Hi Graham and List!

I had some Gujba (some slices and one end cut) and also one fragment,
all from the same source! One of the slices and the end cut I took with
me to different markets (mostly under free sky including some rainy
days) a long time and had never rust problems with them....

One slice I had never outside my room and it has started to rust!!!

Think that the material is very different and that some pieces are more
stable than others!

Do know nothing about the best action to preserve the material in this
case!

Best Wishes

Ingo/Germany

Betreff: [meteorite-list] Rusting gujba!

Hi all,

Has anyone else on the list had problems with gujba rusting? I have a
good slice which is just starting to show some signs of rust in a couple

of places. It is kept in a reasonably dry environment in a membrane box.

If anyone has any suggestions of how to stop it deteriorating. I would
be most grateful for advice. Because of the nature of Gujba I am loathed

to use any oils that would change the appearance of the non metallic
areas or use some of the other methods that I have found help with other

nickel iron meteorites.
