[Terrapreta] Earthen Kilns Conjecture

[Michael Bailes]

Australian Aboriginals encouraged the burning of large gums so that a hollow
was made though the centre of the gum.
Amazingly gums survive this traeatment and live on.
The hollows became great nesting places for native animals and therefore
convenient larders for fresh food for the aborigines.

I am not sure how this is relevant
But it would be interesting to set alight to a rainforest hardwood tree to
see if it formed ash or charcoal.
