I just happened upon a product called Accoya. Seems to be (basically) a
way of preserving timber by treating it with acetic anhydride. (Yes -
noticed on the Grand Designs Live site.)

Must say, the claims are quite impressive. E.g. potential 50+ year life
as a window frame. Set me thinking, would it be possible to do anything
like this myself? I doubt I'd want to be dealing with acetic anhydride
(and re-drying it after use might not be easy) - so any ideas? I guess
blagging some non-brewed condiment from the chippy and soaking some wood
in that isn't likely to be sufficient.

Hypothyroidism is a seriously debilitating condition with an insidious
onset.
Although common it frequently goes undiagnosed.

Acetic Anhydride is DANGEROUS STUFF!
I have encountered it in a process plant environment and its behaviour
in the presence of moisture could be explosive to say the least!

Perhaps I wasn't strong enough in my comment? "I doubt I'd want to be
dealing with acetic anhydride" should perhaps be "maybe it's this side
of hydrofluoric aicd, but I DON'T want to deal with acetic anhydride
(even if I could get hold of it)".

Anyway - point well taken.
