Is polymer clay permanent?

Polymer clay has gained immense popularity among artists, crafters, and hobbyists for its versatility and ability to create intricate and lasting artworks. When working with polymer clay, one common question that arises is whether the resulting creations are permanent. In this article, we’ll delve into the concept of permanence in relation to polymer clay and explore the factors that contribute to its long-term stability.

The Nature of Polymer Clay

Polymer clay is a synthetic material composed primarily of PVC (polyvinyl chloride) particles and a liquid plasticizer. When properly cured through baking at specific temperatures, polymer clay undergoes a chemical reaction that transforms it from a pliable state into a solid and durable material. This curing process creates a stable and enduring structure that is less susceptible to physical changes compared to air-dry clays or other modeling materials.

Longevity and Durability

When properly cured and handled, polymer clay creations can be quite durable and long-lasting. The level of permanence achieved with polymer clay largely depends on several factors:

  • Curing: Proper curing is essential to achieve the full hardness and durability of polymer clay. Inadequate curing can result in pieces that are more prone to breaking or becoming brittle over time.
  • Protection: Applying a clear sealant or varnish to your polymer clay creations can provide an additional layer of protection against wear, moisture, and UV radiation, enhancing their longevity.
  • Storage: Storing polymer clay artworks in a dry and stable environment can help prevent unnecessary stress, warping, or deterioration over time.

Factors That Affect Permanence

While polymer clay is relatively permanent, it’s important to consider a few factors that can influence its long-term stability:

  • Exposure to Sunlight: Prolonged exposure to direct sunlight and UV radiation can affect the colors of polymer clay and may lead to fading over time. Using UV-resistant sealants or displaying pieces away from direct sunlight can help mitigate this effect.
  • Physical Handling: While polymer clay is durable, rough handling or excessive stress can potentially cause pieces to break, chip, or crack. Treating your creations with care can help maintain their integrity.
  • Environmental Factors: Extreme temperature changes, humidity, and moisture can impact the stability of polymer clay. Proper storage and handling can help minimize the effects of these factors.


In conclusion, polymer clay can be considered a permanent medium when properly cured, handled, and maintained. Its durability, resistance to physical changes, and potential for long-lasting beauty make it a popular choice for creating various artworks and crafts. By following proper curing techniques, using protective measures such as sealants, and considering environmental factors, you can ensure that your polymer clay creations remain vibrant and intact for years to come.
