The invention discloses a series of multi-layered dappled color changing glaze. The color changing glaze is composed of bottom glaze, middle glaze and surface glaze. The bottom glaze comprises: 15-20parts of medium temperature 1# lead-free frit, 15-20 parts of nepheline syenite, 35-40 parts of medium temperature 2# lead-free frit, 5-10 parts of quartz, 5 parts of calcium carbonate, 3 parts of barium carbonate, 10 parts of kaolin, and 3-6 parts of a coloring oxide or lead-free ceramic coloring material. The middle glaze comprises 40-45 parts of nepheline syenite, 15-20 parts of medium temperature 1# lead-free frit, 10 parts of calcined talcum powder, 8-10 parts of quartz, 15 parts of calcium carbonate, 7 parts of calcined zinc oxide, 5 parts of kaolin and 3-12 parts of a coloring oxide orlead-free ceramic coloring material. The surface glaze comprises 20-25 parts of nepheline syenite, 10-15 parts of boron silicate, 10-15 parts of low temperature lead-free frit, 8-10 parts of quartz, 15 parts of calcium carbonate, 3 parts of barium carbonate, 7 parts of calcined zinc oxide, 7 parts of glass powder, 10 parts of kaolin and 3-5 parts of vanadium pentoxide. A preparation method comprises preparation of three layers of glaze, glazing and firing. The product patterns have three-dimensional aesthetic feeling.
