Amaco CR-54 Purple Stoneware Glaze

Amaco CR-54 Crawls Purple

Purple from Amaco’s Crawls series is a glossy violet glaze that purposefully crawls during firing, forming raised shapes of various sizes and forms. This creates a surface with unpredictable, natural patterns that give each piece a unique texture and look.

Crawls glazes take advantage of an effect traditionally considered a defect: glaze crawling. During firing, the glaze pulls back, exposing the underlying clay body or a layer of glaze beneath. Every firing thus yields a unique, spontaneous result.

The Crawls can be used alone or applied over underglazes and other Cone 5/6 glazes, especially appealing over glazes from the Amaco Celadon series to create depth and contrast.

Note on food safety

The Crawls glazes are not food-safe when applied alone. If they are applied over an Amaco Celadon glaze, they are considered food-safe. For tableware and surfaces that come into contact with food, we therefore recommend always using the Crawls over a Celadon glaze.
