The invention discloses a self-cleaning glaze and an application thereof as well as a ceramic sanitary ware. The self-cleaning glaze comprises the following components according to weight percentage: 15-26% of potash feldspar, 11-21% of albite, 5-13% of kaolin, 7-17% of calcite, 26-36% of quartz, 1-5% of barium carbonate, 2-5% of zinc oxide, and 3-9% of dolomite. The surface of a self-cleaning glaze layer takes on a beautiful snow-shaped decorative pattern and has smooth hand feeling. Marks of a pencil left on the surface of the self-cleaning glaze can be erased lightly while the opacified glaze leaves marks, so that the self-cleaning glaze has very strong dirt resistance unmatched by traditional opacified glaze, furthermore, the scratches are not left on the surface of the self-cleaning glaze layer when the surface is curved by the pencil, so that the self-cleaning glaze layer has high hardness and is wear resistant.
