"Master Hou just came, and his subordinates have found out about the green light in the laboratory yesterday!" The old alchemist put down the cloth bag in his hand and said.

Chen Xu is mainly here for this today, so he breathed a sigh of relief and asked, "What is it?" ”

"It's this ore!" The old alchemist opened the cloth bag, revealing some bits and pieces of ore, the color of which was blue and gray.

Chen Xu picked up a piece and looked at it, and felt that the section had a slight luster, and it was mixed with yellow-green fine impurities, like quartz stone, and there was no taste after smelling it, Chen Xu looked through it in his pocket, found out a small black stone and observed it and said, "This piece seems to be flint?" ”

The old Fang Shi also took it and looked at it a few times and nodded and said, "What Master Hou said is right, this is indeed a flint!" ”

Chen Xu turned over the cloth bag again and looked at it, it was written the words "Twenty miles west of Jingshan, Nanjun", literally, these ores should be produced in Jingzhou, Hubei Province in later generations, and the ore is mixed with flint, maybe the locals found it by looking for flint.

"You don't think this stone will glow, will you?" Chen Xu picked up a piece of blue-gray ore again and looked at it over and over.

"Master Hou, this ore does not shine, the reason for the glow is that after Yu Yuan distilled this ore yesterday, there was some white substance left in the distillation bottle, and it would emit green light by itself in the middle of the night, so it scared Ge Daoyou who got up at night!" The old alchemist hurriedly explained.

"The distillation flask is still there? Take a look at Benhou! ”

"I'm here, Master Hou wait!" The Fang Shi named Yu Yuan, who came in with the old Fangshi, hurriedly ran to another workbench, and quickly brought over a round glass bottle, Chen Xu took it and looked at it, there was indeed a layer of milky white waxy substance in it, very little, but you can still feel a slight lubrication when you touch it with your hands.

"Master Hou, several of us saw it last night, and when it is very dim, there will be a green light in this distillation bottle, like a ghost fire in the wilderness......" Yu Yuan said with a pale face.

"The ghost fire of the fart, Ben Hou almost knows what this thing is......" Chen Xu sniffed his fingers slightly, feeling a garlic smell, so he quickly ordered the basin to be brought to wash his fingers before saying, "This thing is called white phosphorus, when exposed to the air, it will emit green phosphorescence in the dark, fortunately it is winter now, if it is summer, it will definitely burn, and also, this thing is highly poisonous, don't get it in your mouth!" ”

"Master Hou is saying that Yu Yuan got a poison out of this ore?" A group of Fang Shi all gathered around to watch the flask with strange faces, and many of them shivered slightly, obviously if it wasn't for Chen Xu's reminder, maybe some people really had the intention of licking it.

"Don't be afraid, the avenue is divided into yin and yang, yin is the beginning of yang, yang is the end of yin, yin and yang are mutual, and the so-called poison does not need to talk about discoloration, although this white phosphorus is unintentionally obtained and highly toxic, but if it is used well, it is also beneficial to the country and the people, but it also needs to be careful and continue to experiment!" Chen Xu waved his hand to comfort a few words, then ordered to find a wooden barrel, put the flask in it, and then covered the wooden barrel with a large black cloth and said with a smile, "You poke your head in and take a look, you will know that Ben Hou is not wrong, white phosphorus will emit green phosphorescence in a dark environment......"

"Master Hou, I'll take a look first!" Hu Kuan couldn't wait to put his head into the barrel, and after a while, he shouted in surprise: "Master Hou, I really saw the green light!" ”

"Dean Hu come out quickly, let me wait and take a look!" A group of alchemists couldn't help but stir, and when Hu Kuan came out, they pouted their butts one by one and arched their heads into the barrel to watch, shouting in surprise and excitement.

After a group of people watched it next to each other, Chen Xu asked people to take out the flask, and asked a monk to carefully scrape out the white phosphorus inside with a piece of bamboo, and finally put almost a tablespoon in a beaker.

"Ladies and gentlemen, this white phosphorus is highly poisonous and particularly unstable, it will slowly volatilize when exposed to the air, if the temperature is a little higher, it will burn, the flame is green, just like the ghost fire in the summer of the grave wilderness scattered with corpses, so Fang Ben Hou said that there is no ghost fire in the world, in fact, the ghost fire in folklore is also called phosphorus fire, not a ghost ......"

"Everyone disperse, Ben Hou lit it for everyone to see the essence of the ghost fire, and bring the match to me......" Chen Xu instructed a priest to find a match, and after drawing several matches, he finally lit them, and then threw the match directly into the beaker.

"Boom~~"

The moment the burning match fell into the beaker, a blue-green flame rose from the beaker.

"Wow~~" A group of Fang Shi retreated in fright, and a large area was vacated, under the reflection of the green phosphorus fire, not only everyone's faces were reflected green, but the entire laboratory was extremely green.

"It's cold!" A timid alchemist swayed slightly.

"Hey, cold fart, Master Hou said it, this is phosphorus fire ......"

"What about you...... Why are you shaking......"

"Giggle...... Didn't ...... Didn't shake ...... Damn, why is your face green......"

"Yours is not green yet...... It's green, even the hat is green......"

Although Chen Xu explained that this is the characteristic of white phosphorus and is not a ghost fire, the explanation is useless, because no one has ever touched this kind of chilling green flame, and it is burning in front of everyone at such a close distance.

A spoonful of white phosphorus was quickly burned out, looking at a group of monks who were usually grinning but were now frightened and pale like quails, Chen Xu cried and laughed and said: "Okay, okay, don't be afraid, this phosphorus is not only in the ore, but also in animals and human bodies, especially in the bones, after the death of people and animals, the bones of the corpses will rot, these phosphorus will be slowly released, and the temperature will be higher in summer, it will burn by itself, so some people see ghost fire in the wilderness, if you don't believe it, Wait until summer to go to the barren mound with a lot of dead people......"

"This white phosphorus was discovered by Yu Yuan and Ge Qing, Ben Hou decided to reward each of them with two thousand yuan, and also, the refining test of this white phosphorus cannot be carried out in the chemical laboratory in the future, it is easy to burn or even explode, it is too dangerous!"

Yu Yuan and Ge Qing's faces suddenly turned red with excitement, and the rest of the laboratory also showed envious expressions and congratulated the two winning guys.

"Master Hou, you just said that phosphorus is highly toxic, but you don't know how to use it, or what it can be used for?" After a burst of excitement, Yu Yuan couldn't help but ask.

"Phosphorus is a very strange element, it can exist in many different states in nature, white phosphorus is toxic and easy to burn and explode, but after treatment, it will turn into red phosphorus, which is not only stable but also has no toxicity at all......"

When Chen Xu spoke, he picked up a box of matches and said, "You all know that matches are better than flint, but in fact it is not very convenient to use, sometimes you have to draw many roots to ignite, mainly because the accelerant in it is unstable and not easy to burn, if you use white phosphorus, it is very easy, but the nature of white phosphorus is unstable and highly toxic, it is easy to cause spontaneous combustion of matches and cause accidents, so if we convert white phosphorus into red phosphorus, and then use red phosphorus to make gunpowder, Then the match will be very useful and safe! ”

"Ben Hou originally let the Academy of Sciences develop matches, but it has not been successful, so there is no large-scale promotion of use, and now white phosphorus has been discovered, if white phosphorus can be converted into red phosphorus, then Ben Hou can prepare a match factory to promote matches on a large scale, and flint can be completely abandoned in the future...... Yu Yuan, Ben Hou handed over this task to you, if you can find a way to convert white phosphorus into red phosphorus, Ben Hou will apply for an invention patent for you, and give you the shares of the match factory, to ensure that the money you earn in the future will not be spent in several lifetimes! Chen Xu looked at this young Taoist priest who was about thirty years old and said.

"Hou Ye, rest assured, his subordinates will definitely complete the task!" Yu Yuan swayed slightly excitedly.

"Today this is an unexpected gain, and at the same time, this incident also tells you, chemical experiments do not ignore any details, maybe a small anomaly is an extremely significant discovery and innovation, in the future, we must not let go of any doubts, okay, today Ben Hou is to see the soap, you are all scattered, what to do!" After Chen Xu waved his hand and blew away Hu Kuan and a group of other irrelevant people, there were only more than a dozen monks left in the laboratory.

"Master Hou, this is the soap you made yesterday!" A Fang Shi took yesterday's beaker and put it in front of Chen Xu.

The color was slightly pale yellow, and Chen Xu gently pressed it with his hand and found that it was very soft, basically unlike soap and soap, it belonged to a kind of paste.

Is it because it hasn't been there long enough?

Chen Xu dug some out with his hands and tried it on his hands, and found that there was no difference from soap, it was indeed very clean, and the taste was no different from the soap of later generations, and there seemed to be a faint alkaline smell.

The alkaline smell is estimated to be the residue of alkaline water left over from the saponification reaction, as long as you test a few more times to adjust the reaction ratio of alkaline water and oil, but to make soap, you also need to add some floral essential oils.

In the following time, a group of alchemists were divided into groups to carry out different ratios of alkaline water and oil for saponification reaction, while Chen Xu asked the School of Engineering to clean up a remote and ventilated room, which was specially handed over to Yu Yuan to refine white phosphorus and experiment with making red phosphorus.
