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 stable, and
some are not. Perhaps I will naively ask, "Is it all about chlorides?"

Sincerely,

Stephen McMann

They are not stable. The older pieces was slag in a few weeks or months,
the new "stable" ones in 8 - 10 months. I have just one very thin piece not
distroyed, just because it has a quite heavy lacquer. Fastest ruster I have
ever seen ;-

best,

pekka
