Thank you all !!

I'll try to find Nital 2%,
don't seems easy to find.

I work in an highschool; I will ask my colleague teaching physical if they have nitric acid in the laboratory and mix it with ethanol...( sure glasses, gloves and laboratory fume hood).
We'll see ...

Hello,

I found concentrated chlorydric acid ( 20%) but no nitric acid,
I read it attacks strongly iron,
Do you think it can be used too ? ( 1-2 % ?)
