In ancient times, there was fine salt, and the salt was ground into minced pieces, which was the so-called fine salt, but it was certainly not refined salt. In fact, whether it is boiled salt, lake salt, or well salt, they all belong to coarse salt.

Even many salts contain some toxic substances in them.

In addition, some salts contain potassium salts and magnesium salts, which have a bitter taste, different minerals, and different tastes, so green salt is delicious, which is precisely the reason.

Professor Wang Ju's method is very simple, that is, the coarse salt is re-melted, the alkaline surface is added, the excess calcium chloride and magnesium chloride are removed, and the multi-layer gauze is repeatedly filtered to filter out trace sediment and sediment, and then steamed and crystallized, which is the so-called refined salt.

Of course, this method is not standard, first the alkaline surface is not pure sodium carbonate, even if it is pure sodium carbonate, then barium hydroxide must be added to precipitate sulfate and residual magnesium ions, and finally dilute hydrochloric acid is added to adjust to neutral, which is close to the standard refined salt.

Or add sodium chloride dropwise to remove sulfate ions, then add barium hydroxide dropwise to remove magnesium ions, add sodium carbonate to remove excess barium chloride, add dilute hydrochloric acid dropwise to neutralize, and then filter and evaporate crystallization.

But how is this possible under the present conditions?

The quality of salt can only be improved by this simple and crude method, and it is a big deal to dissolve and filter and steam several times. There may be a better way, but Wang Ju really doesn't know.

It's not a few pieces of money, in order to finally make it out and get the best plan, the Zhu family spent more than 50 costs.

Zhu Huan used his fingers to dip a little salt and put it in his mouth: "Good salt, delicious taste." ”

What exactly is delicious? The light taste can make some special dishes of Cantonese cuisine scared like earth, and Cantonese people will avoid the soy sauce braised in Anhui cuisine, Jiangsu and Zhejiang people will regard the spicy Sichuan cuisine as a heavenly fire, and Sichuan people will vomit more than the thick sugar in Jiangsu and Zhejiang......

The actual coarse salt should be heavier and more salty than fine salt and more stimulating to the taste buds.

But it's fine, like the end, it melts when it touches the mouth, and it has been filtered repeatedly, although it is still mainly boiled salt, but after repeated filtering and steaming, it has become extremely good-looking.

Snow white, as clean and lovely as snow.

The cost is a bit high, but it's worth it, Zhu Qing asked fixedly, "How much is it worth a pound?" ”

God knows.

"Remember, don't give away the recipe."

In fact, the cost is high, and the method of making zuò is not very difficult, and some proportions can also be molded out. Scarcity is expensive, and once it leaks out, it is worthless

Zhu Huan looked at the pile of salt and pondered.

In the Song Dynasty, luxury goods began to appear, not only pearls and jade, but also luxury items for daily necessities, such as a meal in Fanlou, as little as a few hundred taels of silver, and as many as a thousand taels. For example, the Xia State Sword and the high-grade Western Xia crossbow are also calculated in hundreds.

"How much can this salt sell for?"

Obviously, it is another huge wealth, Zhu Huan thought for a long time, suddenly stood up, and went straight to the Li family with some fine salt.

"Li Yuanwai, look." Zhu Huan opened the salt packet.

"What is this?" Concubine Li's father didn't even see that it was salt.

"Taste it."

"Salt." Li Yuanwai stood up: "Where did it come from?" ”

They are all businessmen, and they can see its value at a glance.

"Ordinary salt can be processed into this salt."

"How much does it cost?" Li Yuanwai looked at Zhu Huan with a blank eye, clearly saying whether I could get involved in this business.

"Regardless of the cost, it was taught to me by your son-in-law."

"Zhu Yuanwai, are you kidding me...... You mean the kid. ”

"Great, there's something I can say to you." Zhu Huan probably talked about the things that happened in the past year, but the private goods on Heiao Ridge were said to be the fur of medicinal materials, and Wang Ju could not be stained with private salt by life or death, in case he could roll the name Donghuamen, this resume would pit Wang Ju.

"Zhu Yuanwai, why are you so enthusiastic?"

"If it were you, would you be enthusiastic?"

Li Yuanwai smiled bitterly, the nature of the two is different, what the Zhu family has paid is just some money, and it seems that the Zhu family has already paid off this money, not to mention his second son's enlightenment. What he paid was his daughter's lifelong happiness.

After thinking for a long time, he said, "Let me ask the concubine." ”

…………

Where the second uncle is sitting is still sleepwalking, the distance between the Li family and the Wang family in Yanzhou City is no less than the distance between Zhao Zhen and Wang Ju in Wang Ju's heart.

And there was no news about the Zhu family before, so that after he heard the news, he stayed for several days.

Mother Li smiled and shook her head.

The same rice, a hundred kinds of people.

One is an uncle and the other is a slave (nephew), but now it seems to be reversed.

She looked at Wang Ju and asked, "Little brother, why do you have to make three requests?" ”

The three requirements are not excessive, and in the end the Li family is somewhat displeased, no matter how promising you are in the future, now my family is higher than your family.

Wang Ju replied calmly: "I still have younger brothers and sisters, so it is not appropriate to be rich, and I am also poor now, although the Zhu family intends to sponsor me, I am a scholar, there is no need, and I don't want to be favored." As for the delay of family affairs, there are two main ones, the first is that my younger siblings are relatively young now, and they will gradually grow up in a few years, and I am determined to be in Keku, but it is too difficult to get ahead, and I must study with peace of mind. Secondly, the female university has changed eighteen times, and the male university has also changed eighteen times. In case I become unscrupulous in the future, your family can also regret the marriage, and it will not hurt Little Lady Li. ”

"What if you roll call Donghuamen?" Li Mu asked.

The arrest of the son-in-law under the list is too fierce, as long as he can be caught, whether it is an old man or not, he will desperately drag him home.

At least one-third of the Jinshi were captured by large families in the Central Plains.

What will be the role of a marriage engagement?

"That's not going to happen, it's too difficult to roll name Donghuamen. At least before the crown, I'm afraid I didn't have that knowledge, let alone that unrealistic idea. My idea is to see if I can become a lifter before I win the crown. Then study those scholars, one test, two tests, three tests......"

Li Yuanwai was happy.

"So what are your plans for the next few years?"

He didn't talk about that big truth like Wang Ju, but it's almost, no matter the first, second, or third exams, if you can pass the exam, there will be green smoke on the Wang family's grave, and even Yanzhou will be a sensation, poor Yanzhou, there is no Jinshi yet.

But for now, I have to live.

"Li Yuanwai, that salt......" Zhu Huan sat on the side and whispered. If you can make a profit, should you really forget about Wang Ju? Of course, there is no sales yet, and Zhu Huan will not talk to Wang Ju in detail, let alone how much profit will be generated. Besides, there is Xia Guojian who can get dozens of times a year.

The next sentence is not very easy to say, after the hairpin, your Li family really ignores this son-in-law. With a three-pronged approach, can't the life of Wang Ju's brothers and sisters be guaranteed? Will your daughter still suffer? Besides, Wang Ju is still growing rapidly, and when he reaches the age of twenty, only God knows how far he has grown.

Wang Ju is not angry, the consideration of parents must be long-term, is it because of their daughter's temperament, let her marry a beggar or a gangster.

This is not snobbery, but love for children, what is snobbery, that is pure dislike of poverty and love of wealth, then he would not be able to sit here today.

Wang Ju replied calmly: "I also said in the village that letting them control the output of Xia Guojian is actually a matter of how much effort to carry a heavy burden. I'm still young, so I just need to have enough to eat. I can't think about it for the time being, but learning is the key to me right now. ”

He was going to worship Zhang Zai as a teacher, but he didn't say anything.

That's not going to be an ordinary student of Zhang Zai, if that's the case, Zhang Zai shouldn't have too many disciples.

But if you want to become Zhang Zai's personal disciple, you must have the knowledge you can handle, not the knowledge of his previous life, but the knowledge of Jingyi poetry.

In this regard, at least his foundation is still relatively poor, but most of the officials of the Song Dynasty are grinding and surveying systems, and Zhang Zai will be transferred to Weizhou after staying in Yunyan County for more than three years at most, so can he go to Weizhou to study. So this time must be achieved at the end of this year or next year's New Year's Day, the sooner the better. But if you want to be early, you have to study hard.

This is the hairpin.

After the grass post is detailed, the parents of the men and women meet, and the men and women themselves also have to be present, which is actually a blind date, if the man is not satisfied, take out two colored forges to the woman to suppress the shock. If he is satisfied, the man takes out a golden hairpin and inserts it on the woman's head, which is the label, and it is the man's person. Of course, there are many etiquettes behind, but this is not in a hurry, and the two sides can discuss early or later.

But before inserting hairpins, parents on both sides will also communicate.

Wang Ju has parents, but the people of the Jiang family can't come, so they have to let the second uncle replace him. Then there are Li Yuanwai and his wife, as well as Concubine Li, Zhu Huan and the matchmaker.

Li Yuanwai and his wife glanced at each other, and Wang Ju spoke freely and was quite satisfied. Besides, Wang Ju also said that there are still six years, and he can regret his relatives if he is not good, of course, this is a kind of self-confidence of Wang Ju. So what else to say?

The two nodded.

Zhu Huan immediately said: "Xiaolang, don't you want to insert a hairpin?" ”

Wang Ju took out a golden hairpin and stuck it into Concubine Li's head, looking at Concubine Li'er's happy face, although it was an engagement, he still had some guilt in his heart, so the hand kept trembling.
