Or storing it in oil after the alcohol/NaOH bath?
As I say before, I stored my etched droninos oiled with Balistol in open
air and they looks stable for some months. And I not used on them NaOH
solution yet. I etched them around may/june and maybe 2 weeks ago I sell my
last one.

I must have the weirdest environment ever to try to preserve meteorites
in... My 10 g piece of Chinga, which one of the other List members described
as practically natural stainless steel, has a nice little swathe of rust
across its face. I will need to clean and treat better than half of my
Dear Pekka and List,
Has anyone ever tried some of the tried and true iron stabilization
techniques on Dronino, such as a long bath in an alcohol and NaOH rich
solution to remove chlorides? On a related subject, I guess that I may not
really understand the chemistry behind why some meteorites are

Well, have tried everything except black magic and woodoo...;-
Dronino is a quite old one, accordindg Verdansky from before
12:th century. Main part of the pieces was found from the very
wet area, so I suppose, the chlorides are not the only problem...,
the meteorite is just too old and have spent
Nope, as far as I know. This mirror-polished fellow was
stored in the air-tight plastig-bag, and some 10 months it
was a real beauty. Then it started to rust very fast, or in
fact not only to rust, perhaps boiling is a good word for
the process...;-
The beauty today;
I thought it wasn't a good idea to store meteorites in plastic bags. I
would think storing it in a bell jar with the air evacuated would
stabilize it.
Just a thought

You may have right, but think Dronino have enough oxygen in it
to rust even in a full vacuum...;-
It looks to me, old Campos, Nantans and so on rust very different
way than Dronino, which destroys itself from inside out, that´s
way I used the word boiling. Perhaps this fellow is an ancient
I thought about that too ... what about storing it in alcohol?

Have any of you who are fighting with rust/decay problems with Dronino
tried storing with desiccant in an airtight container after treating with
the alcohol/NaOH bath?
I can remember Steve Shoner telling the list about using the alcohol/NaOH
solution bath. As best as I can remember, he was the
What about storing in a vacuum with a container of concentrated sulfuric
acid after the alcohol/NaOH bath?
