PURPOSE: Crystalline glaze containing iron (Fe) is provided to form a unique pattern on the surface of ceramics by the iron components, using rusted tin, stones, and iron oxides in an optimum ratio. CONSTITUTION: Crystalline glaze contains 0.5-10 wt% of 1-100 um granules of rusted tin, 0.5-10 wt% of 50-200 mesh stones, 0.05-10 wt% of 1-100 um granules of iron oxides, 10-45 wt% of 50-200 mesh feldspar, 10-20 wt% of 1-100 um granules of zinc, 10-25 wt% of 50-200 mesh limestone, and 10-20 wt% of 50-200 mesh kaolin. The stones are one or more selected from hematite (Fe2O3), magnetite (Fe3O4), or Ilmenite. A plasticizing and cooling method of the crystalline glaze comprises the following steps: heating a crystalline glaze composition to 1,230-1,250°C, and maintaining the temperature for 30 minutes-1 hour; and cooling the heated crystalline glaze composition to 1,100-1,150°C and maintaining the temperature for 2-4 hours.
