"General, that's the pyrite found in this area.
One of the guards circled his arms toward a large area.
"Please, Princess" Yang Yan arched his hand to the dozen or so old craftsmen.
"The general is gracious."
The old craftsmen didn't even dare to say it, and then scattered everywhere to find the source of the minerals.
It took three days to excavate the iron cap, and the iron cap was mined along it, and sure enough, it was pyrite.
Yang Yan was overjoyed, and took people to find diatomaceous earth, which is a very extensive sedimentary rock, distributed in large quantities along the central and eastern coasts of China, composed of the remains of diatoms in ancient times, the main components are silica and opal, which is very easy to find.
By the time he returned, a pile of pyrite had been mined.
According to Yang Yan's design, the craftsmen erected a brick cellar, square, one zhang long and one zhang wide, with a flue at the top and bottom, and the one on top led to a small pool.
Cui Ling couldn't help asking: "General, what is this?"
Yang Yan smiled mysteriously: "This is called the combustion chamber, you look at it, and you may not be able to understand it." ” "Hmph" Cui Ling snorted.
Yang Yan ignored her, turned his head and called: "Come on, take a part of the pyrite and put it on the upper layer, and put the diatomaceous earth in layers near the flue sieve hole, to be even, not too tight, to ensure that the smoke passes, and the bottom is cultivated with charcoal." ” "No" The craftsmen were busy for a while, and arranged them according to Yang Yan's requirements.
Through the vents, it can be seen that gradually, yellow-green smoke rises from the combustion chamber, and since the upper level of the combustion chamber is almost airtight, the smoke can only overflow into the pool along the upper flue.
Everyone is full of puzzlement, you look at me, I look at you, big eyes and small eyes.
Cui Ling still couldn't help but say: "General, don't look down on people, although the concubine knows that you know some inexplicable things, but others may not understand." ” "That's good" Yang Yan nodded, and said: "Roasting pyrite can produce sulfur dioxide, and diatomaceous earth contains potassium nitrate and garlic, which reacts with sulfur dioxide to form sulfur trioxide, and then injects sulfur trioxide into water to produce sulfuric acid, which can be understood."
Cui Ling showed a look of indignation, opened her eyes and looked at the pool, but finally snorted, obviously not understanding.
Others feel the same way.
Yang Yan smiled: "When I make up the heavenly creations, you will understand." ” "Hmph and pretend to be a ghost again" Cui Ling's chest rose and fell for a while, and she swallowed a sullen breath.
Yang Yan glanced at it casually, and then continued to look at the combustion chamber.
About half an hour later, wisps of thin gas began to emerge from the water surface, and the water was much thicker than before, which was a sign that the concentration of sulfuric acid had reached the limit, and it should belong to the level of oleum sulfuric acid, so Yang Yan called a stop.
The old craftsmen extinguished the charcoal fire, Xun Hu also touched his head, and asked, "General, this is sulfuric acid, I think it is similar to Qingshui" As he spoke, he was about to put his hand in.
"Slow" Yang Yan hurriedly shouted, and Xun Hu was frightened and froze on the spot.
Yang Yan shook his head and said: "This thing is ten likely to be concentrated sulfuric acid, put your hand in, I see that your hand is not wanted, come on, find a piece of meat, and pour some on it." “ "No Several guards should be lowered.
In the wilderness, meat is not easy to find, but it doesn't matter, someone opened a bow and an arrow, and shot down a wild goose with an arrow, and someone scooped out a spoonful of sulfuric acid with a wooden spoon, the spoon was immediately scorched, and the person's hand shook and dropped a few drops on the body of the wild goose.
Suddenly, there was a loud sound, a burst of white smoke rose out of the air, and as soon as the man's frightened hand was released, a large spoonful of sulfuric acid was splashed, and even more intense white smoke came out, and the area was as if it had been burned by fire, and a large piece of skin and flesh was rotten.
Xun Hu was covered with cold sweat on his forehead in an instant, and he looked at his hands fearfully.
"Xunhu, the poison of sulfuric acid is worse than arsenic, and the sex is violent, so you can touch it casually, otherwise you won't blame me for not reminding me in advance if I lack arms and legs in the future."
Yang Yan smiled pitifully.
Xun Hu sneered.
Yang Yan instructed again: "But this is not the most poisonous thing, on top of the sulfuric acid, there is still nitric acid, come, take a wooden spoon and scoop some sulfuric acid into the clay pot, about half an inch high, put it into the nitrate."
"No" After seeing the power of concentrated sulfuric acid, no one dared not take it seriously, an old craftsman carefully did as instructed, when the wooden spoon reached into the sulfuric acid pool, the head was sweating, and then the nitrate was sprinkled into the sulfuric acid, and there was an incredible phenomenon, accompanied by bursts of bubbles gushing out, the nitrate dissolved at a very fast speed, and at the bottom of the clay pot, there was a layer of white solid gradually thickened.
The reaction lasted for a short time, not long ago, the tank has returned to calm, the liquid is still clear and transparent, except that the nitrate has become a layer of white solid, the principle of which is very simple, the main ingredient of nitrate is sodium nitrate, which reacts with concentrated sulfuric acid to generate sodium sulfate, which replaces nitric acid.
Looking closely, there seems to be no change from before, everyone's faces are intertwined with doubts, and Cui Ling's beautiful eyes are even scanning back and forth on Yang Yan's body.
In fact, Yang Yan's method of making nitric acid is not economical, but also seriously wasteful, the mainstream method of modern society is to mix ammonia and air in a ratio of two to one, pass through the hot platinum network, generate nitrogen dioxide, and directly connect to water to produce nitric acid.
This method is not impossible to do under the conditions at that time, sulfuric acid is the basis of modern industry, the production of sulfuric acid, almost through chemical reactions, a series of chemical raw materials, take ammonia as an example, ammonia can be made through sulfuric acid, platinum net can also be made at a high cost, Yang Yan to the most primitive method to make nitric acid, mainly eye-opening.
With 120,000 satisfaction, Yang Yan said: "The jar is nitric acid, the pool is sulfuric acid, the difference between the two, in the future I will explain it separately in the book of Tiangong Kaiwu, now I will let us see miracles and take some silk wool." ” Cui Ling pulled out a small piece of silk wool from the casual package, and Yang Yan took some concentrated sulfuric acid and nitric acid to mix in proportion, and then took the silk wool, and in the shade, tore off a small handful and soaked it in the mixture, with gentle movements and a dignified face.
You know, this is nitrocellulose, if you are not careful, not to mention the end of your life, it is indispensable to blow up your face and disfigure.
Seeing that Yang Yan was so nervous, Cui Ling asked, "General, what are you doing?"
"What are you anxious about, you'll know later, stand far away, all lie down" Yang Yan waved his hand impatiently.
"Hmph" Cui Ling snorted, secretly angry, but she couldn't hold back her curiosity and retreated far away with everyone.
Yang Yan put the nitrocellulose fiber on the ground, put a wooden shelf on it, erected a piece of slate, and then picked up a dry stone from the sun, retreated to Cui Ling's side, took a slight aim, threw it out of his hand, and then fell down violently "Boom" The moment the stone hit the cotton wool, the flames soared into the sky, the wooden shelf shattered and burst into the air, the stone slab was scattered and cracked, the stone fragments flew over the top of the head, and even people's hair was rubbed.
"Ahh Cui Ling screamed in fright and couldn't help hugging Yang Yan.
"Don't be afraid, don't be afraid" Yang Yan hugged Cui Ling with his backhand.
"Ahh It's not just Cui Ling, many people with slightly worse mental quality are pulling their necks and roaring, what Taishan collapsed in front of and the color remains the same, and the real landslide and ground crack are not so scary.
The explosion came and went quickly, everyone was pale, their eyes were straight, looking at the explosion scene in front of them, this was probably the first explosion that people saw at that time, and no one could have imagined that a small piece of silk wool would actually become a killer Stunned Even Cui Ling was hugged by Yang Yan and forgot to break free.

Yang Yan is a little excited, nitrocellulose, is the basis of smokeless gunpowder, the explosive power is 100 times that of ordinary gunpowder, although the nature is violent, a touch will be exploded, but as long as the silk wool is dried and mixed with an appropriate amount of diatomaceous earth, it can be made into a stable explosive.
It can't be fried, thrown or fried, and it can't be burned or fried, and it can only be detonated with thunder, garlic, and mercury.
The manufacturing principle of mercury is also very simple, it can be obtained by mixing concentrated nitric acid and anhydrous alcohol to react, which is the so-called primer, and then slightly packaged, it is Lei Guan.
With Lei Guan, the simplest grenades can be made, and artillery can also be cast, which is much more powerful than the black fire kiln, which is equivalent to stepping into the late nineteenth century, in that era, smokeless gunpowder really matured, replacing the black fire kiln appeared on the battlefield, and because of the emergence of smokeless gunpowder, it made machine guns possible.
Of course, it is more difficult to develop firearms than artillery, and Yang Yan does not have the luxury of getting guns out for the time being, and if smokeless gunpowder technology wants to mature, it is also a long process of tempering.
If nothing else, let's just say that the premise of synthesis is to make liquor, and it is necessary to make highly distilled liquor
