 Raku – a brief insight

The firing technique of “RAKU” ware was first developed in Japan in the late Sixteenth century. The first items ever Raku fired were tea bowls.

The Raku firing technique utilizes a rapid rise in temperature in a propane fired kiln (Oxidised firing). The raku items are taken out of the kiln at glaze maturity and placed in an air tight container containing shredded newspaper and sawdust (Reduction firing). A short time later the raku items are taken out of the air tight container and either air cooled or sprayed or dipped in water.

The raku firing technique and the reduction cause the items to develop vivid colours and a copper sheen.  Fire and smoke create matt black surfaces in unglazed areas. Oxygen deprivation, the fire and temperature changes cause the glazes to fully or partially reduce and cause interesting colours or patterns of colour or areas of bronze, copper or silver to develop. As a result the items have wonderful vivid colours and sheen. Fire and smoke create the matt black surface areas. Slight variations in glaze thickness cause the glaze to react and change colour. Oxygen deprivation (reduction) and temperature changes determine the shades of the colours that develop. As a result, no two items are exactly alike.

The word Raku, when loosely translated, can mean joy, enjoyment, pleasure, comfort, happiness or contentment.
