"Okay, Ming'er will start to let them enlighten and read.

Let Bai Peony teach, if they can't learn, just let Bai Peony teach them. When Xiao Qiuling heard this, she nodded in agreement.

These four little guys are really able to toss, either playing with the babies in the village, or scurrying around in the first four factories at home, and they can't be idle.

Sometimes she was afraid that they would go up to the mountains or play in the river, Xiao Qiuling had to keep an eye on them all the time, and she didn't let them go to these places, for fear that something would happen.

When the four little ones heard that they wanted her little aunt to teach them enlightenment and literacy, although they didn't know what it was, the four little ones were very afraid of their little aunt, and the little aunt was seriously angry, but she would really beat them.

Suddenly, the four little guys looked at Huang Shisu pitifully, and Huang Shisu saw this and said: "Don't sell miserable clothes with me, and follow your little aunt's enlightenment and literacy in the future."

If you don't study well, don't say that your little aunt beats you, I will have to prick you with a silver needle. ”

After the four little guys saw that it was useless to sell miserably, they all hung their heads and became depressed.

"Fourth brother, you can help me collect some river mussel shells later." After eating lunch, Huang Shisu instructed his fourth brother.

"Susu, what do you want a mussel shell for? What new products have you come up with? Thinking of this, Cangshu said with some excitement.

"Let's try it first." Huang Zisu smiled and nodded.

"Then what is the use of the new product you developed this time?" Atractylodes asked.

"It's for laundry." Yes, this time Huang Shiso wants to use the mussel shell to make soap.

This soap-making thing was reminded by her second sister-in-law before.

said that the four little ones were so dirty that their clothes couldn't be washed.

She thought that in ancient times, washing clothes was washed with plant ash, which contains potassium carbonate and can remove oil stains.

But this way of washing clothes is too laborious, and a lot of plant ash is burned before washing clothes, and the cleaning is not very clean.

It is also necessary to wash the ashes of the clothes with water many times.

As for the rich and noble, they are only cleaned with fragrant pancreas.

After taking out the pancreas of the pig, the fat attached to the pancreas is set out, the clean pancreas of the pig is washed and mashed, sugar, soda ash and a small amount of soybean powder are added, and then water is added to make a puree, kneaded into a pill, and dried in the sun, and the pancreatic soap is successfully made.

In ancient times, fragrant pancreas was something that could only be used by officials and nobles.

Therefore, she wanted to make a homemade soap so that ordinary people could use it.

"For laundry? Could it be that it is impossible to make fragrant pancreas? Cangshu asked.

"Almost! Fourth brother, hurry up and get the mussel shell, the more this thing, the better. ”

"Okay! I'm going. Cangshu nodded and walked out.

There is a big river at the head of Yunhe Village, every year in autumn and winter, every household in the village will go down to the river to touch the river mussels to stew rice beans to eat, which is also handed down from their village, saying that the river mussels stew rice beans to nourish the body.

The shell of the mussel can neither be used for decoration nor for feeding chickens, ducks, livestock or anything.

Every year, the villagers finish eating the river mussels, and throw them in their backyards and in front of their doors.

Atractylodes walked around the village and collected several mussel shells in baskets.

"Susu, I got this mussel shell back for you, how to get it next, I'll learn a little." It didn't take long for the Huang family to know that his family, Su Suyou, had developed a new product.

This new product is still used for laundry, no, the Huang family is curious, and they all came to the kitchen.

Huang Shisu didn't say much, and let them watch how they operated.

Just look at the process and they will know how to make the soap in the future.

Huang Shiso first cleaned the mussel shells, then put them in a charcoal furnace to fire, and pounded the burned mussel shells into powder.

The main ingredient after firing mussel shells is calcium oxide, which is commonly known as quicklime, and lime can be produced without natural rocks containing calcium carbonate such as mussel shells and limestone.

Of course, it would be better to have ready-made lime, so that there is no need to spend so much time and effort to fire the mussel shells, and also grind and sieve them.

After the mussel shells are burned crispy, the yellow perilla is taken out one by one, crushed, and ground into powder.

After grinding into powder, the yellow perilla is finely sieved again.

The purpose of this is to make soap that is more delicate to use without roughness.

After grinding the mussel shell powder, set it aside for later use.

Next, yellow perilla is burned to produce plant ash, which is used to produce an alkaline substance that provides an alkaline substance for soap making to promote the saponification reaction.

However, when Huang Shisu was boiling alkaline water, she also put some osmanthus flowers to boil together.

At that time, the boiled water will have a faint fragrance of osmanthus, and if you go to make soap, the washed clothes will have a faint fragrance of osmanthus.

The boiled lye is filtered out of the alkaline water with gauze, the pounded shell powder is added, stirred evenly, filtered again with gauze, and then left aside to precipitate overnight.

After the second day, yellow perilla, chop the prepared lard, put it in a large pot, slowly boil it over low heat, and then borrow a colander to put out the lard and let it cool for later use.

Pour the upper layer of lye stratified from the mixed lye that has been left overnight into the lard at room temperature, then mash the coarse salt and add it to the mixture of lard and alkaline water.

Fine salt can be sucked with salt to precipitate the soap, and then stirred continuously in one direction to fully mix the alkaline water and lard, resulting in a saponification reaction, which converts fatty acids into soap and glycerin, and when the oil gradually becomes a sticky paste, it can be loaded into a bamboo tube to set the shape.

Leave for three days, when the soap is well condensed. You can remove the mold from the bamboo tube, and then cut it into pieces of soap, let it slowly build, and the effect of washing dirty clothes will be better.

"Alright, that's it." After Huang Shiso gradually turned the grease into a sticky paste, it could be put into a bamboo tube and set, she clapped her hands.

"This fragrant pancreas is ready?" Huang Zhang's looked at it from beginning to end, and saw that it was not difficult to make fragrant pancreas, that is, it was made with mussel shells, grass and wood gray water and lard.

It seems too simple.

"You still need to wait for three days, and after three days, you can cut it into pieces and take it for laundry.

However, if you store it for a longer time, the better it will be to wash your dirty clothes.

After three days, let's take it out and wash the dirty laundry again and see how it goes.

If the effect is still good, we can mass-produce this soap.

In addition, the soap that is mass-produced is not expensive, it is cheaper, and it takes the route of ordinary people, with small profits but quick turnover. Huang Shisu told her grandma.
