An attempt was made to determine by experiment the best conditions with respect to temperature, circulation of air, and its relative humidity, by which to obtain shorter drying time, a minimum of war page, and cracking of the ware generally. Also, a very tender clay was given special study with the object of finding a set of drying conditions by which its extreme tendency to warp and crack would be reduced to a point that would permit practical use of this clay for terra cotta body. The drying time was reduced about 407, by increasing the steam pressure in the heating coils and apparently some showing made in reducing the tendency of the ware to warp and crack. A schedule of drying that gave satisfactory results with the tender clay was developed on an experimental scale, but could not be applied to the factory driers because of limitations in the heating and circulation equipment.
