This week I bought a bottle of ferric chloride, because I am really curious to try etching copper and brass. My friend Alek from Infinity Stop (hope her wonderful shop will open soon again) showed interest and asked me to show her the results. I have a very busy day, but I got few pieces etched and here is everything I did in pictures.
Back side of the piece should be fully covered with pen (I used one for metal)
Taped in the box before I pour in the ferric chloride
And the result after hour and a half, I don't know why it took so long. The instructions I read stayed for 30 min.
