Preparation and Safety Guidelines

Tools Needed
  • Aluminum foil
  • Polymer clay
  • Polymer clay scraps
  • Silicone spatula
  • Extruder
  • Small nozzle

  • Acrylic paint
  • Acetone
  • Napkin
Safety Guidelines
  • Polymer clay needs to be baked according to the manufacturer's instructions to harden. Improper baking can result in a brittle or soft topper.
  • Always work in a well-ventilated area, as some polymer clays may release fumes during baking.
  • Avoid touching your face or eyes while handling unbaked polymer clay. Wash your hands thoroughly after handling.

Step-by-Step Instructions

  1. Create the Bases

    • Create the base using aluminum foil. Form two separate parts for the groom (legs and body) and one whole piece for the bride.
    • Create the base for the figures using aluminum foil, cover with polymer clay, then add a white clay layer. Ensure stability.

Tips

  • Use liquid polymer clay to improve the grip of the clay on the aluminum foil base.
  • For thicker clay layers, baking for an hour is recommended.

Common Mistakes to Avoid

1. Uneven baking

Reason: Inconsistent thickness of the clay leads to uneven baking and potential cracking or warping.
Solution: Ensure your clay is rolled to a uniform thickness before baking.

2. Clay cracking during baking

Reason: Baking at too high a temperature or for too long, or using damp clay can cause cracking.
Solution: Follow the recommended baking temperature and time for your polymer clay brand, and ensure your clay is completely dry before baking.

3. Colors bleeding together

Reason: Insufficient baking or using clay colors that are not fully cured before combining them can result in color bleeding.
Solution: Bake each color separately until fully cured before combining and baking the final piece.

FAQs

How do I ensure my polymer clay cake topper is food safe?
Polymer clay itself isn't food safe, so it shouldn't directly touch the cake. Always apply a food-safe sealant (like a varnish specifically designed for food contact) after baking and completely curing the clay. This creates a protective barrier preventing contact with the cake.
