摘要:
Laboratory X-ray powder diffraction was used to investigate mineralogical compositions of green pigments labeled by suppliers as "green earths." It was found that glauconite and celadonite-minerals historically considered as the main ingredient of this pigment-were present only in Bohemian green earth, green earth from Thuringen (glauconite), and Bavarian green earth (celadonite). Other investigated pigments consist of mineralogical-component minerals with added synthetic organic colorants. The obtained results may be useful for scientists, restorers, and artists in proper choices of the pigments they use in their works. (C) 2010 International Centre for Diffraction Data.
