Shuang Daqin comparison, no comparison, no harm

“Concentrate ore is difficult to mine.”

“Then make fine salt out of coarse salt, no.”

Zhao Ze said calmly.

Coarse salt purification method.

Basically, students with a junior high school degree can master it.

It’s not too simple.

“Coarse salt, can it also be made into refined salt?”

Lees 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 also be made into refined salt?” ”

“Is this really possible? ”

“If someone else says it, I won’t believe it. But what the eldest son Zhao Ze said, then I am sure of it! ”

“The price of refined salt is much more expensive than coarse salt!” ”

“I’m really curious about how the eldest son can make coarse salt into refined salt.” ”

“Our craftsmen in Daqin’s industrial institute are probably busy again. ”

：“…………”

And so it is.

When Ying Zheng heard that Zhao Ze could make coarse salt into refined salt.

Immediately came the spirit.

“A few of you, watch carefully, study carefully!”

He looked at a dozen craftsmen and said.

The craftsmen were all pale.

Boy.

I haven’t remembered how soap does it.

Another coarse salt to refined salt?

That’s a lot of work!

But.

The craftsmen could only nod and answer, “Yes!” Your Majesty! ”

Saw.

pictured.

To validate your own approach.

Zhao Ze took Li Si and Huan Zheng to the kitchen.

“Ze’er, let the widow see.”

“What can you do, turn coarse salt into refined salt.”

Ying Zheng said with a look of anticipation.

Zhao Ze also does not ink.

Grab a handful handful of coarse salt.

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

Technological society, people say coarse salt.

It may be salt that is larger and does not melt easily.

But.

The coarse salt of the Warring States is the salt doped with impurities.

Because the ancients did not understand the technology of separation and purification.

So.

The mined salt, after crushing, is often mixed with sand, dust, these impurities that cannot be dissolved in water.

Eat up.

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

They say fine salt.

It is just salt with no impurities, or few impurities.

Zhao Ze wants to make refined salt.

It will definitely subvert the perception of the two.

Thereupon.

Sprinkle a handful of coarse salt with impurities into the pot.

Turn on fire to heat.

Pour in a little more water.

Just make sure you melt just enough salt.

A moment later.

Under the gaze of Ying Zheng Lisi.

The salt melted into the water.

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

“Ze’er, the salt is gone!”

Ying Zheng reminded.

In his cognition.

The salt is thrown into the water and it disappears.

“Father, don’t worry.”

Zhao Ze was unhurried and found a white hand.

It is a kind of cloth with a fine texture.

Spread the white drapery in a bowl.

Then.

Pour the salt water in the pan.

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

Such.

The salt water then flows through the white drapery into the bowl.

And those grains of sand.

Because the volume is too large to penetrate the white drapery, it is left on the white drapery.

At this time.

The brine obtained is pure and free of impurities.

Subsequently.

Return the brine to the pot and cook over increased heat.

The people of the two worlds stared nervously, not knowing what would happen.

Soon.

Under the gaze of countless lights.

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

At last.

Salt melted into water.

At this moment, it also precipitates, 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.”

Said.

Give the pottery bowl to Yingzheng.

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

This….

Yellow coarse salt, turned into white refined salt?

Lees started first.

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

That salty smell, he was all too familiar.

At that moment, the pupils shook and said, “Great King! It’s really salt! ”

Ying Zheng followed suit, tapped his finger and tasted it in his mouth.

“Yan Xian!”

He said with a bitter face.

However, the corners of his mouth are raised upward.

“After purifying the coarse salt that is difficult to swallow, you can get refined salt.”

“This refined salt is finer than the refined salt we usually eat.”

Zhao Ze is confident.

Hear this.

Li Si finally knew Zhao Ze’s plan.

Sell fine salt!

Fill the treasury!

He said excitedly

“Later.”

“The sale of this salt by the Qin State will definitely make the people willing to pay for official salt.”

In ancient times.

Salt is something that people must use.

Without salt, what is made is difficult to swallow.

In order to fill the treasury, ancient kings would control 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 the price is still expensive.

This salt was called official salt by the people.

See official salt is not welcomed by the people.

Thereupon.

Some businessmen see a business opportunity.

Will secretly mine salt, make salt by themselves, and sell it without the government.

Although discovered, he was severely beaten and distributed to the frontier, and the worst was beheaded on the spot, and the consequences were extremely serious.

Other words.

Ancient salt dealers.

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

Of course.

The profit is about the same.
