Abstract
[spa] El papel por ser higroscópico y dada su composición orgánica es susceptible al deterioro, por ende, resulta de gran importancia saber proceder en cuanto a su correcta conservación-restauración. Uno de los problemas comunes en los materiales de patrimonio celulósico es la presencia de manchas de foxing, las cuales son más ácidas y menos resistentes que el papel circundante. El presente trabajo realiza una revisión de la literatura acerca de los estudios realizados sobre dicha mancha. Varias teorías han surgido intentado dar una explicación a su formación, no obstante, su causa aún no se comprende completamente. Hasta el momento, su formación se ha atribuido a causas bióticas (microbiológicas) y abióticas (metales pesados y/o oxidación). Gracias a esta revisión se pretende conseguir un mayor conocimiento sobre cómo actuar en caso de estar presentes en un sustrato de papel. Para ello, se han recopilado varios estudios acerca de la naturaleza de la mancha, se mencionan técnicas analíticas de las cuales se dispone antes de proceder a su intervención y se sugieren métodos de tratamiento.
[eng] Because paper is hygroscopic and given its organic composition, it is susceptible to deterioration, therefore, it is of great importance to know how to proceed with its correct conservation-restoration. One of the common problems in cellulosic heritage materials is the presence of stains from foxing, which are more acidic and less resistant than the surrounding paper. The present work carries out a review of the literature about the studies carried out on this stain. Various theories have emerged that have attempted to explain its formation, however, its cause is not yet fully understood. Until now, its formation has been attributed to abiotic biotic (microbiological) causes (metals and / or oxidation). Thanks to this review, it is intended to obtain a greater knowledge of how to act in the event of these stains being present on a paper substrate. To do this, several studies have been compiled about the nature of the stain, analytical techniques that are available before proceeding with its intervention and treatment methods.
