[meteorite-list] Protecting Irons (School Collection)

[Erik Fisler]

Hello all,
Personally I'm not a fan of irons but a friend who works at my Community College 

for my University Physics course is. For the school, he has built a collection 
of chondrites, pallasites and irons; Franconia, buck mnt., palo verde mine, 
bassikanu, campo de cielo, canyon diablo, holbrook etc... I added a few pieces 
to the school's collection as well because it is quite small. He has a problem 
with a few irons rusting a bit. Can someone offer me any solutions I can offer 
him? [Erik]
