Chapter 378 Making Ice with Saltpeter (Thanks for the monthly ticket of 20191629)
"Making ice cubes? Your Highness Sean, did you invite a water magician?" Sophia looked puzzled.

Water mages can make ice cubes, like Vivienne.

But making ice cubes requires a lot of mana, and ice cubes can't be sold at high prices, so few water magicians are willing to make ice cubes in large quantities, and only occasionally sell some to nobles who are not short of money.

But what does it have to do with water magicians creating ice cubes and saltpeter?
Sophia waited quietly for Sean to continue.

……

"No, we can make ice cubes without the participation of water magicians. The answer is to use saltpeter." Sean replied.

"But Your Highness Sean," Sophia raised her hand: "Isn't saltpeter used to make gunpowder?"

"It can make both gunpowder and ice, so saltpeter is a treasure."

While explaining, Xiao En ordered the Silver Hand recruits to find an iron basin and a large wooden barrel.

The wooden barrel is a bucket used by residents in the town to hold drinking water. It is about half the height of Sean and has a diameter of sixty to seventy centimeters.

Sean asked the two soldiers to fill the barrel with a quarter of water, and then put saltpeter into the water.

……

After the saltpeter dissolved in water, it began to absorb a lot of heat. The two soldiers also found two wooden sticks and kept stirring to speed up the dissolution of the saltpeter.

But Sean still felt that the saltpeter was dissolving too slowly, so he secretly used magic power to control the violent activities of the water molecules in the bucket to speed up the dissolution.

In just 5 minutes, a layer of fine water droplets appeared on the outer wall of the wooden barrel, white water vapor also appeared on the water surface in the wooden barrel, and ice slag gradually began to condense on the water surface.

Sophia still didn't quite believe that saltpeter could make ice cubes at the beginning. If saltpeter could make ice, then this kind of ore must have been famous a long time ago. How could it be unknown until now?

But seeing this scene, Sophia's eyes widened in surprise.

What His Royal Highness Sean said is true!Saltpeter can indeed make ice cubes!
……

She stepped forward and touched the wall of the barrel covered with water drops. Her tentacles were extremely cold. Sophia couldn't help but exclaimed:

"I didn't expect that melting saltpeter in water can achieve such an effect! No wonder Your Highness Xiao En wants to collect saltpeter on a large scale. If you can produce a large amount of ice cubes, it will be good news for people in the hot summer!"

At the same time, Sophia also asked curiously: "But Your Highness, how did you know where the saltpeter is and that it can be used to make ice cubes?"

There has never been saltpeter in the Principality of Ryan before. Her father Olga dug the saltpeter mine behind the coastal plateau according to Sean's instructions. How did His Royal Highness Sean know the specific location and nature of saltpeter?

"Of course I was guided by the God of Light." Sean perfunctory, and then continued: "Okay, let's try to make ice cream!"

At the same time, Sean also said to Windsor: "But this is the first time to make it after all. The raw materials are not enough, and the taste is not up to expectations. You have to be mentally prepared."

"It's okay. I just didn't expect ice cream to be made so easily! I thought ice cream was a dwarf's high-tech product!" Wen De Sole laughed.

Seeing that Sean had made ice cubes, the steps behind making ice cream were very simple. Windsor just didn't expect that the ice making process was so simple.

Sean ordered the Silver Hand recruits to go to the castle kitchen to get some milk powder, sucrose and glutinous rice flour, put them into a clean iron basin according to the ratio, add water and stir.

It is worth mentioning that sucrose and glutinous rice flour are both luxury goods in the Principality of Ryan.If you want to sell ice cream on a large scale in the future, it is better to replace it with honey and cornmeal.

After stirring, Sean put the iron basin into the wooden barrel that was about to freeze.

After a while, when ice forms in the basin, the "ice cream" is ready.

Although the heat conduction performance of the iron basin is very good, the whole process is just a heat transfer process, and Sean can't do much. The freezing time in the iron basin is too slow.

After waiting for 5 minutes, Sean saw that there was no sign of ice condensing in the iron basin, so he didn't wait at all, and directly distributed the ice-water mixture of the ice cream to Wen Desuo and Sofia:

"It will be ice cream when it freezes completely, but it will take a long time. You should try these first. It can also be called a 'cold drink' now."

Sophia took the "cold drink" and tasted it. It was ice cold, and it really felt good to drink in summer.

"It feels very good to drink this place in summer. Of course, for mercenaries, they prefer cold beer."

"You have reminded me!" Sean nodded: "We don't have to stick to making ice cream. Cold beer, cold watermelon and other fruits can also be sold well. By the way, Sofia, are you willing to go to Port Capul with me? ? All the expenses on your way will be charged to me."

Facing Sean's sudden invitation, Sophia was taken aback, but she replied immediately: "Of course I would!"

"Okay then, you go and prepare, we will set off in two days."

"Okay, Your Highness Sean. Then I'll go back first!" Sophia bid farewell to Sean.

After Sophia left, Windsor said to Sean: "My lord, the ice cream in my memory is not only like this, but there is also a better one, which should contain eggs and cream."

"Oh, that's another way of making ice cream. We'll try it out later. Wen De Sole, you go and do it first. I'm fine here alone."

"Okay sir." Windsor said goodbye to Sean and left without asking anything.

However, Windsor is indeed very busy, and he will go to Port Kapoor tomorrow, and he still has a lot of things to prepare.

After Windsor and Sophia left, Sean continued to make some ice cubes with saltpeter and threw them into the [Dimensional Backpack].

With the help of saltpeter, ice cubes that used to cost a lot of mana can now be made with very little mana.

These ice cubes can be saved for a rainy day.

……

After finishing his work, Sean returned to the castle study and began to read a book, quietly waiting for the night to fall.

After dinner, Sean went to the basement. This was the time to communicate with Khadgar through a note.

But today is quite special. Sean broke through level 30 today, and many major events happened in the territory. that end.

Khadgar also quickly got out from the portal and came to Sean.

"My lord, congratulations on your promotion to the silver rank!" Khadgar congratulated Sean.

"Khadgar, I became a mage after breaking through to the silver rank, can you teach me to have the 'raven form?'"

Sean has been coveting Khadgar's transformation skills for a long time.
