Chapter 88: 、 89

Xia Dacheng and Yang Tiezhu ran to several medical clinics in the town and reported the name of the saltpeter, and then Di Shuang matched up.
It's a pity that although the people in the medical hall knew that Dishuang was used for medical purposes, it was not used for too few uses, and there were no medical halls in Luoyun Town.
A doctor saw what they wanted, so he suggested that they go to the county to find it. After all, Luoyun Town is too small here, maybe it will be there in Huaihe County. Xia Dacheng had no choice but to discuss with Yang Tiezhu, asking him to go back to help the house first. He would go to the county and not to Yangcheng.
He is now in a hurry to go to the doctor, after all, La Wei Xian is now too much to do. It’s okay to stop doing it for two months, but at least one hundred or two silver dollars will be saved a month. What is the equivalent of a hundred and two silvers? It is equivalent to building a few more sets of three-bedroom houses, which is equivalent to ten acres of good land.
Now that I have found this thing in the hospital, I should go to a larger place and ask. Anyway, there are cars too, so people work harder.
Yang Tiezhu couldn't, so Xia Dacheng drove the car to the county alone, and then walked back by himself.
When Yang Tiezhu came back, Lin Qingwan asked him, only to know that Xia Dacheng had gone to the county.
Knowing that the people in the hospital knew this kind of thing, she was relieved. Since they all know it, they can definitely be bought, but Luoyun Town is too remote and too small to sell.
Lin Qingwan patiently waited in the room for two days before hearing the news of Xia Dacheng's return.
Xia Dacheng's face was darkened a lot after this time of running, and this time he came back to look even darker. He gave the things to Lin Qingwan, then turned around and went home to rest. In the past two days, I ran too many places, and it was completely supported. At this time, I must go back and have a good rest.
Seeing that Xia Dacheng didn't mention how expensive this thing was, Lin Qingwan knew that it was definitely within the cost range.
She asked Yang Tiezhu to get a small basin and a small pitcher, and asked him to fill them with water.
Yang Tiezhu brought the things, and she opened the small cloth bag Xia Dacheng gave her.
The small cloth bag is not big, it contains some crystalline white objects, which is about the size of a large soup bowl. Lin Qingwan didn't actually know this kind of thing, but she remembered that in several travel novels, it was said to be white crystalline objects, and now she can only try it.
She put the pitcher in a small basin filled with water, then grabbed a small handful of saltpeter and put it into the water. The saltpeter melted quickly in the water.
Yang Tiezhu stood there stupidly watching his wife experiment there. Seeing Lin Qingwan's dignified attitude, he did not dare to ask her why she did this.
After Lin Qingwan put saltpetre in the water, she sat aside and waited. After waiting for a while, she found that the water in the pitcher had not frozen.
Could it be that through the novel to trick her into reading less? Or is this crystalline object not the kind of saltpeter she said?
She tried to touch the water in the basin and the water in the pitcher with her fingers. It really felt cool to the touch. She had touched it when the water came in, and the temperature was a bit lower than just now.
Is it possible to put less saltpeter?
Lin Qingwan grabbed a small amount of saltpeter and threw it in.
After it was finished, her eyes were fixed on the water. Yang Tiezhu watched his daughter-in-law looking at the water so seriously, and stared at the water tank.
Then he saw a picture that surprised him--
A thin layer of ice formed on the water in the pitcher.
Yang Tiezhu held his breath, and Lin Qingwan also held his breath. After a while, all the water in the pitcher was frozen.
Yang Tiezhu couldn't believe it. He looked at his wife, Lin Qingwan smiled happily at him, and then he touched the ice in the pitcher.
Really ice? !
He was so excited that he couldn't speak, "Daughter-in-law, what's the matter? How could water become ice?"
Can Lin Qingwan tell him that the dissolution of saltpeter in the water will cause the water to cool down rapidly, and then cause freezing? Can she tell him that she also said in the novel? Certainly not, and he didn't understand it.
So she can only make up a pretense, "I don't understand this. That's how the big family I used to make ice."
After Yang Tiezhu listened, he nodded in excitement, then turned around and wanted to inform others.
Lin Qingwan held him so that he didn't worry, and brought the water in the small basin to the stove to boil it.
In fear that Yang Tiezhu would not be able to operate, she also followed.
Although Yang Tiezhu didn't understand why his wife did this, he thought she must have her own reason, so he started to boil the water honestly. There was not much water in the small pot, so it dried after a while on high fire, and then a layer of powdery crystal appeared at the bottom of the pot.
The appearance of the crystal is the same as the saltpeter Xia Dacheng gave her, but these should be finely broken.
Lin Qingwan was relieved and asked him to scrape off the crystals, fill the small basin with water, change a pitcher to fill it with water, and then put the scraped crystals into the small basin again.
Saltpeter can be reused, that is, the water in it needs to be evaporated to dryness by distillation, and then the crystals are scraped off and used again. Of course, it can not be used endlessly, and it will lose some each time, but it is very small.
It wasn't until the second ice making was successful that Lin Qingwan was completely relieved and asked Yang Tiezhu to notify Xia Dacheng to come over.
As soon as Xia Dacheng returned to the house and lay down, he was called by Yang Tiezhu. But looking at his cousin's excitement, you know there must be something wrong.
On the way, Yang Tiezhu whispered to Xia Dacheng about his daughter-in-law's making ice, and Xia Dacheng immediately started to run.
When he came to Yang Tiezhu's house, Lin Qingwan was still sitting at the table waiting for them. On the table were the small basin and the jug in the basin.
Xia Dacheng saw the ice inside at a glance and touched it excitedly.
It's really ice! Oh my!
Xia Dacheng calmed his excitement and sat down at the table.
"Is my younger sister looking for me to talk about the ice?" Her tone became a little unstable.
Lin Qingwan nodded, her eyes still a little dazed, she had been thinking about questions before they came in, and she still hadn't recovered a bit at this time.
She tapped her fingertips on her forehead and asked, "Where did Dacheng get these saltpeters? Is it easy to buy? Is it expensive?"
Smart people talk together to save trouble, and Xia Dacheng immediately understood what Lin Qingwan meant.
He thought about it in his mind, and then slowly replied: "I bought these ground creams in a big pharmacy in the county. It's not a medical center, or a place that supplies medicinal herbs to major medical centers. Also. Thanks to a friend of mine, I was able to buy this thing there, because other people don’t sell it in small quantities. It’s not expensive. It cost almost two taels of silver. As for whether it is good to buy, I also asked the shopkeeper in the pharmacy. , It’s said that the amount of this thing is not much, so the stock is very small. The stock I got back is almost all the stock in their pharmacy. So—"
Therefore, this method of making ice to make money is not desirable. Even if Xia Dacheng didn't finish speaking, Lin Qingwan understood what he meant.
She sighed slightly and said: "It's okay. After this lesson, let's dig an ice cellar to store ice in winter for the next year. This method can only be used in emergency situations."
Xia Dacheng nodded, he also had this idea.
but--
"The younger brother and sister, can this ice support us to store the freshness of wax?" When he said this, Xia Dacheng's heart was pounding.
How could he forget that storing dried laxian requires a lot of ice, so what can such a small crockpot do?
Lin Qingwan glanced at the jug embarrassedly and nodded.
"Should be barely able, I will think about it again."
After Xia Dacheng relaxed, he went back again.
Lin Qingwan said that she was tired and was going to lie down for a while, and then told Yang Tiezhu to go to Carpenter Cui to make a few wooden boxes out of them. They didn't need to look good, as long as they had a strong cover and sealed them, let him make them as soon as possible.
After Yang Tiezhu helped his wife in and lay down, he went out to find Carpenter Cui.
...
Carpenter Cui was quick, and after hearing what Yang Tiezhu said, he drove two wooden boxes out the next day. I didn't even paint, just a box with a lid and a buckle.
Yang Tiezhu brought it back to Lin Qingwan, and Lin Qingwan was very satisfied.
She took out a few more beds that she made for the baby's baby quilt, the quilt was small, and one bed was just padded. She simply put two more beds in, and then put the bowls of ice she made in the morning, including the bowls with ice, into the box. After putting it in, I was worried, and there were two small quilts on it.
Fortunately, she didn't have much hands and feet at the beginning, and she always felt that she didn't make enough things for her children. She was made into 5 or 6 beds, which came in handy now.
Lin Qingwan didn't care if she covered the box. Seeing Yang Tiezhu's curious look, she told him not to move this. At noon, she will look again.
Although Yang Tiezhu was curious, he listened to his wife's words and didn't do anything to watch.
After eating at noon, Lin Qingwan opened the box and took a look.
The box is strong, the coating is strong, and the ice inside is even stronger, and there is no trace of melting.
She put the bag away and covered the box again. Yang Tiezhu, who was watching from the side, was stunned, but he also knew that this was something about the preservation of the freshly preserved wax, so he didn't come over curiously to reveal it for a while.
In the afternoon, Lin Qingwan came over to take a look again. At this time, the ice showed signs of melting. A thin layer of water had melted on the bowl, but there was still a lot of ice.
In the evening, she looked again, and the ice in the box still showed no signs of drastically melting, and she was really relieved.
Yang Tiezhu was also nearby.
At noon, he was just guessing, but he thought for a long time without a conclusion. It was not until this time that he understood what his wife meant.
"Daughter-in-law, how did you know that putting a quilt in a box can slow the melting of the ice?" Yang Tiezhu was so excited at this moment that all this was so amazing. Shouldn't it be the hotter and the hotter it turns, the faster it turns?
Lin Qingwan rolled her eyes in her heart. Can she tell him that when he was a child, he used to watch people selling popsicles by using wooden boxes with quilts to keep them warm? Later, with foam boxes, this old-fashioned one was replaced. However, later refrigerators and freezers were greatly promoted and became cheap items, and then even foam boxes were eliminated.
Insulation can not only keep high temperature, but also keep low temperature. There is no foam box, but the principle is still the same, right? It is nothing more than sealing and insulation.
I can't tell my man the truth, I can only tell him that the big family where she stayed before did this. Then he pretended to be impatient and urged him to quickly let Carpenter Cui rush out the wooden boxes, and then ask the women who know how to needlework at home to quickly take out some cotton cloth and make some small quilts.
The quilt of her doll was just taken out for testing, but she had no plans to contribute. After all, these fabrics are all good materials, just use bad fabrics for small quilts for heat preservation.
Yang Tiezhu scratched his head, thinking that the family that Wanwan had stayed with was so amazing and could do everything, so he kept busy going under his feet.
Several women in the family hurriedly drove out a bunch of small quilts one afternoon and one night. In the middle, Yang Tiezhu went to the town to buy a bunch of coarse cloth and cotton.
Yang Tiezhu was busy outside and ran back to make ice cubes. Lin Qingwan explained the steps in the middle clearly to him, so he did it smoothly.
Now the tools are simple, the basin of water at home is too small, he can only make a few bowls of ice at a time.
This time, Lin Qingwan was not asked to remind him, he was almost open, he decided to wait for Carpenter Cui to finish making wooden boxes, let him make a few larger wooden basins, not too deep, shallower, as long as the area is large enough Just put more ice bowls. But thinking of this, he feels that using a bowl of frozen ice is not good...
After thinking about it, he took out the ‘Practicing Board’ that Lin Qingwan made for him, and found a charcoal to draw on it.
Lin Qingwan slept in the room for a while, and found out why her man hadn't come back to sleep. Seeing the light on the other side of the hall, she got up and walked over. From a distance, I saw Yang Tiezhu's very serious little trick, holding a board while writing and drawing.
She took a closer look curiously and found that Yang Tiezhu had made a few patterns on the board. One is a large square frame framed by a small square frame, and the other is a large circle framed by a small circle. His strokes are very rusty, and the shapes he draws are crooked, but Lin Qingwan can still see the approximate shapes he draws.
Lin Qingwan stood beside him for a while before Yang Tiezhu realized.
"Hey, daughter-in-law, why are you not sleeping, why are you standing here?" Yang Tiezhu put down the board and charcoal in his hand, and when he saw that his hand was dark, he quickly picked up the cloth next to him and wiped it.
"I think you didn't come back to sleep either, just thinking about what are you doing? What are you painting?" Lin Qingwan raised her chin at the board.
Yang Tiezhu blushed and scratched his head and smiled, "I think our frozen basins and bowls are inconvenient, so I want to find Carpenter Cui to make some again. But if you don't tell others how they look like, how does he know? What do you do?"
Lin Qingwan nodded, with a smile in her eyes.
Good boy, know how to invent tools.
"Then you continue to think about it, I'll go to bed first, don't delay it too late." After speaking, he straightened his stomach and turned back to the house.
Man, you still don't hit him too much, although she already has a rough image of the object in her mind. However, since he tried so hard to use his mind to think for himself, then let him want to chant, she can't be a daughter-in-law, and everything runs ahead. Isn't that too much of a man's self-esteem? ! It's better to be hyperactive in your brain. After hyperactive, you will be more flexible.
Yang Tiezhu didn't touch his head until he heard the movement of the wife's wife lying down on the kang.
