Este trabajo corresponde al estudio de dos paneles de vidriera de pequeñas dimensiones datables estilísticamente como de inicio del siglo XV. Corresponden a dos escudos de armas, recientemente restaurados procedentes de la capilla de San Pedro Mártir de la Basílica de San Petronio, en Bolonia (Italia). Para proceder al estudio se ha realizado un mu...

The chemical composition of nine medieval coloured stained glasses from Duomo (Catedral) of Siena, Italy, has been characterized. They come from the rose window elaborated under the drawing of Duccio di Buoninsegna masterwork (1288- 89 AD). This note explains the results obtained by EMPA, representative of bulk chemistry of several coloured glasses...

Article
A set of 35 samples from the rose window of the Siena Cathedral (Tuscany, Italy) has been studied using EMPA to define the chemical composition (17 major and minor elements) of the base glass. This paper focuses on colourless and natural-coloured glasses, i.e. glass produced without the intentional addition of colouring agents. The presence of natu...

This paper offers new insights on the evolution of colour recipes for Na-rich Mediterranean stained glass, taking as a guideline the results of the study of the Duccio di Buoninsegna's rose window (1288e89 AD) at the Duomo (Cathedral) of Siena (Italy) and the Santa Maria de Pedralbes presbytery windows of the church at the royal monastery in Barcel...

... They separate into four tight compositional clusters that appear to represent the same objects, judging from the standard deviations of each sub-group that is within the limits of analytical uncertainty across all elements (Fig. 10). All four sub-groups are compositionally close to thirteenth-to fourteenth-century glasses from Montpellier and Perpignan (France, unpublished data) and contemporaneous stained glass windows from the Santa Maria de Pedralbes presbytery at the royal monastery in Barcelona (Gimeno et al., 2008) (Fig. 9). These are all places of consumption, hence we still do not know where the finished objects were made, although regional workshops are very likely. ...
... In the case of purple glasses, the colour results from the presence of Mn 3+ ions in the glass (Bamford, 1977;Bidegaray et al., 2019;Capobianco et al., 2019;Hunault et al., 2021). It is also used for depicting skin complexion in stained glass windows (e.g., Basso et al., 2009;Capobianco et al., 2021;Hunault et al., 2021;Palomar, 2018;. It is of interest that, in other glass-containing materials such as enamels (Biron and Verità, 2012) or tesserae (Verità and Santopadre, 2010;Schibille et al., 2018), a flesh tone colour has also been achieved by using thin layers coloured by gold nanoparticles deposited on a white enamel. ...
... Examples of artifacts attributed to craftsmen from Celtic (Brun et al. 1991), Roman (Freestone et al. 2007), and Chinese (Huaizhi and Yuantao 2000) antiquity have been found to include metal nanoparticles. These ancient techniques were carried forth into the medieval period where metal colloids were used in the manufacture of stained glass windows in cathedrals (Perez-Villar et al. 2008;Rubio et al. 2009;Gimeno et al. 2010). ...
... On the other hand, intentional input of manganese was added to decolourise the glasses (Fig. 10). Manganese as a decolouriser is acknowledged to be used in Tuscan glass recipes by the end of 13th century (Gimeno et al., 2008;Gimeno et al., 2010). ...
