Self lighting candles

[Steven Polanski]

I need a little help on this one since my FX experience hasn't taken me to this effect so far.

 

How was the self lighting candle scene done in the movie 'The Craft'.

 

I think I can do this electroniclly but that scene looks chemical to me.

 

If you look closely there are what look to be two flames on each candle from the moment of ignition then they come togehter as one.

 

This needs to be real stuff, not in post because I want to shoot this in close up.
