Splendid peasant girl

Chapter 297 Thinking About Soap
"This soap doesn't seem easy to handle, so let's not do it, think about other things!"

"Actually, it doesn't cost a lot of money. Money is earned and used!"

However, Ye Han refused to wrong his little sweetheart, and asked to go to the county town to buy some soap.

"I have other ways!"

Shen Qiqiao showed a naughty smile, a little embarrassing.

Ye Han raised his pretty eyebrows lightly. Although he was puzzled, he still believed in his wife.

The night was very dark now, so Shen Qiqiao went back to her room to sleep, but before going to bed, she went to the space specially, and brought out some good-growing vegetables, preparing to cook and eat tomorrow morning.

The next morning, when the sky was slightly bright, Shen Qiqiao got up to feed his younger siblings and Ye Han, a pot of corn and red bean porridge, a plate of fried steamed buns, five lettuce pancakes, plus a can of homemade milk tea, which was very rich.

After Ye Han got up, he punched a set outside the house, and then came back to wash and eat. Since Shen Mu and Shen Xiaolan were freed, they woke up late in the morning, and when they woke up, it was just in time for dinner.

After breakfast, the two little guys ran to work in the small vegetable field in front of the house, because there was no need to fry tea for the time being, Ye Han took a knife and a bamboo basket and went hunting on the mountain.

Shen Qiqiao took the opportunity to think about soap.

Put the black tea aside, she thinks it is most important to solve the problem of self-cleaning first, otherwise when the weather is hot in the future, how uncomfortable it will be sticky all day long?

Now she came to the edge of the haystack, picked a lot of weeds, put them together in a ventilated open space without other igniters, and burned the weeds.

These incinerated ashes are the legendary plant ash, which was often mentioned in high school chemistry, and contains alkaline substances, that is, there are "OH" roots in it.

The making of soap is actually a kind of saponification reaction, which is to react alkali and ester to produce alcohol and salt.

The saponification reaction usually referred to is the reaction in which oil is mixed with sodium potassium hydroxide to obtain sodium potassium salts of higher fatty acids and glycerin.

There is rapeseed oil on the fat side, which is then mixed with plant ash, and then steamed at high temperature.

Shen Qiqiao has never done experiments in this area. When she was studying, the school's teaching facilities were poor, and she had few opportunities to do experiments. When she returned home, she had a lot of homework to do. How could she have time to toss about these things?
Now it is really difficult for her to apply what she has learned to practice.

But Shen Qiqiao is not an ordinary person, in her previous life she was a CEO of a company who likes to toss and ponder, this doesn't bother her.

She collected the burnt plant ash with a cotton cloth, and then went to the stove.

She put the plant ash into another ceramic jar, added water to dissolve it, and put it aside, waiting for it to become a clarified liquid of plant ash before using it.

Then light a fire, find a ceramic pot that can be used as a container, put it in a large pot, pour a pot of water on the side, and prepare to heat it over water for a while.

Everything was ready, Shen Qiqiao was worried that it would not be a one-time success, so she concocted several plant ash solutions, and at the same time took out a newly bought bottle of rapeseed oil.

She first poured the solution into a water-proof ceramic jar, and when the water outside gradually heated up, she added rapeseed oil, and then kept stirring with a chopstick.

It is said that the hemp point that needs to be stirred at the beginning can allow the saponification reaction to proceed more fully.

Not long after, a layer of white foam appeared on the jar. It is estimated that this is the true face of the saponification reaction. The legendary soap?

But it doesn't look very good-looking, and it's not as colorful as the ones I usually use at home, and there is an indescribable smell.
