[meteorite-list] List of known Rusters?

[mail at mhmeteorites.com]

Hi Anne
I am sure it was from Al's nearly perfect prep work and it may have been one of the early masses found in drier areas.

I have a super Nantan endcut and a pretty nice Brahin (both several years ago) and 2 year old Fukang slices with no rust. When I choose pieces I look for ANY evidence of chlorides on the surface and in cracks (use a hand lens).  Regardless if someone says "it has been stabilized.

Hello Jason, and all,
 
I certainly agree with you when it comes to Dronino and Nantan, I have 
heard them called "temporary meteorites" and that does fit quite well.
However I have right here a slice of Brenham about a foot across, it came 
from an old collection and it was cut/polished by Al Lang some 20 years ago, 
there is no varnish, nothing on it, and not a speck of rust. I know Colorado 
is relatively dry, but it was in a much more humid area before coming here.
Same thing with a large end-cut of Brahin, from that same old collection, 
again no varnish or other protection and again, no rust.
I wonder if the initial care it received right from the discovery does not 
make a much bigger difference than we usually think. For instance I have had 
slices of Fukang, some rusted quickly, some never did. Same thing with 
Chinga, Montdieu, Admire. And they were all kept here under the same condition.
The only thing ever used on them (and not all of them) is Bill Mason's 
spray.
Any other ideas?

Hello All,
I can't speak for its effectiveness, but Rig Universal Grease is still
available:

If this is what you're talking about, it doesn't look as though it's
being discontinued any time soon.
Also, stay away from Nantan, Dronino, Campo, and
Muonionalusta...unless they've been professionally treated.  Brahin is
also cursed, as are Brenham and Admire.  They can supposedly be
treated to prevent rusting - not having owned any of these meteorites
because of the horrors I've seen (well, we once had some Nantan, and
now have several), I again will not comment on the effectiveness of
these treatments; I've no idea if they work or not.  All I know is
that all of those meteorites are predisposed to self-destruction.
Regards,
Jason
