Kaimer Strell had hardly slept in the past few days, and he found that coming to Border Town was the most correct choice he had made in his life.
It took two days and one night to read through "Elementary Chemistry", and after two or three hours of sleep, I was full of energy again. Now that he has returned to the first page, he has carefully studied this ancient book.
Matter is made up of tiny particles! The change of matter is the disintegration and reorganization of particles! During the reaction, the total amount of matter remains the same!
God, what kind of person is the author of this book, who can describe the world that people can't see so clearly. He had more than once suspected that the contents of the book were made up, but according to the above example, alchemy experiments were carried out, and the results were completely consistent! Moreover, some common examples in reality can also prove the correctness of the certificate.
For example "Oxygen" described in Chapter 1.
This gas is the main component of air, and what people breathe is not air, but oxygen. Oxygen is required for flame combustion because combustion is essentially an oxidation reaction. The more oxygen, the more vigorous the combustion.
These words reminded him of the glass kiln in Chishui City. It took two people to keep shaking the blast bag to raise the temperature in the furnace to the melting point of sand and stone. Since it is a substance, obviously it can also be alchemy... No, pure oxygen can be extracted through chemical reactions. If you can directly pass oxygen into the furnace, can you save the blower equipment
And the most amazing thing is that the book says that water is actually composed of two hydrogen particles and one oxygen particle, which is probably why all living beings drink water. However, hydrogen seems to be a gas, and the two gases together become a liquid. How is this done
Kemmer found himself with many questions to ponder. But there is no doubt that he has walked in front of all alchemists. When they were still groping for the formula in chaos and fog, a straight and flat road appeared in front of him.
However, business still has to be done. He reluctantly closed the book. At this time, the sky was getting white, and it was time to work again.
Kaimo blew out the candle, approached the bedroom, glanced at his sleeping wife and daughter, and went out quietly.
The house assigned to him by His Royal Highness is located to the west of the castle, which is much larger than his home in Chishui City. Kitchen utensils are readily available. Although he didn't say anything, he felt more satisfied in his heart. The disciples lived in another community two blocks away from him. The house was a little smaller, and it was not a single house. It was a bit like a hotel layout, and one bedroom could accommodate four people.
When they walked to the chemical laboratory by the Chishui River, the disciples were already busy. They were handpicked by Kemo, who had been taught cleaning materials at the alchemy workshop almost as children, and are now in their twenties and thirties. Seeing the neatly cleaned laboratory and the shiny glass containers, Kaimer nodded with satisfaction.
"Good morning, Chief Instructor," the disciples bowed their heads and saluted together.
"Let's start." He took out a pair of gloves from the cupboard and put them on—the gloves were extremely thin and flexible, probably made of animal intestines stitched together. The alchemy workshop had never had such a regulation before, but His Royal Highness repeatedly emphasized the danger of chemical experiments. In the operating regulations, anyone involved in the reaction of corrosive raw materials must wear gloves and open all windows at the same time.
Unlike the workshop, their job content is now very clear, that is, to make acid for His Royal Highness. They have operated the method of making acid with two stones many times, so Kaimo only needs to patrol and give pointers, and he does not have to end up doing it himself.
These two acids are described in detail in "Elementary Chemistry", one is called sulfuric acid and the other is called nitric acid. And he used to use the product to name, for example, the former is called chlorovanic acid, and the latter is called nitrifying acid. The names are different, and the preparation methods are basically the same. The acid vapor is obtained by dry distillation of chloralite and saltpeter, and then the acid liquid is collected by condensation. Green vitriol is usually associated with sulfur ore, and saltpeter is produced in special nitrile ponds in big cities, both of which are common raw materials.
However, His Royal Highness emphasized that the concentration of the two acids he wanted must be high, and he specially explained the purification method.
For example, after the sulfuric acid is collected, the water can be evaporated by heating, and finally concentrated sulfuric acid with a concentration of 98% can be obtained. However, nitric acid is a lot of trouble. According to His Royal Highness, the acid itself is not stable and easily volatile. When the concentration reaches a certain level, it will decompose even when exposed to light. Therefore, the dilute nitric acid obtained by dry distillation must be mixed with concentrated sulfuric acid and heated, so that the concentrated sulfuric acid absorbs water, evaporates the nitric acid, and stores it in a brown glass bottle. To this end, His Highness also specially prepared a thermometer.
The first time Kaimo saw it, he felt that this thing was really ingenious. A hollow glass tube contained mercury, and both ends were sealed, so there was no need to worry about mercury leakage. There are several lacquer lines drawn on it, and the mercury will gradually rise when heated, and the final position will represent the current temperature.
Today, the laboratory has produced three bottles of concentrated sulfuric acid and one bottle of concentrated nitric acid. At this concentration, he discovered that sulfuric acid is not as easy to flow as water, but more like some viscous oil. Nitric acid is no longer colorless and transparent at high concentrations, but turns light yellow. As long as the cap of the glass bottle is opened, bursts of white smoke will be emitted.
"Master Teacher, do we have to make these two kinds of acids every day?" asked a disciple named Amon.
"Until His Highness explained the new task." Kemo paused, "What's the matter, worried that there is no time to explore the alchemy formula?"
Amon nodded.
Kaimo touched the beard on his chin and smiled, "Forgot to tell you, the title of alchemist is no longer needed, so you don't have to rely on the formula to become an alchemist."
"No..." Amon was stunned, "I don't need it anymore?" The other disciples also slowed down their work and listened to what the teacher wanted next.
"That's right, alchemy formulas don't need to be explored, but memorized and derived," Kaimo clapped his hands and gathered everyone around him, "His Royal Highness gave me a copy of Elementary Chemistry - this is what I brought with me. The reason for your coming here, if you study thoroughly, most of the formulas in the world can be inferred from the content of the book."
"Speculate?" The disciples let out a low cry.
"That's right. After I read it in detail, I will teach you a class." He said, "As for the promotion path, His Highness also mentioned to me. In the future, you must pass the test arranged by him in order to obtain the title of chemist. I believe I, it won't be long before this honorary title will completely surpass that of an alchemist. And the knowledge you possess is beyond the reach of even the Royal Alchemy Association."
