A kiln car comprising a wheeled base having a substantially flat horizontal upper surface and carrying a superstructure comprising a plurality of superimposed rectangular tiers each composed of at least one plate-like batt of refractory material, the tiers being vertically spaced from one another and from said base by supporting props of refractory material located at least at the four corners of the tiers, each prop having substantially flat top and bottom surfaces, wherein the improvement comprises at least one disc of refractory material interposed between the lowermost tier and each of its supportIng props, both the under side of said tier and the top of each of its supporting props having a substantially flat surface in contact with said interposed discs, and at least some of said discs having one convex side making substantially point contact with an opposing surface, and one substantially flat side.
