Portable Space Can be Summoned

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

What business?

That's right, it's the fine salt brought home by the younger generations of the Yang family.

Shun country is not near the sea, and most of the domestic salt comes from salt lakes in the northwest and well salt in central Sichuan.

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 to Cangshui County.

Although these sea salts are cheap, their quality is very poor. The table salt they buy has a bitter taste. Not only that, but it is also mixed with mud and stones.

Yang Yuan even guessed that if the rats didn't like to dig into the salt pile, they would be sold together with rat droppings.

Yang Yuan had eaten this kind of sea salt for a while since 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.

Yang Yuan was still young at that time, but after eating this salt, he wanted to use the materials at hand to purify them, at least without bitterness and sand.

Later, with the help of a group of relatives, the conditions at home quickly improved, and the salt we ate became loose salt that was a little more expensive than these bitter salts. Although there was still sand, it was eaten after being sieved by my mother. There is no problem with getting up.

After that, Yang Yuan gave up his plan to improve the quality of salt. After all, he was still very young and it was really troublesome to do something.

It is different now, when he made the decision to make money, he immediately thought of the idea of ​​purifying sea salt and reselling it.

It's just that at that time he had limited materials and insufficient funds, so he could only sell a batch of grain first to obtain development funds.

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

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

"Uncle Wei, you must be right to buy according to the order I gave you."

"Okay, since you want to buy, 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.

Therefore, if you want to buy bitter salt, you need to book in advance, and the price must be high enough.

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

Fortunately, Yu Shunguo's salt and iron monopoly, the price of salt has been around 30 to 40 yuan per catty.

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

Bitter salt is bitter because there are other soluble element ions mixed in the salt.

As long as these ions are separated, after dissolution and distillation, the bitter salt will become snow-white refined salt.

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

But this is Giethoorn Village, so he can only try his best to separate the most magnesium ions in the bitter salt. There are not many other calcium ions and sulfur ions, so the impact is not great.

So how to separate the magnesium ions in the salt?

It is easy to handle, adding an excessive amount of sodium hydroxide to the brine can cause the magnesium chloride and sodium hydroxide in the brine to react to produce colorless, non-toxic and tasteless magnesium hydroxide and sodium chloride, that is, salt.

Expressed in a formula is:

MgCl2+2NaOH=Mg(OH)2↓+2NaCl

How about it, keep it simple!

So as long as he got a large amount of sodium hydroxide, Yang Yuan could purify these bitter salts and turn them into another big source of income 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, with soda ash for steaming steamed buns.

If that's too much trouble, lime, plant ash, and salt can also produce sodium hydroxide.

In short, Yang Yuan used all the chemical knowledge he could remember, and finally developed a feasible and effective way to purify bitter salt that can be used on a large scale, and obtained a kind of snow-white table salt with crystal particles, known as snow Salt.

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

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 had already seen the scene of herds of cattle, sheep and furs being 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, knowing that he would not exaggerate the price.

Yang Yuan thought for a while, and finally gave a price that surprised Tie Mian, "It's always a catty, how about it?"

Although surprised by Yang Yuan's pricing, Tie Mian can also understand that this kind of salt is not for ordinary people to eat. When buying things from aristocratic families, they don't care whether you sell ten coins or ten guan. They only look at whether the goods are for themselves. needs.

Obviously this snow-white refined salt is the goods they need.

So a catty of Yiguan may be a little expensive in Shun country, but it is not a high price at all in Chu country or Qi country.

This kind of snow salt is hard to come by even in Qi State, which has developed by taking advantage of the fish salt, and it is very easy to sell it for three ounces per catty.

And the sales of iron noodles are in the grasslands where there is a serious shortage of refined salt, and the nobles there will definitely be willing to exchange a sheep for a catty of such snow salt.

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

"Ten stones."

In addition to some of the 20 stones of bitter salt that were wasted in the experiment and brought home by the brothers, there are still 15 stones left. The salt yield rate is very high.

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

In the following three months, 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 is necessary to let people go.

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 grassland.

"That's not an easy thing to do."

It was not an easy task for Tie Mian to transport these cattle and sheep alive to Giethoorn Village, 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 will not 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, did he really need these things?

Or have other ideas?

But business still needs to be done.

Yang Yuan has accumulated some summoners in the past three months. Counting the previous 38 people, Yang Yuan's Huoyunzhai has a total of 70 summoners, including 30 archers, 20 spearmen and 20 sword soldiers. .

Grain storage in warehouses has also returned to peak condition.

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