Chapter 28 The First Emperor would never allow others to get involved!

Seeing that Jing put it into his mouth without hesitation, and receiving Zhao Si's approval, Wang Li doubtfully picked up a bit of blue-gray salt and put it into his mouth to taste it carefully.

"It's really done!"

Wang Li unexpectedly looked at the green salt in front of him and the black brine salt beside him. He couldn't help but compare and look at it. It was hard to believe that the two were actually the same thing.

"This...what kind of truth is this?"

"How can the lowest-grade brine salt be turned into the finest green salt?"

Zhao Si smiled and said: "Scientific truth."

"Actually, brine salt is not salt. It just contains salt. Salt itself is clean. What I do is filter out the impurities." Zhao Si said.

Can we really say that there are no impurities in salt filtered through plant ash and charcoal? That is impossible, and the quality is definitely not as good as modern table salt.

It's just that the previous brine salt contained impurities in the salt, which caused problems when people ate it. Now after purification and filtration, the salt contains impurities, and there are still some heavy metals, and there are still many impurities.

It’s just that these contents have reached a level that the human body can barely cope with.

"Then... you need to use charcoal fire to bake it? I think it will cost a lot." Wang Li asked.

"That's not true. In fact, you don't need to filter it with cloth. You just need to get some denser sieves to sift out impurities. There is no need to roast it. After sifting, you can filter and purify it with charcoal and plant ash, sift it again, and finally dry it in the sun.

Salt can also be produced by drying. It just requires more manpower." Zhao Si said thoughtfully.

If this thing is to be expanded to large-scale production, it will only require a large number of people to smash the brine salt, then make a large pool and pour it into the fusion, and then use a dense sieve to sift the water, sieve it into the next large pool, and remove the impurities that are insoluble in water.

Filter out.

Repeat two or three times, and the impurities that are almost insoluble in water will be removed. Then use charcoal in the next large pool to absorb pigments and some impurities that cannot be screened out.

Afterwards, it is introduced into the next pond for filtration and purification of plant ash.

Then sift it again and introduce it into the next pool to dry it and produce salt.

Just find an area with abundant sunshine, build five or six large ponds, hire more people, filter and dry them manually, and as long as the weather is good, salt can be continuously produced.

Of course, it’s very expensive!

"Isn't that almost costless?" Wang Li said, ignoring the labor cost.

The more primitive the era, the lower the value of labor and the cheaper the labor cost, which can even be ignored.

It only requires manpower to turn brine salt into a steady stream of table salt or first-class green salt. What a magical skill is this?

"There are a lot of brine salt mines in Guanzhong, so the salt from Qi Di may not be able to be sold." Wang Li looked more excited.

"The brine salt this time still has too many impurities, and the salt yield is a bit low. You can first try to pick up salt from various salt mines one by one, and focus on the brine salt with a high salt yield first." Zhao Si said.

With such filtration and purification, even if a certain amount of loss is caused, a pound of brine salt will not be produced. To put it bluntly, the salt content of the brine salt brought by Wang Li is too low.

"Is this still low?" Wang Li asked back.

"The inedible brine salt can be turned into high-quality green salt, which will be more than a hundred times the profit!" Although Wang Li is simple, he is not stupid.

"How is this a matter of profit?" Zhao Si patted Wang Li on the shoulder.

"You're not planning to let me take a share in it, are you?" Zhao Si asked with a smile.

Wang Li nodded matter-of-factly and said: "You and I are close, my family has its own salt mine, and I will never be greedy..."

Zhao Si waved his hand and said with a smile: "Go back and ask your uncle!"

Salt and iron!

The most important weapon of the country!

This is a new method of producing salt!

What does this mean? It means that large-scale production, no matter in terms of quality or output, can cause a near-destructive blow to various salt-producing lands and reshape the salt division pattern and ecological environment.

Based on what the First Emperor did in history, Zhao Si could even figure out what the First Emperor would do.

Gather manpower and material resources in Guanzhong to find brine salt mines with high salt production rates.

Then concentrate on production, directly deal a devastating blow to the major salt producers in the area, and firmly grasp the salt ecology in your own hands.

In this process, whoever touches it will die.

It is not difficult to guess the thoughts of the First Emperor. In fact, truly outstanding leaders never shy away from letting others guess their thoughts, or in other words, they are often open and honest.

Excellent leaders generally have their own fixed logic of action and do not change their ways easily.

Politics falling into the trap of Machiavellianism is extremely inferior.

This involves the reshaping of the salt ecology and the First Emperor's grasp of the lifeblood of the empire.

How could the First Emperor have any sway in this matter?

It is true that the Wang family is the most meritorious noble in the Qin Dynasty, but the Wang family has no qualifications to interfere in this matter.

All capable emperors and prosperous dynasties will control salt and iron to the end.

This is the undoubted lifeblood of the feudal dynasty.

Not to mention the Wang family, not even the top nobles in Guanzhong put together could make the First Emperor give in.

Wang Li only realized the profit, but ignored what was behind the profit.

Zhao Si had no idea of ​​making salt and steel and selling it for money. Unless it was in troubled times or at the end of a dynasty... otherwise, in the feudal era, no matter which dynasty it was, it would be extremely risky.

Wang Li was a little confused, and Zhao Si did not explain too much, but planned to use the saturated crystallization method to further purify the quality of the salt.

This is very simple. There is a limit to how salt can be dissolved in water. If it is too much, it will precipitate and crystallize.

The solubility of salt does not change very much with temperature.

The remaining elements that are soluble in water either have no solubility at all, or their solubility changes with temperature. Even in a saturated state, salt can be guaranteed to be the first pure crystal to precipitate.

Of course, for salt, a liquid with relatively stable solubility, it is not possible to precipitate pure salt crystals by simply raising and lowering the temperature.

Only the evaporation method can be used.

That is, through artificial heating or natural evaporation of water, the water capacity is reduced and the saturation level is exceeded, and salt crystals will naturally precipitate.

It seems that the principle is the same as boiling water and drying it to produce salt, but in fact it is not.

Drying out salt takes advantage of the fact that salt does not evaporate.

The analysis of crystals by reducing water uses the salt to naturally precipitate and crystallize when it breaks through the saturation limit.

"Wait! Am I stupid?" Zhao Si slapped his thigh, and Wang Li grinned and looked at Zhao Si.

"You took the wrong photo!"

"That's right! That's not the point!"

Zhao Si realized it!

If you use the sun salt method, it is impossible to dry the salt water at once.

It is a process in which the water content continues to decrease and salt crystals continue to precipitate.

In other words, the first crystals to precipitate in a salt water pool are the cleanest salts.

At least it is the cleanest salt in this era!
