The question is this: What are the flames made of? Yes, I know that they are the gasses from burning wood, or from gas or oil, or anything else that burns. These gasses mix with oxygen and burn. That is all understood. What is not understood is what is the actual flame that we see? They are usually yellow and orange and semi transparent. Or they are blue from natural or LP gas and also semi transparent. They emit light and heat. But what is the flame and why do we see it?
Maybe I'm getting too deep in my thinking about it. After all, its called FIRE, and maybe there is no further explanation. But the flames are real. They can be seen. Yet, what are they?
We know how the light from a lightbulb is created and florescent lights are different than filament types, because they produce ultraviolet light (which we can not see), but that makes the florescent particles glow. While we can explain how light is created from light bulbs, I've never gotten a real explanation about how fire becomes visible. Does it also produce ultraviolet? Is there some florescent type material in the gasses that make it glow?
