Chapter 377 Saltpeter Ice Making
"Heat stroke! There is no cure!"
When doctors popularized heat stroke, public opinion suddenly changed.
"It turns out that excessive heat stroke can cause heat stroke, and once it occurs, you will almost die!"
"The second son of the old Liu family in Dongcheng died of heat back then. Now that I think about it, he probably got heat stroke!"
………………
Summer is hot, which is a period of high incidence of heat stroke. Whether in the past years or now, heat stroke and heat stroke are common in people around us.
Now that doctors have listed the causes, dangers, and even prevention measures, the people of the Song Dynasty have begun to pay attention to it.
Suddenly, the sales of Huoxiang Zhengqi Water soared, and many people kept some at home. Once they feel unwell in hot weather, they should take it immediately to prevent heat stroke.
After more people understand the dangers, they consciously avoid working under high temperatures, especially at noon when the sun is strongest, to prevent heat stroke.
The doctor's announcement caused a stir in the business community. The phenomenon of heat stroke made it difficult for merchants to recruit workers. In particular, the proposal of high-temperature subsidies aroused dissatisfaction among many merchants.
"What? Not only do I have to be unable to work for two and a half hours."
"You still need to issue high-temperature subsidies? Isn't this all money?"
According to the announcement of the Imperial Medical Office, workers cannot work for two and a half hours a day, so the working time of the workers is suddenly reduced by less than half. The same work that was completed in one day now takes at least two days to complete.
Not to mention the need to issue high-temperature subsidies, which also increased a lot of costs, which immediately made many stingy businessmen quite dissatisfied and complained one after another.
Moreover, following the doctor's announcement, many employees were dissatisfied with the original working environment, making it very difficult for merchants to recruit workers.
"What does Fan Taicheng mean by this? When will the Imperial Medical Office be able to issue orders!" A silk merchant asked quite dissatisfied.Silk reeling needs to be carried out in a high-temperature environment. If high-temperature subsidies are to be issued, they will be the first to be affected.
"That's right. Doctors only need to treat illnesses and save people. If they care about businesses, it's like a dog meddling in a mouse's own business."
Although merchants are oppressed, not everyone can step on them. In terms of status, doctors are not much better than merchants.Nowadays, doctors take the initiative to issue announcements, causing businessmen's costs to increase significantly.
"A dog stalks a mouse, I think you are short-sighted! Heat stroke and heat stroke are a matter of human life, so doctors cannot just sit idly by and ignore them," Fan Sanming shouted coldly.
The silk merchant was dissatisfied and said: "Fan Taicheng's casual words have greatly increased our costs, so he is not targeting us."
"What nonsense! Fan Taicheng is not targeting merchants, this is just a chance for you to show off!" Fan Sanming sneered.
"Give us a chance?" The silk merchant raised his eyebrows. Because of the doctor's announcement, he had to spend a lot more money, but Fan Taicheng actually gave him a chance to perform!It's simply confusing right and wrong.
Fan Sanming retorted: "Fan Taicheng and the Liao State jointly opened up the Silk Road on the road, and also proposed opening up the Maritime Silk Road. How much money has your silk industry made? Why are you not grateful to Fan Taicheng? Now you are only giving some poor women a little high-temperature subsidy." , you are just like killing your parents, you are simply ungrateful! No wonder the world looks down upon us and other merchants so much, it is because of you and other people like you!"
"We..." The silk merchant's expression changed and he wanted to retort.
Fan Sanming couldn't resist, and continued: "Also, how many people die from heat stroke in your silk reeling workshops every year, and how many people scold you for the dirty money you make, and those who are covered in silken clothes are not sericulture. Those female workers are not only If you can’t wear silk, you can’t even save your life.”
The silk merchant suddenly looked embarrassed, but was speechless to argue, because what Fan Sanming said was true. The silk reeling workshop needed to soften the silkworm cocoons with hot water. The temperature in the workshop was quite high, and there were cases of female workers dying of heatstroke every year.
"And you guys, you hire workers in Kaifeng City and work under the sun despite the high temperature. How many people suffer from heat stroke every year." Fan Sanming angrily yelled at a group of businessmen.
"We are not indifferent to human life, and we all bought Huoxiang Zhengqi Water." A businessman said with a stern expression.
Fan Sanming shook his head and said: "The Huoxiang Zhengqi water produced by Fan is supplied to the world at an affordable price. How can we not know the price? It only costs a few dollars. The Huoxiang Zhengqi water alone is not enough! Far from enough! We are waiting to change When the world evaluates merchants, they must pay attention to hired workers, otherwise once your workers repeatedly die of heat stroke, the reputation of merchants will be ruined, and you may be out of reach if you want to establish a Ministry of Commerce."
The expressions of many merchants changed. The status of merchants is low and they want to establish a Ministry of Commerce to change their status. If it is really revealed that merchants disregard the lives of their employees, the image of merchants will definitely plummet again.
"Besides, Fan Taicheng's move was out of good intentions. If an employee really dies of heat in your workshop, you will not be able to escape responsibility. You will at least have to pay a large sum of money and be held accountable by the government. In comparison, this A small amount of money is nothing, and it can restore the image of the merchant, so you won't lose anything." Fan Sanming said both softly and hard.
Other businessmen who did not need to pay high-temperature subsidies echoed in support of Fan Sanming.
"But I will wait for this money after all!" the silk merchant said dissatisfied.
Fan Sanming sneered and said: "If you refuse to provide high-temperature subsidies and at the same time allow human lives to occur in the workshop, which damages the image of the merchants, not only will we not help, let alone these goods with human lives on them."
"Not bad!" All the merchants nodded. Nowadays, establishing a commercial city is the top priority for merchants. If anyone ruins the efforts of merchants, they will naturally be ostracized by other merchants.
The expressions of many merchants changed. Fan Sanming's threat can be said to be their lifeline. Even if they increase high temperature subsidies or reduce working hours, they can earn less or increase prices as compensation.
If they are blocked by the entire industry, then they may have no way out except bankruptcy.
Now, as silk merchants and others compromise, industries that require high temperatures or work under the scorching sun are complying with doctors' regulations, no longer working during the hottest two and a half hours, and providing high-temperature subsidies during hot weather.
"Thank you Fan Taicheng!"
For a moment, countless employees cheered in unison. This was the first time someone spoke up for these coolies, allowing them to reduce the danger and get relatively more pay, giving them a rare chance to breathe and compensation.
........................
"hot!"
"Hot!"
This is the voice of everyone in Kaifeng City.
The summer of Shaosheng's fourth year was extremely hot, and the entire city of Kaifeng was like a steamer, enveloped in the scorching heat.
Because of an announcement from doctors, many people have been protected from the dangers of heat stroke and heat stroke. However, in addition to people who work in high temperatures, there is also a group of people who are extremely intolerable to the heat - and that is pregnant women! "
"Why is it so hot!"
Fan Fuzhong!Li Qingzhao was wearing a cool gauze with a big belly. Even though he was in the house, he still couldn't feel the slightest bit of coolness.
Fan Zheng explained: "Due to pregnancy and changes in the body, pregnant women often experience hotness and are more intolerant to heat than ordinary people. This is a very common phenomenon."
Li Qingzhao felt a little relieved and reached out to touch his bulging belly with a look of helplessness on his face.
"There should be some ice stored in the house. When Lian'er gets it, it will be cooler." Fan Zheng comforted him.
There are no ways to escape the heat in Kaifeng City, and ice is one of them.
However, the ice of this era was not as simple as that of later generations. Instead, an ice cellar had to be dug underground in advance. In winter, the thick ice cubes in the Bianhe River were cut and then transported to Kaifeng City, where the ice cellar was placed and sealed.Wait until the hottest time in summer, then open the ice cellar and take out the ice stored in it to escape the heat. However, this method is time-consuming and labor-intensive, and the losses are considerable. Naturally, ordinary people cannot enjoy this kind of treatment. Only wealthy people can have the opportunity. Enjoy.
Naturally, Fan Mansion also has an ice cellar with ice cubes stored in it. In order to take care of the pregnant Li Qingzhao, all the ice cubes in Fan Mansion were supplied to Li Qingzhao.
"Miss, there is no more ice in the house." At this moment, Lian'er hurriedly came to report bad news.
"It's gone so soon?" Fan Zheng frowned.
Lian'er said helplessly: "My uncle doesn't know something. Miss feels stuffy when the weather is hot, so she uses ice cubes. In addition, it is too hot this year, and the ice storage in the house has been lost. Now the ice storage in the house has melted."
Fan Zheng couldn't help but sigh. This summer was indeed a little unusually hot. He stood up and said, "Then I'll borrow some ice from other mansions."
"Hey! Forget it, you are a dignified evil doctor Fan Zheng. If word spreads that you are using ice as a concubine, wouldn't it make people laugh at us? Besides, the weather is hot now, and there will not be much ice in other houses. ." Li Qingzhao quickly dissuaded him.
Fan Zheng turned around helplessly and came back. At this time, there really wasn't much ice left, and even if he borrowed it, he probably wouldn't be able to borrow much.
"Then let me fan you!"
At the moment, Fan Zheng picked up the cattail leaf fan and fanned Li Qingzhao.
However, the weather is so hot now that even the wind blown by a fan is still hot. What's more, Li Qingzhao is pregnant and cannot use the fan for a long time.
"Miss, uncle, this is cold water from the well. You two should wash your faces first!" Lian'er was busy sweating and fetching a basin of cold well water from outside the house.
Fan Zheng and Li Qingzhao simply washed their faces and felt a little bit cooler.
"It would be great if it was winter! It's cold in winter and you can still light the stove, but if there is no ice in summer, you will have to suffer." Li Qingzhao sighed.Especially since she is pregnant, she not only feels hotter, but also cannot use cold water regularly. Once she lacks ice cubes, she can only endure the high temperature.
"ice!"
Fan Zheng sighed in his heart, summer air conditioners were the main force in later generations, but not like those in the Song Dynasty...
No, ice was not used in later generations. At that moment, Fan Zheng suddenly had an idea and thought of the method of making ice in later generations, using saltpeter to make ice!
"I have a way to make ice!" Fan Zheng jumped up and said excitedly.
"Mr., don't be ridiculous. It's summer, and it's scorching hot. How can we make ice in today's hot weather." Li Qingzhao looked at her husband and felt that Fan was confused by the heat.
Fan Zheng said solemnly, "Yes, I will personally perform a magic trick for my wife today, making ice in the summer!"
At that moment, Fan Zheng immediately ordered a batch of saltpeter for making gunpowder from the Ordnance Supervision. At the same time, Fan Zheng asked Lian'er to fetch more water, and found two copper basins, one large and one small.
"Can this make ice?" Li Qingzhao asked puzzledly.
Fan Zheng said proudly: "Fan's evil methods have never failed!"
Li Qingzhao couldn't help but laugh angrily, looking helplessly at Fan Zheng's proud look.
I saw Fan Zheng putting a large bag of saltpeter into the water in the huge copper basin. Soon, the saltpeter dissolved in the water, and then he put the small copper basin into clean water.
"This is over!" Li Qingzhao opened his eyes wide, ready to witness Fan Zheng's evil recipe with his own eyes, but he only saw such simple steps.
Fan Zheng nodded and said, "Yes, it's that simple."
Next, as Fan Zheng continued to put saltpeter into the large copper basin, the whole room slowly became cooler.
"It's really not hot anymore!" Li Qingzhao said in surprise.
"This copper basin is also cold." Lian'er stepped forward and touched the copper basin. She suddenly felt a chill and couldn't help but said in surprise.
Fan Zheng said proudly: "The reason why I chose to use a copper basin is because the purpose of making ice is to cool down, and adding saltpeter can lower the water temperature and also keep the entire room cool."
"What if you want ice?" Li Qingzhao said excitedly.
Fan Zheng had already made the whole room extremely cool. The method of using saltpeter to make ice was correct. If it continued to get colder, wouldn't it be possible to make ice?
"Ice making in summer!" Lian'er said impatiently.
Fan Zheng chuckled and said, "It's very easy to make ice. Just cover the copper basin with a thick quilt!"
"Put on a thick quilt!" The two girls looked at Fan Zheng in disbelief. If this advice didn't come from Fan Zheng, I believe no one would believe it. It would be even hotter if you covered yourself with a thick quilt in the summer, and Fan Zheng actually wanted to Cover the copper basin with a thick quilt and use saltpeter to make ice.
Fan Zheng explained: "The reason why the quilt can keep warm is not because it can block the cold air outside, which means that the cold air cannot penetrate the quilt at all. In this case, if we use the quilt to cover the cold air, it will naturally not float away. As long as we continue to join Saltpeter can certainly be used to make ice in summer."
"My uncle has another evil recipe?" Lian'er said playfully.
Li Qingzhao shook his head and said: "No! What my husband has given is a correct method, but it's just that it is not understood by the world, so will it be called an evil method?"
"Madam, you know me!" Fan Zheng said with emotion.
Fan Zheng and Li Qingzhao looked at each other and immediately understood each other.
"I'm going to make ice according to the young master's method!"
Lian'er suddenly felt uncomfortable all over. Even in a cool room, she felt restless. At that moment, she immediately walked out of the room.
"Husband!"
In the room, Li Qingzhao fell into Fan Zheng's arms with blurred eyes. Because of her pregnancy and the hot weather, she and Fan Zheng felt uncomfortable even being next to each other.
Nowadays, with the use of saltpeter ice to cool down, the body's hotness is swept away, but the body's hotness cannot be eliminated.
Fan Zheng felt Li Qingzhao's plump body, and his hands gradually became unreliable.
"Doctor Zhang said that three months before and after is not enough, but three months in between is fine!" Li Qingzhao whispered in a low voice.
Ordinary officials have three wives and four concubines, but Fan Zheng only has one wife. These past few months have made Fan Zheng very frustrated and ready to make up for him.
At that moment, Fan Zheng no longer had any worries, the curtain fell quietly, and there were gasps in the room. (End of chapter)
