Chapter 967 Solidification forming is very useful (subscription required)

"It's enough for the oil to turn like this. Let's put it aside to cool down now, and by the way, simply heat the lime water that was mixed before."

"The saponification reaction, the temperature is actually a very critical thing. If the oil is too hot, it is easy to make the soap out of shape."

"But if it's too cold, the saponification reaction will be uneven, so you can't make soap."

At this time, Li Yuan had already put the clay pot on the fire for heating, and during the whole heating process, Li Yuan kept measuring the temperature with his hands on top of the pot.

After a little heat, the clay pot was taken down.

"The temperature of the lime water doesn't need to be too high, just warm. Let me see how the oil temperature is."

Li Yuan put his finger on the bottom of the clay pot. At this time, the temperature of the pottery was still relatively high, but it was much better than before.

After another two or three minutes of cooling, Li Yuan just started preparing for production.

What was placed on the ground was freshly cooled grease, and what Li Yuan held in his other hand was the prepared lime water.Li Yuan slowly poured lime water into it with one hand, and kept stirring the oil with a wooden stick with the other hand.

Because he was not familiar with it, Li Yuan slowed down the whole process as much as possible so that he could clearly see the state of the oil and lime water and make adjustments.

"In addition to the temperature and amount of saponification reaction, the most important thing is to keep stirring. It can be said that as long as the stirring is even, it is equal to half of the success of the saponification reaction."

Just as Li Yuan said, after the two liquids were mixed together, Li Yuan's right hand never stopped for a moment.

For more than ten minutes, although the speed has changed a bit, it has always maintained the same posture.

Because the two of them didn't stay in the forest for a long time, Li Yuan only planned to make two bars of soap temporarily.

Lime water was poured into the oil, and as Li Yuan stirred, the difference gradually appeared.

Under Li Yuan's stirring, the originally blackened oil gradually changed from the previous transparent color to yellowish, and then gradually turned milky white.

The original liquid font turned into a cream-like paste, fine and viscous.

Seeing such a reaction, Li Yuan, who had been watching from the sidelines, was gradually relieved of his worries. It seemed... his first experiment was a preliminary success.

Li Yuan: "It seems that the saponification reaction is not bad, and the color has begun to fade."

However, Li Yuan didn't dare to be careless, and continued with the work at hand, waiting for the two liquids to fully saponify.

Studio.

"It's amazing, it's changed!"

"Is this how to make soap? It's not difficult to look at..."

"The youngest of the Li family is too powerful, right?!"

"Don't mention it, it really smells like soap."

"This texture reminds me of a cream cake..."

"But why is this creamy? Isn't soap solid?"

Li Yuan: "Of course it doesn't work now. After a while, it will be fully saponified, and it will naturally turn into a paste after cooling."

Li Yuan didn't have accurate data in the whole process of making soap, but relied entirely on his own theory and feel.

Even Li Yuan was not very clear about the specific ratio of the two liquids and the cooling time.

Fortunately, Li Yuan is careful and knows a lot of things. He has been observing the state of the soap during the production process, and he has mastered the time pretty well.

After mixing, Li Yuan continued to stir for more than ten minutes, and at this time the soapy liquid showed signs of solidification.

The small wooden stick in Li Yuan's hand could already stand in the soapy liquid without falling over.

"At this level, it should be almost plastic. If it is completely cooled, it will not be easy to plastic."

"We sprinkle the mosquito repellent juice we prepared before into it, and after stirring evenly, pour the liquid into the mold we prepared earlier."

As he said that, Li Yuan took out the two square molds prepared earlier that were stitched with leaves and branches, and put them aside for later use.

And the washed mosquito repellent had already been put aside, Li Yuan held the mosquito repellent with both hands and rubbed it vigorously, the green juice of the mosquito repellent soon dripped into the soapy liquid.

Drops of turquoise juice fell into the soap liquid. Li Yuan kept stirring and mixing with a wooden stick, and soon those turquoise juices disappeared into the soap liquid.

Because he was afraid of affecting the solidification of the soap, Li Yuan didn't dare to add too much, and the mosquito repellent effect of the soap produced by this method would last longer than that of direct application, so it didn't need too much.

The soap liquid after mixing is beige in color, although there are still some small impurities in it, but if you don't look carefully, you can't really see it.

"Fill the soap liquid with mosquito repellent, wait for it to solidify and then wash your body, it will have the effect of repelling mosquitoes directly."

"Okay, now let's put this soap liquid directly into the mold."

The amount of soapy liquid is actually not much, it is only enough to make two pieces, and it is just right to pour all the soapy liquid inside into the mold.

After installing it, Li Yuan found two more leaves to cover it to prevent dust from getting on it during the solidification process, and then put it in the basket, ready to take it away.

Studio.

"The anchor's hands are too skillful."

"Is this done?"

"I don't know if this soap can be molded..."

"it should be no problem."

"Don't worry, Mr. Li's craftsmanship has always been very good, and he won't let us down."

"This thing... Do you think it's really the same as soap? Can it be rubbed into bubbles?"

Li Yuan smiled and said: "I want to know if I can rub out bubbles? It's simple. You can try it after the soap has solidified. It won't take too long. It's almost... tomorrow morning. If it goes well, you can use it tomorrow morning." gone."

Studio.

"It took that long?"

"That's too fast... more than ten hours."

"It made me so excited."

"It's not that bad. I thought it would take a long time to make soap, but I didn't expect to wait longer for it to solidify."

"Be content, you can still use things like soap in the wilderness, and the treatment is pretty good."

"Yeah, it's already pretty amazing that the anchor can produce so many things that improve living conditions in such a poor outdoor environment."

"If I could live in this deep mountain and old forest for two days and couldn't help but not run, I would be amazing!"

Li Yuan simply packed up, put out the fireworks, filled up the water, took his things, and returned to the base 10 minutes later.

It didn't take Li Yuan to make soap for a long time, and he came back in about two hours. However, Hu Kai was not idle during these two hours. At this time, a lot of wood had been stored in the base. Far ordered to prepare.
