The Japanese symbol for "Raku" denotes "Enjoyment of Leisure" or "Contentment."  This is appropriate as the process of making Raku Beads derives from an ancient Japanese method of firing pottery which creates pleasing and varied effects. Clay resistant to shock is necessary as the beads undergo several rapid changes in temperature. After the beads are created, carved, and finished, they are fired once (bisque), then decorated after they cool. After a second firing to 1850 degrees Fahrenheit, they are carefully removed while still red hot from the kiln and placed in a container of combustible material which ignites. Covering the container oxidizes the glazes thus producing the vivid colors associated with Raku work. The fire and smoke create the matte black surfaces of areas that are not glazed. Achieving desired effects with glazes requires quick work as the temperature is critical to success. Glazes vitrify within a certain temperature range and slight variations may completely change colors and sheen.
