This work reports on recycling various amounts of inorganic wastes (scraps of glass packaging waste, key sawdust, copper slag, and pyrite ash) into artistic ceramic glazes. These waste materials were used in the range of 0.6–20% in artistic glaze compositions. Glazes were composed of a mixture of acidic (SiO2, B2O3), basic (Na2O, K2O, CaO, ZnO, PbO), and amphoteric (Al2O3, Cr2O3) oxides and formulated using the Seger method. These glaze compositions were applied over the surface of the porcelain body and fired at 1080 °C and characterized by field emission scanning electron microscope (FESEM) coupled with energy dispersive X-ray spectrometry (EDS). As a consequence, results showed that, different inorganic wastes could be used in artistic glaze compositions for the obtaining attractive colors and textures.
