Abstract
A preparation method includes: pressing and forming a ceramic base material to obtain a green body of a ceramic plate; applying a ground glaze on the surface of the green body to cover the base color and defects of the green body; applying a cover glaze on the surface of the green body after applying the ground glaze, wherein the cover glaze contains 0.2 wt % to 0.7 wt % of coloring metal oxide to make the coloring bright; roller-printing patterns on the surface of the green body after applying the cover glaze to produce a flowing cloud effect; and drying the green body with the roller-printed patterns and firing in a kiln. The present invention uses roller printing to print the patterns of cloud effect on the surface of the cover glaze, which form a sharp contrast with the color of the cover glaze, producing a better visually distinct effect.
