Raku is an ancient firing method of the orient. What makes this technique unique is that the pieces are removed from the kiln while white hot (approx. 1600 degrees F.) and then placed in a bin full of combustibles. The temperature shock creates the crackled effect in the glaze, and the black smoke fills the cracks to make interesting and unexpected geographic patterns. The ideaograph for Raku means; peace, contentment, pleasure and happiness.
