Zhu Biao studied since he was a child and was educated in Confucianism.
Reacting now, I dragged the boxes and opened them one by one.
"The prefect of the Song Dynasty wrote to Hai'er, asking the village to give one thousand soaps to the palace and one hundred soaps to Ningguo Mansion.
Another five thousand soaps were sold to the palace for two hundred coins each.
He also said that soap requires oil. If you are trading with foreigners, ask for as much oil as possible..."
Zhu Biao explained to his parents that the price was 500 coins a piece in Xuancheng and 700 coins a piece in Nanjing.
Give it to the palace for wholesale, two hundred coins, and the palace will take out the food. Remember to have oil.
This soap is made from oil, and the oil is edible.
"Chongba, that person is testing us."
After listening to her son's words, Queen Ma thought of many things in an instant.
Zhu Yuanzhang agreed: "He wanted to see what we wanted to do. He said it was for the palace, then mentioned foreign trade, and finally said oil."
Empress Ma answered: "Should we change the oil? If we change it, we will follow his arrangement. If we don't change it, what will he think?
We can't buy a piece of soap from him for four hundred cents and sell it in Daming, and make money in Daming for five hundred cents, right?
According to this person's idea, let's buy soap from the village for 200 coins and sell it to foreigners at a higher price to change the oil. "
Zhu Biao felt aggrieved when he heard this. A soap maker had to force and test his own parents?
"Mom, can't we go over and tell them in person? There's a layer between us, so no one will believe anyone."
Zhu Biao did not choose to arrest the person. He wanted to go over and see the master and talk to him in person if there was anything he wanted.
He didn't know yet that they had never considered temptation or persecution, it was just inconvenient to show up.
"Don't worry, ask foreigners first to see how much they are willing to pay. Just like rock candy, foreigners are not allowed to sell the same thing in Ming Dynasty."
Queen Ma looked at the soaps stacked in the box and was in a good mood.
What Ming Dynasty sold to foreigners, foreigners were not allowed to resell to Ming Dynasty because the price was lower than the retail price.
"Buying oil, at what price the oil was sold to the village... Huh? Their surname is Zhu too?"
As Zhu Yuanzhang spoke, he remembered the main surname in Xiaqiu Village. The head of the family was named Zhu, and his name was Zhu Yichang.
"I said, who is so capable and can get guidance from an expert? He is a member of our Lao Zhu family.
I guess the people behind it thought so too, and showed it to us through the village named Zhu. "
Zhu Yuanzhang found another support point and made up his mind.
A family of three is in a good mood when eating, and the food looks delicious.
Zhu Biao accompanied his father to drink, and Zhu Yuanzhang drank a small cup: "In the past, we obtained more jewelry, silver, gold and medicinal materials from foreigners, and we had to add oil.
This oil... How much oil does it take to make a soap? How much does the village earn from a piece of soap worth 200 yuan? "
He began to calculate the village's production costs. If one hundred pennies of oil was used to make a piece of soap, wouldn't the village earn twice as much?
"Two taels for a piece of soap, it's not much, I think, I can make ten or eight cents."
Zhu Biao thought that it was so expensive to sell it elsewhere, so if he paid the palace a price of 300 cents, the profit should not be too high.
Queen Ma glanced at her son: "When rock sugar sells for four hundred cents, who would have thought that the price of brown sugar is so low? Maybe soap can earn fifty cents."
"If you earn fifty cents, you will earn fifty cents. Bingtang has robbed him. If he makes money, isn't he also buying livestock and meat for the village?"
Zhu Yuanzhang was generous and gave him fifty liters of profit.
The three of them had no idea how to calculate the cost, only Zhu Wentian understood.
It depends on what oil is used. The saponification value of different oils is also different.
Then you will know how much stone soda to use. Stone soda depends on the labor cost and the surface cost.
Add the cost of salt and spices to it, and finally the cost of the entire soap is calculated.
The village uses rapeseed oil, and the saponification price is 0.124. One gram of oil requires 0.124 soda ash, and the soda ash is not pure enough.
Water is added to it, and water also plays a role.
How much water to add can be calculated by the amount of soda ash, but it is not pure and can only be calculated by the weight of the oil, which is about 40%.
The price of rapeseed oil ranges from twelve to sixteen cents per pound, and the prices vary in different places.
In some places where rapeseed is not grown, it will be even higher.
When the rapeseed harvest season comes, the price of rapeseed oil will be low.
After comprehensive calculation, the cost of a piece of soap is 3.7 cents, including the labor cost, it is 4 cents.
The cost of soap without fragrance is 1.80 cents, which can buy two kilograms of shelled rice.
The spices bought there are expensive. Next year, Zhu Wentian plans to mix his own spices, such as getting essential oils from various flowers and dry distillation.
Coupled with the expansion of scale, better tools are manufactured, and the cost is further reduced.
But the ones with essential oils are not at this price, and it takes a lot of flowers to get a little essential oil.
It seems like a simple saponification reaction, but Zhu Wentian calculated a lot of data to reduce the cost of trial and error.
…
"Bubble, bubble, um! Hey hey hey!"
Another day in the morning, the villagers killed the pig first under Hanhan's command. The pig blood was not used for food, but was put in the pot.
Four fishing nets are soaked in it. This is called a blood net. The nets of hemp and cotton soaked in pig blood and steamed can keep them from rotting for a long time.
The net also smells like pig blood, which can attract more fish.
The two fishing nets were new, leaving behind a boat about two feet long, with four fishermen working on it.
The four people were not happy at first. One month was a free month, and if they didn't come, they would have to pay for food.
Zhu Wentian didn't want to see the black face for a month, which would affect his mood.
The boats were idle and wasted there, and the people hired to transport things to Nanjing were not responsible for fishing.
If you force them to do it, they will have to agree, and they will not contribute any effort!
The head of the village discussed with four people and gave each person three kilograms of rice a day, three meals and a place to live.
The other party needs to obey the village's instructions, such as fishing.
I also bought a new fishing net from one of their families, who had it in stock.
They were given food for thirty days at a time, sent a car to take them home, and picked up fishing nets at the same time.
The fishermen happily agreed, is there such a good thing? made money.
Today they helped to bleed the net together, and at the same time they learned a trick, soaking the net in pig blood to see if it was good.
If it works, go back to your own home... Pig blood is difficult to get, it depends on who kills the pig to get it, or replace it.
The villagers firmly believe in Hanhan. The village guard says it can be done and must do it.
After the blood is finished and the net is hung up to dry, it's lunch time.
The four people looked at the food and felt uneasy. A man named Zhao Li came to the table of the chief: "Chief, when will we fish?"
"The fishing net will be drying for two days." The manager reminded the other party that the net had just been steamed.
"Is there any other work?" the man asked again.
"Eat first, then talk after eating." Li Chang understood that the other party saw that the food was good, so he would feel guilty if he just ate without doing anything.
"Oh!" Zhao Li went back and repeated it to the other three companions.
The three of them sighed and lowered their heads to eat.
The manager looked at Hanhan and said, "You can save money on fishing to buy fish to eat. Fishing with ropes is getting more and more difficult now."
Zhu Wentian grabbed a pig's trotter and gnawed it. He chewed it with his mouth and made a humming sound from his nose.
"Are you going to catch crabs to sell this year?" The manager said about fishing, and then thought of crab baskets.
Last year's fishing and crab sales were an emergency for the village.
Zhu Wentian swallowed the food in his mouth: "Catch, ah! Eat, basket, borrow, eh! Ugh!"
"Lend it to villagers in other villages and teach them how to make crab baskets, hey hey hey hey!" the village chief said helpfully.
"Yeah!" Zhu Wentian nodded and continued eating.
