Abstract

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.
