[meteorite-list] Brenham Instability Myth

[almitt]

Hi McCartney,

Your absolutely correct, there are plenty of Brenham specimens that are 
stable. I know that there have been some in museums for 70 plus years 
that don't appear to have any problems and were probably ones found in 
drier areas so they aren't as prone to rust. I am sure they are keeping 
it a more environmentally controlled setting compared to most 
collectors. A little attention to any meteorite is in order to keep it 
preserved.

Any iron (or for that matter) metal object that is exposed to 
weather/moisture will corrode as the Oxygen molecules attach themselves 
to the material. I've seen my share of rusty Brenhams and they can be a 
disaster. I've also seen Brenhams that are stable and only require a bit 
of care. I have a slice myself that doesn't cause me problems and I have 
had it over ten years.

Those complaining about them or who have had bad experiences with them 
haven't handled enough specimens to know that there are decent specimens 
around if you know where to find them. I look forward to your report on 
the Brenhams and perhaps we can all learn a bit.
