Chapter 760
"Lao Jiu, are you kidding?" Tang Long said in disbelief.
Tang Shuheng suddenly changed his expression: "Ninth brother, you should know that salt has been controlled by the government since thousands of years ago, and salt has naturally become one of the main financial revenues of all countries in the world. However, after thousands of years of development, most of the salt on the market is still crude. There are only a handful of salts and refined salts, and even the major royal families can only barely suffice for themselves!"
"As we all know, the raw material of salt is toxic and requires various complex methods such as refining. After removing the toxic substances in the raw salt, it can be barely refined into coarse salt. It is extremely difficult to transform coarse salt into refined salt. There are many coarse salts on the market. Salt is quite expensive, let alone refined salt!”
"I bet that of all the officials in the DPRK and China, not many of them have eaten refined salt. Most of the time it's not that they can't afford it, but that it's expensive but not marketable!"
"Not bad!" All civil and military officials nodded one after another, and they all agreed with Tang Shuheng's statement.
After all, most officials are supported by wealthy families. They do not lack salt in their lives, but they lack refined salt. Every year, almost all the refined salt produced in the Tang Dynasty flows into the royal family. The wealthy families below can get very little refined salt. They almost eat it. Both are fine coarse salts, but there is still a certain gap compared with refined salts.
Tang Yu knew that the world in front of him was equivalent to the Warring States Period of China. The seven countries in the world were indeed more than a little behind the modern times in terms of salt refining.
Moreover, Tang Shuheng was right. For thousands of years, table salt has been controlled by the government, so the serious table salt on the market is also known as official salt.
Salt raw materials contain various salts such as sodium oxide, potassium oxide, and magnesium oxide.
Among them, table salt is sodium oxide, excluding other salts, especially magnesium oxide, which tastes bitter and salty and is toxic to the human body. Regular official salt will remove these toxic substances.
Remember https://m in one second.
Since ancient times, salt has been a necessity of life. If people do not eat salt for a long time, they will become weak and sick, without strength and energy.
But it is not easy to extract official salt without toxins. The ancients mainly used the most primitive boiling salt and decoction salt to extract table salt. These two methods are simple and quick, but it is difficult to extract refined salt.
In order to increase tax revenue, the official price of salt is often very high. Many people cannot afford official salt, so private salt sales are derived. Private salt sales are huge profits and seriously affect the country's governance. In ancient times, if you dare to sell salt, you will be punished. If not, he might be beheaded.
Compared with official salt, the price of private salt is not cheap. In ancient times, in order to solve the problem of eating salt, many people dug for salt from the soil.
The so-called earth salt is the raw material of table salt without any processing or refining. Many people will be poisoned after eating this kind of earth salt. Many people die from eating earth salt.
Having just learned that Da Chu had imposed economic sanctions on Datang, Tang Yu had a headache at the time. After some analysis, he was shocked to find that he could use modern salt refining technology to refine refined salt.
In modern times, what everyone eats is refined salt. It seems commonplace, and the quality of salt in a bag is not bad. But in ancient times, it was just a treasure. To a certain extent, refined salt was even more valuable than gold.
As a modern man, Tang Yu knew very well how to purify table salt. As long as he could refine salt on a large scale, he would definitely be able to cause a sensation in the Seven Kingdoms.
Emperor Tang looked at Tang Yu and said with emotion: "Yu'er, it's not easy to refine salt. I don't know how many people have tried it over the past thousands of years, but unfortunately none of them have failed!"
"That's because their method is wrong!" Tang Yu chuckled.
"Wrong method?"
After hearing this, Tang Huang said with great interest: "Does it mean that Yu'er, you already have a method for refining refined salt here?"
"There is no method yet, but I have an idea. Once my idea is feasible, the refined salt will be more delicate and rich in taste. If the father wants to try it, please explain in advance that the child will need a lot of research and development funds!" Tang Yu smiled evilly.
Naturally, he would not say in front of everyone that he can refine salt. If he wants to hand over the method of refining salt, he must have enough benefits.
At present, Tang Yu's expenses are huge. He has to find a reason to ask his cheap dad for more money, otherwise the 500 million taels of silver from Da Chu may be used up in other ways.
Emperor Tang could tell that Tang Yu wanted to take advantage of the situation, but breaking through Dachu's economic sanctions was imminent, and he didn't want to waste a moment.
In desperation, Emperor Tang could only follow Tang Yu and ask, "I wonder how much R&D funding you plan to ask for, Yu'er?"
