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

Chapter 27 This is clearly a stone!

Wang Li's movements were quick, and he got inedible salt in a short while.

Zhao Si fell silent when he saw the stone in Wang Li's hand.

"I asked you to bring the salt." Zhao Si said.

"Yes, isn't it salt that cannot be eaten?" Wang Li was full of doubts.

What he brought was inedible salt, stones mixed with salt crystals, or simply salt stones licked by animals in the mountains.

"Is there any problem?" Wang Li asked.

"It's inedible salt, but is it possible that it's rocks and not salt?" Zhao Si asked.

"Brother, this is salt!" Jing whispered from the side.

Zhao Si was taken aback for a moment, and questioned all over his face: "Can this be called salt?"

This is clearly a stone!

"I'm talking about the kind of messy, dark mass..." Zhao Si gestured.

Bitter salt and salt crystals with more raw impurities are what Zhao Si wants.

"You can eat that salt, but you can't eat this salt. The general took it right." Jing nodded as a matter of course.

"It will be poisonous if you eat it!" Zhao Si said seriously.

"If you don't eat, you won't have salt." Jing replied.

"It's not that the salt stones are inedible. In the past, the family couldn't afford salt, so they would follow the rear of the animals to find salt stones in the mountains. They tasted salty even if they licked them, but they couldn't chew them," Jing recalled.

Salt is a rare thing in this era, so there is no salt that cannot be eaten.

If you can bite and swallow, you can eat it. As for the farts, there are only a few. Even if the heavy metals exceed the standard, you will not die if you eat them. In most cases, you will accumulate some chronic diseases due to the accumulation of heavy metals.

Unless it is seriously exceeded, it will die suddenly after eating.

If you really die suddenly, then you have a bad life, and the main thing is to rely on luck.

Zhao Si fell silent... According to the logic of Jing and Wang Li, there was nothing wrong with it.

"Then there must be no shortage of good salt in Qidi." Zhao Si teased.

Wang Li immediately smiled and said that Zhao Si was right.

"Qi Land has a lot of salt, and most of the salt mines are located in Qi Di, but the salt from Qi Di is only a little cheaper than well salt." Wang Li said.

"That's right, there are no more natural salt fields near the sea. You can boil the sea into salt, but you can't kill people after all. Besides, the cost of boiling the sea into salt is too high."

The current situation of salt in inland areas is generally like this. Those who eat dead people do not sell them, and those who do not eat dead people continue to sell them. If you pick up the stone eggs inside, maybe sell them to the group of nobles. Just sieve it through a sieve several times.

As for the salt of Qidi, it is better than sea salt. The heavy metals will not exceed the standard, and the sea salt is boiled. The cost is quite high, and the price has remained high.

Zhao Si didn't continue to entangle with them on this issue, people in this era are too optimistic.

If you can't die and get chronic diseases, blame yourself for your poor health.

I blame myself for my bad life after eating to death.

Ok……

Zhao Si already had some specific guesses about the salt circulating in the market in this era.

The most high-end and highest quality of these should be well salt.

Well salt is generally pure in texture, less impurities, and pure in taste.

The second is Qidi sea salt.

Then there are the salt mines in the interior.

There are many natural salt mines, and there are also many natural salt fields by the sea.

Then according to whether you can eat to death or not, the salt mines that you can eat to death are waste mines.

What can't be eaten to death is a good salt mine.

Maybe how long it takes to damage the body is also a measure, after all, the content of salt impurities in each place is definitely different.

After a long period of development, most of the edible and pure salt production areas are basically surrounded by forces from all over the world.The salt of this era also has a certain level.

Of course, there must be unscrupulous salt merchants who continue to sell unsalable salt with heavy metals exceeding the standard, mixing good salt and bad salt, as long as the price is cheap enough, as long as it can't be eaten, someone will always buy it.

Naturally produced salt rarely does not contain heavy metals, and many of these heavy metals cannot be filtered out by simple filtration methods such as sieves, so most salt mines have fatal effects on the body.

Even though the quality of salt sold in this era is already very poor, in fact it is still in short supply.

Most ordinary people can't afford salt, so they naturally have their own life tips.

Once the family's cattle and sheep are released on the mountain, the animals will find salt to lick themselves.

Even salt stones that cannot be chewed contain a certain amount of salt, and even many families still retain the habit of using boiled salt stones for seasoning.

"Look for those salt mines that are prone to illness and death..." Zhao Si said with a sigh.

According to what Wang Li and Jing said, I am afraid that many people are risking their lives to eat these salt mines that are prone to illness and death.

You can't even eat salt anymore. If you tell them that this stuff is poisonous, they won't listen.

After a while, Wang Li brought another pile of almost black salt lumps.

"That's it!" Wang Li said.

Zhao Si smelled it, and it didn't feel like salt, so she carefully licked it on the tip of her tongue.

The taste is so colorful, it has everything except salt.

Bitter, astringent, and muddy, with a hint of metal in it.

"Get some cloth."

Zhao Si asked Wang Li to get charcoal, and then found some weeds and reeds to light the campfire, and after burning through, it would be natural plant ash.

Plant ash, charcoal!

Natural adsorption filter purification artifact!

Crush the bittern salt, dissolve it in water, add plant ash and stir it, then wrap it in silk and filter it, and first filter out the insoluble impurities.

Repeat several times, basically there are not too many impurities that can be seen clearly by the naked eye, and charcoal is added to absorb pigments and other messy things.

Finally, wait for the water quality of the brine to become almost the same, then you can directly evaporate and precipitate the salt crystals.

I didn't have time to wait for the sun to dry out the salt, so I put it directly into the cauldron for cooking, and blue-gray salt crystals appeared.

"Green salt!" Looking at the final crystallization, Wang Li felt quite miraculous, and walked around the small cauldron for a long time.

This is clearly made from the dark brine.

From bittern salt that can eat dead people to high-quality blue salt?

Wang Li was a little confused.

The whole step was full of things he couldn't understand.

Didn't it become water?Add ashes and stir in it, and add charcoal.

How did it cook again in the end?

Zhao Si made a rough comparison and found that the salt production rate was a bit low.Only a third out.

In other words, in addition to the loss caused by filtration and purification, the impurities in this piece of brine salt are likely to exceed half!

This is not a salt crystal at all, but a messy mixed crystal of salt, other heavy metals, and even dirt and stones.

"Can I eat it?" Wang Li looked at the thin layer of the small cauldron in front of him and asked.

"Of course I can eat it!"

Without thinking, Jing fished some out of the cauldron and put it in his mouth.

Jing never questioned their captain.

Of course, the main reason was the lack of salt when going to sea, which is how Zhao Si boiled salt.

Jing vaguely remembered how shocked everyone was at that time.

"Of course I can eat it!" Zhao Si said with a smile.

Are there any other heavy metals in it?there must be.

With such a simple filtering method, how can it be possible to completely remove heavy metals?
It's just that for this era, after being double-filtered with plant ash and charcoal, it is basically impossible to eat, and basically there will be no particularly serious diseases.

Of course, it is not impossible to continue to purify, you can use the saturated crystallization method.

This is simple, and it is taught in junior high school chemistry.
