As is the same with Kodalith.
If anyone out there gets their paws on some, it is fantastic stuff. It only gets better with age.
I mix the Kodalith as 1 part A, 2 parts B, to 30 parts water, then I expose it to open air for two days before using. Exposure times run around 10-20 minutes with development anywhere from 30 minutes to and hour and a half depending on the level of exhaustion.
The best papaers I found for Kodalith are Fotokomeka, Slavich, and Kentona.
Illfod is a no go. It works, but is not favorable.
Thanks for the tip on Arista.
