Yuan Jing has experienced two smear nights in the past two days, which made her feel very inconvenient. I've been wondering how to find a replacement for electric lights.

I thought about lighting a bonfire overnight, on the one hand, it costs firewood, and on the other hand, no one is watching, and the fire will go out on its own. Obviously, lighting a campfire overnight is not suitable for a solitary person like her.

Let's make a torch, and you need to hold it in your hand, so it's not convenient to hold it when you urinate or urinate. I still don't think it's appropriate. Moreover, the torch is easy to drop Mars, and if the falling Mars ignites flammable materials such as animal skins, it will be a big trouble. The practicality is also not high, and the security is not enough. Obviously not suitable for her either.

Yuan Jing pondered how to find something to replace the electric light, and generally walked around the house randomly. Before I knew it, I walked to the storage room where the bacon was kept. Seeing a skewer of golden bacon dripping with oil, I had a flash of inspiration. I thought I could make an oil lamp for lighting. Although oil lamp lighting is not as convenient as electric lamp, it is certainly much more reliable than campfire lighting and torch lighting.

Yuan Jing excitedly began to observe the oil droplets on the bacon of different beasts. According to various scientific and technological documents in the previous life, the oil used for lighting in ancient times was generally vegetable oil, because vegetable oil was in a liquid state and was not easy to condense, so it was more suitable for use as fuel for oil lamps. However, some non-condensing animal oils can also be used as fuel for oil lamps.

The raw material that Yuan Jing can squeeze out vegetable oil at hand is sunflower seeds, but the process of squeezing vegetable oil is too complicated, and it also requires more complex auxiliary tools. Therefore, the plan of making sunflower oil and then using sunflower oil to make oil lamps was rejected by Yuan Jing.

She still wants to try animal oil, after all, animal oil is easy to make, and if you are lucky, you can get oil that can be used as an oil lamp. Besides, even if the animal oil produced can't be used as lamp oil, Yuan Jing has no loss, because she can't make lamp oil, she can use it to eat.

After observing for a while, I adhered to the principle that I would rather kill mistakes than let go. Yuan Jing began to refine all the kinds of animal meat fat in the storeroom. A total of 23 different animal oils are refined. These beasts are yellow, brown, transparent, and have all kinds of colors, and some of them also exude bursts of oil fragrance, and Yuan Jing feels a little hungry. It doesn't matter if she can't make lamp oil, she can really eat it.

Swallowing her saliva, Yuan Jing still started the great business of making lamps.

In her previous life, Yuan Jing watched a lot of video materials for making oil lamps. Although the materials used and the steps used to make them vary, there are three things that are needed to make an oil lamp: the container for oil, the oil bleach, and the wick.

The container for oil is a stone bowl, and the cheap orc husband made a lot of stone bowls and put them in the storage room, so Yuan Jing can use them casually.

It's a lot harder to get oil bleaching. Oil bleaching not only needs to be light enough to float on oil, but it also needs to be difficult to burn so that it doesn't ignite by the wick.

Let's let go of this difficult oil drift for now.

Yuan Jing made the wick, found several animal skins with a texture similar to cotton and linen, cut them into strips, and then braided the animal skin strips into a twist shape, and tied them to get a simple wick. There are relatively few animal skins with a texture like cotton and linen, and there are only 3 kinds in total. After a while, Yuan Jing made three kinds of wicks.

If the oil is floating, Yuan Jing plans to go to the small river in the Black Canyon to have a look, because the materials floating on the water can float on the oil to a certain extent, of course, this is not necessarily accurate, because the density of the oil is smaller than the density of the water, and it may not be able to float on the oil if it can float on the water. Anyway, it's going to try your luck.

Maybe there will be the same luck as Huge picking up Shou Yuanguo.

Walking to the river, Yuan Jing first observed the surface of the river to see if there were any materials floating on the river.

To Yuan Jing's disappointment, there was nothing on the surface of the water except for the fish and shrimp swimming in the river.

Yuan Jing, who was in an irritable mood, couldn't help kicking her feet, but she didn't expect to kick a hard thing.

It hurts a little, but it's bearable. I was secretly relieved, my foot hurt a little, but fortunately I didn't fall. Don't dare to be so careless next time.

Yuan Jing suddenly became a little curious about the thing she kicked in.

Then he pulled the hard stuff out of the sand. This thing is the shell of a dead snail, the shape is the same as the purple sand teapot in the previous life, but it is much larger than the purple sand teapot, and it would be just right to use it to make an oil lamp.

Yuan Jing poured out the sand inside the snail shell, and then rinsed the snail shell with water from the river. After rinsing, Yuan Jing was pleasantly surprised to find that the structure of this snail body was really similar to the purple sand teapot in his previous life. There is a handle and spout, and the inside of the body is hollow. Just open the top of the pot and add a lid. The whole snail shell is the same as the purple sand teapot.

Yuan Jing patted her head, in fact, you can use this purple sand teapot-shaped snail shell to make an oil lamp, fill the body with oil, and then one end of the wick sticks out from the spout, and the simple version of the oil lamp is ready. The spout is equivalent to the effect of oil bleaching.

There's no need to look for any more materials to make oil bleaching.

It is good to learn from the experience of our predecessors in making oil lamps. But we must not be bound by the experience of our predecessors. Wouldn't it be better to use local materials and make oil lamps with ingenuity.

Yuan Jing couldn't help but praise her wit.

Yuan Jing brought a large animal skin bag, which was just enough to hold these teapot shells. In order to make the oil lamp test faster, Yuan Jing directly found dozens of identical teapot snail shells in the sandy land by the river.

The material of the teapot snail shell is similar to that of the shell, and it is much harder than the shell, so there is no need to worry about it being broken, so Yuan Jing threw these teapot snail shells into the animal skin bag and went home.

Back at her residence, Yuan Jing tried 23 different animal oils one by one, finding three animal oils that could burn like oil lamps.

In the case of wicks, the effect of wicks made of all three materials is similar. Yuan Jing didn't bother with the question of which wick to use.

In the scientific and technological literature of the previous generation, it was recorded that the flame of mixed oil combustion was relatively bright, and the burning time was longer.

Yuan Jing, who was doing the experiment, mixed three kinds of oil that can be used as lamp oil according to the proportion to make mixed oil, and observed the brightness and fuel consumption speed of the oil lamp. In the end, it was found that the mixed animal oil prepared by mixing No. 1 oil and No. 3 oil in a one-to-one ratio had the brightest burning flame and the least fuel consumption, and the most important thing was that this mixed animal oil would not make a sizzling sound when burning, nor would it emit green smoke, and it would not produce a pungent smell when burning.

Yuan Jing spent seven days experimenting, and then another two days making oil lamps and mixed animal oil. In the end, a total of 30 empty oil lamps and 150 catties of mixed animal oil were made. Yuan Jing named this mixed animal oil as snail oil, and the empty oil lamp as a snail shell lamp.
