On this jet lighter of mine, theres this glob of metal or a wire, when the lighter heats up the metal glob glows orage and the flame turns green. http://darkfire.myftp.org/pics/4th/1.JPG
Theres a pic of the flame if i have my comp turned on, wtf is this metal?

The green colour could possibly show that there is barium in that wire, either as in the metal form or some of its salts. Don't know though,
I've often seen such lighters.

Possibly SrS or likewise compounds which glow when heated.

I presume I am missing something that rules out copper as the reason for the green colour.

I second you, unionised. It looks to me like copper: at higher temperatures, copper creates blue flames, but at lower temperatures it burns with a
green flame. Take a look at your picture again--the bottom part of the flame is bluish, where it would naturally be hotter, and as you approach the
end of it it turns green, where it cools down a bit.
Heating element alloys

If the lighter is one where a hot wire ignites the butane fumes then it might be a resistance alloy. Constatan or something simular. Copper is a
good conductor but when alloyed with much nickel, its resistance goes up. Other such alloys are based on nickel, chromium, and iron.
Oops!
Lighters dont usually have batteries(what electricity). My bad. But it
could be piezoelectric

I think it might be Nichrome.
