Definitely caution when playing around with corrosives is of the first
order...that said,
sure, ethanol is a racing car engine fuel and under the right
conditions can combust; But people drink it even straight...
Many things we do have risks associated with them some very serious
Besides water, I'm suspecting Nitric + acetone (Nitkeytone ?) and any
number of other solvents would work
OK, don'rt bother with this one! I just did; It actually etches, but
leaves a yucky finish. The fumes are no worse than other nitals,
though I wouldn't want to breath much of them until

I believe there was an article by Hartman a few years back about the use of
ferric chloride. The conclusion was that it gave a better etch??? I think
it was in Meteorite-Times.

Every photo of Tissint I've seen in photos it is unique in so many ways.
Freshness, flowlines, orientations, depply sculpted backsides... Other
than its freshness is there a particular reason for its unique look?
This is just one of many and they are all spectacular in so many ways.
Hi Jim,
My respects to all the ferric chloride lovers out there and especially
Ron Hartman, bless him. A blanket statement of a better etch is
pretty meaningless. I recall asking Arcady who had all the Seymchan
several years back why all of his specimens were etched so deeply that

Holy crap! That really sucks!!! (as I state the obvious) If you have pics of
those taken, please post them asap, so we can all help in locating them ASAP.
One thing about meteorites, is that they are like snow-flakes, where no two are
the same, and can be easilly identified.

Hi,
Couple of thoughts.
Mark's Law:
If you're standing in the exact same spot as someone else when a mixture of
nitric acid and ethanol explodes, the sensitivities of the two individuals
to harm are always the same. :-)
Both nickel chloride and nickel nitrate are soluble nickel compounds,
Hi Mark,
Would appreciate a reference for the nickel chloride being 15 times
more carcinogenic than soluble nickel nitrate.
That's not what I wrote although it could be true I have no such
reference to support the above.
What I did write was:
Only Nickel chloride (a result of ferric
Hi Doug,

Hi Mark and Doug and all!
Another good topic...that goes along with etching meteorites is the
polishing compounds used prior to etching. For example, a 1 micron
polishing compound or mixture has it's own set of safety issues. The
concern is absorption through the skin, etc! Most probably do

Sure Mark, now that you dropped the respectful line completely, I don't

One more thing to the discussion which IMO is constructive and useful
to anyone considering etching with some practical numbers but by no
