Experiments are reported demonstrating the possibility of producing localized, definitely controlled effects of reduction, in oxidizing or neutral kiln atmospheres, through the use of glazes or slips of special composition. This control was obtained by two methods as follows: (1) by incorporating silicon carbide in the glaze batch and (2) by introducing silicon carbide into underglaze slips. In ordinary kiln atmospheres both methods produced satisfactory results in which predetermined areas of copper reds and copper blues or greens were developed on the same piece.
