Formulary's PMK Pyro Film Developer is a Pyro Metol Kodalk formula developed by Gordon Hutchings.  Kodalk is a trade name for balanced alkali (sodium metaborate). Unlike most developing agents, pyrogallol stains the gelatin.  The stain is characteristic and desirable, and tans and toughens the gelatin allowing the use of alkaline non-hardening fixers such as Formulary's TF-4 archival rapid fixer.

The chemicals in the kit are used to make two stock solutions that dilute to 25 liters of working solution.
