Glaze is a glassy layer used to cover surfaces of different ceramic products. It gives ceramic surface hardness and high resistance to chemical and abrasion which contributes to enhancing the chemical and physical properties in addition to the aesthetics of the ceramic products. Production process of glaze is complex and expensive, as it requires accurate compositions of different materials most of which are expensive. herefore, the main aim of this study is to develop a transparent ceramic glaze from the Local clays of Qena Governorate. Three types of local clays used in this study were “Taffla” marl clay, “Hieba” Flood Clay, and Nile clay. The production processes were conducted at different combustion temperatures of 1000, 1050, and 1100°C using borax as alkaline fluxing agents at different ratios of 50%, 60%, and 70%. The glaze is produced only from the clay and fluxing agent without the need to add any former or bonding refractory materials which are common in traditional methods of glaze production. The required tests were carried out for clay and glaze to determine their different characteristics. Results showed that among the three products, the best results were achieved at combustion temperature of 1050°C and the highest alkaline fluxing agent ratio of 70%. Moreover, the obtained results demonstrated that the possibility of the production of transparent ceramic glaze directly from special types of clay without adding any other material which minimize effort, time glaze
