Degradación ambiental de vidrios Modernos no equilibrados

Palabras clave: Vidrio, crizzling, ambiente natural, mecanismo de degradación

Resumen

El crizzling es una patología de alteración relacionada con vidrios no equilibrados (alto contenido de óxidos fundentes en relación con un bajo contenido de estabilizantes), que puede producir daños graves en las piezas como la pérdida de transparencia, la aparición de gotas en la superficie o la formación de (micro e macro-)fisuras. En este trabajo se presentan dos casos de estudio (ambientes exterior e interior). Se ha observado que el agente de alteración más importante para estos vidrios es el agua (lluvia, condensación y humedad ambiental). En el exterior, la lluvia lava los iones [OH] formados durante la alteración; sin embargo, su exposición a condiciones cíclicas aceleró su velocidad de alteración. En el interior, la higroscopicidad de los vidrios atrae la humedad ambiental produciendo la degradación.

Teresa Palomar, Instituto de Cerámica y Vidrio (CSIC)

Doctor in Chemistry in the Autonoma University of Madrid in 2013 and Master in Conservation Science in the Pablo de Olavide University (Sevilla) in 2016. She has developed her scientific career in the Spanish National Research Council (CSIC), the Spanish Centre Foundation of Glass (FCNV) and the Research Unit VICARTE "Glass and Ceramic for the Arts" (Portugal). Currently, she is a postdoctoral researcher in the Institute of Ceramic and Glass (ICV-CSIC) with a contract to the Program Comfuturo “Un COMpromiso público privado con la ciencia y el FUTURO”. Her scientific career has been focused on the conservation of inorganic materials from cultural heritage, especially on glass and metal. She has received the Special Mention in the Young Researcher on Conservation Science Award 2018 organized by the Spanish group of the International Institute for Conservation of Historic and Artistic Works.

Master and Ph.D. in Conservation and Restoration, specialization in Conservation Science, by Faculty of Science and Technology NOVA University of Lisbon (FCT-NOVA), in 2019.

She has developed her scientific career in FCT-NOVA (Dep. Conservation and Restoration and Research Unit VICARTE "Glass and Ceramic for the Arts"), in collaboration with national cultural institutions such as Museu Nacional de Arte Antiga and National Palace of Pena (Portugal). She is currently a research fellow on the project NanoCStoneH (collaboration between Instituto Superior Técnico, Universidade de Lisboa, and Instituto Politécnico de Setúbal) granted by the Portuguese Foundation for Science and Technology, focused on the development of nanocomposite materials for consolidation of carbonate stone, and a VICARTE research member.

Her scientific career has been focused on the conservation of inorganic materials from cultural heritage, especially on glass and stained-glass (study and characterization of collections; of materials and production techniques; and of glass corrosion processes), and currently also on stone preservation.
