RE: Is there a way to save old cyanotype paper?
Hi Spike, No, soak in water with sodiumcarbonate, a cyanotype will bleach in alkaline water, so if your stored paper will still have a blue stain after soaking in plain water it means there has been some auto-exposure due to the long storage. I would be surprised if that would NOT be the case, so I would dump it in the water plus sodiumcarbonate right away, I guess 2 or three successive baths are needed to get it realy back to paper white, perhaps best to give it a final rinse in (distilled) plain water, Good luck, Cor > -----Original Message----- > From: Spike MacGee [mailto:spikemacgee@gmail.com] > Sent: dinsdag 27 maart 2007 14:16 > To: alt-photo-process-l@usask.ca > Subject: Re: Is there a way to save old cyanotype paper? > > Hi Trevor and Robert, > Both good ideas, I will try both. > Trevor: Do you mean soaking with sodiumcarbonate AFTER the final wash? > Regards, > Spike
