To take the edge off a little I thought rather than using liver sulphur which gives quite dramatic results and quickly, I'd go for the subtle approach and 'egg' oxidise.
|Start with the piece you want to oxidise - it works best with copper and sterling silver|
|Hard boil an egg|
|While piping hot, quarter the egg (leaving on shell), and place with your item in a container with airtight lid|
|Put lid on and wait till egg has cooled. If you haven't quite got the effect you want you can reheat the egg in a microwave for around 20 seconds and pop item back in again till cooled, you can repeat this as needed.|
|I didn't want a dark look, simply to mute the orangey bare copper and create contrast in the curves, so I left my bracelet in for only a short amount of time and used a polishing cloth on the top curves of the thicker wire.|
Much better I think!
