Kirsten Meyer: Coated ephemeras of the 19. century and their preservation Back
Language: Original   -   Translation
Abstract: Besides the coating the coated ephemeras are characterized by an extensive design in different forms. The preservation of these objects is discussed by the baptismal sponsors’ greetings-collection of the Museum of European Cultures, Berlin. Often occurring damages are discolorations of orange-brown to black.
With the help of historical sources and natural scientific analysis lead white, used pure or mixed with other pigments, was determined as the cause of the discolorations. Endogenous and exogenous influencing factors are shown and in this context the used cladding material is evaluated by pollutant tests. Related to this, recommendations to reduce the pollutants are made and possibilities for the packaging are shown.
Hydrogen peroxide, used for the treatment of black discolorations of lead white, is applied for the reducing of the discolorations on sample materials and on a baptismal sponsors’ greeting. Afterwards this method is critically discussed concerning its suitability and necessity for baptismal sponsors’ greetings.
Comparing to the baptismal sponsors’ greetings, coated end-papers of books, which are from the holdings of the Duchess Anna Amalia Library, Weimar, and show discolorations as well, are described.
