"Okay, stop making trouble, Runniang, please bring me some lard."
Jin Feng smiled and pulled Guan Xiaorou and told her why he was here.
"Brother Feng, what do you want lard for?"
Runniang asked curiously.
Jin Feng usually doesn't cook.
But he still ran to the oil can with a red face: "How much do you want?"
"Give it all to me."
Jin Feng did not explain, but said: "There is also rapeseed oil, get me a can too."
"Give."
Runniang obediently handed over the oil jar.
Jin Feng hugged the oil altar and left, and Guan Xiaorou followed.
Not only Runniang, Guan Xiaorou is also very curious about what Jin Feng wants to do?
When they arrived at a deserted place, Guan Xiaorou grabbed Jin Feng and asked, "Master, why do you need the oil can?"
"Make soap."
Jin Feng said with a smile.
Not long after traveling through time, Jin Feng discovered that people in Dakang all used saponins to wash their clothes and hair.
It's okay for washing clothes, and it can be cleaned by rubbing it vigorously, but it's not good for washing hair. The ability of saponin to remove oil is limited. After washing, it's still oily and smells bad.
Fortunately, rich people can use rice water to wash their hair, which can remove some odor.
But who can ordinary people afford rice?
So not long after they got married, Jin Feng took the time to make two bars of soap for Guan Xiaorou to use.
One is used for washing hair and bathing, and the other is used for washing clothes.
"Soap is made from lard?"
Guan Xiaorou couldn't help but widen her eyes.
She can be said to be the first person in Dakang to use soap besides Jin Feng, so she knows the function of soap very well.
Since getting the soap, she feels refreshed every day and no longer has to worry about the smell of her hair.
Now Jin Feng actually told her that soap with excellent oil removal ability is actually made of oil?
Guan Xiaorou felt incredible.
It was as if someone told him that the fire in the stove was made of water.
But Jin Feng smiled and nodded.
In fact, the making process of soap is very simple, and the emergence of soap in history is also a coincidence.
Legend has it that a blacksmith apprentice accidentally put grease into a fire that had just been extinguished while working. The grease was flammable. The apprentice was afraid of causing a fire, so he quickly took the grease out together with the plant ashes.
When grease gets on hands, it is difficult to clean it with clean water. As a result, when the apprentice washes his hands, he finds a lot of white foam on his hands, and all the grease is washed away.
Then I discovered that the hard lumps formed by the condensation of grease and plant ash have particularly strong decontamination capabilities.
Soap just appeared.
Although it sounds unbelievable, Guan Xiaorou completely believes in Jin Feng.
Jin Feng said lard can be used to make soap, so it must be possible.
"Master, you haven't used up the soap you made last time. You don't need to make it, right?"
Guan Xiaorou said.
"I did it in a hurry last time and it wasn't very good. I'm going to do it again this time and the two old ones can be thrown away."
"How can that be done? What a pity it would be to throw such a good thing away?"
Guan Xiaorou couldn't handle two bars of soap very well. Apart from her, only Tang Dongdong, Xiao'e and Runniang could use them.
The third aunt had been coveting it for who knows how long. She said she wanted to borrow it several times, but she was still reluctant.
"It's just a piece of soap. It's not a good thing."
Jin Feng smiled and said: "When I make it this time, you will throw it away yourself."
In fact, soap should be made with grease and caustic soda, but there was no caustic soda last time. Jin Feng could only use plant ash to make his own caustic soda, and the quality of the soap he made was very average.
Now that he has obtained caustic soda and prepared vegetable oil and spices, the soap he made can be called soap.
In all aspects, it is not comparable to the soap I made last time.
"I definitely won't throw it away. It's okay to give it to the third aunt and the others."
Guan Xiaorou said firmly.
"I will make more this time and give one piece to every household in the village so that everyone can use it."
Jin Feng said with a smile: "Third Aunt will not necessarily want you when the time comes."
Dakang people attach great importance to filial piety and believe that the body, hair and skin are all inherited from their parents and cannot be easily damaged, so most people have never cut their hair since they were born.
Every time Jin Feng went to the brick kiln, he wanted to cover his nose because the smell of those men was so strong.
You can imagine how much sweat these men sweated after working for a day.
But they don't like to wash their hair.
More than once, Jin Feng saw small bugs burrowing in the men's hair, which made Jin Feng's skin crawl.
This also leads him to try not to look at the other person's head when talking to him now.
Two jars of oil should be enough to make a lot of soap, and each household can have a piece.
In fact, soap and soap are too alkaline and will be astringent when used to wash hair, and are not good for the hair. Jin Feng once thought about making shampoo and asked Zhang Liang to buy a lot of soapberries and polygonum multiflorum from the county government.
Waiting for medicinal materials.
However, shampoo is not like soap, it is common sense, and the production process is relatively complicated. Jin Feng studied mechanics in his previous life, and his understanding of chemical engineering was limited, so he has never been successful in experiments.
Later, he followed Qinghuai to Weizhou, and the work of developing shampoo was put aside.
Now that I have some free time, I can try it.
"Every family will receive one piece?"
Guan Xiaorou asked with some distress: "How much lard will it take?"
"Don't worry, this oil is enough."
Jin Feng said: "I plan to sell the soap to outsiders in the future. After the folks use it, I can give them their opinions. It is considered a market survey."
Guan Xiaorou doesn't understand what market research is, but she thinks what Jin Feng said is right.
Jin Feng carried the oil jar into the blacksmith shop, where a warehouse full of small pots, stoves and other tools had been prepared.
Two hours later, Jin Feng poured the liquid soap into the mold prepared in advance. The preliminary work of making soap was over, and the next step was to wait.
When the saponification is complete and the liquid completely solidifies into a block, the soap is made.
Looking at the three large trays full of soap, Jin Feng's eyes were filled with anticipation.
Although the textile industry also makes money, the money comes in too slowly.
And eggs cannot be put in one basket.
The market space for daily necessities is absolutely huge, especially when there is no competition.
Greasy hair is a problem for almost all well-off people. If done properly, a small soap can definitely make money faster than the textile industry.
Of course, the textile industry cannot give up.
After all, food, clothing, housing and transportation come first.
Ordinary people can cook their own meals and live in their own houses, but very few can make their own clothes from kudzu.
You may not wash your hair, but you must not wear clothes.
Therefore, the prospects of the textile industry are also very bright, but there are more competitors.
Jin Feng and Mancang moved the soap to a ventilated place together, and Zhang Liang came back with his comrade Hei Da.
Following the two men were two thin men in ragged clothes.
"Xiao Feng, these two are brothers from the Tie Lin Army, Da Zhuang, and Tie Hammer."
The big black man introduced him, then pointed at Jin Feng and said, "This is Mr. Jin."
"Brother Tieniu, is this gentleman the one who led our Tielin Army brothers to defeat the party members in Qingshui Valley?"
The two men glanced at Jin Feng, then turned to look at the big black man.
