In this work TiO2 and ZnO layers have been deposited by screen-printing in common glazed ceramic tiles. These layers were evaluated for the photocatalytic degradation of Orange II in aqueous solutions, in a batch photoreactor under visible light. The photocatalytic behaviour was assessed by taking into account experimental variables which include: (i) firing temperature of the TiO2 printed layer; (ii) layer thickness; (iii) operation time; (iv) pH; and (v) dye concentration. Optimal processed layers showed an interesting decolourisation performance (over 90% efficiency after 7-8 h). It is anticipated that these new ceramic materials might be developed as an interesting alternative to TiO2 or ZnO suspensions, for example in photocatalytic applications excusing the particles removal at the end of the process.

<p>The possibility of using geopolymers to fill gaps/lacunae in glazed ceramic tiles (azulejos) has been studied. Since the 15<sup>th</sup> century, glazed ceramic tiles are characteristic elements of the Portuguese architectural heritage and their use as external rendering elements has made them prone to degradation. On the other hand, civil construction is a sector with a high consumption of natural resources and CO<sub>2 </sub>emissions. In order to respond a necessary increase of sustainability in conservation/restoration processes, it is important to create/use sustainable repair materials that also ensure compatibility and durability of interventions. Geopolymers were studied as a potential sustainable and compatible repair material. Two commercial metakaolins ARGICAL-M 1200S and ARGICAL-M 1000 were used as precursors in geopolymer pastes and tested. The purpose of this research was to assess the potential of geopolymers in the restoration of the glazed ceramic tiles, both in the filling of gaps and the bonding of ceramic fragments. The physical, chemical and mineralogical analyses of these materials were performed. Additionally, in order to evaluate possible use in conservation interventions, tile lacunae filling, glazing reintegration and bonding of ceramic fragments were studied. Several tests were performed in order to analyse the compatibility and durability of the designed geopolymers and the ceramic/geopolymer system. The results suggest that the geopolymers had a better performance in the bonding of ceramic fragments and can have potential to be applied in the conservation and restoration of tile facades. Thus, as a general conclusion, it was possible to develop sustainable materials to apply in conservation of buildings facades.</p>

Historical Periods

In Portugal, the use of azulejos (glazed ceramic tiles) in architecture has a long history, extending uninterruptedly from the late 15th century to the present 21st century. For more than five centuries, the azulejo reinvented itself periodically to meet the demands of different historical periods, and one of its most expressive transformations took place in the Baroque period (1675–1750). Baroque azulejos stand out not only for the almost exclusive use of blue and white painting, but above all for the exploration of narrative programs, which were displayed in vast ceramic walls. These decorations covered the interiors of different buildings, but mostly churches. The use of azulejos, dominating the interiors or in connection with other arts, was instrumental in creating a unique spatial form, which echoed Baroque spirituality by appealing directly to the senses and exploring the brightness and color of the tiled surfaces within majestic and lusciously decorated settings. But the azulejo was also a medium for religious painting and, as such, a vehicle for the doctrine and values of the Counter-Reformation, which were dominant at the time. Therefore, these ceramic architectural programs resort both to devotional and visual discourses. On the one hand, azulejo compositions relate to central aspects of Christian faith and liturgy, and particularly to the religious discourse and practice of the Baroque period. On the other hand, their visual features add new layers of meaning, mostly related to the organization of azulejos within a church’s architecture, the frames and inspirational sources, as well as issues linked with the creation and running of azulejo workshops.
