Fungal biodeterioration of stained-glass windows

An integrated approach for assessing the bioreceptivity of glazed tiles to phototrophic microorganisms

“…Regarding the biochemical attack on the glazed surface, corrosion products such as carbonates, common corrosion products of silicate glass (Rodrigues et al 2014) and ceramic body (Maguregui et al 2009), were identified after the colonization experiment. However, carbonates were also present on the control samples.…”

“…Tiano et al 1995;Miller et al 2008Miller et al , 2009aMarques et al 2015). These approaches were developed for stone, glass, unglazed ceramics and concrete materials, providing important data on their bioreceptivity and mechanisms of biodeterioration (Ranogajec et al 2008;Miller et al 2009b;Herisson et al 2013;Rodrigues et al 2014). No laboratory studies have been performed to assess bioreceptivity and biodeterioration of majolica glazed tiles.…”

Biodeterioration of majolica glazed tiles by the fungus Devriesia imbrexigena

“…However, laboratory-based inoculation experiments are fundamental to understand biodeterioration processes and to relate material properties with susceptibility to microbial colonization [12]. Fungi are responsible for the decay of many types of building materials [13][14][15]. Laboratory tests on unglazed ceramic roof tiles have shown that fungi are able to form bioprecipitates and penetrate into pores affecting the material integrity [16,17].…”

“…Laboratory tests on unglazed ceramic roof tiles have shown that fungi are able to form bioprecipitates and penetrate into pores affecting the material integrity [16,17]. In addition, several studies focused on stained glass windows from cultural heritage assets [18][19][20] and laboratory-based colonization experiments [14,15,21,22] have provided important insights into glass biodeterioration by fungi, showing that they able to cause glass biocorrosion. Yet, studies on the biodeterioration of glazed tiles have mainly focused on the identification of colonizing microorganisms [4][5][6]8,10] and no laboratory experiments have been performed on fungal biodeterioration of historical glazed ceramic tiles.…”

Energy use and indoor climate of conservation heating, dehumidification and adaptive ventilation for the climate control of a mediaeval church in a cold climate

“…Availability of water or high relative humidity (RH) is the most important precondition for microbiological growth (mould, bacteria, and algae), decay, or soiling of surfaces, condensation on or within materials. Microorganisms on the surfaces can cause structural and aesthetic damage of paintings, stucco, wooden objects or even stone and stained-glass windows [4][5][6][7][8].…”
