“…As stated above, Laurie was the first to note the differences in the gels formed in contact with limestones as compared to quartzrich sandstonessoft and "clumpy" with the former and hard and "glassy" with the latter. This difference was more closely explored by Charola et al (1984) and Danehey et al (1992). Charola demonstrated that fine calcite powders (approximately 200 mesh)a surrogate for highly deteriorated limestonewere poorly consolidated by methyltrimethoxysilane (MTMOS), while similarly fine powders of quartz formed tough monoliths.…”

“…In unpublished work following the model of Charola et al (1984), the author applied neat MTMOS dropwise to powdered quartz and calcite in small Nalgene containers until the powders were saturated. The containers were weighed periodically over the next few weeks.…”

“…Wendler postulated that such gels could not bridge gaps greater than 50 μm, even for minerals such as quartz that are receptive to consolidation with alkoxysilanes. The work of Charola et al (1984) cited earlier is relevant. They attempted to consolidate two grain sizes of quartz -"fine" quartz at approximately 75 μm and "coarse" quartz at approximately 400 μm.…”

This chapter is dedicated to Professor George W. Scherer of Princeton University, whom I first met at the Ultrastructure Processing of Advanced Ceramics conference in San Diego in 1987one of a series of conferences on sol-gel technologies organized by the late Donald Ulrich from 1984 to 1992. That meeting began a friendship and collaboration that has now spanned 30 years. Well known to sol-gel science, Professor Scherer also directed much of his prodigious intellect and energies to issues of cultural heritage preservation when he moved from industry to the university. Not only did he produce significant scholarship in understanding the deterioration and conservation of stone, and, mentored several in the next generation of scientists now pursuing similar subjects, he was and is generous with his time and knowledge in helping all of us to advance the field of science directed at cultural heritage preservation.

“…Para todos los ensayos se han usado muestras cúbicas de 5 cm de arista. Antes de aplicar los tratamientos las muestras se han limpiado, humedecido y secado al aire hasta alcanzar un contenido de humedad de 0-2 g; este procedimiento reproduce el estado de la piedra en el edificio y favorece la polimerización de los productos organosilícicos (16)(17)(18).…”

Fecha de recepción: 26-rX-95 ESPAÑA RESUMEN Este artículo recoge un estudio llevado a cabo sobre la Catedral de Granada que incluye la determinación de los indicadores, factores y mecanismos de deterioro. Asimismo se ha realizado una completa caracterización física y química del material alterado del edificio e inalterado de cantera. Se han probado ocho productos comerciales aplicados al principal tipo de piedra existente en el monumento, incluyendo la realización de dos ensayos de alteración acelerada (cristalización de sales y ataque químico con atmósfera de SOJ. Como punto final se recogen algunas recomendaciones de cara a una posible intervención.
