Chrysotile, a variety of serpentine mineral was investigated by vibrational and magnetic resonance spectroscopic methods. The SEM photograph of the sample shows that chrysotile is made up of thin and flexible fibrils, classified as asbestos. The calculated lattice parameters were a=5.1961±0.0053Å, b=9.2365±0.0107Å, c=14.6208±0.0039Å; β=90.15±0.19°; Z=4, with space group C2/m. Three bands observed...
The results of FT-IR, SEM–EDAX and EPR investigations of some binders used in classical paintings and artificial aged binders, i.e. linseed oil, hen yolk and linseed oil/hen yolk are presented and discussed. Carbon dioxide, sulfur dioxide as well as nitrogen oxides were used as aging agents. Accordingly, the FT-IR spectra of all binders showed a set of characteristic modifications. This makes it possible...
