[meteorite-list] nital and etching

[Francesco Moser]

Hello dear friends!

I want to try to etching some iron meteorites and some mesosiderites, but I
never try this!

I have here nitric acid HNO3 at 65% and ethyl alcohol at 96% .... and now??

Could you give me some tips about the nital preparation procedure???
The best percentage? It's better, more safe, to put the HNO3 in the alcohol
or vice versa?

Every tip are welcomed! :)

Thanks a lot!!!

Francesco!
