The invention discloses a firing process for color-painted colored glaze. The firing process comprises the following concrete steps: subjecting the surface of colored glaze to preheating treatment, wherein the preheating temperature is 180 to 220 DEG C; painting color patterns on the preheated surface of the colored glaze with pigments; then placing the colored glaze into a firing kiln and carrying out firing treatment, wherein the firing temperature is 675 to 725 DEG C, and the firing time is 2 to 3 hours; and after cooling of the kiln for 72 hours or above, taking the colored glaze out of the kiln. Thus, the firing process provided by the invention can improve the fastness of the color-painted layer on the surface of the prepared colored glaze, so longer service life is achieved.
