The method of Yunshao to purify refined salt is very simple.
First dissolve the salt mixed with a large amount of sediment in water to make a high concentration of brine.
Then filter with linen and charcoal to remove impurities such as mud and sand that are insoluble in water.
Then pour it into a large pot and cook it.
After the water is consumed, what you get is crystalline salt.
The method is simple and the conditions are simple, so the salt obtained naturally cannot meet the level of refined salt in later generations.
This method can only filter out impurities that are insoluble in water. As for soluble impurities such as magnesium chloride and sodium sulfate, Yunchao has no choice.
Of course, the ancients were not fools. The salt they sold had undergone a certain procedure and contained not many toxic impurities. As long as the impurities that were insoluble in water were filtered out, it would basically be no harm to the human body.
The whole process of Yunchao purifying salt is done in front of all his subordinates, and even directed them to do it.
This method has no technical content. To put it bluntly, it is a process of dissolution, filtration and evaporation. People come and go in and out of the house, and they can't keep it confidential even if they want to keep it confidential.
Yun Chao could not do it alone and would not let his boys do it. Could it be that he boiled salt every day?
In fact, the most important thing is not confidentiality, but sales. Without a certain strength, once the government knows about it, it will definitely be done!
Seeing the gray coarse salt turning into fine snowflakes and white salt, the boys couldn't believe their eyes.
In Yun Chao's view, these salts are far from comparable to the refined salts in later generations.
However, the boys have never seen and never heard of!
Even Wang Shitou, who had seen fine salt in the city, was amazed by Yun Chao's ability. In his sense, the fine salt of one tael of silver per pound was slightly inferior to Yun Chao's salt.
A good match!
Lin Youniang and Aunt Wang were so shocked that they couldn't speak, with little stars in their eyes.
Only Yun Chao was a little dissatisfied. The purified salt was not as white as the previous life, nor as fine as the previous life. When I licked it, I always felt that the taste was not so pure.
"Oh, forget it, if you don't have the conditions, just eat it."
Yun Chao sighed sincerely, almost not making the others angry.
In other words, everyone doesn’t know what it means to show off, otherwise they will definitely give Yun Chao a middle finger and then give him a name called Old Versailles!
Your salt is so fine that it is still enough to eat it. If this is not a show of pretentiousness, what is a show of pretentiousness?
"Come on, don't be polite, everyone will pack two pounds each when you go home tonight, so that your family can also try it."
Yun Chaogao was unexpectedly favored, but was opposed by Wang Shitoudi.
Others have no knowledge, and stones are different. He and Yun Chao bought salt when they entered the city and knew how expensive the fine salt is.
"Second brother, I don't want it. This is better than a tael of silver per pound of salt in the city. I don't eat it. If I eat it, I will lose my blessings!"
The reason why Yun Chao trusts Shit the most is because he knows the importance of it, knows what he should want and what he should not take, and is also the most loyal.
In fact, Yun Chao didn't really value these salts as much.
If others sell more, they may not be able to sell more.
The key is sales. No matter how good the thing is, it won’t be worth much money if it’s sold.
After hearing Yun Chao say that everyone should take salt home, the boys were very happy.
But when Shi Tou heard that the salt in the city that was not as good as Yun Chao could be sold for one tael of silver per pound, they were all numb, and they refused to ask for it no matter what they said!
Just kidding, people even said they didn’t want it, but they still wanted it. Doesn’t this seem to be ignorant of the importance of it?
Finally, Yun Chao gave the order, and everyone took half a pound each.
There are more than 100 kilograms of refined salt, and every boy is nothing to give him half a kilogram.
If you really can find a safe sales route, the cheap salts in the city with poor quality are more, just buy them and purify them yourself, as much as you want.
When Wuchao people sell things, they usually use oil paper to wrap them in sacks of private salt. There are a lot of this oil paper, which is just right in hand.
After dinner and when the boys came home, they held half a pound of salt in their hands, which was even more careful than on wedding night!
Of course, it was their parents’ wedding night, not their own, and the kids’ wives were still hidden in some corner.
However, now with Yun Chao, all the boys believe that their good things will come soon. As long as the family life gets better and better, why worry about not being able to find Xinyi’s little lady?
Wolong Village was sensation again.
"What? Yun Er actually gave each of his boys half a pound of salt?"
"What, Yun Erfa is the fine salt that only those noble people in the city can eat?"
"What, Yun Erfa's salt costs one tael of silver per pound in the city?"
"What? Yun Er's salt is better than that kind of refined salt? You can't buy a pound of silver or a pound?"
"Take it down, who believes it!"
"Yes, whoever loves to believe, I don't believe it anyway!"
“…”
However, facts are better than words, and the salt from Yun Chaofa is placed there, whether you believe it or not, it is there.
When the questioning villagers ran to see them, they all fell silent.
Whiter than all the salt you've ever seen!
Thinner than all the salt I've ever seen!
I don’t know if a pound is worth a tael of silver, but I have never seen it before.
Not only have I never seen it, I haven't even heard of it!
After hearing about it, Lai Zhicheng's sister-in-law also went to see it.
As soon as I got home, I started chattering and talking vividly.
How white is Yun Er's salt?
How thin is Yun Er's salt?
How beautiful Yun Er’s salt is...
The more I talked about it, Lai Zhicheng's sister-in-law became more excited, and her face was filled with seductive charm, as if she was just married, and Lai Zhicheng swallowed his saliva.
While swallowing, Lai Zhicheng was angry.
My sister-in-law opened her mouth and shut up Yun Er. Can you say something else besides Yun Er?
Yun Er!
It's Yun Er again!
Did you guy send me to oppose me?
First, I lost all my face, but now I robbed my sister-in-law. You deserve to die!
Unfortunately, Lai Zhicheng's sister-in-law was in excitement and did not notice how ugly her brother-in-law's face was.
"Sister, brother-in-law, why don't I go to Yun Er to talk to you, and let's get some salt back and taste it?"
Lai Zhicheng's nose was almost skewed, and the wound on his body suddenly started to hurt again.
"Hmph, do you think that boy Yun Er will give it?"
Lai Zhicheng's sister-in-law curled her lips in a charming way: "He dares! But if he doesn't give it to us, we can buy it..."
Lai Zhicheng could no longer help it and pointed at the door: "Go out, go out for me!"
Lai Zhicheng's sister-in-law has never been so angry. Her brother-in-law, who has always been kind to him, dares to rape him. Humph, go out when you go out, and people go to find Yun Er to find a way to taste his taste...
