Abstract: A kiln car includes freestanding straight rigid hollow members and freestanding angular rigid hollow members resting on the upper surface of the chassis of the kiln car. The rigid hollow members are of modular configuration and are arranged engaging together around and on the peripheral margin only of the upper surface of the chassis, with the angular members at the corner regions of the peripheral margin and the straight members extending between adjacent angular members. A cover extends over the enclosed area surrounded by the hollow members and there is insulating material within the enclosed area and within the hollow members. Support members for articles being fired extend upward from the upper surface of the chassis through the insulating material to support articles above the cover.

Abstract: A kiln assembly (10) with a tunnel kiln (12) having an entrance (14) and exit (16). Two parallel guideways (18) are provided extending through the kiln (12), each adjacent a side wall of the kiln (12). A plurality of car members (20) are movable respectively along either of the guideways (18) carrying support members (24) extending therebetween. Ware is loaded on to the support members (24) at the entrance (14), and is unloaede at the exit (16), are provided. Return guideways (22) are provided extending around opposite sides of the kiln (12) such that the car members (20) from the respective guideways (18) pass around opposite sides of the kiln (12) in a different spacing from when travelling through the kiln (12).
