Still working on the non-toxic oil prints. This is an oilprint using AFC instead of bichromate. I'm having mixed luck, but having fun trying to make it work.

It was made from a pinhole paper negative. I've never printed or scanned this negative before, I think it is from February 2015 "red rooster" coffee can pinhole camera.

Printed / inked 17 January 2016

i like how this turned out. what is AFC? i love seeing your exploration of alternative processes.

Thanks! It's ammonium ferric citrate, also sometimes called ferric ammonium citrate. Pretty non-toxic for a reactive chemical, it's also taken as an iron supplement. The gelatin is mixed with AFC and coated on the paper, dried, then exposed in the sun or under UV lamps, then the paper is dipped in weak hydrogen peroxide which causes the gelatin to harden where it was exposed to light. After that it is washed and then inked like a bromoil print. It's very simple, but not very easy!

There are still a few problems to be worked out, but it's getting closer and closer. If I get to the point where it is reliable I will write instructions over at APUG.

it sounds cool. when you get the write up done(or if) i hope you'll post a link - very curious about it all. is AFC the same chemical used in cyanotypes? oh wait, i think that's ferric cyanide.

Be happy to post a link. And yes, AFC is the same chemical used in cyanotypes, along with potassium ferricyanide. Cheers!
