[Terrapreta] Char made made under pressurized conditions?

[Greg and April]

Hmmmm....

I will not argue with you there, as it's quite possable that the process of
loading into the super sacks, could have been enough to "fan the flames" -

OTOH, I keep hearing about those that empty kilns, that are so hot, that
they do not have to relight them as the heat from the kiln does that with
the new load of wood - yet they don't have issues with the char relighting.
Perhaps they quench their char, once it is unloaded from the kiln.
