Other than that, I just use a plain water stop bath and regular Kodak Fixer.
I started by making a test print to check for exposure times.
This is the same gelatin as found in products such as Jello.
This means that the light sensitive chemical mixture in paper and film are suspended in gelatin with a few added little things before being applied to the base paper or plastic during manufacture.I won’t go over the math as that is super boring, but this means that a normal exposure of two seconds would be just over one minute on this paper.
