It explores the ARCAer project which will address this set through its historical, stylistic and iconological study. It will include laboratory analysis of the materials and technologies associated with the production of the sculptures with the intend of establishing affinities and differences between the several objects, which may bring clarification about their origins, their ordering process and the conservation treatment of the set. It is intended to recover the works and relocate them in their original places, resuming an integrated discourse that was lost. Also, the project aims to reflect upon the human drive to preserve material memories, establishing parallels with our days

Pulsed laser induced breakdown spectroscopy (LIBS) and Raman spectroscopy were performed using a ... more Pulsed laser induced breakdown spectroscopy (LIBS) and Raman spectroscopy were performed using a novel laboratory setup employing the same Nd:YAG laser emission at 532 nm for the analysis of five commercially available pigments collectively known as "ultramarine blue", a sodium silicate material of either mineral origin or an artificially produced glass. LIBS and Raman spectroscopy have provided information regarding the elemental and molecular composition of the samples; additionally, an analytical protocol for the differentiation between natural (lapis lazuli) and artificial ultramarine blue pigments is proposed. In particular LIBS analysis has allowed the discrimination between pigments on the basis of peaks ascribed to calcium. The presence of calcite in the natural blue pigments has been confirmed following Raman spectroscopy in specific areas of the samples, and micro-Raman and optical microscopy have further corroborated the presence of calcite inclusions in the samples of natural origin. Finally multivariate analysis of Laser induced breakdown spectra using principal component analysis (PCA) further enhanced the differentiation between natural and artificial ultramarine blue pigments.
