The study and conservation of a painting by Wasily Kandinsky, titled Spitz-Rund and dated to 1925, was carried out at the Centro per la Conservazione ed il Restauro dei Beni Culturali “La Venaria Reale” 2018 and 2021. This work, owned by the Galleria d'Arte Moderna e Contemporanea of Bergamo (GAMeC), was created with oil paints on cardboard, and later glued onto a wooden support. A first phase of the project entailed a thorough scientific investigation of the artist's materials and techniques by means of a multi-analytical approach, including both non-invasive and micro-invasive techniques. The present contribution discusses some of the most relevant results obtained from scientific analyses on Kandinsky's masterpiece. The painting stratigraphy and colour palette were investigated using multispectral imaging, spot XRF and in situ Raman analyses. Micro-samples were also taken and analysed with FTIR spectroscopy, Py-GC/MS, optical microscopy and SEM–EDX. Additional investigations using MA-XRF provided further insight into the distribution of various chemical elements, proving essential to deepen our knowledge of the painting and to integrate the information obtained from other analytical techniques. The study highlighted several similarities between Spitz-Rund and other Kandinsky's artworks and made it possible to gain a broader understanding of the artist's technique during the Bauhaus period (1922–1933).

探索瓦西里·康定斯基的调色板：《斯皮茨-伦德》案例研究 (1925)

瓦西里·康定斯基 (Wasily Kandinsky) 的一幅名为《斯皮兹伦德》(Spitz-Rund)的画作的研究和保存其历史可追溯至 1925 年，于 2018 年和 2021 年在“La Venaria Reale”保护中心进行。该作品由贝加莫现代艺术画廊 (GAMeC) 所有，创作于在纸板上涂上油画，然后粘在木支架上。该项目的第一阶段需要通过多种分析方法（包括非侵入性和微侵入性技术）对艺术家的材料和技术进行彻底的科学研究。本文讨论了对康定斯基的杰作进行科学分析所获得的一些最相关的结果。使用多光谱成像、点 XRF 和原位拉曼分析对绘画地层学和调色板进行了研究。还采集了微量样品并使用 FTIR 光谱进行分析，Py-GC/MS、光学显微镜和 SEM-EDX。使用 MA-XRF 进行的其他研究进一步深入了解了各种化学元素的分布，这对于加深我们对这幅画的了解以及整合从其他分析技术获得的信息至关重要。该研究强调了两者之间的一些相似之处斯皮茨-伦德和康定斯基的其他艺术作品，使人们能够更广泛地了解包豪斯时期（1922-1933）艺术家的技巧。
