Raku is an ancient quick firing technique which yields beautiful results with an interplay between smoke, fire and glaze.  Pieces are glazed and fired to around 1906°, immediately the kiln is opened and pieces are removed to be placed in a reduction chamber which contains combustibles.  These combustibles assist in altering the glaze composition by creating smoke known as reduction.  This reduction process contributes to the blackening of the clay body as well as intensifying the color of select glazes.
