Until the present the main achievements of this project where: the first results obtained from the analysis of some of the most iconic King's collection of stained glass panels D. Fernando II; the historical reconstruction of stained glass paint materials according to the treaties of the time; research in documentary sources and on glass and stained glass suppliers at the European level, which have made important contributions to the project. Finally, during this first year two doctorates in Conservation and Restoration were initiated: Andreia Machado (SFRH/BD/78882/2011) and Alexandra Rodrigues (SFRH/BD/84675/2012).
Research of archive documentation
The ongoing investigation in Torre do Tombo focuses on the collection of private documents of the members of the royal household (Cartório da Casa Real). Regarding the stained glass collection the correspondence of Baron of Eschwege, he played an important role as initiator of the stained glass collection, in mentoring the project and in providing several panels from northern Germany.
Iconography study and decoding
The results of the iconographic studies of these panels were made available to the general public through MatrizNet. Furthermore, several original engravings used for the painting of these panels were identified.
Analytical characterisation of glass composition, decoration elements and corrosion products
Until now a total of 20 stained glass panels and 30 stained glass fragments have been analysed by EDXRF and PIXE/PIGE. According to analysis the fragments belong to the groups of potash, mixed alkali and high lime low alkali glass. A multivariate analysis approach is being tested to enlarge the data considered to quantify the similarities and differences between specimens and groups of specimens.
Historical painting techniques of stained glass
The study and reproduction of blue enamels and sanguine red was accessed based on the information given by the recipes and recent contributions to their study. Fiber Optics Reflectance Spectroscopy, with colorimetric analysis, on both blue enamel paintings and sanguine red reproduced and present in stained glass panels was performed.
