Silver Oxidizer Solution Stabilized Sterling Blacken Gel for Jewelry Making This silver oxidizer is designed to create a high-quality oxidized patina on sterling silver, fine silver, and copper-bearing metals such as brass and bronze. The gel can be applied directly using a brush and produces a range of finishes from rainbow tones to deep black. Apply the solution evenly, allow it to react, then rinse off when the desired color is achieved. Do not leave the bottle open; pour only the amount needed into a separate container. Do not return unused solution to the original bottle after use. Keep tightly closed and store out of reach of children.
