Jeff,

It's not a case of when is it 'stable' but, is it more stable than it
was!=20

Depending on how you attempted to stabilize it (whether it be coating in
Lacquer, oven drying or sealing in desiccated boxes)=20

All meteorites deteriorate to some degree, most are not homogenous so
when you add oxygen/chlorine from the air and water vapor they start to
change chemistry, the trick is to try and omit as many external
influences, as possible, with Brahin that normally entails omitting
water vapor (i.e. store it in a dry atmosphere! - And don't touch it
with bare fingers).

I would say providing you have taken the precautions above, you can
relax until the specimen looks like it needs attention!

Regards,
Mark F.

Subject: [meteorite-list] Brahin question

When can you be sure a Brahin is stable? When I first got interested in=20
meteorites 6 months ago, I bought some nice pieces of Brahin, impulse=20
purchase before I knew very much. I have several articles about rust
since=20
then, and I know what to look for, and I think I know what to do or who
to=20
call if they start rusting. But mainly, I want to know, is there a point

where I can more or less relax and assume they are stable?
