[meteorite-list] Nitol Etching Formula

For instance, you can readily buy 70% and 90% alcohol at any store
or the ol is the read end of alcohol maybe because it's at the end of Nitol

Actually, the ol is from the last two letters of alcohol, not the first, and
I believe comes from the common short hand abbreviation used for alcohol in
various scientific and medical disciplines. I've never seen nital used, in
college or since, though as long as everyone knows what we're
Been reading some posts regarding etching I believe the term from the
science of metallography is Nital...NOT Nitol. The al is the first part of
alcohol, just as the Nit is the first part of Nitric. This incorrect
terminology has been perpetuated for some time now.

Hi Desmond and list,
Yes, diluted (5% or less) ferric tri-cloride ( Fe Cl 3 ) works
well. I used it for many years for some art work (etching cupper plates)
and I also used it to etch iron meteorites - it's not a very harmfull
acid. In Switzerland you can get it in every drugstore.

hi, all,
I got some suspected iron meteorites. I want to
try to etch them.
Does anyone know other easy methods to etch instead
of using nitric acid? I find it difficult to buy nitric acid and quite
danger to handle myself.
Could anyone tell me other methods? Any existing
spying chemicals
Hi Desmond and list
Some time back it was posted that ferric cloride (a pc
board etchant avail at radio shack and electronics
suppliers) works well.
