Here, Qiao Mu was chatting with Wen Hu's family, and Wen Fu on the other side was still unwilling to cross over by himself and do nothing.

Secretly made handmade soap in the study.

Unfortunately, he is neither a chemical engineering major, nor does he have any system assistance, only knowing that soap production requires lye and edible oil for saponification reaction.

However, he felt that this thing should be quite simple to do, and he only needed to experiment a few more times, and he could do it anyway, otherwise he would be blind to his identity as a traverser and a college student.

He had only been through this matter for less than a week, and he began to plan after basically understanding the surrounding situation.

The reason why it has been delayed until now.

That's mainly because of his alkali aspect.

There was a bit of an accident.

At the beginning, he asked the little guy to help him buy soda ash, and he specially named that he must buy soda ash.

But at this time, there is no soda ash.

Even soil alkali caustic soda is not easy to buy.

A lot of the time it's self-made.

Therefore, the little guy tossed for a day, and asked all the pharmacies and groceries in the county, but he didn't find any soda ash, so he could only have a worried face, and went home a little worried and said no.

Wen Fu was stunned at the time, and began to wonder if the name of ancient soda ash was not the same as the name of modern soda ash, so he specially described what soda ash was and what it looked like in front of that little guy.

After listening to this, the little guy pondered for a while, and then asked him if it was caustic soda with a little hesitation.

Wenfu hesitated for a while before remembering that caustic soda is also alkali, but the purity is not as high as soda ash.

So in the end, I nodded.

He nodded his head here, and the little guy immediately kept shaking his head, saying that he couldn't do it, saying that caustic soda was too dangerous, and only some hunters who were in charge of nitrate leather would have it, and ordinary pharmacies didn't have to sell it, and if the young master had an accident with caustic soda, he couldn't afford it.

Anyway, in the end, he didn't make it.

Not only did they not get caustic soda.

was also reprimanded by his wife.

Wen Fu, who really had no choice, recalled it again for a while, and then he had no choice but to hit the idea on the plant ash, planning to use the plant ash to make the soap first, and then take the made soap to talk to his wife about the conditions or something.

Now he is in the study, using the plant ash water made from the plant ash he stole a few days ago, ready to start making handmade soap.

It's just that he doesn't know exactly whether it's useful or not, so he specially made several control groups, and is gradually experimenting with different proportions and different amounts, intending to select the optimal ratio.

When the time comes, take the best and negotiate the terms with his mother.

As the first part of the precipitated plant ash water was poured into the first part of the lard he stole from the kitchen, Wen Fu immediately began to stir vigorously, and then stirred for about ten minutes without any change, the lard was still lard, although it had been somewhat fused with the plant ash water, but there was no so-called saponification reaction at all.

"Hey, no, isn't soap made by mixing alkaline water and cooking oil?

Do you have to use vegetable oil?

But there's no reason.

Didn't you say that it was made like lard in ancient times? ”

Looking at the mixture in the small jar that was not very harmonious, and even the lard itself was slightly solidified, Wen Fu pondered carefully for a long time, and then he wondered if it was because he did not heat it and did not let the lard melt, so the lumped lard could not be saponified.

However, there is neither a gas stove nor an induction cooker in his study, so he can only put it on top of the carbon basin to heat it if he wants to heat it, but now it is almost summer, and the charcoal basin has long been removed.

In the end, Wen Fu could only gather a few candles from his study, then light all the candles, and make a small stand by hand, and put the small jar on top of the candle to burn, while stirring slowly.

With the heating of the flame, the lard finally began to melt slowly, and the gray water of the plants and trees that had already been poured into it was also rapidly fused with the lard, forming a saponification reaction, but his reaction speed was much slower than the normal reaction.

Because the alkali content in the ash water of plants and trees is not sufficient, it is good for him to make each other saponify each other, how can he pay attention to speed.

It took nearly half an hour to toss like this.

Wenfu was about to stir his hands and fold, so he barely finished the first one, and got a soap that was slightly darker than the malt color, and the next thing to do was very simple, if you want to make it smaller, then put it in the mold to cool, and if you don't want to put the mold, then put it directly in the jar to cool.

Wait for the soap to condense and let it sit for two days.

Of course, this is because he uses alkaline water used as plant ash, and the alkali content is very scarce.

"Oh, this thing is so tired.

Forget it, the remaining copies are still waiting for tomorrow to get it, and you will have to write big characters later, if you get two more copies, there is no way to write big characters. ”

Wenfu was not a hardworking person in the first place.

When he felt that his arms were tired to death, he immediately chose to give up.

There is nothing difficult in the world, as long as you are willing to give up!

That's his motto all along.

Besides, after two days to go to the clan class, Mr. estimated that he would have to check the homework, although he accepted some of the instincts of the original body, but in all aspects it was still a little worse than the original body, it was already a little worse, if the hand was no longer strong, then the words that were written, must not be scolded to death by Mr.

At this time, there was no juvenile protection law.

Nor is there any suggestion that corporal punishment is not allowed.

Mr. will let you see what is called butt flowering and what is called hand swollen into steamed buns in minutes.

Therefore, Wenfu will never dare to relax.

When the first soap, which he didn't know if it could be formed, was ready, he quickly hid the remaining ash water and lard again, arranged the study as it was, and then began to move his wrists, ready to complete today's big character task.

More than two hours later, after Wen Hu had dinner at Qiao Mu's side, he found an opportunity to say goodbye and leave, and came back with the three pots that Qiao Mu gave her, intending to surprise his son.

However, as soon as she stepped into the courtyard, she heard the angry scolding of her father-in-law, which was obviously angry at her son, so Wen Hu immediately sped up his walking speed, and walked to the main hall in less than two minutes, and hurriedly spoke out to save her son:

"What are you scolding Fu'er again?

Fu'er is recovering from a serious illness, isn't it normal to fall a little behind in his studies, anyway, he is still young, and he will catch up in two months, you are still holding a rattan, what are you trying to do? ”
