In order to preserve a wooden icon belonging to the Transylvanian Ethnographic Museum collection the scientific expertise of the wooden support and of the picture materials (ground, pigments, binder and varnish) used for the "Virgin Mary with the Child" and "Diptych" diptych icons (8228 inventory number) was performed by FTIR spectroscopy, EI-MS spectrometry and DSC thermal analysis. FTIR spectroscopy and DSC methods offer information about the wooden support whereas EI MS and FTIR methods were employed for binder, varnish and pigments structural characterization. These structural data can be correlated with the artistic, theological and historical analysis of this religious patrimony object.

A triptych icon from the 18th century from Moeciu de Sus village, Braşov County, Roumania was investigated by physical-chemical destructive methods: Fourier Transform Infrared (FTIR) and Electron Impact Mass Spectrometric Techniques (EI-MS), as well as thermal analysis by Differential Scanning Calorimetry (DSC). There were identified: gypsum as ground, pigments from the painting layer (white, red and blue), binder (egg yolk for painting layer) and animal glue for ground and as varnish conifer resin. The triptych wooden support is lime (as being identified by FTIR and DSC techniques). The icon oldness was confirmed by the presence of Prussian blue, by the increasing of wood lignin/cellulose ratio and of the amorphous content of cellulose structure.

The processional flag is a cult object belonging to the churches. Nowadays, as well as it was in the past, the flag is carried by people, preceeding the religious processions; it is used on the occasion of bringing icons and holy relics from one place to another; the flag is also used at different ceremonial moments and at funerals. The Ethnographic Museum of Transylvania owns 10 processional flags in various conservation stages. Pigment samples were taken and we present the result of the samples expertise achieved by using the FTIR spectrometry, X-Ray diffraction, X-ray fluorescence and gas chromatography-mass spectrometry for the processional flag with the inventory number 8254. The results will be used to recommend several correct conservation and preservation methods.

The Saint Elijah's glass icon was investigated by FTIR and mass spectrometry methods for identifying the painting materials in order to preserve and restore it. The glass icon was realized in fatty tempera with egg yolk and vegetal oil was used as binder. The painting materials are as follows: red (lead minium), blue (Prussian blue), green (Prussian blue+ massicot), white (ZnO and lead white), yellow (massicot lead yellow, PbO), gypsum and Ca carbonate as color diluents.
