Francesco:
Do you mean sodium nitrate (NaNO3)?
While we're on the topic, which solution of nitric acid works best for
making nitol? The purest I can find seems to be 67.2%. What would be the
ratio of alcohol added to make nitol?

Hello, I have a roughly cutted Muonionalusta slice to make beatiful.
I will grind, polishing and etching it ... and after for prevent rust and
stabilize it I'm planning to use the method alcohol + water + NaOH .
But I have few question:
Ethanol at 96% works fine?
I have to use distilled water or normal water?
For 100ml of solution I have to use 70ml of ethanol and 30ml of water, is
this proportion correct?
How many grams (or spoons) of NaOh I have to use?
How many days I have to leave the slice in the solution? 7-10 days? In this
period I have to change the solution or the first potion works fine for all
these days?
And after? What I have to do? I have to wash it with ethanol and after dry
up in oven, 80°C?
After could I also put some rust prevent varnish?
Any other tip are welcomed!!!
Thanks a lot!!!
Francesco!
