Creepy !? A black flame is on fire!
"Black flame" that looks spooky.
You will be surprised when you see it for the first time.
You may think that it is a real version of the black flame "Amaterasu" from the anime, NARUTO Itachi.
Its identity is light absorbed by atoms.
Each element has its own characteristic of absorbing light.
In the world of astronomy, in order to know what components a distant star is made of, it is a clue which light is absorbed.
Even in the world of material development, in order to know what elements are contained and how much they are contained, light of a unique wavelength absorbed by each element is used.
The “black flame” created by the characteristics of the element and the analytical method that makes use of it.
Please have a look.
