Ceramic color compositions which are moisture or steam settable are described. The compositions are formulated from a dispersion of ceramic pigments or glass colors in certain moisture or steam set type vehicles and can be applied to green or bisque ceramic ware using standard decorating techniques and then set to a coating by exposure to moisture or steam. Over-glazing of the coating provides decoratively glazed ware of excellent quality and durability.
