A violet sand earthenware glazing method includes the following steps: a), drying a violet sand earthenware blank in the shade for 3-8 days; b), biscuiting the violet sand earthenware blank in a kiln, increasing the temperature by 0.5-1 DEG C each minute before the temperature reaches 100 DEG C, increasing the temperature by 1-2 DEG C each minute until the temperature reaches 500 DEG C after the temperature reaches 100 DEG C, increasing the temperature by 0.8-1.2 DEG C each minute until the temperature reaches a specific value between 600 DEG C and 800 DEG C after the temperature reaches 500 DEG C, and drawing the blank out after continuing firing the blank for 3-4 hours; c), applying an interlayer glaze on the surface of the violet sand earthenware blank according to a glaze immersion method, firing the blank at the temperature of 1150-1250 DEG C for 5-8 hours in the kiln after drying in the shade, insulating the blank for 0-10 minutes, lowering the temperature to 270-300 DEG C and drawing the blank out of the kiln; d), spraying a medium-temperature glaze onto the cooled interlayer surface, putting the blank into the kiln, firing the blank at the temperature of 1100-1120 DEG C for 2-3 hours and cooling the kiln.
