Saltpeter dissolves in water and absorbs a lot of heat, which is how saltpeter makes ice. Thanks to his previous experience of reading novels, Liszt knows a lot of similar common sense.
And he also knows that saltpeter can be used repeatedly.
"Saltpeter is a magical substance that can be dissolved in water, and then make the water very cold until it freezes." Liszt directed the servant to pour the white powder into the basin.
Then you can see the powder gradually melting.
Tom put his finger into the water and shouted in surprise: "Master, sir, the water, the water is really cold, it's so cold!"
Galtai squeezed Tom away, curious and hesitant, and finally put his fingers in: "It is indeed much colder than before, Liszt, is this a magician's method? I once saw a magician who was good at ice magic." , he always makes a lot of ice in the summer to make money."
However, after waiting for a while, the water was only cooler, not frozen.
"Liszt, why didn't it turn into ice?"
"Mr. Gao Ertai, saltpeter is not enough to make ice like this. Now it is just to prove that they are indeed saltpeter." Liszt smiled lightly, "Then, while crushing stones, collect all these saltpeters and send them to In the castle, don't miss anything."
"Okay, I look forward to the moment when you make ice cubes. There is ice in summer, and this is the enjoyment that nobles should have."
Tomorrow is the Sea Festival, and the castle will hold a banquet.
night.
Looking at the saltpeter powder collected in a day, which was as large as a wooden barrel, Liszt excitedly directed the servants to start making ice with real saltpeter.
Saltpeter dissolves in water, absorbs heat, and turns water into ice.
But the ice water that directly melts saltpeter is poisonous, so you need to prepare a tank and a copper basin with better thermal conductivity. Put water in the vat, put water in the copper basin, and put the copper basin in the vat again. Pour the saltpeter into the tank water and wait for it to dissolve and absorb heat, turning the water into ice.
Because there is enough saltpeter powder prepared, the effect of dissolving and absorbing heat is super strong.
Within a quarter of an hour, the water in the jar began to slowly condense, and after a while, even the water in the copper basin began to freeze.
"It's freezing!"
"It's really freezing!"
"A magical scene, this is the method of the legendary alchemist!"
Marcus, Gaultier, Isaiah, and Blair, who were on the sidelines, were all amazed. In their impression, only in winter can there be ice, and the nobles built ice cellars to enjoy the refreshment brought by ice in summer. But an ice cellar is a luxury, and only a rich lord can organize a huge ice mining team in winter to dig ice from rivers and lakes.
A down-and-out aristocrat like Gao Ertai can only taste a few pieces of ice in Tulip Castle every year.
Marcus, Blair, and Isaiah are not even eligible to taste Xia Bing.
Liszt was equally excited. He had heard of making ice with saltpeter, but it was the first time to make it himself. Seeing water turn into ice with your own eyes is a shocking experience.
"My lord, it's frozen." Thomas surrounded the tank, his eyes shining.
"Get the ice." Liszt nodded, maintaining a reserved aristocratic smile on his face, calm and dignified, "Cut the ice cubes into small pieces, and gentlemen and ladies can each get a small piece tonight." ice."
Carter whispered: "Master, the ice is too expensive, so the servants don't need it?"
"It's all right, Mr. Carter, just do as I say."
"Yes, my lord, for your generosity, on behalf of all the servants, I would like to express my sincerest respect to you." Carter bowed and saluted. It was indeed the luck of the servants to meet a generous noble lord.
After speaking, he directed Thomas to carry the ice cubes in the copper basin and enter the kitchen to start cutting.
Liszt called Tom again: "Keep this jar of ice water well, and take it out to dry after the sun comes out tomorrow, don't waste a single drop."
Gao Ertai was puzzled: "Liszt, what's the reason for this? It's good to use these ices, why should they be sunburned?"
"The saltpeter directly melts the condensed ice. Of course it can be used, but it can't be eaten. If they are dried in the sun, they will become saltpeter again, and then used repeatedly to make ice."
"Is saltpeter so magical?"
"It's far more miraculous than you can imagine." Liszt thought in his heart—if he found brimstone, he would dare to configure black powder now.
Perhaps compared with yellow powder, black powder is not strictly considered explosives, but it is still a flammable and explosive high explosive. It is suitable for making some earth bombs, at least not weaker than the magic released by low-level monsters. Used in low-level battles, it still has a surprising effect.
Of course, in a world of dragons, elves, and magic, black powder has no decisive advantage.
The dishes at the dinner party were not rich, and Liszt was reluctant to entertain Galtai and the others every day with big fish and meat. The materials of the castle were his personal guarantee for a luxurious life.
The drinks are also pretty bad, mostly sour non-hopped beers.
But the atmosphere at the banquet was high, because everyone had a few crushed ice cubes in their cups. The ice cubes melted, making the whole glass of beer cold. Drinking it in one gulp, the whole person's heart was instantly cooled and brightened. In this hotter and hotter weather, it is definitely the best enjoyment.
"Liszt, I propose, let's have a drink for the cold beer!" Galtai raised his glass happily.
Liszt picked up the glass and responded: "Then let's drink cold beer."
"cheers!"
Gudong Gudong, the sound of swallowing beer was heard on the dining table.
…
kitchen.
On the table.
Irene kept flicking the ice cubes on the plate with a spoon, making a rattling sound.
Abby Tangshao couldn't help scolding: "Irene, stop making ugly noises, eat the ice cubes that the master rewarded you, hurry up!"
"Compared to eating ice cubes, I prefer to watch them melt, Mrs. Abbie, don't you think the temperature in the kitchen has dropped today?" Irene continued to fiddle with the ice cubes with four fingers, and looked at the seat next door The Lily bathe touched, "Little Lily, do you feel it?"
"Of course, each of us has ice cubes on our plates." After speaking, little Lily stuck out her tongue and licked the ice cubes in the spoon, she was reluctant to eat them all at once.
The ice cubes have no smell, but they are cool and comfortable, and the dryness and heat of the whole person subside.
Abby said angrily: "Little Lily, I don't allow you to talk to Irene during dinner, your clumsy and rude eating will only embarrass the kitchen!"
"Cough cough."
The housekeeper, Carter, bit the ice in his mouth hard. He was over fifty years old, but his teeth were still fine: "Mrs. Abbie, they are still children. Allow them to be a little rude when they are eating."
"Mr. Carter, I don't disobey your orders, but you shouldn't pamper them. They will be lawless. Clumsy is enough to disappoint people. If they can't learn a little manners, they will stay in the kitchen all their lives. Can't be the maid upstairs." Abby said seriously.
Carter and Mawson glanced at each other. They both knew that Abby was a good man with a tough mouth and a soft heart.
But Irene was obviously unconvinced: "Mrs. Abbie, I don't want to go upstairs. It's uncomfortable upstairs. I have to be careful not to leave any footprints. I will be a cook in the future, and I like working in the kitchen." .”
"You've got to die!" Abby frowned immediately, "With me in the kitchen, you'll never want to be a cook, little girl, remember, don't offend me!"
"But you will grow old one day."
"Even if I'm too old to work one day, the cook is still me now, you have to listen to what I say!"
