Hello Ryan (and all):

I use activated clay as well as silica gel (not the blue). I believe you
can get your r.h. to go a bit lower with the clay, by just a few %. The
disadvantage is that clay absorbs moisture whereas with silica it is
adsorption. After the clay becomes saturated it can release some of its
moisture content back into the air around it depending on its temperature,
whereas silica will continue to retain it, so one must keep a watch on the
conditions in the container. The activated clay is a bit cheaper than
silica packets.

I don't get near calcium chloride as chlorine seems to be a forbidden
entity where meteorites are concerned.

We offer (plug coming,...be aware!) silica gel packets on our website at
www.meteorite1.com and humidity indicator cards. I also can provide the
activated clay packets at a slightly lower cost, although I am not currently
listing it. I can provide this information on request. (I have it in stock
as I use it in our cases for the museum collection and it works well for
us.)

Would any of you prefer using one of these types over silica gel? Any
recommendations anyone?
