The last time Guan Shanyue did an experiment on saponification reaction was when he was in high school, he thought that he had made a mistake, and hurriedly said: "But it doesn't hurt to say it!" ”

Zhang Zechang is not a pedantic person, turned around and came to the iron bucket, pointed to the caustic soda inside, and said: "It is recorded in the fifth volume of "Elbow Reserve Emergency" "Meat Eating Fang" written by Ge Hong, an alchemist of the Jin Dynasty: "Take white charcoal ash and diash in equal parts, and fry them like paste." Pen, fun, and pavilion www.biquge.info times should not be pre-made, and they will rest in ten days. And you can go to sunspots, which is very poisonous. "The villain once went to the mole for the prefect of Laizhou Prefecture, and the villain was sure that what he did that day was what the adults called caustic soda."

Guan Shanyue was confused when she heard this, and asked with a puzzled expression: "Guan has something unclear, what are the charcoal ash and ash you are talking about?" ”

"If you go back to your lordship, these two things are lime and plant ash, and you can get this caustic soda by adding water to heat them."

Guan Shanyue suddenly realized that the plant ash contained sodium carbonate and potassium carbonate, and the lime reacted with it in water to produce sodium hydroxide.

"Lao Zhang, you can rest assured, as long as you take protective measures, the 'poisonous' caustic soda will not be able to help you. You're the only one here who has touched saltpeter, so please dry that pot of nitrate, and I'll keep it for a while. ”

The pot of nitrate in Guan Shanyue's mouth is as white as snow, which was purified by the Ordnance Factory with Sichuan nitrate to remove impurities, and was originally used to prepare black powder, but now with the technology of making high-explosive powder, these former darlings have also been discarded in the warehouse of the Ordnance Factory.

He also watched Song Yingxing's "Heavenly Creations" before he knew that there was a rare thing called saltpeter in Duoyan City. Without saltpeter, you can't make nitric acid, you can't make silver ammonia solution without nitric acid, you can't prepare silver ammonia solution, and he can't really make this mirror for a while.

Zhang Zechang didn't dare to slack off, and put on deerskin gloves and white silk masks again and got busy. He muttered in his heart.

If saltpeter is sold without official guidance, it will be imprisoned. Daning and Sichuan are thousands of miles apart, and they can take out dozens of catties in one breath, which is really wealthy. I don't know how Lord Guan used his divine power to transport him to Duoyan City, could it be that he really has three heads and six arms.

Although he muttered in his heart, Zhang Zechang's hands were not idle at all, he quickly put the cemented pot of nitrate into the stone mortar, and grinded it with a hammer-shaped wooden stick.

Chen Ergou lit four stoves with the charcoal fire in the stove in one breath, the briquettes in the stove were made of fine white coal, and the flames rushed out several inches high, and the temperature in the room was rising rapidly, and the temperature in the room stopped rising until the hot people were sweating.

Batur, who had nothing to do, came to Zhang Zechang's side, and saw that he was using a wooden rod instead of the iron rod next to him, and said with a mocking face: "You old way, you don't need a wooden rod with an iron rod, is there something wrong with your brain." ”

Chen Ergou pursed his lips, looking like an uncle, you are really a cow, if it weren't for the fact that he was Guan Shanyue's personal soldier and couldn't afford to offend, he really dared to let him try it with an iron rod, "One nitrate, two sulfur and three charcoal, have you heard of it?" In the fireworks workshop in our hometown, there was also a big man who used to do it with an iron rod, hey, I calculated, he has been dead for more than ten years! ”

Batur is just burly, but his brain is not stupid, on the contrary, he is very clever, or Guan Shanyue would not have chosen him as a personal soldier. He quickly heard the meaning of Zhang Zechang's words, glared at him fiercely and hid aside.

The surrounding soldiers let out a burst of laughter, among which Chen Ergou was the most debauched and unscrupulous.

There was only one stove in the living room, and the temperature was obviously not as high as in the kitchen, so Guan Shanyue first carefully put the pot nitrate in the casserole integrated with the pot and stove customized from the ceramic factory, and then connected the casserole with a large glass filled with eighty percent water with a glass conduit.

After confirming that it was sealed, he took a briquette from the coal stove where it was burning, put it in the stove under the casserole, and began to dry burn.

Everyone had never seen these strange devices, and they all held their breath and watched Guan Shanyue fiddling with the objects in front of them like reading a book from heaven.

Taking advantage of the reaction, Guan Shanyue asked the soldiers to go to the kitchen and clean the glass according to the steps of cleaning it with caustic soda water and then with distilled water.

Time flies, and nitric acid is ready in the blink of an eye. The main ingredient of saltpeter is potassium nitrate, which is calcined in a closed container to produce nitrogen dioxide, which is dissolved in water to form nitric acid.

After removing the casserole, Guan Shanyue lightly put the huge glass on the table in the middle of the living room, and slowly poured the crushed high-grade silver into the cup with an excited face, and stopped after estimating that the proportion was almost the same.

Preparing the silver ammonia solution was the most important step, and he poured most of the prepared silver nitrate solution into a brand new glass, slowly adding ammonia to it. The ammonia is purified by crude ammonia obtained from dry distillation of coal, and he scoops the ammonia into it with a porcelain spoon while observing the situation in the glass.

When the precipitate was completely gone, he immediately stopped adding ammonia and added silver nitrate to it instead, until the solution was slightly cloudy.

Pure glucose is not available in this era, Guan Shanyue's first thought is to use grape juice, but now this season is not the season for grapes to go on the market at all, and in the end he had to settle for the next best thing and choose the more common brown sugar.

He stood next to the glass, and seemed to have made a lot of determination to add the brown sugar to the silver ammonia solution, and then stirred it up without hesitation.

The glass in the kitchen had long been spotlessly cleaned by the soldiers, and he carefully poured the prepared solution onto the flat glass with the appearance of his memory, and so on several times, only until the mixture covered the surface of the glass and accumulated the thickness of the fingernail cover, he stopped dumping.

After doing all this, Guan Shanyue breathed a long sigh of relief, feeling that she had never been so tired, as if the bones in her whole body had fallen apart, "Huh...... Sigh...... Lao Zhang, come here, there is still a glass over there, you try to smear it, but you remember, this silver ammonia solution should be prepared and used immediately, if it is left, don't feel distressed, you must throw it all away, or just wait to be bombed! ”

Zhang Zechang's heart tightened when he heard this, he was more life-sparing than ordinary people, or he wouldn't have gone to the cultivation path to seek the art of immortality, "Well, my lord, don't worry, what you did today, the villain has all remembered it in his heart." ”

Guan Shanyue nodded, stood aside, and watched Zhang Zechang pour the mixed solution onto the glass.

As soon as the expert made a move, Zhang Zechang's hands-on ability was extremely strong, and he mastered this skill after a while, and he smeared all the glass mirrors with the solution several times according to Guan Shanyue's requirements before giving up.

The temperature in the room was extremely high, about thirty or forty degrees, although people were overheated inside, it was a suitable temperature for mirror-making, and the silver mirror reacted rapidly on the surface of the glass.

After less than half an hour, everyone did not care about lunch, and rushed from the living room into the kitchen, and gathered around the preliminarily made mirror, which they had never seen before, and could reflect people so clearly, as if there was another real world inside.

Including Zhang Zechang, all the people regarded Guan Shanyue as a living immortal, and they unabashedly cast a worshipful gaze at him.

Guan Shanyue enjoyed the feeling of being worshipped, coughed, and said with a smug face: "Now this mirror is not a finished product, only a layer of protective vermilion lacquer on the back is called a finished product, if you add a beautifully carved frame, it is called ingenious!" Look at this little thing that makes you so excited, we will make colored mirrors in the future! ”

"Wow!" There was a burst of exclamation.

Batur blushed and came to Guan Shanyue's side, carefully rubbed the silver mirror in front of him with his hand, and said with a twist: "Big ...... Big...... My lord, can you use a glass knife to cut a small piece of Batur? ”

Before Chen Ergou could answer, he said with a wicked smile: "My lord, Batur hooked up with a Han girl, it must have been given to her, haha!" ”

Guan Shanyue let out a hearty laugh, looked at the eager eyes around her, and said with a smile: "Don't worry, when did I Guan treat you badly, everyone present in this mirror has a share!" Zhang Zechang, come, come, count the number of people, use a glass knife to cut a piece for each of them, there is a ruler over there, you don't want to favor one over the other. ”

Just when everyone was laughing and dividing the mirror, a hundred-household dragon walked in, knelt on one knee outside the door, and shouted loudly: "Lord Qiqiguan, Mrs. sent someone to send a message and was stopped outside the mansion by the general, and someone said that the word came from the palace, saying that it would be an auspicious day in three days, please go back to the house quickly to discuss the wedding!"

Guan Shanyue was stunned for a moment, and immediately understood that this meant that she could finally have a round room with Shuji's little beautiful girl, and took a big step forward from her dream of sharing a bed with three daughters, and said ecstatically: "Zhang Zechang, I think the current one is still a little bad, you can adjust the specific gravity of the solution more and record the most suitable one." Zizhuyuan is temporarily yours to use, if you have any requirements, just mention it, and our fortune mirror will all be entrusted to you! It looks like Guan is going to change to a bigger bed, haha! After saying that, he smiled lewdly and went home, ready to get married.
