  The glass is put on the plate *after* the candle has been lit, so the air
around the candle is already hot.

  An interesting experiment would be to put the glass first and *then* light
the candle to see what happens. (Of course you have to devise a way to do
that. A magnifying glass and sunrays might be enough.)
