| Abstract: | ATR-FTIR spectroscopy is used to analyze the interaction of yellow ochre with a binding medium (linseed oil) and other pigments (orpiment and azurite). Spectra of four different samples of ochre are compared. Variations in the IR spectra of ochre resulting from drying it on various substrates are detected. Changes in spectra of the linseed oil upon its drying are analyzed. |
