Photographers' Formulary 03-0170 Residual Silver Test

Photographers' Formulary 03-0170 Residual Silver Test

• Photographers' Formulary Residual Silver Test is used to determine if any silver ions remain in a print or on a film strip after fixing.

When the Photographers' Formulary Residual Silver Test solution is applied to photographic material the sulfide ions in the solution react with any residual silver ions in the material forming a yellow stain indicating the fixing process is inadequate. The chemical in the kit makes a stock solution which is diluted 1:9 to make more than 1 liter of working solution. The stock solution shelf life is 3 months. The working solution lasts 1 week. For the creative photographer, darkroom enthusiast, and professional photographer Photographers' Formulary provides options for photographic work you have heard about in easy-to-use kits.
