The invention discloses crackle glaze and a manufacturing process. The crackle glaze is composed of a transparent glaze material and a high-expansion glaze material according to a mass percentage. The transparent glaze material and the high-expansion glaze material are composed of silicon dioxide, aluminum oxide, potassium feldspar, albite, calcium carbonate, borax and barium carbonate of different mass percents. The raw materials are evenly mixed in proportion, the mixture and water are mixed in proportion, a crackle glaze material is obtained after ball milling and sieving, the surface of a ceramic green body is coated with the crackle glaze material and then the ceramic green body is sent into a heating-up furnace to be fired, a semi-finished product with a crackle cracked glaze effect is obtained after drawing and cooling, and cracks on the outer surface of the semi-finished product are colored. The crackle glaze is simple in composition and rational in formula, the glaze effect of the manufactured crackle glaze is stable, the crack effect is good, and the crackle glaze is more uniform and attractive. The firing time in the manufacturing process is short, the firing temperature is low, so that the energy consumption is reduced, the crackle glaze saves energy and is environmentally friendly, and the production cost is reduced.
