Abstract
The present study investigates the stabilization of a 60 year old paper artefact via deacidification. Paper sheets originating from a naturally-aged artefact book were subjected to accelerated ageing performed at 98 °C during 0, 3, 5, 10 and 15 days. A set of samples were deacidified before being subjected to accelerated aging. Deacidification was performed using magnesium ethoxide and titanium ethoxide (METE) dissolved in hexamethyldisiloxane (HMDO) and the properties of the thus treated samples were measured and compared to control samples. This study aims at finding kinetic dependences for the decrease in the degree of polymerization and folding endurance of the paper subjected to accelerated ageing. The deacidification effects were evaluated by the folding endurance of the paper artefact through the multifactorial evaluation system developed by Consortium KnihaSK and Library of Congress.
