For Chrismtas I was a given a wonderful gas lighter, that produced a pink flame by heating small metal pads (when the pads are cold, the flame is blue, once they are red hot, the flame is colored).

Sadly, two weeks after the flame is now true orange, so i'm currently trying to give it back its special color, or another funny one (green or purple may be fun, a brighter flame too).

Before the question, I made some noobish assumptions :

  • The flame color is due to the reaction of the hot metal pad (via electron excitation), not to the combustion of some chem on these pads.
  • The metal pads were coated with a specific material emitting pink, but the coating was scratched, corroded or burnt, so the flame now only react with the inner metal of these pads, emitting orange flame.
  • I only have to deposit the correct metal on these pads via electrolysis to get back the good color.
  • As the previous coating disappeared, I probably smoked some of it.

Even as a smoker, I'm still worried about health issue : do you think I can find a suitable metal for this application, or is this just plain stupidity to light cigarettes with this "portative flame test device" ?

    $\begingroup$ Assumption 1 is not exactly correct: compounds such as lithium salts may not "burn", but they ionize in the flame and are used up. Look up "flame color test" for ideas, and avoid poisonous ones such as barium. It seems like an interesting tool, and smoking tobacco will reduce the cost of your country's retirement plan nytimes.com/2001/07/18/news/… $\endgroup$ – DrMoishe Pippik Jan 9 at 3:38
