Following a water damage in the Art and Literature Department at the Bibliothèque nationale de France (BnF), the question came of how to handle the wet glazed papers. The company in charge of freezing and drying the damaged documents was reluctant to take care of them because the quantity of water that impregnated each document was very variable. They knew from previous experience that if glazed papers were not totally soaked with water, the sheets would stick together and freeze-drying would have essentially no effect. As a consequence, we have to find a way to separate the sheets of glazed paper stuck together. We investigated the composition of the glazing, and found that most papers were glazed with Styrene-Butadiene latex. One of the solvents of SB latex is Tetrahydrofuran (THF). THF is toxic, but it can be replaced with a mix of ethanol and toluene (50/50 v/v). Tests were carried out on a sample of damaged documents. They gave excellent results on paper sheets which were locally stuck together. When the paper sheets were stuck on their entire surface however, the results were not as good, as the solvent also seems to have effect on many of the inks. Following these investigations, we were able to establish an emergency protocol applicable to massive amounts of wet glazed papers. In this presentation, we will report on our results and present the protocol that was established from our experience.

Paper conservator
I obtained a master's degree in Art History from the Ecole du Louvre (Paris), 1996. I then studied paper conservation at the Institut National du Patrimoine (INP-IFROA, Paris), from where I graduated in 2000. Shortly after my graduation, I was hired by the Bibliothèque nationale de France (BnF, Paris). I was first in charge of a book and paper conservation team and then specialized in the conservation of performing art documents (2D and 3D gouached paper documents, among which theater set designs, masks and various related drawings). I work primarily for the Departement des Arts du Spectacle (Performing Art Department), and occasionally for external museums, such as the Nouveau Musee National de Monaco (NMNM).
