Using Blix part A and B separately

athbr · Jun 12, 2019

Can the blix that comes in powder C41 chemistry be used separately as bleach and fix?

If not, could the necessary adjustments be made using reagents?

For reference, here is the composition information for parts A and B for Cinestill powder C41 kit as per the safety data sheet:

Part A (this is likely the fix):
Ammonium Thiosulfate 90-95%
Sodium Carbonate 3-5 %

Part B (this is likely the bleach):
Ferric Sodium 60-70%
Sodium Sulfite 10-15%

No. See the posts by Rudeofus here on PHOTRIO regarding this. And, there is more in these parts than you list.

I imagined the lists were incomplete PE.

Sadly the thread in question "Converting C-41/E-6 BLIX into Separate Bleach and Fixer" has a link that expired. But based on the snippet quoted in Rudeofus post it seemed the link was a set of instructions to convert the blix into separate bleach and fix.

Are there other sources for the information in question?

Start a conversation with Rudeofus - he may very well be able to update the link.

I just realized the whole thing was there if you just switched to "Overview".

Please disregard my coffee-worn ignorance. Probably need to leave the darkroom for now.
