Mr. Zhao actually deliberately challenged the so-called taboo.
The moment he set foot in this four-legged village, he could feel countless pairs of eyes staring directly at him in the low thatched huts.
Mr. Zhao didn¡¯t care. He walked to the sulfur-making shed at the end of the village with a relaxed expression. A dozen untouchables who were busy inside quickly knelt on the ground in fear. They were only ordered not to go out today, but they were not told not to work in the house.
Zhao Hao ignored them. His eyes were attracted by the baskets of yellow things in the shed.
"Is this the sulfur ore transported from the volcano?" Mr. Zhao asked.
The Tang Dynasty Interpreter hurriedly translated, and the leading untouchable nodded timidly.
"Ask him, what should we do next?" Mr. Zhao said to the interpreter.
The interpreter hurriedly translated and urged a few more times before the untouchable stood up in fear. However, he saw the Tanegashima gentleman standing outside with a tangled look on his face. He was so frightened that he quickly knelt on the ground.
Zhao Hao looked back and said displeasedly: "Why are you following me here? Kneel down outside."
Tanegashima Shiyao and others still hesitated to kneel down. It's not that they are unruly again, but this is a village of untouchables. How dirty!
The guards wearing black leather boots kicked each of them in the back, knocking them to their knees. These guys just knelt on the ground.
"They are kneeling down, you stand up." Zhao Hao said to the old man: "This is an order."
The old man quickly stood up obediently, bowed his waist and led them inside while introducing the process of making sulfur. It is nothing more than using a sieve to remove impurities, then crushing the sulfur ore with a roller, and grinding it into sulfur powder with a small mill. Then add five or six bowls of water to thirty or forty pounds of sulfur powder and boil it in a large pot. The smell of rotten eggs soon filled the air.
"Hydrogen sulfide, wear a mask." Zhao Hao covered his nose.
Hearing this, Secretary Ma quickly pulled out a black cotton mask like a magic trick and put it on Mr. Zhao. I also wore a blue one.
Wang Rulong and others also quickly took out their masks and put them on, which Mr. Zhao ordered them to wear before he came.
Zhao Hao explained to everyone in a muffled voice that boiling in water is to remove impurities such as acid and ash powder in the sulfur powder. During the heating process, a large amount of water is evaporated together with the acid. When the water evaporates, the acid is removed. Then the temperature in the pot can continue to rise to the melting point of sulfur.
I saw several untouchables lift the iron pot, pour the melted sulfur into a coarse porcelain basin, and wait for it to cool slowly.
Because the specific gravity of ash is higher than that of sulfur, it sinks to the bottom, so the higher you go up, the higher the purity of the sulfur. The top part is called the 'yellow tip', which is very pure in color and is the finest material used to make black gunpowder.
The remaining base needs to be boiled again to extract more sulfur powder. In this way, about five kilograms of ore can produce one kilogram of 'Huang Shao', which is more than ten times more efficient than using sulfide to make sulfur.
"Okay, very good." Zhao Hao opened a jar of the cornmeal-like sulfur powder they made and couldn't help but praise it. I have to admit that the Japanese are serious and meticulous in their work. The sulfur powder they prepare is visibly purer than that of Ming Dynasty.
"Take it back to mix with gunpowder and see how it works." He waved his hand and accepted the dozens of jars of sulfur in the library with a smile. One jar weighs sixty kilograms, making a total of two to three thousand kilograms.
He asked the foreman: "How long did it take for this to be achieved?"
"We come to receive the goods on the 10th of every month. This is the result of more than 20 days." the foreman replied.
"How many people are there in total among you?" Zhao Hao asked again.
"There are two hundred people who can do the work."
"It is more efficient to purify with sulfur ore!" Mr. Zhao couldn't help but be speechless. In Jiangnan, there are two thousand workers producing sulfur for the group. In one month, they can only produce four thousand kilograms.
I heard that the speed of producing sulfur can be increased ten times in this way. Wang Rulong and others were also very excited, as if they had seen a beautiful tomorrow with unlimited gunpowder!
What, do you need more saltpeter? In this era where toilets are the basis of combat power, do you know how many people there are in Jiangnan and how many toilets there are? Let me tell you, there are six million toilets! Therefore, Daming¡¯s saltpeter itself has an unlimited supply!
"Poop is used as fertilizer, urine is used to make explosives, more people and more rows is the way to go!"
Don¡¯t underestimate this flavorful method of cooking saltpeter, it was the biggest military secret in the Middle Ages. Including Ming Dynasty, it has been strictly kept secret from the outside world, even to the loyal North Korea. On the one hand, the Ming Dynasty deceived the people of the Li Dynasty that "the saltpeter is extracted from sea water" to eliminate the possibility of the Li Dynasty making their own gunpowder. On the other hand, a very small amount of gunpowder trade was used to control North Korea's military strength.
&n??. "
The afterglow of the setting sun illuminated her face red.
"It's so comfortable" Mr. Zhao sat in the steamy hot spring and suddenly suggested: "In Japan, men and women bathe together. As the saying goes, we should go to the bar together."
"Really? Is there still such a rule?" Qiaoqiao was very moved when he heard the words, and immediately woke up, covering his face and said: "How shameless!"
"It seems that the young master should go to the bar by himself." Sister Ma covered her mouth with a smile, put a cotton towel on his shoulders and stood up.
"I'm scared alone." Zhao Hao took her hand, looked at Ma Xianglan with clear eyes and said, "And you haven't told me why you are sad."
After hearing the first half of his sentence, Ma Xianglan wanted to make fun of him and get away, but after hearing the second half of his sentence, Sister Ma's eyes turned red and her whole body softened.
It turns out that the young master not only cares about the world, but also cares about me
"Yeah." She nodded imperceptibly and responded as loudly as a gnat.
