Raku Glazes

Explore our collection of raku glazes, featuring specialist ceramic glazes developed to create the dramatic effects that make raku pottery one of the most exciting firing techniques in ceramics. Raku glazes are renowned for producing metallic lustres, crackle patterns, smoky reduction markings, copper flashes, iridescent colours, and reactive surface effects that vary from piece to piece.

Our range includes both Vitraglaze Raku Glazes and Spectrum Raku Glazes, with popular colours and finishes. These specialist formulations are designed specifically for alternative firing techniques and offer unique results that cannot be replicated through conventional electric kiln firing. 

Ideal glazes for decorative pottery, sculpture, ceramic art, garden ceramics, and exhibition work, where individuality and surface character are highly valued. Whether you're experimenting with raku for the first time or refining an established firing practice, our collection offers a wide range of colours, crackle finishes, metallic effects, and reactive glaze surfaces to explore.
