I think I read about the cyanotype process in a Kodak book (Creative darkroom techniques, I think), around 1980. It was rather hard to find the special chemicals involved. I tried to look for raw chemicals, however a lady chemist warned me that it would be not easy at all to get some result this manner, unless I would work in a chemistry laboratory with proper equipment and controlled purity ingredients. So, after a few years of failing attempts I did abandon those alternative techniques myself.
