Returning to the Pastoral: Mrs. Yipin

Chapter 189 Saltpeter Ice Making
The method of making ice with saltpeter is actually not new, as long as anyone who has received some education in modern times will know it.When Su Yun was studying, his chemistry teacher also talked about how the ancients discovered this phenomenon and then used it.

The teacher cited this example not only to deepen the impression, but also to make the boring chemistry class more interesting.And this is indeed a very interesting thing for the students. For example, Miss Su, who was in fashion for a while, wrote it down.

Now this knowledge point can come in handy.

After Mr. Sun's announcement, Su Yun immediately found Wang Xi. After explaining his intention, Wang Xi also seemed very surprised.Obviously, in the original Chinese history, due to the use of firearms, saltpeter was developed in large quantities. By the Song Dynasty, saltpeter ice production had developed to a certain extent.

But it is obviously still a new thing in this country called Daliang.

According to Su Yun's rough estimate, Daliang's technology should be similar to that of the Five Dynasties and Ten Kingdoms period in Chinese history.Firearms have just started, and it is normal to have not discovered the characteristic of saltpeter frosting for the time being.

Or, even if they saw it, no one went to the bottom of it.

"Can this really make ice?"

Wang Xi was a little shocked. Leaving aside how magical this thing is, let's talk about it. In this scorching summer, Fuyun Building consumes a lot of ice cubes every day, which is a huge expense.

Although the ice is harvested in winter, it is a lot of money to build an ice cellar and maintain it!
Immediately, he recruited a guy, took out his name card, whispered a few words, and the guy ran away quickly.

Su Yun also took the opportunity to go into Fuyun Tower to rest for a while, and also enjoyed a bowl of iced sour plum soup.

After eating a bowl of iced sour plum soup, the man became much more energetic, and after chatting with Wang Xi for a while, the young man came up to reciprocate.

As a result, when Su Yun and the others went downstairs to take a look, Su Yun almost died of fright.

He looked at Wang Xi, but saw that he was taking it for granted, and couldn't help but click his tongue secretly.

Fuyun Building is really rich and powerful!

This is to get all the saltpeter in the city, right?Or did he know some mine owner who opened a saltpeter mine?

"Back to the big shopkeeper, my master said that there is only so much saltpeter that can be allocated for the time being."

Wang Xi nodded, and said: "The Mid-Autumn Festival will be in a month or so, and there will be many people who customize fireworks. Go back and report to your master, and say that his Qingfu Yunlou has received it, and you will be greatly thanked in the future. "

"Yes, Shopkeeper Wang!" The visitor clasped his fists and said, "If there is nothing else to do, please excuse me first..."

Wang Xi nodded, watched the boy from the firework shop leave, and then asked: "Have you prepared everything Miss Su wants?"

"Get ready, Shopkeeper Wang!"

A group of people entered a hut, and there was a large tank with half of the water in it, and a small basin on the water, which also contained some water. The guys unloaded the tank from the car. The saltpeter was moved in, and under Su Yun's command, the saltpeter was poured into the tank and stirred continuously. After a short while, the water in the small basin froze.

All the people stared dumbfounded at this scene that looked like a magic trick, and they couldn't help but wonder, what kind of trick is it if it's not the magic of the fairy family?
After Wang Xi was surprised, his eyes lit up. How many ice cubes could this cart of saltpeter produce in a day?It can be used repeatedly. The summer sun is cheap and the most poisonous. Put it in the sun and wait for the gouache to evaporate. Wouldn’t it be possible to use it to make ice again?In addition to using some water in the later stage, it is simply a cost-free operation!
Thinking of this, Wang Xi's heart became hot, and he immediately recruited a buddy to buy saltpeter from the fireworks shop. As for how to keep these treasures, there is no need to worry, the buddy of the fireworks shop has already mentioned it.

Even Su Yun was educated about how to preserve saltpeter.

"Go, take the old man's name card, and go to all the places in the city that can receive saltpeter."

While Wang Xi was giving instructions, he directed the young man, "Give half of the saltpeter in this cart to Young Lady Su, and help others to load it onto the cart."

"Ah!" Su Yun let out a soft cry, and said, "Shopkeeper Wang, we don't need this much land for our own use."

However, Wang Xi chuckled and said, "It's very hot this day, there's not enough saltpeter to make ice, and it will take at least a day to expose it to the sun, so you can use it first."

After a pause, he said with a smile: "Don't mention money to me, that would be boring! Tsk tsk, young lady Su, you are really a god, and only you can do such things as turning decay into magic. You But it helped Fuyun Building a lot!"

"Where, where..." Su Yun said modestly, "San Niang heard this from her deceased husband. Where can I get any credit?"

"It's the same, it's all the same!" Although Wang Xi didn't believe it in his heart, he believed that Su Yun was a magical person anyway.As for why she said that, he could guess one or two.

But this has nothing to do with him. People who do business are always smooth, and the other party can continue to bring benefits to themselves, so why bother to expose others?
This person lives for a lifetime, how can he not have a difficult time?As long as they have a good partnership with their Fuyun Building right now, it will be fine.

By the way, this little lady is really ingenious, the pickled peppers and sour bamboo shoots, all kinds of weeds on the mountain were played by her, and she gave her a wild name, which became the object of pursuit of the nobles.

Although there are a lot of wild things these days, it is something new to deliberately put this name on them.Customers who come to Fuyun Building don't care about money at all. What they care about is whether everything here is worthy of their status and whether it can make them stand out.

In the spring, the wild celery sent by Su Yun, under Su Yun's suggestion, was labeled as a gift from the mountain, which made the ordinary things immediately have an extraordinary value, and became a gift for the nobles. A sought-after dish.

A concept change, ordinary things, even things that are not even in the eyes of those nobles on weekdays have become objects of pursuit.

This Su Sanniang, I really can't tell.Not only is he ingenious, but he even has a bit of thought in the way of business. Such a character is definitely worth putting down his body to make friends with.

Hearing what Wang Xi said, Su Yun stopped being polite, and said, "Then thank you, Shopkeeper Wang!"

"Miss Su, you are welcome. Use these first, and I will send someone to bring you some in a few days. It is hot today, brother at home, the girls are studying hard, and eating some iced sour plum soup is also good for cooling off the heat." .”

Su Yun nodded and smiled, then chatted for a few words, and then bid farewell to Wang Xi.

More than half of the carriage has been occupied by saltpeter, and Su Yun also felt that the carriage was too stuffy, so he simply put on a straw hat and sat in front of the carriage with Lu Da, thinking that he would be home to make ice cubes soon, so he was quite upset for excitement.

In this ancient times, what is more fun than improving living conditions?
PS: I feel so tired these days, I'll take a break and try to see if I can do four shifts today, and if I can't, I have to keep three shifts...
