After saltpeter is dissolved in water, it will absorb a lot of heat and even freeze.
However, this kind of ice cube is not edible, so you need to choose a small container with good thermal conductivity and fill it with clear water.
As the heat in the large container continues to dissipate, the clean water in the small container also cools down and freezes.
The principle seems simple and beautiful.
But to condense water into ice on a hot summer day, a large amount of saltpeter is needed.
What's more, in order for the water in the small container to freeze, there are higher requirements for the size and temperature of the large container.
so……
"It's freezing, it's really freezing!"
The fourth prince shouted happily, danced and was as happy as a child.
Everyone around looked shocked.
Did the Second Master (the Imperial Envoy) really make ice out of thin air?
Amazing.
Jia Lian looked as usual and walked to the big wooden barrel.
After consuming three full bags of saltpeter, ice particles could finally be seen in the water in the barrel.
But when I opened the lid of the iron bucket, the water inside was still extremely clear.
"not enough."
Jia Lian continued to ask people to add saltpeter. When the saturation was visible to the naked eye, he asked people to bring the huge lid of the big wooden barrel and close it.
This can reduce the loss of air conditioning.
The whole place was quiet, as if everyone was waiting for the unveiling of a sacred event.
After a cup of tea, Jia Lian asked someone to open the wooden lid.
The fourth prince was the first to rush forward.
"Really, really ice!"
Inside the barrel, within a short period of time, the ice ballast had solidified into ice cubes, and a biting cold air was blowing out.
There was no need for Jia Lian to do anything anymore. The fourth prince stretched out his hand and opened the lid of the tietong embedded in the middle of the ice cubes.
"It's freezing too!"
The fourth prince looked back at Jia Lian happily.
Jia Lian also walked over and had a look.
Sure enough, he had carefully designed the tool, and the effect was much better than expected.
Although you can see at a glance that the ice in Tietong is very light in color, it seems that if it is stirred, it will all break into ice particles and frost.
After all, it was frozen.
Unfortunately, Jia Lian glanced aside and saw that almost half of the saltpeter he had sent troops to collect in the past few days had been consumed.
After spending so much manpower, material and financial resources, we only got this one bucket of crushed ice, which shows the low efficiency.
It is estimated that except for the rich and powerful, no one in the world has the ability to make ice in this way in summer.
If the really wealthy people want to use ice, they can naturally dig ice cellars. In winter, they can choose ice cubes with high quality and transport and store them.
Prince Wala walked up to Jia Lian with a smile and said loudly: "The general's magical skills really amaze me.
The weather is so hot now, and I and my entourage are also suffering from the scorching heat. So I would like to ask you, the general, to share some of the ice cubes in the bucket with me?
"One Sword Dominates"
Don't worry, general, I'm not asking for it in vain, I can exchange it with silver."
Prince Wala's attitude was very sincere, and Jia Lian had no intention of offending him, so he wanted to agree.
"no."
The fourth prince turned back and said with a serious face: "Jia Lian, you agreed that these ice cubes are all for me."
Jia Lian glanced at Prince Wala in embarrassment and said, "I'm sorry, Third Prince. These ices were indeed prepared by me for the Fourth Prince and His Royal Highness, and I have no right to deal with them."
But the prince must have seen all the ice-making methods just now.
If the prince wants to use ice, he can use the remaining saltpeter here at will. And according to this method, it will be very easy to get ice cubes."
Prince Wala glanced at the fourth prince, an imperceptible coldness flashing in his eyes.
Looking back, he still had a humble attitude: "In that case, thank you so much, General."
"You're welcome, Prince."
"By the way, I'm very grateful to you for taking the time to trouble the general to escort me and the princess back to Wala to get married. I'm worried that I can't repay you in return.
It just so happens that my father Khan admires strange people like generals the most. When I return to the royal court, I will definitely recommend generals to my father Khan.
With his talents as a general, he will surely be put to great use by my father Khan."
Prince Wala's sudden words not only stunned Jia Lian, but also made other people around him prick their ears.
The fourth prince originally thought that he was being stingy by not giving Prince Wala ice cubes. In fact, the prince had not offended him.
But when he heard Prince Wala's words, he suddenly became furious.
"Hey, are you awake? In front of my prince, you want to instigate my father's confidants?
Moreover, why do you think that he left me, a dignified general in my country, to go to your Oara and serve you?"
Although the fourth prince usually does not care about political affairs, it does not mean that he will forget his identity as a member of the Wei royal family.
This bullshit prince actually wanted to poach his father in front of him!
Prince Wala smiled and said: "The fourth prince made a strong statement.
Now the Wei Dynasty and I, Wala Yong, have formed an alliance and are as close as one family. Since we are one family, how can we instigate rebellion?
As long as our Wala can give General Jia a greater official position and a higher status, then what's wrong with General Jia staying in our Wala for a greater future?
Could it be that the fourth prince does not agree with the alliance between Wei and Oara in his heart, and still regards us Oara as a foreign enemy?"
"you……!"
The fourth prince immediately felt that he had fallen into the opponent's trap.
Even if he doesn't like the idea of forming an alliance with his relatives, he still knows that opposing it here at this time will not only have no effect, but will only make the officers and soldiers wait and laugh at him for not knowing the general situation.
So he ignored Prince Wala and looked at Jia Lian angrily.
He didn't believe that Jia Lian, who was a prince for generations in the Wei Dynasty, would give up his roots in the Wei Dynasty and become an official in some foreign tribe.
Faced with the direct gaze of the fourth prince, Jia Lian said: "Thank you very much for Your Highness the Prince's love. However, I have received the Emperor's favor and never dare to forget to serve the King for a moment. I am afraid that I will live up to His Highness the Prince's kindness."
Of course, Jia Lian couldn't be so stupid as to be tempted by Prince Wala's casual promise.
Not to mention that Prince Wala's words contained some gold. Even if he was sincere, Jia Lian would not consider it.
On the other hand, other people who had an unsatisfactory life in the Wei Dynasty might still have a chance. Unfortunately, if Wala digs out people like that, they probably won't be of much use.
Moreover, Jia Lian could clearly see that Prince Wala was deliberately teasing the fourth prince.
This couldn't help but make Jia Lian feel secretly vigilant.
Prince Wala spoke slowly, and he kept smiling when facing them.
But the fourth prince had just offended him, and he couldn't help but fight back. This shows that he is not a simple and honest person!
Hearing Jia Lian's direct statement, the fourth prince looked at Prince Wala proudly, snorted, and called for people to take away Tietong and the ice cubes.
He wanted to take such freshly made clean ice cubes to the royal sister to enjoy!
Princess Zhaoyang's boudoir, after the fourth prince excitedly brought in the fruit plate and cold drinks, Princess Zhaoyang took a look at it, then faced the proud look of the fourth prince and asked with a smile: "This is what Jia Lian used in a magical way to make
Made of ice cubes?”
"Uh, Sister Huang, do you know everything?"
Princess Zhaoyang smiled and said nothing.
The fourth prince didn't care at all, and said with a smile: "Sister, you don't know, Jia Lian found a lot of magical stones from nowhere. Well, these ice cubes were made by him from those stones.
Sister Huang, feel free to enjoy it, there is still a lot of ice, it’s full of Yitietong, I’ve asked people to store it in the ice collection, and I’ll have it sent to Sister Huang later.”
"Is the stone you are talking about called saltpeter?"
"Hey, it seems that I did hear Jia Lian say it was saltpeter. Could it be that, Sister Huang, you also know this method?"
Princess Zhaoyang shook her head.
Jia Lian and the fourth prince made ice with great fanfare, and it was not kept secret, and it had already been spread.
Princess Zhaoyang was the first to receive the news.
Then she learned about a method of "making ice with saltpeter" from the old nun who was accompanying her. This was what she thought.
According to the old grandmother, when she was in the palace, there was not enough ice in the ice cellar in the palace every summer.
Some unpopular concubines got this idea from nowhere and made ice in the palace, causing a lot of noise.
Later, it was banned by the Empress Dowager because in order to obtain enough saltpeter, the concubines frequently sent eunuchs out of the palace to collect and purchase it, which had a very bad influence.
Since there is such a method, Jia Lian knows that Princess Zhaoyang does not find it too strange.
However, according to the old lady, this method of making ice is extremely inefficient and time-consuming. How could Jia Lian do this while marching?
Could it be that, like his brother, he was also worried that she would be injured by the heat, so he deliberately wanted to please her...
Unable to confirm this guess, when the fourth prince left, Princess Zhaoyang ordered her attendants to make all the ice cubes sent by the fourth prince into fresh cold drinks and fruit plates to reward the accompanying officials.
