Is underglaze permanent?

Underglaze is generally considered permanent once it has been applied and fired onto a clay surface. The firing process fuses the underglaze particles with the clay, creating a durable and lasting bond.


Underglaze decorations are typically resistant to wear and fading, making them suitable for functional pottery and decorative pieces.

Firing Temperature

The permanence of underglaze can be influenced by the firing temperature. Firing at the recommended temperature for the underglaze ensures optimal results and long-lasting decoration.

Surface Protection

While underglaze is permanent, applying a clear glaze over the underglaze can provide an additional layer of protection and enhance the longevity of the decoration.


Underglaze decorations are a durable and lasting feature on clay objects, offering artists a reliable method for adding color and design to their ceramic creations.
