[meteorite-list] q on storing micromounts

[drtanuki]

Dear concerned,
    I would not use "sponge" as it usually contains
vinyl chlorides which will oxidize iron with water
vapor present.  Cotton in my humid climate...even
paper...is a no no because it tends to absorb water in
my climate in Tokyo.  Good luck!  Dirk Ross.Tokyo

Vapor-proof boxes with silicon desiccant are most
likely required, but highly depends on the meteorite 
case by case.
