Among these viscous liquids, there is Li Zhiyao's soap. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 However, at this time, the soap is still mixed with other things and dissolved in water, and they must be separated by salting-out. Li Zhi poured the soda ash powder into the viscous liquid little by little, salted out, heated and stirred, and the sodium ions in the soda ash forced the soap to separate from the water. After heating and stirring for half an hour, and after standing for a while, the soap that Li Zhi wanted gathered on top of the solution.

However, such a product is still not pure enough, and there are impurities in it. Li Zhi thought about it and carried out heating alkali precipitation treatment, which obtained a soap with relatively high purity.

After the alkali precipitation is completed, a thick layer of yellow translucent solid floats on the solution, which is the high-purity soap that Li Zhi wants.

successfully got the soap he wanted, and Li Zhi was in a good mood. At this time, the temperature of the soap is relatively high, and it is still in a semi-solidified state. Li Zhi scooped out this layer of soap with a spatula and put it in a wooden box and squeezed it into a square. Then pour it out and place it on the kitchen floor to dry.

After an hour, the soap was all dry and took on a dull yellow color. Li Zhi took a piece and rubbed it in the water, and sure enough, the soap was rubbed out of a large amount of foam by Li Zhi. Li Zhi dragged the sackcloth on the ground again and again to stain it, and then used the soap to scrub it off. Sure enough, the dirt on the linen cloth was washed clean.

Li Zhi's soap production was successful! Li Zhi brought soap, which had never appeared in the late Ming Dynasty, to this world.

These soaps are the basis for Li Zhi to change the fate of the Li family! Looking at his products, Li Zhi couldn't help but feel a little arrogant, and even had the ambition to change the world with technology.

With one blow, Li Zhi made persistent efforts and made a second pot of soap. He cut the pressed soap with a knife and cut it into small strips. When the sun was setting in the west and the smoke was curling from each house, Li Zhi got 500 small bars of soap.

After a busy afternoon, Li Zhi was a little tired and sat on the ground against the stove.

Li Zhi was resting when his younger brother Li Xing walked in.

It was getting late, and Li Xing estimated that there would be no more guests, so he closed the shop and walked to the kitchen to prepare to cook. As soon as he entered the kitchen, he saw pots and pans scattered all over the floor, and five hundred small bars of soap on the floor. Li Xing widened his glasses and asked Li Zhi, who was sitting on the edge of the stove, "What are you doing?" ”

Li Zhi looked at Li Xing and said slowly: "You know the soap horn!" ”

Li Xing nodded and said, "I know, the rich and noble people use it to wash their bodies." ”

Knowing what soaphorn is, it's easy to explain. Li Zhi smiled and pointed to the small soap on the ground and said, "This can also wash clothes and body, which is better than soap!" ”

Li Xing didn't believe Li Zhi's words. He didn't know what Li Zhi meant, so he stood at the door of the kitchen and looked at Li Zhi hesitantly.

Li Zhi sat up from the ground, dragged the sackcloth on the ground and soiled it, stepped on it a few times, and then scrubbed the burlap with soap and water in front of Li Xing. After a while, when Li Zhi washed and wrung out the linen, the stains on the linen had been completely washed off.

Li Xing looked at Li Zhi's performance with a surprised face. Li Xing didn't expect this soap to have such a strong decontamination ability, and looked at Li Zhi in disbelief. He took the sackcloth from his brother's hand, trampled it on the ground, and then put it in the water to scrub it. After scrubbing for a while, the stain was still black. Obviously, water alone will not wash off these stains.

Li Xing wiped the stains with soap again, and then scrubbed them, and sure enough, with soap, Li Xing easily washed off all those stains this time.

His mouth opened wide in surprise, Li Xing didn't expect that there was such a magical thing in this world, which could wash away the dirty things so easily.

You must know that in Daming, washing dirty clothes is the most laborious physical work. If they wanted to wash their clothes, they had to go to the river and beat them repeatedly with sticks to wash them off. This kind of beating is not only laborious, but in the process of beating, the new clothes are quickly damaged by the old ones.

But with these soaps, it's a big difference. Nowadays, all you need is a little soap to get rid of the stain easily. It is labor-saving and economical.

This is definitely a revolutionary invention.

Although the facts were in front of him, Li Xing still didn't believe it. looked at Li Zhi with some wistfulness.

"How did you do this?"

"An old Taoist priest taught me!"

"Then why did the old Taoist priest teach you?"

Li Zhi smiled and replied lightly, "That's the secret." ”

The Li family is in business, and Li Xing is also very business-minded. After trying it out, Li Xing immediately realized the huge business opportunity in this soap. He looked at the little strip of soap on the ground and asked, "Are you doing this for sale?" ”

Li Zhi said with a smile: "No, this is a giveaway!" ”

"Giveaway?"

"By the way, this is a gift for those housewives, and when they know that this soap is good, they will come to our store to buy more! We gave away giveaways, and business will boom in the future. ”

"That's why you're making such a small one?"

Li Zhi stood up and praised Li Xingdao: "My brother is so smart!" ”

Li Xing looked at Li Zhi with a smile, not understanding how his stupid brother became so shrewd.

Seeing that Li Zhi had made such a powerful thing, Li Xing's attitude towards Li Zhi changed greatly, and he began to listen to Li Zhi's command with half a doubt. At dawn the next day, Li Xing followed Li Zhi and gave a small piece of soap at the door of his shop.

Li Zhi targeted women who were dressed well. If you give these soaps to men, they may also feel that they are useless and may throw them away after a while. If it is given to a woman from a rich family, these rich women have servants at home, and they do not need to wash their own clothes, and they are likely to throw away the soap as well. In the case of women from destitute families, even if there is a need for soap, they cannot afford it.

Only women from well-dressed middle-class families who need to wash their own clothes and can afford soap can give full play to the value of Li Zhi's gift soap.

The courtyard of Li Zhi's house is next to Dongcheng Heng Street, and there is a large flow of people at the door of the store, so Li Zhi can carefully select customers.

As soon as he opened the store, Li Zhi saw two well-dressed women walking together, and Li Zhi greeted him and presented him with soap.

"Two sisters-in-law, stay here, your pleated skirt is so beautiful, but if it's dirty, it's not good! Listen to me: We have a new high-grade soap in our store, which is specially used to wash clothes and bodies, the price is very cheap, and the effect is much better than that of soap horns. Rub it with water and rub it a little, the dirt on the clothes will be gone, and the effect of bathing is much stronger than that of soap, do you want to take a look? ”

"And such a thing?"

"How come I've never heard of this thing called soap?"

"This is a new product that has just been bought by the small store, and it is the first time someone in the entire Tianjin Acropolis has sold this, of course you have never heard of it. It's okay, I don't want money to give you a sample, you can go back and try it out and feel the effect of this soap. ”

"Okay, you can give us a piece!"

Li Zhi handed the soap to the two women and said with a smile:

"The two sisters-in-law each took a piece and took it. Here's the giveaway. The official product is twenty-five times larger than this, and the price is only twenty wen, which is absolutely fair. If the two sisters-in-law feel good after trying it, they must come to the small store to buy official products. ”

In the Ming Dynasty, there were very few people who promoted their products in the form of gifts, and the two women also got free goods for the first time, and they were full of freshness, and said happily: "If it is easy to use, we will come to buy it." ”

Li Zhi said happily: "I'll wait for you to come!" ”
