One warning about desiccants... never let it touch the meteorite! It
absorbs the water and if it touches the meteorite then the water is also
touching the meteorite.

Hello Gracie and List.
I live in southern California and I had, up until recently, been
thinking I should be fairly immune to humidity and rust problems.
Wrong! I've got a few irons starting to show a little rust and some
pallasites (Brenham mainly) with more severe problems.
I think desicant would go a long way in helping you. Just make sure
you get a color coded, rechargeable type, so you can see when it's
moist and dry it in the oven.
I would definitely recommend Bill Mason's kit, which you linked us to.
I recently purchased one from Bill, at the Tucson show. I've yet to
break it out and put it to use, but was impressed with the demo that I
got from Bill.
I'm a relative novice with this topic though, so wait and see what
others have to say. Best wishes.

Subject: [meteorite-list] Meteorites and Humidity: Some Questions . . .
Hello Met List!
Quick background info:
About six or eight months ago, I began a meteorite collection. (I am so
completely hooked.) I store them primarily in Riker boxes and some in
the
jewel cases they arrived in. I live in north central Florida and except
for my air conditioned home, I don't have the meteorites in any other
climate controlled container or cabinet. I'm noticing a few of the irons
(Miles especially) and one or two of the stony irons to appear a little
rustier than when they arrived.
I've read the good information here
(http://www.meteoritemarket.com/preserv.htm), but still have some
questions.
Given my location, is it unreasonable for me to expect that simply
purchasing (and consistently replacing) desiccant for each Riker box and
jewel box will stave off rust? I love having my meteorites on display
and
the notion of squirreling them away in airtight tupperware makes me sad.
That being said, I would prefer to protect them than have them ruined by
humidity.
There are a number of places I can purchase desiccant online. Is there a
preferred or recommended location?
Finally, is a kit like this worth my time and money?

Thanks so much for your help!
Gracie
