• •It is proposed the industrial residues revalorization based on vitrification process.•It was prepared a glaze suspension from industrial residues.•It was designed a glass-ceramic glaze doubling the porcelain tiles properties. In this research a mixture of 90%wt of industrial residues (recycled soda-lime glass and ashes from a coal power thermal plant) have been vitrified for their use as “secondary raw material”. Then, a glaze suspension was prepared to be applied on the porcelain stoneware tile. The tested pieces have been fired by a conventional porcelain cycle at 1180 °C of maximum temperature. The XRD, XRF, SEM/EDS and the dilatometric analysis have been the instrumental techniques used to characterize the material. Finally, an ecological glass-ceramic glaze perfectly fitting on porcelain ceramic tile has been produced, exhibiting a unique phase, anorthite, which ensures a high flexural strength (around 96 MPa) and a significant Vickers microhardness of 250 GPa, improving the mechanical properties of a conventional the porcelain ceramic tile.
