Abstract

The identification of ceramic forming techniques poses challenges, particularly when different primary and secondary forming techniques are combined, or when specific surface treatments obscure potential diagnostic features. As emphasized in the existing literature, a comprehensive approach should consider all potential sources of information. In this study, we employed a combination of macroscopic observations and X-ray microCT analysis on experimental cups reproduced using the complex technology attested in Middle Bronze Age Crete, i.e. a combination of hand-building technique and potter's wheel. Our investigation focuses on the potential of microCT scanning in unveiling forming techniques in wheel-thrown and wheel-fashioned ceramics. Our results indicate that integrating the visualization of 3D thickness variation in vessel walls, quantification of 2D wall thickness distribution in longitudinal virtual slices, identification of possible structural joints in virtual sections, and evaluation of voids orientation with traditional macroscopic analysis generally allows for the recognition of primary forming techniques and the reconstruction of complex ceramic technological processes.

用 X 射线显微 CT 揭示轮制陶瓷的初级成型技术
陶瓷成型技术的鉴定是一项挑战,特别是当不同的主要和次要成型技术结合在一起时,或者当特定的表面处理掩盖了潜在的诊断特征时。正如现有文献所强调的,综合方法应考虑所有潜在的信息来源。在这项研究中,我们采用了宏观观察和 X 射线显微 CT 分析相结合的方法,对使用克里特岛青铜时代中期的复杂技术(即手工制造技术和陶轮相结合)复制的实验杯进行了分析。我们的研究重点是显微 CT 扫描在揭示轮抛和轮制陶瓷成型技术方面的潜力。我们的研究结果表明,将器皿壁三维厚度变化的可视化、纵向虚拟切片中二维壁厚分布的量化、虚拟切片中可能存在的结构接缝的识别以及空隙方位的评估与传统的宏观分析相结合,一般可以识别主要的成型技术并重建复杂的陶瓷工艺过程。

期刊介绍: The Journal of Archaeological Science is aimed at archaeologists and scientists with particular interests in advancing the development and application of scientific techniques and methodologies to all areas of archaeology. This established monthly journal publishes focus articles, original research papers and major review articles, of wide archaeological significance. The journal provides an international forum for archaeologists and scientists from widely different scientific backgrounds who share a common interest in developing and applying scientific methods to inform major debates through improving the quality and reliability of scientific information derived from archaeological research.
