Re: Anybody experimented with Argyrotypes?
Paul, have you tried a surfactant? (Tween or something like that. Never did for Argrotypes but I was using Ilfotol w/o any negative effects for Classic Cyanotypes.) Any sensitizer with AFC will have difficulties in soaking into the paper, maybe you were experiencing just that? (Indicated by loosing image - if it's in the form of bleeding that is...) Were you using a hair dryer à la platinum / kallitype? It's best to let the paper in peace after coating for at least 10 minutes, to let the sensitizer soak in. All above in case of loosing image due bleeding. Which paper was that BTW? Sam, were you diluting 1:1 or adding distilled water to make the coating solutions volume 2x? For instance if your nominal coating soln. amnt. for 8x10" is 3ml you were using 1.5ml sensitizer + 1.5ml water or was that 3ml sensitizer + 3ml water? If the latter maybe the extra water was helping the coating solution penetrate into the paper. If the former than that is a very interesting and useful piece of information!
