This category is for the sites of independent artisans and potters offering online sales of Raku pottery. Japanese low-fired ceramic ware produced in Kyoto by the Raku family; famous for tea bowls and food dishes for use in the tea ceremony; originated in the late 16th century; this term also applies to wares made by a wide variety of amateur and professional potters in the tea community. Raku is a unique ceramic firing process. Each piece is sealed with a glaze that is high in copper. Each piece is fired in a ceramic kiln until the heat from the piece ignites paper, causing a reaction with the copper in the glaze.
