A bstract The properties of ware, which were given different thermal treatments, have been compared. The tests include shrinkage, flexural strength, elasticity, thermal expansion, moisture expansion, microstructure, glaze stress, and glaze microhardness. The variations in these properties occurred as a result of differences in (1) supposedly similar firings, (2) the uniformity of the kiln from end to end, (3) the same firing in the cross section of the kiln caused by uneven heat distribution, (4) the rates of firing to the same cone deformation, and (5) repeated firings.
