I've also wondered about this. I assume in the right conditions you can plot the stove in the snow to cool, but obviously there isn't always snow, plus I am sure that causes a good amount of metal fatigue over time...With a small (stainless steel?) stove and a morning fire, about how long does it take for the stove to cool enough that it can be packed?
I mean, I realize that it would depend upon how many coals are piled up in it but on a portage trip, is it best to skip the morning warm-up so you can get moving & use the stove in the evening for a warm-up or is the morning fire likely to be a minimal delay?
