Our experience:

You will not remove all the moisture that gets deep into fissures and at the
boundaries of the inclusions in an iron meteorite simply by any method if
the meteorite is treated at room temperatures. We heat the iron meteorite
in an oven to a high temperature in a protecting oil which expands the
cracks and allows a protecting oil to replace the moisture. The protecting
oil prevents discoloration and damage to the iron which would occur if
heated otherwise. It works perfectly. None of my iron meteorites rust.
The protecting oil is then swabbed over the surface and allowed to evaporate
for a few days, then the remainder is removed and the surface allowed to
fully dry, protecting the meteorite from absorbing additional external
moisture. Such an oil is ordinary ATF as used in modern automobile
transmissions. (And it is cheap!) The method was developed by my son, Jim,
and has been partially described in one of my previous articles in METEORITE
TIMES (November 2002) in which we described proper preparation of the
surface of an iron. The details using the AFT was not discussed there as it
is a bit tricky and I am not suggesting that anyone try this as I don't want
anyone to burn down their kitchens or blow their heads off, but with careful
experimentation someone experienced in lab techniques can achieve much
success. Heating carefully as described in the article should give good
results.

Other techniques have been described by various preparers and some of them
seem to be successful as well. But each iron is unique and no method works
exactly the same for any two.

ok, folks what it is? let's see the TOP 10 sweatiest,
crappiest, rustiest, hear-it-crackle- as it falls
apart in your hands 5 seconds after sawing, skyrox.
i'll start with: tsarev, brahin, campo. what have YOU
got?!

MT. DIEU... PEEEE-UUUUU !

Nearly impossible to cure.

Yes, Jim and Ron's method does work.
Regardless of what Steve Schoner said, I have a very nice full slice of
Montdieu Jim prepared some 3 or 4 years ago, and it is still in perfect condition.
It works!!
