Poor family mother and son

Chapter 542 Nitrogen
With the hot weather and the cooking, Chu Qing can be said to be careful in every step.

Due to lack of attention and lack of proficiency in making it for the first time, Chu Qing didn't dare to make too much, and only made less than ten catties.

Once the gunpowder has been blended, it has to be tested for success.

The method recorded in "Wu Bei Zhi" is: "...Pile a piece of paper on the paper, burn it with fire, and the medicine will go away without hurting the paper."

There is also a more frightening method of detection: "... take medicine in the palm of a person and burn it, but the palm is not hot...".

These are the standards for testing the gunpowder used in firecrackers in the Ming Dynasty, and check the burning speed of gunpowder.

Chu Qing had confidence in her gunpowder, but she didn't dare to test it on her palm, so she chose the first method.

Scooped out half a spoonful of gunpowder and wrapped it in paper, Chu Qing took a stick of incense to the toilet.

Summer toilets always smell very strong, and no one will be suspicious of the root incense.

On the contrary, Chu Qing didn't go to his special "Gong room", but went to the common hut in the northeast corner of the courtyard, which made people wonder.

"It's not close!" Chu Qing said something perfunctory to Mu Nianci and ran away.

"Near?" Mu Nianci looked towards the public latrine, and then looked at the direction of Chuqing's yard, it seems... the distance is not much different!
Lighting the incense, unfolding the paper bag on the ground, Chu Qing was lucky enough to let the two touch each other.

"Shua!" The light was blazing and disappeared in a flash.

Chu Qing shook the paper, turned it over and over to see, except for a piece of blackened paper, there was not even a burnt hole.

"Okay!" Chu Qing patted the ashes that didn't exist on her hands, very satisfied.

Now there is another key issue, the shell.

Chu Qing really wanted to make a grenade, but she didn't have time to think about how the firing pin and fuze worked, and she couldn't make a grenade shell in a short time.

She couldn't even figure out how the kind of smoke bomb mentioned in Xiaobao's letter could explode and smoke when it was dropped.

When Chu Qing was a child, he and his friends tried to smash firecrackers with a hammer, and they needed to hit the same point several times vigorously to explode.

This reason is easy to explain. If you hit it with a hammer, the internal energy will increase, and the temperature will rise. When it reaches the ignition point, the internal energy will increase rapidly. If it cannot be released in a short time, an explosion will occur.
But if it can explode with just a single fall, then the person who fired the smoke bomb at Xiaobao must have surprisingly strong hands, right?
In any case, first make twisters and light them with an open flame, and they will be regarded as powerful firecrackers.

In the end she chose to use a porcelain bottle as the casing.

She just found this.

The ladies in the family thought that the soldiers smelled of sweat, and it was too hot to use an incense burner, so they bought a bunch of cheap incense and sprinkled it all over the house, freeing up a lot of bottles.

These bottles are shaped like a one-handed hammer, with a palm-length neck and a tennis-ball-sized belly. They are easy to hold, like grenades.

Carefully fill ten vials of gunpowder, and begin carefully mixing potassium nitrate and sugar.

Three parts potassium nitrate and two parts brown sugar, no baking soda is ok, will ponder that later.

The temperature is still controlled and the fire is simmered slowly. In order to prevent sparks from jumping up, Chu Qing used the stove grate. This is the first time she misses the induction cooker so much.

Soon the powdered sugar softened and became viscous. Stir it carefully and watch the contents of the pot drooling.

When the paste turns dark brown, slowly pour it into a small porcelain bottle, before it hardens, insert the twister into it.

Ten vials were filled with the boiled nitrous sugar, which was a "smoke bomb".

All the twisted seeds that were exposed outside were wrapped in red paper, and they still looked like perfume bottles.

The rest of the materials were clearly classified into jars, sealed, and placed in a cool place inside.

Find a place to test the effect first.

An hour later, the nitrous sugar was completely cool.

"Ah yes!" Chu Qing walked out of the room, "How about taking a look at this?"

Chu Qing handed the small porcelain bottle to Zhuo Yao: "Light it up like a firecracker."

Zhuo Yao did as he said, lit the twister and ran away, then covered his ears.

I saw a lot of smoke coming out of the small porcelain bottle.

"Why didn't it ring?" Zhuo Yao was puzzled.

Chu Qing: "Tell me, is this the thing Xiaobao painted?"

Zhuo Yao pursed his lips: "It should be... right! Boss, did you really make it out?"

Chu Qing nodded: "Well, that's fine. However, Xiaobao's letter said that it would explode if it was dropped, and smoke would come out. I can't think of how to do it. I can only light an open flame."

Zhuo Yao was very excited: "That's not bad, boss! This thing... Make this thing bigger, put it in a bamboo tube, add some chili powder, lime powder or aconitum, arsenic... you can attack the city. !"

Chu Qing looked sideways.

sky!What kind of brains does this kid have? He didn't create "Wu Jing Zong Yao", did he?He thought of the poison smoke ball!

You can't tell the soldiers about these things, it's too scary, and you want to attack the city and loot the land!
Chu Qing decided not to take out the small explosive bottle, it was too dangerous for Zhuo Yao to see it.

She sent Zhuo Yao out to look for the fireworks workshop, to see if there were any firecrackers that would go off as soon as they fell.

At this time of year, there is really no place to sell firecrackers. Even if grocery stores can have them, there are probably not many varieties, so I can only go to the firecracker workshop outside the city to inquire.

Since he couldn't tell Zhuo Yao about this, he naturally didn't tell the kids at home, they were all dangerous people, so Chu Qing went to find Hou Ze.

Human thinking is so weird.

Because I know that these soldiers have actually been on the battlefield, I think that the dangerous factor in their bones is very active.

He didn't know that the boat gang also killed people and robbed goods (maybe it's because they follow Xiaobao now, so they subconsciously think they are all docile?), so they think Hou Ze is relatively kind.

After finding Hou Ze, he thought about it again. His brother had to help with the aftermath of this matter, so he shouldn't avoid him, so he asked him to call Wei Chengyi.

Then he also left the city with bottles of explosives and smoke bombs.

When Hou Ze went to look for Wei Chengyi, Wei Chengyi had just had a meal and heard his subordinates say that someone was looking for him, but when he saw that it was Hou Ze, he was dragged away without saying a word, leaving Monk Zhang Er confused.

There is a small basin on the east side of the Dou Iron Mine, and a small lake in the center, because no one comes here because of the mine.

The three of them rushed here all the way, Wei Chengyi still didn't know what Chu Qing wanted to do.

Wei Chengyi: "No one is allowed to eat at noon, what are you doing here?"

Chu Qing: "I made a gadget, I want to see if it works."

Hou Ze, however, saw Chu Qing stuffing a bunch of small bottles into the burden, so he couldn't help joking with Chu Qing: "I see you carried a big burden of fragrance dew, are you going to give it to my brother? You are too polite, that thing should Let my brother send you off!"

The sons and daughters of the rivers and lakes should not be too thin-skinned, Chu Qing said: "Wei Chengyi, tell your brother what is an 'imperial widow'."
