| Popis: | The results of a research project on verdigris on paper have been applied in the conservation of a celestial atlas and a series of printed books with images of cities in Renaissance time. Paper degraded by verdigris was chemically stabilized by applying a solution of benzotriazole, a copper complexing agent, in ethanol by brush from the verso. Tears and brittle areas were mechanically stabilized with pre-coated Japanese tissue papers. The copper ion content and the effect of complexation were monitored with self-prepared copper ion indicator papers. Paper samples with different concentrations of benzotriazole were light-aged to evaluate the effect of yellowing. |
