Reacting with oxygen in the air, the vaporized wax then combusts into a flame, releasing:
- energy, in the form of light and heat
- trace soot and smoke
- carbon dioxide
- water particles
This process continues for as long as wax and oxygen are available. Though we recommend only burning candles for 3-4 hours at a time!
So the long and the short of the candle’s seeming disappearing act?
Candle wax is transformed by a combustion reaction involving the heat of the flame, plus the presence of oxygen and fuel. This reaction turns the solid wax into invisible carbon dioxide gas and water vapor.
