Q

Why does the color vary where the glaze appears to have run?

A

The variations that look like flowing glaze are known as glaze runs. They arise from the way the glaze is applied and moves during firing, and are not defects.

In products such as the Mulet Line Cup shown here, we deliberately preserve the glaze's changes in shade and flow as part of each piece's character.

Glaze runs are distinct from overall color differences or dark speckles: they appear where the glaze has flowed. They give each piece its own character.
