Daqin: When I return from sea, I will offer you a map of the world

Chapter 29 Our family is not short of money!

As for completely pure table salt, there is no need to think about it at all, it is impossible to do it in this era.

But having said that, in this way, the salt can actually be graded.

For example, the first batch of salt crystals that are naturally precipitated before drying in the sun are of the highest quality.

The more you go back, the more times you go.

The first batch of precipitated salt crystals can be sold as luxury goods.

Salt is a national treasure, but high-quality salt is also a luxury.

For example, the salt used by Wang Li to entertain Zhao Si.

The shape is like a tiger squatting, and even carefully crafted by craftsmen, each piece can be said to be of high value, and it looks quite good on the table.

According to common sense, the first batch of naturally precipitated salt crystals should not contain too many impurities, and the color should be the closest to pure white snowflake salt, rather than the blue-gray color formed by the mixture of various impurities after it is completely dried.

"Get some big pools!"

Just do it when you think of it, anyway, in the Lantian camp, there is no shortage of people.

Wang Li was full of enthusiasm and sent people to help Zhao Si open the pond.

"There is also a sieve, the finer the better!"

Mass production is definitely different from experimentation, and Zhao Si has proposed everything that comes to mind.

The pool alone has directly opened a square pool of six ten feet.

Although Guanzhong is not an important salt producing area, there are not a few brine salt mines that you said earlier that people can't eat them.

Wang Li also sent people to dig out the bittern salt and bring it back...

By the time the pool was opened, it was already dark.

Zhao Si looked at the sky during the day, and it should be sunny in recent days if there is no accident.

The weather for drying salt is good, otherwise it will be bad if it rains.

As for the method of boiling salt, it was popular in Qidi as early as the Warring States Period.

The Qi people, who are facing the sea in the east, have long known the principle of boiling the sea into salt.

However, Zhao Si needs the crystals that are naturally precipitated by the slow evaporation of water, and the sun-dried salt method is also more economical, which is nothing more than looking at the sky.

"However, in large-scale salt production, I am afraid that both sun-dried salt and salt-boiled methods must go hand in hand, otherwise it will be too dependent on the sky. As for salt-boiling, briquettes seem to be able to replace firewood and charcoal!" Zhao Si thought to himself.

In ancient times, the utilization rate of coal was extremely low, but there was not much coal mining in ancient times, especially in the pre-Qin period, there were many open-pit rich mines, and the cost of cooking salt with briquettes was far lower than using firewood and charcoal.

Modern knowledge has produced a subtle linkage!

"It seems that honeycomb coal has to be put on the agenda." Zhao Si said.

In this era, the open-pit rich mines are gone, and the cost of coal is very cheap. After the use of briquette and coal is popularized, it is bound to replace firewood and charcoal.

As for air pollution?I have time-traveled and you still tell me about environmental protection?
Because it is not a small project to make a drinking pool, and the earth needs to be rammed, it cannot be completed in a short time.

It may not be enough to ram the soil once, it is estimated that it will be rammed back and forth several times, then soaked with water, and then continue to ram.

If you don't ram the earth and pour water into it for a while, it will turn into a mud pit, and you will be exposed to the salt of the hammer.

The pond should be large and shallow, and try to ensure the largest sunlight area, so that the salt can be dried quickly.

In a blink of an eye, it was already dark, and several pools had just been dug and tamped.

After that, I have to ram it back and forth a few times. This thing can’t be rushed. It is dried in the sun, soaked in water, rammed into the earth, dried in the sun, soaked in water again, and then rammed again.

There is no way, the salt water is completely soaked without ramming the earth.

"Why don't you say that coastal areas are suitable for drying salt..." Zhao Si scratched his head.

He overlooked a problem. The coastal areas have been infiltrated by sea water for thousands of years, and there are originally many saline-alkali lands.

In some places, it is normal for salt to form on the surface after drying in the sun.

The land in the Guanzhong area is still relatively fertile, and the salt water cannot be soaked up, and the loss will become very large in the process.

Fortunately, it is an experiment, and it does not matter if there is a little more loss.

The night was getting late, and there was no way to continue the construction. Zhao Si was also sleepy early, so he went back home early to sleep.

On the contrary, Wang Lixin had some thoughts about Zhao Si's salt production, and wanted to ask his father Wang Ben, but was afraid of being scolded if he disagreed, so after much deliberation, he decided to go back overnight and ask his father Wang Jian.

Now Wang Jian no longer lives in Xianyang. After Wang Jian conquered Chu, he was extremely close to the state of retirement. As his health has deteriorated recently, he also resigned from his official position.

In short, Wang Jian didn't want to do it anymore and couldn't continue, and Emperor Shihuang probably didn't want to stay anymore.

The two brothers were polite, and Wang Jian went back to the countryside to retire.

Fortunately, Lantian Daying Camp was not located in Xianyang City, so it was relatively fast for Wang Li to pat his horse along the way.

After going through multiple identity checks on the way, Wang Li returned home, and was led by his servants to Wang Jian's house.

Wang Jian was holding a little black dog leaning against the charcoal stove to warm up.

Due to physical reasons, Wang Jian is very afraid of the cold. Even though it has been a long time since spring and the weather is no longer cold, Wang Jian still likes to sleep by grilling charcoal fire at night.

"Is the weather still cold?" Wang Li grabbed the little black dog by the neck and threw it to the ground, then knelt and massaged Wang Jian's calf through the animal skin.

"You're old, your body heats up slowly." Wang Jian narrowed his eyes and said slowly.

Wang Jian is sitting on a jade stool.

This is one of Wang Jian's many trophies. It was something that he had never looked at before, but now it is by Wang Jian's side all day long.

Wang Jian's legs were bad, and he could no longer sit on his knees.

Kneeling, as the formal sitting posture of this era, is actually a rather strenuous task.

"Han Zi" has mentioned.

Jin Pinggong and Tang Yan sat out, uncle Xiang entered, and the Duke dragged his foot.Uncle Xiang asked about it, and the Duke said: "When I was waiting for Tang Zi, his feet were so painful that he couldn't stretch his feet. '

It can be seen that sitting upright is very tiring.

And the seat that assists kneeling is also born naturally.

There are generally two types of seats, one is a small horse that is hidden under the buttocks.

The other is to rely on the feet, the legs are hidden under the feet, and the elbows or hands are supported to exert force, further reducing the pressure on the legs.

As for Wang Jian's legs, even if he used a seat when kneeling, it would not last long.

Now I can only squat on the Hu stool, or lie on the bed.

Wang Jian patted the head of Wang Li who was kneeling beside him, squinting his eyes and speaking slowly.

"Why do you return in the starry night?"

While rubbing his grandfather's legs, Wang Li said, "I'm confused, my friend asked me to go home and ask my father."

Wang Jian was silent, and after a long time he signaled Wang Li to continue talking.

Wang Li hurriedly explained today's events to Wang Jian one by one.

From Zhao Si concocting all kinds of tools, to turning inedible brine salt into high-quality blue salt like turning stone into gold.

When Zhao Si guessed Wang Li's thoughts, he asked Wang Li to ask the eldest father at home.

Old Wang Jian squinted his eyes comfortably, without even opening his eyelids.

"Can't touch, can't touch..."

Wang Jian patted Wang Li on the head.

"Our family is not short of money."

(Push it up, ask for a follow-up, ask for a monthly pass, recommendation ticket, follow-up is the most important thing, readers, masters, please move your little hands, there will be two more chapters a day, slow-paced stories, everyone read slowly. Now The story and the entire social environment of Daqin are still unfolding. I used to write from the lower level to the upper level, but the first time I wrote it from the upper level to the lower level, it really feels different.)
