| Part A | ||
| Water | 4000 | ml |
| Sodium Thiosulfate (Hypo) | 480 | g |
| Potassium Alum | 120 | g |
| Part B | ||
| Water | 30 | ml |
| Potassium Iodide | 1.4 | g |
| Part C | ||
| Water | 30 | ml |
| Potassium Bromide | 1.4 | g |
| Water | 30 | ml |
| Silver Nitrate | 1.4 | 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. |
Notes To 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. |
