The invention discloses a softly-polished metallic brick and a preparation method thereof. The softly-polished metallic brick comprises a green brick, cover glaze and fancy glaze, wherein the fancy glaze comprises the following components in percent by mass: 92%-100% of basic fancy glaze and 0%-8% of colored oxide. The preparation method of the softly-polished metallic brick comprises the following steps of: (1) pressing powdery materials into the green brick, drying the green brick at a temperature of 150 DEG C for 1-1.5 hours; (2) sweeping the surface of the green brick, spraying 10-12g of water on the surface of the green brick to wet the surface of the green brick; (3) spraying the cover glaze on the green brick; (4) using a wire mesh with 140 meshes to print the fancy glaze on the surface of the green brick; (5) drying for 5-10 minutes at a temperature of 150 DEG C; (6) placing the green brick in the step (5) into a kiln to fire for 40-60 minutes at a temperature of 1160-1190 DEGC; (7) carrying out fine polishing and edge grinding on a fired ceramic tile to obtain the softly-polished metallic brick. The softly-polished metallic brick obtained by the application is excellent in property, rich in color and high in glossiness, and simultaneously has polishing texture of a polished brick and metallic color of a metal-imitating brick.
