A method for manufacturing sharp spine-shaped projections on ceramic includes forming projections by applying a first soil water on the outside of the half-dried ceramic, forming projection roots; and growing projections by applying a second soil water on a plurality of the projection roots fifty to one hundred times using the brush and letting the projections dry at 15˜20° C., and 60˜70% of relative humidity for 15˜25 minutes in the shade after the application. Bright and mysterious various ceramic patterns are achieved by controlling water content of a first soil water to control projections density, controlling the number of a second soil water applications to control projections' size, selecting the direction of applications to form projections bent toward various directions and mixing pigments with soil water at proper time with proper mixing ratios to form projections with various colors.
