The invention relates to a preparation method of black photon glaze. The preparation method includes the steps that kaolin, quartz, SrCO3, TiO2, limestone, BaCO3, sodaclase, ZnO, Pb3O4 and spodumene powder are adopted as raw materials, burdening, ball-milling, screening, decaying, drying, glazing, sintering and cooling are carried out, and then the product is obtained. The black photon glaze prepared with the method with a solid-phase sintering method can absorb or consume incident light of almost all wavebands, thus, energy emitted to a blank structure is reduced, and the temperature of a blank is remarkably reduced. The method is simple in process, addition of heavy metal elements in tinting pigments is reduced, resource saving and environmental protection are benefited, the cost is low,large-scale production is easy, and therefore the preparation method has broad market prospects.
