Rakumaking

Rakumaking is the process of manufacturing raku, a type of ceramic art that originated in Japan in the 16th century. The process involves creating a piece of ceramic ware and then firing it in a kiln at a low temperature, followed by a quick firing in a reduction atmosphere.

The process begins with the creation of a ceramic piece, usually using techniques such as hand-building or wheel-throwing. The piece is then covered with a layer of glaze, which is a mixture of materials such as clay, silicates, and metal oxides. The glaze is applied in a way that allows it to penetrate the ceramic body, creating a rich, crackled surface.

The piece is then placed in a kiln and fired at a relatively low temperature, usually around 1800-1900 degrees Fahrenheit. This firing stage, known as the "bisque" firing, is designed to achieve partial vitrification of the ceramic body.

Once the piece has been bisque-fired, it is removed from the kiln and placed in a special reduction chamber. The reduction chamber is designed to rapidly reduce the oxygen levels around the piece, causing the glaze to crackle and create a distinctive texture. This process, known as "reduction firing," is a critical step in creating the characteristic look of raku ware.

The final firing stage is relatively short, lasting only a few minutes. The result is a piece of ceramic art with a beautiful, crackled surface and a rich, earthy color.
