Chapter 119 Gretel’s Chemical Experiment Diary
On the morning of August 5th, the first experiment was conducted.
Replicating Lavoisier's "Twenty Days Experiment", the mercury in the retort is heated to produce mercury oxide.
Weigh 100 grams of mercury, add it to the retort (I'm really grateful that the mage tower actually uses metric units, it's probably the legacy of the predecessors who traveled through the big guys), and heat it with a stove.
One hour, no change.
Two hours, no change.
Three hours, no change.
It is suspected that the heating temperature is not high enough for the mercury to react with oxygen.
Move the retort closer to the stove.
The retort exploded...
On the afternoon of August 5th, the second experiment was conducted.
Red powder appears on the surface of mercury, which is suspected to be mercury oxide.
The retort exploded again...
Improper temperature control. Let me think about what method to use. A mercury thermometer will definitely not work.
On the morning of August 6th.
Bimetallic thermometer! success!
The mage tower is really awesome. There is actually platinum in the tower... The temperature sensing element made of platinum sheets and copper sheets is the best!
On the afternoon of August 6th.
Continue with the mercury oxide experiment. It's really easy to use a bimetal thermometer to mark the temperature...you no longer have to worry about the retort exploding.
On the morning of August 7th.
When adding charcoal, my hand slipped and the stove went out... Fortunately, the fire was rekindled in time. I really want to have a furnace boy.
On the afternoon of August 7th.
Keep burning.
On the morning of August 8th.
Keep burning.
On the afternoon of August 8th.
Keep burning. Come on, Lavoisier did it for 12 days, but after finding no change, he waited for 8 days.
On the morning of August 9th.
Wizard Elliot's cauldron exploded, shattering the retort...
"Gretel, I'm sorry..." Elliot came over to apologize: "What are you doing?"
Grete was busy cleaning up the mercury all over the floor and had no time to talk to him. Master Elliot carefully walked around him, and when he poked his head, he saw smooth handwriting on the manuscript paper on his desk:
1. Prove the existence of O
2. Prove that O + combustible + temperature = combustion
3. Introduce O into spell materials
"What's this……?"
Master Elliot only glanced at it and found that he couldn't understand half of it, so he immediately walked away. Gretel called him from behind, and he hurriedly walked without looking back.
Experimental ideas and spell design are the secrets and wealth of every mage, and they will never be revealed to others easily! What's more, he saw the words "spell materials"...
New spell materials, new magic, that is the core of the mage's power. If you look at it rashly, it’s not much different from grabbing it tomorrow!
Gretel's disastrous experiment begins again.
This time, he was thoughtful and moved the experimental equipment to the small room next door so as not to be disturbed. Lucky for him, the experiment was carried out smoothly without any glitches or slippage or anything.
Until late August, late one night, Gretel's cheers finally sounded in the Mage Tower:
"I did it! I proved-"
The air in this world indeed contains 20% oxygen! The combustion of combustibles indeed relies on oxygen! What phlogiston, what essence of fire element, go to hell!
"Gretel!" A window on the third floor of the mage tower slammed open. Master Karan put his head around and roared:
"Why are you howling in the middle of the night? You interrupted me just as I was about to meditate!"
Ah...oh, meditation. Grete apologized loudly, rushed back to the third floor, and got into his room. Enter meditation, explore your spiritual power, and feel the world around you:
Among the four elements, earth and water seem to have remained unchanged. Fire and Wind have undergone tremendous changes:
The light and elegant power is divided into dots, one part is stable and silent, and the other part is lively and jumping;
And the active and jumping part is slightly separated from the former, sometimes confused, sometimes flying to the area belonging to the fire, stirring up little bits of flames.
The essence of combustion is that combustibles combine with oxygen to emit light and heat.
Grete felt it carefully. My mental strength doesn't seem to have increased significantly compared to yesterday. He stretched out his hand again and flicked the candlestick in front of him, and a bright flame came out of his hand and landed on the candle wick.
The release speed is a little faster than before, and the power of the spell is also higher...but not enough, not enough...
Gretel spread out the manuscript paper and wrote and drew under the candlelight. According to Master Herman's lecture, every fire magic has two basic configurations: one is used to gather "phlogiston", and the other is used to filter "good air" that can attract phlogiston——
According to phlogiston theory, when a substance is heated, phlogiston cannot be decomposed automatically, and air must be added to absorb it. And "good air" has the property of absorbing phlogiston and can achieve combustion...
Then, the configuration used to gather "phlogiston" points to combustibles under the guidance of mental power; the configuration used to screen "good air" points to the oxygen specially carried as a casting material——
What will happen if we do this?
Grete heard her heart pounding. He rushed out of his room, ran to the alchemy room on the fourth floor, and once again set up the alchemy device for heating mercury oxide and producing oxygen. Once the oxygen in the test tube was collected, he took the test tube and quietly went down to the mage tower.
"Grete, where are you going?"
Suddenly someone spoke in the dark night. Gretel paused and turned his head slowly:
"Elliot? Sorry, did I just wake you up?"
"It's okay, I wasn't asleep to begin with. Hey, it's midnight. Where are you going? You didn't even light a lamp?"
As he spoke, he snapped his fingers, and four balls of light floated silently from front to back, left and right. Gretel followed him down and answered in a low voice:
"I have improved the Burning Hand and want to give it a try..."
"Burning Hands? You learn so quickly!" Elliot praised. He and Grete walked into the dark night together and came to a square behind the mage tower. This is a place used by mages to practice magic. Elliot concentrated slightly and raised his hand forward——
A red cone of flame spurted forward. Five meters away, a human-shaped wooden target was caught in the flames and immediately started to beep and burn.
Elliot put out the flames with a gentle wave of his hand. He turned to Gretel, his eyes bright and full of curiosity:
"you try!"
"I may be a little slow..." Grete replied in a low voice. He held his breath and concentrated, breathed evenly, and tried his best to get himself into a spell-casting state:
meditation!
Chant the mantra!
Use mental power to outline the spell model!
Explode your mental power and let the spell model resonate with the surroundings. Note that the configuration that filters the air must be pointed at the oxygen in the test tube!
Reach out, push forward——
boom!
Flames so blazing that they turned white spewed out from Gretel's palm and exploded forward.
Within ten meters, blazing white flames swept everything in a 60-degree fan-shaped area in front of them. Wherever the flames passed, the human-shaped wooden target was immediately burned to pieces and stood on an iron pile on the ground, bursting out with bright and dazzling lightning-like sparks.
Beside him, Master Elliot slowly opened his mouth.
"This...is this the Burning Hand? The distance is twice as far as mine, the flame, the flame is more than twice as strong!!! Gretel, are you really just a level 1 mage?!"
I revised the new chapter for the sixth time... (dead eyes)
