摘要

渗色现象是瓷器装饰过程中应用含钴颜料的一个长期而普遍的问题,促使不同文明发展出各种应对策略来缓解这一问题。在本研究中,我们挑战了有关成分和粘度在决定青花器皿渗色效果中的作用的主流假设,提出了一个新颖的物理模型,将其定义为发生在玻璃硅酸盐内部的扩散过程,其严重程度可以用扩散距离来定性表示。借鉴现象学菲克定律和微观扩散机制,我们首次定量讨论了影响扩散行为的主要物理参数,明确了钴离子的扩散与介质粘度无关。此外,我们还对比了有出血效应和无出血效应的蓝色脱色剂的微观结构特征,发现国内的钴颗粒都被阳起石晶体包裹,作为钝化壳阻碍了钴颗粒的溶解。重要的是,我们的重新诠释对陶瓷中与钴颜料相关的出血效应具有更广泛的考古学意义,阐明了不同环境和文化背景下应对实践的历史轨迹以及资源形式、艺术表现和技术进步之间的多方面相互作用。总之,这些对出血效应的反应体现了技术演变的复杂性,突出了技术不仅仅是技术知识的延伸,也是一种与当地环境密切相关的社会建设形式。这种全面的理解有助于我们了解陶瓷的历史叙事和古代社会人类智慧的多样性,并对当代颜料制造产生潜在的影响。

Revisiting the bleeding effect in historical cobalt porcelain pigments: Mechanism, influence and technical responses

The bleeding phenomenon, a persistent and widespread issue in the application of cobalt-bearing pigment during porcelain decoration, has spurred different civilisations to develop various response strategies to alleviate this problem. In this study, we challenge the prevailing hypotheses concerning the role of composition and viscosity in determining the bleeding effect on blue-and-white wares, proposing a novel physical model framing it as a diffusion process that occurs within vitreous silicate, where the severity can be qualitatively expressed using the diffusion distance. Drawing upon the phenomenological Fick's law and microscopic diffusion mechanism, we quantitatively discuss the primary physical parameters that influence the diffusion behaviour for the first time, clarifying that the diffusion of cobalt ions is not related to the medium viscosity. Moreover, compared with the microstructural features of blue decors with and without the bleeding effect, we reveal that domestic cobalt particles are all encapsulated by anorthite crystals, acting as a passivation shell to hinder the dissolution of cobalt particles. Significantly, our reinterpretation has broader archaeological implications for the bleeding effect associated with cobalt pigment in ceramics, elucidating the historical trajectories of responsive practices and the multifaceted interplay between resource form, artistic expression and technological advancement across varying environmental and cultural contexts. Overall, these responses to the bleeding effect exemplify the complexities of technological evolution, highlighting that technology is not merely an extension of technical knowledge but also functions as a form of social construction deeply intertwined with its local context. This comprehensive understanding contributes to our understanding of historical narratives in ceramics and the diversity of human ingenuity in ancient societies, with potential implications for contemporary pigment manufacture.
