Shuang Daqin Comparison, No Comparison, No Harm

"Salt mines are difficult to mine."

"Then use coarse salt to make refined salt, otherwise it's fine."

Zhao Ze said calmly.

Coarse salt purification method.

Basically, students with junior high school education can master it.

Simply not too simple.

"Coarse salt, can it be made into refined salt?"

Li Si asked blankly.

this kind of thing.

is it possible?

Don't talk about him.

Everyone in the original world was also full of surprise.

: "Coarse salt, can it be made into refined salt?"

: "Is this really feasible?"

: "If other people say it, I won't believe it. But what the eldest son Zhao Ze said, then I'm sure!"

: "The price of refined salt is much more expensive than coarse salt!"

: "I'm really curious, how the eldest son can make coarse salt into refined salt."

: "The artisans of our Daqin Academy of Engineering are probably busy again."

: "......"

The same is true.

When Yingzheng heard that Zhao Ze could make coarse salt into fine salt.

Immediately came the spirit.

"You guys, watch carefully and study hard!"

He looked at a dozen craftsmen and said.

The craftsmen all tightened their faces.

Good guy.

What the hell, I haven't remembered how to make soap.

Another coarse salt to refined salt?

The workload is overwhelming!

but.

The craftsmen could only nod their heads and say, "Yes! Your Majesty!"

I see.

on screen.

In order to verify your own method.

Zhao Ze brought Li Si and Ying Zheng to the kitchen.

"Ze'er, let the widow take a look."

"What can you do, turn coarse salt into fine salt."

Ying Zheng said expectantly.

Zhao Ze is not inked either.

Grab a generous handful of kosher salt at hand.

The coarse salt of ancient times is not the same thing as the coarse salt of a technological society.

In a technological society, what people call coarse salt.

It may be salt with larger particles and not easy to melt.

but.

The coarse salt of the Warring States Period was salt mixed with impurities.

Because the ancients did not understand separation and purification techniques.

so.

The mined salt is often mixed with sand, dust, and other impurities that cannot dissolve in water after being crushed.

Eat up.

If you are not careful, you will catch your teeth.

Refined salt they say.

It is nothing more than salt with no impurities, or very few impurities.

The fine salt that Zhao Ze is going to make.

It will definitely subvert the cognition of the two.

then.

Sprinkle coarse salt with impurities into the pot.

Bring to heat.

Pour in a little more water.

Make sure you have just enough to melt the salt.

After a while.

Under the gaze of Yingzheng Li Si.

The salt melted into the water.

Only things like pebbles mixed with salt remained, sinking to the bottom of the pot.

"Zer, the salt is gone!"

Ying Zheng reminded.

In his cognition.

When salt is thrown into water, it disappears.

"Father, don't worry."

Zhao Ze took his time and found a piece of white silk.

Silk is a kind of cloth with fine texture.

Spread the white silk in a bowl.

then.

Pour the salt water into the pot.

Zhao Ze took the white silk out of the bowl again.

so.

The salt water will pass through the white silk and flow into the bowl.

And those grains of sand.

Because it was too large to penetrate the white silk, it was left on the white silk.

at this time.

The resulting brine is pure and free of impurities.

subsequently.

Pour the salted water back into the pot and bring to a boil over high heat.

People from the two worlds stared nervously, not knowing what would happen.

soon.

Under the gaze of countless eyes.

The hot water in the pot turned into mist little by little.

at last.

Salt dissolved in water.

At this moment, it also precipitated, forming a layer of white crystals at the bottom of the pot.

"You're done!"

Zhao Ze used a tool to scrape this layer of white crystals into a clean bowl.

"Father, this is refined salt."

talking.

Give the pottery bowl to Ying Zheng.

Holding the pottery bowl, Ying Zheng and Li Si looked at each other in blank dismay.

this...

Yellow kosher salt turned into white refined salt?

Li Si started first.

Dip a little salt with your index finger and put it in your mouth.

He was too familiar with that salty smell.

Immediately, the pupil trembled and said: "My lord! It's really salt!"

Ying Zheng also followed suit, tapped with his finger, and put it in his mouth to taste.

"Salty!"

He said with a bitter face.

However, the corners of the mouth are raised upwards.

"Use this method to purify coarse salt that is hard to swallow, and then you can get refined salt."

"This refined salt is finer than the refined salt we usually eat."

Zhao Ze has a plan in mind.

hear this.

Li Si finally knew Zhao Ze's plan.

Sell ​​refined salt!

Fill the treasury!

He excitedly said:

"after."

"Qin's sale of this salt will definitely make the common people willing to spend money to buy official salt."

in ancient times.

Salt is something that people must use.

Without salt, the resulting food will be unpalatable.

In order to fill the national treasury, the ancient kings would control the salt, only allowing the government to mine and sell it, and not allowing the people to sell salt privately.

but.

The salt sold by the government is of poor quality and expensive.

This kind of salt is called official salt by the people.

Seeing official salt is not welcomed by the people.

then.

Some businessmen see business opportunities.

They will secretly mine salt mines, make their own salt, and sell it without telling the government.

Although he was discovered, he was severely beaten and dispatched to the frontier, and even beheaded on the spot. The consequences were extremely serious.

In other words.

Ancient Salt Seller.

The risks are the same as those of drug dealers in a technological society.

certainly.

Profits are about the same.
