Hi
Hmm thats strange. After etching nothing happend? Thats impossible. Hmm.

After cutting and polishing I heat every slice, clean in alcohol and put to
special protective varnish.
Its named Paraloid and its used to conservation of discovered ancient
artifacts made also from iron.

Unfortunatelly about month or two Dronino start rusting. Inclusions from
slices (mostly located closer to edges of specimens) start "growing". I was
verry desperated and send them again for polishing and then try to clean and
conserve them again. but this time vithout any varnish. Ofcourse nothing
happend, dronino rusting again. Then, becouse I was verry desperate and
angry
about myself why I buy this 5kg s*** who still cost some $$$ and my cutting
proces, where cut loses are 0.12mm is also not cheap as normall saw cutting,
I put all slices to table, one slice to another, and from time to time
puting on them new layer of Balistol oil. They stay untouched for about 3
months. I have no hope that I sell any of this slices in future. What is
strange, half of this 5kg specimen still stay near my window from january
and there is only a little rust on it, mostly on "crust"side, not on 4
cutted sides. Realy this is strange. This was not protected by oil or
something else. Just a miracle.

And at last, few weeks ago I again take a look on my slices. What I discower
it was that beetween slices is still rust, but this is old rust bathed in
the oil. No new rust. I cleaned few slices from oil and rust and they still
have this nice silver color like in time when I receive them from polishing
without. No visible new rust, everything looks good. And becouse I have few
other meteorites to etching I try to etch one of smallest slice and
WOWwwwwwww this what I see was verry nice.

Pattern is strange. Only idea I just have then was, that this looks strange
like Taza. Ofcourse this is not the same, but this looks the same strange
like Taza pattern, I not know any other similat pattern like from Dronino.
There is good contrast on slices, but pattern it alvays visible only from
one side. If You turn it on 180* pattern will be visible only a little. So
thats why on one photo pattern is super and on another not verry good
visible.

Its maybe not verry good advertise about my Dronino, I talked here a little
too much about rust hehehe but maybe this will help someone to stabilize
Dronino Slices.

I but my Dronino in november '03 before Finmet start writting on his
auctions that at last they find how to stabilize dronino and they will not
rust also if You put slices to water, hot/salt water etc, etc, so I do not
know if this is truth or not. But what I can say about my specimens is that
they really stop rusting right now. They still stay in the same place on my
table (i dont want change this "lucky localisation") bathed in Balostol
waiting for high bidders from eBay. I watch them carefully if nothing will
happend, but fortunatelly they stay in verry good condition.

This is my loooooong 2 cents to Dronino case. Someone realy should watch
Dronino again and test if this is at last ataxite or not.
