How do you oxidize wire?

Published in Metal Oxidation 2 mins read

Oxidizing wire can be achieved using various methods, often involving chemicals that accelerate the natural oxidation process (tarnishing). One method is to use a solution of liver of sulfur.

The referenced video excerpt describes a process where a non-food-use mixture is created that turns yellow. The wire is then placed in this solution for a few seconds to oxidize it. While the excerpt lacks specific details, this points to a chemical oxidation process. Liver of Sulfur is a common chemical to use.

Here's a general process for oxidizing wire with liver of sulfur:

  1. Safety First: Wear gloves and eye protection. Liver of sulfur can irritate the skin and eyes. Work in a well-ventilated area.
  2. Prepare the Liver of Sulfur Solution: Mix a small amount of liver of sulfur (available as a solid or gel) with hot water. Start with a small amount of liver of sulfur, as too much can prevent the oxidation from properly occurring. The solution should be a pale yellow to light brown color. Do not use containers used for food preparation.
  3. Clean the Wire: Ensure the wire is clean and free of oils or fingerprints. Use soap and water, followed by a rinse and thorough drying.
  4. Submerge the Wire: Carefully submerge the wire in the liver of sulfur solution.
  5. Monitor the Oxidation: Check the wire frequently. The oxidation process happens quickly, usually within seconds to minutes. The wire will darken as it oxidizes.
  6. Rinse and Dry: Once the desired level of oxidation is achieved, remove the wire from the solution and rinse it thoroughly with cool water. Pat dry with a soft cloth.
  7. Seal (Optional): To prevent further oxidation and protect the finish, you can apply a sealant specifically designed for metals.

Important Considerations:

  • Ventilation: Proper ventilation is crucial when working with liver of sulfur, as it releases sulfur dioxide gas.
  • Disposal: Dispose of the liver of sulfur solution properly according to local regulations.
  • Metal Type: The oxidation process and the final color can vary depending on the type of metal wire used (copper, silver, etc.). Liver of sulfur works well with copper and silver.
