Abstract
This study explores the development of a low-fire metallic luster glaze without employing traditional reduction firing techniques, utilizing locally sourced clays from Qena, Egypt. The research aimed to formulate an environmentally friendly and cost-effective glaze by harnessing the natural chemical composition of agricultural, marl, and Nile clays. Through three structured experimental phases, various combinations of fluxing agents (lead oxide and borax), metal oxides (MnO2, CuO, Cr2O3, AgNO3, CuCO3, Bi2O3), solvents (water- and oil-based), and glaze modifiers (potassium feldspar and wood ash) were systematically tested. The results revealed that manganese oxide, especially in combination with lead oxide, consistently produced a glassy metallic luster across all firing conditions and solvents. Copper oxide also generated significant luster effects, particularly when paired with borax and oil-based solvents. Other oxides showed limited or no effectiveness in luster formation. The incorporation of potassium feldspar and wood ash was found to enhance glaze uniformity and surface aesthetics. This research presents a viable alternative to reduction-based luster glaze methods by demonstrating that metallic luster can be achieved under oxidizing conditions using natural materials. The findings offer promising implications for sustainable ceramic production, particularly in regions with abundant local clays and limited industrial resources.
