|Sodium Thiosulfate (Hypo)||480||g|
|Mixing Instructions: When mixing Solution A, the hypo should be dissolved first completely, then add Potassium Alum with constant stirring and boil for a few minutes or until it turns milky. Add Solution B to Solution A with constant stirring, then allow to cool. Mix Solution C in two separate containers, one with Potassium Bromide, the other with Silver Nitrate. Then slowly pour the nitrate solution into the bromide solution while stirring briskly. Once the combined Solution A and B has cooled, add Solution C to the mixture. Allow the working solution to stand for a few hours prior to use, then reheat to 43C.|
|Dilution: Use undiluted.|
|Usage: Tone prints at temperature not exceeding 43C, agitating occassionally.|
NotesTo avoid split tones, ensure blacks are fully converted before removing print from solution.
WARNING: Silver Nitrate is hazardous and staining to skin and material. Wear gloves at all time to avoid skin contact. Ensure respiratory safety when handling.
