Whether the chemicals giving rise to the natural durability are the
cause or it is some other feature, sweet chestnut snaps, crackles and
pops so much it is not suitable for use on a domestic open fire. I
always took this to be because water was trapped in parenchymous
tissue and became pressurised. These micro explosions do mean that
charcoal made from sweet chestnut flakes badly. I have noticed that
drying sweet chestnut cases a lot of internal splitting even if the
initial source is sound, not shaken.

I cannot comment on this as I have no experience, perhaps a post to
the gasification list may produce an answer.

What cation problems would be specific to willow? Are you referring to
ash carry over causing alkali metals to adhere/react with hot surfaces
in the gasifier?
