Chapter 113 Soap Making
Li Meier and Jiang Shanqing were very efficient. Jiang Shanqing made a list directly, and Jiang asked Baozi to buy the materials according to the list.

The most different thing about Jiang Shanqing's soap making method is that the soap base he uses for making soap is homemade sodium hydroxide. In fact, it is not difficult to make homemade sodium hydroxide. Sodium hydroxide solution can be obtained by fully mixing water. This can be said to be the chemical knowledge of junior high school, but the ancients did not understand the principle.

With sodium hydroxide, the following steps are simple. Heat the sodium hydroxide, and when the temperature reaches [-] or [-] degrees, you can add hot oil and keep stirring until it becomes thick, and it becomes more and more difficult to stir. It will turn into a sticky soapy paste like maltose, and you can stop stirring at this time.

This process is physical work, and Li Meier and Jiang Shanqing, two little brats, couldn't do it, so they asked Mrs. Qiu from the kitchen to help. She has been working in the kitchen with great strength, and it took about a quarter of an hour to mix the soap paste. up.

Add the stirred soap paste to the goat milk and stir, and finally pour it into the prepared mold, and the basic soap paste is ready.

If you are making flower soap, you can add dried flowers.You can also add some floral water to increase the fragrance.

The next step is to keep warm. Jiang Shanqing asked Jiang to find a quilt that was not used at home, and wrapped it in soap paste to reduce the loss of temperature. This step took about a day and a night.

After a day and a night, Li Meier looked at the pile of things that already looked like saponins, and anxiously asked Jiang Shanqing next to her, "Is this still okay?"

Jiang Shanqing smiled and replied: "It will take about three or four days to ventilate and dry. When the soap paste is completely saponified, it will be almost done."

"It's going to take so long..." Li Meier felt that she couldn't wait any longer, why is it so troublesome to make handmade soap.

"Naturally, such a good thing needs careful workmanship, and it can't be done overnight." Jiang Shi also watched it with the two of them, laughing.

Now she has more confidence in this handmade soap. The steps of making soap are not something ordinary people can understand.

Li Meier waited until three days later, Jiang Yanzhi came again. He was very curious when he heard Jiang said that Jiang Shanqing and Li Meier had made some handmade soap, and went to see the soap paste that was being ventilated.

After Jiang Yanzhi saw it, he was also very surprised. He was much more knowledgeable than Mrs. Jiang, and he knew at a glance that this was already a well-formed incense stick, but it was different from the ones sold in the market.

"I think this is almost done, can I have a try?" Jiang Yanzhi's heart was itchy, and he wanted to try this handmade soap.

Jiang Shanqing also felt that the handmade soap was almost dry, so he nodded in agreement, "Father, give it a try and see how it works."

Jiang Shi immediately asked Baozi to fetch a pot of hot water and let Jiang Yanzhi try the soap.

Jiang Yanzhi took the handmade soap and washed his hands first. He purposely stained his hands with some ink, but it was quickly washed off. After washing, he didn't feel dry like he used to use saponins, but was very moist. , He changed the steamed stuffed bun into a basin to clean whoever he was, lowered his head and washed his face. After washing, his cheeks felt very refreshed and did not feel dry at all, so he didn't need to apply moisturizer.

"Uncle, how are you doing?" Li Meier asked anxiously as she stood by.

"Very good. If there is such a soap for sale outside, I will definitely buy one and use it." Jiang Yanzhi replied very pertinently.After hearing this, Li Meier immediately clapped her hands, and shouted excitedly: "Great, our shop can be opened now." Jiang's side was also very happy, thinking that she had the formula of this handmade soap Well, the business of her shop is definitely not bad.

Different from other people's excitement, Jiang Shanqing is still relatively calm, but he still has some complacency in his heart, thinking, isn't it just a handmade soap? All over the world are not afraid!
"By the way, what is the cost of making soap?" Jiang Yanzhi thought of another key question. If the cost of handmade soap is very high, there may not be too many people buying it.

"It's not high, it just uses lime, lard, plant ash and goat's milk. It costs a few tens of dollars to make a pot, and a pot can be made into handmade soap for about 20 yuan. Such a good soap can be sold for ten yuan a piece." Wen Ke is not expensive at all."

It’s really not expensive. The soaps sold in the market are made from crushed acacia locusts and added with different spices. Because the spices are expensive, the price is very high. A small piece costs one or two silver. Generally, only rich people Only when they are bought and used, ordinary people use ordinary saponins.

Jiang Yanzhi also used the expensive soap sold in the market. Except for some fragrance, it is actually similar to ordinary saponins, far less comfortable to use than this handmade soap.

"Actually, if you still want to reduce the cost, you can replace the lard with other cheaper vegetable oils, and it's the same if you don't add goat's milk. Adding goat's milk will make it more moist, and it can also whiten the skin after long-term use." Jiang Shanqing stood aside added.

When Jiang heard that this handmade soap could whiten skin, her eyes immediately lit up. She knew the allure of whitening to a woman. As long as she took this as a selling point, the supply of this handmade soap would definitely exceed the demand.

Jiang Yanzhi nodded after listening, but looked at Jiang Shanqing even more strangely, he couldn't help asking: "Shanqing, how do you know this?"

Jiang Shanqing knew that Jiang Yanzhi would be suspicious, so he had already thought up his words. He hesitated for a moment, and then said with a dark expression: "I saw my mother make this handmade soap before. It is said that it is a recipe left by the previous dynasty. My mother also came from... Know there."

When Jiang Yan heard it, he understood that Jiang Shanqing's mother had been a maid in the palace, so it was not unusual to know how to make soap. He felt that he had touched Jiang Shanqing's sadness, so he reached out and touched his head, warmly Comfortingly said: "Shan Qing, your mother left you a lot of things, and she also hoped that you will live well in the future, so don't be too sad."

Jiang Shanqing still pretended to be sad, and nodded heavily, but he was greatly relieved in his heart, and finally got over it.

On the other hand, Li Meier looked at Jiang Shanqing suspiciously. She stayed with Jiang Shanqing all day long, and never saw him miss his mother so much. Every time he talked about his mother, his expression was calm. Today is What's wrong, I'm still feeling sad.
