[Cob] cob Humidity buffers--we always knew it

[Amanda Peck]

adobe bricks

bentonite clay mixed with perlite (crunched styrofoam peanuts might work as 
well)

end-grain wood

They're all pretty fair humidity buffers, according to this article by Tim 
Padfield, who works in the really obscure field of Conservation Physics. He 
also once took a cob workshop.
