“…Manganese appears associated with higher iron contents. Barium also appears associated with manganese in approximately half of the samples, is frequent in manganese-brown decorations (Coentro et al 2012(Coentro et al , 2014Molera et al 2013) and has been attributed to the Ba-containing minerals (Ba-feldspars, psilomelane (Ba,H 2 O) 2 Mn 5 O 10 ) and barite BaSO 4 ) that are abundant in manganese ore sources (Tite et al 2009). Figure 6 illustrates the typical glaze and glaze/ceramic interface found in white and blue glazes.…”

The Glaze Technology of Hispano‐Moresque Ceramic Tiles: A Comparison Between Portuguese and Spanish Collections

et al. 2017

For the first time, Hispano-Moresque glazed tiles from Portuguese and Spanish collections were studied together and compared. This work is included in a wider study tackling the technology of Hispano-Moresque tile production from several collections in the Iberian Peninsula. While showing many similarities, differences were identified between collections, regarding both chemical and morphological characteristics. The collection from the Mosteiro de Santa Clara-a-Velha (Coimbra) stands out from the other collections, with higher SnO2 content (up to 14¿wt%), the highest Fe2O3 contents in amber glazes and a Ca-rich interface layer (mostly comprised of wollastonite, CaSiO3). Samples from Palácio Nacional de Sintra (near Lisbon) and Seville-attributed samples (from the Instituto Valencia de Don Juan) are chemically similar, except that most Sintra's samples display a K-rich glaze/ceramic interface, whereas the ones from Seville exhibit both K-rich and Ca-rich inclusions. The samples attributed to Toledo show glazes with many inclusions, contrasting with the homogeneous glazes in most Hispano-Moresque tiles. From these results, we identify differences that can be used as markers in future studies on Hispano-Moresque tiles.Peer ReviewedPostprint (author's final draft

“…These two manganese minerals correspond to two important and worldwide distributed manganese sources (Coentro et al, 2012;Pérez-Arantegui et al, 1999). However, Tite et al (2009) pointed out that this assumption represents an oversimplification, pointing to the wide range of Mn minerals in nature, together with veins of (Fig. 3a).…”

a b s t r a c tA group of late 15theearly 16th century Hispano-Moresque glazed tiles from the Monastery of Santa Clara-a-Velha, in Coimbra, were, for the first time, characterised chemically and morphologically. Since the prevailing idea among art historians in Portugal is to judge the Hispano-Moresque tile heritage as Spanish production, the findings concerning technological processes were compared with the Islamic technology in the Iberian Peninsula and latter Hispano-Moresque in Spain. This study is the first analytical indicator of a production technology with some differences from the Hispano-Moresque workshops (such as Seville, Toledo, etc.) and points out to a possible local production. Five different coloured glazes were identified: white, blue, green, amber and black, all displaying high-lead content, as expected for this type of ceramics. Tin oxide was identified in high contents (7e14 wt.%) in white and blue glazes, its crystals homogenously distributed in also very homogeneous glazes, showing similarities with an Islamic glazing technology. On the other hand, Ca-rich thick glazeeceramic interfaces were observed, with many mineral inclusions (wollastonite (CaSiO 3 ) and also K-feldspars (general formula KAlSi 3 O 8 ), showing a higher resemblance with a later Hispano-Moresque technology. Other compounds were also identified from reactions involving the colour compound: malayaite (CaSnOSiO 4

SCIENTIFIC INVESTIGATION OF FAIENCE FRAGMENTS ATTRIBUTED TO THE TOWN MOSAIC AT KNOSSOS*

We analysed a faience fragment from Bristol Museum and Art Gallery, to determine whether it belonged to the Town Mosaic, excavated at Knossos. Three Town Mosaic fragments from the Ashmolean Museum, Oxford were also examined. The objects were analysed using nondestructive variable-pressure scanning electron microscopy with energy-dispersive X-ray spectrometry. The Bristol object's composition and microstructures are similar to those of the Town Mosaic samples. Our results are also comparable to those from polished samples of Minoan faience (Tite et al. 2009), showing that VP SEM-EDX gives reliable results without invasive sampling. Silicaceous, copper-rich microspheres were identified for the first time in two of the Ashmolean objects.
