Du's house, backyard.
Du Qi is now busy making ice cubes with the saltpeter he bought. Liu Jian stood aside nervously, with a look of awe on his face. In Liu Jian's view, it is impossible to make ice successfully on a hot day, which is too extraordinary.
At this moment, Du Qi has already arranged everything. He fetched a slightly larger wooden basin. Put half of the water in the wooden basin, and then take a smaller clay pot and fill it with water.
After finishing all this, Du Qicai took out the saltpeter he bought and threw the saltpetre into the water directly. When the saltpeter enters the water, it reacts with the water and quickly absorbs heat.
So much so that there was smoke rising from the clay pot. As the heat continued to be absorbed, it was visible to the naked eye that ice flowers had appeared in the clay pot. After a while, the water in the pot had already condensed into ice, exuding a bone-piercing chill.
This is the result of saltpeter.
In fact, even now, gunpowder has not been invented for the time being, and saltpeter, one of the raw materials of gunpowder, will not be banned, so the official use of saltpeter is small, and ordinary people can buy it. When gunpowder is invented, saltpeter, as one of the raw materials of gunpowder, will be controlled by the imperial court, and it will be impossible to sell it to ordinary people in large quantities.
Liu Jian stood aside, looking at the ice in the pot, with an incredulous expression on his face, and murmured: "My lord, how is this possible? How is it possible that a basin of water can directly turn into ice. Could it be, this is the celestial method of the lord?" No?"
"Of course not!"
Du Qi shook his head and replied, "It's just a trick, not worth mentioning."
The ice cubes in clay pots are in good condition.
Such ice cubes are drinkable. If you directly use the ice that condenses in the basin because saltpeter absorbs heat, it contains saltpeter and cannot be drunk.
Just like this, it is necessary to use clay pots in the basin.
However, this kind of ice making is not easy to make on a large scale, and it can only be made in small batches.
It is only enough for my own use.
Du Qi looked at the ice cubes made with a smile on his face. Because the condensed water turns into ice, it is not easy to take it out of the clay pot directly. After all, the expanding ice cubes are tightly attached to the edge of the clay pot.
Fortunately, the weather was hot, the sun was shining, and the temperature was extremely high. After a while, the ice cubes on the edge of the clay pot had begun to melt. As soon as the clay pot was picked up, the round ice cubes inside rolled out of the pot.
Du Qi asked Liu Jian to bring the saw, cleaned the saw, and quickly sawed the ice into pieces. Looking at the pieces of ice, Du Qi ordered: "Liu Jian, fetch some honey!"
"yes!"
Liu Jian came back with some honey.
Du Qi brought a cup, poured warm water into the cup, added some honey, and finally took out a few ice cubes and threw them into the cup. As the temperature of the ice cubes diffused, the temperature of this glass of water dropped in a short time, and it was already refreshingly sweet.
On this hot day, drinking a sip will refresh your heart.
Feel comfortable all over.
Seeing this, Liu Jian immediately followed suit. For him, this is extremely unusual. After he took a sip, he was astonished and said, "My lord, this ice water is really refreshing. In summer, having a glass of cool ice water is really refreshing. My lord, this ice water is so refreshing. Do you supply restaurants?"
"Can!"
Du Qi answered immediately.
He thought for a while and ordered: "Ice water can be flavored with honey. This is a way of doing it. In fact, in addition, you can also use the current fruit juice to taste. Just squeeze the fruit juice and mix it with ice cubes, the taste is the same. Absolutely perfect. Various styles are needed in restaurants, and such an arrangement will definitely prevail."
Liu Jian's eyes lit up when he heard it, and he said, "My lord is wise!"
Du Qi and Liu Jian drank a glass of ice water each, enjoying the coolness of the summer. While the two were drinking water, they saw a figure enter the courtyard gate.
The person who came was Li Yuan.
He brought Xiao Li in with an urgent look on his face. Li Yuan came to Du's house for a private visit. But as soon as he entered Du's house, he showed his identity, so that the servants in the house did not need to inform, and directly led the way to the backyard.
When Li Yuan saw Du Qi, he was a little puzzled when he saw that Du Qi was drinking water with a cup in his hand, and looked intoxicated and refreshed. On this hot day, when I put down a glass of water, my whole body is steaming, it is very uncomfortable, there is no comfort.
It's just that Li Yuan glanced to the side, saw the ice on the ground, and immediately widened his eyes.
Ice cubes!
Du Qi actually made ice cubes.
You need to know?, even with the background of the royal family, there are few ice cubes. After all, in this hot weather, even the ice cubes stored in the ice cellar are not easy to preserve. The ice cubes in this ice cellar are favored by the Tian family if they are occasionally rewarded to officials.
Li Yuan knew very well that although Du Qi was young, he was extremely good at making food. So when he saw Du Qi drinking happily, he knew it was not just ice water, and asked, "Du Erlang, what are you drinking?"
Du Qi's eyes widened, a little surprised.
Why is Li Yuan here?
In particular, Li Yuan, as the emperor of a country, came to Du's house unexpectedly, which was beyond people's expectations. He came back to his senses and said, "Your Majesty, I can't stand the hot weather, so I made some ice cubes. I added some honey to the ice water, and it tastes good. Your Majesty, would you like a glass?" ?¡±
"of course yes!"
Li Yuan answered without thinking.
Du Qi immediately mixed a glass of honey ice water for Li Yuan, handed it in front of Li Yuan, and said: "Your Majesty, please! But this honey water has ice cubes in it, so it is quite cold. You can drink less, but it is not advisable to drink too much . If you drink too much cold, it will easily irritate the spleen and stomach."
Li Yuan nodded and said, "I know!"
He picked up the cup and took a sip.
After taking a sip of ice water, the sweet taste of honey bloomed in the taste buds, and the cold honey water rolled in the stomach. Originally, Li Yuan came out of the palace, even though he was riding in a carriage, his whole body was hot and uncomfortable. But after taking this mouthful of cold honey, the whole person became comfortable from the inside out.
? The heat all over the body disappeared, and there was no discomfort at all, but comfort from the inside out.
Refreshing!
Li Yuan let out a long breath, took another sip, looked at Du Qi, and asked, "Du Erlang, it's not easy for you to make ice cubes, it's a fantastic idea. Add ice to honey water, This taste is even more extraordinary. But the ice cubes you made don't seem to be taken from the ice cellar, how did you make the ice cubes?"
Du Qi pointed to the ice cubes beside him and said, "Your Majesty, this is the ice cubes made by the kid. The secret recipe is also nearby."
Li Yuan didn't understand for a while, and asked, "Du Erlang, how do you make ice?"
Du Qidao: "Reporting to Your Majesty, the boy uses saltpeter to make ice. Add saltpeter to water to make ice cubes."
While talking, he took out some saltpeter, refilled the clay pot with water, put it in the basin, and then put in the saltpeter. As the saltpeter enters the water, for a while, the water mist rises, the saltpeter quickly absorbs energy, and ice flowers quickly appear in the water.
Further, it condenses into ice cubes.
After a while, the ice cubes formed.
After Li Yuan saw it, he was amazed and said, "Erlang, how did you learn about this ice-making method?"
Du Qi explained: "Reporting to Your Majesty, it was only recorded in an unknown ancient book. Before this kid, I didn't know whether this method was true or not. After all, I hadn't tried it. But now, it is a successful experiment. The method is indeed feasible.¡±
Upon hearing this, Li Yuan asked again: "Erlang, with your method, can ice be produced on a large scale?"
This is what Li Yuan expected.
If it is possible to make ice on a large scale, then on a hot day, you will not have to suffer from the heat.
"cannot!"
Du Qi shook his head and replied: "Your Majesty, on the one hand, to make large-scale ice, you must mix saltpeter with water, but the mixture of saltpeter and someone is inedible. On the other hand, large-scale ice-making requires There is also more water. To this extent, turning a large amount of water into ice cubes is not something that a few saltpeters can do, so it is very difficult. Now, it is only small-scale ice production.¡±
"well¡¡"
Li Yuan sighed.
If it is possible to make ice on a large scale, it will be of some use to Li Yuan. It's a pity that this is small-scale ice-making, and for Li Yuan, it has little use value.
Under such a premise, Li Yuan will not intervene. Du Qi can make it, that is Du Qi's ability. He doesn't care, and he doesn't bother to care. After all, Li Yuan's palace also has an ice cellar for storing ice cubes, and there is no shortage of ice cubes. (Remember the site URL: www.hlnovel.com - Didn't finish reading?
