    Ilfochrome chemicals

    I was recently given 3 boxes of 16x20 Ilfachrome. Is there any way to process this? Does anyone make chemicals for this or can you manufacture the chemistry needed? I really hate to see this go to waste

    Hi Michael,

    You might try talking with Frank Green at the LAB CIBA in Burbank, California:

    http://lab-ciba.com/index.html

    He still prints CibaChromes|IlfoChromes and may have some ideas.

    I probably have enough unopened P3 chem on hand, but it would be a real headache to ship (hazmat - the pro liquid kits contain strong sulfuric acid). But will the paper still be good? Has it been frozen the whole time?

    “hazmat - the pro liquid kits contain strong sulfuric acid”

    So that is what that suffocating yellow cloud that came out when I opened my 16x20 Agnecolor processor!

    Boy, was that hard to dissipate! Never tried doing that again!

    The small amateur kits came with sulfamic acid powder. The pro bleach was mainly liquid sulfuric - very nasty on processing machines, drainpipes, lungs, and business licenses. But since I was a low-volume user running drums outdoors with one-shot pro chemistry, it was an easy problem. Just drain the drum after the bleach step into a bucket containing a little baking soda - instantly neutralized.

    There was someone over on photrio that was working on formulating the bleach though I've not heard back from him in a long time. I too have some stored paper and no way to use it :-/
