This represents a study of the effects of the seven common coloring oxides when introduced in a typical zinc silicate or willemite crystalline glaze. All the possible two‐and three‐color combinations for each colorant with a moderate color concentration and another similar series for strong color concentrations were investigated. A new method by which fritting the glaze is obviated through the use of sodium silicate is described. The soluble sodium content is introduced by sodium silicate rather than by a frit. Color absorption by the crystal was found to be most pronounced in the case of cobalt, decreasing in order with copper, manganese, iron, nickel, uranium and little, if any, absorption of chromium. Description of color effects of most of these would be inadequate.
