Raku Grog



    If you want a clay that forms easily yet has a gritty surface designed for large ceramic projects, this is our best formula. Raku with Grog can withstand the extreme changes in temperature in the Raku firing process. We have used several different clays to achieve a combination of small, medium, and large clay platelet structures, all of which interlock in the moist clay resulting in higher performance and fired durability.

    Note: Pieces fired in a Raku kiln are not food safe and should not be used for functional ware.
