I have a supply of completely unusable RC paper and thinking that I might be able to use to make cyanotypes. The idea is to completely fix out and wash the undeveloped paper, and then coat the paper with cyanotype chemistry. I think it would work, but I'm not quite sure about the gelatin and the RC base. Everything I've read says that a non-buffered or slightly acidic paper base is the preferred medium. I'm just looking right now to see if I can get this to work, and not looking to make a piece of art from it. Has anyone tried this, and if so, how did it work out for you?
