Abstract
Over the last years, the documentation of Heritage has been increasingly enriched with new forms of data representation and contents deriving from technological applications on artifacts and the progress of computer graphics: if, on the one hand, 3D survey has become an effective tool supplementing and supporting traditional study activities, as it can generate accurate and high-resolution digital models (available especially when physical access to materials is not possible, but also for enhancement or to formulate hypothetic reconstruction), on the other, archaeometry investigations can provide all that information (about composition, firing temperature of clay, etc.) that autopsy, comparison, formal, contextual, or bibliographic analysis cannot do on their own. This paper aims to show the potentialities of combined use of these non-destructive and non-contact approaches on the archaeological artifacts preserved at the Regional Museum of Lipari "L. Bernabò Brea" for the analysis, diagnostic, fruition, and forthcoming restoration purposes. Different methodologies, such as laser-based surveying, sfm digital photogrammetry, and Raman spectroscopy have been, respectively, adopted and combined to get reconstruction and characterize several clay masks and two figured calyx-kraters. The latter technique, in particular, has proved to be useful in compositional analysis of dyes and pigments contained in the clay.

Summary
The Regional Archaeological Museum of Lipari “L. Bernabò Brea” is located upon the rock of the “Castle”, an imposing dome of volcanic formation with characteristics of the natural fortress. The classic section of the itinerary exhibits a large collection of clay masks and statuettes, found during archaeological excavations, that are one of the most distinctive material evidences of Greek civilization of Lipára [1]: most of them come from funerary equipment of the tombs found at “Contrada Diana” or from votive “pits” or “dumps” located in sanctuary and the areas of necropolis, few others come from domestic and worship contexts placed in urban and peri-urban areas [2]. The whole collection comprehends 150 specimens exhibited and more than 800 fragmentary pieces stored in the Museum’s warehouses: their dimensions range from 6 to 25 cm of height, with some exceptions reaching 30 cm. The color, when preserved, is placed before cooking: on the smaller pieces, it is attested, especially in the hair; on the bigger ones, it connotes the surfaces
