  Something that would help this flame a lot is a color map entry for
the density statement. Without it you really have little to work with.
Take a look at the media statement I posted for Scott to use with his
Drunken Dragon image. It has some modifiers that ae close to what you
used but adds some color and depth to the flames. Stick with your own
container as the one I use for my candle post was pitiful at best.
Also back off on the emission values I used. I was tring to see how
far I could push it before the high emmision washed out the flame
with white light yet still add some of it's own light to the scene.

  I do like the coloration of your wax and the translucency you have
achieved supports my opinion that for this kind of model anyhow a
new translucence function in Pov is not needed. As Marcus say's though
there are other situations where it might come in handy so I wouldn't
argue against the Pov team adding it if they choose to do so.

  The one thing it seems to lack is that little pool of clear liquid
wax around the base of the wick. A minor point and easy to add I would
think.
