New Criteria for Classification of and Differenciation between Clay and Iron Oxide Pigments of Various Origins
Original language description
In this paper we have verified that mineralogical composition of clay minerals in earthy pigments is a suitable tool for more detailed specification of material provenance and, in the case of ground layers, also the provenance of the artwork as such. Forthe purposes of statistical comparison we evaluated elemental composition of earthy grounds on 70 paintings from the 16th ? 18th centuries from Czech collections. We performed detailed mineralogical analyses for a selected representative number of grounds ? on 35 samples in total. We discerned 6 types of material in total ? 2 types of boles, 3 types of other earths, and one type representing iron-rich red from oxidized zones of hydrothermal ore deposits. We were able to distinguish between earthy pigments of Central European origin (coming from Czech and Bavarian locations) and those coming from North-Italian sources.
