A method of modifying glass frit involves treating the frit with a grain-boundary-healing compound. The method increases transmission and clarity, and reduces haze of a fired enamel coating made from such modified glass frit as compared to a coating not made from such modified glass frit. The grain-boundary-healing compound influences the chemistry at the grain boundaries to prevent haze. The compound burns out to yield a fluxing material that dissolves alkaline carbonates or bicarbonates on the surface of the glass frit. The dissolved species are incorporated into the enamel coating, thereby promoting the fusion of the glass frit and reducing the amount of haze in the enamel coating. The additives also function to prevent the formation of seed crystals on the surface of the glass frit that may inhibit the fusion of the glass frit.

A preparation method includes the following steps: Step (1): pressing and then drying body powder to form a green brick; Step (2): applying a ground coat on the surface of the green brick; Step (3): inkjet-printing a pattern on the surface of the green brick having the ground coat, and applying an isolation glaze; Step (4): applying a fully polished glaze on the surface of the green brick having the isolation glaze; and Step (5): drying, firing, and polishing the green brick having the fully polished glaze to obtain a hard wear-resistant polished glazed ceramic tile. The phase composition of the fired fully polished glaze is as follows: 10 to 20 percent by weight of corundum, 20 to 30 percent by weight of hyalophane, 0.5 to 1.0 percent by weight of hematite, and 50 to 68 percent by weight of amorphous phase.
