Abstract
A gas or electrically heated kiln furnace in which the hearth is stationary and an outer shell or wall with a door for access rotates around a stationary hearth. Loading and unloading is accomplished by rotating the outer shell to align the door with a position where a workpiece is to be inserted or removed. The kiln can be used as an up draft or down draft kiln, as a single chamber or a progressive chamber kiln. This kiln uses minimum floor space in that a circular shell is not rolled back but rotated about a hearth, around a vertical axis.
