Hi Bernd and all,
Nitric acid is bad stuff. It will stain your skin and should only be used
with protective gloves and googles. It is a cancer causing material and
extream caution should be used at all times with this acid.It also tends
to explode when mixed with different items. Other than that, it is great
for etching meteorites.
I have never any problems with nitric acid. For me it work excelent instead
of other methods.

Hello Michael and List,
Although it has been said many times before, we should put potential
newbies,
who would like to etch an iron meteorite with nitol, on the alert:
Please, be
careful and do wear protective gloves and goggles, because, and let me
now
quote from our late R. Norton's Field Guide to Meteors and Meteorites, p.
255:
"When mixing ethanol/nitric acid solution great care should be taken to
see that
the nitric acid is always poured *into the alcohol beaker, never the
reverse!
This prevents splattering of the acid as it is applied to the working
solution.
(Working with concentrated nitric acid is dangerous and requires handling
with extreme care.)*"
Wishing you a good night
from late night Germany,
Bernd
