The invention provides a preparing process of a blazer colored glaze product, and belongs to the field of glass preparing processes. The process is characterized in that the process includes steps of melting a crystal material into molten glass having a temperature of 1400-1450 DEG C, taking out the molten glass, blowing the molten glass into a glass bulb, cooling the glass bulb to 800-900 DEG C, then soaking the glass bulb into pigment molten paste having a temperature of 1380-1420 DEG C for color processing, covering the glass bulb after color processing with silver paper, dipping the glass bulb into powdered pigment having a temperature of 1000-1020 DEG C while melting the silver paper, dipping the product into room-temperature water, blowing to form a glass bulb, tempering the glass bulb, cooling the glass bulb to 700-800 DEG C, then soaking the glass bulb into the molten glass prepared from the crystal material again with the temperature of the molten glass being 1400-1450 DEG C, taking the glass bulb out, blowing, forming, and cooling a product. The process achieves a blazer existence on a glass product and ensures the yield, and the prepared colored glaze product has obvious blazer effects.
