Wang Li moved very quickly and got the inedible salt in a short time.
Zhao Si fell into silence when he saw the stone in Wang Li's hand.
"I asked you to bring salt." Zhao Si said.
"Yes, isn't it inedible salt?" Wang Li looked confused.
What he brought was inedible salt. The stones and salt crystals were mixed together, or they were simply salt stones licked by animals in the mountains.
"Is there any problem?" Wang Li asked.
"It is inedible salt, but is it possible that it is stone and not salt?" Zhao Si asked.
"Brother, this is salt!" Jing whispered from the side.
Zhao Si was stunned for a moment, and his face was full of doubts: "Can this be called salt?"
This is clearly a stone!
"I'm talking about that messy, dark mass..." Zhao Si gestured.
Brine salt and salt crystals with more original impurities are what Zhao Si wants.
"That salt is edible, but this salt is inedible. The general got it right." Jing nodded matter-of-factly.
"You will be poisoned if you eat it!" Zhao Si said seriously.
"If you don't eat, you won't have salt." Jing replied.
"This salt stone is not inedible. In the past, my family couldn't afford salt, so they would follow the animals to the mountains to find salt stones. They tasted salty when they were licked, but they couldn't bite them," Jing recalled.
Salt is a rare thing in this era. There is no salt that cannot be eaten.
If you can bite it and swallow it, you can eat it. As for those who burp and fart, those are the minority. To be honest, even if the heavy metal exceeds the standard, you will not die after eating it. In most cases, some chronic diseases will accumulate due to the accumulation of heavy metal.
Unless it is seriously exceeded, you will die suddenly after eating it.
If you really die suddenly, then you have bad luck. The main thing is to rely on luck.
Zhao Si fell into silence... According to Jing and Wang Li's logic, there was really nothing wrong with them.
"Then Qidi is certainly not short of good salt." Zhao Si teased.
Wang Li immediately smiled and said that Zhao Si was right.
"There is a lot of salt produced in Qidi. Most of the salt mines are in Qidi, but the salt in Qidi is only slightly cheaper than well salt." Wang Li said.
"That's right, there are not many natural salt fields near the sea. You can boil the sea into salt, but you can't kill people. Besides, the cost of boiling the sea into salt is too high."
The current situation of salt in the inland areas is generally like this. Those who can eat it to death will not be sold, and those who can't eat it will continue to sell it. I will pick up the stones and eggs in it, and maybe sell it to those noble people. Just sift it through a sieve a few times.
As for the salt from Qi Di, it is better than sea salt, because the heavy metals will not exceed the standard, and it is made by boiling the sea to make salt, which is quite expensive and the price has always been high.
Zhao Si did not continue to struggle with this issue with them. People in this era are too optimistic.
If you can't eat enough to die, you can blame yourself for your poor health if you get a chronic disease.
If you eat to death, blame yourself for your bad luck.
Um……
Zhao Si has already made some specific guesses about the salt circulating on the market in this era.
Among them, the most high-end and the best quality should be well salt.
Well salt generally has a pure texture, fewer impurities, and a pure taste.
Next is Qidi Sea Salt.
The next one is the salt mines in the inland areas.
There are many natural salt mines, and there are also many natural salt fields on the seaside.
Then they are divided according to whether they can eat to death or not. The salt mines that can eat to death are waste mines.
If you can't eat it to death, it's a good salt mine.
Maybe how long it takes to eat bad food 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 salt production areas with pure texture have been basically surrounded by various local forces. The salt of this era also had certain grades.
Of course, there must be some unscrupulous salt dealers who continue to sell unsellable salt with excessive heavy metals. Good salt and bad salt are mixed together. As long as you can eat it to death and the price is cheap enough, there will always be people who buy it.
Naturally produced salts rarely contain heavy metals, and many of these heavy metals cannot be filtered out through simple filtration methods such as sieves. Therefore, most salt mines have a fatal impact on the body.
Even though the quality of the salt sold in this era is already very poor, it is actually still in short supply.
Most ordinary people cannot afford salt, so they naturally have their own tips for life.
When the family's cattle and sheep are released into the mountains, the animals will find salt to lick themselves.
Even salt stones that cannot be chewed contain a certain amount of salt, and many families even still retain the habit of boiling salt stones for seasoning.
"Look for those salt mines that are easy to get sick and die from..." Zhao Si sighed and said.
According to what Wang Li and Jing said, there are probably many people who are risking their lives by eating these salt mines, which are prone to illness and death.
You can't even eat salt. If you tell them that this thing is poisonous, they can't listen.
After a while, Wang Li brought another pile of salt blocks that were almost black in texture.
"That's it!" Wang Li said.
Zhao Si smelled it and found that it didn't feel like salt. He carefully sipped a little on the tip of his tongue.
The taste is colorful, with everything except salt.
Bitter, astringent, and muddy, with a bit of a metallic taste in it.
"Get some cloth."
Zhao Si asked Wang Li to get charcoal, and then found some random weeds and reeds to light the bonfire. After burning through, it would become natural plant ash.
Plant ash, charcoal!
Natural adsorption filtration and purification artifact!
Crush the brine salt, mix it into water, add plant ash and stir, then wrap it in silk and filter it to filter out the water-insoluble impurities.
Repeat this several times, and there will basically not be too many impurities that can be seen clearly with the naked eye. Add charcoal to absorb pigments and other messy things.
Finally, when the quality of the brine becomes almost the same, you can directly evaporate and precipitate the salt crystals.
There was no time to wait for the sun to dry out the salt, so he put it directly into the cauldron and cooked it, and blue-grey salt crystals appeared.
"Green salt!" Wang Li looked at the final crystal and felt it was magical. He walked around the small cauldron for a long time.
This is obviously made from the dark brine salt.
From brine salt that can kill people to high-quality green salt?
Wang Li was a little confused.
The whole process was full of things he couldn't understand.
Didn't it turn into water? Also add ash and stir it in, and add charcoal.
Why was it cooked again in the end?
Zhao Si roughly compared it and found that the salt production rate was a bit low. Only a third came out.
In other words, in addition to the losses caused by filtration and purification, the impurities in this piece of brine salt are likely to exceed one-half!
This is not salt crystals at all, but a mess of mixed crystals of salt, other heavy metals, and even soil and stones.
"Can it be eaten?" Wang Li looked at the thin layer in the small cauldron in front of him and asked.
“Of course you can eat it!”
Jing took some out of the cauldron and put it into his mouth without thinking.
Jing never questioned their captain.
Of course, the main reason was the lack of salt when going to sea. This is how Zhao Si boiled the salt.
Jing vaguely remembered how shocked everyone was at that time.
"Of course you can eat it!" Zhao Si said with a smile.
Are there any other heavy metals in it? there must be.
How can it be possible to completely remove heavy metals with such a crude filtering method?
But for this era, after undergoing the double filtration of plant ash and charcoal, it is basically impossible to kill people, and there are basically no particularly serious diseases.
Of course, if you still want to continue purifying, you can use the saturated crystallization method.
This is simple and is taught in junior high school chemistry.
