"artists' pigments; celadonite; ferruginous smectite"@en . "A collection of green earths belonging to traditional artists' pigments was examined in terms of mineralogy and provenance. The studied specimens included both mineralogical reference compounds and selected commercially available artists' pigments, and contained green micas (glauconite or celadonite), chlorite, or smectite as pigmenting agents. The samples were examined by X-ray diffraction, Mossbauer spectroscopy, infrared (IR) spectroscopy, ultraviolet-visible (UV-Vis)-near-IR diffuse-reflectance spectroscopy and voltammetry of microparticles. Particular attention was paid to the Kadan green earth, mined until the 20(th) century in the West Bohemia deposit. The Greene-Kelly charge-reduction test, detailed description of non-basal diffraction patterns and characteristic vibrations in the mid-IR spectra were used to classify the major pigmenting agent of the Kadan green earth as ferruginous smectite with separately diffracting saponite-like clusters. The smectite contains similar to..."@en . "Green earth pigment from the Kadan region, Czech Republic: Use of rare Fe-RICH smectite" . . . "RIV/61388980:_____/04:00106545" . "6" . .
