It can be both as in case of magnessium it is exothermic but in case of alluminium it is endothermic.

Oxidation is basically the adding of oxygen or removal of hydrogen atoms in a chemical reaction, there is no heat involved in oxidation.
But processes such as evaporation, sublimation are endothermic
While processes such as burning (2C + O2 ---> 2CO2) are exothermic

needs more air in the mix. open the vent at the base.
A yellow/sooty flame indicates that not enough oxygen is being supplied to allow all of the gas to be burnt. Adding more air adds extra oxygen (from that extra air) which enables complete combustion (=burning) of the fuel (=gas) to take place.
A clear blue non-sooty flame indicates that complete combustion is taking place.
