What do you put over underglaze?

Applying a clear glaze over underglaze is a common practice in ceramics that helps seal and protect the underglaze decoration, create a glossy finish, and enhance the overall appearance of the piece.

Clear Glaze Application

When putting clear glaze over underglaze:

  • Ensure that the underglaze is completely dry before applying the clear glaze.
  • Apply the clear glaze in thin, even coats to avoid excessive thickness and potential running.
  • Consider using a brush, spray, or dipping technique to apply the clear glaze, depending on your preference and the desired effect.

Firing Process

After applying the clear glaze over underglaze, the piece is fired in a kiln according to the recommended firing schedule for the clear glaze. The firing temperature should be appropriate for both the clay body and the clear glaze.


Putting clear glaze over underglaze offers several benefits:

  • Seals and protects the underglaze decoration from wear, moisture, and handling.
  • Enhances the colors of the underglaze, making them appear more vibrant.
  • Provides a glossy and smooth finish that can be visually appealing and functional.


Using clear glaze over underglaze is a versatile technique that allows ceramic artists to create beautiful and durable pieces with enhanced decorative elements.
