I have finished (at last !) to remove the varnish from my metal plate so as the white (well black for the moment) vine to show up.
As the next step was the etching, I put the plate in the acid bath immediately.
Unfortunately, it remained too long in the acid and the result, even if interesting, is not what I expected it to be.
We’ll see whether the next step will improve it or not 🙂
