Research and restoration of an archaeological set of Renaissance glass from the historical collection of the National Museum

The studied set of archaeological Renaissance glass originates from salvage research related to the construction of the metro in the centre of Prague in 1966. According to contemporary records, it was collected at the intersec­tion of Opletalova Street and Vrchlického sady, in the vicinity of archaeological sites, among others with a fixed early modern reservoir. Chemical analyses confirmed that, with one exception, the glass finds were made from potassium-calcium glass. It therefore belongs among typical glasses of domestic regional production between the middle of the 16th and the end of the 17th century. Part of the find was in a fragmented state, while part had already undergone an earlier conservation intervention. Given the time since the first intervention, the previous gluing was not strong enough and the accessories unsightly. The glass was contaminated with dust and damaged by corrosive processes. During the newly-realised intervention, the set of Renaissance glass was successfully restored using modern methods. For the sake of spatial stabilisation, supporting crosses were constructed for the four torsal ob­jects, which today enables them to be displayed effectively. The work is an exemplary result of the collaboration between the National Museum and the Institute of Glass and Ceramics of the University of Chemistry and Tech­nology in Prague, where the restoration was carried out as part of student seminar work.
