Smouldering - char cloth
low-temperature, flameless form of combustion, sustained by the heat evolved when oxygen directly attacks the surface
Smouldering fuels are generally porous, permeable to flow and formed by aggregates (particulates, grains, fibres or of cellular structure). These aggregates facilitate the surface reaction with oxygen by allowing gas flow through the fuel and providing a large surface area per unit volume. They also act as thermal insulation, reducing heat losses.

Mirror size : 8cm diameterSun : 300 W/m2 ( November Sweden )
The effect hitting the mirror : 0.04*0.04*π*300 = 1.51 W
Let's say that 70% of the incoming radiation i reflected to the focus dot 0.4 cm diameter, thus resulting in a 0.7*1.51 = 1.056 W at an area of 0.004*0.004*π=0,00005027 m2
Emissivity = 0.9 "wood" ( chaga - tinder fungus )

T=(1.51/(0,00005027*5.6703E-8*0.9))^0.25 - 273 => 600 °C
