Gli obiettivi principali delle analisi sono l'approfondimento delle conoscenze relative alla presenza di materiale ceramico importato e/o prodotto in loco, e la caratterizzazione della tecnologia di produzione. Le indagini preliminari sui 18 campioni selezionati hanno evidenziato una discreta omogeneità di composizione chimica degli impasti, cui si accompagna una certa eterogeneità micro-strutturale (dimensioni e forma dei vacuoli, presenza di inclusioni grossolane). Saranno condotte ulteriori indagini volte alla caratterizzazione dei sedimenti argillosi locali, oltre ad analisi più approfondite tese, ad esempio, ad identificare l'origine dei pori quadrangolari osservati in molti campioni.

It belongs to different cultures, and in this paper a comparison among three of them is made: Vinča, Lumea Nouă and Foeni. An analogous number of samples has been selected for each of the three cultures, together with some clay samples collected in the Alba Iulia settlement area. The samples have been analysed by means of XRF, XRPD, and in thin section. Significant differences among the three cultures are only related to the alkalis contents. The Lumea Nouă pottery has higher potassium contents and contains microfossils, while the Foeni pottery differs to each other for the higher sodium contents. A clear correspondence between pottery and clays has not been found, so that we hypothesize that not all the pottery is local or, more probable, that a geological gradual variation in local clay deposits existed.

One of them, placed outside in the Bucci park, showed a lot of fractures, lacunas and biological decay. Therefore, a diagnostic study, a preliminary in situ restoration and a monitoring for over two years were carried out in order to verify the stability of the work.

The aim of the research was to complete the characterization of this type of historical porcelain, after the previous publication of data related to the body. The glazes were analyzed in thin section, in order to see the number of glaze layers, and by SEM/EDS for the determination of their chemical composition. All the glazes, both colored and uncolored, are of lead-alkaline type with a composition very similar to that of the glazes for the known production of majolica artifacts. They were fired at about 1000 °C or less, so that their application was done by brushing when the porcelain body, previously fired at about 1200 °C, was non porous. The chemical composition of the glazes permitted to define the raw materials used for obtaining them, and to calculate an approximate formulation of the batch. The raw materials are the same for all types of glaze, but their proportions can be significantly different, especially for lead oxide and sodium chloride.

The main objectives of this study was to distinguish local and imported productions. To this purpose both ceramics and local clay raw materials were taken into consideration. The following investigation techniques were used: optical microscopy, x-ray diffractometry, x-ray fluorescence spectrometry, thermal analyses, scanning electron microscopy, granulometric analyses. Petrographic and chemical analyses pointed out the existence of three different types bodies, among representative of the local production. The comparison between the results relative to ceramics and raw materials allowed confirming this hypothesis. The local raw material used is a messinian clayey silt, which is known in literature as “Capo san Marco Formation”. Usually a quantify of calcareous sand was added up to 30%. By considering the conservation state of the calcareous grains and the presence of neo-formed phases, very different firing temperatures were deduced, from 650 to over 950°C approximately. The firings were always performed in oxiding atmosphere. As decorations are regarded, it was possible to establish that the presence of noticeable amounts of haematite is responsible of the red colour, while trace of manganese are responsible of the black colour.
