How strong is polymer clay once baked?

Polymer clay is a versatile and popular medium used for a wide range of artistic and crafting projects. One common question that arises is how strong polymer clay becomes once it’s been baked. In this article, we’ll delve into the strength and durability of polymer clay after baking, and discuss its suitability for various applications.

1. Solidification through Baking

Chemical Transformation:

From pliable to solid:

When polymer clay is baked at the recommended temperature and duration, a chemical transformation occurs. The heat causes the plasticizers in the clay to evaporate, resulting in the clay hardening and solidifying. This transformation is essential for the clay to achieve its characteristic strength.

2. Resistance to Breakage

Durable and Resilient:

Withstanding pressure and stress:

Baked polymer clay is surprisingly strong and can withstand a fair amount of pressure and stress without breaking. This makes it suitable for a variety of applications, including jewelry making, sculpting, and functional items. However, while polymer clay is strong, it’s important to handle and use the finished pieces with reasonable care to ensure their longevity.

3. Flexibility and Bendability

Flexibility without Fragility:

Bending without snapping:

Despite its solidity, baked polymer clay retains a degree of flexibility. This flexibility sets it apart from traditional ceramics or fired clay, which can be brittle and prone to shattering. Baked polymer clay can bend, twist, and flex without easily snapping, making it a versatile material for projects that require both strength and resilience.

4. Wear and Tear

Resistance to Wear:

Handling and usage:

Baked polymer clay exhibits good resistance to wear and tear, making it suitable for functional items such as buttons, utensils, and even decorative pieces that may be touched or handled frequently. However, over time and with extended use, polymer clay items may show signs of minor wear, such as small scratches or scuffs.


Baked polymer clay is remarkably strong and durable, capable of withstanding pressure, bending, and everyday handling. Its unique combination of strength and flexibility makes it an excellent choice for a wide range of creative projects, from jewelry and sculptures to functional items and decorative pieces. By understanding the solidification process that occurs during baking and appreciating the material’s resilience, artists and crafters can confidently create beautiful and long-lasting creations that showcase their skills and imagination.
