Zhu Cijiong took a closer look at the kerosene in the jar, it was indeed as clear as water, but the color was slightly darker, probably because of fractionation, and it was difficult to bring impurities up.

He nodded with satisfaction and said, "Well, this is very good, basically there are no impurities, and it can be used directly to light the lamp, just call it kerosene." This kerosene can be refined a little more and sold to the common people, so that the people who can't get the electric light can also have something to light at night. “

When Song Yingxing heard this, he was first excited, and then showed an embarrassed expression, he said carefully: "Your Majesty, this kerosene is not easy to preserve, if it is all packed in wine jars, I am afraid that ordinary people can't afford to buy such a large jar, do you want to make some small wine jars?" “

Zhu Cijiong took a look at the wine jar in front of him, this is even if it is fifty catties, the general wine jar is at least twenty or thirty catties, and no matter how small it is, it is rare, Song Yingxing said that it makes some sense to specialize in making some small wine jars.

However, it feels strange to use a wine jar to fill kerosene, if someone thinks it is wine and accidentally pours it into their mouths, it will be troublesome, Zhu Cijiong thought about it, shook his head and said: "No, you can't use a wine jar, you have to use a glass bottle." “

When Song Yingxing heard this, he looked confused, and he couldn't help asking, "Your Majesty, what is this glass bottle?" “

At this time, Daming had just produced glass, which was generally used to make telescopes, light bulbs and mirrors, and rich people would also buy them to make windows, and glass cups were very rare, and I don't know if anyone tried to make glass bottles.

Zhu Cijiong sometimes subconsciously confuses the things of the later generations with the things of this time, and glass bottles are naturally very common in later generations, but at this time in the Ming Dynasty, it seems that he has never seen glass bottles, he patted his forehead and said embarrassedly: "Do you have a study here, wait for me to draw one for you." “

Song Yingxing hurriedly nodded and said: "Some of them are on the top floor, but, Your Majesty, this kerosene doesn't seem to be very safe to burn, if the wick is not placed in a good position, it will burn violently, isn't it a bit dangerous to make lamp oil for ordinary people?" “

There is no kerosene lamp at this time, and the size of the fire is naturally difficult to control, Zhu Cijiong nodded and said: "Well, the kerosene-burning lamp should also be specially made, and I will draw it for you later." “

Song Yingxing originally thought about these problems, so he still had a headache for a while, not that he couldn't think of glass bottles or couldn't design kerosene lamps, glass bottles he could think of sooner or later, kerosene lamps could be designed sooner or later, but that was quite time-consuming, glass bottles are just upside down, kerosene lamps, you let people who have never seen it design out of thin air, and it is impossible to design a perfect finished product without a few years of repeated modifications.

Now, there is no need to think about the problem of storing and controlling the size of the lamp, as soon as the emperor makes a move, absolutely any problem can be solved.

At this point, the fifth floor can be regarded as almost over, Zhu Cijiong took the lead and walked to the steps leading to the sixth floor, and the rest should be gasoline, I don't know how Song Yingxing has refined it.

Puzzled, he hurried up to the sixth floor, where the temperature was about the same as outside, but the smell of gasoline filled the air.

This time, before he stretched out his head to look into the doorway, Song Yingxing directly arched his hand and said: "Your Majesty, if you don't think it's dirty inside, you can go in and take a look at this layer, this layer is ordinary water heating, and the water is not boiling, there is no danger." “

The water didn't boil, which meant that it was less than 100 degrees, so there was really no danger, Zhu Cijiong happily raised his feet and walked inside.

The inside of this layer is similar to the layout of the fifth floor, and it is also a huge iron can with a small iron can next to it, which should also be fractionated by the principle of fractionation, but there is a strange smell in addition to the smell of gasoline.

Zhu Cijiong sniffed it carefully, and it turned out to be the smell of gas!

He hurriedly swept around, and the window was open, but there were only two air vents in total with the door opening, so it would definitely not work, he hurriedly asked: "Chang Geng, do you smell this strange smell, do you know what this is?" “

When Song Yingxing heard this, he said embarrassedly: "This smell Weichen has already smelled it, it is emitted after the oil is heated, but Weichen doesn't know what it is." “

When Zhu Cijiong heard this, he reminded solemnly: "This is a gas that can be burned, if there is too much of this gas in a room, as long as one spark can cause an explosion, it is very dangerous, you can't arrange it like this, this house must open a few more windows, and a fan must be added to blow out, otherwise, once it accumulates for a long time, it is very likely to explode!" “

The emperor rarely spoke so seriously, Song Yingxing was so frightened that his face changed, and he hurriedly arched his hand and said: "Weichen is guilty, Weichen understands, change it later, change it later." “

Zhu Cijiong nodded, and carefully observed the facilities inside, he really was not a material for smelting, and he didn't know anything about petroleum refining, and he didn't see anything famous after looking at it.

Of course, he didn't want to understand the whole process of oil refining, but just wanted to take a closer look out of curiosity, and now that his curiosity was satisfied, the smell was really unpleasant, and he turned around inside, and couldn't help but raise his feet and walk out.

Song Yingxing saw that the emperor looked around expressionlessly, and then walked out without saying a word, thinking that the emperor was angry, he hurriedly followed, and said in fear: "Your Majesty, Weichen ......." “

Zhu Cijiong took a few breaths, raised his hand and said: "It's okay, I don't blame you, it's just that the smell of gas in it is too big, I'm a little unaccustomed to it, okay, those who don't know are not guilty, just pay attention to it in the future, take a look at this layer of refined things." “

When Song Yingxing heard this, he hurriedly asked people to get things, and at the same time secretly breathed a sigh of relief, fortunately, fortunately, the emperor was not angry.

Soon, the person on duty on this floor brought another wine jar, looking at his struggling appearance, I was afraid that there would be no fifty or sixty catties.

Zhu Cijiong couldn't help but step forward to take the sandbag pressed on the jar in person, and sniffed it gently, sure enough, it was gasoline, looking at the clear appearance inside, it was still relatively pure gasoline.

Zhu Cijiong nodded with satisfaction and said: "Very good, this is gasoline, specially for cars, you can send it directly to Wang Zheng and let him experiment with the new power plant, but it should be noted that you must not use an open flame to get close to gasoline, this gasoline does not need to be lit directly, a spark may cause an explosion, which is very dangerous." “

This Song Yingxing has a little understanding, because in the past small experiments, he tried to ignite the gasoline, but the fire did not touch the gasoline, and the gasoline ignited, but at that time, the amount he refined was very small, and it did not cause an explosion, but it just burned up with a bang, which scared him a lot.

Thinking of the scene at that time, he said with palpitations: "Weichen understands, the emperor can rest assured, Weichen will pay attention." “
