Portable Space Can be Summoned

In the past few months, Yang Yuan has rarely been in the grain business. Although this business is getting better and better, there is also a lot of grain produced in Yang Yuan's space, so he switched to other businesses.

What business?

That's right, it's the refined salt that the younger generation of the Yang family took home.

Shun State is not near the sea, and most of the salt in the country comes from the salt lake in the northwest and the well salt in the middle of Shu.

However, Cangshui County is close to Qi State and is closer to the sea, so a large amount of sea salt from Qi State is sold into Cangshui County.

Although these sea salts are cheap, they are of poor quality. The salt that I bought has a bitter taste. Not only that, but it is also mixed with soil and stones.

Yang Yuan even guessed that if the mice didn't like to dive into the salt piles, they would have been sold with mouse droppings.

Yang Yuan ate this kind of sea salt for a while when he was a child. At that time, his father had just died in an accident, the pillar of the family disappeared, and life began to be tight.

At that time, Yang Yuan was still young, but after eating this kind of salt, he wanted to use the materials at hand to purify it, at least not to have bitterness and sand.

Later, with the help of a group of relatives, the conditions of the family quickly improved, and the salt that was eaten became loose salt that is a little more expensive than these bitter salts. Although there is still sand, it is eaten after being sieved by the mother. It's okay to get up.

After that, Yang Yuan also gave up the plan to improve the quality of salt. After all, it was really troublesome for him to do something when he was very young.

It's different now. The first time he made the decision to make money, he thought of the idea of ​​purifying sea salt and then reselling it.

However, at that time, he had limited materials and insufficient funds, so he could only sell a batch of grain to obtain development funds.

Later, after the first transaction was successful, Yang Yuan purchased enough bitter salt, soda ash for purification, slaked lime and other materials through Uncle Wei.

Uncle Wei once thought that he was going to build a house for steamed buns.

"Uncle Wei, it's definitely right for you to buy according to the order I gave you."

"Okay, since you want to buy it, I'll place an order with them."

Don't think that no one buys bitter salt because it is bitter, astringent, and sandy. In this era, many people don't even eat salt, and only use something called vinegar cloth as seasoning.

So if you want to buy bitter salt, you need to book in advance, and the price is high enough.

However, this is not a problem for Yang Yuan who still has fifty taels of gold.

Fortunately, in Shunguo’s salt and iron monopoly, the price per catty of salt has always been around thirty or forty cents.

The price of one stone salt was only three or four, so Yang Yuan ordered twenty stones in one go, and he did the test first.

The reason why bitter salt is bitter is that there are ions of other elements that can dissolve in the salt.

As long as these ions are separated, after being dissolved and distilled, the bitter salt will become a pure white salt.

If there are enough chemical solvents around, Yang Yuan can easily decompose all other ions in the salt.

But this is Giethoorn Village. He can only try his best to separate the most magnesium ions in bitter salt. Other calcium ions and sulfur ions are not much and have little effect.

So how do you separate the magnesium ions from the salt?

It is easy to handle. Adding excess sodium hydroxide to the brine can make the magnesium chloride and sodium hydroxide in the brine react to form colorless, non-toxic and tasteless magnesium hydroxide and sodium chloride, that is, salt.

The formula is expressed as:

MgCl2+2NaOH=Mg(OH)2↓+2NaCl

How about it, simple!

So as long as he gets a lot of sodium hydroxide, Yang Yuan can purify these bitter salts and turn it into another big source of money for him.

So how to get sodium hydroxide.

It is also very simple. A large amount of sodium hydroxide can be obtained by reacting calcium hydroxide, that is, slaked lime for construction and soda ash for steaming steamed buns.

If you think it's too troublesome, you can also use lime, plant ash and salt to produce sodium hydroxide.

In short, using all the chemical knowledge he could remember, Yang Yuan finally developed a feasible and effective method for purifying bitter salt that can be used on a large scale. Salt.

When Tie Mian traded this salt with Yang Yuan for the first time, he almost dropped his jaw.

When did Giethoorn Village have access to such snow-white refined salt?

This is something only those noble families can afford.

If you sell them to the grasslands...

Tie Mian has seen the scene when herds of cattle, sheep and furs are packed into his cottage.

"I want as much salt as you have."

"What about the price?"

"you decide."

Tie Mian said cheerfully, after several transactions, he also had some understanding of Yang Yuan, and knew that he would not ask for a price.

Yang Yuan pondered for a moment, and finally gave a price that surprised Tie Mian, "How about a pound of consistently?"

Although he is surprised by Yang Yuan's price, Tie Mian can understand that such salt is not for the common people. When a family buys something, they don't care if you sell it for ten cents or ten dollars. They only look at whether the goods are their own. needs.

Obviously, this snow-white refined salt is what they need.

Therefore, a pound may be a bit expensive in Shun, but in Chu or Qi, it is not a high price at all.

Such snow salt is hard to come by even in the Qi Kingdom, which has developed by taking advantage of the benefits of fish salt, and it is very easy to sell it for a price of three ounces per pound.

The sales of iron noodles are even more in the grasslands where there is a serious shortage of refined salt~www.wuxiahere.com~ The nobles there are definitely willing to exchange a sheep for a pound of such snow salt.

"Okay, how much of this snow salt do you have now?"

"Ten stones."

In addition to the 20 stones of bitter salt that was wasted in the experiment and given to the brothers to take home, there are still 15 stones left, and the salt yield can be said to be very high.

But Yang Yuan still didn't use it all for the trade, he left five stones of snow salt, and good things are never afraid of not being sold!

In the three months that followed, the transactions between Yang Yuan and Tie Mian became bigger and bigger. It was not only Yang Yuan who sold things to Tie Mian, but now Yang Yuan also purchased some goods through Tie Mian.

Of course, it can't be related to salt, and it's a must.

Yang Yuan proposed to buy cattle, sheep and wool from Tie Mian after he knew that Tie Mian could freely travel to and from the grasslands.

"That's not an easy thing."

It was not easy for Tie Mian to transport these cattle and sheep to Giethoorn Village alive, otherwise the intestines of the sheep would not be occupied by the Eighteen Bandits.

"Do your best. If there are no live ones, I want beef and mutton, as well as bones and wool, but the price won't be that high."

Yang Yuan said helplessly.

Tie Mian took a deep look at Yang Yuan. He always felt that the purpose of this little friend was not so pure. Does he really need these things?

Or have other ideas?

However, business still has to be done.

Yang Yuan has accumulated some summoned soldiers in the past three months. Counting the previous 38 soldiers, Yang Yuan's Huoyun Village has a total of 70 summoned soldiers, including 30 archers, 20 spearmen and 20 swordsmen. .

Grain storage in warehouses has also returned to peak condition.

There is only one sentence, Yang Yuan is a little stronger now.
