The Story
For creating a patina using sodium thiosulfate, a recipe typically used on brass or bronze involves the following ingredients:
- Sodium Thiosulfate: 1/4 oz
- Ferric Nitrate: 2 oz
- Distilled Water: 1 quart
This recipe is a hot process, meaning both the solution and the metal should be heated. The process involves heating the solution to around 180 to 190°F, with the metal heated to about 200°F. After applying the solution to the metal, let it dry, then rinse with cool water. Repeat the process until the desired color develops. This method produces a blue-green patina on the metal.
