... (C) Subjective Judgement It is a matter of subjective judgement and taste whether a museumobject will appear satisfactory under tungsten light as well as under daylight, though the conservator should bear in mind that tungsten is one of the least damaging of light sources. ...

During the last decade, the environmental conditions of the museum exhibition facilities and storage areas have been shown to be the most crucial factor, concerning the preservation of collections and artifacts. The pollution (chemicals and noise), the humidity, the temperature and the lighting can possibly deteriorate or even destroy the material cultural goods that are kept, protected and displayed in museum collections. Therefore, the aim of the present report is to define the threats that museum collections may suffer under inappropriate ...

The outdoor sculpture of the first Portuguese king, D. Afonso Henriques (~1109 – 1185 AD), placed in Guimarães (North Portugal) is one of the most emblematic national sculptures. Created in 1887 by António Soares dos Reis, it possesses a remarkable symbolic value in the presumed birthplace of the king. In addition to the artistic and heritage importance of the monument, it is one of the few sculptures cast by a Portuguese industrial foundry in the 19th-century. This study obtained data on the sculpture's elemental composition and corrosion products, gathering important historical and technical information. For this purpose, a multi-analytical approach consisting of X-ray fluorescence (XRF), X-ray diffraction (XRD), optical microscopy (OM) and scanning electron microscopy (SEM-EDS) was carried out to characterise the bulk metal and corrosion layers. The data revealed a ternary alloy of Cu, Sn, Zn with Pb, Fe, As, Bi and Mn as minor elements. The alloy matches that of other sculpt...
