I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

When Liu Tan returned to the study, Gun Gun had already found a comfortable place to spread out, like a bear blanket.

Liu Tan looked at it, then at Miao Rui who was carrying the panda lantern skeleton behind him, and decided to make another kind of lantern.

Otherwise, the speed at which he is doing here can't keep up with the speed of rolling destruction, and he is afraid that he will be pissed off.

Liu Tan thought for a while and decided to make a fish. During the process of making the fish, Gun Gun stood aside and gave bamboo shoots.

Basically, he's building a skeleton over there, rolling in the back: click, click, click.

He pasted paper on the skeleton, rolling behind: click, click, click.

After he finished the lampshade, the billowing was still there: click, click, click.

Liu Tan faced the eating and broadcasting scene directly, forced himself to be hungry, and finally threw the things away, squatted beside Gun Gun and started eating snacks, stroking the cat while eating snacks.

I don't know if it was because he was driven to eat too much. Liu Tan finished a plate of dim sum without knowing it. When he reached out to touch the plate and found that the plate was empty, he was completely dumbfounded.

He looked at Gun Gun, and deeply felt that he couldn't let Gun Gun be by his side when he was working in the future, otherwise when Lu Xuan came back, he might not know the fat person!

In the end, Liu Tan could only endure the pain and let Gun Gun be taken away, so he continued.

After finishing it, he found a very serious problem - this fish lamp, it is pure white.

In Liu Tan's imagination, the Lantern Festival should be a river of lights gathered by colorful lanterns, which is bright and brilliant at a glance.

It's a pity that the lanterns he made by himself ruthlessly shattered his idea. When he thinks that the city is full of white lights converging into a river, he feels a little bad all over, and it's too easy to think of bad things. For example, the city is full of plains and the like.

When it comes to coloring lanterns, the easiest ones are probably black and red, not to mention black, and red comes through cinnabar.

It's not that cinnabar can't be diluted into various red colors, but it's all one color and it doesn't look good at first glance.

For other colors, Liu Tan thought about it, even if he wanted to make so many colored lanterns with his own financial resources, he would be poor when he finished.

He thought for a while, now the paint is not very easy to find, but probably the easiest way is to dye the paper, anyway, it is not for real painting, any color can be found on plants, for example, you can use turmeric to try yellow, Indigo has existed for a long time, and it can be adjusted through color matching, and purple has the existence of comfrey.

After these colors are made, basically the simplest lantern can be made.

Red is the easiest to get, so he directly made a golden red koi, not to mention the whole body is red, the edges of the scales on the body are outlined with gold, and there are dots of gold dots in the middle. Of course, the gold is made of gold powder, anyway, he is rich and willful.

The effect was really good. Liu Tan admired it for a while, and then made a special oil lamp out of clay so that it could be placed inside the lampshade.

When Liu Tan was doing it, he specifically told him: "No one is allowed to speak out."

Others are fine, but Huo Guang can't let Huo Guang know, otherwise he will say he is playing with mud again.

After Liu Tan made a suitable oil lamp holder, the koi had just dried, and after covering it, it looked bright even in the daytime.

At night, when the oil lamp was lit inside, the whole goldfish radiated red light from the inside out, and had golden reflections on the outside, making it look very luxurious.

Liu Tan walked around feeling very satisfied, planning to go back and do something else, such as flowers.

Whether it was when Liu Che traveled to the northern border country or when the mutual market opened, the weather was already very cold, and the originally beautifully designed garden might not be so brilliant, but it should be able to add a lot of color if decorated with these lanterns.

Liu Tan put the koi lantern in the yard and went back to sleep, planning to design something else the next day.

As a result, when he opened his eyes the next day, he heard Miao Rui say cautiously: "Your Highness, that fish yesterday..."

Liu Tan was washing up at this time, and asked after listening, "Fish? What kind of fish? Oh, you said that fish lamp? What's wrong?"

Miao Rui said: "That fish lantern... burnt."

Surprised, Liu Tan took a mouthful of mouthwash and almost swallowed it. He quickly spit it out and asked, "Burn? Why did it burn?"

Miao Rui said: "There was no guard last night. When we found out, the lampshade was already on fire. Although we were rescued, we couldn't be rescued. I have already imprisoned everyone. What should His Highness do?"

Miao Rui knew that it was Liu Tan's brainchild, so he kept Liu Tan busy for several days, not to mention that the lamp base was made for a long time and then dried for two days, not to mention the lampshade, all of which were made by Liu Tan drawn with a pen.

Liu Tan woke up after washing up. He waved his hands and said, "No, let them go. It has nothing to do with them."

When he just woke up and didn't turn his head, his first reaction was naturally how could he burn?

After waking up, I remembered that the lampshade is made of paper, and it is very thin paper, and the inside of the lampshade is airtight. If the temperature is high, who will burn it if it does not burn?

Liu Tan asked someone to bring over the burnt koi lantern. The koi lantern looked nothing to do with the exquisite beauty of last night.

Even if it wasn't completely burned, more than half of it had been burned, and the remaining half had been blackened.

Liu Tan was not surprised, the main reason why he wanted to look at it was to look at the lamp holder below.

Needless to say, the lamp holder he made is quite strong. Although it was also burnt black, it just didn't look good on the outside, but there was nothing wrong with it inside.

Liu Tanchang let out a bit of worry. It is now known that ancient lanterns are basically paper lanterns, and the interior of the lanterns is also made of candle oil, so there is no problem. How to deal with those papers to prevent fire?

Leaving an opening to ensure air circulation does not seem to work. What if the lights are more vigorous due to the wind?

So it's best to work on paper. As for using other fireproof materials... it's okay, but if you want to make a lampshade, you can only use crystal.

He can afford it in Liu Che's palace, but he can only use it in the Longevity Palace. He also wants to make it a signature Lantern Festival!

He locked himself in the study room and held the burnt paper for a while, thinking that if he wanted to do something with the paper, it must not be done in the production process, it should be processed after the paper is finished.

That is to say, brush a layer of fireproof on the surface of the paper.

Fire prevention... Liu Tan suddenly remembered that when he was building his palace, the roof would be painted with a layer of tung oil after painting, on the one hand to fix the color and on the other hand to prevent fire.

Liu Tan immediately asked someone to get some paper and brush it with tung oil, and then test the fire resistance of the tung oil after it dries.

After brushing with tung oil, the paper becomes less transparent than before, but it is not only fireproof, but also water repellent.

In the process of making, just brush a layer of tung oil on the inside, then paint on the outside, and then apply a layer of tung oil after the painting is finished.

Liu Tan didn't do it himself this time, and let someone do it directly. As for what to do, he had already drawn the patterns.

After it is made, it is placed in the yard, because most of them are red, and it looks really prosperous.

Liu Tan held the lotus-shaped lantern excitedly and wanted to put it in the pool of the palace for a look, but as soon as it was put in, the lantern sank to the bottom without hesitation.

Only at this time did he realize that the bottom of the lantern is a clay lamp holder, which means that it is equivalent to adding a stone to the paper lantern, and it will not sink in water!

Miao Rui looked at Liu Tan cautiously and asked, "Your Highness doesn't like it?"

Liu Tan said very melancholy: "I made a mistake."

If the lantern wants to float on the water, it must be very light, or the whole must be made of paper.

It’s just that if this is the case, it’s not impossible to put an oil lamp inside, but it may not be safe enough, because the shape of the oil lamp makes it easy to overflow.

It is not impossible to change the shape, but the safest is probably the candle.

When Liu talked about this, he became even more melancholy. Now he has made oiled paper for the lanterns, and now he also needs to make candles.

In fact, it is not that there are no candles at this time, but they are very rare, so rare that even Liu Tan only has a few candles given to him by Liu Che.

Because the current candles are basically natural candles, which are secreted by white wax insects, so it goes without saying how precious they are.

It is obviously inappropriate to use such rare candles as lanterns, and the current candles will produce extremely heavy black smoke after being lit.

This leads to the fact that although candles are precious, no one actually likes to use them.

In later generations, paraffin wax was mainly used in making candles. However, paraffin wax is a by-product extracted from petroleum. It is definitely not available now, so there are only two choices-beeswax or animal fat.

For beeswax, bees need to be raised. In the current environment of the northern border country, it is completely impossible, but it is definitely a loss of money.

Why use candles when there are cheaper oil lamps?

Candles were basically only popularized in the Tang Dynasty, and they also appeared in the poems of literati, but the real promotion did not take place until the Ming and Qing Dynasties.

Because at that time, grease was gradually used to make candles, but even if the grease was used for food, it was much better than making candles, which basically could only be supplied to high-ranking officials and nobles.

It's just that Liu Tan has no good solution, so he can only start with grease. Anyway, he has money, so he will do it first.

If there is no way, you can also make the storage for the lamp oil into a closed oil tube, put a lamp rope in the middle, and put it in the form of a candle.

However, even if you use thin bamboo wood as a lamp tube, it still has a certain weight, which is far less easy than candles.

What's more, all the bamboos in the entire northern border country are in his panda garden, and he is going to grab the bamboos with GunGong, I'm afraid he's going to kill his coquettishness.

After much deliberation, Liu Tan still plans to start with oil. The big deal is to promote the aquaculture industry. The main reason why the aquaculture industry cannot be promoted now is that the animals are fed with natural food, and the growth time is also long. Most people have to invest in it before generating income. With huge amounts of money, this is a very difficult thing for most people.

Liu Tan didn't have a good idea, so he didn't think about it at all. He focused on the candle and began to think about how to make it with oil.

Grease is usually in a fluid state, and it will only solidify when the temperature is low, but that solidification is also soft, and it is far from reaching the level of a candle.

So it must be hardened by other means.

Liu Tan's first thought was to add alkali.

But after he added alkali to the oil to obtain hardened oil, he suddenly realized something, isn't this the legendary saponification?
