[meteorite-list] List of known Rusters?

[al mitt]

Hi Ed and all,

This has been discussed before and I believe the consensus was that WD40 can 
have moisture in it that will promote rust. It depends on the batch but 
there is varying degrees of water contained in this lubricant. It might not 
be so good for Nantans but more stable irons like Gibeon would probably be 
fine.

A good grade gun oil like Birchwood brand, Barricade seems to do better in 
my experience but smells a bit. Bottom line here, Nantans are often unstable 
and may have been weathered to the point you'll never be very successful at 
drying them out. These are notorious rusters.

I like very much your idea of a list of meteorites that are problems 
specimens. Perhaps we could develop a rating system (1 to 10), (stable, 
mostly stable, partly stable, unstable, extremely unstable) or something 
similar and a listing of specimens. Even the metal in ordinary chondrites 
can rust. An example is Ghubara, Omen. About half of the pallasites out 
there are problem specimens, and a number of irons are.

Best!
