Vis-NIR reflectance spectra of Fontenaille pigments (PIG-0175-2016 + PIG-0218-2019): raw block, powders with different grain sizes and painted matter

Vis-NIR reflectance spectra of Fontenaille pigments (PIG-0175-2016) as powders with grain sizes < 160 µm and > 160 µm at 2 densities (1.46/1.48 & 1.64 g/cm3), and as a sawn block (PIG-0218-2019), and a painted matter on limestone

本数据集收录丰特奈颜料（Fontenaille pigments，编号PIG-0175-2016）的可见-近红外（Visible-Near Infrared, Vis-NIR）反射光谱数据，样品包含三种形态：一是粉末样品，分为粒径小于160微米与大于160微米两种组别，且分别以1.46/1.48和1.64 g/cm³两种密度制备；二是锯切块体样品（编号PIG-0218-2019）；三是涂覆于石灰岩基材表面的涂装试样。
