The principle of soap is very simple, that is, the chemical reaction between lye and oil to form high-grade fatty acid sodium, and then processing into shape, which is the most primitive soap.

In the supply and marketing cooperative, a piece of soap costs three cents and six, the countryside is reluctant to buy it at all, usually wash clothes with soap horn water to soak, and then use a mallet to beat, if the clothes are not contaminated with soil, even soaphorn water is not used, just rub it directly by the river.

This is also no way, although beating with a mallet can make the clothes cleaner, but it will make the clothes break faster, where can I beat them often?

Thinking of the soap corners, Xu Shuxin asked the second sister to find out the dry soap horns at home.

I don't know how alkaline these plant ashes are, whether they can be done, Xu Shuxin thinks it's good to try it with soaphorn.

"Soap horn? It was used to wash clothes, and when it ran out, it was gone. Xu Shuyu said.

There are not many soaphorn trees in their brigade, only two in total.

If the people in the brigade want soaphorns, they have to use them, and if they don't keep an eye on them, they won't be able to grab them.

When the soaphorn was ripe this year, Xu Shuxin relied on her flexible skills to climb directly to the tree and grab a bunch of them back, and after drying them, they were all received in bags, and when they needed to be used, they took some out and mashed them to soak in water.

Although he said that, Xu Shuyu didn't stop walking back into the house, but just after taking two steps, Xu Shuyu suddenly stopped, looked back at Xu Shuxin who was stirring in the basin with her hands, and asked her, "Xinxin, what you are doing now should be for laundry, right?" Is it soap? ”

"Soap? Can you make soap out of these? Xu Shuyan asked, looking at the dusty liquid in the basin in disbelief.

Xu Shuting also stared at the liquid in the basin.

Xu Shuxin: "Second sister, why are you so smart, you can guess it!" ”

She also thought that her sisters would definitely know what it was when it was formed, but she didn't expect that this was just the beginning, and the second sister guessed it.

Xu Shuyan looked at Xu Shuyu, "Second sister, how did you guess that Xinxin was going to make soap?" ”

Xu Qingmu listened to the words of the sisters, and also walked over, looked at Xu Shuxin's movements, and asked him, "Xinxin, can these really make soap?" I don't think the soap of the supply and marketing cooperatives is this color? ”

"This is a simple handmade soap, the color is definitely different from the one sold by the supply and marketing cooperatives, but the principle is similar, now I also try it, if it really happens, let's improve it and make it a beautiful color."

Xu Shuyu also replied to Xu Shuyan and said her conjecture, "I didn't think that the grass ash can wash clothes, and the soaphorn can also wash clothes, since Xinxin uses these to make things, it must also be related to these, so make a bold guess, isn't it soap that can wash clothes?" ”

Xu Shuyan: "Second sister, you are so smart!" ”

"That's right, second sister, you're so smart!" Xu Shuting also praised Xu Shuyu.

Xu Shuyu waved her hand, "What kind of smart am I, Xinxin is smart, she can even make soap." ”

Xu Shuxin didn't raise her head, continued to stir in the basin, and said in her mouth: "It's written in the book, it's in the high school chemistry book, and I also heard what others said, and I don't remember who it is." ”

At this time, Xu Qingmu and Xu Shuyan had already started to help.

Xu Qingmu said: "Do you want to stir like this all the time?" Xinxin, go wash your hands, just come to this thing, and Yanyan too, don't do it. ”

Xu Shuxin pulled out of the basin, "Then it's hard work." ”

Xu Shuyan continued, "Dad, I'll help too." ”

"Second sister, go into the house and get soap." Xu Shuting urged Xu Shuyu, and then asked Xu Shuxin, "Xinxin, will that person also tell the branch secretary about this method?" ”

She looked worried.

If someone else does, won't they miss this opportunity?

Xu Shuxin wasn't worried at all, "It's okay, even if this is robbed, I have other ways, and we can also use it for ourselves, and we can save a lot of money." ”

Xu Qingmu is the same as Xu Shuxin, "Yes, don't worry too much if it doesn't happen, this method doesn't work, let's think of another way." ”

After a while, Xu Shuxin felt that the ashes of the plants and trees had been stirred sufficiently, so she asked Xu Qingmu to stop, "Dad, it's okay, just leave it like this overnight, and we can use it tomorrow, now let's make soaphorns." ”

Next, Xu Shuxin didn't need to do it, she dictated, Xu Qingmu followed the steps she said step by step, first mashed the soaphorn, pounded it into a fine powder, and then fried it in a pot, then put it in a clay pot, put vegetable oil, that is, peanut oil, and then it was temporarily over.

Looking at the peanut oil in the clay pot, Xu Qingmu smacked his tongue, no wonder the soap of the supply and marketing cooperatives is sold so expensive, it is actually made of oil.

The little girl also said that even those plants and trees should use oil.

If that doesn't work, the oil ......

Forget it, let the child play if she wants to, even if it doesn't work, it's nothing.

That night, Cui Lanhua also made a meat sauce, which was made with pork and mushrooms.

Because Ji Jingan can't eat spicy food, she didn't put chili peppers.

The next morning, Xu Shuxin didn't deal with the lye soaked in the ashes of the plants and trees after getting up, and set off for the city with her sisters after breakfast.

Xu Qingmu and the seven sisters walked together, and when the commune was separated, Xu Qingmu also asked them, "Don't you really need your father to go with you?" ”

Xu Shuyue, as the representative of the sisters, replied to Xu Qingmu, "No, Dad, there are so many of us, we can't lose it." ”

Xu Qingmu had no choice but to respond, "That's okay, then you pay attention to safety, and you don't know how to ride a bicycle, if you can't do it, don't buy it yet, and buy it when your father is resting." ”

It's so far away from the city, even if you can ride a bicycle, it will take a long time to come back, and you can't fit seven sisters on a single bicycle.

Xu Shuxin: "Dad, don't worry, we will come depending on the situation, maybe we are lucky, there are also sales in the county, we will buy it in the county when the time comes, and we can also put it in Uncle Tang's place, and bring it back when we come back from the city." ”

Anyway, I'm going to have to buy the bike back today, and if the county or city doesn't have it, then let's talk about it.

It's a long way to get back to the city, but there's always a way to ride it back.

Under Xu Qingmu's repeated advice, Sister Xu Shuxin got into the car to the county seat.

After a bumpy journey for half an hour, they arrived at the county seat.

After getting off the car, Xu Shuxin saw that it was still early, so she proposed to go to the county's supply and marketing cooperatives to see if there were any bicycles, and if so, buy them in the county.

Should I say it or not, Xu Shuxin's luck is really good, when their sisters went, the staff happened to put the bicycle out.

Not much, just two.
