Origins of Raku


The originator of raku in Japan was Sasaki Chojiro, who first produced raku pieces for the Japanese tea ceremony in the 16th century. He learnt the technique from his father Ameya, who was trained in the Ming Dynasty Sencai pottery tradition and was brought to Kyoto, Japan from China. The original chawan tea bowls were red and black and called ‘ Imma yaki ‘ These colors were favored because they represented the Yang elements which are grounding and support the tea ceremony principals of contemplation and austerity. This was further enhanced by using simple hand crafted forms while being balanced with the Yin forces of the abstract, asymmetrical shapes and the ethereal quality of the mysterious raku textures, appearance and colours.

Raku Procedures


Despite Raku being primarily decorative and rarely used for functional purposes, Raku has maintained a healthy level of popularity in the West. Some of the reasons for this are the diversity of  lustres and unique colours that are attainable, the creation of desirable crackle effects, the dramatic and exciting production process, the versatility of the glazes,  the unpredictable  “ one of a kind  “ outcomes and the relatively fast results that can be achieved. Adherents have also been drawn to Raku because of its deep tradition in the Japanese culture.
After the initial formation of the clay pieces which have then been dried, bisqued and cooled, they are ready for glazing. The glaze can be applied by spraying, brushing, dipping the piece in a glaze or drizzled.  After glazing the piece it is then re-fired in a raku kiln. The decorated pieces are fired again to 1800 F and within about an hour, when the desired melting of the glazes have been achieved, they are immediately removed while still glowing with special raku tongs ( the dramatic stage ) and quickly placed into a metal container filled with organic materials such as straw, leaves, pine needles, sawdust or paper, then quickly sealed to be smoked and cooled down.
The thermal shock causes the glazes to craze and carbon fills the cracks giving the glaze it’s distinctive crackle appearance, especially with the white based glazes. As the piece sits in the combustion chamber, the decreased oxygen causes a chemical reaction in the glazes, resulting in metallic, iridescent colors. One glaze can produce a variety of colors as flashing occurs in areas that are exposed to more or less amounts of oxygen. The colors achieved are spontaneous and unable to be replicated.
The natural un-glazed clay will become black from the smoking environment, while the glazed areas, due to the rapid cooling, will have the desirable crackle effect and/or look of lustres to the glaze. The piece is then cooled by quenching with water and cleaned. The glaze firing and reduction process generally takes between one to two hours. A raku kiln can be fired in 20 minutes, as opposed to 12 hours for a regular kiln. All these above factors have made Raku a popular choice for pottery workshops which has contributed to its growth.

Raku horsehair pottery vase –Letsgetmuddy, California

This vase was coated with terra sigillata , a refined slip coating that is used to give a high satin gloss without the use of a glaze and burnished with a small stone at least three times before its initial bisque firing. It was then fired in my raku kiln. When the temperature reached approximately 1500 degrees F. it was removed from the kiln and horse hair held up against the hot pot. The black markings you see are what was left behind.
As the pot cooled it was fumed with an iron solution that gives it a warm fiery hue.
