Burn first aid as told to me by an ambulance officer when Caleb was scalded:

Don't put ice on burns, it can make them worse as you can get a mild form of frostbite on the burn. Cold running water for 15 - 20mins then wrap the burn in gladwrap and then wrap a cold damp face washer over it.
The gladwrap prevents the movement of the air from creating more pain to the burnt skin and change cold wet facewashers as they warm up to body temperature.
A cream that contains silver nitrate will help it to heal super fast. Look for one called silversol or something similar.
sounds painful!
