“…This pigment has been identified, by comparison, with the obtained Raman spectrum of a reference pigment previously characterized in other works, and also, this spectrum is consistent with the spectrum of the reference pigment synthesized and characterized by other authors . On the other hand, this triple oxide (with or without silica) has been identified in both, ceramics and paintings, with diverse methodologies such as Raman spectroscopy, X‐ray fluorescence, α‐particle‐induced X‐ray emission, and X‐ray diffraction …”

This investigation is focused on the identification in ceramic artworks of certain nonstandard yellow/orange pigments whose composition is based, fundamentally, on lead, tin, and antimony oxides with or without silica. In this work, a comparative study (temporal and geographical) of the employment of these yellow pigments in different production centers, from Italy (Pesaro and Montelupo) and Spain (Talavera de la Reina), during the Renaissance and Baroque epochs has been proposed. For this purpose, special very ancient yellow pigments were acquired from the Stazione Sperimentale del Vetro, Murano-Venezia (Italy). These reference pigments have been produced following strict and rigorous manufacturing recipes corresponding to Venezian fabrication processes for the 16th and 17th centuries. On the other hand, the portable characteristic of a new optical fiber Raman system has allowed us the access into the Museo de Cerámica de Barcelona in order to investigate the composition of the yellow and orange colors of an important ceramic collection belonging to this museum. The results are in good agreement with the ones obtained by other authors who have investigated the same topic. It is notable, first, the excellent performances that this portable Raman system offers in the direct and non-invasive analysis of ceramic artworks and, second, the coincidences of the molecular results among these yellow pigments. This fact confirms that these pigments were commonly used either in Italian and Spanish ceramic objects during both Renaissance and Baroque epochsPeer ReviewedPostprint (published version

“…PIXE has high sensitivity down to trace elements and has been extensively used in applications to cultural heritage because of its non‐destructive character . XRF was also used here in a few cases because of the availability of portable instruments; although it only allows the determination of the elemental compositions for elements heavier than sodium, it is also a very important tool for determinations of chemical composition …”

The first archaeological evidence reported for tile production in Portugal was discovered in Santo António da Charneca (SAC), late 15th or early 16th centuries' pottery kiln, south riverside of Tagus River. Samples from this kiln were studied with the use of non‐invasive spectroscopies, namely, μ‐Raman, ground‐state diffuse reflectance absorption, Fourier transform infrared and particle‐induced X‐ray or X‐ray fluorescence emission. These results were compared with the ones obtained for coeval tiles produced in Seville, Spain, originated from Portuguese archaeological sites, because it is well know that the Portuguese King Manuel the First imported in 1498 significant quantities of those tiles to decorate several palaces. The obtained results provided new spectroscopic insights, used to establish similarities but also clear differences regarding the SAC and the coeval Seville tiles found in Portugal. White glaze from both tiles gave evidence about the use of tin oxide as whitening agent and lead oxide as glassy agent. Cobalt oxides were also used as blue pigments in the two production centres. The brown and amber pigments in the samples from SAC derive from the manganese oxides dispersed in the lead–tin glaze, and kentrolite crystals were identified by μ‐Raman in these tiles. In the arista and cuerda‐seca tiles from Seville, diopside was detected. Divalent copper also exists in the green glaze matrix but in small amounts, which did not allow the Raman detection of the copper compound's microcrystals. However, diffuse reflectance measurements point to malachite green as responsible of green coloration. The Seville pastes contain calcium carbonate, although the SAC pastes do not evidence significant amounts of that compound in its composition. All the SAC pastes evidenced a high silica level, and quartz and anatase were clearly detected in the paste and possibly kaolinite. The Raman signals of orthoclase and calcium carbonate were detected in the Seville tiles. Copyright © 2014 John Wiley & Sons, Ltd.

“…The presence of a certain degree of microporosity is also reported in the literature for porcelains (Zucchiatti et al . ) and its influence on the totals should be carefully scrutinized. On the other hand, in the present work a normalization to 100 wt% (as suggested by Freestone) is not possible, due to the fact that the determination on Mg is only semi‐quantitative and Na is totally undetectable with the instrumentation used.…”

XRF Characterization Of 18th Century Piedmontese Porcelains From The Palazzo Madama Museum (Torino, Italy)

Around 100 porcelain objects of the 18th century Rossetti, Vische and Vinovo manufactures (Piedmont, Italy) from the Palazzo Madama Museum collection were analysed by means of an X-ray fluorescence portable detector. The present study represents the first chemical characterization of these early (1737-1825) European porcelains. Chemical composition data were submitted to multivariate clustering techniques that underscored a complete classification of the three manufactures and the presence of three subgroups for the Vinovo production. These resulting subgroups did not mirror the classification expected on the basis of the historiographic literature. The overall data pointed to technological continuity not only through all the Vinovo phases but even continuing from the earlier Vische manufacture.
