“…Mobile projectional radiography was the method of choice to determine the relics' authenticity, as the entire assemblages were too large and fragile for conventional computed tomography and hence required a technique without major displacement of the objects. Radiography is widely used and accepted by art historians, archaeologists, curators, and conservators, as this method enables information about the manufacturing process, compositional changes, and the condition of an object with minimal direct physical contact with the artifact itself (16)(17)(18).…”

“…Las medidas se llevaron a cabo con muestras en polvo en el rango 3° < 2Θ < 65° con un paso de 0,05° y 2 segundos por paso. Seguidamente, se empleó la base estándar de datos cristalinos del EVA para la identificación de fases (11,12 Estudio técnico de la decoración del techo perteneciente a la Sala Capitular del Ayuntamiento de Sevilla Seville City Hall Chapter Room ceiling decoration emitting standard D65 light. This instrument measured three variables of the surface studied to determine the CIEL*a*b* colour coordinates.…”

“…Measurements were taken on powdery samples in a 2Θ range of 3º-65º, with a step size of 0.05º at a rate of 2 seconds per step. EVA software was used to identify the crystalline phases (11,12). Las microfotografías de microscopía electrónica de barrido se obtuvieron con un microscopio Jeol JSM5400.…”

RESUMENEl objetivo de este trabajo es el estudio de diferentes aspectos, como el color, la composición química y las fases mineralógicas presentes en los diferentes materiales que forman la ornamentación del techo de la Sala Capitular del Ayuntamiento de Sevilla, mediante métodos físicos y quí-micos. Nuestros resultados muestran que el dorado fue realizado sobre una capa de bol previamente depositada sobre una lámina de blanco de plomo que cubría un estrato de calcita. Posteriormente, y probablemente debido a alteraciones en el dorado original, el techo fue de nuevo dorado usando una técnica similar. En el siglo XIX, casi todo el techo, excepto las zonas con inscripciones, fue blanqueado usando una mezcla de calcita y blanco de plomo. Se empleó plata para cubrir la espada del rey Juan I (casetón 27). Finísimas láminas de oro se usaron para decorar los atributos reales: coronas, cinturones, cetros, espadas y rosarios. En diferentes partes de la decoración fueron detectados pigmentos como azurita, malaquita, bermellón y negro de humo. La composición del mortero de la estructura era a base de cal y dolomita molida.Palabras clave: dorado, pigmentos, piedra, mortero, color. SUMMARYThe present article describes a chemical and physical study of the colour, chemical composition and mineral phases of the decorative materials in the Seville City Hall Chapter House ceiling. The findings showed that the inner most layer of material, calcite, was covered with white lead, in turn concealed under a layer of gilded bole. The ceiling underwent re-gilding, also over bole, due in all likelihood to wear on the original gold leaf. In the nineteenth century, the entire ceiling with the exception of the inscriptions was whitewashed with calcite and white lead. Silver was employed on King John I's sword (coffer 27). Gold leaf was used to adorn the royal attributes: crowns, belts, sceptres, swords and rosary beads. The high reliefs were likewise gilded. The pigments identified on the ceiling adornments included azurite, malachite, vermilion and gas black. A lime and ground dolomite mortar was used throughout.

“…The determination of the elemental composition of material is one of the primary interests from the archaeological point of view. Thus, the analytical X-ray spectrometry techniques are often used in the art and cultural heritage research [5][6][7][8][9].…”

The Migration Period on the present Polish territories is considered as a time of depopulation of Oder, Warta, and Vistula basins. The prerequisite for such assumption is lack of the archaeological finds in these regions. In contrast, on the Mrągowo Lake District and in the Lyna basin, one can find wealth of burial crematory equipped with items from the Roman period and made in the Germanic style. The analyses using the physics techniques gives an opportunity to the meeting of history with the contemporary times and the lost things may see the light of present day. The discovered artefacts may constitute a source of knowledge, which, after analysis, will be able to fill the gaps on the map of settlements in the Polish territories. The energy-dispersive X-ray fluorescence system was used to analyze the set of Polish archaeological artefacts found in an excavation in Masurian Lakes District. The compact X-ray tube developed in the National Centre for Nuclear Research (NCBJ) was used as an X-ray source in the system designed for the energy-dispersive X-ray fluorescence studies. The X-ray fluorescence spectra of the artefacts were registered with the Amptek SDD spectrometer and the concentrations of elements were determined. The measurements show that the X-ray system developed in NCBJ with transmission type X-ray tube and the Amptek SDD spectrometer is an effective tool for chemical composition analyses of archaeological objects and can be successfully applied in archaeometry.
