Chapter 176
As for how to convert and use it, this problem is not difficult for these craftsmen and he doesn't need to worry about it.
After solving the size problem, a carpenter stood up and asked about the structure of the steam engine.
Fortunately, the questions he asked were not very tricky, he just got stuck in his cognition and couldn't turn around.
After Wei Wu's explanation, the carpenter immediately understood.
After that, there were no more questions, and Wei Wu continued to explain the basic scientific issues to everyone.
Of course, it is not the periodic table of elements, but the changes that occur in nature and the reasons for their occurrence.
Although it was not particularly detailed, it broadened the horizons of these craftsmen and gradually began to change their understanding of nature.
Time passed slowly, and Wei Wujiang had forgotten how long it had been.
It was not until someone knocked on the door that Wei Wu, who was giving a lecture, and the craftsmen who were listening to the lecture came to their senses.
Then I saw a middle-aged man walking in from outside with two somewhat timid young people.
"Are you the firearms craftsmen sent by the Ministry of Industry?"
Hearing Wei Wu's question, the middle-aged man in the lead immediately bowed and said:
"We are here to pay our respects to Lord Changle. The superior of the Ministry of Works has asked the three of us to come here to obey Lord Changle's orders."
Upon hearing this, Wei Wu simply waved his hand.
"Okay, it's not called an errand here. You are just like them, we are all here to learn new things."
After saying that, Wei Wu became a little worried that the Ministry of Works might recruit some unqualified people, so he asked another question.
"Since you're here, let me ask you a question first. If the answer satisfies me, you can come in and sit down."
"Do you think the current gunpowder ratio is perfect? Is there room for improvement?"
The three craftsmen had not expected that they would be tested as soon as they arrived.
However, this question did not exceed their knowledge blind spots, and the three of them immediately began to think about how to answer it.
At this moment, Wei Wu suddenly added another sentence.
"By the way, don't try to guess what I want to hear. I want to hear your truest thoughts."
After Wei Wu finished speaking, the three of them immediately nodded to show that they understood.
The middle-aged man was still calmer, and he kept his head down, thinking about something.
On the contrary, one of the two young men immediately gave his answer:
"Lord Changle, I think the current gunpowder does not need to be upgraded."
Hearing this answer, Wei Wu showed no expression on his face and just replied simply.
"Oh? Go on, I want to know how you came up with that answer."
Hearing this, the young craftsman bowed to Wei Wu again, and then continued:
"Then I said, I think what gunpowder needs most today is improvement, not improvement, because it is not perfect."
"Only after perfecting gunpowder can we consider improving it, and this can be seen from the changes in gunpowder."
"Early gunpowder was a medicine. It was first recorded by the Tang Dynasty Medicine King Sun Simiao in the Dan Jing, which was called the Fuhuo Sulfur Method."
The young craftsman glanced at Wei Wu when he said this, and when he saw that Wei Wu's expression did not change, he continued:
"The gunpowder recorded at that time was made from a mixture of sulfur, realgar and saltpeter, which is similar to today's gunpowder but different."
"During the Northern Song Dynasty, the gunpowder formula changed again, with the addition of herbs like Aconitum kusnezoffii, Wolfsbane, and Gelsemium elegans."
"The final ingredients became more complex but the power was unsatisfactory. When ignited, it would even emit billowing smoke and was even poisonous."
Hearing this, Wei Wu did not react on the surface, but nodded secretly in his heart.
It can be confirmed that this person has really studied the issue of gunpowder, otherwise he would not be able to describe it in such detail.
Just as Wei Wu was expecting something, the young craftsman spoke again.
"Over the next hundred years, our predecessors continued to refine and refine the gunpowder, eventually removing the impurities and establishing the foundation for today's gunpowder."
