It starts with the production team driving the big truck

Chapter 370 is majestic and expressive!
That’s right, it’s the retort method!

Sun Jianping poured the red-hot charcoal into the repaired furnace through the small circular opening reserved at the top. Although the weather was cold, he was still sweating. Miss Qian didn't feel how cold it was anymore, so she took off her coat and gave it to him again. Drape it on your body.

"You watch here first, don't let the fire in the furnace go out, I'll get the tools!"

After Sun Jianping finished speaking, he ran away. Qian Huijun was stunned for a moment. What tools do you need?
After a while, I saw this guy bringing two iron stove tubes that are common in rural areas, and two crutches!
"Look, when you pour the pyrite into the retort later, the iron and sulfur will separate due to the high temperature, and the sulfur gas produced will be like this..."

He took out another glass can, wiped the inside dry, then put it on the neck of the stove, and stuffed the surrounding area tightly with a rag.

Qian Huijun looked at Inventor Sun doing these weird things with a curious look on his face, and couldn't help but laugh!
The big fool in my family doesn’t ask for anything!
He had to make things that he could buy for a few bucks himself!
"Look, I'm starting to light the fire!"

Seeing that the fire in the furnace was almost burning, Sun Jianping put coal and pyrite into the furnace layer by layer.

To be on the safe side, he first put half of the basket in, then fastened the furnace barrel to the small opening reserved for the furnace and sealed it with mud, leaving only a small hole underneath to transport oxygen.

Qian Huijun curiously approached the glass bottle. She saw with her own eyes that bursts of yellow smoke slowly emerged from the stove. When it encountered the glass bottle, it condensed into drops of viscous yellow liquid at a speed visible to the naked eye. , dripping down the bottle wall!

"Did you see it? These are the sulfur gases produced by dry distillation. As the temperature rises, it enters the neck of the furnace barrel and condenses into a solid after being cooled..."

"Yes, Not Bad!"

Looking at more and more sulfur in the bottle, Miss Qian raised her thumb and said, "It seems that your chemistry foundation is very solid!"

"It's okay, so-so, third in the world!"

"Go, go, brag again!"

Qian Huijun squeaked at him, and Sun Jianping laughed. "I'm asking a question. I just put in about twenty kilograms of pyrite. How much sulfur can be produced under ideal conditions regardless of loss?"

"Well..."

"Do the math!"

"It should be about ten pounds and seven taels!"

"It's awesome!"

"Of course, it's not like I haven't studied chemistry before!"

Qian Huijun raised his eyebrows proudly.

The pungent smell of sulfur soon filled the air, and the two had to withdraw from the brick kiln. They stood outside and watched the yellow smoke slowly rising from the brick kiln. After all, it was an indigenous method, and the tools were far more sophisticated. If it is not up to standard, the furnace tube will turn around and leak air.

There is no way, the conditions in rural areas are like this.

When the reaction in the stove was completely over, Sun Jianping rushed in, covering his mouth and nose. First, he took off the glass can. There was a circle of yellow smoke lingering in the can, which was like a fairyland.

He handed the cans to Qian Huijun, cleaned the furnace, and then added the remaining pyrite.

When the sun was about to set, the retorting work of pyrite was finally completed. Looking at the two cans of sulfur in front of him, Qian Huijun took one with interest and took a small piece of sulfur tablet to hold the solidified sulfur solid. Dig it out, put it to the tip of your nose and smell it...

Well……

It stinks!

"This fool!" Sun Jianping took off the crutch section by section and scraped out all the sulfur attached to the inner wall. Seeing her sniffing the sulfur with her little nose shut, he laughed!
Stupid young lady money!

So cute!
The key is that this girl doesn't have any ambitions, so being a wife is the best thing!

"Jianping, do these sulfurs also need to be ground into powder?"

"Yeah, it's not easy to make something!" Sun Jianping pulled together all the sulfur collected from the stove neck and poured it into cans. "These two bottles should weigh fourteen or five kilograms, although Not as much as expected, but almost enough.”

"What to do with the paper?"

Miss Qian counted on her fingers. There was sulfur, saltpeter, charcoal and yellow mud everywhere. Now we were missing two things! Medicine twisters and paper for rolling firecrackers!
"I talked to Director Yang, and he said he would help me give me all the newspapers accumulated by the commune over the years. The most difficult thing now is the medicine twister...it needs to be ground into soft and thin rice paper with medicine powder..."

"Should we go to Hecheng to buy rice paper?"

"Well, if it doesn't work, I'll have to make a trip."

"Then I'll go with you!" When she heard about going to Crane City, Miss Qian's eyes lit up!

"Okay, I'll call you then."

Sun Jianping squeezed her little hand with a doting look on his face, and Qian Huijun nervously grabbed his hand and put it under her nose.

"Smell something!"

"vomit!"

Sun Jianping retched for a while!
What a strong sulfur smell!

It doesn’t stink either!

Yao Nianzi was not in a hurry. After cleaning the furnace, he took some hard oak wood, lit it and stuffed it in. Then he sealed the mouth with mud and kept it stuffy for a day and a night. He opened it the next day and took out the It's black and brittle, and it has a metallic sound when struck!

Gather the ingredients!

Gunpowder goes!

The proportions of gunpowder are the same: sulfur, saltpeter, and charcoal. The proportions of each raw material are different, and the effects produced are also very different. When sulfur is increased, the power of the explosion can be increased. When charcoal is increased, the combustion process is relatively gentle. When saltpeter is increased, the combustion is rapid, producing a large amount of gas in an instant and pushing the object out. .

According to the ancient method, the ratio is "one nitrate, two sulfur and three charcoal", and according to modern Western research, the optimal ratio is 75% nitrate, 10% sulfur, and 15% charcoal.

For example, when making the most common two-kicker, the purpose of the lower charge is to push the cylinder into the air. Therefore, when mixing the lower charge, a large amount of charcoal must be added to slow down the burning speed and provide lift for the firecracker.

In the previous section, more sulfur should be added to the charge to increase the power of the explosion.

And the most important thing!
It’s not enough to just crush these ingredients and mix them together. You also have to add water and knead them into granules!

The "wheat gunpowder" made in this way has a burning efficiency more than twice that of powdered gunpowder!
A small firecracker has a lot of sayings in it!
Sun Jianping went to Hecheng again and bought back two large pieces of soft and thin rice paper. Qian Huijun also got on the carriage and followed him. His legs became thinner after shopping, but he still enjoyed it.

As soon as she got home, she snatched a stack of rice paper and said she wanted to use it for drawing!
"No one will stop you from painting, but it's best to paint in our house. If you are painting at Uncle Chen's house, if you are seen deliberately looking for trouble, you will have to suffer!"

The eldest lady is naive and careless, Sun Jianping has to remind her!
People's hearts are separated from each other, and they don't know what to do!
Is it uncommon for people to be reported to someone for painting?

"Yeah, yeah, yeah!" The eldest lady broke out in a cold sweat, nodded hurriedly, asked him for the key to the "new house", jumped over the wall between the two houses, and entered the yard of Han Laowu's house.

"Wang Wang Wang!"

Xiaodou Bao was so angry that he jumped up!
If you don't go through the door, you have to jump over the wall!

You are making it difficult for me as a "security guard"!
As expected of an excellent Chinese pastoral dog, he already knows how to look after homes and homes at a young age!
"A little bit!"

Across the adobe wall, Qian Huijun stuck out his tongue at Xiaodou Bao, turned around and opened the lock on the door.

There was a candlelight in the room. Under the lamp, the beauty was sitting cross-legged on the Kang table. She was slightly dipped in light ink and stroke by stroke, she sketched a landscape painting of the Greater Khingan Mountains.

I hope no one will make irresponsible remarks when I draw this!

Qian Huijun curled his lips, bit the penholder, and added another eagle to the woods.

Mighty and majestic, extremely expressive!
　It’s the end of the month, please vote for me, brothers!

　　The New Year is coming soon, another year, alas! Life!
