Cross-cultural transformation of Tang Dynasty porcelain stem cup: a quantitative typological analysis of design and social factors

Against the backdrop of cross-cultural design integration promoting global cultural exchange, this study delves into how social factors influenced the design translation of foreign artefacts within the local context of China. Focusing on the case of porcelain stem cups from the Tang Dynasty (618–907 AD), this research employs quantitative typological methods, combined with socio-historical literature and Pierre Bourdieu’s practice theory, to systematically analyse the profound transformations of this quintessential foreign artefact in its form, function, and symbolic meaning. The findings reveal that the localisation of the stem cup was not a simple stylistic imitation but a complex fusion driven by multiple social forces. First, the lifestyle shift from floor-sitting to elevated seating reshaped ergonomic demands, driving its form toward more functionally stable designs. Second, the material translation from metal to ceramic positioned porcelain as a new form of cultural capital, embodying the taste and status of the elite. A diachronic analysis uncovers a clear evolutionary path from early imitation to a mature, localized paradigm. At a deeper level, the stem cup’s tripartite form (foot, stem, body) achieved symbolic resonance with traditional Chinese architectural principles and the cosmological concept of “Heaven, Earth, and Human,” completing its cultural translation. Furthermore, a comparative analysis of the Xing, Changsha, Yue, and Qiong kilns reveals the differentiated design strategies adopted to meet the distinct demands of domestic, export, or tribute markets within their respective socio-economic fields. Ultimately, this research argues that the evolution of the Tang porcelain stem cup was a cultural process that comprehensively localized a foreign artefact from its form to its essence. The study provides a data-driven explanation for material culture change along the Silk Road, offering profound historical insights for contemporary cross-cultural design and the innovative development of cultural heritage.
