Copper Etching With Ferric Chloride - a Beautiful Process


Introduction: Copper Etching With Ferric Chloride - a Beautiful Process

My friends wanted to try out their hacked camera and vintage lenses, so I took them to the boatyard where I grew up, and showed them some of my jewellery making techniques.

I use the chemicals commonly used to make circuit boards at home, but draw designs free-hand to create textured metal to use in my jewellery.

Set to a dreamlike song by Roger Paul Mason from Brooklyn based band Jets and Snakes, the result is a mini-documentary/music video showing the creation of an etched copper button.
(For the Camera enthusiasts:

The video was shot using a hacked Panasonic Lumix GH2 - the sleeper hit of the indie camera world - an ultrabright vintage manual f1.4 50mm Pentax-M lens and Panasonic's superbright micro four thirds wide lens 20mm f1.7 lens.
The camera hack (by Russian hacker Vitaliy Kiselev) unlocks higher bitrate settings in the camera)

    SO beautiful !!! Thanks a lot!!

    A question about the marker: is it a regular marker? can simple ink resist the acid? Do you think it might resist to electrolitic etching too? thanks...

    Hey there! I borrowed this particular marker pen from a friend, so I'm not sure what exactly it was, but I usually use a Staedler Lumocolor. I'd recommend getting a bit of copper and doing a test - writing 1, 2, 3 etc. and keeping a key, to see which ones hold up OK.

    If it works for one, it'll work for another - you just need something insulating and waterproof. I have successfully electro-etched with wax, nail polish and marker pen.
