Hi All, thanks for the replies and the comments.

I feel that my bleaching solution was way to strong (0.5 teaspoon to 1 litre of water) as the reaction was very quick, too quick to easily control the level of bleaching with any thinking time. So would suggest a weaker mix.

Other than the original, my preference so far is to go straight from the rinse into the coffee bath. In future I will keep a close watch on the colour change and take out as soon as I see the colour change, this I'm sure will reduce any staining of the paper, which is fairly minor in my original experiment.

When I get some, my next experiments will be on actually trying to change the colour of the paper using food colouring, to see if the paper will absorb that and how it will alter the cyanotype blue. Although my reservation is that this will be detrimental to the longevity of the print.

Have also pondered the chances of using water colour paint washes within areas of a print, still plenty of time, looks like we're not going anywhere soon

Ian
