<p>This study presents a novel approach to the sustainable reuse of mineral waste in ceramic glaze production from Shoushan stone processing residues. The research highlights their synergistic role in regulating the coloring mechanism and optimizing glaze layer properties. By using single-factor experiments, we examined the dependence of ceramic performance on Shoushan stone content. Its influence on glaze microstructure, copper ion valence states, and chromatic parameters was analyzed using x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDS), and x-ray photoelectron spectroscopy (XPS) techniques. The incorporation of 10 wt.% Shoushan stone significantly enhanced glaze density and gloss and stabilized the presence of Cu²⁺ ions, improving the purity and stability of the blue coloration. Physicochemical testing confirmed that the glaze layer exhibits high thermal shock resistance, mechanical strength, and environmental safety. These findings demonstrate that, along with solid waste valorization, rational reuse of Shoushan stone waste improves the structural and optical performance of copper-based blue glazes, underscoring their promising potential for sustainable ceramic applications.</p>
