The success of making soap greatly depends on the concentration of lye. The reason why it is difficult to make it by hand is always that the concentration of alkaline substances is too low.
A dry wooden stick was inserted into the solution, and he carved a knife according to the position where the water was immersed.
Rurik believes that due to the previous high temperature, the potassium nitrate from the plant ash in the solution has all turned into potassium nitrite, so it has become very toxic to the human body, and its toxicity comes from it. of nitrite. As long as this nitrite root comes into contact with fat, it can turn into alkaline but harmless soap.
Even if he doesn't know the specifics of the solution, if he continues to boil it, two-thirds of the water in the urn will be evaporated, and the remainder will definitely be a highly concentrated solution.
What’s more, a large amount of crystals will precipitate in the clay urn as the urn continues to cool.
As long as the water in the urn is lost until only one third of the length of the stick is left at the water immersion point, it is enough.
So, a fire in the chief priest's house became Rurik's testing ground, and he himself gloriously announced to all the priests that the greatest action is now.
This glorious declaration is not important. Feeling that it was already very late, High Priest Vilya, who was already planning to go to bed, walked up to Rurik on crutches and witnessed everything he was going to do. .
Rurik received the attention of all the priests, but now it seems that the child is just boiling a jar of brown-yellow water with a special smell.
Because there are many impurities in the water, which are not the key substances for making soap, they exude the unique burnt smell of charcoal. The smell reaches the priest's nostrils, proving that the water and charcoal have special characteristics. origin.
The water is boiling, and a large amount of steam begins to spread indoors. It quickly seeps out into nature along the cracks in the house.
The longhouse of the priests has a lot of gaps and no special chimney. The people inside never consider whether lighting a bonfire indoors will cause poisoning.
No one has the concept of carbon monoxide poisoning. It is because of the flaws in the houses they built. The large number of gaps unintentionally caused the heat to be lost quickly, forcing them to frequently light charcoal fires in winter, and there was no reason for this. Poisoned.
So the odor emitted by the boiled solution gradually dissipated, and only the inside of the brown pottery urn was visible. The water line receded at a speed that was almost visible to the naked eye, leaving cleaning marks on the urn wall.
The current solution is very dangerous, not only because it exists at a high temperature of 100 degrees, but also because its alkalinity is rapidly increasing. If the potassium nitrite inside turns into pure crystals, it will be extremely dangerous. Alkaline substances can quickly corrode the skin and flesh that come into contact with it.
But when crystallized and mixed with other substances, it is the key to a new era of human melee.
The priests who were watching wanted to see something newer. After staring for a while, they realized that they were just filling water, and gradually lost interest.
It was getting very late after all, and some people didn’t want to spend any more time here, so some people went back to their sleeping quarters and closed their eyes..
Rurik's work has really just begun. In order to get the soil soap out as early as possible, he must have made a decision in his heart. He will have to work until dawn, or his own The spirit collapsed from excessive exhaustion.
The water level in the urn continued to drop. When the lower-level priests left one after another, Rurik was only accompanied by the loyal Lumia. Not far away from the two of them, there was Vilia who was waiting for a result. She continued to sit cross-legged on her soft leather cushion and take a nap with her eyes closed.
Rurik didn’t want to disturb those people. He worked seriously, but he was disturbed by uninvited guests.
The time was actually very late. According to the past, he should have gone back to his home to sleep.
The son has been staying in the longhouse of the priests. Today, the son is still clamoring to make some new invention, a treasure that can be easily washed. Otto did not interfere with his son's plan at all. His son had not come back until late at night, and the heart of an old father couldn't help but worry.
Otto hurriedly broke in to see the priest, waking up many sleeping people and causing Viglia to raise his head suddenly from his nap.
"My leader! You! You shouldn't rush in in such a hurry, what are you going to do?!"
"I..." Otto looked around anxiously. Two young figures were busy around a campfire, and his anxious heart calmed down.
"Ah, great priest, I'm just here to take Rurik home to sleep."
"He's right there, don't worry." After that, Vilia Just point.
There was a strange smell in the air, and Otto's nose was very keen to smell this abnormality. A strange smell came from his son, and the pottery urn that the two children were playing with, along with his son's servants, caught his attention.
"Rurik, what are you doing?"
"I know you are coming, Dad." Rurik said perfunctorily.
"Is this the pottery urn? You said you wanted to make something special, have you achieved any results?"
"This is it." Rurik was very proud and thought I want to introduce Otto Haosheng. But then I thought about it, the lengthy description was just nonsense, and the last word is to show the real thing.
Rurik thought for a while and muttered: "I won't go back today, I want to do a great thing. Dad, go back and tell your mother that I will definitely take out the My invention."
But Otto could hear that his son was announcing that he would stay up all night.
"Ah? My child, you are not a hunter yet, so you don't need to stay up all night. You are too young. I believe you will succeed. It is better for me to take you back to sleep now."
"No! My work has reached a critical moment." Rurik raised his voice.
"Perhaps, you can leave the work to your servants. Listen, this is what servants are made for." As he said this, Otto winked at the ignorant Rumia.
Otto’s idea in exchange for Rurik of coursesternly refused.
He thought to himself, as an old guy with a mental age of forty years old, I have had enough trouble pretending to be a seven-year-old child and pretending to be innocent. Do the so-called adults have to forcibly deprive a child of the right to play with toys? .
Ah, this toy is made of extremely dangerous lye...is it considered a toy?
No, Rumia doesn’t understand anything at all. She will help me do many things in the future, but only if I teach her the first time.
Rurik stamped his foot, "Dad, you must believe me this time, you will gain huge wealth because of your correct choice tonight."
"Wealth? Me My child, you are my greatest asset." Otto knelt down, his eyes converged, and he pinched his son's soft face as if coaxing a child, "You are only seven years old, of course you will have to experience real life in the future. It’s time for you to go to bed.”
“No! I will never be a man who only knows how to row a boat and fight. I also want to be a wise man!” Zhongryurik pointed to his brain, "I want to use my strength to become a leader, and I want to use my brain to make everyone rich. Dad, you must listen to my opinion. Don't you believe in your son? Or you... you Do you think I'm the same as other children?"
Otto was calmed by questioning about the depths of his soul.
Ask yourself, when this child is holding his own "Destroyer" sword in the snow in the background light, protecting his current servant, this child is really no different from other little boys. Same.
At that moment, Rurik was no longer a child at all, as if he was possessed by some great being.
Seeing that his son is so stubborn, he is afraid that he will run away like a lamb by force, and the child cannot sleep peacefully on the soft leather blanket.
Otto said no more and left angrily.
The dispute ended and the huge room became quiet again.
Villa could once again close her eyes with peace of mind, knowing that no one would disturb her clear dream tonight. She was also curious about Rurik's invention. After listening to the child's simple description, the invention was a mixture of seal oil and yellow water in an urn. Before Rurik explained, no one in the tribe had tried this.
Even the priest who often boiled oil, and even his younger self, did not have such a whim. Perhaps, the convergence of the two will indeed produce a miracle, but that will not give the elderly Vilia greater mental stimulation. She is too old, and her appetite for novelty has diminished.
Villa returned to her compartment, lay down on the sleeping nest made of animal skins, and soon fell asleep.
The hall of the priest's longhouse suddenly became empty. Rurik looked at the quiet scene around him and couldn't help comforting Rumia who couldn't help but yawn.
"Ah, we are the only two left now."
"Rurik, you? Continue?"
"Yes, next I will needWant your help. My sister, you and I don’t have to rest tonight, because I promised my father that I will produce results. ”
Rumia understood the meaning. She did not refuse, and she had no right to refuse. She could only obey the master’s order with all her strength.
This was not an difficult order to accept. , it's even full of fun.
Now, the roasted pottery urn rests, and the hot solution inside is gradually cooling down. Rurik still doesn't know the concentration of potassium nitrite in the solution. The water immersion position has reached the target value, and its concentration must be sufficient. He believes that the saponification reaction can start as long as it reaches a critical value. The only problem afterwards is that the concentration of the solution determines the hardness of the soap.
In fact, it remains. This is also the first time for Rick to make earthen soap. The principle is so simple. Making exquisite soap, and even making soap with exquisite fragrance and charming fragrance, is his ultimate desire in this regard.
< p>Because as long as it succeeds, people in the tribe will use it to clean their bodies, and the fragrance will replace the inherent sweat odor and even bad body odor. Especially those who are willing to dress up their appearance, they will pay huge sums of money to buy one. A soap that is both clean and fragrant.Rumia hung the pottery jar filled with seal oil over the bonfire. Gradually, the semi-solidified oil gradually turned into a pure liquid state.
"Is this okay? Need more heat? "She asked Rurik.
Rurik stretched out his little hand and tentatively touched the liquefied grease. A strong pain felt on his hand.
"That's enough. If It makes our work harder. ”
The saponification reaction requires a suitable temperature, and there is no doubt that the boiling oil is simply overheated.
He asked Lumia to heat the oil again, and then ordered her to heat the pottery urn Move down.
“Rumia, the most important thing is now, you can avoid it for now. "
"Why? I will help you well. ”
“No. You observe my movements for now, you have to remember my movements, and you have to do these things yourself in the future. ”
“I will. "
Rumia walked to the side with an uneasy heart. She still stared at Rurik's movements.
There is a saying that if there is more oil, add more water and more water. If Knowing the exact concentration of the key substances in the solution, as well as the exact mass of all materials, Rurik can master the blending ratio of all substances in advance with some mathematical calculations. Now he has no choice but to use a very stupid method, which is to use. Use a wooden spoon to pour the hot liquid oil directly into the plant ash precipitate of unknown concentration.
Pour in the first spoonful of oil, and the saponification reaction will occur instantly.
Clear and light yellow oil. The color suddenly changed, and there were still a few tiny bubbles.
He continued to pour the oil, and finally poured all the oil in the pottery jar.
But it was oil and water. Naturally repellent, grease is only specific to alkaline substances dissolved in waterinterested.
"Ah, that's great. If I pour the oil slowly, there won't be a violent chemical reaction. Next..." Rurik paused for breath and observed Luo carefully with a satisfied smile. Mia waved, "Come here, your work is next."
Rumia is now a servant. If she has a lot of time to spare, she will definitely attract criticism from others.
Rurik does need such a sister to do a lot of things. She is ten years old and she is only seven years old. Of course, her mental age is completely different. A seven-year-old child is holding a wooden stick and frantically stirring the grease and water. The mixture, even if it is quite strong, will tire out after a while.
"Rumia, take a wooden stick, and then you will stir this pottery urn. This will be a tiring process, and you must do this in order to make a treasure."
< p>Afraid that she might not understand the Norse language well, Rurik explained slowly, and then explained the key words in the newly learned ancient Sami language."I will work hard to stir, and I will make you happy."
Rumia has no complaints and can do great things for her "brother". For the honor of being a servant, otherwise Sister Sheng would really deserve it.
She stirred the material in the pottery urn with a selfless and heroic attitude. Soon, the changes in the material exceeded her cognition.
The saponification reaction has fully begun. Rurik cocked his head and watched the chemical changes taking place with satisfaction.
The light yellow and quite transparent oil has changed its nature, and it is becoming as viscous as butter. Because of the color of the plant ash precipitate, the mixture in the urn turned into a brownish-yellow paste, accompanied by a special smell, just like normal soap.
The permeating smell was exactly what Rurik wanted to smell.
He was so excited that he used plant ash and seal oil to create soap in ancient Northern Europe thousands of years ago.
He was very sure that the substance in the urn was soap, but the dissolved alkaline substance was rapidly combining with fatty acid molecules due to Rumia's selfless stirring.
A large amount of water needs to be eliminated, but it should not be eliminated completely.
Soap can be as hard as bricks in the sun, and the water content in it can be very low. Even such soap feels terrible when used.
Of course, too much water is not good. The soap bar is too soft and has relatively few active ingredients, so it will not be durable.
The soap base liquid has been completed, but it is still very hot. Even if Rumia's arm is already very sore, the heat of the paste can instantly burn the skin and flesh that comes into contact with it.
"Rumia, are you tired?"
"No! I can still persist."
In fact, she must be very tired, this ten The 20-year-old girl's forehead was already covered with sweat, and the movements of her hands slowed down.
"Stir slowly now." Rurik patted her on the shoulder, but the girl took it as an encouragement, so he gritted his teeth and stirred hard.
"There's really nothing we can do about you. Okay, so you won't be able to go grazing tomorrow because you're too exhausted. That's fine. I'll have to entrust you with a big job in the future. It's enough to let others do the grazing for you." After muttering, Rurik went to get the small wooden box he had prepared in advance.
