My newest love is etching brass and copper. I started out with a small battery setup and some saltwater. The results were so cool I had to learn more! I have graduated now to a proper power supply, and I am also using the chemical technique using ferric chloride. The bracelets shown here were made using the ferric chloride.
These delicate little bracelets - which are not really delicate, they just look dainty - are available in my shop for just $18 each.
