Well after seeing all the candle posts I decided to make my own. This
was modeled after a candle in my home. The candle flame is composted of
a union of a sphere and a cone, then I duplicated the union and scaled
it down slightly. I still don't like the pointy look. Perhaps if someone
could give me a little help with media I don't use it much, actually
this is only about the third time I've used it. I have also pasted the
candle flame material here for anyone who wants to help with the flame.
This image was done quite quickly so forget about how empty it is it is
just a test image, I am only concerned with the flame. If you look
REALLY closely at the bottom of the flame you might notice a SMALL blue
area, This was created with a second bluish media, which needs to be
more prominent.

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.

THe Dragon isn't drunk, he's just moderately tipsy.

Thanks for the suggestion!

Actually I did add this. that's why the wax at the base of the candle is much
redder than the rest of the candle. I guess I need to turn the specular and
phong highlights up on it, and possibly its reflection values.

Thanks for the code!
