Reserve

nounStandard termCeramics & Glass

An area of a ceramic or glass piece intentionally left unglazed or undecorated.

A specific section of a piece where glaze, slip, or color is prevented from adhering, leaving the underlying body exposed. This is typically achieved by applying a resist material like wax, latex, or tape before dipping or spraying the piece. The technique highlights the contrast between the raw material and the finished surface.

Heard on the job

Make sure you paint a solid wax reserve on the foot ring so it doesn't fuse to the kiln shelf.

Insider tip

Wax resist is the most common way to create a reserve on the foot of a pot, as it burns away completely during the firing.
