We recommend using a thermal shock-resistant Raku clay body (will help reduce the incidence of cracking). As glaze application, glaze fire temperature, combustible materials, firing process and kiln type vary from artist to artist, final results will vary. Our product testing involved a Raku clay body, Raku kiln and straw for our reduction material.

Raku can be done in a gas or electric kiln environment as well. Maturing the glaze at lower temperatures and using different combustible materials such as sawdust, newspaper, straw, etc will greatly influence the colors and look of the glaze. Minimizing the distance between the kiln and the reduction container will also enhance color.

Proper safety processes and personal protective equipment are very important when doing Raku as you are exposed to high heat, flames and smoke. Always wear heat and fire protective clothing and fireproof gloves. Do not open or insert tongs into an electric kiln without shutting off. Reduction process should take place outside of building due to flames and smoke.
