Language: Original   -   Translation
Minute-sundial D I 7
Abstract: The Mathematisch-Physikalische Salon of the Staatliche Kunstsammlungen Dresden owns a minute-sundial with the Inventory number D I 7. Over time black discolorations emerged on the gilded brass surface of the dials. In this bachelor thesis these discolorations were material-specific identified and investigated with the Ion Beam Analysis. Special attention was placed on the analysis of the development, to prevent a reoccurrence of the discoloration on other objects.
It is considered to remove these black discolorations as a part of a future restoration. Therefor various techniques to uncover the surface have been tested and documented on samples, to develop an appropriate concept for restoration.


Keywords: minute-sundial, Mathematisch-Physikalische Salon, black discolorations, Ion Beam Analysis, Investigations, techniques to uncover the surface
