has always dealt with this situation, he wrote it down first when he thought of it, and then recalled it in depth with what he had memorized, so that he might be able to recall it more.

Sitting there until Nanping came to call for dinner, Wang Ke reluctantly walked out, and after eating, Wang Ke immediately flashed back to the study, making the family 'overwhelmed', I don't know what kind of nerves he is having today.

The time has passed, Wang Ke finally raised his head buried on the desk, judging from Wang Ke's expression, he is already quite satisfied with the matter of making glass mirrors.

In fact, for the production process of glass mirrors, if in later generations, Wang Ke does not need to be so troublesome at all, as long as he looks on the Internet, he can find a lot of them immediately, but now in this era when there is no electricity, don't go to the luxury of these, even if the network can be crossed, there is no electricity This network is also white, and there is no use.

Wang Ke stretched his waist, now he has to go to bed quickly, tomorrow he will prepare the materials for making glass mirrors, but he will be busy for a long time.

When he got up early in the morning, Wang Ke washed and played and ran out, and he didn't hear the voice of Nanping calling him behind him, and now Wang Ke's mind is full of what are the raw materials needed to make glass mirrors, and he can't hear anything else, and he can't remember it.

For the process of making lenses, the latest is of course the use of silver mirror reaction to make it, but that can only be done in the later generations, when the chemical industry has been very developed, because to use this method, there must be a lot of chemical reagents that can be obtained through chemical reactions, such as silver nitrate solution, ammonia, sodium hydroxide and glucose solution, these things should be found by Wang Ke now, it is a little difficult for Wang Ke, don't look at Wang Ke will also have a little chemical things, But if he is allowed to start from scratch, he doesn't have that ability.

In the end, Wang Ke still chose a method that seems more realistic now, that is, according to the method of making glass mirrors by Venetian craftsmen, the metal tin is made into tin foil, pasted on the glass, and then the mercury is poured on the tin foil to dissolve the tin into "tin mercury", which is firmly glued to the glass and becomes a mirror.

Although this process takes a little longer, it is also relatively easy to find for the raw materials of this era. Although mercury is toxic, but a small amount of contact, as long as it is not a direct entrance, Wang Ke still knows that there will not be too much of a problem, even if it is to be mass-produced in the future, Wang Ke only needs to teach the workers, tell the workers what needs to be paid attention to in the production process, and do it at all times, there is still nothing to worry about.

Wang Ke hurriedly found Li Ke and told Li Ke what he wanted, but he didn't tell Li Ke what he wanted these things for.

For this matter, Wang Ke has also thought about it, before he made it, but he can't tell anyone casually, one is for confidentiality, and the other is that there are not many people in this flat glass now, if there are more people who know, they will all ask for themselves, especially if Comrade Li Er knows, he will send it to the palace by himself, not to mention that he will use it at home, even if he sends it all to Comrade Li Er, it is not enough, at that time, he will offend a lot of people.

Li Ke was very curious about Wang Ke's mysterious and mysterious behavior, and asked several times tentatively, but he didn't get any useful information from Wang Ke's mouth, although Li Ke was a little unwilling, but he couldn't stand Wang Ke's urging again and again, so he had to let the craftsman make some tin foil according to Wang Ke's requirements.

Wang Ke's original intention was just to make a little bit of flat glass, just be able to make a few pieces of flat glass left in the glass workshop in his village, but he didn't expect the workers to make tin foil, but he brought a lot to himself, Wang Ke unconsciously hesitated and asked Li Ke: "So much, are you still useful here, don't use it when the time comes, but there is no more, then I can't afford this responsibility!" ”

Wang Ke is really afraid that Li Ke's workers here will make all the tin here into tin foil for themselves, now in this era, the output of tin is not much, although it is only used as an additive now, but it can't be not, if he takes it all, once the production is needed, Li Ke has nothing here, then the mistake he made is big, and Comrade Li Er will punish himself if he doesn't get it right.

Li Ke said disapprenorovingly: "How much has it been used, don't think that I don't have it here, all the materials, that is, iron and copper, I need a lot, and I have a lot of others here, and I can't use up the ones allocated every year, so you just have to take it, I don't think there is a place to pile it." ”

As soon as he heard Li Ke's words, he was really happy with Wang Ke, he couldn't find it, Li Ke actually said that he couldn't use it up here, so it was just right, he would 'get' more at a time, so as not to know it in the future, he should pay for it, and now he 'get' it away, but he won't 'spend' the money!

This time, Wang Ke was not polite, and directly asked Li Ke to tell the craftsman how much he could make, how much he wanted, as long as he could pull it away, he would never have too much.

Li Ke saw Wang Ke's excited look, he really couldn't understand what Wang Ke was doing with these things, and couldn't help but ask again: "Brother Wang, what do you want these things to do, I haven't heard that you are thinking about what to do during this time, except for seeing you make a telescope."

Wang Ke's questioning of Li Ke was still resolved by using Tai Chi pushers, only saying that he needed these things urgently now, but where to use them, Wang Ke just didn't say it, and made Li Ke so angry that he really wanted to punch Wang Ke with a few punches.

Wang Ke giggled and Li Ke and then 'inserted' the department and gossiped, and after the craftsman brought all the things, he turned into the car and wanted to drive away, Li Ke was really itching in his heart, just like a cat had been scratching him, and now when he saw Wang Ke leaving, he immediately ran into the car and sat down, letting Wang Ke talk badly, but he didn't come down, and there was no way to 'get' Wang Ke.

Wang Ke had no choice but to say to Li Ke: "It's okay if you want to go, but you have to promise me that no matter what you see, you are not allowed to say it to anyone, even if the emperor asks, you can't say it!" You know? ”

Wang Ke did this thing so mysteriously, and spoke so seriously, which made Li Ke feel that what Wang Ke was going to do now was very interesting, Li Ke now just begged that he could go to see a strange thing with Wang Ke, and of course he nodded and agreed to Wang Ke's request, and promised that he would never say it.

At this point, Wang Ke had no other way, so he had to take Wang Ke to the glass workshop, let the craftsman take a few pieces of flat glass to an empty room and put them away, and led Li Ke to move all the things into the house, and closed the 'door' of the room.

Li Ke saw that Wang Ke was doing such a mysterious, and he was even more curious, urging Wang Ke to hurry up, he really didn't know what Wang Ke was going to do on this glass.

Wang Ke glared at Li Ke with his eyes, took out two handkerchiefs from his pocket, and threw one of them to Li Ke, which was originally prepared by Wang Ke for himself, he was afraid that a handkerchief was not thick enough to stop the volatilization of mercury, so he was sucked into it by himself, thinking that it might be better to use one more handkerchief, but Li Ke could only use one handkerchief.

Li Ke learned from Wang Ke's example and wrapped his mouth and nose with a handkerchief, stood aside and watched Wang Ke make a glass mirror, and at first Wang Ke just tried to 'get', after a while, Wang Ke knew what to do, and soon, Wang Ke made all the glasses, and now Wang Ke is only waiting for these glasses to dry out, and what comes out is not a glass mirror.

This waiting time is not a day or two, and it is useless for Wang Ke to stand here stupidly, so he can only take Li Ke out of the room, come to the glass workshop, and ask a few craftsmen to make some flat glass when they are free, which is useful for himself.

No matter how Li Ke asks, Wang Ke will just say a word, and he will know in a few days, so that Li Ke can't let go of it in his heart, and he is looking at what Wang Ke is doing.
