Before lunch, the students came back, Li Dan and Mu Sirong took the students back to the school, Chen Qiudie went home directly, and shouted outside the door: "Sister Jie'er, I brought so many flowers, come and see which one you like the most!" ”

Sun Mengjie opened the door slammed open and rushed out with a big belly, "Let me see what flowers Sister Die'er has picked!" She snatched a handful of flowers from Chen Qiudie's hand, "This is peony, I like it, and this camellia, spring juan, purple beads, and cloves...... I've got it all! ”

Li Zicheng hurriedly said: "Jie'er be careful, if you want flowers, it's not easy, it's early summer, and it's everywhere outside the city." ”

"Mr. doesn't know, they went to Nanshan today, these varieties can't be found on the wasteland outside the city," Sun Mengjie took a pink peony, sniffed it, squinted her eyes, and said: "It's so fragrant, hey, I haven't seen it for a long time!" ”

Chen Qiudie almost smiled and bent over, "Sister Jie'er, if you want to talk about the fragrance of flowers, how can peonies compare to roses?" She wiped a white rose petal against her face, "It'll be fragrant all afternoon at least, and I won't wash my face at noon!" ”

"No, my favorite is the peony, in the layers, it can also differentiate flower buds," Sun Mengjie sniffed again, "It's a pity that this one is water red, if it's white, it's even better, Sister Die'er, is there any white one?" ”

"No," Chen Qiudie shook her head, "People only care about picking flowers all morning, and they don't even look at the Phoenix Pavilion......"

Li Zicheng was moved in his heart, Chen Qiudie said "fragrant afternoon", he immediately thought of perfume, perfume lasts longer, which woman in the world doesn't like perfume?

If it is sold to the south of the Yangtze River, not only the wives and concubines of the official eunuchs are vying for it, but they are also rich businessmen, who is not a group of wives and concubines? If you want to attract your own men, perfume is the best extension of women's body fragrance, and even the painting boats on the Qinhuai River are probably flocking to the palace, if you can buy them in the palace......

Li Zicheng didn't care about eating, and immediately went to the study, he clearly remembered that there was a perfume formula and process on his body.

Entering the study, he closed the door, pulled out the treasures that had been re-transcribed, searched carefully, and sure enough, found perfume.

Li Zicheng was overjoyed in his heart, slowly opened it, and after a while, he already had a general plan in his heart, and then went home for dinner.

After lunch, he gave the students a half-day off, but he hid in the study and thought about it carefully.

To make perfumes, the raw materials are not complicated, and now is the season when the flowers and plants are fragrant, and there are them in the wild.

Perfume is a high-end luxury, expensive and profitable, that is, once he makes a perfume, he is a complete monopoly and holds the pricing power of the perfume.

In order not to attract the attention of the imperial court, the sales market of perfume is still similar to glass, but it is a rich land facing the south of the Yangtze River, and the size of perfume is small, which is easier to transport than glass.

However, the manufacturing process of perfume is very complicated, or in other words, the chemical raw materials required are difficult to obtain for a while.

If you knead the flower juice directly from the petals, like Chen Qiudie, not only will it not be stored on the skin for a long time, but the fragrance will not be able to be chosen, and it is not guaranteed to get the perfume in the flowerless season.

What's more, such a "perfume" cannot be called a perfume at all, because it has not been purified and purified.

There are three main raw materials for perfumes: distilled water, alcohol and flavors.

The easiest thing to get is pure water, but water quality is quite important, and it is necessary to remove excess calcium and magnesium ion impurities in the water, and then use distillation to obtain pure distilled water.

Alcohol dissolves the essence to retain the fragrance, and when used, because it is volatile, it can quickly emit the fragrance when the perfume is sprayed.

But the requirements for the alcohol itself are also very high, requiring alcohol with a purity of 70 to 75 percent, and esterification.

Li Zicheng repeatedly observed the black and white letters, and chose the most practical method: add caustic lye to the alcohol, boil it for several hours, fractionate it, and collect the purest part of its aroma to use it to mix perfumes.

This will be the first time that perfume has come out, and there is no competitor, it stands to reason that there is no need to strictly follow the process book to complete, but the value of perfume lies in the word "incense", if because of improper technology, or impure raw materials, the smell of perfume is discounted, and even stinks after a period of time, then it will smash their own "money" process.

The flavor itself needs to be aged for more than a month before it can be mixed with alcohol and distilled water, and after stirring and precipitation, it will be aged again for at least three months.

If there is turbidity or precipitation, it must be filtered before the finished product can be bottled.

The most difficult part of this is the extraction of flavors.

Li Zicheng repeatedly read, thought, speculated, and analyzed, and only then did he sort out the most concise and clear idea according to the process manual.

Even if the process is complete, it will take at least half a year from the beginning of the extraction of the flavor to the finished perfume.

Waiting can only be wasted in vain, Li Zicheng said just do it, first ordered the distillery to produce alcohol with a purity of up to 75 percent, and at the same time mobilized his own soldiers to go to the field to pick flowers and plants.

Theoretically, any flower or leaf can make perfume, but Li Zicheng is making it for the first time, with some experimental properties, so he chose lavender, which has a stronger fragrance.

Li Zicheng bought four copper kettles with his own soldiers, collected some thin pieces of glass from the glass factory, and tinkered with them in the small hall of the Central Government.

Two days later, a urn and retort device like the distilled liquor of that day were made, but this time it was not a copper kettle, but a glass sphere in the shape of a copper kettle, the upper end of which was a slender glass tube, and there was still a live valve in the middle and lower part of the sphere.

Li Zicheng grabbed two handfuls of lavender from the pile, stuffed them into the copper kettle and looked inside, felt that it was not enough, so he added another handful, and then filled the copper kettle with water, and burned it with black charcoal underneath.

After a while, the clear water in the copper kettle was boiled, and the steam entered the glass retort through the air duct, and quickly condensed into water, dripping and dripping.

"My lord, what is this for?" He Xiaomi watched it for a long time, but he didn't see any doorway.

"Well, it's still early!" Li Zicheng was guarded by three personal soldiers, and the charcoal fire continued day and night, and if the water surface in the retort body reached the bottleneck, he would open the live valve on the bottle body and release clean water.

He particularly stressed that the clean water must not be drained out, and the water surface must be shut down above the live valve, otherwise, military law will be involved.

The three pro-soldiers shrank their necks in fright, "My lord, my subordinates must be keeping an eye on the retort." ”

Li Zicheng took the other three copper kettles home, closed the glass, and made them behind closed doors.

Perhaps it was because of the skill, and in just one day, another distillation device was connected, put into the small hall of the central government, and began to distill lavender.

Sun Mengjie saw what Li Zicheng was working again, and during this day's time, he almost didn't even get out of the door, so he couldn't help asking: "Is Mr. doing any shocking production?" ”

"Shocking?" Li Zicheng thinks that these words are quite appropriate, once the perfume comes out, the lady will not rush to buy it?

He glanced at Sun Mengjie, who was rippling in the water, the glass in his hand continued to be grilled on the fire, and said, "Has Jie'er heard of Yang Guifei?" ”

"Yang Guifei? Is it the one who smeared nectar on his body all day long to seduce Tang Minghuang? Sun Mengjie rolled her eyes, and the original warmth disappeared in an instant, "I heard that she was originally a beauty, but thinking about seducing men all day long, there is something wrong with her behavior......"

Seducing a man? Li Zicheng laughed, "Jie'er, Yang Guifei is the concubine of Emperor Tang Ming, born in the palace, what else can she do besides seducing the emperor?" ”

"Then you can't just think about seducing men all day long!" Sun Mengjie pursed her lips with a look of disdain.

"She seduced the emperor, her man, and he is not a eunuch or a minister, what's wrong?" Li Zicheng suddenly found that teasing a little woman like Sun Mengjie is also a very happy thing, at least it is much more refreshing than playing with glass, no wonder people say, "Men and women match, work is not tired"!

"Sir is not a good man!" Sun Meng glanced at Li Zicheng, lowered his head and stopped talking, but his eyes fell on the glass in Li Zicheng's hand, and he couldn't help asking, "What is this doing, sir, the glass hasn't been lit for so long?" ”

"Clicking?" Li Zicheng tried it, the glass began to melt, and he quickly made the shape of the bottom of the bottle after a few strokes, and then put the upper part on the fire to grill.

"Huh? How can this glass be bent? Sun Mengjie's big eyes suddenly became rounded, and two pills of mercury turned left and right in the eye sockets, "The student has a piece of glass given by the gentleman, and the student also makes a vase and inserts a bouquet ......of flowers in the future."

"Don't!" Li Zicheng hurriedly stopped it, Lao Tzu knew how much of this thing, how much tuition and how much time it spent, how much toxic and harmful gases were inhaled in the laboratory, and now there is only such a thing left, how can it be at his fingertips? "It's dangerous, and your glass is too thick to bend by burning!"

"Ah......h

"Jie'er, don't worry about the vase, this utensil of Mr. is to make perfume, that is, Yang Guifei painted all over the body to attract Tang Minghuang, at most half a year, it can be produced, at that time Jie'er should have given birth to a child, if it is applied on the body and face, you can seduce Mr. ......"

Sun Mengjie was about to fight, but her little hand was already raised, but she was worried about affecting the fetus in her womb, so she suddenly softened, so she had to slash Li Zicheng with her eye sword.

At this moment, Chen Qiudie had already finished her homework and came out of the inner room, she habitually leaned her head over, "My lord, Sister Jie'er, what are you doing?" What seduces and doesn't seduce? ”

Sun Mengjie was speechless for a moment, and glanced at Li Zicheng hatefully before relieving his hatred.

Li Zicheng laughed and said, "Butterfly, girls have a strange fragrance on their bodies, and men often can't stop smelling it, but ...... Once a woman has more contact with a man, this body odor will gradually fade or even disappear, and what this Lord is doing now is to restore and continue this fragrance on the woman's body. ”
