Chapter 33 Salt Purification Technology(1/2)

 It is impossible to reduce expenditures. It is impossible to reduce expenditures in this life.

I can only live by open source.

As for how to open source.

If this were to be the case in modern society, I am afraid that everyone would be one head and two heads above the others.

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

It’s not easy to make money.

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

What soap.

Papermaking.

Typography.

Distilled liquor.

There are at least a dozen kinds.

But soon, he quickly eliminated some thoughts.

His eyes were fixed on one thing.

Looking at the word "salt" written on the papyrus, Li Ming couldn't help but reveal a smile.

Traveling through ancient times, if you don’t get some salt purification technology, it would be a waste of time traveling.

Especially since he is still a member of the royal family and is still in charge of the young master's office, he doesn't even have to worry about selling salt.

Naturally, there is no faster way to make money than this.

And compared to others, this thing has the lowest cost and the fastest results.

As for salt purification technology.

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

Now you can take advantage of it.

Soon Li Ming began to search.

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

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

After reading carefully for half an hour.

Li Ming immediately started to take action.

The purification of coarse salt is not too complicated.

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

The first step is to prepare the tools.

These were all available in the Tang Dynasty.

All you need is a few large white pots and gauze.

Soon, the young master prepared what he needed.

He is in the small courtyard of the Shaofu.

Soon it was densely packed with things.

And when all preparations are completed, the work begins.

In other words, I started to tinker with it.

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

In most cases, no one will ask why.

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

"Yes, put the gauze on it!"

"Yes, add fine sand and charcoal!"

"Stir the coarse salt and water there!"

Words speak.

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

Common impurities in coarse salt include sediment, magnesium chloride, calcium chloride, sulfate, etc. These are generally divided into insoluble impurities and soluble impurities.

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

Then add plant ash and let it settle under sunlight, which is enough to remove the soluble impurities.

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

Even enough to reach the level of snow-white refined salt.

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

Coarse salt generally only costs about two hundred cents per bucket, while refined salt is more than a hundred times more expensive.

According to the price Li Ming learned from the Shaofu, the best green salt on the market today is around 100 guan per bucket. There are still prices that are unmarketable. Even the second-grade white salt is only 100 guan per bucket.

More than twenty strings.

This is no longer a 100% huge profit, but a 10,000% huge profit.

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

So when dusk falls.

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

"It's done!"

He spoke in a self-talking voice, and there was excitement in his eyes.

A day’s effort.

Finally succeeded.

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

However, this value is completely different.

In the past, hundreds of kilograms of coarse salt could be sold for around 20 kilograms at most, but now these twenty kilograms of white salt can be sold for more than four hundred kilograms.

Although there is no real profit of 10,000%, the profit is as high as more than 20 times.

If there is a 20% profit, capital will be ready to move;

If there is 50% profit, capital will take risks;

If there is a 100% profit, capital will dare to risk hanging;

If there is a 300% profit, capital will dare to trample all laws in the world.

Now it’s a 2,000% profit.

Li Ming couldn't help but be excited about this.

And he was excited.

Many people present were speechless.

"Your Highness, this, this is?"

A servant of the Young Mansion spoke with a stutter.

As those who have experienced it personally, their shock is the greatest.

They can say that they saw with their own eyes that the brownish-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 have felt like he was dreaming.

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

Just like mythical beasts and ordinary beasts.

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

Even though all this was their fault, everyone still felt a little dazed at this moment.

And looked at the surprised people.

Li Ming also gradually calmed down his excitement.

He took a deep breath and glanced at the dozen or so people present.

"From now on, you all will live around here. This is the secret of the Shaofu. If you let it out, the three Yi tribes will suffer."

The words came out sonorously, with murderous intent.
