Abstract:
A raku kiln has a fire ring with a cylindrical sidewall and bottom made of refractory material with a kiln shelf supported a few inches above the bottom to enclose a space that is superheated by burners. A firing-chamber rests on the fire ring and is lifted by a two aligned pulleys on top of a pole which rotates to move the chamber out of the way. A vertical pole mates with tubes on the chamber for vertical guidance during raising and lowering of the chamber. Flanges on the lower end of the chamber allow adding an extension chamber.
