Chapter 34 Salt Purification Technology

Throttling, it is impossible to throttle, and it is impossible to throttle in this life.

It can only be open source to live.

As for how to open source.

If this were changed in modern society, I am afraid that everyone would be one head and two big.

But this is ancient times, and it was more than 1000 years ago.

It is not easy to make money.

In Li Ming's mind, countless thoughts popped up almost instantly.

What soap.

Papermaking.

typography.

distilled spirits.

There are at least a dozen kinds.

But soon, he quickly ruled out some thoughts.

His eyes fixed on one thing.

Looking at the "salt" written on the straw paper, Li Ming couldn't help showing a smile.

Traveling through ancient times, if you don't get some salt purification technology, it's a waste of time travel.

Especially since he is still in the royal family and is still in charge of the Shaofu, he doesn't even have to worry about selling salt.

Naturally, there is nothing faster than this to make money.

And compared to others, the cost of this thing is the lowest, and it is also the fastest to bear fruit.

As for salt purification technology.

Not to mention that he knew something in his previous life, and even signed in the relevant knowledge before.

It's totally available now.

Soon Li Ming began to search.

He always carries the books he signed in before, and it is not too difficult to find them.

After a while, Li Ming found books related to salt purification technology.

After reading it carefully for half an hour.

Li Ming immediately started to act.

Purification of coarse salt is not overly complicated.

He quickly called a few Shaofu personnel over and started to get busy.

The first is the preparation of tools.

Datang has all of these.

Just prepare a few large pots, as well as gauze, river sand, and charcoal.

Soon, Shaofu prepared what he needed.

In the small courtyard of Shaofu.

Soon it was densely packed with things.

And when all the preparations are done, the work begins.

Or start tinkering.

I have to say that this era is really good. As the superior, he only needs to give orders.

Most of the time, no one will ask why.

Just like this moment, under Li Ming's command, everyone moved quickly.

"Yes, put the gauze on!"

"Yes, add fine sand and charcoal!"

"Stir coarse salt and clean water there!"

The words speak.

Under Li Ming's order, he started to act quickly.

Common impurities in coarse salt include sediment, magnesium chloride, calcium chloride, sulfate, etc.And these are generally divided into insoluble impurities, and the second is soluble impurities.

The first is to use fine sand and charcoal to filter out the insoluble ones.

Then add plant ash, sunlight precipitation, enough to get rid of soluble impurities.

Although after this kind of filtration, the table salt still has some impurities, but it is undoubtedly much better than before.

It is even enough to reach the snow-white refined salt layer.

But in this era, there is a huge difference between coarse salt and refined salt.

Coarse salt is generally less than two hundred yuan per bucket, while the price of refined salt is more than a hundred times.

According to the price Li Ming learned from the Shaofu, the best green salt on the market today is around [-] guan per bucket, and there is no market for it. Twenty or more.

This is no longer a 100% windfall profit, but a [-]% windfall profit.

What's more important is that Shaofu has the advantage of fish and salt, and there is no need to consider whether his doing so will cause any problems.

So the evening came.

When the brine in the pot gradually turned into pure white crystals, the corners of his mouth couldn't help but show a smile.

"It's done!"

The voice of self-talk spoke, and there was excitement in his eyes.

day's work.

It finally worked.

Although there are hundreds of catties of coarse salt, the refined salt produced seems to be less than twenty catties.

However, this value is completely different.

The hundreds of catties of coarse salt used to be sold for at most twenty guan, but now the twenty catties of white salt can be sold for more than four hundred guan.

Although there is no real profit of [-]%, the profit is as high as more than [-] times.

If there is a 20.00% profit, the capital will be ready to move;

If there is a 50.00% profit, the capital will take risks;

If there is a [-]% profit, capital dares to risk hanging its head;

If there is a [-]% profit, capital dares to trample on all laws in the world.

Now it's a [-] percent profit.

Li Ming couldn't help being excited about this.

And he was excited.

And many people present grew their mouths.

"Your Highness, this, this is?"

A servant of the Shaofu spoke with a stammer.

As personal experiencers, their shock is the greatest.

They can say that they saw with their own eyes that the brown-yellow coarse salt gradually turned into snow-white refined salt.

If it weren't for the fact that everything in front of him was so real, he would feel like he was dreaming.

In their cognition, refined salt and coarse salt are basically two species.

Just like divine beasts and ordinary wild beasts.

But at this moment, right under their noses, Li Ming instructed them to gradually turn coarse salt into refined salt.

Even though they were the ones who did all this, everyone still felt a little dazed at this moment.

And looked at the surprised people.

Li Ming also gradually calmed down his excited heart.

Taking a deep breath, he glanced at the dozen or so people present.

"From now on, you will live in these four weeks. This is the secret of the Shaofu. If you leak it, you will be ruined by the Yi tribe."

The words came out sonorously, carrying a killing intent.

"Your Highness, I dare not wait!"

"Your Highness, I dare not wait!"

At this moment, more than a dozen people quickly crawled down and spoke tremblingly. As the "workers" of the Shaofu, they were not so much "workers" as slaves of the royal family.

Betrayal is naturally impossible, and I dare not.

Seeing the reactions of these people, Li Ming nodded.

He is not worried about these people leaking any information.

This is a feudal society, and this is still Shaofu, so it is almost impossible for such a process to be leaked.

But it is still necessary to deter it, so as to avoid any accidents.

After all, in a short time, he still wanted to make a fortune with this refined salt.

Anyway, this is not a fight for profit with the people. Those who can afford refined salt are all rich and powerful, and Li Ming has no psychological burden at all to take their money.

Of course, even if the secrecy effect is really not very good, and it is really leaked, Li Ming is not worried. He has plenty of ways to make money, and this is not bad.

So after being intimidated for a while, Li Ming ignored it and ordered everyone to get busy again.

Bags of coarse salt were brought in, and then quickly converted into refined salt.

When night fell completely, Li Ming extracted more than 50 catties of refined salt.
