"Hey, it's really sweet? The Marquis asked us to taste it too!"

A group of alchemists surrounded him in surprise instantly, and Chen Xu dripped a drop on each of them. After tasting it, all the alchemists nodded and admired.

"Mr. Marquis, I didn't expect that boiling oil with alkaline water can make such sweet sugar liquid. How could we open a sugar factory in the future?" A priest was very excited.

"Yes, making sugar is much better than making perfume. Everyone likes to eat sweet foods, and the yield seems to be pretty good. I only used half a pound of tallow, and there seemed to be several taels of sugar water in the beaker..." Another alchemist raised the beaker and said.

"This is not sugar water, it just has a sweet taste. This thing is called glycerin. It can be used to make skin care products and apply it to your hands and face, so that your skin will not dry up and crack in winter. Of course, the best way is to make a flake cream for easy use and preservation..."

Chen Xu remembered the only cosmetics he had applied when he was a child, the iron box Pechoin, which was snow-white and delicate and fragrant.

Although the formula of the sauce cream is completely unknown and the production method is not clear, the main useful ingredient is glycerin, and in the end, it is enough to make a non-toxic and non-irritating skin care product.

What's more, glycerin is not only used to make skin care products, it can also make explosives. The power of nitroglycerin is an explosive that even criminals used will tremble. I heard that shaking hard can make oneself fry to pieces...

"You have just seen the process of saponification. It's very simple, but you can test and find the best ratio in terms of the weight of the oil and the amount of alkali. I will send you a few buckets of oil and sesame oil for you to experiment... By the way, look at the soap in this beaker to see the specific process and time of solidification..." Chen Xu told him to arrange it and then prepare to leave and go home.

"Haven and wait!" A alchemist named Ge Qing chased to the door.

"What else is there? But it's okay to say it." Looking at Ge Qing's eagerness to speak, Chen Xu said with a gentle smile.

"Marty, our laboratory is haunted..." Ge Qing hesitated for a moment and said with a slightly nervous look on his face.

"Haunted?" Chen Xu was stunned for a moment and shook his head with a smile and cried, "How is it possible, where did the ghost come from Lang Lang Qiankun?"

Seeing that Chen Xu didn't believe it, Ge Qing was a little anxious and secretly pulled Chen Xu to a remote corner outside the door and whispered: "Marty, it's really haunted. At midnight last night, I got up to pee at night and saw a green light in the laboratory, which scared me so much that I almost pissed my pants!"

"Green light?" Chen Xu pinched his chin and thought for a while, "Is it some kind of glowing green ore? I have said before that ores such as fluorite will also shine!"

"No, it's definitely not an ore. I've been searching next to each other in the laboratory this morning. I've never seen green minerals, asked others, nor have I seen green objects..."

"Who else knows about this?" Chen Xu's face turned serious.

"Mr. Xue knows that I mentioned it to him once in the morning!"

"Well, go and call Director Xue to Benhou to ask."

"Yes, Marquis!"

The alchemist left and soon called the supervisor of Xianfeng Taoist. Chen Xu asked about the situation, but the supervisor shook his head repeatedly and didn't understand it, and even blamed Ge Qing for seeing it wrong.

"This matter cannot be left out. I have said that chemistry is a magical subject. Perhaps it was caused by some experiments yesterday. Go back and ask everyone to carefully review yesterday's experiment process and repeat it. Arrange people to see if there is still green light appearing today. Perhaps this is also an amazing invention!"

"Yes, my subordinates must make arrangements!" The supervisor nodded quickly.

It is impossible to be haunted. At least Chen Xu believes that there are no ghosts in the world, and Chen Xu cannot determine what it is, but the laboratory will definitely not emit green light for no reason. It must be something or chemical reactions. These messy phenomena are simply too normal for this chemistry laboratory with a messy and primitive state.

Because the current chemical experiments are not much different from those of medieval European alchemists, in addition to some normal chemical experiments that Chen Xu usually guides, such as making potassium hydroxide with lime water and wood ash water, reacting alkali ore with lime water to produce sodium hydroxide, and high-temperature distillation of copper sulfate ore to prepare sulfuric acid, there is also the method of pounding all kinds of ores that you don’t recognize into powder and mixing them with acid and alkali solutions to see if you can get any new things.

In short, without a systematic chemistry theory, all research is not of great purpose, and the research method is very simple, with only acid and alkali tests and combustion and cooking. Chen Xu didn't care much, so he always asked these alchemists to do it by themselves, because Chen Xu remembered very limited knowledge of chemistry in middle school, and even the periodic table of elements has not been fully recalled.

On the way home, Chen Xu went to the newspaper office and asked Chen Ping to help him make two advertisements in the newspaper, one was to look for caustic soda ore, and the other was to collect black seeds.

Judging from the current situation, the industry for making soaps and soaps is no longer a big problem, but the preparation of lye used in the laboratory is more troublesome.

Potassium hydroxide is obtained by filtration through mixed reactions of wood ash water and lime water. Lime water is easy to talk about, but it is too troublesome to make wood ash water. Although it is easy to collect wood ash, every household in Xianyang City alone burns firewood to keep warm, and it is fine to get more than ten tons of them a day, but it is not suitable for large-scale applications and is very troublesome.

Sodium hydroxide is different. There are a large number of alkali lakes and alkali ores in nature, and even some saline-alkali beaches can be found in the salt and alkali. The main ingredients are sodium carbonate or sodium bicarbonate. Both of these are the best raw materials for caustic soda. Moreover, alkali is not unfamiliar to the alchemist and civilians in Daqin. Medical alchemists usually use it. In the past, Zhao Qing was responsible for finding these minerals, but now with newspapers, many things only need to be published in the newspaper. After a short time, someone will come to the door to provide clues and even transport the things to the Academy of Sciences.

In short, everything you are looking for in the Daqin Metropolis Daily is definitely valuable, and it doesn’t matter whether it is worth it or not. If you have a date or not, you can not only establish a good relationship with the Academy of Sciences, but also get thanked by the Hou of Qinghe. This is also a great honor.

Chen Xu collected black tree seeds for soap.

The squid tree is an ancient tree species, called the Muzi tree in some places. It is a very valuable economic tree. Trees, heart-shaped leaves, roots, barks and leaves can be used as medicine. It has the effects of insecticide, detoxification, diuresis, laxatives, and can also treat diseases such as cirrhosis and eczema dermatitis. The leaves in autumn are red and bright like fire, and are also a very valuable garden ornamental tree.

The mature black squid seeds are wrapped with a layer of snow-white wax. It is actually a kind of stearic acid that can be used to make candles. At present, Daqin is already widely used. In addition to making candles, this thing can naturally be used to make soaps instead of beef, sheep lard and sesame oil.

Daqin is still in an era of extreme shortage of materials. While Chen Xu is working hard to implement the iron pot plan, he has also made the Ministry of Revenue and the Agricultural College vigorously promote the cultivation of sesame, because cooking oil is an indispensable seasoning.

Although sesame oil can be obtained through cultivation, the yield is very low. If it is not well managed, a mu of land can only get half a stone or even ten kilograms. Therefore, ordinary farmers cannot eat a little bit of it. As for animal fat, it is even less than enough to eat it. When raising pigs and sheep is still not popular, animal fat is a severe scarce resource. As for butter, it is even more scarce. Since the invention of the Quaru Plow, the role of cattle has become increasingly prominent. Although cattle killing is not prohibited at the official level, no one will be willing to kill their own cattle. However, the Qin Dynasty is currently small and the territory is wide. The Liang Dynasty and the Liao Dynasty all produced cattle and horses. Therefore, the Qin Dynasty is not short of large livestock at present, but beef butter is not a luxury item that ordinary people with small families can afford.

In order to have a braised beef noodles in Xiaohe Village, Chen Xu waited for a full year, and the cow fell to death by drinking water in the river in winter.

Therefore, the best way to replace cooking oil with economic trees such as black sausage seeds. Moreover, large-scale acquisition of black sausage seeds can also give the bottom-level civilians an additional way to make money, just like purchasing flowers, mountain grapes, wild fruits, and jelly seeds. These things are not consumed by the poor, but they all earn money from the rich. In the end, the money is circulated to the hands of poor farmers in this way.

Chen Xu believes that after these two advertisements are published, they should be able to receive a response soon.

After returning home from the newspaper office, Chen Xu asked the housekeeper to get several buckets of lard and sesame oil to send to the chemistry laboratory. Then he arranged for someone to go to the experimental factory and asked Gongshusheng to help build a double-layer steamer. The saponification reaction temperature was too high, causing the oil to be burnt at high temperature and burnt, so it could be heated with steam like steamed wine.

Time flies the next day. After the trip, Chen Xu slowly took a bus to the engineering school again. As soon as he arrived at the door of the chemistry laboratory, he found that there were a lot of people surrounded.

"Well, it's really sweet as honey, delicious!" Chen Xu walked into the laboratory and saw Hu Kuan smiling with his eyes holding a beaker.

"Hide it quickly, the marquis is here!" A priest quickly pulled Hu Kuan's sleeve to remind him.

Uh, Hu Kuan shook his hand and hid the beaker behind him, nodded and greeted with a flattering smile on his face: "The Marquis is here!"

"Is it delicious?" Chen Xu's dark-skinned eyes could hardly see clearly.

"Hehe..." Hu Kuan smiled and blushed, putting the beaker on the workbench.

"Staffed drinking the experimental preparations will be fined 100 yuan. Can't you see such a large laboratory system?" Chen Xu rolled his eyes in anger.

"No, no, yesterday I heard a few priests whispering that the laboratory was haunted, and Kuan didn't believe it, so he came here to inspect it today. When he came in, he found that several guys were drinking honey water. So Kuan couldn't help but taste it and found that the honey was indeed very sweet. Are you planning to open a sugar factory?" Hu Kuan said with a careful smile.

"I said yesterday that this is not sugar. Although it is sweet, it cannot be eaten as sugar... Forget it, I can't explain it clearly to you, where is Manager Xue?" Chen Xu turned around and glanced at the group of people.

"Mr. Marquis, the supervisor took people to the warehouse to look for ore, and will be back soon..."
