Polymer clay is generally non-porous and will not readily absorb water, which means it should not sink in water.
Characteristics of polymer clay in water:
- Floats: Polymer clay is denser than water, causing it to float rather than sink.
- Water Resistance: Polymer clay’s resistance to water absorption contributes to its durability and longevity.
- Buoyancy: Even larger polymer clay creations are likely to remain buoyant when placed in water.
However, it’s important to note that polymer clay can become more susceptible to damage when soaked in water for prolonged periods, as excessive moisture can affect its structural integrity.
