Can Polymer Clay Stay in Water?
Yes, baked polymer clay can withstand water, but unbaked polymer clay should not get wet.
The interaction between polymer clay and water depends significantly on whether the clay has been cured (baked) or is still in its raw, pliable state.
Unbaked Polymer Clay and Water
According to Sculpey, polymer clay should not get wet while you're working with it. Exposure to water before baking can negatively impact the clay's properties and the final outcome of your project, potentially affecting its durability and texture.
Here's why avoiding water is important during the sculpting phase:
- Water can interfere with the clay's consistency.
- It may make the clay sticky or difficult to handle.
- Moisture trapped inside could affect curing.
Baked Polymer Clay and Water Resistance
Once your polymer clay creation has been properly cured (baked) in a home oven, the situation changes entirely. The reference states that once baked, the final piece can withstand water. This makes baked polymer clay suitable for items that might come into contact with moisture, such as jewelry, ornaments, or decorative items.
Key Difference Summary:
| State of Clay | Can it stay in water? | Reference Insight |
|---|---|---|
| Unbaked (Raw) | No | Should not get wet while you're working with it |
| Baked (Cured) | Yes | Once you've made your craft and baked it... the final piece can withstand water. |
Practical Applications
Because baked polymer clay is water-resistant, it opens up possibilities for various projects:
- Jewelry: Earrings, pendants, and beads can handle occasional splashes or rain.
- Ornaments: Suitable for indoor or outdoor display where they might encounter moisture.
- Home Decor: Items like coasters or decorative pieces can be wiped clean.
While baked polymer clay is water-resistant, it's generally not recommended for items that will be constantly submerged in water for extended periods, such as items for aquariums or outdoor fountains, unless sealed with a specific waterproof coating designed for that purpose.
