Innovations in Enamelled Porcelain Materials and Techniques from the Perspective of Cultural Integration in Southeast Chongqing

Enamelled porcelain represents a distinctive category of overglaze decoration that emerged from the fusion of Chinese porcelain body techniques with European low-fusing enamel pigments. This study provides a comprehensive review of the historical evolution of enamelled porcelain and examines its unique artistic language. Particular emphasis is placed on recent innovations in lead-free boron–lithium frit formulations, low-temperature firing processes, and contemporary painting techniques. Through comparative material analysis and firing experiments, the study verifies the energy efficiency, environmental sustainability, and enhanced visual quality of these updated methods. The objective is to offer both technical support and theoretical insights for the sustainable industrial development and cultural revitalization of enamelled porcelain in the contemporary context. Moreover, drawing on traditional ceramic and decorative arts practices in Southeast Chongqing, the paper explores the potential for integrating enamelled porcelain into intangible cultural heritage revitalization and creative cultural industries. This research highlights the aesthetic expression and cultural reinterpretation of this traditional craft from a design-oriented perspective.
