Prehistoric pottery is the most abundant material discovered in archaeological sites and represents the main element of knowledge about human communities from the past. This study presents a model of interdisciplinary investigation of pottery through several types of analyses, enabling the scientific study of this category of artifacts. The analyses were performed on 11 ceramic fragments from the Middle Bronze Age settlement of Piatra Neamț–Lutărie, Eastern Romania, considering information about the color, production technique, type, size, functionality and category of the vessel, but also data related to ceramic paste inclusions. The samples were studied by optical microscopy (OM), scanning electron microscopy (SEM) coupled with energy-dispersive X-ray analysis (EDX) and micro-Fourier-transform infrared spectroscopy (µFTIR). The results obtained provide important information regarding pottery manufacturing technologies, such as sources of the raw materials and firing temperatures, and revealed the functionality of various vessel categories within a prehistoric settlement.

Wooden icons used in liturgical activities suffer a series of evolutionary deteriorations and degradations over time, due to improper storage and use conditions. The deterioration of the physical state of the structural-functional elements and degradation of the chemical nature of the components often lead old easel paintings to precarious preservation (almost close to pre-collapse), impossible to use or display as an artifact. In this study was included an old oil-painted icon on a carved linden wood support with fine gilded ornaments, which frames a central icon (“Coronation of Virgin Mary”) and a complex Menaion icon system with iconographic scenes. It was made by an anonymous author and dates back to the late 18th and early 19th centuries. As the icon has a special beauty and an ornamental and iconographic complexity, having a great heritage value, it required the elaboration of an optimal preservation–restoration protocol for the museum exhibition. Initially, the nature of the pictorial materials was determined, and their preservation state was evaluated using the OM, SEM-EDX, micro-FTIR methods, and CIE L*a*b* colorimetry and visible and UV reflectography were used in the evaluation of the wash test and in compatibility studies. Based on the data obtained, the optimal materials and procedures for structural reintegration were selected (including support fillings and filling of gaps), then chromatic reintegration and gilding, followed by final revarnishing, with or without patination additives.

This paper presents the study of three bronze socketed axes discovered in Neamţ County, Romania. The surface structures and those from the interface of the corrosion layer with the metal core of the basic alloy were analyzed, in order to elucidate the nature of the materials used and the manufacturing processes. The analyzes by optical microscopy (OM) and electron microscopy (SEM), coupled with X-ray spectrometry (EDX), revealed the type of their degradation during the depositional period, as a result of the processes of chemical alteration and physical damage. A series of metallurgical techniques used were also established, as well as the identification of some finishing and decoration processes that led to the establishment of the objects’ functionality.

By correlating the structural–functional dimensional data with a series of archaeometric and chemometric characteristics determined by dendrochronological analysis and by three instrumental techniques (Scanning Electronic Microscopy, coupled with Energy Dispersive X-ray, µ-FTIR Spectroscopy and Thermal Analysis in Dynamic Mode), a Stradivarius violin was authenticated as having been made by one of the two Stradivari sons (Francesco or Omobono) in 1723. It should be noted that the “petite” type violin, which comes from a private collection and was recently purchased on the open market, has the original label and is in a poor preservation state. There is only one revarnishing intervention on the violin, and it is older than 80 years. There have been several attempts at sampling (all of which are under 30 years old) for the wooden support and varnish (from the top cover of the resonance box), but the existence of some analysis results is unknown. The dimensional characteristics of the structural–functional components place the violin in “petite violins”, and it is one of the more than 40 still preserved as an authentic artifact.

Vessels with a special shape have always been a point of interest for pottery studies, especially from the perspective of the distinct functionality that these pots would have had. The ceramic typologies made for the miniature finds specific to the Middle Bronze Age in the Eastern Carpathian area include a series of such vessels attributed to the Costișa communities. Currently, the role of these pots is still under debate, being classified as ritual or special, which led to two case studies focused on investigating these miniatures. The analyzed vessels come from the Piatra Neamț—Bâtca Doamnei and Siliștea—Pe Cetățuie settlements (Neamț County), where these containers were discovered with traces of pigment or in association with colored minerals. These findings led to a series of questions related to their use, as it is known that in the Middle Bronze Age there are not many archaeological discoveries that explain the presence of pigments in the studied area. In this sense, multiplication of information was achieved by performing detailed analyses, such as optical microscopy (texture and surface details), colorimetry CIE L*a*b* (color investigation), SEM-EDX (elemental composition) and µ-FTIR (chemical compounds). The results of the interdisciplinary study led to new data on the nature of the pigment and the method of preparation, and also clues on the source of the raw material. Thus, these items illustrate the special use of miniature vessels and their probable functions.
