USING RECORD ALUM HARDENING CONVERTER

Unhardened emulsions are easily scratched when wet, and absorb moisture when dry. Adding RECORD Alum Hardening Converter to a fixer solution is one method of toughening emulsions to be more resistant
to abrasion and water absorption. If used correctly, it will increase archival permanence by protecting emulsions.

All B&W Films require alum hardening converter in the fixer.

Resin-Coated Prints require alum hardening converter to prevent scratching, and for a hard gloss on glossy finish papers.

Fiber-Based Prints should only be hardened if prints are to be dried on hot drums, or if emulsion is very soft. Fiber prints are hardened during manufacture, as well as by exposure to
heat, light, and air, so additional hardening may be harmful.

ARCHIVAL PERMANENCE

Alum Hardening will promote archival permanence if correctly timed and well-washed. Excess hardening will make prints brittle, curly and difficult to wash and tone to archival specifications.
Alum-hardened films and prints cannot be thoroughly washed with water alone. Use ARCHIVE Fixer Remover as directed when washing. Treatment with ARCHIVE
Fixer Remover will insure thorough washing and even toning. For complete directions on washing, please see instructions for ARCHIVE Fixer Remover.

Whenever a hardening fixer is used, BLOCK Stop Bath working solution must be used as directed before fixing to provide the correct acid environment.

One liter of RECORD Alum Hardening Converter will convert 66.6 liters of 1:9 RECORD Print Fixer working solution, or 33.3 liters of 2.8 RECORD Film Fixer working solution.
