“This taste…”

The firewood burned vigorously under the clay pot, and the water in the jar boiled in a short while.

The astringent smell of willow leaves and willow bark emanates from it.

Hu Wei and his servants both covered their noses.

Liu Jun didn't care.

When he was in school, he had smelled all the bad smells in the laboratory, and this little thing was nothing.

"It's almost done, take the gauze, cover it on the jar, and pour the water inside into another jar." Seeing that the water turned brown, Liu Jun ordered.

The two servants took gauze and used a wet cloth to hold the bottom of the jar to pour out the water.

The willow leaves and willow bark were blocked by gauze, and pure brown water flowed into the prepared jar.

After doing this, Liu Jun picked up two jars of wine on the ground and poured them into a jar of water, and asked the stewards to continue boiling, boiling the water inside.

This is the most critical step in extracting salicylic acid, adding alcohol.

Because it was just an experiment, Liu Jun did not prepare a higher concentration of alcohol, but just replaced it with the strongest wine in the royal palace.

Although the effect will be worse, it will not affect too much.

After another half an hour, the water in the clay pot gradually dried up. At this time, a white powder gradually precipitated on the inner wall and bottom of the clay pot, which was salicylic acid.

"Scrape out all the white powder." Liu Jun looked excited.

The clay pot he used was about half a cubic meter in volume. The salicylic acid cooked from so many willow leaves and willow branches looked like it was about a bowl of it, and it was already quite a lot.

"Prince."

Soon, Hu Wei held a porcelain bowl in front of Liu Jun.

It is full of powder, and it is estimated that there is 50 grams.

After taking the porcelain bowl, Liu Jun nodded with satisfaction, and this was successful.

The following is the effect of adding salicylic acid into rouge.

He was thinking that Tangyuan brought Qing'er and Ping'er back. The three of them each carried a small bamboo basket with many beautiful rouge boxes.

"Prince, the servants of the rouge have bought it." Tangyuan lowered her head, looking shy.

Liu Jun saw it and chuckled.

Maybe because I have to try it when buying rouge, I have rouge applied to my face and mouth.

The already pretty dumplings make them look a little more beautiful when dressed up.

Qing'er and Ping'er are still young and can't dress up. At this time, their faces are fancy and become big-faced.

The two of them lowered their heads and glanced at each other, smiling unstoppably.

"How valuable are these rouges?" Liu Jun asked.

With salicylic acid available, Liu Jun is planning to directly use the existing rouge technology to incorporate salicylic acid.

This way, the finished product can be produced immediately.

"By the prince, the most expensive one in the rouge shop is called Guifei Hong, five taels per box, three taels per box of this drunken flower face, and this kind of hibiscus cream is the cheapest, you can buy it for ten cents." The dumplings were displayed to Liu Jun one by one, "and there are also one taels per five cents..."

Liu Jun nodded slightly, and took out thirteen kinds of rouge in the dumplings, with different prices.

If you convert the price, one tael of silver is equivalent to more than three thousand in the contemporary world, which belongs to the category of high-end cosmetics. The cheapest ten cents are only equivalent to five or six yuan, which is quite popular.

"Why is this imperial concubine red so expensive?" Liu Jun asked.

"The shop's friend said that the imperial concubine red was transported from Fuyu Kingdom, and used the finest silk flowers from Fuyu Kingdom. The morning dew collected in autumn was secretly made of 77, 49 days." Tangyuan said.

"Breaking the truth."

Liu Jun glanced at his mouth secretly, and the contemporary "Qimin Yaoshu" detailed the configuration methods of various rouge.

Because he was involved in the compilation of technical information, he also helped to check it out.

Basically all the rouge is mashed with red and blue flowers and rose petals to extract pigments, then add honey and osmanthus oil to make a paste.

Add some pearl powder or something high.

This imperial concubine is so expensive, probably because it is the gimmick of the Fuyu Kingdom.

"Well, I know, go and do it."

Liu Jun's mind became lively. From this perspective, this rouge was too profitable.

Although he does not have Qiluohua, salicylic acid is also a gimmick.

Ordinary rouge can only be applied with blush and lip red. It can be applied with both, whiten, anti-inflammatory and acne, and exfoliating. It is simply too strong.

"This rouge?" Tangyuan was carrying a basket, and it was not right to put it in, nor was it right to take it away.

Liu Jun came to his senses, "You choose a few, and give the rest to the girls in the mansion."

"Thank you, Prince." Tang Yuan was happy and took Qing'er and Ping'er to go there.

Hu Wei looked at Liu Jun and was full of energy, "The prince asked the dumplings to buy rouge but he didn't need it, and there was also this white flour..."

"What white face! We'll expect him to get rich." Before Hu Wei finished speaking, Liu Jun laughed.

After walking back and forth for a few steps, he asked, "Can there be people who make rouge in our Jingyang City?"

"I don't know this little slave, but it should be that the recipe for rouge is not a secret. Sometimes the lady from the wealthy family dislikes the rouge pickled from the outside, and will collect petals by herself for the subordinates in the mansion to make it. The concubine often makes the green beads around her." Hu Wei said.

"oh?"

Liu Jun was delighted. He wanted to drag the rouge outside to make it, but now it seems that it is enough to make it in the royal palace.

Anyway, there are so many new maids and servants, and it is better to convert them into productivity than to be idle.

Thinking of this, he raised his foot and headed towards Ruyi Palace.

Thinking that once the rouge is made, the amount of salicylic acid must be raised, he turned to Hu Wei and said, "Don't be idle these days. Go collect willow leaves every day, boil this powder on the willow bark, and don't cut it around when taking the willow bark, so as to save the willow tree from being killed."

Hu Wei nodded repeatedly.

After pausing, Liu Jun continued, "Also, holly is OK, don't just pick up willow trees. If others ask what they do, you will say it is used to fertilize."

"The prince is brilliant." Hu Wei gave a thumbs up.

The royal palace is so full of willow leaves, which will definitely arouse the curiosity of others.

It is common for every family to use leaves to fertilize, so it can be evaded.

After waved his hand, Liu Jun asked Hu Wei to go quickly. Whether he could make this fortune depends entirely on this willow tree.

Hu Wei went by himself, so he hurried to Ruyi Palace and told him about making rouge.

"Nonsense!" After hearing this, Zhao Yuyan slapped the girl in her hand on the table. "A few days ago, my mother thought you had really changed your life. I didn't expect you to be so ridiculous. You, a prince, aren't you diligent in government affairs, but you go to make rouge. Isn't it a joke?"

"Mother, this is also a government affairs. Now the treasury and the inner treasury are empty and there is no money. How can the child feed the mouths of the soldiers and officials? If they can't feed them, who will do it for me? The child has a secret recipe that can make a unique rouge, which will definitely sell well, and alleviate the current urgent need." Liu Jun expected that Zhao Yuyan would be angry and prepared a speech.
