"That's good, you can work your own." I nodded in satisfaction, and at this moment, I could already see the buildings hidden at the foot of the mountain in the distance, and finally arrived.

"Your Majesty, look at these, this is the mirror that left the factory this time, but the yield is still not enough, at most it is close to thirty percent." The head of the workshop, Sun Zhongsheng, stood next to me and pointed to the glass mirror in front of him, which was less than fifty pieces in the warehouse. "The other seventy percent are more or less flawed in one way or another."

"There are so many defective products?" Ben Gongzi couldn't help but sigh lightly, but compared with the previous one and a half percent, the yield has doubled, which is already quite good......

"No way, the area of the glass is too large, and you can't squeeze it hard, it's difficult to make the tin foil stick to the glass, and the last thing is the way that an old craftsman came up with, put a thick cloth under the glass, and then put the flour dough on the tin foil, and roll it with a rolling pin, and finally let the success rate reach 30%."

Hearing this, I couldn't help but nod. Indeed, it seems that I am too anxious, and the reason why I want to get such a big mirror is naturally to enjoy it myself, decorate my bedroom and inlay it, and then start selling. You can't let my bedroom be inlaid with thousands of small mirrors, right? That day, I knew when the road would be completed, so I simply asked these people to make the mirror bigger.

It seems that it is indeed very difficult to eat a big fat man, but I really didn't expect that those old craftsmen would be able to think of such a local method.

"Pass on the order of this son, and the old craftsman who came up with this method will be rewarded with five hundred yuan. If there is a way to improve the yield next time, as long as the method is proven to be effective, I will not be stingy with the reward. ”

The old craftsman who came up with the idea came to thank him with an excited face, and after comforting the old craftsman, I was actually very satisfied.

I remember the history of glass mirrors that I once saw in later generations, and the price of a small palm-sized glass mirror could reach 150,000 francs. That is, at least today, it is equivalent to 3 to 50,000 guan.

In any case, those defective products, if they are thrown out, will definitely be regarded by the world as heirlooms, worth 10,000 gold.

I asked someone to take a glass mirror and put it in front of me to take a closer look, indeed, the yield of this ancient method of mirror-making is indeed much lower than that of the industrial production of later generations, but it is already a remarkable achievement to be able to make such a clear mirror.

I also asked the workers if they strictly followed the operating procedures, and when they entered the production workshop, they strictly followed my requirements, wearing masks stuffed with fine carbon and windproof glasses.

"Your Majesty, don't worry, these people are all old people in the house, who dares not to listen to your words? Besides, you're also looking out for their safety. The person in charge of the workshop replied with a serious face.

"Well, that's good, by the way, these glass mirrors will be sent to the villa early tomorrow morning, install them quickly, my son can only have a bedroom." Don't you want to have to rest in other rooms in the middle of the night? ”

"Don't worry, at most, you can paste all the fifty glass mirrors." The person in charge of the workshop is full of confidence.

"That's for the best. In addition, where are the defective products, take me to see. I nodded in satisfaction. These mirrors, if my bedroom is pasted, it is equivalent to millions of dollars, tsk, tsk, I am afraid that it is the mirror palace of Versailles, and there is no bedroom cow fork of my son.

After a short period of effort, I came to another warehouse, where there were a lot of glass mirrors, but each mirror had more or less flaws. Even some mirrors, although they do not have too many flaws, have a little deformation of the human face, which is naturally impossible to want.

"Of these thirty or so pieces, each of you will carefully pick out the usable parts, and then cut them, and when the time comes, use gold to edge them...... "Although these mirrors have many flaws, there are also many places where they can be used.

"Yellow, gold to inlay?" The person in charge of the workshop had wide eyes, and he couldn't speak properly.

"Nonsense, let you use gold for inlay. As for you, according to the situation,...... Circles, squares, rectangles, and even polygons can be, but they can't be bigger than the size of a palm, you know? "I put the glass mirror with at least four or five wrinkles back to its original, just this mirror, at least ten mirrors the size of a palm can be cut, and when the time comes, after the gold inlay, if it doesn't sell for thirty or fifty thousand yuan, isn't it sorry for the ingenuity of this son?

After reading this, I walked to the workshop on the other side, where the glass with high purity is being polished, and most of these polished glass products will be used to make telescopes, and only a small amount will be used to make microscopes.

After all, the use of microscopes for military purposes is much larger, and microscopes currently only serve a role in medicine. For example, Sun Simiao's old man, it is difficult to go out almost once a month, and he is often specializing in the various medical devices given to him by his son, and he also wrote down the use methods and specifications of each medical device and compiled it into a book.

It can be seen that Sun Simiao is really dedicated, at least I can't have his passion for doing a line of love and death.

Not only these two, but also beakers, glass tubes, in short, all kinds of cups and tubes that need to be used in chemistry, are available here, and even a lot of large bottles are made, which are naturally used in sulfuric acid plants.

Today, the production of sulfuric acid is much higher than it was at the beginning. However, its main role at present is still to conduct tests in the laboratory, and at present, 80% of the staff in the laboratory are Taoist priests, and the other 20% are specially selected students with strong loyalty and strong interest in science and technology.

At present, the use of sulfuric acid passivation treatment of the plate armor, after a year of testing, so far, still no traces of rust or rust points have been found, and ordinary plate armor, in less than half a year, has appeared in the rust point, such a result, so that the son, but also let all the staff of the sulfuric acid research laboratory happy, after all, such passivation can be used on a large scale, then, in the future, just the maintenance and maintenance of the plate armor and the replacement of rusted plate armor, I don't know how much money I can save.

At present, those researchers with greater fighting spirit and enthusiasm, into the new research, sulfuric acid this thing is very versatile, coupled with the mention of this son, I believe that in the near future, they will be able to study nitric acid, at that time, nitroglycerin, ammonium nitrate and many other practical products, will appear in people's eyes, life.

In my opinion, the preparation of nitric acid is simpler than that of sulfuric acid, and it only needs to be prepared in a laboratory, using sulfuric acid and sodium nitrate to generate nitric acid and sodium bisulfate. Doesn't nitric acid come out? As for sodium bisulfate, I don't really know what this thing is best used for, but they'll have to test it themselves.

As for getting breech guns, it is no longer a dream, because with nitric acid, it is possible to make not only smokeless gunpowder, but also the primer of breech guns.

After inspecting the research institute of his own family, he naturally wanted to inspect the country's weapons and equipment manufacturing plants and weapons research institutes for the sake of the country and the people.

Swords and other things are also produced here, but they are only produced as experiments, and the researchers here are not trying to make money for the sake of production, but are trying to study how to make weapons sharper, and at the same time more elastic and endurable.

In addition, he is also specializing in the production of artillery and muskets, but it is currently in experimental production. It was here that I saw the artillery hydraulic station-and-retreat device, which had been made.

This anti-recoil device was used on the gun, and by connecting it to the gun body, this gun mount became an elastic gun mount. When firing, the gun body recoil relative to the gun carriage, and the whole gun does not move back. The anti-recoil device consumes most of the recoil energy, and the force on the gun carriage is greatly reduced, thus greatly reducing the mass of the whole gun, and at the same time increasing the firing speed.

In this way, the breech gun can also be lightened. After asking those researchers, it was learned that at present, five types of hydraulic stationary machines of different sizes have been produced, and according to the size of the gun body, it should be able to meet the bearing of the gun body from 60 mm to 120 mm caliber.

The 60 mm caliber is equivalent to the six-pounder cannon of the Age of Discovery, and the 120 mm caliber can fire 35 pounds of ammunition.

And in the Western Age of Discovery, the caliber of twelve-pound guns reached one hundred and twenty millimeters, why? Naturally, because of the different shapes of the bullets, the conical shells that this son wanted to use were naturally conical shells, not iron projectiles of that era

Of course, this is just a theoretical data, after all, the design of today's artillery body is still in the process of improvement, and the gun body is currently being tested and produced using cast iron and bronze, which is not to say that it is finished as soon as it is cast, but it needs to be studied many times, what caliber of the gun body is most suitable for the lethality and weight of the gun body, and what kind of double diameter can obtain a good firing range, and what kind of method can make the inner wall of the barrel of the gun more smooth and heat-resistant and corrosion-resistant. What kind of method can be used to make the barrel of the same thickness stronger and more durable?

In short, all kinds of extremely difficult tests are in preparation for making better artillery. I don't want to make any more so-called firearms that can't take the nomadic cavalry, which can only be regarded as the germ of the firearms age. What I want to do is to ensure that the Chinese Empire, an agrarian civilization, can eliminate the threat of nomadic civilization to the Chinese Empire in the shortest possible time.

In a word: science and technology can not only strengthen the country, but also save the country.
