Abstract: | Glazed surfaces can be produced on the face of ware mode from practically any clay or shale having maturing temperature of cone 1 or more by coating the face of the ware with a slip containing sodium chloride. Various concentrations of salt in the slip have been used. Lower concentrations do not produce glazes but develop interesting surface and color effects. Metallic oxides may be used to produce variation in color of the glaze. This method shows promise as a means of securing salt glazes in kilns which have heretofore been considered impractical for salt-glazing purposes, although it has been developed only in the lahoratory stage at the present time. Sodium carbonate has also been used successfully. |
