The impact of rebaking on the strength and durability of Polymer Clay

One of the key advantages of rebaking Polymer Clay is that it increases the strength and durability of your work. This is especially true if you plan on making items that need to stand up to frequent handling or exposure to moisture, such as jewelry or kitchenware. Reheating polymer clay can also help create a more unified look and feel throughout your piece by helping to blend colors together and reduce visible seams.


The primary way in which rebaking affects the strength and durability of polymer clay is by forcing out any air bubbles inside the clay before it cures completely. Air bubbles create weak spots within the material that are prone to breaking when handled or exposed to high temperatures. By removing these during baking, you’re left with a firmer, more durable item.

The temperature at which you bake your clay also plays an important role in determining the strength and durability of your work. If a piece is baked for too long or at too high of a temperature, it can cause the polymer to become over-hardened and brittle, resulting in a weaker finished product. On the other hand, if it’s not heated long enough, it won’t fully cure and may be prone to shattering or breaking easily when handled.

To ensure the best results, you should always refer to the manufacturer’s instructions for baking temperatures and times. Additionally, some materials such as metal molds can require additional baking steps such as glazing before being used with polymer clay.Polymer Clay

Overall, rebaking Polymer Clay is a great way to improve the strength and durability of your work while also helping to create a unified look.
