Yes, polymer clay sets hard after it undergoes the baking process. Unlike traditional air-dry clays that dry by moisture evaporation, polymer clay cures and becomes solid through a chemical reaction during baking.
Key points about polymer clay setting hard:
- Curing: Baking polymer clay triggers a cross-linking reaction among its components, resulting in a firm and durable texture.
- Strength: Properly baked polymer clay becomes strong and rigid, suitable for a variety of crafting and artistic projects.
- Stability: Once cured, polymer clay maintains its shape and hardness over time without the risk of reverting to a softer state.
It’s important to follow the recommended baking instructions provided by the manufacturer to ensure optimal curing and achieve the desired hardness for your polymer clay creations.
