Hello,

And many thanks to *everyone *who answered. I somewhat did not expect such
an active course of discussion.

At this point I need to say that I am not only collector (and did't wrote
this anywhere) - I am small dealer also. I cut and prepare irons and
pallasites by myself for 9 years, so I have some experience in this. You
can see my works on ebay for all time, please don't consider advertising.

As all who works with irons and pallasites, I have certain methods of
stabilization. Sometimes they works great, sometimes only for some time,
sometimes don't work at all. The reasons can be imperfection of my methods,
quality of specific initial pieces and rather humid climate where I live.
But the main factor (just my personal opinion) is meteorite itself. Are
there many of us who have seen stabilized for years Dronino or Admire? Even
Brenham or Muonionalusta? Short time - no problem, but for years?

Polished to mirror slice of Sericho without any protect (was left as a test
specifically) get rusty for 5 days. So the purpose of my question was to
understand is this my preparing methods so bad, piece, climate or Sericho
is itself so.

So thank you ALL again, for your advice especially. Happy Holidays and best
wishes from Vilnius,
Andrey
