Short title	Source heating a target while vapour, oxygen and heat losses shape ignition.
Image title	A small flame acts as ignition source next to a block of target fuel. The source heats the target (wavy arrow), the target releases fuel vapour that mixes with incoming air above it, and ignition occurs where the source meets this fuel vapour and air mixture. Dashed grey arrows show heat losses from the mixture and the target to the surroundings.
