Short title	Expanded char layer reduces heat flow to unburnt material while volatiles escape and char oxidises.
Image title	Cross-section: flames above a thick porous intumescent char layer on top of unburnt material. A thick red arrow shows heat flux from the flame reaching the char, and a thin red arrow below shows the reduced heat flux reaching the unburnt material. Dashed grey arrows show volatiles still passing up through the char into the flame. At the right end of the char surface, oxygen (blue arrow) reaches the char and an orange zone marks char oxidation.
