What can I put on copper beads to keep them from discoloring?
Mona Lisa™ Metal Leaf™ top coat sealant seals and protects metal beads. Apply a thin coat of Mona Lisa Metal Leaf with a paintbrush then and let dry approximately 15 to 30 minutes for a finish that protects your beads.
You can also prevent tarnish while your beads are in storage with Shine-On™ Coppertex® strips. These paper strips can be placed in bags or organizers with your beads and jewelry to help inhibit tarnishing.
