    In the impression of Chen Laoshi and his wife, in addition to cooking, salt is also used to prepare tanning agents, which was also invented by Chen Wanrong.  They had never thought of using salt to make soap. However, a magical scene appeared in front of them, and they couldn't help but be dumbfounded.

    Strange to say, what was originally impossible to hit with eight poles actually came true: some ointment-like light yellow things appeared in the pot.  For Chen Laoshi and his wife, who had no knowledge of chemistry, it was a fairy-like ability that appeared out of thin air, which was too hard to imagine.

    Looking at the surprised expressions of the two elders, Chen Wanrong understood their mood very well and explained: "Father, mother, the alkali added just now is saponification. When the oil is boiled in the caustic soda solution for a long time, it reaches a closed state. I am now  Salt is added to separate the soap particles from the water, this step is called salting out.¡±

    "Salting out?" Chen Laoshi muttered: "Salting out is good, salting out is good!" He was so shocked that he still hasn't come back to his senses. His words were too mechanical.

    Mrs. Chen Wang swallowed, her throat made a gurgling sound, she wanted to speak but couldn't.

    Chen Wanrong then explained: "The more salt I add, the more it will precipitate." As he spoke, he kept sprinkling salt into the pot.  As Chen Wanrong said, there were more and more light yellow soap particles, and eventually a thick layer floated on top, like a golden pancake.

    "So many?" Chen Wang was the first to recover, looked at the soap particles, and finally spoke.

    "What are you talking about? More is better, more is better!" Chen Laoshi looked at the soap particles in the pot, his surprise still not gone.

    Chen Wanrong clapped his hands and put the basin of salt aside. Chen Wanrong breathed a sigh of relief: "The salting out has been completed. The next step is to separate the soap particles and glycerin."

    Chen Laoshi couldn't help rubbing his hands and volunteered: "Wanrong, what should I do? You tell me, I will do it!" A few very concise words expressed his excitement.

    "Wan Rong, you go ahead and mother will listen to you." Mrs. Chen Wang was not left behind either.

    After salting out, the soap particles are in the upper layer, and the lower layer is a mixture of glycerin and water. The stratification is very obvious.  This situation is similar to the difference between tofu and water. It is very simple to separate them.

    "Wanrong, can this bucket work?" Chen Laoshi didn't wait for Chen Wanrong to speak and put a clean bucket next to the stove.

    As long as there is a container to hold the soap granules, Chen Wanrong picked up the ladle and scooped the soap granules into the bucket.  After scooping out the soap particles, Chen Laoshi quickly carried the bucket and ran into the house. Chen Wanrong couldn't help but be curious and asked: "Dad, where are you taking it?"

    "Can this treasure be left outside? It would be very bad if others saw it." Chen Laoshi has seen a lot of Chen Wanrong's magic in chemical engineering these days. In the past few days, making caustic soda and tanning agents was more difficult than making soap.  It's just childish. How can making soap be so wonderful? You don't need to think about it to know that this soap must be a great treasure. Why not hide it well?

    He was only halfway done, and he was too impatient. Chen Wanrong couldn't help laughing: "Dad, don't take it away, it's not finished yet."

    "Old man, Wanrong said he hasn't finished it yet, so bring it back quickly." Chen Wanrong is now at the level of a god in the eyes of Chen Wang. What he said is dogma, and it should be followed strictly, so he hurriedly urged it.

    Chen Laoshi was a little embarrassed and kept saying "Oh" several times before jogging back with the bucket and placing it carefully on the ground.

    Glycerin is the main by-product of the soap industry. It has a wide range of uses. It can be used as medicine and health care products. Its effect is very good. Athletes need glycerin.

    Of course, if there is nitric acid, powerful zha drugs can be produced.  The power of ** is huge, much more powerful than fire. If it appeared in the Tang Dynasty, it would definitely trigger a revolution, and the pattern of war would change dramatically.  The army of the Tang Dynasty was already good at fighting and invincible. If it got the help of the emperor, it would be like adding wings to a tiger, and the Tang army would become even stronger.

    These can only be good prospects. Under the current conditions, it is impossible to refine glycerol. Even if it is refined, there is no industrial chain and its use is limited.  What's more important is that the gun is extremely unstable and will explode at the slightest vibration. It is very dangerous and an accident will occur if it fails.

    ????????????????????????????????????????????????????????????????OUT flummox  We can't blame Chen Wanrong for not having the ability to make decisions. Anyone who knows the uses of glycerin would be just as hard to choose as him.

    When Chen Laoshi and his wife saw that Chen Wanrong had not spoken for a long time, they did not disturb him and stood quietly.  After a while, there was still no movement from Chen Wanrong. Chen Laoshi touched Chen Wang and smacked Chen Wanrong, meaning that he wanted Chen Wang to ask.  Mrs. Chen Wang rolled her eyes at him, meaning to ask you to ask yourself, and carefully asked tentatively: "Wan Rong"??¡­¡±

    Chen Wanrong woke up from his deep thoughts and said, "Forget it, there's no need to keep it."

    Although glycerin has a wide range of uses, it is still unknown when it will be extracted.  Besides, this is just a few things. If you really need to refine glycerin, you can do it later. Chen Wanrong, who thought about this, decided not to keep it.

    As if they had received an imperial edict, the two elders sighed and hurriedly carried buckets to scoop boiling water.  Chen Wanrong hurriedly reminded: "Be careful, don't get burned." He snatched the bucket from Wang Chen's hand: "Mom, please rest, I'll do it."

    "Wanrong, aren't you the same as a mother?" Mrs. Chen Wang was very happy that Chen Wanrong didn't want her to be tired and smiled.

    Industrial wastewater is one of the "three wastes", but this wastewater is an exception because glycerin can protect plants.  If plants protected by glycerin can grow well on saline-alkali soil, Chen Wanrong is not worried about causing environmental pollution. He mentioned that the ditch in front of the house has collapsed.  The father and son ran several times before emptying the waste water.

    Put some water in, clean the pot a little, put the soap granules in the pot, add some water, and finally add two ladles of caustic soda solution.  Chen Wang raised the fire to the maximum level and started the alkali analysis process.

    The purpose of alkali analysis is twofold. One is to add a certain amount of alkali to further saponify the remaining fat and increase the saponification rate.  The second is to wash away the glycerin and pigments remaining inside.

    After the water boiled, Chen Wanrong allowed it to boil for almost half an hour before scooping the soap particles into a clean bucket, carrying the boiling water away and throwing it away.

    ?Clean the pot, add water, soap granules, and bring to a boil.  After boiling for a while, separate the soap particles and water, then add water to boil.

    This is done to remove residual glycerin, caustic soda, pigments and soap gum.  After boiling twice, the soap particles were already very uniform. Chen Wanrong knew that the heat was up, so he sprinkled the rosin into the pot and stirred it evenly with a stick.

    After cooking for a while, the aroma of pine came up, and the aroma spread everywhere. The smell made him energetic. Chen Laoshi took a few deep breaths and said, "It smells so good! This rosin smells better than before!"

    When you are in a good mood, the things are good!  He was in a very good mood today, so good that he could hardly imagine it. Not to mention the rosin, even the slightest fragrance was fragrant.

    "You know it, but I don't know it?" Chen Wang gave him a big roll of his eyes.

    Rosin is added to increase the aroma, otherwise how would it be called soap?  There were no perfumes in the Tang Dynasty, let alone the essences we use now. To increase the aroma, we could only use local materials and use easily available rosin.

    "It would be better if you have a flower garden and if the season is right, you can pick some petals, mash them, and add their juice to it.  There is no flower garden in this extremely poor family, so Chen Wanrong can only use rosin.

    Putting the mold in place and laying it flat, Chen Wanrong scooped up the soap and poured it into the mold.  Use a wooden board to level the soap in the mold, then put the lid on it and press it with your hands. It is estimated that the pressure is firm. Then put a few stones on it at several points.

    "Wanrong, is this good?" Chen Wang stared at the mold and commented: "It's just like making tofu!"

    "Tofu? Can tofu be so good?" Chen Laoshi snorted, quite disdainfully.

    This busy work was really tiring. Chen Wanrong straightened up, shook his head, feeling more comfortable, and said: "There is still something to do, it's not over yet."

    Chen Laoshi was impatient and asked hurriedly: "Wan Rong, what else do you have to do?"

    Mrs. Chen Wang looked at Chen Wanrong and waited for his instructions.  (Remember the website address: www.hlnovel.com
