Popis:	The raw material is the major factor in limiting the speed of firing when using tunnel kilns of small cross section, such as the Prouty-type slab kiln. Raw materials vary greatly in the time required for water smoking, oxidation, and rapid shrinkage periods. The selection of materials that require small amounts of time can effect large reductions in firing time. Large reductions in firing time can be accomplished for slow-firing materials through control of the grog particle size distribution or through the addition of other clays or shales to the material. Some reductions in firing time can be obtained through the elimination of hygroscopic water prior to firing and through apportioning the available firing time according to the needs of the raw material. Such scheduling permitted the firing of certain full-size brick in 8° hours.
