[Avatar: TLA] Was Sozin's Comet metallic, and if so, would a firebender wielding a sword forged from a comet fragment experience any of the comets firebending enhancing effects?

Sozin's Comet is a spiritual manifestation, not a physical object. It represents a massive release of spiritual energy associated with the energy channeled by firebenders, visible in the physical realm due to it's utterly preposterous magnitude. The end result is that firebenders are massively empowered during the event. 

The reason for Sozin's Comet's existence is that fire is greatly underrepresented on the surface of the earth. "Fire" spiritual energy builds up due to its inability to be passively released in things like the tides, winds, or growth of plants. Volcanic activity is not uncommon near the comet's "transit", another manifestation of the spirit world's massive overflow of fire energy. Finally, the energy overcomes the barrier between the physical and spiritual, and a comet is formed and released, creating the phenomenon known as "Sozin's Comet"

EDIT:
All these things being said, it still seems like it could be possible to create a Comet Sword by dunking it into the flame vortex. Dangerous? Yes. Probably not work the risk? Certainly. But would it be AWESOME?
