When Lu Si went to fetch the filtered gauze and sieve that Mo Shu wanted, several of the guards did not look very good. In their opinion, Mo Shu's move is deliberately tossing people and delaying time.

Mo Shu didn't pay attention to the guards' faces, and saw that everything was ready, so they first filtered out several large buckets of spring water of different colors.

Unexpectedly, Mo Shu also supported Lu Yi and them to work, Wu Ziheng was a little surprised.

Although Lu Yi didn't think that Mo Shu could really cook salt, they saw that their master did not object, although they were unhappy in their hearts, they also acted according to their words without the slightest hesitation.

Mo Shu was very satisfied.

Wu Ziheng watched from the sidelines, and saw that Mo Shu commanded Lu Yi and a few people quite calmly, with a bit of everyone's demeanor, and couldn't help but sigh that it was a family that had been inherited for thousands of years, and the heritage was still there. He didn't know at all that Mo Shu was not doing this because of the Mo family style in Lingbei.

If she had changed to the original Mo Shu, she wouldn't know anything at this age!

After a few guards filtered the spring water, they looked at Xiao Jing with a relaxed face and talked to Xiao Jing about how to filter Mo Shu better, and asked in a deep voice: "Miss Mo Liu, the salt brine has been filtered properly, what should I do next?" ”

Mo Shu walked over, looked at the filtered brine in the bucket, nodded and said, "There are a few workers, and go to the side to rest first, and I'll take care of the next things." ”

However, after she said this, several of the guards stood still, trying to see what she could do.

Xiao Jing also rushed closer to Mo Shu's side.

Mo Shu naturally didn't drive people away, took the water scoop and started working.

A few guards saw that Mo Shu first scooped a few spoonfuls of black spring water with a scoop and put it into a large wooden bucket, and then scooped a few spoonfuls of yellow-brown spring water into it, and then evened it out, and after waiting for a while, she dipped a little of her finger into her mouth and nodded.

Xiao Jing couldn't hold back his curiosity, and he also mustered up the courage to follow Mo Shuxue, put his finger in his mouth, his eyes lit up, and he laughed out two shallow pear vortices: "Sister Mo, it's salt!" ”

Mo Shu smiled and nodded.

When several guards heard this, they immediately learned from Mo Shu's appearance, and dipped their fingers in a bit of brine spring to taste, and the salty taste melted on the tip of the tongue, although there was still a bitter and astringent taste, but even if the spring water was filtered before, it was still so bitter that it was almost impossible to eat the salty taste.

Lu Er and the others were ecstatic, they couldn't believe it. Lu Yi asked blankly, "Miss Mo, are you ...... How did you get it? ”

Wu Ziheng has been sitting in the tent eating tea leisurely, and he doesn't seem to take the matter of boiling salt to heart, but in fact, he is paying close attention to the situation on Mo Shu's side.

When he saw Mo Shu dip his finger in the strangely colored spring water and put it in his mouth, he couldn't help but twitch the corners of his eyes.

Then I saw Xiaojing painting the gourd in the same way, and I tasted it the same, and I almost couldn't help it. Can you eat it so dirty? But Xiao Jing's words immediately shocked his heart and made him a little hard to believe.

Two words, like the voice of a saint: it's salt!

Mo Shu really got the salt?!

Wu Ziheng has seen a lot of wind and waves, and it is impossible for him to be like a few guards, stupidly using his fingers to try the dirty brine, so he still sits like a mountain, and the clouds are light and the wind is light.

However, Lu Yi asked Mo Shu in a daze: "Miss Mo, how did you get it?" ”

Wu Ziheng couldn't sit still, Lu Yi's stupidity simply made him lose face, he turned his head and asked coldly: "Lu Si, what did you see?" ”

Lu Si glanced at Lu Yi, and scolded him in his heart, but replied respectfully: "Lord Hou, according to what Fang Cai's subordinates saw, Miss Mo first scooped four scoops of black brine and put it into the bucket, and then added six scoops of yellow-brown brine, then stirred the water well, and after waiting for a while, the color of the mixed water in the bucket became lighter, and I tasted it with my fingers, and the bitter and astringent taste had disappeared for most of it, and the salt taste became particularly obvious. ”

Wu Ziheng Yuguang saw the surprise on Mo Shu's face, and he was satisfied, but he said lightly: "It's okay." ”

Lu Si, who thought he was going to be angry and scolded, became happy.

And Mo Shu's surprise is not fake, in her usual impression, the guard Lu Si looks like a tiger's waist, copper muscles and iron bones, and his temperament is also very straightforward, thinking that he is a rough person, but he didn't expect it to be thick and fine, and she remembers her movements clearly and understands, and she also has the know-how.

Lu Si only needs to do what he said, and he can completely get the same salt brine, and the salt boiled out of this brine is already edible.

I saw Lu Si ask Lu Yi proudly: "Do you know now?" ”

Lu Yi nodded awkwardly and said, "I know, but my subordinates don't understand, why does Miss Mo mix two different brine like this, and the impurities in it are gone?" ”

Wu Ziheng looked at Mo Shu and said, "Let Miss Mo laugh, my subordinates are really a little stupid." ”

Mo Shu blinked and said, "Marquis Zhenyuan's words are serious. ”

Wu Ziheng said very modestly, but his posture was still light and calm, and he still looked high, but when you saw him, you would feel that it should be so.

All mortals are dust in the face of the gods. Mo Shu thought to herself. She smiled, "I was trying to get a couple of people to pour the brine from this barrel into another empty barrel......

Before Mo Shu finished speaking, Lu Si had already strode up to her, easily lifted the bucket, and was about to pour it into the empty bucket next to her, but heard Mo Shu shouting: "Slow, wait a minute!" ”

Lu Si moved too fast, and Mo Shu was worried that he would not have time to stop it, but seeing that he was holding the bucket steadily, he turned his head and asked strangely, "Didn't you say that you were going to pour the water over?" ”

OK.

Mo Shu glanced at Lu Si's strong arm with appreciation, and asked Lu Yi and Lu Er to cover the mouth of the empty bucket with several layers of gauze to filter before saying, "You pour slowly, don't pour the things deposited at the bottom of the water into it." ”

Lu Si poured the water over.

When the brine was almost dry, he saw a layer of white deposits at the bottom of the barrel, Lu Si steadily put the barrel back again, and said happily: "Miss Mo, is this salt?" ”

Mo Shu shook her head and smiled: "It's those harmful things, you can't eat them." ”

When Lu Yi heard this, he couldn't help but ask: "It's just that by mixing the two brine together, these things can be separated from the brine?" ”

Seeing that everyone looked humbly seeking advice, Mo Shu smiled slightly: "My master said that this is because the harmful substances contained in these two different brine are mixed together, and they will react into a white precipitate underneath, but as for why such a reaction occurs, I don't know." ”

Several guards suddenly exclaimed: "That's it! ”

After being happy, Lu Yi asked suspiciously: "I don't know who Miss Mo's master is, since he knows this method of mixing salt and brine, why have he never heard of it before?" ”

If there is such a master, it must be more than just the method of frying salt?

Wu Ziheng also raised his eyes and looked over.

Seeing that everyone didn't seem to believe it, Mo Shu took out the story that had not yet been made, and said gloomily: "When I was a child, I lived on the streets with my sister, begging everywhere ......."

The principle of halogenation:

The skirt is a method of making salt with reference to well salt. The raw material of well salt is brine, which is divided into two types: yellow brine and black brine, yellow brine is a brown solution, which contains a large number of barium ions, and the salt boiled with it is bitter and toxic; Black halide is a black solution, which contains a large amount of sulfate ions, and is also a kind of substance that is not good for the human body. Our industrious and intelligent working people have found that if the yellow brine and black brine are blended together in a certain ratio (generally the yellow brine is 7:3 or 6:4 than the black brine), the barium ions and sulfate ions will combine to form a white precipitate (that is, the method of modern chemical testing of sulfate, the barium sulfate white precipitate: BaCl2 is converted into Baso4 and precipitate), and then the precipitate is removed, and these harmful substances in the brine can be removed.

The skirt has to sigh that our smart and capable working people are potential chemists and physicists!
