Hi Paul, thanks for pointing our attention to this paper.
What about the kind of glass for the vials you suggested? Is there any 
specific type that may release acidic gas and should be avoided? I have 
seen specimens stored in glass vials in old collections that were 
severely affected by Byne's disease, but I cannot tell whether the main 
culprit was the glass, the stopper or the paper.
Cheers, Paolo
