Does polymer clay break easily?

Polymer clay is a popular and versatile crafting material used to create a wide variety of projects, from intricate jewelry and figurines to decorative items and sculptures. One common concern among those new to working with polymer clay is whether it is prone to breaking easily. In this article, we’ll explore the factors that contribute to the strength and durability of polymer clay, as well as tips for preventing breakage and ensuring the longevity of your creations.

Strength and Durability

Polymer clay is known for its durability and strength when properly cured or baked. The baking process causes the clay to harden, making it sturdy and resilient. However, there are certain factors that can influence the strength of polymer clay projects:

  • Baking: Proper baking is crucial for ensuring the strength of polymer clay items. Underbaking can result in a softer, more fragile texture, while overbaking can lead to brittleness or discoloration.
  • Thickness: Thicker pieces of polymer clay are generally stronger than thin ones. When creating larger or structurally important components, consider using thicker layers of clay.
  • Design: The design and shape of your project can impact its strength. Projects with delicate or thin protrusions may be more susceptible to breakage.
  • Handling: Proper handling and care of finished polymer clay items can prevent unnecessary stress and breakage. Avoid dropping or applying excessive pressure to delicate areas.

Preventing Breakage

To prevent breakage and ensure the longevity of your polymer clay creations, consider the following tips:

  • Bake Thoroughly: Follow the manufacturer’s instructions for baking polymer clay to ensure it is properly cured. This step is crucial for achieving the desired strength and durability.
  • Reinforce: For projects that require added strength, consider reinforcing delicate areas with wire, armatures, or supports made from other materials.
  • Consider Design: When planning your design, take into account the structural integrity of the final piece. Opt for thicker sections or provide additional support where needed.
  • Handling: Handle your polymer clay creations with care, especially when they have delicate or thin elements. Avoid dropping or applying excessive pressure.
  • Storage: Store finished projects in a safe and protected place to prevent accidental breakage. Consider using padded or lined containers for added protection.


In conclusion, properly cured polymer clay is durable and can withstand normal handling without breaking easily. The strength of polymer clay projects depends on factors such as proper baking, design considerations, and careful handling. By following best practices for baking, reinforcing delicate areas, and handling your creations with care, you can create polymer clay items that are strong, resilient, and able to withstand the test of time.
