Review Summary




Before you finalize your black and white film or paper processing, consider the Record Alum Hardening Converter, a fixer additive specifically designed to enhance the durability and longevity of your photographic works. This product is expertly formulated to toughen emulsions, making them more resistant to abrasion and moisture absorption, thereby increasing their archival permanence.
Unhardened emulsions can be easily scratched when wet and tend to absorb moisture when dry. However, with the application of this efficient alum hardening converter in the fixer, you can significantly improve the resilience of your emulsions. This high-quality product is a must-have for all black and white films, as they require alum hardening in the fixer to ensure their longevity and quality.
For resin-coated prints, this reliable fixer additive is essential to prevent scratching and to achieve a hard gloss on glossy finish papers. Fiber-based prints, on the other hand, should only be hardened under specific circumstances, such as when prints are to be dried on hot drums or if the emulsion is exceptionally soft.
While fiber prints are hardened during manufacture and by heat, light, and air, additional hardening using this durable alum hardening converter can sometimes be harmful. However, when correctly timed and well-washed, alum hardening can significantly promote archival permanence. Be aware that excess hardening can make prints brittle, curly, and difficult to wash and tone archivally.
To ensure thorough washing and even toning, treatment with ARCHIVE Fixer Remover is recommended. Please note that due to hazardous material regulations, this item can only be shipped by UPS GROUND, with no air freight option available.
