  • Patent number: 7357632
    Abstract: A kiln and method of firing a kiln are provided for use in connection with the firing of small-scale pottery firing. The kiln includes a kiln wall that defines a main kiln volume that is no larger than 60 cubic feet and is less than 10 cubic feet in one embodiment. The main kiln volume is structured to receive a pottery item for firing. The kiln further includes a combustion chamber that is thermally connected to the main kiln volume. A feeder automatically feeds solid fuel to the combustion chamber to reach and maintain at least a cone 10 temperature within the main kiln volume. In use, solid fuel is automatically provided to a combustion chamber at a controlled rate and is combined with combustion air in the combustion chamber. The solid fuel is combusted in the combustion chamber to warm a thermally-connected main kiln volume.
