Raku - the process |
Raku is a technique originating in Japan during the sixteenth century known to potters for its exciting process and unpredictable outcome. Chadston Gibbs, of CRG Clay, uses a Western or American version of Raku firing, popularized in the 1950s in the United States. This firing process involves quickly heating pieces to high temperatures then cooling them immediately. As the pictures depict, the pottery pieces are removed from heat when they are bright red, placed in an aluminum cans filled with combustible materials, in this case shredded newspaper, causing the chamber to smoke while reducing heat. This firing style blackens raw clay and alters glaze colors because of the reaction between oxygen/carbon monoxide and the clay minerals. This firing process prohibits items from being food safe. Washing is not recommended.
