Chapter 430 This is a micro-carving tool (please vote and subscribe)
"Haha, that's right, this thing is used to magnify things, but it only makes things look bigger, it can't magnify the real thing, just like your hand, what you see through this tool is magnified, and it remains the same without the tool." Luo Chong explained.
"Chief, what is this thing called, and what can it be used for? If it can only make things look bigger, it seems useless. If it can turn a bowl of rice into a real big bowl of rice, how great it would be. Isn't it annoying that it only looks bigger?" Da Zui suddenly felt that this magical thing was useless.
"Haha, your idea is unique, but there is no such thing as a free lunch. Even if there is, it must be poisonous. Food is grown. If you can use this magnifying glass to make it more, who will work? Just make magnifying glasses.
This tool called a magnifying glass is not useless as you said. Didn't you say it yourself? It can magnify things and let us see more clearly. This is already very useful.
Think about it, if I ask you to cast a copper ware with very fine patterns, but you can't see it clearly at all, what should I do?
But if you have a magnifying glass, it will be different. You can use it to carve a mold, can't you see more clearly and see smaller things?
By the way, this magnifying glass has another use. It can be used to focus the sunlight in the sky to a point. The temperature of that point is very high. Although it can't melt metal, it can ignite wood chips. So as long as there is such a magnifying glass, it can be used to light a fire on a sunny day." Luo Chong explained to them again.
"What? This thing can also start a fire from the sky?!" An apprentice exclaimed.
In their opinion, the fire from the sky is the fire ignited by the lightning that hits the trees, but they have never heard of the spontaneous combustion of trees under the sunlight.
At this time, they heard Luo Chong say that this transparent round plate can ignite the fire from the sky, and they all felt very incredible.
"No, it's not the fire from the sky, but the light of the sun. Do you feel very hot when you bask in the sun in the summer, as if you were roasted by fire?" Luo Chong asked, and they nodded in cooperation .
"Yes, that means the sunlight has temperature, and the sunlight can heat things, right?"
Luo Chong continued to guide their thinking. After thinking about it, several people nodded again.
"The magnifying glass can gather the sunlight shining on it to a very small point, that is to say, the temperature of the sunlight will also gather to a point, so this point will become very hot, so hot that it can ignite the wood." Luo Chong concluded.
However, several people still only understood half of what they heard, and they looked confused. Obviously, the refraction of light has exceeded their daily thinking range.
"Well, now it's afternoon, and the sun is at its hottest outside. Let's use this magnifying glass to test how to light a fire, and then you'll understand." Luo Chong suggested.
Several people were immediately excited. This is a fire from heaven. Did the leader invite them to witness a miracle together? This is such an honor.
Da Zui immediately took a few pieces of firewood, and the other two apprentices also took a handful of charcoal, and followed Luo Chong out of the shed.
"I say, do you still want to roast a fire outside, or do you plan to cook outside? Aren't you afraid of the heat? Why take so much firewood? A small piece of wood will be enough." Luo Chong held his forehead with one hand and said speechlessly.
Several people then threw away the things in their hands in embarrassment, leaving only Da Zui holding a piece of charcoal and a piece of firewood.
They came under the scorching sun, just after the middle of the afternoon, which was the hottest time of the day. Luo Chong took the charcoal and rubbed it on the firewood, rubbing it black, after all, black absorbs heat better, and then began to fiddle with the magnifying glass under the gaze of several people.
He held the magnifying glass up at an angle, pointed the mirror at the sun, and then adjusted the focus up and down. Several people soon saw that as Luo Chong moved the magnifying glass, a bright spot of light immediately appeared in the shadow on the ground.
This spot of light was very large and bright, but as Luo Chong lowered the magnifying glass, the spot of light began to shrink, but it became brighter, until it shrank to the size of a soybean, the spot of light was extremely bright, and it was impossible to look directly at it, otherwise the eyes would feel stinging and tears would flow.
"Don't stare at it directly, squint your eyes, and use your peripheral vision to see, otherwise you will go blind." Luo Chong reminded them.
Several people hurriedly continued to observe according to Luo Chong's method, and saw that the leader aimed the light spot at the firewood on the ground. At first, it seemed that nothing happened, but within a minute, the firewood painted black began to emit gray smoke.
"It's on fire, it's on fire, there is smoke, there is smoke, the sky fire is coming down, the leader has brought the sky fire down."
An apprentice ignored the pain in his eyes and saw smoke coming out of the place where the light spot was shining. He immediately stood up and shouted. This shout attracted the attention of people nearby, and people who had nothing to do began to gather here, including Chief She who was supervising the construction site not far away, and the two old men, Rat Witch and Elder Han.
"It's really on fire, it's really on fire, you see the smoke is getting bigger and bigger, now put some wood shavings, it will definitely catch fire when you blow it." Big Mouth also began to summarize.
"What are you doing with the leader?" The elder came over and watched the two people shouting with tears.
"Oh, the leader made us a tool called a magnifying glass, which can draw down the sky fire, can directly light wood, and can make things look bigger and clearer. It's amazing. Elders, you can also take a look?!" Big Mouth explained.
"Oh? There is such a tool, what does it hold?" Rat Witch also asked.
"Magnifying glass!"
As more people joined in, the next thing was even more amazing. Several old men and a group of teenagers squatted under the scorching sun, lighting wood with magnifying glasses and roasting ants. The joyful screams came one after another, and they didn't feel hot, which made Luo Chong feel ashamed.
Look, look, this is my manager, just like a group of kindergarten children.
"Alright, alright, just watch for a while, the sky fire hurts your eyes, and you will all be blinded in a while, and you won't be able to see anything at that time." Seeing that they were having fun endlessly, Luo Chong began to urge them with harsh words.
There is no other way. This thing was not made for fun, but Luo Chong intended to use it to carve the wax mold for the steel stamp for coin casting. Without this magnifying glass, how can he carve the tiny patterns on the coins? This is a serious micro-carving tool.
