Pigment identification by spectroscopic means: an arts/science interface

Pigment identification on manuscripts, paintings, ceramics and papyri is critical in finding solutions to problems of restoration, conservation, dating and authentication in the art world. The techniques (molecular and elemental) used for these purposes are reviewed and compared, particular attention being given to Raman microscopy and laser-induced break-down spectroscopy. These give excellent results in respect of reproducibility, sensitivity, non-destructiveness, immunity to interference from adjacent materials, and depth-profile analysis. New advances in optics provide powerful and long needed links for Arts- and Science-based projects. To cite this article: R.J.H. Clark, C R.
