Old junk CDs that you would normally throw away can be recycled into jewelry. When they're placed in the microwave, the heat and radiation transforms them into fragments that look like sparkling, iridescent pieces of glass. These fragments can be used as pendants or fashioned into pins, bracelets and earrings. Different types and colors of CDs produce different effects when microwaved, adding variety to what you can create.
Place a CD upside down on a microwave-safe glass or ceramic plate. Microwave it on high for five to six seconds. This will cause the CD to crack and become brittle. According to editors at Crafty Crafty, your CD will spark in the microwave, so don't be alarmed.
Use sharp scissors or your hands to cut or break the CD into the shapes you want to use to make jewelry.
Line a baking pan with aluminum foil and preheat the oven to 400 degrees F. Place your CD fragments on the baking sheet and place in the oven.
Bake until the fragments take on their iridescent color and soften. Check on your pieces every couple of minutes to avoid overcooking them. Approximate baking time is five to ten minutes, depending on size of the pieces and the oven used.
Remove the pieces from the oven and take them off the baking tray to cool. Use the drill or a rotary tool to drill holes into the pieces where you plan to add jewelry hardware.
Use fine sand paper to smooth any rough edges. The pieces are now ready to add to necklaces and bracelets or to be turned into earrings, brooches and other types of jewelry.
