It appears that a little thread maintenance is needed now.
The intent was to have some fun with incandescently lit photos.
The sunlit photos aren't really part of the intent but they are nice to look at so I didn't say anything. However, the Sun is incandescent.
Here are some things that should be addressed before this turns into a not-so-fun thread about scientific definition.
Fire does not require oxygen. Fire is the consumption of a substance due to heat (yes I know heat is being technically misused here but my time is limited) and other energetic forces (pressure, chemicals to name a few).
Body:
A body is a substance and can be a liquid, a gas or a solid. When most any BODY begins to glow due to energy input and or energy sustained conditions it is said to have become incandescent.
Plasma is a fairly new concept used to describe a fourth state of a substance which, though interesting in its dynamic structure, is basically a gas.
Most any type of BODY whether it be be a liquid, a gas or a solid can become incandescent. A lit candle has three (at least) forms of incandescence. The glowing bits of solid trash and ash moving about in the flame, the glowing wick and the glowing gas produced by the wax melting are all three incandescent.
I'm going to suggest that to help me keep this a fun thread please, everyone, continue to contribute. I'm also going to strongly suggest that if a scientific discussion about what is or is not incandescent is a member's desire please start a separate thread about that.
To say that a candle is not incandescent is just...well it belongs in another discussion.
