6 Claims

1. A method for manufacturing a ceramic tile decorated with a dry particle ink, wherein the method comprises

A: glazing a surface of a green body with a ground coat;

B: maintaining a temperature of the green body at 40-60° C. after the green body is glazed with the ground coat of step A; then, decorating a surface of the ground coat of the green body to form a pattern;

C: performing a first drying on the green body after the green body is decorated with the pattern of step B;

D: embellishing the green body with dry particles by spreading the dry particle ink on the surface of the green body after the first drying of step C; then, performing a second drying;

E: spraying a protective glaze on the surface of the green body after the second drying of step D; and

F: firing the green body after the green body is sprayed with the protective glaze of step E to produce the ceramic tile, the ceramic tile is decorated with the dry particles and has a three-dimensional pattern,

wherein in step D, the dry particle ink comprises the following raw materials in parts by weight:
