Chapter 460: Four Methods For Making Sea Salt, Producing Tens Of Millions Of Kilograms Of Salt In On
On the podium, Yan Changqing wrote four subtitles: "Lake Salt", "Well Salt", "Rock Salt", and "Sea Salt" under the word "Salt" at the top of the blackboard.
Then Yan Changqing looked back at Prince Zhu Biao, nodded, and replied while writing on the blackboard:
"There are indeed ways to make more salt."
"Before making salt, let's first understand the classification of salt.
"According to the different sources of salt, it can be divided into four types: lake salt, well salt, rock salt and sea salt."
"Lake salt is also called pool salt. For example, the salt lake in Yuncheng, Hedong, and the Chaerhan Salt Lake and Chaka Salt Lake in Xiningwei are rich in lake salt.
"Well salt, as the name suggests, is actually made by drilling down wells to obtain salt brine, and most of it comes from the Bashu region."
"Rock salt, also called rock salt or mineral salt, is generally salt formed after a certain lake or sea dries up. It is generally produced in Yunnan, Tibet and other places."
"Sea salt is made by scraping the salty soil from the seaside, and then using plant ash to absorb seawater, using it as a raw material for making salt.
Zhu Yuanzhang below, as well as the princes Zhu Biao, Zhu Di, Zhu Gang, Zhu Di and other princes, all nodded slightly when they heard this.
Except for rock salt, they have never heard of the four kinds of salt mentioned by Yan Changqing. They are all familiar with lake salt, well salt and sea salt.
Yan Changqing on the podium continued:
"Among these four salts, sea salt has the highest salt production!!!"
“Compared with sea salt, whether it is lake salt, well salt, or rock salt, firstly, they are only found in specific areas, and secondly, their quantities are relatively small.
"As for sea salt, theoretically, sea salt can be made anywhere there is sea water!!!"
“In other words, sea salt can be produced in any coastal area.
"Which is the coastal area that is larger, or the combined area of lake salt, well salt, and rock salt?!!"
"I think Your Majesty and Your Highnesses should also have an answer in their hearts."
Zhu Yuanzhang and the princes Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes below heard the words and couldn't help but nodded, saying that they knew the answer.
Between the area of the coastal area and the combined area of lake salt, well salt, and rock salt, the area of the coastal area must be the largest!!!
"So, if you want to make more salt, then the first choice must be to make sea salt!!!"
"Sea salt comes from seawater, and the general salt content of seawater is three to five percent!!!"
"In other words, one pound of seawater (500 grams) can produce about ten baht salt (15 grams) to eleven baht salt (25 grams).
“There are four ways to make sea salt. One is to boil seawater directly to make salt; the other is to make brine first and then fry it to make salt; the third is to make brine first and then sun-dry it to make salt; the fourth way is to directly sun-dry seawater to make salt.
"The method of directly boiling seawater to make salt can be traced back to the Shennong period. At that time, the Susha family was the first to boil seawater to make salt. He pioneered the history of Yanhuang salt production and was revered as the salt sect. "
"There is a word in "The Thousand Character Classic" called - Susha Boiling the Sea [referring to the allusion of Susha boiling the sea to make salt."
Yan Changqing once again wrote under the subtitle "Sea Salt": "Directly boil seawater to make salt", "First make brine and then fry to make salt", "First make brine and then sun-dry to make salt", "Directly sun-dry seawater to make salt" Four little subtitles.
Everyone, except Prince Zhu Biao, who is familiar with Confucian culture, knows that Susha Boiling the Sea in "The Thousand Character Classic" refers to the allusion of Susha cooking the sea to make salt.
Zhu Yuanzhang, as well as Zhu Xi, Zhu Fan, Zhu Di and other princes all looked like they had learned a lot and heard about it for the first time.
Because Zhu Yuanzhang's first enlightenment book can be said to be the Buddhist scriptures, and there is no historical allusion of Susha Boiling the Sea in the Buddhist scriptures.
Although later when he was teaching the princes Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes, he also read the "Thousand Character Classic" used in enlightenment [but he would not be serious enough to understand the records in the "Thousand Character Classic" of every allusion.
As for the princes Zhu Xi, Zhu Fan, Zhu Di, etc., compared to the prince Zhu Biao, they obviously do not like reading so much, or they do not like Confucian classics so much.
For "The Thousand-Character Essay", most of them just read and recite it hurriedly, and they are not very interested in understanding the various related allusions behind "The Thousand-Character Essay".
"First make brine and then fry it to make salt. This method of making salt is to scrape the salty soil from the seaside, and then use plant ash to absorb seawater as the raw material for making salt.
"When making salt, rinse the raw materials with water to form brine, then place it in an open container and burn it under a fire to evaporate the water. This method is called brine and decoction."
"Like those kitchen households in the Ming Dynasty, their method of making is this way!!!"
"However, the biggest problem with this method of making salt is that it requires a lot of labor and a lot of firewood, which can be said to be time-consuming and laborious!!!"
Yan Changqing wrote down the relevant salt-making methods under the subtitle "First make brine and then fry to make salt". At the same time, he also made a disparaging comment about the mainstream salt-making method in the Ming Dynasty today.
Below, Zhu Yuanzhang, who heard Yan Changqing belittle the Ming Dynasty's current method of making salt, and the princes Zhu Biao, Zhu Di, Zhu Fan, Zhu Di, etc., not only did not have displeasure on their faces, but looked at Yan Changqing expectantly.
After all, since Yan Changqing is disparaging the salt-making method of making brine first and then frying to make salt, it means that Yan Changqing has a more trouble-free and labor-saving method of making salt!!!
Compared with the more trouble-free and labor-saving method of making salt, Yan Changqing just said one or two disparaging words, which is not a big deal at all.
If necessary, they can even help Yan Changqing to belittle it.
"After the Song Dynasty, the sun-salt production method appeared, that is, [make brine first and then sun-dry it to make salt]."
"This method of making salt still scrapes the salty soil from the seaside, and then uses plant ash to absorb seawater as the raw material for making salt. Then when making salt, the raw materials are rinsed with water to form brine, and finally the water is dried in the sun."
"This method of making salt can save the firewood required for frying salt, which greatly reduces the cost of making salt. Therefore, it can be said to be much more advanced than the method of making salt by frying it!!!"
Yan Changqing, who wrote down the relevant salt-making methods under the small heading "First make brine and then dry to make salt" on the blackboard, said in a calm tone.
The sun-dried salt production method had already appeared in the Yuan Dynasty. From the second year of Emperor Taizong of the Yuan Dynasty to the twenty-third year of Emperor Shizu of the Yuan Dynasty (1320-1378), three salt fields, namely Haifeng, Hairun and Haiying, were built along the Gaojin River in the north of Jieshi Mountain.
The method of making salt in these three salt farms is to fry and dry it in parallel.
However, although the sun-salt production method had already appeared at this time, during the Hongwu period of the Ming Dynasty, the sun-salt production method had not spread, spread and been applied on a large scale. Even people who had heard of the sun-salt production method had no idea. Not many people.
It was not until the Yongle period of the Ming Dynasty that more people knew about the sun-salting method. The Ming Dynasty began to abolish some pots and stoves and began to rebuild salt fields to use the sun-salting method to make salt.
Later, in the first year of Jiajing reign of Emperor Shizong of the Ming Dynasty (1522), Haifeng Salt Farm took the lead in frying salt instead of drying it. At this point, the frying salt method gradually withdrew from the stage of history, and the salt drying method became unpopular.
Therefore, for the Ming Dynasty, which was in the 14th year of Hongwu, the salt-drying method can still be regarded as an advanced and unique salt-making method!!!
·------****-------.
At least Zhu Yuanzhang, who had heard about the method of making sun-salted salt for the first time, as well as the princes Zhu Biao, Zhu Di, Zhu Fan, Zhu Di, etc., all had excited expressions on their faces.
Compared with the salt-making method of "making brine first and then drying it to make salt", "making brine first and then drying it to make salt" can be said to save most of the manpower, material and financial resources!!!
Even if Yan Changqing did not come up with a more advanced method of making salt later, just using the "sun salt method" instead of the "fried salt method" would be enough to increase Mu Ming's current salt production by at least five times!
In other words, the Ming Dynasty's fiscal revenue from salt could at least increase three to five times, and it would continue to increase!!
From this point alone, it is not an exaggeration to say that Ming Dynasty can continuously and cumulatively create hundreds of millions, or even billions or billions of profits!!!
After all, salt is an indispensable, hugely consumed, and rigidly demanded item in the daily life of the people of the Ming Dynasty.
Since ancient times, I have never heard of any court where the people can truly have no shortage of salt.
Thinking of this, Zhu Yuanzhang, as well as the princes Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes, looked at Yan Changqing even more expectantly.
After all, [making brine first and then drying it to make salt] can already increase the current salt production of Ming Dynasty by at least three to five times.
According to the rule that Yan Changqing just mentioned, the more advanced the salt production method is, the more salt will be produced.
So, wouldn’t the salt production method of [directly drying seawater to make salt], which ranks behind the [preparing brine first and then drying to make salt], increase the salt production of the Ming Dynasty by at least ten times?!!
If it can really increase the current salt production of the Ming Dynasty by more than ten times, then maybe the Ming Dynasty will become the tenth dynasty in history where the people are no longer short of salt!
!
Yan Changqing glanced at the podium. Zhu Yuanzhang, who looked excited, as well as the princes Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes, did not mean to whet their appetites, and directly explained the last method of making salt. come out:
"To directly dry seawater to make salt, this method of making salt is to build a multi-layered salt pond on the beach, from top to bottom, introduce seawater from the top layer, and dry it layer by layer.
"When the seawater flows into the last layer, the brine has reached a very high concentration."
"Finally, if the weather is fine, the last layer of brine will turn into salt after being exposed to the sun for one day!!!"
“This method of making salt can be said to be the most advanced version of the sun salt method. It is a step further than the method of making brine first and then sun-drying to make salt. Even the step of making bacterial water is omitted.
"Theoretically, as long as there are enough multi-layer salt ponds built in coastal areas, the more sea salt will be produced in the end!!!"
"Even if you can turn into tens of thousands of catties of salt in one day, it's not an absurd thing!!!"
Yan Changqing, who wrote down the relevant salt production methods under the small heading "Directly Sunning Seawater into Salt" on the blackboard, said calmly.
Before entering the industrial society, the salt production method [directly drying seawater to produce salt] can be said to be the method that produced the most salt in ancient agricultural society.
Even as Yan Changqing said, it is possible to gain weight every day.
After all, judging from the current situation, the coastal area of the Ming Dynasty was still very vast.
And as long as there are enough multi-layered salt ponds dug in coastal areas, the more salt will naturally be produced in the end.
It is not an extravagant expectation to produce tens of millions of pounds of salt in just one day.
