I could use some feedback. I frequently etch fine silver in ferric
nitrate, I’ve used PnP, ImageOn Ultra and paint pen. I get a
fabulously detailed etch, but the resists begins to brake down
before it can get deep enough for my use- one nice layer of enamel.
I have tried: giving the resists a day to sit, new acid vs slightly
used acid, heated vs non heated. Should I switch to Nitric acid? Any
help would be appreciated.
