You can cover metal clay with gold leaf to make it look as if it is made of gold.
When you sculpt an object out of polymer clay, you can make it look as if it has been molded from a precious metal by using specific techniques. One option is to create your sculpture using a metallic version of polymer clay, then applying gold leaf to the baked sculpture to make it appear as if it has been made from gold. You can purchase metallic polymer clay and gold leaf at any art supply store.
Instructions
1. Sculpt the form you want to create out of metallic polymer clay.
2. Place the sculpture onto a cookie sheet.
3. Bake the sculpture in a 200 degree Fahrenheit conventional oven for 10 minutes. Allow the sculpture to cool completely.
4. Peel the backing off of a sheet of gold leaf.
5. Lay a butter knife over the top edge of the gold leaf and twist the knife slightly to curl the leaf over the knife.
6. Lift up the gold leaf slowly so that it does not tear.
7. Lay the sheet of gold leaf over the sculpture.
8. Dab the gold leaf into place using a soft watercolor brush.
9. Repeat this process until the entire sculpture has been covered with the gold leaf.
