Raku firing is a spontaneous, exciting technique.

 
RAKU, AN ANCIET METHOD OF FIRING POTTERY, WAS DEVELOPED IN  JAPAN DURING THE 16^TH CENTURY.  THE PIECES FIRED BY THIS METHOD WERE DESIRED BY TEA MASTERS FOR THEIR SPONTANIETY, ACCIDENTAL  FAULTS AND SIMPLE BEAUTY.

Raku is a very unique firing process.  The formula I use for my glazes contains a lot of copper carbonate.  The firing process begins by heating the piece in a kiln until it is glowing red-yellow (1850-2000 degrees F.)  At these temps the dry glaze materials on the surface of the pieces melts and flows.  I watch the progress of the firing through a peep hole in the top of the kiln.  When the proper temperature has been reached the flame in the kiln is reduced and the kiln is opened.  The piece is then removed with tongs and placed in an aluminum garbage can (reduction chamber) which is filled with combustibal materials.  On contact the material bursts into flames, often accompanied by a great deal of smoke.  The container is then closed and the flames rapidly consumes the oxygen.  The clay body blackens and the reducing atmosphere brings out the iridescent colors of the glaze.  I like to leave the pieces in the can to cool slowly but they may be quickly removed and quenched with water to stop the chemical process.  The timing of these steps is crucial and the end result is affected by many variables.

Unfortunately, many pieces do not survive the thermal shock and handling.  Many of the most beautiful are lost.

Raku fired pottery is porous and intended for decorative use only.  It should not be used for liquids unless a liner of some type is used.

I hope you enjoy your Raku piece as much as I enjoyed creating it.
