Abstract
High-resolution X-ray radiography using the twinned orthogonal adjustable tomograph device reveal new insights into four baroque oil paintings by Moravian masters Jan Kryštof Handke and Gabriel Müller. With pixel sizes as small as 50-88 μm, this technique visualized hidden features-such as overpainted figures, signatures, and past restorations-across large canvases (up to 1100 mm × 900 mm). Key findings include the discovery of a concealed St. Joseph figure in Handke's Madonna and Child (1753), confirming his authorship, and a signature in Müller's Maria Antonia of Questenberg, affirming its attribution. These results enhance one's understanding of the paintings' preservation state, past interventions, and artistic techniques, demonstrating the value of advanced radiography in art conservation.
使用双正交可调断层摄影设备的高分辨率x射线摄影揭示了摩拉维亚大师Jan Kryštof Handke和Gabriel m ller的四幅巴洛克式油画的新见解。该技术的像素尺寸小至50-88 μm，可以在大型画布（高达1100 mm × 900 mm）上显示隐藏的特征，如过度绘制的人物、签名和过去的修复。主要的发现包括在汉德克的《圣母与儿童》（1753）中发现了一个隐藏的圣约瑟夫形象，证实了他的作者身份，以及在米勒的《奎斯滕贝格的玛丽亚·安东尼娅》中发现了一个签名，确认了它的归属。这些结果增强了人们对绘画的保存状态，过去的干预和艺术技术的理解，展示了先进的放射摄影在艺术保护中的价值。
期刊介绍：
ChemPlusChem is a peer-reviewed, general chemistry journal that brings readers the very best in multidisciplinary research centering on chemistry. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies.
Fully comprehensive in its scope, ChemPlusChem publishes articles covering new results from at least two different aspects (subfields) of chemistry or one of chemistry and one of another scientific discipline (one chemistry topic plus another one, hence the title ChemPlusChem). All suitable submissions undergo balanced peer review by experts in the field to ensure the highest quality, originality, relevance, significance, and validity.
