A multi-analytical approach was used to study the constituent materials, manufacturing technique, and state of conservation of a contemporary sculpture. This sculpture, entitled Nuredduna, was created by Aligi Sassu in 1995 and is located in the "Bellariva garden" in Florence (Italy). Fourier transform infrared spectroscopy (FT-IR), optical and electronic microscopy (OM and SEM-EDS), X-ray diffraction (XRD), and portable X-ray fluorescence (XRF) highlighted the multi-layered structure of the statue: fiberglass and an overlay of different layers (gel coat) applied with an unsaturated polyester resin added with aggregate materials and bromine compounds. A top-coat in acrylic black varnish, used as a finish, was also found. The combination of these materials with their different compositions, environmental impact, and even vandalism have negatively affected the state of conservation of Nuredduna, causing the loss of strata in its lower parts (legs and feet).
采用多分析方法研究一件当代雕塑的构成材料、制造工艺和保存状况。这件名为《努雷杜纳》的雕塑由阿利吉·萨苏于1995年创作，位于意大利佛罗伦萨的“贝莱里瓦花园”。傅里叶变换红外光谱（FT-IR）、光学和电子显微镜（OM和SEM-EDS）、X射线衍射（XRD）以及便携式X射线荧光光谱（XRF）揭示了这座雕像的多层结构：玻璃纤维以及涂覆有添加了骨料和溴化合物的不饱和聚酯树脂的不同层（胶衣）。还发现了一层用作表面处理的丙烯酸黑色清漆。这些材料因其不同的成分、环境影响甚至故意破坏行为的综合作用，对《努雷杜纳》的保存状况产生了负面影响，导致其下部（腿部和脚部）的层位缺失。
