Studies in Glazes

C. Purdy Ross, F. Krehbiel Junius

Description

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. One fact in connection with the time-temperature treatment was developed in these studies, which permitted the shortening of the total time required for each burn, viz., that the rate of raising heat did not seem to affect the character of crystallization, unless the heat raised so rap idly as not to permit complete fusion of the entire glaze mass. Inasmuch as each glaze used in the various blends had been rendered homogeneous by fritting, and the thick saggers and heavy brick work of the kiln necessarily made the raising of heat a comparatively slow process, it may be said that under these conditions the heat may be raised as rapidly as possible. The cooling. The question of cooling seems the all important one. Slow cooling was accomplished by two methods, first, by continuing the firing with a bare spot on the grate, and, second, by drawing the fire and sealing the kiln completely. The second method proved to be the bet ter, for the results by the first method were far from con sistent from burn to burn.
