This fun stuff is a great way to create unique jewelry and is simple to use. DeCoRé dries within 24 hours and requires no baking. Simply mix, mold and let harden. This clay will adhere to almost any surface including wood, metal and glass. If the clay becomes hard or clumpy, simply microwave for 2 to 5 seconds. Wipe your final design with a damp cloth to remove residue and give it a nice polish.
