Polymer clay is a synthetic, oven-bake modeling clay that's made from a plastic base of polyvinyl chloride (PVC). It's known for its versatility and pliability, and can be used for a variety of crafts, including jewelry, home decor, and sculpture.
Here are some things to know about polymer clay:
Composition: Polymer clay is made from a PVC base, along with fillers, pigments, and plasticizers. These components give the clay its flexibility, texture, softness, and color.
Working with polymer clay: Before baking, polymer clay is highly malleable and can be shaped and reshaped many times without deteriorating. You can condition the clay by kneading and warming it with your hands or a pasta machine to mix the materials evenly and increase its pliability.
Baking: Polymer clay is baked in a conventional, toaster, or convection oven at a low temperature, usually between 212°F–300°F. The baking time depends on the size of the piece and how long it takes for the heat to reach the center. Longer baking times result in a stronger bond and stronger clay.
Storage: Polymer clay should be stored in a cool, dry place away from direct sunlight and excessive heat. Once opened, it's best to store it in a polypropylene (PP) plastic bag or container. For long-term storage, a fridge or freezer is recommended.
