Thanks to all for their contributions to this thread.

Nicholas, many thanks for sharing the stabilizer formula! I'll give it a try! Where did you purchase the first two ingredients? I imagine the 28% a.a. is the same as Stop Bath for B&W chemistry?

Once the Chromoskadisic has been used, in your experience with Lumen prints have you noticed much, if any, color change further down the road?

Thanks again!
