Abstract
Publisher Summary This chapter discusses corrosion problems and reconstruction of the copper roof on Queen Anna's Summer Palace, Prague. The reconstruction project of the copper roof on the Summer Palace of Queen Anna in Prague is based on a systematic evaluation of corrosion and corrosion-mechanical manifestations, including measurements of the thickness of local residues on the copper sheets and analyses of surface layers from different exposure areas. Recommendations of a suitable technology for the repair and patination are supported by extensive laboratory and field testing. Good results were acquired through cooperation with the Czech monument care institutions and the restoration workshop. Results of long-term testing prove that artificial patinas (produced in workshops or industrially) are transformed into natural patinas, which are in balance with the surrounding environment. The rate and degree of transformation depend on the type of atmosphere, its corrosivity and its impact on the patina in particular outdoor environments. Periodic inspections of artificial patina on a historic roof proved the suitability of the aim of the restoration.
