In this activity a common wax candle is lit in order to study the zones of its yellow flame. The video demonstrates that there are three zones, the coolest dark inner zone in which there is no combustion, the warmer and intermediate luminous yellow zone with incomplete combustion of the wax and the hottest zone on the outside, which is barely visible and blue in colour. The outermost zone is hottest because complete combustion of wax occurs in it. A flame is the visible gaseous part of a fire. It is important to remember that there are parts of a flame that are not visible and still very hot.
