The stone inkstones at home were saved, but the atmosphere between them was even colder, and Liu Yuanshan didn't care! The person in the Dong family, whether you endure or resist, is the same, she will not give anyone a good look. Pen & Fun & Pavilion www.biquge.info

Two days later, Ergua and Edamame prepared the things, Liu Yuanshan stole a small clay pot in Dong's kitchen, and the three of them walked breathlessly with the things for a long time before going up Bald Mountain, looking for a hidden and spacious place near the stream, and then started work.

"We're going to make laundry soap! It's the kind that specializes in washing clothes, you two listen to me, what is happening here is the top secret of our Dragon and Tiger List, and no one is allowed to say it outside, otherwise, hehe, it is a betrayal of the country! Liu Yuanshan threatened, and the two little friends really resigned.

Looking at the pile of things in front of him, Liu Yuancheng held it in his chest: "That, edamame, pretend to be ashes!" After speaking, he took his two friends and started making soap.

The first step is to lift the soda ash solution in the plant ash, which should be the most difficult part of the work for him.

Liu Yuanshan first took out a large clay pot, filled nearly a jar of plant ash, and then used a small jar to fill the water, and slowly poured it into the plant ash, of course, the pouring speed of the water was very slow, until the plant ash and water mixed into a viscous paste.

After soaking in water, only half of the jar of black paste was left, Liu Yuanshan dug a hole in the middle of the ash of plants and trees, and filled the excess ash paste on the wall of the jar, so that it would not take long for water to slowly seep out of the small hole in the middle.

To be exact, it is the soda ash solution extracted by the soil method, and it is difficult to say how high the concentration is.

"Bring another jar!" Liu Yuanshan scooped out the leaching liquid in the ash paste with a spoon and put it in another empty jar, and then added a little water, so that after a few times, the soda ash in the plant ash was extracted.

Then change to a jar of plant ash and extract it in the same way.

I made a jar of high-concentration soda ash solution, it took almost two hours, look at the sky, there was still a period of time before lunch, Liu Yuanshan took out the quicklime and soaked it in water, and made a jar of lime water.

Then, the solution of the two jars is mixed in the third jar and stirred thoroughly, and the clear water that originally looked transparent instantly becomes turbid, and many fine particles are precipitated.

Liu Yuanshan laughed, and said secretly.

The solid powder that precipitated was calcium carbonate, and the remaining solution was the caustic soda solution of his dreams, but because the caustic soda solution heated up when it was mixed, all the entire clay pots became unusually hot.

Edamame and Ergua watched dumbfounded.

"Big brother, why did this jar get hot?" Edamame asked.

Liu Yuanshan didn't bother to explain to him, and said vaguely: "I have the power of immortals in this thing, you don't understand!" ”

As soon as he said the immortals, the two friends immediately knelt on the ground, and looked at the jar "dong, dong, dong" is three rings, and Liu Yuanshan, who was knocking, was stunned, and secretly knew not to give them these, but it was okay, so that there would be a fairy deterrent so that they would not leak information.

"Okay, let's get this East XC up, go home for dinner, and come back as soon as we eat, and we will have more work in the afternoon!" Liu Yuanshan was not afraid of people stealing their things, because very few people came over in this mountain, and he was afraid that some small animal would accidentally overturn the solution they had worked so hard to make.

So, he led edamame and Ergua to move the bottles and cans to a dry and spacious cave nearby, and then went home and eat!

After eating, I rummaged through the room, hoping to find one or two more containers, and I happened to see the clay pot containing osmanthus flowers, and when I opened the lid, the aroma came to my nose.

After a period of air drying, the original fresh osmanthus has now turned into withered petals, but the strong fragrance has not been reduced by this, and it seems to have become more intense.

Liu Yuanshan's expression moved, and he said secretly: When I was in school, I used to like to put osmanthus in ink to increase the fragrance, but now I can also put osmanthus in soap.

Give it a try!

Secretly took away a bag of osmanthus flowers, and just after eating in the afternoon, the three of them came to the mountain again.

The rest of the matter is simple, Ergua and edamame are two people to light the fire, and the other is to collect firewood. Because the caustic soda solution was too dilute after all, it was impossible to use this large jar of water directly to make handmade laundry soap, and he had to increase the concentration by heating and evaporating.

As for Liu Yuanshan himself, he was assigned a highly technical job: grinding osmanthus flowers.

His task was to grind the dried osmanthus flowers he had collected from his home and from his two friends into a powder that could be added to the soap to add to the fragrance.

To make soap, they need a mold, but Liu Yuanshan and they can't have any favorite molds, so they can only cut some bamboo nearby and drag it back, use a machete to break it down into small sections of a few feet long, and use a section of the opening as a mold.

In fact, it turns out that the concentration of the solution extracted from the plant ash is still quite high, and after half of the water in the clay pot is evaporated, there are solid crystals precipitated, indicating that the caustic soda solution has reached a saturated state at this time.

"Alright, the main event begins!"

Liu Yuanshan's eyes were full of excitement, and according to the instructions given in the divine book, he measured a certain proportion of caustic soda solution and grease (the grease is a mixture of vegetable oil and animal oil) and put it for later use, and then also used fire to heat and melt the grease into a liquid state and put it into a large clay pot.

When both liquids have cooled to about 40 degrees (of course, there is no thermometer here, and the temperature can only be measured by feeling), Liu Yuanshan began to scoop out the caustic soda solution with a spoon and pour it into the grease little by little.

"Stir!"

At the sound of the order, Edamame took out a stick and began to stir, and as the stirring progressed, Liu Yuanshan added the proportional caustic soda solution to the grease one by one, almost making a full tank of mixed grease.

In the process of making handmade soap, the most critical technology is to extract caustic soda, and the most laborious part is undoubtedly stirring. Liu Yuanshan clearly remembers that in his previous life, it took more than ten minutes to use electric stirring, and now it is estimated that it will take an hour to stir the grease and caustic soda solution by hand.

The three people took turns stirring, and it took almost two hours to stir the mixture, during which it was heated twice, and finally the osmanthus powder crushed into powder was put in, hoping to increase the fragrance of the handmade soap.

"I'm tired!" Liu Yuanshan wiped the sweat drops from his forehead, "Quickly bring all the bamboo tubes, it's time to enter the mold!" ”

The two friends took the bamboo tube one by one, Liu Yuanshan carefully scooped out the mixture with a spoon, and poured it into the bamboo tube little by little, and the two melons and edamame were responsible for wrapping the bamboo tube with rags and then standing next to it.

After all the solution was filled, twenty-five bamboo tubes were filled.

"Hey, hey!" Liu Yuanshan looked at the full bamboo tubes and smiled, and muttered to himself: "This bamboo tube can be cut into two sections of soap, and if one piece can be sold for one tael of silver, it will be about fifty taels!" ”

"What, a tael of silver?" Edamame leaned over his sweaty face, and his expression looked incredible.

Ergua is obviously not convinced.

"Okay, but it can sell at least five hundred wen!" Liu Yuanshan saw the unconvinced eyes of the two little friends, and began to drum in his heart, he didn't know much about the consumption level of the Ming Dynasty, although the big families were rich, but if they only bought a soap for washing clothes, many people should be reluctant to buy it.

"Alright, alright!" The two friends were suspicious, and Liu Yuan urged them to clean up the scene, and then move the molded laundry soap to the corner of the cave.

Afraid that if someone found out, he brought a lot of broken stones from the outside and piled them together, buried the bamboo tube inside, and only called it a day before leaving to ensure that nothing went wrong.

Two days later, the three of them came with knives to carefully break the bamboo tube, at this time the soap has been formed, but the chemical reaction has not yet ended, according to the experience of the previous life, if you want to make a good warm soap, at least wait a month to a month and a half.

The three of them cut the soap strip in the middle, one in two, and turned it into a round cylinder, with a diameter of five centimeters and a length of about ten centimeters. Since the size of the bamboo tube was about the same when it was selected at that time, the size of the molded soap was not much different.

The rest of the matter is to put the soap in a cool, ventilated and dry place with peace of mind, and after a month to a month and a half, you can take it out and use it.
