The invention discloses a ceramic self-cleaning glaze. A ground glaze consists of 33 parts of an ultrafine quartz powder, 20 parts of feldspar, 10 parts of wollastonite, 5.5 parts of calcite, 4 parts of dolomite, 3.5 parts of bahrain soil, 6.5 parts of a calcined alumina powder, 2 parts of calcined zinc oxide, 4.5 parts of frit and 13 parts of an ultrafine zirconium silicate powder; an overglaze consists of the components in parts by weight; 38 parts of the ultrafine quartz powder, 24 parts of feldspar, 13 parts of wollastonite, 4 parts of calcite, 3 parts of dolomite, 4.5 parts of bahrain soil, 7 parts of a calcined alumina powder, 1.5 parts of calcined zinc oxide and 4.5 parts of frit; the particle size of the ground glaze is 1-10 microns, and the ground glaze is 0.8-1.2mm in thickness; the particle size of the overglaze is not greater than 10 microns, and the overglaze is 0.2-0.3mm thick; the ground glaze and the overglaze are calcined independently; the start temperature is 145 DEG C, the highest temperature is 1,298 DEG C, and the glazes are cooled to 70-80 DEG C; the calcining time is 12-22 hours. The number of needle holes and the number of cracks on the surface of the ground glaze are small, so that a product is uniform in texture, the surface is fine and bright, and dirt is unlikely to attach.
