In addition, the reason why this soap can remove stains is because it has a special molecular structure after fusion, one end of the molecule is hydrophilic, and the other end is lipophilic.

At the interface between water and oil, soap emulsifies the oil and dissolves the oil in the soapy water; At the interface between water and air, soap encloses the molecules of the air to form soap foam. The dirt, which was originally insoluble in water, could no longer adhere to the surface of the clothes due to the action of the soap, and the Gangping soap foam was finally washed off completely.

This is actually a very simple chemical equation, and people who have good chemistry scores know the truth.

These plant ashes were also selected after being taken out of the stove after Ye Hao's special instructions, soaked in water, and filtered with silk.

Now these are ready, and they are already presentable.

Everything is ready, just wait for Ye Hao's order!

"Young master, the things you need are ready, dare to ask what firing method should be now?" Fauber asked.

"You all pour all of this, all lard, grass and wood ashes, into it, and now begin!"

As soon as Ye Hao's order was reached, everyone poured lard and plant ashes into this cauldron, and the two people holding firewood also ignited the firewood, but they saw that a lot of firewood was thrown towards the bottom of the pot.

But I saw that the fire under the pot was burning violently, and after a while, the mixture of oil and plant ash in the pot was boiling, gurgling and rolling, and a thick fishy smell was emitted in the air.

On the surface of the pot, a layer of oil foam also appeared.

"The fire is too small, you go and add some firewood!"

"Well, you go and fetch half a bucket of grass and wood ashes and pour it in."

Ye Hao was constantly commanding, and several family members also added a few more bundles of firewood under Ye Hao's order, and by the way, they also poured half a bucket of grass and wood ash into it.

After continuing to burn for about half an hour, a thick layer of grease has appeared on the surface of the pot.

Ye Hao is overjoyed, it's done?! Ye Hao hurriedly instructed a family member: "You go and scoop out that layer of grease." ”

The housekeeper obeyed the order and hurriedly scooped out the grease with a scoop, "Young master, this is the grease you want, I brought it to you." ”

Ye Hao took a closer look and sighed, this kind of soil burning method has no technical content, but there are still too many impurities on this surface, and then said: "You go find a few coarse cloths and remove the stolen goods in the pot for me, and you, take two pots, young master, I will be useful." ”

……

"Strain the oil out of the pot with a cloth!"

Several housekeepers obeyed the order, wiped the stolen goods in the hot cauldron with a cloth, and then poured out the oil from the pot and filtered it into another cauldron.

Start adding firewood again and ignite this new cauldron!

Ye Hao directly moved his hand and took out a long wooden stick and stirred it in the pot.

"No! Keep burning! ”

……

"No! Give it to me, young master, pour a bowl of wine! ”

"No way!"

After continuing the experiment for half an hour, a thick layer of bright and clear material slowly surfaced on the surface of the boiling grease in this pot.

Ye Hao was overjoyed, and he didn't care about his identity at all, he personally lifted the clean pot and scooped out these bright and clear substances, and his joyful and cautious appearance was like a doll picking up a toy.

When the substances in the pot cooled down, Ye Hao took a long breath!

"Young Master, this ...... What's in there? ”

A family member asked puzzled.

Ye Hao laughed, "This thing, young master, I gave it a fat nickname, called soap!" Hahaha! ”

Everyone was puzzled, and Ye Hao didn't explain, "Little ones, I'm happy today, young master, each of you will come and get a tael of silver, and you can all go down." ”

"Thank you, Young Master Ye."

"Thank you, Young Master Ye!"

Everyone agreed, received the money, thanked one after another, and went down happily with the housekeeper Fubo.

Ye Hao took the knife and cut it into a small boxy piece of soap.

"Let's go, little girl, take the basin and go with me to offer treasure to my mother!"

－－－－－－－－－－－－－－－

Mrs. Ye took the piece of bright and clear soap and said curiously, "Hao'er, what are you?" ”

Ye Hao smiled, "This is soap, and the next thing is the moment to witness the miracle!" ”

Ye Hao put the basin of water brought by the little girl on the ground, picked up the green shirt from the water in front of everyone, wiped it vigorously with soap, and then began to scrub the clothes.

His hands were also full of soap bubbles.

In just a few seconds, this green shirt was washed clean by Ye Hao.

Everyone's mouths widened in surprise, and the shocked expressions were beyond words!

The little girl also looked at Ye Hao with admiration.

"Hao'er, did you make this? It's amazing. ”

"Don't hide it from your mother, it was just invented by the child, this soap can wash the face, bathe, remove mildew and prevent insect moth, sterilization, lubrication... Well, it's pain relief, oil removal, anyway, it has a lot of effects. This soap is the choice of thousands of families, and with this soap, they wear new clothes every day! ”

In the incredulous eyes of everyone, Ye Hao also said what happened just now.

Ye Dashan couldn't help but admire: "I didn't expect this little lard, plant ash, wine and other things to be able to make such a magical thing, it's amazing." ”

Ye Dashan paused, and then said: "This soap is a strange thing, just like what Hao'er just said, over time, it will be able to benefit the people of the world." ”

"I don't know, has my son ever set the price of this soap?"

Hearing Ye Dashan's question, Ye Hao's eyes were full of smiles, and he bent up slightly, like a cunning fox, and replied: "Back to my father, the price has been set, 10 copper plates a piece." ”

After speaking, Ye Hao also raised his two palms and shook them at everyone.

Ye Dashan was taken aback: "What? It's going to be so expensive? ”

"Yes father, 10 copper plates a piece, does father still have any questions?"

"This ...... Do you still feel that the price of this soap is too expensive? ”

Ye Hao shook the white feather fan and said, "Father, since antiquities are rare and expensive, this price is the most suitable. ”

"But... The cost price of this piece of soap is less than 1 copper plate......"

Ye Hao asked rhetorically, "If my father doesn't tell outsiders, how will outsiders know its cost price?" We call it technology, we call it exclusive invention patents, and it is a kind of technology monopoly! Others don't have this product, and of course, they have to buy it with this money! ”

Hearing Ye Hao say this, Mrs. Ye also nodded.

"Then according to what Hao'er said, this thing will be set as 10 copper plates, and it's done!"

Ye Dashan paused, then looked at Ye Hao again, his eyes showing appreciation.

"Hao'er, this invention of yours is good, it is really a charcoal in the snow for our Ye Mansion, with this thing alone, it will not take half a year for our Ye family to become the richest man in the entire Beihai County!"

Ye Dashan is a man with a cheerful personality, and when he thinks of the bright prospects in the future, he is excited, "Hao'er, your confinement, my father has canceled it for you now!" ”

Ye Hao was overjoyed, and quickly arched his hand, "Thank you, father!" ”

"Without further ado, for the sake of my father, I will go to a few partners and talk about this soap and the distribution of profits! Hahaha" After speaking, Ye Dashan left with a loud laugh and a tiger step, Ye Hao could still vaguely hear his hearty laughter from a long distance.

Teach this soap to Ye Dashan to operate, Ye Hao is also completely relieved, this is not only because he is Ye Dashan's son, but more importantly, because although the Ye family is a small family, there is a complete business chain in this drama county, and even in the entire Beihai County.

The Ye family, this touchstone, not big or small, just right.

So, for a long time in the future, Ye Dashan was in a busy state.

Ye Hao also started from this small piece of soap, gradually built his business empire, and used it as a springboard to the road to dominate the Three Kingdoms!
