[0016] like Figs. 1-3 As shown, the present invention A method for producing natural-colored ceramics, characterized by comprising the following steps: S1 is used to make the blank. The blank is made of conventional clay and then pressed with a hard object to create grooves on the surface of the blank.

[0017] S2 Apply base glaze. Apply base glaze to the surface of the body 61. Before the base glaze is completely dry, sprinkle granules on the surface of the body. After the base glaze dries, fix the granules 64 on the body. The granules 64 can be made by drying the same material as the base glaze.

[0018] S3 is a top glaze, which is applied to the outside of the body with the base glaze; the top glaze covers the base glaze and the particulate matter 61.

[0019] In S4 firing, the unglazed body is sent into the kiln for firing, and the unglazed body is fired into a porcelain body. The base glaze on the unglazed body 61 forms a base glaze layer 62 in the porcelain body, and the surface glaze on the unglazed body forms a surface glaze layer 63 in the porcelain body. The hardness of the base glaze layer 62 is greater than that of the surface glaze layer 63.

[0020] S5 grinding involves placing the fired porcelain blank into a grinding device and grinding the surface of the blank with grinding balls. The hardness of the grinding balls is greater than that of the surface glaze layer and less than that of the base glaze layer. Grinding is stopped after the surface glaze layer of the porcelain blank is partially ground off and the base glaze layer is exposed.

[0021] The grinding device includes a base 2, a vibratory plate 1, and a spraying device 4. The top of the vibratory plate 1 has an annular material trough 11, and a central column 12 is located in the middle of the material trough 11. A vibration source 4, which is a vibration motor, is located inside the central column 12 to drive the vibratory plate. Three spiral grooves 13 are arranged around the outer wall of the central column 12, extending upwards. The upper ends of the spiral grooves 13 extend to the top of the central column, forming a discharge port 131. Below the discharge port 131, a blade 14 is located on the upper part of the central column 12. One end of the blade 14 can be hinged to the central column 12, and the other end of the blade 14 extends outwards and downwards into the material trough 11. A recessed vein groove is located in the middle of the blade, extending from one end of the blade to the other. A drainage hole is located at the bottom of the material trough.

[0022] The bottom outer periphery of the vibratory plate 1 is provided with several springs 3 arranged in a circle, and the lower ends of the springs 3 are connected to the base 2. The base 2 includes an upper seat 22 and a lower seat 21. The lower seat 21 has an upwardly protruding column in the middle. The lower ends of the springs are connected to the lower seat. Several springs are distributed in a ring around the outer periphery of the column. The lower part of the upper seat 22 is movably mounted on the column. The top of the upper seat 22 is provided with a ball head. The bottom surface of the vibratory plate 1 has an inner cavity in the middle. The top of the inner cavity is provided with a hemispherical groove 15. The upper part of the upper seat 22 extends into the inner cavity, and the ball head 23 abuts against the hemispherical groove 15. The vibratory plate 1 can vibrate up and down with the upper seat relative to the lower seat, and can also rock around the ball head.

[0023] The spraying device includes a column, a rotating arm, and a spray frame 51. The spray frame is positioned above the vibrating plate and can spray liquid into the material tank. During the grinding step, the fired ceramic blank is placed into the material tank, and the spraying device sprays water into the material tank. The column is located on the side of the base, one end of the rotating arm is rotatably mounted on the column around a vertical axis, and the spray frame is located at the other end of the rotating arm. The spray frame is equipped with spray heads that can spray downwards. Rotating the rotating arm allows the spray frame to move in or out of the vibrating plate.

[0024] The finished product is obtained by cleaning the ground porcelain blank to obtain naturally colored ceramics.

[0025] This invention uses grinding balls to grind the outermost glaze layer of the porcelain blank to create a specific roughness, resulting in a soft, reflective surface. When the vibrating disc 1 of the grinding device vibrates, the grinding balls grind the surface of the porcelain. Grinding balls near the central column are conveyed upwards along the spiral groove 13 under vibration until they reach the discharge port 131. The grinding balls are then discharged from the discharge port 131 and conveyed outwards along the blades 14 to a position in the trough away from the central column, accelerating the flow of the grinding balls within the trough. The spray nozzles of the spraying device spray water into the trough 11 through gaps to wash the grinding balls. The vibrating disc vibrates up and down and oscillates back and forth, allowing the porcelain in the trough to be ground by a wider variety of grinding balls of different sizes, resulting in good grinding effect and high efficiency. Since the hardness of the grinding balls is lower than that of the base glaze layer, the grinding effect on the base glaze layer is not significant, allowing the base glaze layer to remain intact and form a waterproof layer. The porcelain grinding process is simple and controllable, and after grinding, the reflected light on the surface of the porcelain is a soft, natural-colored light.

[0026] The above description is merely a preferred embodiment of the present invention and does not limit the scope of the present invention. All equivalent changes and modifications made in accordance with the claims of the present invention should still fall within the scope of the present invention.
