Yes, polymer clay can overcook if it is baked at too high a temperature or for an excessive amount of time beyond the recommended guidelines.
Effects of overcooking polymer clay:
- Color Changes: Overcooked polymer clay may become discolored, resulting in a burnt or darkened appearance.
- Brittleness: Extended baking can cause polymer clay to become overly brittle, leading to breakage and fragility.
- Texture Changes: Overcooked clay can develop a chalky or crumbly texture that affects its overall quality.
- Fume Release: Prolonged baking can potentially release harmful fumes, posing health and safety risks.
It’s essential to closely follow the manufacturer’s baking instructions and recommended temperatures to prevent overcooking your polymer clay creations.
