About the Raku Process
Raku firing involves the rapid heating and rapid cooling of clay pieces. Jim demonstrates this process every year at the Missouri Botanical Garden Japanese Festival. Pots thrown using specially formulated clay are rapidly fired to 1950 degrees fahrenheit, then removed from the kiln, placed in a reduction atmosphere for a few minutes, then rapidly cooled in a water bath. These pots go from red hot to the hands of audience members in the span of about 10 minutes.
