“…However, the exact nature of these crystallites has not yet been identified. Arsenium bearing cobalt blues have also been identified in Spain after the 16 th century [17,18]. A cobalt blue decoration found in Sant Bartomeu del Grau Catalonia and dating 16 th century AD, shows also a high amount of arsenic associated to the cobalt blue and the presence of large hexagonal crystallites of lead rich arsenates concentrated near the glaze-ceramic interface as shown in Figure 5.…”

“…A cor azul é obtida pelo uso de óxido de cobalto, cujo minério utilizado como matéria-prima tem a particularidade de conter diferentes combinações de elementos químicos que podem ser relevantes para obter informação sobre a proveniência e datação [34][35][36][37]. Na colecção de azulejos TRL, os vidrados azuis apresentam diferentes combinações de elementos associados ao cobalto, maioritariamente CoFe-Ni-Cu.…”

Palavras-chaveAzulejos hispano-mouriscos Vidrados plúmbicos Corpo cerâmico Composição química Características físicas Escavação arqueológica ResumoNeste trabalho estuda-se um conjunto de fragmentos de azulejos hispano-mouriscos do espólio do Museu de Lisboa -Teatro Romano. Apresenta-se a caracterização química e morfológica dos vidrados e do corpo cerâmico e a caracterização mineralógica deste último. Os vidrados são plúmbicos, sendo que os de cor branca e azul devem a sua opacidade a SnO 2 (4-11 %). As restantes cores apresentam teores de SnO 2 inferiores a 2 %. O corpo cerâmico é típico de pastas calcíticas, sendo os teores de CaO de 16-28 % e de Fe 2 O 3 de 4-5 %, este último responsável pela cor creme/ rosada. O estudo mineralógico permitiu identificar volastonite, calcite, diópsido e plagioclases cálcicas. Os resultados indicam que as temperaturas de cozedura foram geralmente próximas de 1000 ºC enquanto em alguns casos terão provavelmente estado mais perto dos 900 ºC. A caracterização física revelou valores de 30-42 % para a porosidade aberta, distribuição de tamanho de poros bimodal, absorção máxima de água de 16-26 % e coeficientes de absorção de água por capilaridade de 1,5-6,1 kg·m AbstractThis work intends to study a set of Hispano-Moresque tile fragments from the Lisbon Roman Theatre Museum collection. The chemical and morphological characterization of the glazes and the ceramic body was presented and also the mineralogical characterization of the latter. The glazes are plumbic, being the opacity of the white and blue colors due to SnO 2 (4-11 %). The other colors present amounts of SnO 2 lower than 2 %. The ceramic body is typical of calcite-based pastes with CaO between 16-28 % and Fe 2 O 3 between 4-5 %, the latter being responsible for the cream/ rose color. The mineralogical study identified wollastonite, calcite, diopside and calcic plagioclases. The results indicate that the firing temperature was generally around 1000 ºC while in some cases it was probably closer to 900 ºC. Physical characterization revealed values of 30-42 % for open porosity, a bimodal pore size distribution, a maximum water absorption of 16-26 % and a water absorption coefficient by capillarity of 1,5-6,1 kg·m

Composition and microstructure of maiolica from the museum of ceramics in Ascoli Piceno (Italy): evidences by electron microscopy and microanalysis

The present work focuses on majolica objects from the collection of the museum of ceramic in Ascoli Piceno (Italy). The scientific investigation was performed on fragments detached from seven maiolicas attributed to the Castelli production (Abruzzi region) and one majolica from the Ascoli Piceno production (Marche region). The Castelli artifacts (late sixteenth–early eighteenth century) belong to the decorated style known as ‘‘compendiario.’’ The piece from Ascoli Piceno recalls the decoration style of the other considered objects and is attributable to the\ud ‘‘Paci’’ manufacture (first half of the nineteenth century). The selected objects were investigated by fiber optics reflectance spectroscopy, micro-X-ray fluorescence spectroscopy and scanning electron microscopy coupled with electron-dispersive X-ray spectrometry. The ceramic bodies of all objects are calcareous, whereas the glazes are lead-alkali type opacified by tin dioxide. Blue and purplishred decorations were obtained by cobalt and manganese compounds dissolved in the glaze, respectively. Yellow and orange decorations were obtained by particles of lead antimonate and hematite. Finally, black decorations were\ud obtained using compounds rich in manganese and iron. The study contributes to knowledge on the production of Castelli ceramics and presents first archaeometric data on the maiolica production from Ascoli Piceno. The scientific examination highlights continuity with the Renaissance production, and the joint contribution of the three analytical techniques suggests distinctive features among different productions, thus integrating and refining the information obtained by the art-historical study
