Vis-NIR reflectance spectra of Huy pigments (PIG_0172_A): blocks, powders, plots and painted matters

Vis-NIR reflectance spectra of Huy pigments (PIG_0172_A) as 1 raw block and 1 sawn (2 faces each), as powders with several grain sizes (<50µm, <160 µm, 100-200µm, 200-400µm, >400µm) and several densities, as a polished plot, and a painted matter on limestone

本数据集包含编号为PIG_0172_A的Huy颜料（Huy pigments）的可见-近红外（Visible-Near Infrared）反射光谱，其样品形式涵盖：1块原生块料、1块锯切样品（每块样品含2个切面）；不同粒径（<50μm、<160μm、100~200μm、200~400μm、>400μm）与多种密度的粉末态样品；抛光片样品；以及石灰岩基底上的涂覆颜料样品。
