The invention discloses a novel colored glaze manufacturing process comprising the following steps that (1) a silicone mold is made, specifically, silicone is evenly smeared on the surface of a mold, and after the silicone is solidified and the silicone mold is formed, gypsum is still needed for fixation; (2) wax mold filling is conducted, specifically, wax slurry is prepared, and hot-melted wax is poured into a silicone female mold; (3) the wax mold is detached; (4) the wax mold is trimmed, specifically, cold cutting is liable to make the wax mold shrink and deform, and the mold line trace left during mold detaching is eliminated; (5) a gypsum mold is made; (6) steam dewaxing is conducted, specifically, the whole wax-containing gypsum is put into a dewaxing machine and is heated by steam for 20-30 minutes, and after dewaxing, a fire-resistant gypsum female mold is obtained; (7) raw materials are selected, specifically, the distribution positions of color lumps are arranged; (8) the color lumps are put into a furnace, and sintering is conducted; (9) the gypsum mold is detached; (10) cutting and repair are conducted; (11) fine grinding is conducted for smoothness, specifically, a sprue gate of crystal glass is ground to be smooth through grinding sand; and (12) cold working and fine repair are conducted. The colored glaze manufacturing process provided by the invention is simple, products are not liable to damage, and preparation is safer and more reliable.
