The manufacturing techniques of stained glass belonging to the Mosteiro de Santa Maria da Vitória in Batalha are being studied.

The characterization of fragments is performed by non-destructive analyses (micro-EDXRF,
micro-PIXE, micro-PIGE, UV-Vis spectrometries). The aim of the work is to determine the composition of the glass and respective paintings trying to establish the corresponding production periods.This study is a partnership between the Department of Conservationa and Restoration of the Universidade Nova de Lisboa and VICARTE with Mosteiro de Santa Maria da Vitória and the Portuguese Nuclear and Technological Institute.

Stained glass from Palácio da Pena

 

 

  

This window, dating from 1841, was ordered by D. Fernando II and produced in Nuremberg (Germany). The window is divided in 4 fields, each with episodes of the history of Portugal and of the monastery. Above, the armillary sphere, the cross of Christ and the real weapons of Portugal. The panels above depict Our Lady of Pena and Saint Jorge, patron of the Portuguese army. Below are represented the King Manuel I, holding a model of the original convent, and Vasco da Gama in the Tower of Belém.
The stained glass panels were covered with dirt (mainly dust and remains of animal presence). In some cases, the glass presented small fractures and was separated from the lead canes. The following methodology of conservation and restoration was followed, according to the Guidelines for the Conservation and Restoration of Stained Glass of Corpus Vitrearum Medii Aevii. Diagnosis: I) photographic record; Ii) mapping of main patologies; iii) characterization of corrosion products. The surface of the glass was first cleaned with soft brush and vacuum cleaner to remove the particulate and superficial dirt. After, wet cleaning with water and ethanol was performed. Traces of other materials were removed mechanically after laboratory analysis to determine their nature. Union of the glass fragments was made with Paraloid B72.
