The temperature is not enough, what to use to make glass, you must know that the glass also needs to be fired at high temperature. This technology does not need to be questioned, just shout 666.

The dry distillation of nitric acid waited until the next day, it was dark, it was time to get off work, and it was impossible to pull out a glass cover.

The next day's schedule was all about the preparation of nitric acid, and the glass cover pulled out in the morning worked very well.

Zheng Xiong is here to supervise, and everyone in the glass factory is very hard-working, very quickly. Nitric acid has been prepared successfully, sulfuric acid has also been prepared early, not to mention glycerin, which has been hoarded a bit much recently.

The chemical name of nitroglycerin is glyceryl trinitrate, also known as nitroglycerin. It is formed by esterification reaction of glycerol mixed with nitric acid and concentrated sulfuric acid under heating conditions. It is very easy to explode, and it was developed by Nobel in the laboratory to the application of explosives. Nitroglycerin can also be used in medicine to treat heart disease.

Invented in 1847 by Sobrello, a chemist at the University of Turin, nitroglycerin was not originally used in the military, but to treat heart disease. He found that this sticky substance can be dissolved in alcohol, and it is made into a medicine that has a special effect on heart disease and angina, because of an accident, the viscous nitroglycerin became angry, and Sobrelo's hands and face were blown up bloodied, and almost lost his life, so nitroglycerin appeared as an explosive.

We know the most famous honorary award – the Nobel Prize. This great god made his fortune with explosives and became famous through the ages.

In 1866, nitroglycerin was developed to develop Denamai (an explosive, the main ingredient is nitroglycerin mixed with wood flour, saltpeter and calcium carbonate).

[Dangerous, do not imitate. 】

This thing is very dangerous, Zheng Xiong will not joke with his own life, and of course he will not force others, there must be brave men under the heavy reward, and it is in line with the common sense of our traversers to smash it with money.

One arm of 100,000 will not be less in reality, or even 10,000.

Money can make ghosts grind in ancient times.

Zheng Xiong held a mobilization meeting with the employees of the glass factory.

"The next thing is very dangerous, and I won't embarrass you, it's all voluntary. The salary is three times, and if there is an accident, your children's glass factory will provide them with adulthood, including the problem of your parents' pension. If you want to, you will stand up, and the official promises that as long as I am alive, they will not be less than a mouthful of food. ”

A group of people whispered, and in the end, it was estimated that Zheng Xiong's assurance had an effect, and the government would not take the lives of their craftsmen seriously.

Zheng Xiong's rising popularity among ordinary people is still very useful.

"Adult, the small one is willing, if there is an accident, please take care of the small family."

"The little ones are willing, too."

One voice after another sounded, Zheng Xiong's face was slightly heavy, he was afraid of anything, even if Zheng Xiong knew the ratio, the accident would still come.

"You are all good, I am very optimistic about this thing, and I will let you leave your name after it is produced."

A few people were a little excited, Zheng Xiong's achievements are obvious to all, and the things he has made have benefited countless people, and there must be a strong stroke in the history books. Hearing Zheng Xiong's assurance, several people almost danced.

The crowd of onlookers regretted a little, how could the little people have the opportunity to leave a name in history, the stories of high-ranking officials and dignitaries circulated on the paper, and an alternative life is also what people are pursuing.

After the mobilization, Zheng Xiong told everyone to get ready, took a few iron sheets to give a few people some protection, and commanded them remotely, far away.

It is human nature to be afraid of death, no one is an exception, and those who are not afraid of death are people of faith. Zheng Xiong has no faith, and it is instinctive to be afraid of death.

A few people were careful, slowly adding firewood, and one person was adding materials, if they could live, who would want to die.

Seeing that several substances began to react, several people breathed a sigh of relief, nervous, and stimulated, Zheng Xiong still hoped that there would be no accidents.

Fortunately, everything went well, and when the reaction was completed, some sticky matter was left behind to extinguish the flames on the stove, and several people looked happy, jumping and jumping over there, celebrating that they had survived.

Zheng Xiong looked gloomy, the last step seemed to have been completed, but it also planted a lot of people, surprises and accidents, you never know which one will be the first.

"Come here, don't move the solution."

Zheng Xiong shouted loudly, and the power was still very strong.

Several people trembled.

"Adults, a few small people can't help but see that this has been made, and I hope that the adults will forgive."

"Is this a matter of forgiveness for you, you have seen this success, and I have seen it, but this thing is very dangerous, in case you encounter it, it is a matter of human life, and you hope that your daughter-in-law will not be widowed."

"Yes, adults, the little ones will pay attention next time."

Having said that, no one knows what is going on in his heart.

Zheng Xiong looked at the disdainful expressions of several people, but decided to teach them a lesson, in case it was gone, he would feel a little guilty.

"Dig a pit, pile charcoal in it, put that thing in it, be careful, and finally get some firewood for him to light it."

I don't know Zheng Xiong's intentions, and a few people are not entangled, and the triple salary is still fragrant. The efficiency is also very fast, and digging pits and burying charcoal is trivial.

With the departure of a few people, Zheng Xiong took a few people to wait in the distance, this thing is unstable, and the collision does not know if it has any effect, so it can only be burned in a stupid way.

Nobel detonated it with gunpowder, but fire was just as useful.

As the temperature in the pit rose, the freshly made nitroglycerin gradually became irritable, and with a loud bang, a large pit was blown out of the place where the nitroglycerin was placed in the distance, and the soil was splashed everywhere.

The crowd of onlookers in the glass factory were stunned, especially the few people who started it in person, their backs were cold, and they hurriedly saluted Zheng Xiong.

"It's the little ones who are wrong, and they will never do it again in the future."

"This time it's a lesson for you, and next time, if there's an accident, you'll be gone."

"What the adults teach is that the little ones must remember it."

Flicked his sleeves.

"Tomorrow continues, this thing is a lifesaver."
