Here's the set-up. The positive red wire and alligator clip gets attached to the copper wire holding my two earrings with the hand drawn swirls. The negative black wire and clip attaches to the copper wire holding a scrap piece of copper. A jar is filled with warm water saturated with salt. The two wires holding the copper pieces are put into the salt water.
Immediately you see bubbles forming and gradually the salt water turns a red brown color.
I left the earrings in for an hour, and there was definitely a beautiful etched pattern. Here they are out of the solution. They need to be washed and scrubbed.
Here are the finished earrings below. If you'd like to learn more about this process, please contact me and I'll give you the information I have. It's so easy and rewarding!
