Candle burning is  the combustion of paraffin solid, but the ignition device ignites the cotton core. The heat released will melt the paraffin solid,  then vaporize to generate paraffin vapor, which is combustible.

When the candle is ignited, the flame is smaller at first,  gradually becomes larger. The flame is divided into three layers (outer flame, inner flame  flame core). The core of the flame is mainly candle vapor,  the temperature is very low. The paraffin in the inner flame is  fully burned,  the temperature is hotter than the flame core. Due to some carbon particles, the outer flame is in full contact with the air,  the flame is very bright  fully burned,  the temperature is very high.
