How can a candle make oxygen? : askscience

But these “candles” contain their own oxygen in the form of sodium or lithium chlorate. When heated, it breaks down into a salt and oxygen gas. Some of the oxygen is used to continue the burn, but there’s far more than can be used by the amount of fuel in the candle, so the rest is released as a byproduct.

Candlestick Rocket Ship | Science Mission Directorate - NASA

One reason for the benign nature of candle wax is that the oxidizer needed for it to burn is separate from the wax itself: air in the case of candles, and pure oxygen for rockets. (Chemically speaking, combustion is the rapid "oxidation" of the fuel, usually by combining with the oxygen gas in the air.
