    Do we have anyone who has some experience with Photographer's Formulary's copper toner? I just received my box and I'd like to mix it for usage, but I'd like to know what kind of shelf life I can expect for stock solutions. I have an email out to PF but it's a weekend.

    I received a reply from PF. If mixed with distilled water, 6 months. If mixed with tap water with excess chlorine, few weeks.
